How to Safely Remove Mold From Your Roof

How to Safely Remove Mold From Your Roof

Locating mold on your roof can be extremely frightening. If neglected, mold growth can spread to such a degree that not even a pressure washer can help. In these instances, you’ll need a full roof replacement. To avoid the cost of a roof installation, you’ll need to know how to safely remove mold from your roof.

Step 1: Is it Mold?

Before you go about removing the mold, are you absolutely sure that it is mold or mildew? Mold grows from an excess amount of water and moisture in the air. Darker stains and streaks along your roof may look like mold, but more often than not it’s blue-green algae. 

Usually, blue-green algae is the culprit in situations like this. In less common cases, moss and algae can spread on your roof from wind, birds, squirrels, etc. If you can have a roofing contractor rule out both blue-green algae and moss growth, then you’re looking at mold. 

Step 2: How to Clean Mold

Ignoring mold can lead to both costly roof repairs and health problems for you and your family. Now that you know you’re dealing with mold, how do you go about cleaning it? To make the process simple, we’ve broken it down into 5 steps:

  1. Clean your roof on a calm cloudy day. If done on a sunny day, the bleach mixture could evaporate too quickly, lessening its effects. 
  2. Do not use a pressure washer to clean your property. It could loosen your shingles and gutters, and leak to a hefty roof leak repair charge. 
  3. Determine if your roof is safe enough to walk on; slip-resistant shoes are recommended by professionals when walking on a roof. However, do not spend too much time up there. Frequently climbing on top could damage your roof and loosen the shingles.
  4. Use a sprayer attached to any typical outdoor garden hose. Prepare a mix filled with equal parts chlorine bleach and water. This works especially well on asphalt shingles. After spraying the mixture across the whole top, and let it sit for 15-20 minutes before rinsing it with water. 
  5. Do not overdo it with the mixture. In this case, less is more.

Step 3: How to Prevent Outdoor and Indoor Mold

To prevent the growth and spread of mildew in the future, routine maintenance is necessary. Moss, blue-green algae, and mold love cool, damp environments, so it’s highly recommended to trim any overhanging branches above your home to reduce the spread of these.

The presence of standing water can also lead to the growth of mold. Whether it’s in your gutters or on your roof, standing water can bring about leaks and water damage. From there, it then leads to the development of mold. Roof leak repair in Englewood, Ohio is no joke, so be very wary and cautious when it comes to standing water.
