Algae growth on roof shingles is very common issue here in the NW, Portland OR, Vancouver WA and surrounding areas. The good news is it does not affect the function and performance of the shingle. Gloeocapsa as known as algae is only an aesthetic problem. Lucky roof shingles now have algae resistant technology to help slow down the process of growth. Roofing manufacturers like IKO, Malarkey, Owens Corning, GAF, CertainTeed, Tamko cover this in their limited lifetime warranties.
Another important factor to think about when installing a new roof is the color. Lighter colors will show more stains and algae. The darker colors hide them. If you are looking for a new roof replacement, contact us for a free estimate and more information on roof shingles for your home.
