What To Expect With Maintenance And Repairs For Three Common Types Of Residential Roofing
Posted on: 6 May 2021
If it's time for a roof replacement, you may be comparing metal, clay tile, and asphalt shingles since they are three common types of residential roofing. Each is priced differently and has its own benefits. When you're making your decision, it helps to know what kind of maintenance and repairs each type of roofing may need. Here's an overview of what to expect with these three types of roofing materials.
Asphalt Shingles
This is the most affordable roofing, and it may need the most care. Asphalt shingles come in different thicknesses. The thinnest style is the least durable, but they're also the most popular since they cost the least. Shingles might be lifted by wind, cracked or dented by hail, and damaged by UV exposure.
If you're handy, you might repair or replace a few shingles on your own. If not, you'll need to have a roofer make repairs to prevent a roof leak. Asphalt shingles can also curl if the attic ventilation is poor due to excess heat. They can also be damaged by moss growth or tree branches that sway in the wind. While the shingles may need the most care, they can last for many years if they're maintained well.
Metal
Metal roofing lasts much longer than asphalt shingles, and this material needs less care. However, the roof still needs to be checked for signs of damage, and prompt repairs are needed to prevent leaks. If you opt for a metal roof with exposed screws and washers, the screws might back out over time and the washers might crack and let rain leak in. For that reason, a metal roof should be checked periodically to make sure the screws and washers are in good shape.
Rust is also a potential problem with a metal roof. However, since the roof is coated, rust isn't usually a concern unless something scratches through the coating down to the metal.
Clay Tile
Clay tile roofing also has a long life. That said, the tiles have the potential to crack or chip off when struck by hail or tree branches, so the roof should be inspected regularly. The tiles can also be damaged if stepped on wrong, so you'll want to be careful about climbing around on the roof.
Clay tiles can develop dark discoloration due to algae. The algae may not hurt the roof, but this residue can leave ugly streaks that you'll want to have removed. Moss also grows on tile roofs under the right conditions. Moss can lead to a roof leak since it's a plant with roots that spreads underneath the tiles. Therefore, moss should be removed to prevent damage to the roof.
