Sometimes when you see black on asphalt shingle roofs, you may think the roof is losing its granular surface and the black asphalt is being uncovered.

Not so!

In most cases, its merely a mildew fungus problem and the roof simply needs a proper cleaning. But if nothing is done the roofing will deteriorate earlier than the manufacturer's life expectancy.

The safest and most effective method of roof cleaning is to use a roof cleaning company that does not use pressure washers and does not walk on your roof. This is achieved by the distribution of cleaning agents on the roof that dissolves the mildew and fungus...leaving your roof looking as good as new. Remember, United Roof Cleaning will never use a pressure washer on your roof.

Say NO to high pressure!

Pressure washing requires walking on virtually every foot of your roof inevitably causing cracked tiles. This method of roof cleaning can also dislodge the cement on the ridges and valleys that hold the tiles together and cause serious damage. High pressure can also dislodge or loosen the roofing granules in shingles causing serious damage to roofing materials. Pressure washing may even void the manufacturer's warrantee.
