I live in PA. How should I clean my asphalt shingle roof?

There is only one proper way to clean your PA roof without damage and without voiding any warranties. That way is by using non pressure chemical cleaning! The Roof Cleaners have written a lot of information on the proper ways to clean asphalt shingle roofs in Pennsylvania. If you use the proper chemicals, you will not need to use any pressure to remove those algae streaks on your roof. Think about it this way, do mold remediation companies use pressure to kill the mold in your home? NO, they use chemicals to kill the mold. The use of the proper chemicals is the only way to ensure you kill all of the algae and it will give you a longer, better cleaning than pressure washing does.

There are a lot of companies out there claiming to have the only safe roof cleaning chemicals. There are a lot of claims on the internet that are unfounded. Some claims are complete fabrications! The best way to find the truth out about the proper roof cleaning chemicals is to find an association that represents asphalt shingle manufacturers and ask them what the approved cleaning method is. They will not recommend any chemical that will damage or void your shingle warranty! Here is a link to the Asphalt Roofing Manufacturers Association. They are an association of the largest shingle manufacturers in North America! They recommend only one combination of roof cleaning chemcials to remove the algae from your asphalt shingle roof. This chemical combination has a very, very short shelf life. When it is combined, it will last less than two weeks before the cleaning power is rendered ineffective! With this in mind, if you come across a company that is selling roof cleaning chemicals over the internet, steer clear of them! With a shelf life of 2 weeks or less, you would not be able to sell this product. It would be ineffective before you received it from that company. If a company is selling roof cleaning chemicals they have a vested interest in making sure they convince you that they have the only roof cleaning chemical that works. Listen to professional non pressure roof cleaners about the proper cleaning chemicals. They are not trying to sell you chemicals. They are not using pressure to clean your roof. They are following the only shingle manufacturer approved cleaning process!

Some companies claim to use a low pressure rinse to clean your roof. That low pressure rinse is accomplished by using an apparatus up on the roof that is attached to a pressure washer with the pressure cut down to under 1000 psi. That is still way too much pressure! Every day rain storms remove some of the protective granules from your shingles. Look in your gutters some time and you will see shingle granules laying in the bottom of them from the force of the rain. The force of the rain is nowhere near the force being put out by one of these "low pressure" rinsing tools! Remember, if you are using the proper cleaning chemicals, you will not need to use pressure to remove the streaks! The proper chemicals remove the streaks for you!

What Are Those Black Streaks On My Pennsylvania Roof?

Got Roof Stains or Streaks? Does your Pennsylvania, Delaware or Maryland roof need to be cleaned? The Roof Cleaners, based out of Chester County Pennsylvania, are your number one roof cleaning experts in the tri-state area! 610-842-2104 or www.cleanmyshingles.com for a free estimate!

The black streaks on your roof are called Gloeocapsa Magma. It is a form of very hardy algae that grows on the northern exposure of your asphalt shingle roof! It is a living organism and actually feeds off of the crushed limestone that is used in the shingle manufacturing process. If left uncleaned, the algae will continue to grow until your entire roof is covered in thick black streaks!

The only safe way to clean your asphalt shingle roof is with a no pressure chemical application that actually kills the algae and keeps you roof clean for a longer period of time. Some companies use pressure to clean the algae from you shingles. It will look clean after they use this high or low pressure, but it will not stay clean as long. There will also be significant shingle damage after the use of pressure on your roof! Regular rainfall will remove some of the protective granules from your shingles. Imagine what 500 to 1000 psi will do to those same shingle granules!
