Why would you need a roof replacement in Fall River? Roofs can last for quite a while. Asphalt roofs can last up to 20 years, while metal roofs can last nearly 100 years. Despite the longevity of roofs, there may be hidden problems with your roof that may have compromised it, causing you to need a roof replacement.
For instance, asphalt roofs may develop mold or lichen on them, which can compromise the roof. These microorganisms grow on roofs, mainly when there is moisture present, and they can shoot roots through the shingles into the roof sheathing. As they grow, they can loosen shingles allowing for moisture to get between the sheathing and the shingle, resulting in damage to the plywood and leaking.
Another threat to shingles is black algae which are also known as Gloeocapsa magma. This looks like a black stain on the roof. However, it is a microorganism that grows and feeds on asphalt roofs, removing the UV granules which help protect the shingles and deflect the sun. Once these are gone, the shingles can become brittle and break, exposing the decking to moisture and eventually leading to leaks.
When this happens on a massive scale, you will have to have your entire roof replaced. Roof replacement can involve simply replacing the roofing materials. Or, it can include replacing the roof decking, the roofing materials, the roof flashing, gutters, and more, depending on how much damage is present.
