Roof Cleaning Truth

There is a key misunderstanding when it comes to asphalt shingle roof cleaning. Most people assume that you cannot have your shingles cleaned without causing harm to them. Over 50% of roofs replaced in the Midwest are replaced because of the way they appear, not because of their functionality. What does this mean? It means that when roof algae gathers on a roof and causes black streaks, half of the time the homeowner will call a roofing contractor, and without much contemplation, will have the roof replaced. You can also be certain that a roofing contractor isn’t going to talk themselves out of a sale by telling the homeowner the roof only needs cleaned. Moreover, some roofing contractors perhaps don’t apprehend that roofs can be cleaned without causing harm.

Damage is done to the roof only when too much pressure is applied to the shingles to attempt to blast the algae off the roof. On no account should you use, or allow a contractor to use, a pressure washer to clean your roof. Doing so will diminish the longevity of the shingles by blowing the shingle granules off which are there to shield the shingle. The chief shingle manufacturers have guidelines and suggestions for cleaning roof algae off of asphalt shingles. This technique includes the proper cleaners applied with low pressure followed by a light rinsing. No more than garden hose pressure is ever put on to the roof. This is an effective way to destroy roof algae and restore your roofs appearance without causing harm to the shingles. Correct roof cleaning can save you thousands of dollars by not having to replace shingles that only need cleaned.
