The Benefits and Potential Problems of Metal Roofing

Roofer West Chester PA provides optimum weather protection, and homeowners choose them more often. Whether replacing an existing shingle roof or adding a contemporary style, homeowners and building owners must have all the information they need to make the right decision. One of the most common concerns is cost. Another is the complexity of installation.


Metal roofs are highly durable, lasting decades and often outlasting traditional roofing materials. They also require minimal maintenance, saving time and money for property owners. However, like any roofing, there are some potential problems with metal that property owners should be aware of.

Depending on the climate, metal can be subject to certain issues. For example, homes and buildings in coastal areas need to choose a metal roof compatible with salt air. Otherwise, the roof could experience premature corrosion. A reputable contractor can help you determine which metal is best suited for your location.

Another issue that can affect metal roofing is fading and chalking. This occurs when the paint resin breaks down due to exposure to UV rays and other environmental factors. This causes a white residue on the roof and uneven fading of the paint color. While these issues are common, they can be minimized by using high-quality paints and having routine inspections conducted by a professional.

The majority of leaks in metal roofs are caused by poor installation, but they can also be caused by thermal expansion and contraction and improper flashing details. When these issues go unrecognized or unaddressed, they can lead to water intrusion, structural damage, and mold and fungus growth.

A reputable metal roofing company should be able to address these issues by following the manufacturer’s installation guidelines and providing quality flashing and detailing. Additionally, regular inspections should be conducted to identify any leaks or other issues that need to be addressed immediately.

In addition to these issues, it is important to be aware that metal roofs can become damaged by pea-sized or even dime-sized hail. While steel is generally better than asphalt shingles in this area, it’s still a good idea to have homeowner’s insurance with adequate coverage for hail damage, especially if you live in an area that experiences frequent large hailstorms. This will ensure that any damage to your metal roof is covered by insurance and won’t lead to costly repairs or a complete replacement.

When properly installed, metal roofs reflect the sun’s heat instead of absorbing it. This reduces reliance on air conditioning, which helps lower energy costs. Additionally, the roofs help to lower carbon emissions. With the rise of gas prices and environmental consciousness, many homeowners are looking for ways to improve their homes’ energy efficiency. A metal roof offers the potential for energy savings and eco-friendliness that aren’t available with other roofing materials such as asphalt shingles.

One of the most common problems that can occur with a metal roof is corrosion caused by dissimilar metals. This can be caused by excessive contact with chemically contaminated water, trapped moisture or galvanic reaction between dissimilar metals. In addition, the corrosion may be accelerated by extreme weather conditions.

To prevent corrosion, it’s important to use galvanized fasteners. It’s also important to periodically inspect the roof and re-seal any areas that are susceptible to leaks. This will help to extend the life of the metal roof.

Leaks can result from incorrect installation or a lack of maintenance. If a leak occurs, it’s important to repair it immediately. If the leak is not repaired, it can lead to structural damage and mold or mildew growth inside the home or building.

Other common problems include thermal movement, which can shift the panels and cause loose fasteners or gaps. It’s important to choose a contractor who understands the dynamics of metal roofing and will install it correctly to ensure a long-lasting roof.

Some consumers may be drawn to metal roofs because they offer a large selection of colors and styles. However, it’s important to consider the overall construction and budget of the project. If a homeowner wants a high-end metal roof, they will likely have to pay more for it than if they chose a standard asphalt shingle roof.

Choosing a metal roof can provide significant benefits for any home or business owner. They can last for 40 to 70 years and are more durable than other roofing materials such as asphalt shingles. Metal roofs can also help to reduce energy costs, lower carbon emissions and increase comfort for residents and employees.

For many homeowners, the main benefit of metal roofing is not related to performance or longevity but to how it looks. While many metal roofs have an industrial look to them, the wide variety of styles and color options provide a design aesthetic that matches any home style.

Aesthetically, there are few roofing materials that compare to the beauty of a well-maintained metal roof. Many metal roofs are designed to meet the aesthetic needs of any architectural style, from the classic appeal of corrugated roofing to the clean lines of standing seam panels. Additionally, several types of shingle profiles are available to give metal roofs the appearance of traditional asphalt roofs without the deterioration and maintenance costs.

Standing seam metal roofs offer clean, modern lines and superior weather protection that can last for decades. The raised, interlocking seams eliminate exposed screws and protect the interior of the structure. The textured finish of the panels adds depth and a visual interest to any building.

Other metal roofing systems also provide a diverse range of visuals. Corrugated panels can be shaped into wavy folds or alternating furrows and ridges to create a unique design feature for a roof. Other profiles include smooth panels with a glossy, weathered finish or textured surfaces that replicate the look of clay tiles or slate. These systems can be layered with rubberized underlayment to reduce noise and improve insulation.

In addition to profile diversity, metal roofs can be painted with a wide range of colors. From earthy tones and neutral hues to vibrant shades, the palette offers an aesthetic that compliments any architectural design. Textured finishes and paint coatings provide further customization, giving building owners a canvas to express their individuality.

In contrast, other roofing materials lose their beauty over time, becoming streaked, stained and damaged. A well-maintained metal roof, however, retains its aesthetics, enhancing the home’s appearance and boosting its value. For these reasons, homeowners understandably choose to invest in a quality metal roof that will not only serve its functional life but also enhance the beauty of their home for decades to come.

Metal roofing offers homeowners an attractive alternative to shingle roofs, but it’s not an easy project for a novice. You’ll need a lot of tools and materials to get the job done properly. If you’re not familiar with metal, it’s best to hire a professional roofing contractor.

When choosing a roofing contractor, ask about their experience and what kinds of projects they’ve worked on in the past. A reputable contractor will also be able to answer your questions and provide references from other happy clients.

Installing a metal roof requires special attention to detail, as many of the panels are larger than their asphalt shingle counterparts. In addition, the fasteners must be correctly positioned and secured to avoid leaking or structural damage. It’s important to use quality screws and to make sure the neoprene washers are properly seated.

Depending on the type of metal you choose, the installation process can be quite simple or challenging. For example, through-fastened standing seam systems are easier to install than mechanical lock or snap-lock styles. Snip-and-tuck or traditional stone-coated steel systems are also more manageable than standing seams, but require specialized roofers’ skills.

If you’re considering a DIY project, check local laws and regulations to determine whether or not you need a permit to work on your home. If you do, be prepared to submit a detailed plan for the project to your city or town’s building department.

Before you start working on the roof, remove any debris or plant material from the surface. If your metal is unpainted, you should also take care to keep it clean.

A metal roof can last a long time, but it can become vulnerable to corrosion over time if it isn’t treated with care and attention. If you notice rust spots or other signs of corrosion, bring them to your roofer’s attention right away.

A reputable metal roofing company will address these problems before they cause any permanent damage. They will test the integrity of your metal roof with a moisture meter to ensure that you’re protected from leaks and other problems. They’ll also provide you with a written warranty that protects you from future issues.
