Does your red cedar, cedar shake roof 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, please take notice.

These colors are actually signs of infestations of moss, algae, mildew, lichen, and fungus. We see quite a bit in the Springfield Metro.  A professional roof cleaner, like Shingle Brite, 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.

Brown rot fungus, commonly known as “dry rot,” presents itself as a black or dirt brown color. It commonly causes the wood to be dry and fragile, cracking across the grain. It is dangerous because it rapidly decays the cellulose and hemicellulose in the shingles, leaving a brown residue of lignin (the substance that holds the wood cells together). Brown rot is generally more serious than white rot, as it can quickly weaken the shingle before any visible signs are detected.   If left untreated, the shingles will easily crumble into cubes, and turn into a powder when crushed.

Moss, which is appears green and spongy retains constant moisture on the cedar shake. Furthermore, it does not permit the red cedar to breathe as it should. This causes the cedar shake wood to deteriorate rapidly.
