What causes mold on your roof, and how do you get rid of it? This is a question that many residential roofing contractors in Overland Park frequently hear. No one wants mold, moss, or algae on their roof. It can cause permanent staining, and in some severe cases, cause potential leaking that spreads into your attic or insulation. Taking the time to remove algae & moss from your roof is an essential piece of proper roof maintenance.
Remove Algae & Moss From Your Roof
If you have black mold-like streaks and stains on your roof which appear to be lighter colored, this is considered to be blue-green algae. This type of algae is most commonly found in climates with warm weather and a humid summer. Blue-green algae does not damage your roof, but it does cause ugly stains and streaks.
There are several steps a homeowner can take to resolve this issue. Consult with quality residential or commercial roofing contractors in Overland Park at Rhino Roofing before attempting any form of roof repair on your own.
Replace the Shingles
Replacing all of your old shingles with newer darker shingles will better disguise the staining and streaking. However, this does not resolve the issue, only disguises it. Shingles laced with copper granules act as an opponent to algae. The copper granules in these shingles are lethal to most forms of algae. Although this is one solution, the best roofer in Overland Park won’t encourage this method unless your roof is older, and shingles need to be replaced anyway.
Clean Your Roof
The less expensive method to fighting mold and algae is to spray and wash your roof with a 50% mix of water and bleach. This method is less costly but can be damaging to your roof if you use too much bleach. Make sure to consult with an Overland Park roofing company before attempting any maintenance on your own. To wash your roof correctly, wet your foundation plantings, and then rinse everything in clean water when you’re done. You don’t want to let the bleach rest on your roof any longer than it needs to. Wetting the plants around your roof before washing it with bleach will make it easier for your plants to defend against it. Plain water helps to protect your plants from this damaging procedure.
Every owner of a new roof in Overland Park wants to know how to ensure algae does not come back. Washing your roof can be tedious and not a chore a homeowner wants to do time and time again. Consult with trusted Overland Park roofing companies and insert 6-inch wide strips of zinc or copper under the row of shingles closest to the roof peak. Make sure to leave one to two inches exposed to the weather. Whenever it rains, the water will wash some of the metal molecules down your roof, killing any algae along the way.
