Metal Roofing
in Calgary

This is the most common concern homeowners raise — and the answer is: not in a properly installed system. Metal roofing installed over solid decking with a full underlayment layer is no louder than asphalt shingles during rain. The deck and insulation absorb the sound. Older metal roofing on open purlins (common on barns and sheds) is the noisy type. A residential standing seam or stone-coated steel system on a house will not produce noticeable sound differences.

Quality steel and aluminum roofing systems carry manufacturer warranties of 40–70 years, and many products from the 1970s are still performing today. Calgary's climate — intense UV, freeze-thaw cycles, and hail — is well within the design tolerances of modern metal roofing. Galvalume steel and Kynar 500 painted finishes are engineered for extreme weather. With minimal maintenance (periodic cleaning, checking sealants on penetrations), metal roofing in Calgary can realistically outlast the mortgage on your home.

Metal roofing typically costs 2–3 times more upfront than architectural asphalt shingles. For a typical Calgary bungalow, expect $18,000–$35,000 installed for standing seam versus $8,000–$16,000 for architectural shingles. However, when you factor in a 40–70 year lifespan versus 25–35 years for shingles, the lifetime cost of metal roofing is often equal to or less than replacing shingles twice. It also adds measurable resale value and can reduce homeowner insurance premiums in some cases.

Metal roofing — particularly stone-coated steel and Class 4 rated standing seam panels — offers outstanding hail resistance. Stone-coated steel typically achieves Class 4 UL 2218 ratings, the highest available. Unlike asphalt shingles, metal does not granulate or crack from hail impacts. You may see minor cosmetic denting from extreme hail events, but the waterproofing integrity of the roof is typically unaffected. Many Alberta insurers offer premium discounts for Class 4 impact-rated metal roofing.

In many cases, yes — standing seam and metal panel systems can be installed over one existing layer of asphalt shingles using a batten or furring strip system. This eliminates tear-off costs and disposal fees, saving $1,500–$3,000 on a typical Calgary home. However, we always inspect the decking condition first. If the existing deck has rot, moisture damage, or structural issues, tear-off is required before installation. We will give you an honest assessment during the estimate visit.
