We get these questions every week — on the phone, on job sites, standing in someone’s driveway looking up at their roof. So we figured we’d write them all down and give you straight answers. No sales pitch, no fluff. Just what we’ve learned from years of tearing off old roofs and putting on new ones across Calgary. If your question isn’t here, call us and we’ll answer that one too!
Roof Replacement
1. How much does it cost to replace a roof in Calgary?
Most Calgary homeowners pay between $7,000 and $19,000 for a full roof replacement, depending on roof size, pitch, and complexity. For an average asphalt shingle roof, a bungalow typically costs $7,000–13,000 and a two-storey home runs $10,000–19,000. Material choices, decking condition, and the number of layers to tear off also affect the final price.
2. How often should a roof be replaced in Calgary?
Most asphalt shingle roofs in Calgary last 15–25 years, though hail, Chinooks, and UV exposure can shorten that lifespan. Most of the roofs we replace are 18–25 years old—that’s when shingles start curling, losing granules, or leaking. We recommend getting a professional roof inspection around the 15-year mark so you know where things stand.
3. What is the most expensive part of replacing a roof?
Labour and materials make up the bulk of the cost, but the most common hidden expense is replacing damaged plywood or decking discovered after the old shingles come off. Steep or complex rooflines also drive labour costs up. Homeowners are often surprised by decking damage because it’s invisible until the tear-off.
4. What do they do when they replace a roof?
The crew strips all old shingles and underlayment, inspects the decking for rot or damage, and replaces any bad plywood. Then they install ice-and-water shield, new underlayment, and lay the new shingles. Flashings around vents, chimneys, and edges are replaced as well. Most full replacements take one to two days to complete.
5. What is the difference between roof replacement and reroofing?
Reroofing means laying new shingles over the existing layer, while a full replacement involves tearing everything off down to the decking. Calgary building code allows up to two layers. We usually recommend a full tear-off so we can inspect what’s going on underneath, but if the existing roof is still solid, reroofing can be an option.
6. What is the cheapest way to replace a roof?
Durable standard asphalt shingles are the most budget-friendly option. We recommend addressing the most critical repairs first to keep the roof safe, then scheduling the work in fall or early winter when demand is lower. Going too cheap can cost more long-term if you’re replacing again in 15 years.
7. What is the cheapest time of year to get a new roof?
Late fall and early winter are the off-season for Calgary roofers, so you’ll often find better pricing and faster scheduling. Spring and summer are peak season with higher demand and sometimes higher labour rates. At Vami Roof Repair, we offer off-season pricing and discounts during slower months to help homeowners save money.
8. Can you claim a new roof on your taxes in Calgary?
A standard roof replacement isn’t tax-deductible for Canadian homeowners. The City of Calgary previously offered a $3,000 Resilient Roofing Rebate for Class 4 impact-resistant shingles, but that program ended in 2024. There may be federal energy-efficiency grants worth looking into. We help our clients with any available paperwork to make the process as smooth as possible.
9. Should I replace my roof if it’s not leaking?
Not leaking doesn’t mean the roof is in good shape. If your roof is 20+ years old or has visible damage like curling shingles, missing granules, or sagging, it’s worth getting an inspection. Waiting until it leaks often means dealing with interior water damage, which is a much bigger expense. We recommend a roof inspection once a roof reaches that age.
10. Can you repair a roof without replacing it?
If the damage is isolated—a few missing shingles, minor flashing issues, or a small leak—repairs can work well without a full replacement. During our inspection, if we see the roof still has a few good years left, we do repairs only. But if the roof can’t go any longer, we recommend full replacement.
11. What is the typical warranty for a new roof?
Most shingle manufacturers offer 25–50 year material warranties, and some premium products carry lifetime warranties. Your roofing contractor should also provide a separate workmanship warranty. At Vami Roof Repair, we offer a 15–20 year workmanship warranty on our labour and pass along the full manufacturer warranty on roofing materials.
Roof Repair
12. How much should it cost to fix a roof?
Roof repairs in Calgary typically cost $700–$3,000, depending on what needs to be done. Replacing a handful of blown-off shingles or resealing flashing is on the lower end, while more involved structural repairs cost more. The scope of the damage determines the final price, so a proper inspection is the first step.
13. What is the most common roof repair?
Replacing damaged or missing shingles after a hailstorm is by far the most common roof repair in Calgary. We get many calls to change shingles damaged by hail—it’s the number one repair request. Flashing repairs around vents and chimneys are a close second.
14. What are signs I need a roof leak repair?
Water stains on your ceiling, peeling paint, damp spots in the attic, or visible daylight through the roof boards all point to a leak. From the outside, check for missing or cracked shingles, damaged flashing, or granules collecting in your gutters. Also look to see if any shingles or air vents have blown away after a storm.
