In Minnesota, flat and low-slope roofs are used on a few homes in the area, and on many outbuildings and small to medium-sized commercial buildings. Our winter snows are the reason most homes have pitched roofs designed to shed snow, so residential roofs in the Minneapolis/St. Paul metro area generally have roof pitches steeper than in some other parts of the country. For those buildings with flat roofs or roofs with pitches less than 2” per foot, Minnesota’s roofing requirements dictate that only high quality roofing practices are adequate. At Coty Construction, we’re often called on to install roofs for these buildings because our quality-oriented roofing produces superior results, handling snow and melt water efficiently and thoroughly. The reason is our attention to detail and uncompromising insistence on top-quality roofing materials and installation.
Flat and low-slope roofs present unique issues. The roofing materials must be completely impervious to water penetration and applied to provide a seamless, sealed, continuous cover for the roof. In Minnesota, the large amount of snow presents additional considerations, since accumulated snow remains on the roof, slowly melting. That melt water must be able to drain from the roof, and the roofing material must keep it from penetrating into the building’s interior. Our Minneapolis/St. Paul metro area roofing company has long experience in installing and maintaining these low-slope and flat roof systems. We used extensively these types of roofing systems, manufactured by CertainTeed, Mule-Hide and other top-quality suppliers, to handle the special requirements posed by these roofs.
Made of synthetic rubber with special formulations to handle the extremes of temperature, sunlight, and accumulating snow that roofs must accommodate for in Minnesota, EPDM membrane roofs are a natural choice for low-slope roofs. Available in a range of thicknesses and installation methods, EPDM membrane roofs are a common solution. This roofing material, installed to create a continuous, waterproof barrier against water penetration, produces ideal results for many building types and designs. Careful installation and attention to detail is required for a quality EPDM roof. Which will result in a sound, leak-free roof that will last. At our Minnesota roofing company, we have the training, equipment, and experience needed to handle installation of your EPDM roof with the same meticulous care and focus on quality and cost-effectiveness we bring to every roofing job.
As another type of membrane roof, these roofs are made up of a mat of synthetic fibrous materials, saturated with a modified bitumen material, and topped with a layer of ceramic-coated granules. Applied over a carefully prepared deck, the roof is a multi-layer assembly, using a base sheet, followed by the granule-coated top layer. Different roof environments use different installation processes. The material comes in rolls, which are placed with overlapping seams. Those seams can be sealed using cold-sealing adhesives or heat welding, depending on conditions and the selected materials. The result is a continuous membrane that blocks all penetration of water. As with all low-slope and flat roof installations, installation must be done with great care and with attention to every detail, including flashings and roof penetrations. The skilled, experienced roofers Coty Construction will install your roof with special attention paid to achieving a long lasting, trouble free roof.
