How to Care for Your Asphalt Shingles

Asphalt shingles may be durable, but they aren’t maintenance free. There are a few things you need to do in order to keep them functional and looking great. Here are a few things to keep in mind when it comes to maintaining your shingles.

Keep Them Clean

Depending on the area of the country you live in, you may need to clean your shingles every few years. Some areas, especially the Southern States, are more prone to having mold and other fungi build up on the shingles.

Pressure Washing

If you choose to pressure wash, make sure you choose a low-pressure wash to avoid any permanent damage to the shingles.


If you are already experiencing problems with mold or fungus, you can remedy this by using a bleach mixture on the asphalt shingles. You can purchase special shingle bleaches at any hardware store. With this, you will use a pump to spray the mixture on the shingles. Let it set, then rinse off according to the manufacturer's directions. These mixtures can damage plants, so be aware of this if you have plants around the perimeter of the house. You may want to take precautions to protect these before you spray.

Zinc Strips

If you live in an area that is prone to moisture and fungus, you may want to invest in zinc strips. These are placed at the peak of the roof across the top. When it rains, a small amount of zinc is then carried down the roof. This will place a light coating over the roof and prevent any kind of fungus from forming. This is a great investment and can save you lots of money later in replacing shingles that have been damaged by fungus.

Replace Damaged Shingles

Having just one shingle that is damaged from storms or fungus can create a much bigger problem later on. It’s best that you inspect your roof at least once a year and replace any shingles that have been damaged or are popping up. If you find shingles that are popping, you can get away with just gluing these back down. If they are damaged in any other way, it’s best to go ahead and replace them.

Keep Extra Materials

When a new roof is installed, it is a good idea to have some extra shingles around after it is complete. It can be difficult to match the color later down the road.
