Algae affect many rooftops across the country. Most observers think it’s mold or mildew. Meanwhile, moss is usually present on north facing roof planes that don’t get exposed to enough direct sunlight and hold more dampness longer than planes that face south.
No, you don’t need drastic measures such as roof repair, to deal with roof stains from moss and algae. In this blog, we provide ways to prevent and discourage moss and algae growth.
Prevention is key
1. Trim tree branches hanging over your roof to allow the sunlight to hit it more directly. This will help prevent excess moisture from accumulating.
2. Regularly clear away debris accumulating on your roof. Use a leaf blower, and always blow the air down the roof to push the debris away.
3. Proper ventilation helps prevent moisture problems. A continuous and balanced flow of air removes humidity and draws in cool air to guard against moisture damage.
4. Keep your gutters clear of debris so that water can drain properly from the roof.
When replacing your roof, consider installing asphalt shingles that incorporate copper granules, as copper can slow down the aging process for asphalt.
Clean your roof with bleach and water to prevent the spreading visible algae and moss to nearby roofs.
These days, there are asphalt shingles available that use algae-resistance technology. Some roofing companies offer such products, and you can look no further than Expert Contracting Inc., a GAF Master Elite® Certified roofing contractor.
