The Importance of Preventative Roofing Maintenance

Roofing is a challenging and exciting form of building construction. It is the primary barrier that protects a structure from the elements.

The oldest roofs were constructed from thatch, which used dried vegetation such as straw, reed, or heather. These were flammable and required regular maintenance. Contact Erie Roofing now!

A roof’s peak is called a ridge, while its bottom edge is a sloping eave. Where two sloping roof surfaces meet, they form a valley.

Roofing has existed as long as humans have needed shelter from the elements. As soon as early pre-historic hunters and gatherers began to venture outside of their caves, they found the need to build a more permanent shelter that would offer protection from rain, snow, wind, sunlight, and extreme temperatures. It’s safe to say that roof construction has been a continuous process of evolution ever since.

The first roofing materials were quite basic, utilizing whatever was available in the environment around them. This included animal skins, branches, sticks, and mud. As societies advanced and technology evolved, other more durable and fire-resistant materials began to be used. Clay tiles were one of the earliest advancements in roofing, dating back to 10,000 B.C. and eventually becoming a staple in Mediterranean architecture.

Thatching is also a very ancient technique, involving the use of dried plant material such as straw, reed or heather to cover a building. While this offered some insulation benefits, it did not protect against fire and could become prone to rot. Wood shingles were another development in roofing, but it wasn’t until the 1800s that people started to treat them with pine pitch and linseed oil to help slow down their deterioration and add weather resistance.

Roofing has come a long way from being merely a means of protection to now playing an important role in the overall aesthetics of a building. Whether you are looking for an energy efficient metal roof or a decorative cedar shingle, you’ll find that there are plenty of options to meet your needs and fit your personal style. As the industry continues to evolve, you can expect it to continue to adapt and expand in order to meet the demands of modern homeowners.

Materials

The roof is the outermost layer of a building’s structure and shelters it from the elements. There are many different roofing materials, and each has its own advantages and disadvantages. These can include initial cost, durability and environmental impact. Traditional roofing materials such as thatch, straw or clay tiles add natural beauty to a home while also offering good durability and long lifespans. Other options include corrugated galvanised iron (sometimes known as “Corro”), wood shingles and built-up roofing (BUR).

The type of roofing material chosen for a building often depends on local climate conditions and the availability and cost of different products. A typical suburban shingle roof may be made from asphalt and last up to 30 years, while a slate or clay tile roof can last 50 to 100 years or more. These longer-lasting options tend to be more expensive than other choices and require a strong structural foundation to support them.

Other less-common roofing materials include membrane roofs that use durable ethylene propylene diene monomer (EPDM) or thermoplastic sheets to create a watertight barrier on low-slope or flat areas of the roof. These are more common on commercial buildings but can be used for residential roofs in some situations.

Other materials, such as coir or coconut fibre mats, are typically used to insulate low-rise domestic and light industrial structures. They are also commonly used in tropical regions to protect against high rainfall. These types of materials are also relatively inexpensive and easy to install.

Installation

The roof is an important part of a house or building. It serves multiple purposes, protecting the structure and its inhabitants from diverse weather conditions such as rain, snow, cruel UV rays, and strong winds. The roof is also a critical aspect of indoor comfort, allowing for a comfortable temperature and eliminating water leaks that can damage interior furnishings.

The installation process of roofing is a complex project that involves careful planning, preparation, and installation. During the inspection phase, our experienced roofing contractors will examine your roof and assess any damage or areas that need improvement. They’ll also discuss any costs that may be associated with the repairs or replacements and work within your budget to find the best solutions.

Once you’ve agreed on the price and terms, our roofing contractors will get to work on your roof. They’ll start by removing any existing covering and setting up protective measures on your property to prevent debris from falling and damaging plants, shrubs, or vehicles. Tarps will cover any outdoor structures, and open drains will be covered to prevent small pieces of debris from getting stuck in them and causing a blockage.

During the installation phase, our contractors will place the underlayment across your entire roof surface, attaching it to the roof deck with a nail pattern that’s close together near the edge and spread out more toward the center. They’ll then place the shingles on top of the underlayment, overlapping each row by about six inches and nailing them down firmly.

Maintenance

A roofing system is a significant investment for any home or business, and it’s important to protect this investment. Preventative maintenance is essential, as unplanned repairs cost 3 to 9 times more than planned ones. Performing regular inspections of the roof will prevent small problems from becoming more severe.

