Roof Cleaning - Low Pressure Cleaning

What are those

black streaks on your roof?

Black streaking is the first sign that your roof shingles are the source of life for a type of bacteria called Gloeocapsa Magma. This bacteria feeds on the limestone in the granules of the shingles and starts to hold moisture. With moisture being held longer than it should this can cause pre-mature deterioration of the roofing shingles. Where there is moisture, algae and moss may start to grow if left untreated. The algae and moss once present will start to spread under shingles causing them to lift and another entry point for water intrusion to happen. So how do you prevent this and protect your investment?

Protect your Investment

While cleaning your roof may cost a couple hundred dollars to remedy, taking action now will save a fraction of what it would cost if left untreated and needs to be completely replaced. Insurance companies are requiring that roofs be in good condition and signs of aging can cause a home insurance provider to drop coverage due to an unkempt roof. Your roof is the first line of defense against the elements and if let go can cause structural damage before being spotted by a leak in the ceiling with rotting wood taking place behind the walls.

Maintain the Warranty of your Roof

We follow a strict process when cleaning a clients roof. ARMA (Asphalt Roofing Manufacture Association) recommends a low pressure, chemical cleaning that is within the manufactures warranty cleaning process. Not only are you prolonging the life of your roof but you are also staying within the warranty to guarantee more life from your roof.

Extend the life of your Roof

Early detection and cleaning will help extend the life of your shingles. By killing the bacteria at the source you are preventing any future growth and ensure that your roof is well maintained and free of any potential harm.

Save Money on Cooling Costs

Shingles are designed to reflect the sun to keep the attic space cool. When algae starts to grow and causes discoloration, this allows your roof to hold on and absorb heat. This in turn heats up your attic space which causes your AC to run more throughout the warmer months. By cleaning the roof and keeping your shingles in their peak performance state helps save on cooling costs by not overheating your home and running the AC more.

Professional Paver Cleaning, Sanding and Sealing Service

Blue Water Power Washing is trained and a Certified Applicator from Deco Product s to clean, sand and seal. We follow their recommended process when cleaning to prepare for sanding and sealing. The process takes multiple steps to achieve a professional result. -First we start by applying an algaecide to kill all organic growth to make cleaning the pavers with higher pressure easier. -Next step is to use a high pressure turbo nozzle tip from a safe distance to blow out all the old sand in between the pavers to get rid of any unwanted moss and weeds but without damage to the stones. -We then follow up with a professional grade surface cleaner to ensure a uniform clean on all the paver stones. -Next is to apply a neutralizer to rebalance the pH of the stones, followed by more heavy rinsing -Our preferred method is dry sanding, so after 24-72hrs of cleaning the stones we will return to complete the sanding and sealing -We use ASTM-C144 joint sand. We broom in the sand (color of customer choice) and follow up with a leaf blower to get an excess sand out and make sure there is about 1/8' below the chamfer of the stone. -After all sand has been replaced and leveled, we use a joint stabilizing sealer to protect the pavers from moisture getting in and stabilizing the joints by creating a rock hard seal that won't allow the pavers to move due to natural erosion. This process should be completed every year or two to maintain the integrity of an outdoor paver area. However yearly clean and seals are much less expensive then having to relevel a whole paver area after years of erosion have washed away sand creating a ungulated area
