It would depend on a few factors:
- Expected lifetime for roof
- Roof Type (Flat or Sloped)
- Aesthetics ( Style/Appearance)
For sloped roof you have wide range to choose from including cedar shakes, asphalt shingles, clay/concrete tiles, and metal.
If 20-30 years is a sufficient lifetime for a roof there are a variety of asphalt shingles to choose from in different shapes, styles, thicknesses and colour. They are cost effective as well.
Cedar shakes are the more luxurious choice costing 1.5-2.5 times the cost compared to asphalt. Many homeowners are now converting from cedar to asphalt but if you choose to remain with cedar you will stand out as the unique household on the block.
For a longer roof life of 30+ years metal and concrete tile roofs are the route to go. They may be more expensive than your conventional roof but if you are looking for a lifetime roof, go with metal or concrete tiles.
For flat roofs you can choose from EDPM rubber, TPO, PVC and torch-on SBS.
Torch-on SBS is the standard product used in the Canadian marketplace for flat commercial and residential roofs. It’s a cost effectivecost-effective system, easy to repair and usually lasts between 15-25 yearsa good number of years usually 15-25 years.
PVC is a more environmentally friendly product than SBS. The life expectancy of a PVC roof is longer than most torch-on SBS roofs. The material and labor coverage ranges from 15-25 years. PVC is more expensive than an SBS roof but comes with added value in lifetime and warranty.