15. What is the best time of year for roof repair?
Late spring through early fall is ideal because warmer temperatures help shingles seal properly. That said, emergency repairs can’t wait. At Vami Roof Repair, we do repairs year-round, including emergency work. When a customer calls, we need to be there for them.
16. What is the cheapest way to repair a roof?
Catching problems early is the cheapest approach. A small repair today can prevent a full replacement next year. We recommend homeowners check their roof once in a while to see what’s going on—patching a few shingles or resealing flashing is straightforward and affordable when done promptly.
17. Can you repair just a section of a roof?
Yes, if the damage is localized. We assess the age of the roof, the extent of the damage, and the overall condition of the shingles and decking. If the problem is contained to one area and the rest of the roof still has good life left, a partial repair makes sense.
18. Can I repair a roof leak myself?
We’d strongly recommend against it. Working on a roof is dangerous, and an improper DIY repair can void your warranty and cause more damage. We’ve seen many repairs where the job wasn’t done properly, so we had to start from the beginning—that’s extra work and extra money. Keep it professional.
19. Will a roof leak with one tile missing?
It can, especially in Calgary where we get heavy rain, wind-driven snow, and freeze-thaw cycles. Even one missing shingle exposes the underlayment to the elements, and once that degrades, water reaches the decking. It’s a small fix now but a big problem if left alone.
20. How to find a roof leak with no attic?
Without attic access, start by looking for water stains on your ceilings and tracing them back as far as you can. Outside, check for damaged shingles, cracked flashing, and pooling water. We first check the leak from inside, then go up on the roof to locate it. If it’s hard to find, checking during or right after rain helps because the leak is more visible.
21. Who is responsible for leaking roofs?
If you own the home, roof maintenance and repairs are your responsibility. For renters, the landlord is typically responsible for structural repairs including the roof. If the leak was caused by a storm, your home insurance may cover the repair—file a claim promptly. We help document the damage and provide the information homeowners need for their claim.
Hail Damage
22. Does insurance cover hail damage in Alberta?
Yes, most standard home insurance policies in Alberta cover sudden hail damage to your roof, siding, and windows. Coverage varies—some policies pay full replacement cost while others use actual cash value, which factors in depreciation. We’ve worked with many insurance adjusters in Calgary and provide clear documentation, photos, and estimates to help make the claim process smoother for homeowners.
23. Am I covered for hail damage?
Most likely yes, if you have standard home insurance. Full replacement policies cover the cost regardless of roof age, while actual cash value policies reduce the payout based on depreciation. Call your insurer before starting repairs. We help our clients all the way through the insurance process.
24. Where was hail damage in Calgary?
Calgary sits in what’s known as Hailstorm Alley—one of the most hail-prone regions in Canada. The 2024 hailstorm caused nearly $2.8 billion in insured damages, and the 2020 storm generated over 70,000 claims. We’ve received many calls from the NW area, which seemed to be the hardest hit, though we get calls from all over the city.
25. Has the cost of hailstorm damage increased in Calgary?
Dramatically. Alberta accounted for roughly $4.1 billion in insured losses in recent years, with over half of the $11 billion in claims from the past two decades occurring in just the last five years. We’ve noticed material and labour costs change over time, so we adjust our quotes accordingly to reflect current market prices.
Flat Roofing
26. What is the average lifespan of a flat roof?
A well-maintained flat roof typically lasts 20–30 years, depending on the membrane material and maintenance. For Calgary’s climate, we often recommend SBS modified bitumen (torch-on) because it handles extreme cold, snow, and freeze-thaw cycles very well. In our experience, a properly installed flat roof typically lasts 25–30 years.
27. Is it better to repair or replace a flat roof?
For small, isolated issues like a puncture or cracked seam, repair is usually the smart move. We recommend replacement when the roof is near end of life, has widespread damage, or when repair costs would exceed 30–40% of a full replacement. Ongoing patch jobs on an old flat roof add up fast.
28. Can a flat roof be repaired?
Yes. Minor cracks, small punctures, and seam separations can be patched. We first inspect for leaks, ponding water, and damaged membrane, then repair or replace only the affected area when possible. Catching problems early is key—standing water on a flat roof accelerates damage quickly.
29. How to repair a flat roof without replacing it?
Small leaks and cracks can be sealed with fiberglass mesh, membrane patches, and roofing sealant. For larger areas, a roofer can apply a new coating or patch over the damaged section. Regular inspections—especially after Calgary’s heavy storms—help catch issues before they require full replacement.
Skylight Repair
30. How much does it cost to get a skylight fixed?
Skylight repair costs in Calgary depend on the scope of work. Simple jobs like resealing the step flashing don’t cost much, while more involved repairs like replacing damaged flashing or weatherstripping run higher. If the skylight needs full replacement, expect $1,500–$4,000+ depending on size and accessibility.