The inspections should include looking for shingles that are loosened or missing, holes and dents and the integrity of the caulking around the flashing and vent pipes. It’s also a good idea to look for moss or lichen, which are signs of moisture and decay beneath the shingles. The inspections should be done each season, as each one brings different weather patterns. Summer heat and humidity could lead to excessive sun damage, while winter storms could result in leaks from melting snow.

It’s important to clear the attic of twigs, leaves and other debris that could block rainwater from draining properly. It’s also a good idea for homeowners in areas with high winds to trim tree branches that could fall on the house or cause other damage during heavy storms.

Performing routine roof maintenance can also help homeowners save on energy bills. A well-maintained roof provides effective insulation against the sun’s rays and other elements, keeping the indoor temperatures comfortable. It can also prevent water leaks that can cause major structural and cosmetic damage to the building and lead to expensive repairs and replacements.

Repairs

Aside from replacing shingles, roof repairs include the replacement of worn-out materials like tar paper and flashing. They can also seal cracks, holes and gaps to prevent leaks. Repairing these minor issues is much cheaper than re-roofing and can help you avoid major damage in the future.

A full roofing replacement can be necessary if your roof is showing signs of major wear-and-tear, including severe leaks and mold growth. It can also be expensive because it requires a lot of time and labor to dismantle the existing roof and install a new one. However, if your roof is still in good condition, you may only need to replace a few shingles or repair minor leaks.

Some roofing repairs require the use of specialized tools. For example, a pry bar is useful for prying and leveraging sheathing, roofing and flashing. Roofing cement is used to fill cracks and encase damaged flashing. Nails and shears are also important for roofing. A roofer should have all these tools in their toolbox for routine maintenance and repairs.

If your roof has been subject to heavy snow buildup or punctured by falling limbs, it may need repair. These issues can be resolved with proactive repairs or by installing a gutter system. You can also invest in a maintenance plan with your roofer for annual inspections and priority repairs. This will ensure that your roof is in top shape and can withstand severe weather conditions. It will also keep your warranty valid and give you peace of mind.

Flat Roof

A roof is a protective cover that prevents rain, snow and sunlight from entering homes and commercial spaces. It can also serve a variety of security and aesthetic objectives.

Most people think of their roofs only in terms of the materials like shingles or tiles. However, there is more to a roof than that. The roofing structure is the frame that supports the roof covering. Visit our Website to learn more.

Flat roofs are less common than sloped roofs, but they’re still a great choice for many homeowners and commercial building owners. Depending on the material used, they can provide good insulation and a durable weather barrier. Additionally, flat roofs can be a space for solar panels or even a rooftop garden.

Although the term “flat” is misleading, a true flat roof has a very low pitch. The pitch is typically between 1/4 inch and 2 inches per foot. This is very little of a slope, and it requires very different materials to stay watertight than medium or high pitched roofs.

Because of this, flat roofs tend to require more maintenance and are more prone to leaks than sloped roofs. It’s important to have a roofer regularly inspect flat roofs so they can catch any potential problems early and prevent damage to the roof structure and the building below.

Leaks in flat roofs can go unnoticed for a long time, and they’re harder to repair than leaks in sloped roofs. When a leak does occur, it’s often because the waterproof membrane has been penetrated. When this happens, the underlying roof decking is soaked, and it can begin to sag. This can cause expensive structural damage, and it can also lead to rot and mold which threaten the health of anyone who breathes in the mold spores.

Another issue with flat roofs is their vulnerability to high winds. If a strong gust comes through, it can easily tear up shingles or even damage the roof structure itself. This is why it’s important to ensure that any potential problems are fixed before high wind conditions come through.

There are many different types of materials that can be used to construct flat roofs. Some of the most popular options include EPDM rubber, TPO plastic, PVC plastic, and built-up asphalt. All of these have their own sets of benefits and drawbacks, so it’s a good idea to research each one before deciding which is right for you. Another advantage of a flat roof is its ease of access, which can make it more convenient for maintenance and repairs.

Agable Roof

Gable roofs are an attractive feature of many homes. The triangular shape with a peak is instantly recognizable, making this style of roof perfect for those who want to give their property a unique look. In addition, a gable roof is a great option for areas that experience heavy rainfall because it allows water and snow to flow off the roof more easily than other types of roofs. This is especially helpful in cold climates, where a properly constructed gable roof can reduce the risk of water damage and maintain the structure of the building.

