An Experienced

Roof Cleaning Company

At Ogilvie Roof Cleaning, we specialize in removing and killing the black algae, moss, and lichen that are destroying your roof and staining your siding. Algae, moss, and Lichen have firmly planted root systems which pull at your shingles, cause them to cup and eventually detach and fall off. A dirty roof can also lead to an algae outbreak which can cause leaks which will ultimately destroy the structural integrity of your roof. A shingles main purpose is to repel water. 

The more growth that is on your roof, the more water that is being held on the roof. This is more evident after a rain storm and the black streaks become overwhelming. One thing is for sure, a 30 year warrantied roof will not get close to its full life, if not cleaned and maintained. A dirty roof may void your warranty if a leak occurs, and may cause a problem with your insurance company. Don’t be stuck with the cost of replacement.
