Made primarily of steel and aluminum, some brands also use alloys and copper. While aluminum is less durable than steel, it will not corrode as quickly. They are lightweight and their reflection of the sun’s rays helps the homeowner reduce their energy bills. In addition, this type of roofing material is fire-resistant, durable, and much lighter than many other roofing materials.
Metal roofs are known to be long-lasting with most warranties providing a 40-year guarantee. This makes it an excellent choice for those who desire a roof that is virtually trouble-free. With proper insulation, it can offer a significant reduction in energy costs both in the summer and winter.
TYPES OF METAL ROOFING
Aluminum is lightweight, corrosion-resistant, and durable. It is available in a number of different roofing systems including panels, shakes, shingle, tile, or slate models. It is rust-resistant and is ideal in areas with heavy storms. Since it is pre-painted nothing needs to be done after installation. It contains approximately 90 to 95% of recycled materials. It is more expensive than steel.
Galvalume Steel is a carbon/iron steel coated base with a mixture of zinc and aluminum. It is sometimes installed unpainted because it is more resistant to corrosion than galvanized steel.
Galvanized Steel is rust-prone and must be coated on both sides with another alloy or metal. This metal is treated with a hot-dip process. It can also be subjected to a process called electroplating. This is not recommended for people who live in coastal areas as the salt spray will speed up corrosion. It has a shorter life span than other metal roofing materials.
Copper is a beautiful roofing material but is much more expensive than the other three metal roofs available. On a regular home, it is usually used for accents where a special style is desired.
Naturally, as with all roofs, repairs are sometimes needed. Rust and dents are the most common problems with a metal roof. Unfortunately, if left untreated rust can soon eat a hole in the roof and allow water to seep into the attic. This can result in mildew, mold, structural damage, and other problems.
This is especially true of metal shingle, tile, shake, and slate installations. This makes it imperative to have a contractor who is well acquainted with metal roofing construction and who has the expertise to make the proper repairs quickly and efficiently. This is the time to call a metal roof repair contractor.
Always make sure the roofing contractor you hire is qualified, insured, licensed, and has a good reputation in the community. You can always check the Better Business site to see if they are in good standing. They should be able to provide references, if required, and offer a free estimate on any repairs to your metal roof.
