Debunking Myths Surrounding Roof Cleaning

before and after roof cleaningRoof cleaning may seem like a simple process, but there’s more to it than you might expect. There’s also more to common debris found on the roof. Learn the real truth behind roof cleaning myths so you can take proper care of your home’s roofing system.

MYTH: Dirt and Environmental Pollutants Cause Staining

It seems straightforward, right? If your roof appears stained, something must have made it dirty.

While dirt and airborne pollutants do discolor roofs, they are not the major source of staining. That’s reserved for moss and algae — which are more difficult to remove than a simple speck of dirt.

MYTH: Moss and algae are cosmetic problems

Yes, moss and algae look unsightly. Yet it’s not their ugly appearance that should concern you, it’s their potential for destruction.

Moss and algae consume the limestone in asphalt shingles, which gives the shingles their strength. This robs the shingles of their natural lifespan, so you need a new roof faster than you otherwise would.

Moss and algae also reproduce quickly — making this a problem you can’t ignore.

MYTH: It’s easy to clean a roof

We hear this all the time! In theory, anyone can clean their own roof. Before you climb up there, however, ask yourself if you know how to properly use the right chemicals to banish moss and algae. Assess your comfort with climbing on a roof all day and your knowledge of how to do it safety.

If you’re having second thoughts, contact a professional roofer who knows how to do the job correctly.

MYTH: Power washers work well for cleaning roofs

If you’re having second thoughts about using chemicals or climbing on the roofs, you might think a pressure washer would be a good solution. A strong blast of water can dislodge moss, right?

That’s true, however … the power washer can also dislodge granules from your asphalt shingles, which shortens their lifespan. You could do more harm than good by using a power washer to clean the roof.
