Algae and moss growth could mean serious trouble for your roofing. Oftentimes, this becomes a recurring problem, and it can cause unsightly stains on your roof surface. Fortunately, there are ways to prevent the growth and spread of algae and moss.

How Moss and Algae Affect Your Roofing

In order to protect your roof from algae and moss stains, you need the right information regarding these elements.

Moss requires a moist environment in order to thrive, so you have to be particularly wary of moisture buildup in your roofing system. Make sure that your roof is able to shed water or melted ice effectively. Your gutters should also be in good condition so that water won’t back up onto your roof. Take note of any tree branches that are hanging over your roof as well. They typically provide shade and drop debris on your roof, which can further attract moisture and serve as a food source for moss.

Moss tends to be more detrimental to asphalt shingles than algae. For instance, it can cause the edges of the shingles to lift or curl, increasing the likelihood of a shingle blow-off during severe wind events. Furthermore, moss buildup can also cause lateral water movement, which can lead to roof leaks or moisture damage to the roof deck.

Tips on Preventing Moss and Algae Growth

Below are some measures that you can take to discourage the growth of mold and algae:

• Clean your roof on a regular basis so that debris won’t accumulate. You can use a leaf blower or a similar, non-abrasive method of clearing debris from your roof.
• Trim tree branches to help minimize debris and other droppings on your roof. This will also allow more sunlight to reach your roof.
• Make sure your gutters are free of dirt and debris buildup so that they can continue draining water effectively. Check the placement of your downspouts as well. Gutters from an upper roof should not drain directly on a lower roof.
• You can add zinc or copper strips on a new roof to prevent algae and moss. Alternatively, you can opt for asphalt shingles with algae-resistant copper granules when it’s time to replace your roof.