A gable roof can be designed in various ways. Some designs use an open gable, where the sides of the triangle remain unfinished, while others incorporate closed sections at the top of the roof, called gables. The most popular type of gable roof is the cross-gable or Dutch gable, which has two gables intersecting at a right angle.

Both the open and the cross-gable roofs allow for extra attic space, which can be used to install dormers or other windows in a home. These dormers can provide more natural light to the interior of the house and also improve air circulation by letting more fresh air in. In addition, gable roofs can be modified with different kinds of ornamentations like brackets and pediments to add more elegance to the exterior of the home.

As a practical feature, gable roofs are strong enough to hold a lot of snow and can be fitted with insulation for better energy efficiency. They are also less expensive than other types of roofs, and can be crafted out of a variety of materials, including asphalt shingles, metal sheets, clay or concrete tiles, or cedar shakes.

The gable roof is an excellent choice for those who want to increase the value of their property, as it can be fitted with dormers, allowing homeowners to turn the attic into a more usable area. However, they are not as suited for cold climates as other roofing styles, and may need to be fitted with special ice dams and other protective measures.

Shingle Roof

The shingle roof is what most people think of when they hear the word “roofing.” While there are a variety of different roofing materials, asphalt shingles are the most popular because they’re affordable and durable. They also come in a variety of colors, and are easy to work with when designing the look of a home’s exterior.

There are two main shingle types, 3-tab and architectural. 3-tab shingles are flat and uniform, while architectural shingles have a multi-layered design that adds a more dimensional aesthetic to the roof. Skywalker Roofing recommends the TruDefinition Duration shingle line from Owens Corning, which features dramatic color contrast and comes with a limited lifetime warranty.

Shingles are designed to be energy-efficient, which reduces a homeowner’s electric bill. The shingles’ color plays an important role in this; dark-colored shingles absorb the sun’s infrared radiation, which raises the attic space temperature. Light-colored shingles reflect the heat, keeping the attic cool and decreasing energy consumption.

In addition to being energy-efficient, shingles are impact and fire-rated, which protects the roof from external damage. Additionally, shingle roofs are quieter than other roofs and provide protection from external noises like rain and hail.

While shingle roofs are very durable, it’s important to keep up with maintenance and repairs to ensure your home stays safe and secure. Depending on the material, shingle roofs can last up to 30 years if properly maintained.

If you notice granules collecting in your gutters, or around downspouts, it’s time to call for a roof inspection and repair. While granule loss is normal, it’s an indication that the shingle materials are beginning to wear down. If left unchecked, this can lead to leaks and other structural issues.

If you are concerned about your shingle roof, call our team today for a free estimate. We can help you determine the best course of action, from a quick repair to a full replacement. We’ll be happy to answer any questions you may have along the way. We also offer a wide range of other residential and commercial roofing services, including roof installation and repair, roof replacement, gutter system replacement, and emergency roof service.

Metal Roof

Metal roofs are a popular choice for homeowners because of their durability and longevity. They can also provide energy efficiency and help protect against fire, hail and other extreme weather conditions. Metal roofs are available in a wide range of styles and materials, including steel (galvanized, galvalume or weathering), aluminum, copper and zinc.

A metal roof is more lightweight than other roofing materials such as tiles and asphalt, which helps reduce the stress on the roof structure and house foundations. Additionally, metal roofs are easy to clean and require little maintenance. However, it’s important to hire a professional roofing team to install a metal roof to ensure its safety and longevity.

Unlike shingles, which are installed with a nail gun, most metal panels are fastened using screws. The type of screw you choose will depend on the manufacturer’s recommendations. It’s important to use high-quality screws that are made of stainless steel, which is more resistant to corrosion. You should also ensure that all screws are properly placed in the raised ribs of the metal panels to prevent water infiltration and avoid over-tightening.

Another consideration when selecting a metal roof is its pitch. A steep roof is harder to cover and will increase your installation costs. If you choose a metal roof with a pitch greater than 3:12, it’s best to add a ridge cap at the peak to prevent rainwater from seeping in through the top of your home.

