Replacing a roof is a major investment. We know it comes with big decisions, tight timelines, and the need to trust someone with your home’s safety. That’s why choosing the right contractor is more than just checking a few reviews or comparing prices. It’s about finding the right fit for the job and for you.
Let’s walk through what to look for when hiring a roofing contractor in Alberta. We’ll keep it practical and focused so you can feel confident before signing anything.
Understand the Full Scope of the Project
Firstly, it’s important to understand exactly what a roof replacement involves. In addition, you need to know what the contractor will do from start to finish. This includes removal of old materials, inspection of the structure underneath, installing underlayment, adding new shingles or panels, and ensuring proper ventilation.
We always recommend asking for a detailed scope of work. For instance, your contractor should explain what materials will be used, how long it will take, and what could potentially change the final cost. That is to say, no one likes surprise charges at the end.
Moreover, understanding the stages of a roof replacement helps you ask better questions and set clearer expectations. If you know what each step looks like, you’ll spot shortcuts or missing items early.
Check for Credentials and Local Experience
Secondly, always check for proper licensing and insurance. Above all, never hire someone who cannot provide this paperwork upfront. Roofing is dangerous work, and you don’t want to be liable if something goes wrong on your property.
Beyond credentials, we suggest choosing a contractor with specific experience in Alberta’s climate. In other words, someone who understands what our wind, snow, and hail can do to a roof. The more local the experience, the better they’ll be at recommending durable materials and weather-appropriate techniques.
We’ve seen this firsthand in projects where improper flashing or ventilation led to serious issues later. Consequently, that’s why we always ask contractors about their recent jobs in Alberta and how they’ve handled extreme weather conditions.
Compare Written Estimates — Not Just Prices
Next, get multiple quotes. But more importantly, compare the details of those quotes. For example, one estimate might be lower because it leaves out disposal fees or cheaper underlayment. Similarly, another might seem high but include extra ventilation or longer warranties.
In short, don’t fall into the trap of going with the cheapest bid. Instead, line up each estimate side by side. Look at labour, materials, disposal, and cleanup. This lets you compare apples to apples.
If a quote is vague, that’s a red flag. A good roofing estimate should be clear, complete, and reflect a strong understanding of your home’s needs. That clarity is what we look for every time we vet a new contractor.
Ask About Warranties and Follow-Up Support
A roof isn’t something you want to fix again in five years. Therefore, you need a contractor who stands behind their work. We always ask about two types of warranties: manufacturer warranties on the materials, and workmanship warranties from the contractor.
In some cases, a contractor might offer coverage only if specific conditions are met, like annual inspections. To clarify, that’s not necessarily a bad thing — just something you need to understand from the start.
Additionally, ask about post-installation support. Will they inspect the roof in a year? What happens if there’s a minor leak? Most importantly, how fast do they respond to those issues? It’s easier to trust a contractor who has a clear plan for standing by their work.
Evaluate Communication and Professionalism Early On
Sometimes, how a contractor communicates before the job begins tells you everything. If they’re slow to respond, vague in their answers, or miss appointments, that’s a warning sign. Likewise, if they’re organized, punctual, and clear, that’s a strong indicator of how they’ll manage the project.
We believe good roofing contractors should explain things in plain language. In other words, you shouldn’t need a construction background to understand what’s going on. During the quote process, make note of how easy it is to get updates or ask follow-up questions.
Professionalism includes cleanliness too. For instance, are they clear about how they’ll manage debris and protect your yard during the job? That level of detail often reflects their broader approach to quality.
Visit Past Projects or Ask for References
Reputable contractors will have no problem showing you past work or sharing references. After that, it’s a good idea to visit a recent project if you can. Seeing the final result and talking to a homeowner about their experience gives you real insight.
Ask the reference about the contractor’s timeline, budget accuracy, and any unexpected issues. In the same vein, ask whether they would hire them again. These answers can be more helpful than a dozen online reviews.
As a constructions company in Calgary, we’ve heard from many clients who wished they’d done this step before their first roof replacement. Taking time now to do this homework can save you major stress later.
Check the Contractor’s Safety and Clean-Up Practices
Roofing can be messy and potentially dangerous. That’s why we recommend asking contractors how they’ll protect your property and their team. For example, will they use tarps to cover shrubs or windows? Will they do a magnetic sweep for nails afterward?
Meanwhile, proper safety protocols also protect your liability. Ask about fall protection, equipment use, and how many crew members will be on site at one time.
Clean-up matters just as much as the install. We’ve seen beautiful new roofs surrounded by damaged lawns and stray materials because the contractor didn’t plan for clean-up. Consequently, we always prioritize companies that treat the property with care.
Prioritize Roofing Knowledge and Clear Recommendations
Your contractor should be able to explain why they’re recommending specific materials or methods. For instance, they should know whether your roof is better suited for asphalt shingles, metal panels, or another product based on your budget, climate, and structure.
In addition, they should tell you why they recommend specific brands or layers of underlayment. This level of knowledge builds trust. It also lets you spot sales tactics versus actual expertise.
If they mention attic insulation, ventilation, or ice dam prevention, it’s a sign they’re thinking holistically. A good contractor doesn’t just install a new layer — they assess the full roof system.

Review Timelines and Weather Contingency Plans
In Alberta, weather can change fast. As a result, timelines can shift on short notice. A good roofing contractor will explain how they manage delays and what their backup plans are.
For instance, we’ve worked with teams who use protective covers if weather turns mid-project. Similarly, others schedule extra days into their calendar for padding. Ask how your project will be prioritized if multiple jobs get pushed back due to storms.
It’s also worth asking how long materials take to arrive. Some items might have longer lead times, especially during the busy season. Planning around delivery and crew availability helps you avoid last-minute problems.
Look for a Contractor Willing to Put Everything in Writing
Lastly, everything should be documented — the estimate, the timeline, the scope of work, and the warranty. In short, verbal promises don’t mean much if something goes wrong. A detailed contract keeps both sides protected.
This contract should also include a payment schedule. Above all, never pay the full amount up front. Instead, structure payments around progress milestones. This motivates the contractor to stay on schedule and gives you peace of mind throughout the project.
When contractors hesitate to put things in writing, that’s often a red flag. It’s one of the first things we check before agreeing to any work.
If you’re ready to get started with a trusted, experienced crew, don’t hesitate to contact us today. We’re always happy to answer questions, explain timelines, or provide a clear estimate based on your unique home.
Frequently Asked Questions
How do I know if my roof needs to be replaced rather than repaired?
If you see widespread shingle damage, persistent leaks, or sagging areas, it’s likely time for a full replacement. Age is also a factor — most asphalt roofs last around 20 to 25 years.
What questions should I ask when comparing contractors?
Ask about their licensing, insurance, warranty coverage, past work in Alberta, cleanup practices, and how they handle unexpected delays or costs.
Can I replace my roof during winter in Alberta?
It’s possible but not ideal. Cold weather affects material flexibility and adhesive performance. Most contractors prefer spring through early fall for better conditions.
How long does a roof replacement usually take?
Most jobs take one to three days depending on size, weather, and complexity. However, always ask for a detailed timeline in writing before work begins.
Do I need to leave my home during the roof replacement?
Usually not, but be prepared for noise and vibrations. Pets and small children may be more comfortable staying elsewhere during the loudest phases of the job.
