Shingle Roof Replacement and Shingle Repair in Calgary

Shingle roof replacement in Calgary

A shingle roof replacement from us is a full tear off, never a second layer over the old one. We strip the roof to the deck so the plywood can be inspected, replace any damaged wood, then build the new roof from the edge up: metal drip edge, ice and water shield in the valleys and along the eaves, underlayment, and new asphalt shingles fastened in a 6-nail pattern.

• How long it takes. Most Calgary homes are done in one to two days, weather permitting, and we do not leave a roof open overnight.
• What the quote costs. Nothing. We measure and inspect the roof and send a written, itemized quote.
• Warranty. Every full roof replacement carries our 10-year workmanship warranty, on top of the manufacturer's warranty on the materials.

Shingle repair in Calgary

Most roof leaks start with something small: a few shingles lifted or blown off by wind, a cracked vent collar, lifted flashing or nails that have backed out. A shingle repair replaces the damaged shingles, fixes what let the water in, and leaves the rest of the roof alone.

• What the visit costs. A repair starts with a $160 diagnostic inspection, credited in full to the repair when you go ahead. A leak has to be traced on the roof before it can be priced.
• What the repair costs. Our minimum charge for a roof repair is $860. You get an exact written price after the inspection, before any work starts.
• Emergencies. Our emergency line is open 24/7, and for an emergency we are usually on site in 2 to 4 hours.

Repair or replace: what decides it

We look at the whole roof before we answer, and we tell you when a repair is enough. These are the patterns that decide it:

• One leak in one spot, on a roof with life left: repair it.
• A few shingles missing after a windstorm, the rest lying flat: repair it.
• Leaks in two different rooms: the underlayment is finished, not just the shingles. That is a replacement.
• Granules filling your eavestroughs, shingles curling or cupping: the shingles are aging out everywhere, and a patch will not stop the next leak.
• Hail bruising across several slopes: usually a replacement, often through insurance.

Our guide on whether to repair or replace a roof in Calgary goes through the decision in more detail.

Hail, insurance and Class 4 shingles in Calgary

Hail is the reason shingle choice matters in Calgary. The Insurance Bureau of Canada puts the August 5, 2024 Calgary hailstorm at $3 billion in insured losses, and reported that almost one in five homes in the city was affected.

• If hail has hit your roof. The City of Calgary says to contact your home insurance provider before you do any repair work. The Insurance Bureau of Canada says standard home policies cover damage caused by hail or wind, and that pre-existing damage is not covered. Our hail inspections are free, and we photograph and document the damage so you have clear evidence for your insurer. See hail damage roof repair and roof insurance claims in Calgary.
• What Class 4 means. Class 4 is the highest impact rating a shingle can carry. In the test, as the manufacturer Malarkey describes it, a Class 4 shingle takes a 2 inch steel ball dropped from 20 feet without showing visible cracks on the back.
• Insurance discounts. Malarkey notes that highly rated shingles often qualify for insurance discounts. That is your insurer's decision, so ask your broker what a Class 4 roof does to your premium before you choose a shingle.
• Rebates. The City of Calgary's Resilient Roofing Rebate Program paid $3,000 toward Class 4 roofs after the June 2020 hailstorm. The City reports that it ended in May 2022, after 1,600 rebates.

Do you need a permit to replace shingles in Calgary?

No. The City of Calgary lists roofing materials among the things you can replace or repair without a permit. Changing from shingles to clay roofing material is the exception it names, and that needs a building permit.

The shingles we install

We install architectural and Class 4 impact-resistant asphalt shingles, including Malarkey and GAF.

Malarkey makes its shingles with SBS polymer modified asphalt, which it calls rubberized: the rubber polymers add flexibility and help the shingle absorb hail impact. Its Vista shingle is listed with a Class 4 impact rating, a limited lifetime manufacturer warranty and an enhanced wind warranty of up to 130 mph (209 km/h). Those are the manufacturer's terms and they come with conditions, so ask us for the warranty document for the exact shingle in your quote. Malarkey also states that its extended warranties are available from Malarkey Certified Contractors, so ask any roofer, including us, which manufacturer programs they are enrolled in.

What a shingle roof costs

For an average 2,000 sq. ft. Calgary home, a new asphalt shingle roof typically runs $9,000 to $14,000. The size of the roof, the pitch, the shingle you choose and any rotten decking found once the old shingles are off all move the price, which is why we measure before we quote. Our Calgary roof replacement cost guide goes through each of those.

A shingle repair is priced after the diagnostic. Our minimum charge for a roof repair is $860, and the $160 diagnostic comes off the bill when you go ahead.