31. Can a skylight be repaired?
In most cases, yes. Leaks caused by worn seals or damaged flashing are very repairable. In our experience, about 70–80% of skylight calls are repairs, while 20–30% require full replacement depending on age and damage. If the skylight is 20+ years old with cracked glass or a deteriorating frame, replacement is usually smarter.
32. What is the most typical skylight problem?
Leaking due to flashing failure is the number one issue. Calgary’s freeze-thaw cycles and Chinook temperature swings cause flashing to expand and contract, eventually pulling away from the shingles. Sometimes the original installer didn’t seal them properly or used too many nails, which can cause premature failure.
33. Why is my skylight leaking in heavy rain?
Heavy rain exposes flashing or seal failures that aren’t obvious in light rain. Degraded sealant, damaged flashing, or clogged weep holes are the usual culprits. We’ve responded to emergency leak calls on rainy days—we show up, make it safe for the moment, and then complete the full repair once the rain stops.
34. How much does it cost to repair flashing around a skylight?
Skylight flashing repairs typically cost $300–$800 in Calgary, depending on the extent of the damage and the roof’s accessibility. If the flashing is severely deteriorated, a full re-flash may be needed as part of a skylight replacement. This is a repair we handle regularly and take great care with.
35. Do skylights need to be resealed?
Yes. Over time the sealant dries out and cracks due to UV exposure and temperature changes. Resealing every 5–10 years is a good rule of thumb and a relatively inexpensive way to prevent leaks. At Vami Roof Repair, we offer skylight resealing as a regular service.
36. What is the average lifespan of a skylight?
A well-installed skylight typically lasts 15–20 years. After that, seals, flashing, and glazing start to fail. If you’re replacing your roof and the skylights are 15+ years old, we recommend replacing them at the same time—it saves a lot of money compared to doing them separately.
37. Can I replace skylights without replacing the roof?
Yes, skylights can be replaced independently. However, if your roof is also nearing end of life, doing both at once saves on labour and ensures everything is properly sealed and integrated. Bundling the two together is almost always the more cost-effective option.
38. Do roofers fit skylights?
Yes. Since the skylight ties directly into the roofing system through flashing and underlayment, it makes sense to have your roofer handle it. Vami Roof Repair installs new skylights and does repairs—we handle both, so there’s no need for a separate contractor.
Shingles, Materials & Calgary-Specific
39. What is the best roofing material for Calgary?
For most Calgary homes, architectural asphalt shingles offer the best balance of durability, cost, and performance. We work with Owens Corning—it’s a very good shingle with longer endurance than many alternatives. On every replacement, we also replace all air vents, goosenecks, and plumbing boots for a complete system.
40. What is the difference between Class 3 and Class 4 shingles in Calgary?
Class 4 shingles pass a more rigorous impact test—they withstand a 2-inch steel ball dropped from 20 feet. Class 3 offers some resistance but doesn’t meet that top standard. We highly recommend Class 4 for Calgary. It costs a bit more, but you know your roof is going to hold up for the next 20–25 years.
41. What is the roof rebate in Calgary?
The City of Calgary’s Resilient Roofing Rebate Program offered homeowners $3,000 for installing Class 4 impact-resistant shingles. Many Calgary homeowners took advantage of the program, but it ended in 2024 and isn’t currently running again. There are some rumours about the possibility of something similar returning—check calgary.ca/hail for updates.
42. What is the average lifespan of a roof?
In Calgary, a standard asphalt shingle roof typically lasts 15–25 years, and premium impact-resistant shingles can push that closer to 30 years with proper maintenance. The longest-lasting roof we’ve installed is 17 years old now—we recently checked on it, and it’s going to be good for at least another 10 years.
43. Is it bad to put a second layer of shingles on a roof?
Calgary building code allows up to two layers, but most roofers recommend against it—including us. A second layer adds weight, traps heat, and hides potential decking damage underneath. We prefer to tear off all the shingles so we can inspect for damaged plywood and replace it now, before it’s too late.
44. How much more expensive is a Class 4 roof?
Class 4 impact-resistant shingles typically add $2,000–$3,000 to the total job compared to standard architectural shingles. Many insurers offer premium discounts for Class 4 roofs, and you’re far less likely to need a hail damage claim—so the investment often pays for itself over time.
45. How to pick the best roofer?
Look for a roofer who is licensed, insured, and a member of a recognized industry association. Check Google reviews and make sure they provide a written warranty on materials and workmanship. Ask about the full scope of work, what’s included in the price, material brands, warranties, and whether they can assist with insurance paperwork.
46. Which roof type adds the most value to a home?
Architectural asphalt shingles offer the best return on investment for most Calgary homes—they improve curb appeal and typically recoup 60–70% of the cost at resale. Class 4 impact-resistant shingles add even more value in Calgary because buyers know they’re getting hail protection and potential insurance savings.
