Spray and Walk Away

As harmless as it looks, moss can be very damaging not only to your roof, but also to the rest of your home. There is no doubt that extensive moss on a roof can damage the roof by growing under and loosening the shingles, trapping moisture against roofing materials and causing leaks. Moss doesn’t need much to grow; shade, moisture and a temperature between 32 and 70 degrees. By not having a root system, moss doesn’t need soil to grow—making your roof an ideal location.
