How to Eliminate Roof Mold


Mold can grow anywhere as long as moisture is present, and the roof is no exception. Your roof can fall victim to an infestation of moss and lichen; two types of mold that can cause wood and shingles to rot. If your roof is covered in mold, eliminate the issue as soon as possible.

Make sure that you’re fully prepared with the proper safety gear before heading up to the roof. Use a ladder that is sturdy, a harness that is secure, and protective gear for your body. If you can’t find yourself a hazmat suit then you can opt for long sleeves, boots, gloves, goggles, and a face mask.

Elbow Grease
The first step in the removal process is to scrub the moss, algae, or lichen away with water and a scrub brush. Put some elbow into your scrubbing, but not too much because you don’t want to damage your shingles. Try to eliminate all of the moss and lichen because any that is left on the roof will continue to damage it in the future.

Once all of the moss and lichen has been removed, rinse off the entire roof with water. A garden hose is preferred because a pressure washer will damage the shingles. Afterward, spray down your roof with a mold killing roof wash, followed by another quick rinse. It’s important to remember the plant life that surrounds your home during the mold removal process. Wash them off with the hose after so they are not covered in moss, lichen, or the mold killing cleaner.

Eliminating roof mold before it gets too bad will help increase the longevity of your roof and value of your home. Cleaning up mold on a roof and repairing any broken shingles can be a dangerous job so you may want to leave it to the professionals at Preferred Exterior.
