K Single Corp Roofing & General Contractor specializes in the installation of thermoplastic membranes (PVC, TPO).
The most common thermoplastic roof membranes are PVC and TPO. The following provides general descriptions of these two systems, low slope (flat) roofing includes water impermeable, or weatherproof, types of roof membranes installed on slopes less than or equal to 3:12 (14 degrees).
There is no one roof system that is best for all applications. Keep in mind that even if you are using the best materials, your roof system still can be installed improperly and you could end up with a leaky roof.
Good workmanship and proper attention to detail (flashing and drainage issues) are just as important as material selection. Also, maintenance plays an important role in roof system integrity and service life.
TPO roof systems have been installed in the US for the last 30 years. TPO membranes are made with a co-polymerized rubber that allows them greater flexibility in cold climates.
This membrane is best recognized for having the benefits of EPDM and PVC systems, at a more economical cost. TPO membranes are white and highly reflective, making them an excellent choice if you're looking to reduce energy costs.
In addition to being ENERGY STAR rated, TPO’s recyclability makes it an excellent choice if you're environmentally conscious.
The PVC roofing membrane has an extensive installation history in the roofing industry. First installed in the early 1960’s PVC was the industry’s answer to the oil crisis, as it was the first membrane to contain half of the fossil fuels normally used in system manufacturing.
Engineers discovered that adding additional solid plasticizers to the PVC membrane allowed for additional weatherability and flexibility, where the membrane alone would be more susceptible to seasonal climate changes. PVC membranes are incredibly versatile and chemical resistant.
They are available in a variety of colors, thicknesses, widths, and reinforcements, making them an excellent option for almost any roofing project. PVC roofing is highly recommended for roof-over projects.
Along with the environmental benefit of using (fewer) fossil fuels in the manufacturing process, PVC is highly reflective/UV resistant, making the membrane an energy-efficient option for warmer climates.
Better known by their street name of tar & gravel roofs, BUR is just that. Built up roofing can include up to four plies or more consisting of alternating layers of bitumen (asphalt, coal tar, or other adhesive) with a topping aggregate layer of gravel or other materials.
Built-up roofs have been in use for over 100 years with their biggest advantage being the ability to withstand heavy foot traffic. Membrane roofs are durable… in a sense, but a gravel coating can withstand heavy collisions. For more information about our flat roofs, contact us today.
