Call A Residential Roofer To Identify Black Streaks And Spots On Your Roof So Repairs Can Be Done
If it looks like your roof is turning green or black, or if it has ugly black streaks on it, call a residential roofer to see what's growing on your shingles. Your roof could have algae, moss, or mold. Once you learn what the problem is, you and your roofer can figure out a way to deal with it. Here are some ways to eliminate ugly growths on your roof.
Wash Algae Off
Algae isn't as destructive as other types of growth. Your roofer may discuss the benefits of washing the algae off against the risk of harming your shingles by washing them. If you don't like the way algae makes your roof look, then washing your roof with a solution that kills algae might be necessary. However, the algae might grow back unless you trim back trees to allow more sun on your roof.
Your roofer might also suggest placing metal strips along the top of your roof that keep algae from coming back. Strips made of zinc are often used since bits of zinc are washed down the roof along with rain, and the minuscule amount of zinc can keep algae from growing on your roof.
Kill And Remove Moss
Moss is a little more dangerous than algae because it can lift shingles. Plus, it holds moisture against the roof, so moss should be removed. That might be done manually with a brush after killing the moss with a bleach or vinegar solution. Care should be taken not to damage the shingles.
It's good to remove moss before it spreads and gets out of control. It's also a good idea to let a residential roofer check your shingles and the deck for water damage so repairs can be done if they're needed.
Kill, Seal, Or Remove Mold
Mold is probably the most dangerous growth to find on your roof. Mold can spread under the shingles and get inside your house. Mold indicates a moisture problem. The moisture can cause the mold to flourish. Since mold can destroy wood and other building materials, your roof might start to rot due to mold. Your family might even experience health problems due to mold spores circulating in your home from the roof.
The roofer might replace moldy parts of the roof, depending on how much the mold has spread. You might need to replace your entire roof if there is enough damage to the deck and rafters. In addition to having work done on your roof due to mold, you might also need mold remediation in your attic or living space. Mold is something you don't want on your roof, so if you see black streaks or spots, call a residential roofer near you to identify the markings and to see how badly your roof has been damaged.
