Is mold on roof dangerous?
It can degrade the integrity of a roof and the value of a house
What are we talking about when we talk about roof mold? If a contractor or inspector says your roof has mold it could mean a lot of things. It could mean actual mold, mildew, black or green bacteria, or even algae. Regardless, those black stains can look bad and damage your roof. Mold will start to grow in the cracks and crevices of your roof where foliage has accumulated or in the shaded parts.
As the mold grows it will slowly deteriorate the roofing material. The blue-green or black algae that grows is most likely stachybotrys chartarum. It will continue to grow and spread unless you do something about it. As long as your roofing material deteriorates, the age and effectiveness of your asphalt shingles will decline faster than what they were industrially built to withstand.
Like moths eating the cloths in your closet, the mold will prematurely age your roof making you more likely to need to replace it sooner than you think. Who wants to buy a house with a bad roof? Maybe if they can get it at a lower price.
Get rid of it with a soft washing professional
Your roof needs proper care and maintenance yearly to clean the growth and freshen the roofing shingles. However, power or pressure washing is too much. The high-pressured water, up to or even over 4,000 psi, can not only destroy the asphalt shingles but also rip them clean off your roof.
Soft washing doesn’t rely on high-pressure to clean. Soft washing professionals use a soapy detergent like your laundry machine to lift the stains and mold. The mold, mildew, dirt, and grime are then rinsed off with a low-pressure, significantly below 4,000 psi, hose system. So, if you need to re-invigorate your roof, get a qualified expert in soft washing to rinse and repeat.
