Roof Inspection When Buying a House in Airdrie: What to Check

Does a home inspector check the roof? They do, but the depth varies enormously, and buyers often assume more than they get. Most general home inspectors in Alberta assess the roof visually from the ground with binoculars, from a ladder at the eaves, or with a drone. Many do not walk the roof at all, for liability reasons, because of pitch or weather, or because their standards of practice do not require it.

That is not a criticism of home inspectors. They are covering the whole house in three or four hours, and their job is to flag visible defects, not to give a roofing opinion. But it means a standard report often says something like "roof appears serviceable, recommend evaluation by a qualified roofer" and leaves it there.

What a ground-level look tends to miss:

• Hail bruising and soft spots that you can only find by hand
• Cracked or rusted flashing behind a chimney or under a skylight curb
• Lifted shingles whose seal strip has failed but which lie flat in calm weather
• Nail pops and exposed fasteners under the tabs
• Granule loss on the upper slopes that cannot be seen from below
• The condition of the attic deck, insulation and ventilation

If the home inspector's report recommends a roofer, take it seriously. It is the inspector telling you they could not see enough to be sure.

A pre-purchase roof inspection by a roofing contractor is a different exercise. Where conditions allow, the roofer walks every slope and puts hands on the shingles. Here is what a thorough one covers, and it doubles as a roof inspection checklist you can hold any inspector to.

• Shingle condition: curling, cracking, cupping, blistering, granule loss and the flexibility of the tabs, slope by slope.
• Hail and wind damage: bruises, fractures in the mat, creased or torn tabs, and the tell-tale dents in soft metals such as vents, flashings and eavestroughs.
• Flashing: chimney, skylight, wall and step flashing, plumbing vents and any satellite dish or solar mounts.
• Valleys and penetrations: the places where water concentrates and most leaks begin.
• Ridge, hips and edges: ridge cap condition, drip edge, and whether ice-and-water membrane is visible at the eaves.
• Eavestroughs and downspouts: slope, attachment, damage and where they discharge. Gutters full of granules are a sign of an ageing roof.
• Skylights: seals, glazing, curb flashing and any condensation staining inside.
• Attic: deck staining, daylight, mould, frost marks, insulation depth, baffles at the eaves, and whether intake and exhaust venting are adequate.
• Estimated age and remaining life: based on shingle style, wear pattern and any permit or paperwork history.
• Written report with photos: findings, priorities, and rough repair or replacement costs.

Our roof inspection service in Airdrie follows this list and provides the photo report. The attic step is the one most often skipped, and it is often the one that changes the verdict, because it shows what the roof has already let through.

Roof inspection cost in the Airdrie area, as of 2026, typically runs $150 to $400 for a paid standalone inspection from an independent inspector or a roofer who charges for reports. Some roofing companies, including Apex Roofing Airdrie, provide the inspection free of charge, on the basis that if work is needed we would like the chance to quote it.

Either way, the buyer generally pays for their own due diligence inspections, and the timing matters. Book it inside your inspection condition period so that the findings can feed into your negotiation before the condition is waived. Most Alberta purchase contracts give a window of several days to two weeks, and roofers in hail season can be busy, so book early.

Set that cost against the stakes. A $300 inspection, or a free one, that finds a roof with two years of life left has just saved you from paying full price for a house that needs $13,000 of work by the second winter.

Roof age and insurance are linked more tightly than most first-time buyers expect. When you apply for home insurance on the new house, the insurer will almost certainly ask the roof's age and material. Many insurers become cautious once a roof passes roughly 20 years. Depending on the company, that can mean a higher premium, an actual cash value limitation on the roof, a requirement for an inspection, or in some cases a reluctance to bind coverage until the roof is replaced.

That matters for closing. Your mortgage lender will require proof of insurance, so a roof that insurers do not like can become a financing problem, not just a maintenance one. The safest course is to get the roof's age and condition established during your conditions period, then check with your broker how your chosen insurer treats a roof of that age before you waive.

Two more things to ask about. First, whether any past hail claims were paid on the property, and whether the roof was actually replaced afterward. Sellers are usually obliged to disclose known defects, but a paid claim that was never spent on the roof is a real thing in Hailstorm Alley. Second, whether the roof has Class 4 impact-resistant shingles, because many Alberta insurers discount premiums for them. Our guide to Class 4 impact-resistant shingles in Alberta explains how to tell and what the discount is worth.

