One of the easiest ways to save money on roofing is to move to a roofing maintenance program. Many of our major corporate and institutional clients have added up to 50% more service life to their roofs and realized significant savings on costly repairs and premature replacement.

This liquefied material is used in inverted roofs where insulation and ballast rest on top of the “pour-and-cooled” two ply membrane. It bonds to the substrate forming a monolithic skin over the roof, creating a vapor and air barrier. Its elastomeric base gives the Hot Rubberized Asphalt roofing system a “self-healing” property.
Cold Applied Systems Multiple plies of organic or inorganic felts can be laid in the roofing system using cold adhesives. This can be advantageous when the use of hot materials is not practical.
¡ PVC is the only single ply membrane that is recyclable and most commonly found in white but is also available in custom colours with roll widths available in 5’, 10’ and up to 100’ long. PVC Membrane seams are hot air welded together.
EPDM is a single ply rubber sheet. Most common in black but is available in white with a standard thicknesses are 45, 60 and 90 mil and come in almost any width up to 50’ wide. The joining of EPDM sheets are bonded together using seam tape.

Waterproofing is seldom visible yet vital to the
performance of a building. It takes considerable knowledge and
experience to implement the correct waterproofing system based on your

non-existent flashing on roof penetrations and junctions can lead to
leaks and cause your roof to deteriorate faster than it should.
