Roof Cleaning – The Right Way

Chemical roof cleaning is a superior alternative to roof power washing, which you may already be aware of. These days, there are many roof cleaning products and solutions on the market, all claiming to be superior, and all claiming to be the safest and most reliable, but it is important to bear in mind that these are businesses who are just trying to make a buck and are going to say just about anything to sell their product.

There is only one way to clean a roof the right way, in my vast experience, and that’s with a solution based on sodium hypochlorite. Sodium hypochlorite is the active ingredient in bleach and chlorine, and is very literally the easiest, most effective way to disinfect a roof when added to a roof at the correct ratios. It is the preferred method by ARMA (the Asphalt Roofing Manufacturers Association) and GAF (the largest shingle manufacturer in North America) for cleaning roofs. Do you want to learn more?

ARMA suggests a combination of bleach, water and TSP (which can be found in paint shops), but be careful to remove gloss at high dosages with the TSP on painted surfaces. I found that, since the bleach is the primary cleaning agent, the TSP is helpful but not necessary. Furthermore, every roof cleaning professional using this method has its own “secret” additives that they add to this mix to give it just the right cleaning power for their environment, but a final liquid solution that is around 3-4 percent sodium hypochlorite is the common denominator. So you will need to have equal parts of bleach and water to get you down to 3 percent if your typical household bleach is around 6 percent.

This is by far the easiest and most effective way to clean a roof, but the catch is that anywhere from 30 to 60 gallons of total mix would be needed for an average one-story ranch house. That means you’d need a standard 6 percent household bleach of around 15-30 gallons. Usually, in a large poly tank on their truck or trailer, the pros will have the whole mix and will use a battery-powered pump to deliver the solution to the roof surface through a long polybraided hose. Typically, at the end of the hose, they would have a bleach resistant tip that disperses a gentle spray uniformly across the surface of the roof. Before rinsing the surface with water from the garden hose, they’ll leave the solution on the surface and let it do its thing for several minutes. So there should be no need for power washers or scrubbing (the only exception could be for thick moss accumulations). If you do this yourself, during the application, you may also want to keep the entire perimeter of the home rinsed down very well (preferably by a second person) because if not properly diluted, sodium hypochlorite may have a detrimental impact on landscaping. Be particularly conscious of areas in which downspouts empty into grass or other greenery.

Features And Advantages of Solar Roof Tiles

Many home owners today tend to add solar roof tiles along with the current roofs. The typical roof-mounted solar unit types are voluminous and inconvenient. As it has different beneficial features, it is considered to be one of the best alternatives. In various shapes and sizes, photovoltaic tiles are available to fit different home requirements. The current roofs of homes can easily be interlocked seamlessly. 

Ultra thin layers of photovoltaic materials that are neatly built directly into the tiles comprise these solar shingles. It helps to turn sunlight into renewable energy when installed, which can be used to heat households and generate electricity. For future use, the surplus energy that the shingles generate is retained in the grids.

While initially the solar shingles are very costly, it is known to be cost-effective as it lasts for a long period of time and helps to decrease overall energy consumption. In addition, relative to other fuel types, it is also eco-friendly.

Advantages of Solar Roof Tiles:

Initial cost: While it can be very costly to install these shingles directly onto the existing roofs, it provides successful results in the long term. As it needs prior experience, it is important to seek the support of professionals to install these tiles.

Aesthetics: It is aesthetically pleasing, one of the key advantages of using solar shingles. Without distracting the roof lines, it compliments the style and existing architecture of homes. These tiles are formed and made to match all kinds of roofs. It can also be very easily integrated into conventional kinds of roofs. These tiles, however, rarely give absolute invisibility. It is available in a variety of colors that are subdued, such as yellow, dark blue, etc.

Efficiency: These tiles are made from thin solar cell films. It is, however, considered to be less effective than solar panels that require huge modules based on silicon. But these tiles can be used in areas where installation of solar panels is difficult. It can be used for the heating of an entire home. The efficiency of these tiles depends on the shading, orientation of the roof and solar energy exposure. Therefore, prior to installing shingles on the roofs, it is very important to consider these details.

Durability: There is an improved life span of 30 years for solar roof tiles. Most of these tiles are built in such a way that they can be replaced as needed. To produce electricity in an acceptable manner, it also protects the roofing materials and insulation. There are several businesses providing warranties and assistance with installation.
