With an average of heavy rainfall (at least one inch) for 17 days a year and an annual rainfall of almost 50 inches, why wouldn’t that keep your roof clean?

That’s a good question.

The answer is that rain is part of the reason your roof needs to be cleaned. Rain gets into crevices, under shingles, into weak spots, into the flashing and gutters. Once moisture is there, it causes mold, mildew, moss, and algae growth that can cause damage to your roof’s materials. This leads to leaks and can destroy the shingles’ UV protection, shortening your roof’s life by as much as 10 years. The damage can be further complicated by leaves, branches, birds’ nests, whatever else that blows onto the roof and disintegrats into the crevices.

Royal Crown Roofing uses a process called soft wash roof cleaning that cleans out all of these destructive roof irritants without doing damage to any of the protective elements in the roofing materials—unlike the high-pressure power washing technique some companies use, which can also wash away some of the essential layers that protect the roof.

Your roof does a good job all year long protecting your home, pets, belongings, and family. You need to do it a favor and protect it with an annual soft washing that will extend its life, keep it looking good, and save you money on costly repairs.
