Are you planning to spend your weekend blasting away the grime on your home exterior? You might want to pause before pointing that high-pressure wand at your roof.
Many homeowners think they are doing a great thing by giving their shingles a deep clean. It makes sense on paper. You wash your car, driveway and siding to keep them looking fresh. Why not your roof? The truth is that power washing your roof is one of the quickest ways to destroy it. What starts as a simple weekend chore can easily spiral into a massive headache and a $10,000 replacement bill.
The Hidden Danger of High-Pressure Water
Have you ever looked closely at your asphalt shingles? They are coated in tiny granules. These granules give your roof its color, but they also serve a much more important purpose. They protect the delicate asphalt beneath from harsh UV rays, heavy rain and severe weather.
When you hit those shingles with high-pressure water, you strip those protective granules right off. Without them, your shingles will bake in the sun and quickly become brittle. They will eventually crack, curl and fail. Suddenly, your roof can no longer keep out the rain. Water seeps into your decking, ruins your insulation and damages your ceiling.
Is a temporary clean look worth destroying your home defense system?
Even Those Ugly Streaks?
So what exactly are those ugly black streaks ruining your curb appeal? Most people assume it is just dirt or soot. It is actually a type of black algae called Gloeocapsa magma.
This algae feeds on the limestone filler used in modern asphalt shingles. As it eats and multiplies, it leaves behind a dark stain. It looks terrible and can slightly reduce the lifespan of your roof over time. However, blasting the algae away with high pressure causes instant, catastrophic damage. You might remove the dark streaks, but you will take half your roof with it.
The Soft Wash Solution
How do you get rid of the algae without ruining your property? How can you keep your roof looking fresh? The answer is a professional technique called a soft wash.
Soft washing uses specialized cleaning solutions applied at a very low pressure. The pressure is comparable to what comes out of a standard garden hose. Instead of relying on brute force to blast away the stains, the cleaning solution does all the heavy lifting. It safely kills the algae, breaks down the dirt and restores the original color of your shingles.
Your roof gets entirely clean, and those vital granules stay exactly where they belong.
