Roof Replacement in Calgary, AB

When a roof is past repairing, a full replacement protects your home for the next 25 years or more. Calgary roofers handle tear-off, decking repairs, underlayment, ventilation and clean-up.

A proper replacement is more than new shingles. It includes removing the old layers, replacing soft decking, installing ice-and-water shield at the eaves and valleys, synthetic underlayment, new drip edge and flashing, and balanced attic ventilation so the roof lasts.

Ask for a written quote that lists the shingle line, underlayment, ventilation and warranty, so you can compare roofers fairly.

Signs you need roof replacement

Roof Replacement questions

Can new shingles go over the old ones?

Some codes allow one overlay, but most Calgary roofers recommend a full tear-off so they can inspect the decking and the warranty stays valid.

What warranty comes with a new roof?

Shingle manufacturers offer material warranties of 25 years to lifetime, and roofers usually add their own workmanship warranty. Get both in writing.

Do I need to be home during the replacement?

No, but expect noise for a day or two. Move cars out of the driveway and cover items in the attic.