None of this is insurance advice. Policies differ, so confirm the details with your insurer or broker.

Sometimes the listing says "roof 2019" and the seller has the invoice. Often it says nothing. Here is how to narrow the age down before you have even booked an inspection.

• Ask the seller for the reroof invoice or warranty paperwork. A written answer is best.
• Check the property disclosure statement for any mention of roof work or claims.
• Check for a City of Airdrie permit for a reroof; the city can usually search by address.
• Look at the neighbourhood. In areas built in the same few years, such as Windsong, Reunion or Ravenswood, most original roofs were replaced in the same one or two hail years, and the neighbours often know which year.
• Look for mismatched slopes. A newer-looking south slope on an older roof suggests a partial hail repair.
• Ask your insurer or broker whether they hold a roof age from the previous owner's policy.

A roofer can then confirm or correct that estimate from the shingles themselves. Our guide on how long a roof lasts in Alberta explains what to expect from each material once you know the age.

A written roof report with photos is the most useful negotiating document a buyer can have, because it puts a number on something the seller may have been vague about. There are three common ways to use it.

Price reduction. If the roof needs replacing within a few years, ask for a reduction that reflects a fair share of the cost. Sellers rarely agree to the full reroof price on a roof that is still keeping water out, but a meaningful reduction is common when the report is clear.

Seller-completed repairs. For specific defects such as failed flashing, damaged skylights or a valley repair, you can ask the seller to have the work done before possession by a licensed roofer, with the invoice and warranty passed to you. Insist on choosing or approving the contractor; a $200 patch is not the same as a proper repair.

A holdback or credit. Where timing is tight, the parties sometimes agree a holdback from the sale proceeds or a credit at closing so you can arrange the work after possession. Your real estate lawyer or agent can advise on how to structure this.

Whichever route you take, have the report in hand before you waive conditions. After that your leverage is gone. If the report shows hail damage that is still within a claim window, note that any insurance claim would belong to the current owner's policy, not yours, so that conversation has to happen with the seller before closing.

Most roof findings are manageable. A few should make you slow down and think carefully about the whole purchase, or at least about the price.

• A sagging or wavy roofline, which points to deck rot or structural issues under the shingles
• Two or more layers of shingles, which hides the deck and usually means a costlier tear-off
• Widespread attic staining, mould or frost marks, which signal long-term leaks or a serious ventilation problem
• A roof past 20 years on which the seller cannot or will not confirm the age
• Signs of a DIY or unpermitted reroof: inconsistent nailing, missing drip edge, no ice-and-water shield at the eaves
• Evidence of a paid hail claim that was never used for repairs
• Hail bruising across every slope after a known storm, which is a replacement, not a repair

None of these has to kill a deal. Each of them should change the price, or the terms, or both. Our pillar guide to the signs you need a new roof explains how to read them together, and our repair versus replacement guide shows how to put a cost on what you find.

Buyers of newer homes in areas like Cooper's Crossing, Bayside or Kings Heights sometimes skip the roof inspection on the basis that the roof is only a few years old. We would still recommend a look, for two reasons.

First, a young roof is not immune to hail, and a storm between the build and your possession can do real damage that nobody has noticed yet. The August 2026 storm that tracked down the Crossfield to Airdrie corridor hit plenty of homes under five years old. Second, installation quality varies, and defects such as high nailing, missing starter strip or inadequate ventilation show up in the first few years, when they are still a builder warranty or manufacturer warranty matter rather than your bill.

A recently reroofed home deserves the same question in reverse: who did the work, is the workmanship guarantee transferable, and is the manufacturer warranty registered? Our post on roof warranties explained covers what transfers and what does not.

If you are buying in Airdrie, Crossfield, Balzac or north Calgary and the home inspector's report says "recommend evaluation by a roofer", that is your cue. Apex Roofing Airdrie provides free roof inspections with a written photo report you can hand to your agent, your lawyer and your insurer. We book same-week, which matters when your conditions period is ticking.

If the roof does need work, we quote repair and replacement separately and in writing, so you know what to ask for. And if it turns out the roof is sound, we will tell you that too. Our roof repair service and roof replacement service are there when you need them, not before.
