FREQUENTLY ASKED QUESTIONS
The following are some frequently asked questions about standing seam metal roofing systems. If you have a question that isn’t answered here, please contact us today and we will be glad to answer it for you.
Standing Seam is a metal roofing system design with continuous vertical panels that start at the base (where your eavestroughs are) and end at the roof’s ridge or peak. It is called standing seam because each metal panel interlocks with the adjacent metal panel in the form of a prominent raised vertical seam. Better quality systems will have concealed fasteners (clips and screws) so that the roof is as watertight as can be. The seams will be mechanically sealed with a tool called a hand seamer, or, the panel design will “snap-lock” or “click-lock” in place with concealed fasteners.
The cost of a standing seam roof will vary greatly depending on your material choice and the configuration of your roof. If your roof is too steep to walk on (non-walk) or chopped up with turrets, dormers, and hips this can add significantly to your end cost. But to give you a general idea of what the cost could be:
In Ontario, A G90 galvanized steel 24 gauge standing seam metal roof costs on average about 9-12$ CAD per square foot installed. Based on the average, if your roof area was 2000 square feet (20 roofing squares) your total cost would be around $18-24K CAD.
Yes, a standing seam roof can be installed over asphalt shingles. In most cases it is possible to install over up to 2 layers. Installing over shingles saves the cost of stripping and disposal and is better for the environment as it keeps tons of garbage from entering landfill.
