Mold on your roofing can cause unsightly dark stains and patches. This problem is especially prevalent in warm, humid climates, and Hawaii is no exception. Not only does mold diminish the appearance of your home or business, but it can also be a dangerous health problem if it permeates inside the structure. Treating the problem quickly and effectively is essential, which is why the roofing professionals at Tory’s Roofing & Waterproofing, Inc. in Pearl City, HI, offer a few ways you can treat this problem.

How to Remove Mold From Your Roofing

Clean With a Bleach Solution

The easiest and least expensive treatment is to mix a solution of 50% water and 50% bleach, and spray it directly onto the problem area. To protect plants on the ground that might come into contact with the solution, spray them with water first. Leave the solution on the shingles for about 15 minutes, and then rinse thoroughly with clean water. This treatment is not a long-term solution, however. The mold may return over time, so you’ll need to spray again later on or find a more permanent fix.

Increase Exposure to Ultraviolet Light

If large trees and branches are providing shade to your roof all day, trim them back. An increase in ultraviolet rays from the sun will kill off mold spores. This will also help lessen the amount of moisture that remains on your roof from rain, further diminishing the conditions mold needs to grow.

Repair Leaks & Replace Damaged Shingles

Repair roof leaks and damaged gutters right away to prevent moisture from accumulating. Broken shingles and excessive shingle overhangs should be replaced as well. If moisture has damaged your building’s paint, re-cover it with a mold-resistant option to prevent recurrence and protect your home.