You’ll also need to purchase accessories for a metal roof, such as flashing, trim and pipe boots. These items are often included in the installation estimate provided by a professional roofer. However, if you’re installing the roof yourself, it’s a good idea to order 10-15% extra material to account for mistakes and waste.

If you’re thinking about installing a metal roof, research the various brands to learn about their warranties, quality and performance. You should also look for a metal roof that’s tested, labeled and listed with an organization like UL, FM Approvals or Intertek to ensure it meets rigorous wind, fire and impact resistance requirements.

What Is Roofing?

Roofing is the top covering of a building, protecting it against rain, snow, sunlight, and temperature extremes. It can be flat, pitched, vaulted, or dome-shaped.

A good roof should be long-lasting, easy to repair, fireproof, and easy to install. It should also have good insulation properties to save energy. Contact Metal Roofing Missoula now!

Waterproofing is a process that helps protect structures from deterioration and damage caused by rain, snow, ice, or other weather conditions. It also helps to prolong a building’s life. Waterproofing can be done on roofs, walls, basements, or any structure exposed to the elements. There are many different waterproofing materials, including liquid-applied membranes, bituminous coatings, and elastomeric coatings. Depending on the type of structure, the waterproofing material will be selected to meet specific needs.

Whether it’s a flat or pitched roof, it is essential to have a high-quality waterproofing system in place to prevent leaks and other problems. Leaks can cause structural damage, mold growth, and even electrical issues. This can be extremely costly and time-consuming to repair. Waterproofing can help to prevent these issues from occurring in the first place.

There are many different types of waterproofing, and each one has its own advantages and disadvantages. Liquid-applied membranes are typically the most affordable, and they can be applied in a variety of ways, including brushing or rolling on the surface of the structure. Bituminous materials are another popular choice for waterproofing, and they can be made of black tar-like substances or polymers.

Some waterproofing systems are also based on cement, which makes them more durable than other types of membranes. However, this method is not suitable for all structures, and it requires the surface to be thoroughly prepared before applying the waterproofing layer. A drainage system is also necessary to prevent water puddles from forming.

In addition to the surface waterproofing, it’s important to consider how the structure will be used in the future. For example, if the building will be used for residential or commercial purposes, it’s vital to use waterproof materials that can withstand foot traffic and heavy equipment. There are many options available for concrete waterproofing, such as RD-Elastometal and RD-Sunguard.

Waterproofing can be a complicated process, but it’s worth the investment to protect your building from the elements. Waterproofing can help to extend the life of your building, as well as reduce energy costs. It’s crucial to choose the right waterproofing system for your structure, and consult a professional to ensure that you get the best results.

Fireproof

Roofing is the largest component of your house, and it is at risk from severe weather hazards like fire. The good news is that there are now roofing materials designed to provide Class A fire safe protection.

There is no roofing material that is completely fireproof, as even metal can be damaged by high heat, but there are products that will give you a much safer home. A roof that is not fire resistant is at risk for damage from flames, and may become a fuel source for the flames or burn through to the structural frame of the building. This can cause serious injuries or property damage.

Non-metallic roofing materials like wood shingles, asphalt shingles, or thatch can ignite and burn when exposed to flames and high temperatures, destroying the underlying structure. They also tend to have lower melting points than metal, which can cause them to soften and melt, leaving the underlying structure vulnerable. Fortunately, most roofing materials that are not made of metal can be protected with a fire-resistant coating.

These coatings can be applied to a variety of roofing materials, including shingles, clay tiles, and concrete slabs. Clay tiles have been used as a roofing material for centuries in warm climates, and they are highly effective when it comes to fire resistance. They can be found in a variety of styles and colors to match any home, and they are very durable, as well.

Another popular option for roofing is synthetic shingles, which can be molded to look exactly like traditional wooden shingles without the vulnerability to fire that they have. They are a good choice for California homes, which are often impacted by wildfires and drought conditions. A fire-resistant coating also helps protect against water penetration, which can lead to damage or leaks. In addition, the coatings can help reduce pest presence on the roof, which is a common problem in these areas. The coatings can also help extend the life of the roof, making it last longer and protect it from harsh weather conditions.

Windproof

Wind is a real threat to roofs, especially in areas that experience harsh weather conditions like hurricanes. Even without a storm, strong winds can cause damage to the structure of a home by tearing off or breaking shingles and tiles and blowing them around. According to a study by Traveler’s Insurance, about 25 percent of all homeowner’s claims between 2009 and 2015 were due to wind damage.

