Roof Cleaning for a Health Upgrade
Chelsea O'Donnell
If your roof has black, streaky stains or mold and moss growth, a roof cleaning might be just what you need to maintain both the look and the health of your home.
A stained roof is generally one that has begun to accumulate algae. Spores get carried by the wind and birds and the issue is generally invisible until there is enough moisture, heat, and humidity for them to grow and spread. Homes that aren’t properly insulated and ventilated are also susceptible to the problem because they hold onto moisture a lot more easily than houses with proper airflow.
If you have staining, the first thing you want to do is find out if your issue is cosmetic or something more serious. Ideally, I recommend that a homeowner gets a roof inspection at least once a year and late spring is one of the best times to do it. During an inspection, a roofing professional will check the entire surface area for shingle deterioration or damage, cracking around the flashing, and will also ensure that water is draining properly through the gutters and downspouts. Something as simple as debris build-up can void the warranty of a roof, so it’s well worth having an expert come and take a look. They will be able to tell you if your stains are something that can be taken care of with simple cleaning or if there is a bigger issue.
If your staining is cosmetic, a roof cleaning takes a few hours depending on the size of the area and one application does the job without the need for pressure washing which can damage the shingles. A roofing expert will use a professional cleaner that adheres to the growth but doesn’t harm the roof or any vegetation below it. Working on a roof is a very dangerous job and I never recommend for a homeowner to do a task like this themselves unless they are very comfortable on a ladder and with heights. No home maintenance task is worth a trip to the emergency room.
If your roof staining is showing up in the attic, your home is one of many in this area that doesn’t have the right airflow and you may want to discuss insulation and ventilation with a qualified roofing professional. Mold and algae in the attic can easily start to affect the air quality in your home, which is especially worrisome for elderly adults, young children, and anyone with respiratory issues. Don’t put this problem on the back burner, talk to an expert right away.
