Professional Roof Replacement You Can Trust
When your Calgary roof reaches end of life — whether from hail, age, or both — a proper replacement is one of the most expensive single repairs you'll make on the home. Done right, your new roof lasts 25-30 years and adds resale value. Done wrong, you're patching leaks within 5 years. Our experienced crews strip the old roof to the deck, replace any rotted sheathing, install premium synthetic underlayment + Alberta-code ice & water shield, and re-roof with your choice of GAF Timberline, IKO Cambridge/Dynasty, or CertainTeed Landmark systems.
Common Causes in Calgary Homes
We see these patterns repeatedly across Calgary and area. Knowing the cause helps us respond faster and recommend the right solution.
Hail Damage Beyond Repair
Severe hail (golf-ball-sized or larger) causes shingle damage too widespread for spot repair. Insurance typically approves full replacement once 25%+ of slopes show impact damage. The 2024 Calgary hailstorm triggered tens of thousands of full replacements.
Aging Asphalt Roofs (18-25 Years)
Calgary's UV, freeze-thaw cycles, and Chinook wind events accelerate shingle aging. Most asphalt roofs installed in 2005-2008 are now reaching replacement age. Visible signs: granule loss exposing the mat, curled or cupped shingles, missing tabs after wind events.
Multiple Layers (Code Violation)
Alberta building code allows max two layers of shingles. If your home has a previous re-shingle over the original, the next replacement requires full tear-off. We always recommend tear-off regardless — overlay roofs trap heat and fail prematurely.
Pre-Sale Roof Issues
Calgary real estate inspectors flag any roof under 5 years of remaining life. Replacing before listing recovers most of the cost in sale price and prevents financing complications on the buyer's mortgage.
Switching to Hail-Resistant Class 4 Shingles
Upgrading to Class 4 hail-rated shingles (GAF Timberline HDZ AS, IKO Nordic, CertainTeed Northgate) reduces hail damage risk by 60-70% and may qualify you for insurance premium discounts in Alberta.

Roof Replacement FAQs
Common questions about roof replacement in Calgary, AB.
How much does a roof replacement cost in Calgary?
For a typical Calgary bungalow (1,200-1,500 sq ft roof area), expect CA$8,000-CA$12,000 for architectural asphalt shingles installed. Two-storey homes range CA$12,000-CA$20,000. Premium shingles (Class 4 hail-resistant, designer profiles) add CA$2,000-CA$5,000. Metal roofing runs CA$20,000-CA$40,000+. If hail damage is involved, your insurance typically covers most of the replacement cost minus your deductible.
How long does a roof replacement take?
Most Calgary single-family asphalt replacements complete in 1 day (2 days for larger or complex roofs). We schedule weather-permitting and don't start a tear-off if rain is in the forecast within 24 hours. Metal roof installations take 2-4 days depending on size and complexity.
What's the best shingle for Calgary's climate?
For hail belt protection: Class 4 impact-rated shingles like GAF Timberline HDZ AS (Armour Shield) or IKO Nordic. For best overall performance: GAF Timberline HDZ in the standard line. For premium aesthetics: CertainTeed Presidential Shake or GAF Grand Sequoia. Avoid 3-tab shingles — they don't handle Calgary wind or hail well and they age out 30% faster than architectural.
Do I need permits for a roof replacement in Calgary?
Calgary requires a building permit for any complete roof replacement and most major repairs. We pull the permit as part of our contract — you don't deal with the City directly. Permit cost (typically $250-$500) is included in our quote unless noted.
What about the existing roof — does it need to come off?
Yes, we always recommend full tear-off. Alberta building code allows a maximum of two shingle layers, but even a single overlay roof traps heat, hides deck damage, and fails 5-7 years earlier than a properly-installed tear-off replacement. We don't quote overlay jobs.
What's covered under the lifetime workmanship warranty?
Any installation defect for as long as you own the home — leaks at flashing details, shingle blow-off due to incorrect nailing, ridge cap failures, etc. The shingles themselves carry a separate manufacturer warranty (typically 50 years prorated, with first 10-25 years non-prorated under enhanced warranty programs like GAF Golden Pledge).
