Getting Started

New to dealing with a roofer? These answers cover the first steps, from reaching out to the day someone looks at your roof.

How do I book a free roof inspection?

Fill in the form on this page with your name, address and a short note about what is going on with your roof, or call us. Either way, we get in touch to find a time that suits you. The inspection costs nothing and comes with no obligation. It simply gives you a clear, honest picture of your roof’s condition so you can decide what to do next.

What information should I have ready before I contact you?

A few details make the first conversation far more useful. Roughly how old is the roof, and has it ever been replaced? Where do leaks or stains show up, and do they appear during rain, snowmelt or a chinook? Has there been a recent hailstorm or windstorm? Photos taken from the ground or through a window help too. If you do not know some of these answers, that is completely fine.

Do I need to be home for the inspection?

Not always. Most of the work happens on the roof and around the outside of the house, so many homeowners simply leave a side gate unlocked. That said, being home has real benefits. You can show us the water stain on the ceiling, let us look into the attic, and ask questions on the spot. If you cannot be there, we walk you through what we saw afterwards.

How do I describe a roof problem over the phone?

Start with what you actually see, not what you think the cause is. Say where the problem shows up inside or outside, when it started, and whether it gets worse in certain weather. Mention anything nearby, such as a chimney, skylight, vent or valley where two roof slopes meet. Words like drip, stain, bubbling paint or shingles on the lawn are all helpful. We sort out the cause on site.

What happens after I send a request?

We contact you to confirm the details and book a time for someone to visit. At the visit, we look over the roof, talk through what we found and answer your questions. If work is needed, you receive a written quote that explains what we recommend and why. There is no pressure to decide on the spot, and you are welcome to compare it with other quotes.

Roof Repairs

Repairs are where most roofing questions start. Here is what homeowners ask us most about fixing a roof rather than replacing it.

Can you repair a roof that another company installed?

Yes. Who put the roof on does not change how a leak or a damaged area is fixed. We look at the materials that were used, how they were installed and what failed, then repair it properly. Sometimes the problem traces back to an installation shortcut, such as missing flashing or too few nails, and we explain that plainly so you understand why the repair is needed.

What happens if you find more damage once a repair starts?

We stop and talk to you before doing anything beyond the agreed work. Hidden problems, like a soft section of roof deck under the shingles or rot around an old vent, only become visible once the surface is opened up. We show you what we found, with photos if you are not home, explain the options and let you decide. Nothing extra goes ahead without your approval.

Can you repair one unit on a townhome or shared roof?

Often, yes, but shared roofs come with extra steps. On many townhomes and duplexes, the roof is common property or connects directly to a neighbour’s, so a repair on one side can affect the other. Check with your condo board or property manager before booking, since they may need to approve the work or coordinate it. We are happy to explain our findings to them.

Should I repair my roof before selling my home?

It usually pays to fix known problems before listing. Buyers in Calgary commonly get a home inspection, and an active leak, missing shingles or damaged flashing can lead to price negotiations or a stalled sale. A small repair done beforehand removes that surprise. If the roof is near the end of its life, an honest assessment helps you decide whether to repair, replace or disclose it.

New Roofs and Materials

A new roof is a big decision. These answers cover the practical side of choosing materials and getting through a replacement.

How do I choose a shingle colour I will be happy with?

Look at full-size samples outdoors, in daylight, next to your siding and brick, rather than choosing from a small chip or a screen. Colours often look lighter on a large roof than in hand. Drive past homes nearby with the shades you are considering. Also think long term: a neutral colour tends to suit future exterior changes and appeals to more buyers if you ever sell.

Can I switch from asphalt shingles to a metal roof?

In most cases, yes. Metal can go on most sloped residential roofs in Calgary, and many homeowners switch for its longer lifespan and how it handles snow and hail. The switch involves more than swapping materials, though. Details at the roof edge, ridge, valleys and around chimneys and vents are different, and snow sliding off metal needs planning above doors, walkways and decks.

What happens to the old roofing materials?

Tearing off an old roof creates a lot of debris: shingles, underlayment, old flashing and nails. It is loaded straight into a bin or trailer parked in your driveway or on the street, then hauled away when the job is done. Disposal is part of a complete replacement, so you are not left dealing with it. We let you know where the bin will sit before work starts.

How much noise and dust should I expect during a tear-off?

Plenty of noise, mostly during daytime working hours. Scraping, hammering and nail guns are loud inside the house, especially upstairs, so people who work from home or have young children or pets often plan to be out. Dust and small granules can fall into the attic, and vibration may shake loose items on walls and shelves. Very little of this reaches the main living areas.

How should I prepare my attic and home before a new roof?

Cover anything stored in the attic with old sheets or plastic, or move it out, because dust and debris shake loose during tear-off. Take down pictures, mirrors and fragile items on upper-floor walls. Move vehicles out of the driveway, clear patio furniture and barbecues from around the house, and tell your neighbours. Make sure the crew can reach an outdoor power outlet.

Cost and Paying for Your Roof

Every roof is priced on its own measurements and condition. These answers explain how that pricing works, without guesswork.

How is a roofing estimate put together?

It starts with measuring the roof, which is counted in squares of 100 square feet. Roof area is usually 1.3 to 1.5 times the floor area of the home once pitch and overhangs are included. Next come pitch, the number of layers to remove, access, and details like chimneys, skylights and valleys. A good written quote spells out materials, scope and exactly what is included.

Can the price change after the old roof comes off?

It can, and a clear quote tells you how that is handled. The main unknown is the roof deck, the wood boards under the shingles, which cannot be fully assessed until tear-off. Rotten or soft sections need to be replaced before new roofing goes on. We show you what we found and explain the extra work before it is done, so there are no surprises on the final invoice.

