Roof Replacement Case Studies: Roof Inspection Shows Damage From Lichen and Algae Growth on Shingles
This home in Ellington Connecticut had a problem with moss and lichen growth on their shingles. While plant growth on a roofing system causes damage to the shingles many cleaning methods can cause even more damage. These homeowners had their roof power washed, while this does remove moss, algae and lichen it also removes more.
Many physical methods of plant removal also dislodge protective granules from the shingle surface as shown in the picture below. This allows water to begin to wear away the mat of the shingle that is below the granules. The best bet to prevent plant growth and protect the home is by using a shingle with an algae and stain resistance warranty.
