Membrane roof cleaning maintenance

White single-ply roofs will get dirty from debris, mold and pollution. To get the most of the sun’s reflective rays, as well as enhance the aesthetics of the roof, it’s wise to have your roof professionally cleaned. At WNC Pressure Washing and Roof Cleaning we are trained in the proper techniques to clean the roof membrane, OSHA safety training and we use environmentally safe solutions.

What type of roof do I have?

 Ethylene propylene diene monomer rubber (EPDM) is a synthetic rubber most commonly used in single-ply roofing because it is readily available and simple to apply. Seaming and detailing has evolved over the years and is fast, simple and reliable with many membranes including factory applied tape, resulting in a faster installation. The addition of these tapes has reduced labour by as much as 75%.

Thermoplastic Polyolefin (TPO) single-ply roofing. This roofing material can be fully adhered, mechanically fastened, or ballasted. TPO seam strengths are reported to be three to four times higher than EPDM roofing systems. This is a popular choice for “Green” building as there are no plasticizers added and TPO does not degrade under UV radiation. It is available in white, grey, and black. Using white roof material helps reduce the “heat island effect” and solar heat gain in the building.

Coal tar is an aromatic hydrocarbon and a by-product from the coking process of the coal industry. It is historically in abundance where coal is used in steel manufacturing. It ages very slowly through volatilization and is an excellent waterproofing and oil resistant product. Roofs are covered by heating the coal tar and applying it between layers of tar paper. It has limitations in regards to its application on dead level or flat roofs with slopes less than 1/4 in 12. 

Polyvinyl Chloride (PVC) membrane roofing is also known as vinyl roofing. Vinyl is derived from two simple ingredients: fossil fuel and salt. Petroleum or natural gas is processed to make ethylene, and salt is subjected to electrolysis to separate out the natural element chlorine. Ethylene and chlorine are combined to produce ethylene dichloride (EDC), which is further processed into a gas called vinyl chloride monomer (VCM). In the next step, known as polymerization, the VCM molecule forms chains, converting the gas into a fine, white powder – vinyl resin – which becomes the basis for the final process, compounding. In compounding, vinyl resin may be blended with additives such as stabilizers for durability, plasticizers for flexibility and pigments for color.

Modified bitumen membranes are hybrid roof systems that combine the high technology formulation and prefabrication benefits of single-ply with the traditional roofing installation techniques used in built-up roofing. The membranes consist of factory-fabricated layers of asphalt, modified using a plastic or rubber ingredient and combined with a reinforcement.

 

 

 

Are you losing money through your roof?

TPO membrane temperature roof test

There are several products on the market advertising that they will help keep your TPO membrane roof spotless. Over time, you figure out nothing quite works like a simple power wash. We recommend you clean your TPO with a pressure washer at least once annually to prevent mold growth and keep your roof free of leaves, tree limbs, dirt and debris. Most if not all manufacturers include anti-fungal or algaecides within the TPO roofing, but they can lose effectiveness over time, and regular cleaning is needed.  When your commercial membrane roof becomes dirty, you lose money when your utility bills raises due to increased heat. Call 828-331-8118 to find out more.
