Single Ply roofing membranes are made out of a variety of different materials. The key is that they are installed as only a single layer which makes them quicker and easier. They are resistant to UV radiation which is an important feature. The finish can be either black or white.
EPDM is the acronym for a long chemical name for a special roof covering that is pretty much made up of rubber. It is a thin sheet that comes in a roll and is laid out on a roof deck and glued at its edge and seams and rolls out to form a sort of “pool liner” on the roof. EPDM is an excellent roof system; lasts a very long time and does not require any UV protection as the rubber has been cured with its own protection. It is often used with “ballast” which would be 1" or 2" stones to weigh it down so as not to be lifted in strong winds.
TPO is another single-ply membrane similar to EPDM and is often made by the same manufacturers as EPDM. It generally comes in two colours, grey and white, and is considered a very "cool" roof.
On a very hot summer day, it is pretty well impossible to stand barefoot on a Torch-on roof. However, the TPO is amazingly cool. This is positive as big cities and metropolitan areas are trying to reduce the heat they give off.
TPO also does not require an open flame, much like EPDM. However, the TPO is welded together at the seams and joints using a hot air welder. This is quite a reliable system and the rolls can come as wide as 10' or more. Thus, it works well in large commercial environments.
Over the last few years TPO roofs have started to become more wide-spread on smaller commercial buildings, and even on residential houses and decks. It can be used in tight spaces and applied quite quickly. It can even be applied over an old tar and gravel roof without having to remove the entire old roof.
Absolute Roof Solutions is very excited to be authorized dealers of Duro-Last which we consider to be the world’s best...
Duro-Last Roofing Inc. began producing its PVC roofing systems in the mid-1970s. Over two billion square feet of the Duro-Last PVC roofing system membrane have been installed on all types of commercial, industrial, and institutional buildings throughout North America.
The Duro-Last roofing system, made from a PVC membrane, is highly durable and resistant to fire, chemicals, grease, high winds, and punctures, and easily accommodates wide temperature extremes.
Every Duro-Last single-ply roof is measured and manufactured to the exact size, accommodating every rooftop penetration. Prefabricating the vinyl roof membrane in a controlled factory environment eliminates up to 85% of seaming that is done on-site during rooftop installation, and improves the long-term performance of the roofing system as well reduces the material waste associated with the installation of most rolled systems. This precise attention to detail ensures an excellent fit and delivers worry-free, leak-proof protection.
Installed With No Disruptions
Building occupants will hardly know a new roof is being applied because installation is quiet and safe. Duro-Last’s PVC roof membrane is mechanically-attached to the deck; edges and vinyl roof components are heat-welded together to complete the watertight, monolithic roofing system installation. There are no loud machines, no hazardous materials, no noxious fumes, no hot tar, and no mess. Because it's made from lightweight vinyl, a new Duro-Last roofing system can often be installed over an existing roof without an expensive tear-off, virtually eliminating dust or falling debris that could interfere with building activities or damage sensitive equipment.
PVC roofing systems make an important contribution to sustainable buildings, and Duro-Last is proud to be a charter partner in the EPA's ENERGY STAR® Roof Products Program. Duro-Last is a leader in cool roofing solutions, and the Duro-Last Cool Zone® brand addresses the growing nationwide interest in sustainable roofing systems.
Of the white, single-ply products rated by the ENERGY STAR program, only the Duro-Last Cool Zone roofing system has retained reflectivity of greater than 85% after three years of weathering (based on ENERGY STAR roof products testing criteria). The high sustained reflectivity delivered by our white PVC roofing membrane is a leading sustainable building product, saving significant energy and money for building owners.