The best way to protect your roof against high wind is to choose a tough and durable roofing material, such as metal or standing seam metal. These materials have excellent resistance to wind uplift, which is the primary cause of broken or displaced shingles and tiles. This helps the roof stay securely in place and avoids costly tile repairs.

In addition to choosing a strong roofing material, you also need to take care of the existing roof installation and other components on your roof. Things like vents, solar panels, satellite dishes and HVAC equipment can disrupt the aerodynamics of a roof and increase the risk of damage from strong winds. Using the right fasteners and avoiding loose or exposed items can help reduce the likelihood of these disruptions.

Some roofing materials are rated for their resistance to wind, such as shingle or metal roofs that have passed special tests through Underwriters Laboratories. These roofs are often marked with a class rating and UL code to show that they’re able to stand up to strong winds.

Other roofing materials are more susceptible to wind damage and need to be reinforced in areas where stronger winds can put pressure on them. These areas include the ridge of the roof, corners and eaves. These areas are usually the first places to sustain wind damage and should be reinforced with extra roofing clips and fasteners.

If you live in an area prone to hurricanes and other severe storms, it’s important to plan ahead and make sure that your roof is ready for strong winds. This means picking the right materials, planning the design just right and doing regular check-ins to make sure that everything is in good shape.

Easy to Install

The installation process is simple, especially if you choose rolled roofing. This type of roof is the least expensive and requires little in terms of materials, such as rolls of roofing and 11-gauge roofing nails. It’s also very easy to work with, making it an ideal choice for DIY projects.

Before starting your project, make sure to clean the roof thoroughly. This will remove any dirt, debris, and other contaminants from the surface of your roof. This will help ensure a smooth, watertight finish.

You should also wear gloves when working on the roof. Additionally, you’ll need a ladder and a pair of safety goggles. It’s also a good idea to have a small pry bar and screwdriver on hand in case you encounter any stubborn shingles during the process.

Roofing Materials

A roof protects a building from rain, snow, sunlight, and extreme temperatures. Roofing is an exciting and challenging form of construction that requires a skilled team.

Communicating regularly with clients throughout their roofing project helps them feel informed and confident in your expertise. Whether clarifying details, communicating delays, or offering reassurance, timely communication promotes transparency and builds trust.

There are many roofing materials available to homeowners. The best choice will depend on several factors including cost, style and durability. The material should also be suited to the climate in which the roof will be installed.

Asphalt shingles are popular due to their low price and good performance in most conditions. They are the most common roofing material and come in a wide variety of colors and styles. Other options include wood shingles and shakes, clay tiles, metal, solar roofing and slate.

Slate is a natural roofing material with an elegant, layered look that adds to the beauty of classic and historic homes. It is also durable, fire-resistant and highly resistant to rot and insects. It can last up to 60 years, depending on the environment. Slate is heavy and requires a special framing system. It is also expensive and a specialist must install it.

Clay tile roofing is another natural option that combines beauty and durability. It is made of molded and fired clay that can be shaped into flat or wavy shingles. This type of roofing can last up to one century and adds a beautiful aesthetic to certain home designs. It is also fire-resistant and durable against extreme weather, including high winds, salty air and hail damage.

Flat roofs are difficult to waterproof, so it is important to choose the right roofing material. Many homeowners choose a single-membrane roof treatment such as EPDM, rubber or PVC. This is a more durable roofing material that holds up against foot traffic, provides excellent UV protection and has good fire ratings. It can be a more economical choice than other types of roofing, but it may not provide as much curb appeal or enhance the resale value of a home.

For those looking for a durable, low-cost alternative to shingle roofs, metal roofing is a good option. It is available in a variety of colors and styles, including standing seam and corrugated metal. It is ideal for flat or low-slope roofs and is available in a variety of thicknesses. It is also fire-resistant and can withstand extreme weather, including high winds and freezing temperatures.

Roofing Installation

A roof is a structure that covers the top of a building and protects against rain, snow, sunlight, wind, and extreme temperatures. A roof can be constructed from a variety of materials and may have a flat or pitched surface. Some common roofing materials include asphalt shingles, metal panels, and slate tiles. The process of installing or repairing a roof includes the following steps:

Before beginning any work on your roof, the crew will set up protective measures on your property. Tarps will be placed over anything that cannot be protected, such as your deck or pool, and wooden boards will cover the ground near the house to prevent shingle debris from falling onto and damaging your landscaping. The crew will also cover your attic and move any furniture or other items out of the way.

