What is a roof mold?
Are you concerned about the black streaks on your roof, its siding, deck, and patio, but you’re not sure what they are? Most people confuse algae with roof mold so below is a table to properly identify which is which.
Based on the table above, unlike the algae, mold can cause health problems in the home like asthma, irritated eyes and throat, rashes, fatigue, headaches, and lung issues. That’s why it’s important to identify algae from a mold and determine what exactly the streaks on your roof are.
If the interior of your house is intact or unmarked, you’re more likely just dealing with algae.
Algae don’t harm your roof or your loved ones. They just look bad.
It is best to inspect your crawl spaces, which are the attics and basements a few times every year to be sure mold isn’t silently forming under your nose.
Aside from the signs above, you can spot a mold by looking out for the following:
- gray or brown ceiling discoloration
- obvious mold growth (brown, dark green, or black)
- musty odor near the area of a leak or stain
How to remove them
Prevention is always better than cure
You read it right. The best way to deal with mold is to prevent the growth. You must conduct regular house and roof washes to make sure every part is sparkling and safe.
If ever a mold growth happens in your house or on your roof, it is easier to leave it to the professionals.
However, if you still prefer to ‘do-it-yourself’, you can use pressure washers and soft brushes to get rid of the mold.
Before starting, keep in mind that the most common mistake in using pressure washers in DIY cleaning is applying too much pressure. Aside from damaging your home, you can also hurt yourself when you use too much pressure. Yet, using too little pressure won’t remove the stains.
Then, follow the steps below to remove the mold.
- Assess the extent of the damage. Don’t just deal with the visible mold growth. What you see might not be the extent of the growth. Mold grows anywhere with water such as your attic, basement, roof, siding, deck. You should also look out for mold near leaking areas like the ceilings, floorboards, drywall, and insulation.
- Remove the mold growth. This only applies to mold growth in a small area. If the growth is too big to manage, call a professional immediately. The first step is to clean the affected area of the roof with a soft-bristled brush. You can also use pressure washers if your roof is not made of asphalt shingles. However, you can use bleach or sodium hypochlorite as a disinfectant on this type of roof.
If the damage is too big, you will need a new roof.
Mold growth is a serious problem and should be dealt with a professional. Moreover, if you do-it-yourself, you might miss spots and just focus on major parts of the roof. Some damage can be intensive and invisible to the untrained eye.
Professionals will not only remove the mold growth but also make sure they don’t come back.
