Roof Problems & Damages

Everything you need to know about your roof.

Roof cleaning as an industry is very new. Bursting onto the scene in the late 1980’s and early 1990’s there have been as many methods for cleaning roofs as the organisms growing on top of them. Roof cleaning initially was certainly a "garage art" at best.

Pressure Washing Is Dangerous For Your Roof

Pressure Washing is dangerous for cleaning roofs. Though pressures less than 800 psi at the pump head can be acceptable for rinsing away dead algae, using any gas operated pump on a roof is a professionals job. Pressure washing should never be used for direct cleaning of a shingle roof’s surface. In fact, at the nozzle of the spray gun the water pressure should not exceed 150 psi.

Why Shingles Breakdown

Shingles break down from decomposition caused by algae and fungal filament root systems. In the picture to the left, you can see how the shingles have cracks in them, they are curling and swelling. Shingles break down because algae and fungus have a hunger for limestone fillers. Limestone, which contains phosphates, is an excellent source of nutrients for algae and fungus. Shingles break down from the waste created by the algae and fungus metabolizing the limestone fillers. This waste is acidic and damages the shingles. Shingles break down because of excess heat caused from the darkening of the shingles. The darker the shingles get from algae streaking, the more heat they absorb. This excess heat dries the shingles and ages the petroleum in them.

Damages asphalt protected layers

Poured driveways and other flat concrete is tapped to send floating stone aggregate to the bottom of the slab. This way the rocks are not visible at the surface. Then the concrete finisher adds a broom stroke to the concrete for non-skid and decoration.

When these areas are frequently pressure washed the broom stroke erodes away along with layers of the concrete. The stones that were tapped down deeper into the concrete become exposed. Professionals using SoftWash equipment have been trained to use chemicals to make the job easier and reduce high pressure erosion

Roof Maintenance

There are many types of shingle roofs. More than types, there are styles and colors. From the most basic shingle pattern to the highest end products, all are made of similar materials. There are three tab shingles as well as architectural shingles. There are 20, 30 and 50 year ratings. Colors designed to reflect light and heat and colors that blend into the buildings overall color scheme. No matter what type rating and color roof is on a building, roofs are expensive and require maintenance like any other building surface.

Granular Loss

Granular loss can be explained in several different ways. The loss of aggregate from composition shingle roofs is not uncommon. It is actually a part of the life cycle of the shingle itself. To understand granular loss you must understand why the granules are there themselves. The layers of a shingle are simple. Layer one is the fiberglass mat that makes up the body of the shingle. Layer two is petroleum asphalt. Finally, layer three, is the shingle aggregate itself.

Damages asphalt protected layers

Weathering is one of the most common ways aggregate is removed from a shingle roof. Hail storms, hard rain, wind and damaging UV rays from the sun can wear away at a roof little by little. Some of the aggregate on your roof is actually “sacrificial” for that reason. The manufacturer of the roofing materials will add 30 to 40% more aggregate to the roofing surface to account for initial loss in the first three years as well as weathering.
