Our primary supplier for roofing materials is Elevate Building Products Company, LLC. It is the leading manufacturer of superior roofing products, and has “steadily diversified from a single product to a full line manufacturer of EPDM, thermoplastic(TPO), asphalt and metal roofing systems, polyiso insulation and accessories…Elevate unveiled the industry’s first 30-year TPO warranty with the introduction of the UltraPly TPO Platinum Roofing System in 2006.” We obtain the highest quality asphalt and Fibreglass shingles from Building Products of Canada Corporation (BP), Malarkey Roofing Products,CertainTeed Corporation, IKO Industries Ltd., and Soprema.
For commercial and industrial low-slope (flat) roofs requiring a single ply membrane, EPDM roofing systems have proven themselves over the last 30 years. “Durability, design versatility and installation ease are among the many reasons ethylene propylene diene monomer (EPDM) is the most popular material for both new and reroof low-slope roofing applications. Elevate EPDM Roofing Systems are based on a high-performance synthetic rubber compound that provides outstanding weathering characteristics in climates worldwide. From office buildings and distribution warehouses to hospitals and schools, Elevate has an EPDM roofing solution that’s right for you.” (Elevate Building Products)
The roof deck surface is carefully cleaned and prepared according to stringent specifications in order to receive the vapour (or air) barrier. Then (if required) an insulation base sheet is applied, after which R20 Polyiso insulation is installed and fastened, either mechanically or with an adhesive. The EPDM membrane is then carefully attached either mechanically or with a bonding adhesive. If necessary a ballasted system (stone, gravel, or pavers over membrane) can also be installed under the manufacturer’s specifications. Membrane roof systems have exceptional resistance to wind uplift, and have warranties of up to 25 years. There are seven kinds of EPDM roofing systems supplied by Elevate, which provide the widest possible range of solutions for all your roofing needs.

Thermoplastic polyolefin (TPO) roofing membranes are very energy efficient, with superior seam strength, exceptional puncture resistance(including hail), great dimensional stability, and very economical and environmentally friendly. They are among the fastest growing roofing products, with exceptional resistance to ultraviolet, ozone, and chemical exposure with superior reflectivity. The installation procedure is similar to that for EPDM membranes, and Elevate has an exceptional 30 year warranty for Ultraply TPO Platinum when installed under their supervision.There are seven kinds of TPO roofing systems supplied by Elevate, which again provide the widest possible range of solutions for all your roofing needs.

Fibreglass laminate shingles (also called “architectural” shingles) are made of inorganic Fibreglass mat, coated on both sides with high quality asphalt, and covered with protective (sunlight, ultraviolet light, weather resistant) mineral roofing granules.They are installed over an underlayment fastened to the roof deck. Fibreglass shingles are much lighter than asphalt shingles, have the highest fire resistance rating, and also resist heat and humidity. Because they are two to three times more durable than asphalt shingles, they have longer warranties. They are also very esthetically pleasing and come in a variety of colours.Overall they are superior to asphalt shingles. However, incorrect shingle installation can seriously affect their performance.
Asphalt shingles (presently called “organic”) are generally made of organic (wood/rag/paper) fiber felt impregnated with asphalt and coated with ceramic granules. They are installed over an underlayment fastened to the roof deck. They are relatively inexpensive, easy to install and maintain, easy to repair, and come in a variety of colours. However they have very poor fire and wind resistance, and are not as durable as other roofing materials. They are also very heat absorbent and are damaged by high temperatures. If attics are poorly ventilated, they will bake from underneath. They are also subject to mold (mildew) and algae growth. Again, incorrect shingle installation can seriously affect their performance.
