Many people ask us how to keep their roof clean and free of debris. In this post, we’ll address some of the most common questions we encounter about roof cleaning. If you have questions or concerns, call us anytime for a roofing consultation.
Moss is generally harmless. You should only worry if your roof is sprouting fungi, algae or mold. These organisms can lead to a dangerous condition called roof rot.
Roof rot happens when you leave mildew, fungi or lichen growing on your roof. Over time, this plant growth can break through a weak spot in your roof. This leads to severe mold growth all over your roof and your home. That can be a dangerous condition that’s costly to fix.
If you live in a damp climate, you need to take steps to prevent roof rot.
The only way to be certain is with a professional roof inspection. You should have your roof checked twice a year to prevent roof rot and other problems. It’s also a good idea to have your roof checked after a major storm.
There are various methods you can use to clean debris, moss and algae from your roof. You can use a soft-bristled brush, a leaf blower or a hose with low pressure.
The first rule is to be careful. Roofing falls are the number one cause of construction-related deaths and injuries. Don’t do this while the roof is wet and slippery. Use sturdy shoes with gripping soles. If you’re at all worried about your safety, call a professional roofing contractor.
Power washing a roof is not a good idea. We don’t recommend power washing, jet washing or any other high-pressure cleaning method.
Most roofing materials won’t stand up to the high pressure of a power washer. Power washing can destroy the protective layer on top of the shingles. Spraying a power washer directly onto tiles can gouge holes in them.
Power washing can also damage roof elements like your fascia, windows and gables.
If you have unwanted plant life on your roof, it’s not going to come off with a simple hosing. There are only three ways to get rid of it:
This is one of the only times that we recommend power washing your roof. Follow these tips for the best results.
Note that power washing won’t work on a flat roof. It will leave puddles on your roof that just make the problem worse.
