Tips To Help You Protect Your Shingles From Algae Discoloration

Algae build-up is one of the main causes of shingles discoloration. If you allow algae to build up on your roof, soon your shingles will have numerous brown and black spots that may become nearly impossible to clear, especially if left on the roof for a long time. Below are some effective tips and precautions you can use to control algae build-up on your shingles and prevent roof discoloration.

Use the Right Cleaning Chemical

Cleaning out algae growing on your roof is one effective way you can prevent roof discolouration that results from algae build-up. It's advisable that you consult a roof services specialist who may advise on the best cleaning solvent you should use on your shingles.

Some roof cleaning chemicals can be extremely harsh on the shingles and as a result the chemicals may corrode the surface of the shingles. It's best to keep the frequency of cleaning your shingles roofing at a minimum. For instance, you may want to clean your shingles only when you notice algae growth and not on a routine basis. Otherwise, hire a professional to assess your roof occasionally and let you know when it's necessary to clean out the algae.

Fix a Metal Strip on the Roof

Fixing a metal strip made of zinc or copper below the ridge on your roof helps control growth of algae on your roof. When it rains, the metallic strip produces some compounds that inhibit the growth of algae on your shingles. However, it's not advisable to collect water running off a roof with a zinc strip because the metallic zinc compounds produced can pollute the water, advises The American Institute of Architects.

It's best to hire a professional roofing specialist to fix the metallic strip on the roof. Remember that shingles are delicate and can be damaged or broken if you hire an amateur to fix the metallic strip for you.

Remove Overhanging Trees

Trees too close to your roofing and overhanging branches lying over your roof can promote growth of algae and it's advisable that you cut them back. Trees often cast a shade on your shingles and also drip water on the shingles when it rains. The shade and moist conditions created by the tree are highly conducive for algae growth and may trigger rapid and extensive growth of algae on your shingles.

If you have a big tree near your roof, consider hiring a tree removal service provider to uproot the tree for you. Otherwise, if the problem is the overhanging tree branches, then cut them back. Also, remember to sweep out any leaves, debris and branches on your shingles, because they can cause long-term wear and staining.

Don't let algae build-up discolour your shingles roofing. The tips provided above can help you keep algae growth at bay and aid in maintaining the appeal of your shingles roofing.
