Roof Cleaning questions, answered by experts

Soft washing chemicals typically consist of a mix of sodium hypochlorite (or a chemical component of bleach) and water. While sodium hypochlorite and bleach are often thought to be the same thing, there is one small but key difference between the two: sodium hypochlorite comes in powdered rather than liquid form, which means that it’s also more concentrated and more effective from less product overall.

You should not clean roof shingles if the roof has damage like missing shingles or low spots where water may accumulate. You should focus on repairing the roof before any cleaning process occurs. If you notice roof damage as you’re climbing on the roof to clean it, stop immediately. Call a roofing pro to make repairs. Cleaning a roof that has damage could lead to pooling water or water damage to the roof decking. The roof cleaning process removes mold and mildew, making the roof look better. It is not going to fix physical damage, though.

Roof cleaning can damage shingles if it’s done incorrectly—like with a high-power power washer—but it likely won’t damage your roof if you pay to have an expert do the work. A professional roof cleaner will use a gentle cleaning solution and a cleaning method that matches your roof material to ensure the process doesn’t damage the roof. Some homeowners worry that roof cleaning will shorten the life of their roof by removing shingle particles or protective coatings, but it often extends roof life by removing plants that cause damage and improves your home’s curb appeal simultaneously.

The best time to clean the outside of your house is during your outdoor spring cleaning. Wait until late spring, after the wave of pollen is done coating your home. You can also wash your house in late fall–before the first freeze–to remove leaves and branches from the gutters.

Even though you don’t look at your roof often, there are some telltale signs that you should have your roof professionally cleaned. It’s best to hire a professional roof cleaner as soon as you notice signs of wear and tear to preserve the essential feature’s longevity. Some indicators to look out for include:

  • Leaf buildup in gutters

  • Dirt and grime buildup

  • Moss or black algae growth

  • Dirt buildup under shingles

  • Shifting roof shingles

  • Plant growth
