How to spot mold or mildew

You can tell if mold or mildew has grown on your roof by looking for telltale streaks of discoloration. The unsightly splotches can range in color from grey to dark-green or black, and mildew can have a slimy appearance and unpleasant smell.

 

How mold and mildew can damage your roof

In addition to being unattractive, mold and mildew feed on and breed dampness that can result in damaged shingles or rot. Left unattended, mold and mildew can spread on the exterior of your roof as well as interior walls and ceilings, compromising your home’s structural integrity and ultimately requiring a very costly repair.

Beyond the damage to your roof, mold and mildew pose a serious health hazard, making it doubly important to be on the lookout for and tend to as soon as its presence is discovered.

 

How to clean mold and mildew from your roof

There are a variety of methods for removing mold and mildew from your roof, including do-it-yourself measures. Most home remedies involve washing the affected shingles with a bleach mixture, making sure to protect any plants or flowers below that may catch the run-off from the cleaning.

If you opt to take care of the cleaning yourself, steer clear of using a power washer to apply the cleanser to your roof or to rinse it off. The force of such a concentrated stream of water can damage shingles, and even reduce their ability to repel water, which will lonely serve to perpetuate the mold and mildew problem.

To be sure that you’re completely removing all traces of damaging and dangerous mold and mildew from your roof without causing any further harm, consult a professional roofer. They’ll use their extensive experience and training to assess your roof, determine the exact nature of the problem, and implement a solution that’s safe and effective.
