How to Install Metal Roofing Over Existing Shingles

Metal Roofing Kalispell can be installed over existing shingles, which can save time and money. However, it’s important to determine whether the old roof needs removing first.

Roofing

Steel is much harder and fares better in hail storms than shingle roofs. It can also be insulated to reduce energy costs. It can even reflect radiant heat keeping the building cooler in summer.

If you’re planning to build a home or commercial property, or simply replace an existing roof, you want to choose a roofing material that will last. Metal roofing is an excellent choice, as it has a long lifespan and does not require extensive maintenance. Moreover, it is an energy-efficient option that can help save on utility costs and prevents mold and mildew growth.

While a metal roof may have a higher price tag than some other roofing materials, it pays off over time. It is also more durable than other types of roofs and can withstand severe weather conditions. Furthermore, it adds value to a building or home and can be recycled at the end of its lifecycle.

Durability is one of the primary reasons why more homeowners are choosing metal roofs over other roofing materials. Unlike shingle roofs, metal roofs are not susceptible to rot, mildew or insect infestation. They are also fire-resistant, which reduces the risk of damage from lightning strikes and wildfires. Additionally, metal roofs are more resistant to wind and can withstand hail better than other types of roofs.

The durability of a metal roof depends on the type of metal you select, the installation method, and how well it is maintained. Steel and aluminum roofs are the most common, but there are several other options available. For example, copper is a beautiful and durable metal that develops a natural patina over time and protects it from corrosion. Other metals such as zinc and galvanized steel are also highly durable and have a long lifespan.

It is important to have a properly installed metal roof that is built by a reputable company with experience and knowledge of the industry. If you’re considering a metal roof, research the companies in your area and find out what their reputation is. Look at reviews, investigate the company’s website and social media presence, and ask lots of questions before you make a decision. A good roofer will be happy to answer any of your questions. Also, make sure that the roofer is using high-quality fasteners and not cutting corners during the installation process. This can affect the durability of the metal roof and cause leaks or other problems later on.

Energy Efficiency

Compared to asphalt shingles, metal roofs have excellent thermal properties and can save homeowners energy costs. This is because metal is a very efficient roofing material, reflecting the sun’s heat instead of absorbing it. This reflectivity allows the inside of the building to remain cooler, reducing the amount of time air conditioning is used. This can also save money on utility bills and reduce carbon emissions.

Additionally, metal roofs seal the building more effectively than a typical shingled roof. This is because the seams of metal roofing fit together so tightly that the roof’s elements don’t leak into insulation, framing and drywall. In contrast, leaking shingles can soak into the materials in your home or commercial building, leading to damage and a lower quality of living or working space.

In addition, metal roofs are often quieter than other roofing materials, including asphalt shingles and concrete tiles. This is because the metal construction deflects sound waves. Some of today’s metal roofs, such as galvanized steel and aluminum, come in a wide range of colors, finishes and styles to complement any home or business.

The metals used for modern metal roofing are also more environmentally friendly than traditional shingle materials. They can be made from up to 95% recycled material, sourced from a variety of consumer, government and industrial sources. This makes metal roofing the most sustainable option for homes and businesses.

Another benefit of a metal roof is its longevity. A well-maintained metal roof can last 40 to 70 years, a life span that is significantly longer than the average lifespan of an asphalt shingle roof. This longevity is the top reason that most people choose a metal roof for their new build or re-roofing project.

It’s important to note that the longevity of a metal roof is dependent on the quality of the product and installation. It is important to research the different types of metal roofing available to make sure that you are getting the best product for your budget and needs. For example, some metal roofs are not designed for high hail damage. In addition, some of the lighter metals, such as zinc and copper, may develop a patina over time that is not attractive for everyone.

Weather Resistance

Whether you live in a region prone to hurricanes, tornadoes or other high-speed winds, metal roofs offer serious weather resistance. Because the panels interlock and fasten to the structure in multiple points, these roofs minimize where wind can penetrate. In fact, post-storm studies from Texas to New Jersey have found that standing seam metal roofs can withstand high winds and are more durable than shingle or tile roofs, particularly when properly designed and installed.

In addition to the durability of a metal roof, the reflective qualities help keep homes cooler and more energy efficient, reducing dependence on air conditioning systems. Additionally, metal roofs are naturally fire resistant and can withstand wildfires better than traditional shingles.

Because a metal roof is highly water resistant, it also prevents moisture absorption and can reduce damage to interior walls from mold, mildew and other fungal growth that can occur with shingle roofs. Many homeowners also find that they spend less time on maintenance because they do not have to deal with shingle tear off, repair and replacement.

Metal roofs are rust-resistant and come with a durable finish that can resist fading, peeling and staining. The Kynar coating helps slow the oxidation process that is caused by exposure to water and sunlight, making metal roofing a great option for coastal regions and areas with severe sun and humidity.

Most shingle roofs require regular replacement because they are susceptible to degradation from UV rays. In contrast, metal roofs are rust-resistant and have an unbroken, reflective surface that blocks harmful UV rays, extending the life of your roof. Because of their long lifespan and low maintenance requirements, metal roofs are considered more cost-effective than shingle roofs in the long term. They also have higher rated R-values and are easier to install in place of other construction materials. Additionally, most shingle tear-off waste ends up in landfills (up to 20 billion pounds per year), while metal roofing is recyclable. Depending on the type of metal used, most metal roofs contain 25-95% recycled content, making them more environmentally friendly than their shingle counterparts.

Maintenance

A metal roof is a long-term investment and needs regular maintenance to ensure that it will function properly for a long time. There are many benefits to maintaining your metal roof, including improving its appearance and increasing the value of your property.

Cleaning your metal roof is an important part of the maintenance process. This helps remove dirt, dust, grime, stains, mildew, algae, bird droppings and other elements that can damage your metal roofing panels. It also helps to improve the appearance, reflectivity, energy efficiency, surface corrosion and performance of your metal roof. Cleaning your metal roof can be done using water, a solvent cleaner or a soft brush and sponge. Alternatively, you can hire a professional roofing contractor to clean your roof for you.

Leaking roofs are a common problem that can lead to water damage inside your home, so it is crucial to inspect your roof regularly for leaks. Look for signs of leaking at the seams between panels and at any penetrations such as vents, chimneys and skylights. If the sealant is cracked or worn, it should be repaired immediately to prevent water damage.

Other areas to check for are loose screws and corroded washers. During your inspection, it is also a good idea to check the condition of your flashing, which are strips of metal that run along the edges and joints of your roof and cover any areas around penetrations like chimneys, vents and skylights. If the flashing is damaged, it can let in moisture that could damage or corrode the underlying metal roof panels and lead to leaks.

It is a good idea to consult with your roofing contractor or the roof material manufacturer for specific maintenance instructions. Different types of metal roofs have unique care requirements. For example, copper roofs often develop a natural patina that requires no maintenance, while steel roofs may require regular checks for rust. Following the manufacturer’s guidelines for your particular metal roof will help you to ensure that it performs at its best for a long time.
