Have you been contacted by a contractor offering to pressure wash the roof of your Frisco or Carrollton home? Many of these contractors make claims that cleaning your roof extends its lifespan, which may sound like a good idea, but before you sign on the dotted line, we encourage you to keep reading this blog to find out why pressure washing and other roof cleaning services may leave you with a big problem.

The Problem with Power Washing

Pressure washing your roof presents a problem because shooting high-pressure water onto your roof damages your roof by taking off the protective asphalt granules off of your shingles. Without these protective asphalt granules, your roof loses its protection against the elements. Even the lowest setting of pressure on a pressure washer can cause the granules to come off, leaving your roof exposed to the sun, wind, and rain.

Power washing your roof is especially risky if your roof is ten years old or more, as it has probably already lost asphalt granules due to natural wear and tear.

Power washing not only stripes the protective layer off your roof, but it also can lift your shingles which breaks their seal and shingles become loose in a storm. When this happens, water can get underneath your shingles and your roof could develop a leak.

Do You Really Need to Clean Your Roof?

In some parts of the country, where there is a lot of rain and snow, it may be necessary to clean your roof to remove algae and moss that grow in shaded areas. However, in Frisco, Plano, and the rest of North Texas, cleaning your roof really isn’t all that necessary because the Texas sun usually keeps roofs dry and algae away.
