Longest lasting commercial roof materials
The roof of your commercial building is a critical investment. So of course you want it to last as long as possible. Longevity starts with tried-and-true, quality components. To that end, here are the top picks from Vancouver’s commercial roofers for the longest lasting commercial roof materials.
Longest lasting commercial roof materials
Green: green roof materials differ from more traditional forms. A waterproof barrier sits on the bottom, followed by a root barrier, a drainage system, a filter membrane, and finally, plants. The benefit of this layout is the waterproofing layer is protected by all the ones above. The average lifespan is 30-50 years.
Inverted: Similarly to a green roof (itself a type of inverted roof) the waterproofing layer sits below the insulating layer. A ballast layer composed of gravel, stones, tiles or pavers protects it all. This type of layout boasts exceptional durability and imperviousness to freeze/thaw cycles. It can also be installed quickly. Average lifespan is 25-40 years.
Torch-on: torch-on is a lighter, improved version of BUR roofs (tar & gravel with a lifespan of only 10-15 years). It is installed using bitumen base sheets covered by 1 or 2 layers of cap sheets. More layers offers increased durability, energy efficiency and weather protection. These roofs are relatively easy to repair. Average lifespan is 25+ years.
Single-Ply: One membrane is used to protect the roof. There are three options available.
-
EPDM, ie. a rubber roof. Lightweight, flexible, affordable, lasting 15-25 years
-
PVC is heat-welded, strong and durable. Lasting 20-30 years
-
TPO, ie. a white roof. Energy-efficient, durable, lasting 15-20 years
Using quality materials is only one part of the longevity equation. Installation and maintenance are equally important. If any one of these parts is compromised, your roof will simply not last as long.
