Roof Algae

Roofs take the brunt of the elements, leaving them susceptible to mold and algae. While overgrowth can start out as an aesthetic issue, it can actually cause serious consequences if not taken care of. Luckily, both mold and algae issues can be fixed with a little advice from the roofing experts at New Jersey Siding & Windows, Inc.

How to Tell if Your Roof has Mold or Algae

Fungus usually affects homes located in damp, humid areas – especially those without a proper drainage system in place or homes with an old, damaged roof. If there are areas on the roof or the gutters where you see rain collecting and pooling, there’s a good chance fungus may spawn there. Algae gives the roof a black-green hue. If your roof has mold, on the other hand, you’ll see patches, streaks or stains of black, brown and dark green discoloration on the shingles. You may also notice an unpleasant odor.

The Problem with Fungus on the Roof

If not treated, the fungus can find its way inside your house and lead to costly repairs. This happens if there are any gaps or damaged areas on the roof, such as damaged or missing shingles and damaged flashing. Water can leak into the attic and bring the fungus with it. Once inside, the following problems can occur:

  • Ceilings have water marks, discoloration or dark spots
  • Visible mold
  • Musty smell in the attic
  • Water leaks
  • Rotting wood
  • Peeling paint and/or plaster
  • Problems with allergies and asthma

How to Get Rid of Algae and Mold on the Roof

So, what should you do if you have mold or algae on the roof? First, the roof needs to be thoroughly cleaned with a bleach solution to get rid of the fungus. After that, you’ll want to take steps to prevent it from coming back. Ultimately, if your roof is older (15+ year) it might be time to consider replacing it.
