Why SBS for Calgary Buildings
SBS (styrene-butadiene-styrene) membrane stays flexible in deep cold, so it resists the cracking that destroys lesser flat roofs through Calgary's constant freeze-thaw. The two-ply build gives you redundancy against leaks.
Our Process
We install the base and cap sheets with fully detailed flashing and proper drainage slope, so water moves off the roof instead of ponding and finding a seam.
