Cedar Shake Roof and Cedar Siding Cleaning in Evanston Cook County

Does your red cedar, cedar shake roof or cedar siding need to be cleaned? What color do you see – dark grey, black, brown, green, yellow? If you see any of these colors on your cedar shake roof or cedar siding, please take notice.

These colors are actually signs of infestations of mold, moss, algae, mildew, lichen, and fungus. We see this a lot in the north and west suburbs of Chicago such as in Evanston and Schaumburg in Cook County.  A professional roof cleaner will pay particular attention to any signs of infestation. These organisms spread across the cedar surface and if left untreated will cause the shingles to deteriorate.

Fungus commonly causes the wood to feel moist, soft, spongy, or stringy. It is dangerous because it simultaneously breaks down all the major wood components in your shingles.   This causes the shingle to gradually degrade to a spongy and stringy texture, causing it to weaken, shrink, break, and collapse.
