What Lethbridge homeowners say
“Awesome service and new roof that looked like it is now armour plated.”
“Recycling of their scrap metal. Overall we are pleased.”
“There's a little joint on the top of the roof that they didn't quite do right.”
“We didn't realize the installer was coming that day because it was not confirmed. Other than that we were happy.”
“The installation crew left our gate open at the end of the day after they cleaned up and our dog escaped.”
“It was a pleasure working with the Interlock Roofing crew and staff. Not only did they finish the job in a timely manner but they completed the job almost two months earlier than was scheduled, allowing us to go on our scheduled vacation.”
Roofing in Lethbridge: what to plan for
Hail: what the rating covers, and what it doesn't
The Calgary to Red Deer corridor is one of the most hail-prone parts of Canada, so hail is usually the first question we are asked. Interlock's Slate, Shake, Cedar Shingle and Mediterranean Tile aluminum panels carry a UL 2218 Class 4 impact rating, listed by Intertek under Delta Building Products. No roof is hail-proof: very large hail can dent metal, the material warranty excludes hail larger than 38 mm (1.5 in), and hail damage is a matter for your home insurance. Ask your insurer how they treat an impact-rated roof; we can give you the documents.
Chinooks, freeze-thaw and wind
In southern Alberta a chinook can lift a winter day from well below freezing to above it within hours, then the cold returns and the meltwater freezes again. That cycle loosens asphalt granules, and chinook gusts work at shingle tabs. An Interlock roof has no granules to lose and no tabs to lift: the panels lock to each other on all four sides with the fasteners concealed, and wind resistance is warranted to 193 km/h (120 mph) installed to manufacturer specification.
Bungalows, infills and older homes
Inner-city bungalows, 1970s split-levels and new infills all take the same system. Interlock's Slate, Cedar Shingle and Shake profiles give the look of stone or wood at roughly 2 to 3.5 kg per square metre, a fraction of concrete tile or natural slate. Every profile needs a minimum 3/12 roof slope, and we confirm yours at the consultation.
Acreages, farms and foothills properties
On an acreage or farm the house, garage, shop and barn can share one profile and colour. In the foothills and the Bow Valley, where forest comes close to the house, we can quote the Class A Fire Rated Available assembly, which uses two layers of GAF VersaShield® over 12 mm (15/32-inch) plywood under the panels. Snow guards over entries, decks and the driveway are planned at the quote.
Condo and townhouse complexes
Under Alberta's Condominium Property Act the board of the condominium corporation usually decides on the roof, often with a reserve fund study in hand. We give boards one profile and colour across every building, the product documents they ask for, and both warranties in writing.
A Calgary company, with its own crews
We install every roof ourselves, from our office on 46 Ave SE in Calgary. The manufacturer's Guardian Lifetime Limited Material Warranty and our 10 Year Limited Labour Warranty come with the roof, and the service team that answers for it after the install is here in Alberta.
