How To Remove Moss From Asphalt Shingles?
Moss growth on asphalt shingles is a common problem, especially in areas with high humidity and moisture. Moss can cause damage to the shingles, as well as create a less-than-appealing appearance on your roof. In this article, we’ll discuss removing moss from asphalt shingles and preventing it from returning.
Why Moss Grows on Asphalt Shingles
Moss growth on asphalt shingles is typically caused by moisture accumulation and lack of sunlight. The shady, moist environment created by overhanging trees, nearby buildings, or a north-facing slope is ideal for moss growth. Once moss takes hold, it can quickly spread and damage your shingles.
Tools and Materials Needed
To remove moss from your asphalt shingles, you’ll need a few tools and materials, including:
- Safety goggles
- Rubber gloves
- Stiff bristle brush
- Garden hose with spray nozzle
- Moss killer solution
- Plastic sheeting
- Ladder
Step-by-Step Guide to Remove Moss from Asphalt Shingles
Follow these steps to remove moss from your asphalt shingles:
Wear Protective Gear
Before you begin, wear protective gear such as safety goggles and rubber gloves to protect yourself from the moss-killer solution and any debris falling from the roof.
Prepare the Area
Cover any plants or bushes near the roof with plastic sheeting to protect them from the moss-killer solution.
Apply the Moss Killer Solution
Spray the moss-killer solution directly onto the moss-covered areas of the roof. Be sure to follow the manufacturer’s instructions for mixing and application. Avoid using a pressure washer, as this can damage the shingles.
Wait for the Solution to Work
Allow the moss-killer solution to sit on the roof for the recommended time, typically 15-30 minutes. This will give the solution time to penetrate and kill the moss at the roots.
Scrub the Shingles
Using a stiff bristle brush, scrub the moss-covered areas of the roof, applying gentle pressure to avoid damaging the shingles. Start at the top of the roof and work your way down, rinsing the brush frequently with water.
Rinse the Roof
Rinse the roof thoroughly to remove any remaining moss and debris using a garden hose with a spray nozzle. Rinse the roof from top to bottom to avoid pushing water under the shingles.
Inspect the Roof
After rinsing the roof, inspect it for any remaining moss or damage to the shingles. If there are still areas of moss, repeat the process until it is completely removed.
Prevent Moss Growth from Returning
To prevent moss from growing back on your asphalt shingles, there are a few things you can do:
- Trim back overhanging tree branches to increase sunlight exposure on the roof.
- Keep the roof clean by removing debris, such as leaves and twigs that can trap moisture.
- Install zinc or copper strips near the peak of the roof, which can help prevent moss growth over time.
- Have your roof professionally cleaned regularly to remove any buildup of moss or debris.