When do I pay, and is a deposit needed?

Payment terms are set out in your written quote, so you know before signing exactly what is due and when. Read that section carefully with any contractor, and ask questions if anything is unclear. As a general rule, be wary of anyone who asks for full payment before work begins, pushes for cash only, or will not put the payment schedule in writing.

Is GST charged on both roof repairs and replacements?

Yes. GST applies to roofing work in Alberta, whether it is a small repair or a complete new roof, and it covers both materials and labour. Alberta has no provincial sales tax, so GST is the only sales tax on the job. When comparing quotes, check whether each one shows the price before or after GST, so you are comparing the same thing.

Can I plan and budget for a new roof ahead of time?

Yes, and it is much easier than facing a replacement after a surprise leak. Asphalt shingles in Calgary usually last about 15 to 20 years, so note your roof’s age and start setting money aside as it approaches that range. A roof inspection gives you a realistic idea of how much life is left. Small repairs in the meantime can help stretch the roof to your planned date.

Hail, Storms and Insurance

Calgary sits in the most active hail belt in Canada. These answers help you respond calmly and sensibly after a storm.

My neighbours are filing hail claims. Should I have my roof checked?

It is worth a look. Hail rarely hits every roof on a street the same way, since roof age, shingle type, slope direction and nearby trees all make a difference. If your neighbours’ roofs were damaged, yours may have been too, even if nothing shows from the ground. An inspection tells you whether there is real damage before you decide whether to contact your insurer.

What photos are most helpful after a hailstorm?

Take them as soon as it is safe, and never climb onto the roof yourself. Photograph hailstones next to a coin or ruler for size, and dents on metal vents, window frames, siding, fences, cars and the barbecue lid. Capture loose granules collected below the roof edge, shingle pieces on the ground and any water stains inside. Photos with dates help show when damage happened.

Can I choose my own roofer for an insurance claim?

Generally, yes. Most home insurance policies let you pick the contractor who does the work, although some insurers suggest preferred companies. Check your own policy wording and ask your insurer if you are unsure. Whoever you choose, get the scope of work in writing and make sure it lines up with what your insurer has approved before the job begins.

What if the insurer’s scope seems to miss some damage?

Raise it with your insurer, supported by documentation. Claim scopes are sometimes written from a quick look, and items like damaged vents, flashing or a second slope can be missed. Ask for a copy of the scope, compare it with the inspection findings and photos, and send your insurer the details in writing. Keep copies of everything you send and receive during the claim.

A contractor wants me to sign right after a storm. Should I?

Slow down before signing anything. After big hailstorms, out-of-town crews often go door to door, and some ask homeowners to sign papers that commit them to that company or hand over part of the claim. Read every page, and never sign under pressure on your doorstep. Ask for a local address, and take time to get a second opinion and check your policy.

Calgary Weather and Timing

Calgary’s climate shapes when and how roofing gets done. Here is how the seasons affect your roof and your schedule.

Should I wait until spring for a roof replacement?

That depends on the roof’s condition. If it is sound and just ageing, waiting for warmer weather is reasonable, and booking early in the year helps you beat the summer rush, when roofers are often booked four to six weeks out. If the roof is actively leaking, do not wait. A repair or temporary fix can protect the house until a full replacement can be scheduled.

How do chinooks affect my roof?

Chinooks can push Calgary above freezing, sometimes past 10°C, for days in the middle of winter. That rapid warming melts roof snow, and when temperatures drop again the water refreezes at the cold eaves, feeding ice dams. Repeated swings also make materials expand and contract. On the plus side, chinooks create useful windows for winter repairs once temperatures climb above about 5°C.

When should I book fall roofing work in Calgary?

Aim to book by mid-September. Snow can arrive in Calgary as early as the third week of September and usually settles in by late October or early November. A full replacement needs three to five dry days, and shingle sealant strips bond best above about 5°C. Booking early gives your job a better chance of landing in a stretch of good weather before winter.

Does the sun at Calgary’s altitude affect my roof?

Yes. Calgary sits more than a kilometre above sea level, where sunlight carries more ultraviolet energy, and the city gets a lot of sunny days. UV slowly breaks down the asphalt in shingles, making them brittle and causing granules to loosen. Combined with hail, chinook swings and freeze-thaw cycles, that is part of why asphalt shingles here usually last about 15 to 20 years.

Working With Rock Roofing

How we work matters as much as the materials we install. Here is what to expect when you hire Rock Roofing Calgary.

How do you decide whether to recommend a repair or a replacement?

We base it on the roof in front of us, not on what is bigger. If the damage is limited and the rest of the roof has good years left, we recommend a repair. If the shingles are worn out across the roof or problems keep coming back, we explain why replacement is the better use of your money. You get the reasoning, with photos, so you can decide.

How do you clean up after a roofing job?

Cleanup is part of the job, not an afterthought. Debris goes into a bin as work progresses rather than piling up on the lawn. At the end, we clear the roof edges, walkways, driveway and yard, and run a magnetic nail sweep across the grass and hard surfaces to pick up stray nails. We want your property to look the way it did before we arrived.

How will you keep me updated during the job?

You know the plan before we start: the expected start day, what happens each day, and who to talk to with questions. If weather forces a delay, we tell you rather than leaving you guessing. If we uncover something unexpected, such as a damaged section of deck, we contact you before going further. When the work is finished, we walk you through what was done.

Which parts of Calgary do you work in?

We work with homeowners across all four quadrants of Calgary: northwest, northeast, southwest and southeast. That covers everything from older inner-city neighbourhoods with decades-old roofs to newer suburban communities hit by recent hailstorms. Roofs in different parts of the city face different issues, from mature trees dropping debris to wide-open exposure to wind, and we take those local conditions into account.