Your roof sheathing is covered with a layer of underlayment, which acts as a waterproof barrier between the sheathing and your new roofing material. The contractor will nail the underlayment into place, with rows of overlapping material being secured in a pattern that ascends from the bottom edge of your roof to the ridge. A drip edge is then installed, which is a strip of metal that directs water away from the edges of your roof.

Depending on your roofing type, the next layer will be your chosen roofing material. The roofers will start at the eaves and work their way up, carefully laying each shingle into place. They will overlap each row by at least six inches and secure them with nails that are close together along the edge of the shingle and spread out farther apart as they move to the center. The shingle rows will be sealed with roofing caulk, and the edges of your roof will be covered with a flashing to prevent moisture from seeping into your home.

Roofing Repair

In addition to fixing leaks and repairing or replacing shingles, roofers often repair or replace flashing (metal that’s bent to fit the application) around chimneys, wood stove pipes, roof valleys, along hip roof lines, and in certain other leak-prone areas. To do so, the roofer will typically remove the old flashing and use it as a template to cut and bend a new piece of flashing to fit the damaged area. Then, they’ll either nail it in place or, if nails aren’t appropriate, use roofing cement to encase the flashing. Depending on the damage, other tools that may be used include shears for cutting shingles and a pry bar for removing or leveraging sheathing, shingle edges, and flashing.

After all repairs are made, the roofer will complete a walk-through with you to show you the results and ensure that there are no loose nails or metal pieces left behind.

Roofing Maintenance

A roof should be inspected on a regular basis to address minor problems before they become major issues. A checklist is a useful tool for roofing professionals to use during inspections and document the condition of a roof.

It’s important to inspect the flashings on a roof, as a majority of leaks originate there. Detailed inspections should be conducted at skylights, perimeters, walls, penetrations, equipment curbs, and drains.

Down spouts should be cleared of debris so that water can flow properly off the roof and away from the home. Keeping downspouts clear is essential during heavy rains to prevent leaking and flooding.

Check for accumulated dirt, leaves, and other debris that can clog drains, damage roof surfaces, and cause structural elements to deteriorate prematurely. Fallen tree limbs can also damage roof membranes and elements. It’s a good idea to have trees trimmed regularly around your home.

Ensure that all employees involved in the maintenance program are background checked. This is especially important if the building contains electrical, harmful chemicals or hot equipment that can be dangerous for personnel working on the rooftop.

Materials

Homeowners today have a wide range of roofing materials to choose from with varying lifespans and prices. Choosing a durable material that adds value to your home while ensuring longevity and weather resistance is crucial.

The most popular type of roof is the asphalt shingle, which provides an attractive appearance and a great value. It also offers good durability, able to withstand most weather conditions and elements.

Another popular choice is the tile roof, made of earthen clays molded into interlocking shapes and fired for hardness. Its durability makes it an ideal choice for hot climates and areas where salt air is prevalent, and it adds a high level of luxury to a home’s exterior.

A more expensive but extremely long-lasting option is the slate roof, which is a natural roofing material that offers a unique and elegant look to any home. Slate is available in a variety of colors and hues, and it is known for its strength and fire resistance. It is also a sound investment, as it can last for more than 100 years with the right conditions and maintenance.

Those looking for a more affordable roof should consider membranes such as Thermoplastic Polyolefin (TPO) or Polyvinyl Chloride (PVC). These membranes are flexible, making them resistant to punctures and tears. They are also easy to install and can withstand most weather types and conditions. Moreover, they are heat-resistant, which can lower your energy costs.

Rolled roofing is another option for low-slope roofs such as those on outbuildings like sheds or garages. It consists of large rolls of mineral-impregnated and asphalt-impregnated material that is topped with mineral granules. It is inexpensive and requires little maintenance, but it doesn’t offer much in the way of aesthetics.

Composite shingles are one of the newer roofing materials on the market that provide the look of traditional roofing tiles but at a more economical price point. They have the highest impact and fire ratings and can last up to 30 years. In addition, they are very easy to maintain and carry some of the best warranties in the industry.
