Mississauga Roofing Company – Roof Replacement & Roofing Specialists
Above It All Roofing has been replacing roofs in Mississauga since 2000. In that time, we’ve completed over 3,200 projects across the city from Port Credit to Churchill Meadows and earned a Toronto Star Readers’ Choice Diamond Award two years running.
Your roof might be the single most important investment you’ll ever make in your home, and it’s probably the one you think about least. It sits above everything that matters: your family, your belongings, decades of memories, and one of your largest financial assets.
Year after year, it takes whatever Mississauga throws at it: heavy snow one month, driving rain the next, then a stretch of freeze-thaw weather that would wear down almost anything. Most Mississauga homeowners don’t give their roof a second thought until something forces the issue.
Maybe you’ve noticed shingles starting to curl, granules piling up in your eavestroughs, or a leak after the last big storm. Maybe you’re buying a home, getting ready to sell one, or simply trying to figure out if another repair is worth it.
Whatever brought you here, you’re probably asking some version of the same questions we hear from Mississauga homeowners nearly every week:
● Does my roof actually need to be replaced?
● Can it still be repaired?
● Which roofing company in Mississauga can I genuinely trust?
● What should a quality roof replacement in Mississauga include?
● How do I know I’m making the right call?
At Above It All Roofing, we believe choosing a roofer shouldn’t be a gamble. Since 2000, we’ve helped Mississauga homeowners make confident roofing decisions backed by honest advice, real craftsmanship, premium materials, and a customer experience built on communication and follow-through.
Whether you’re weighing a full roof replacement, sorting out storm damage, planning ahead before a small problem grows into a big one, or you just want an experienced set of eyes on your roof’s condition, our team is here to help you make the right decision for your home, not the easiest sale for us. Because protecting a home starts with choosing a roofer you can actually trust.
Why Mississauga Homeowners Choose Above It All Roofing
Above It All Roofing is a Toronto Star Readers’ Choice Diamond Award winner for 2021 and 2022, voted by homeowners across Mississauga and the GTA. We hold a CertainTeed Select ShingleMaster credential, the highest certification level CertainTeed awards to roofing contractors.
At Above It All Roofing, we’ve spent more than 25 years earning that trust one project at a time because quality roofing was never really about installing shingles. It’s about protecting a home correctly from day one. It’s refusing to cut a corner just because nobody would see it. And it’s treating every job site the way we’d want our own home treated. That work ethic shapes every decision we make.
One of the biggest misconceptions in this industry is that every inspection should end in a sale. We don’t operate that way. If your roof still has years of reliable life left, we’ll tell you. If a targeted repair makes more sense financially than a full replacement, we’ll explain your options honestly. And if repeated repairs are starting to cost more than replacing an aging roof outright, we’ll be just as transparent about that.
Roofing is one of those trades where hands-on experience is a must. After thousands of completed projects across Mississauga and the GTA, patterns start to emerge. You learn which flashing details prevent leaks years down the road. You spot warning signs most homeowners walk right past. You understand how different materials hold up after a decade of Ontario winters, and you know exactly where shortcuts tend to get taken, and what they cost later.
Homeowners deserve more than a contractor who shows up and installs shingles. They deserve someone who returns calls, shows up when promised, and communicates clearly throughout. Someone who looks after the landscaping, keeps the job site organized, and respects the property they’re working on.

Workmanship Warranty On Every Roofing Job
Every roof we install is backed by two layers of protection: our own workmanship warranty and the applicable manufacturer product warranty.
Our workmanship warranty covers defects in installation, flashing, fastening, underlayment, and all work performed by our crew. If something fails because of how the roof was installed, we come back and fix it. No arguments, no fees.
Manufacturer warranties depend on the product and certification level. Because we hold a CertainTeed Select ShingleMaster credential, the highest level CertainTeed awards, we are authorized to offer the SureStart PLUS 5-Star warranty on qualifying CertainTeed products. That covers 25 years of workmanship and 50 years of non-prorated materials coverage. Most roofing contractors in Mississauga cannot offer this warranty because they don’t hold the certification required to issue it.
For GAF products, our installer certification allows us to register your roof for valid GAF warranty coverage. For flat roofing, Elevate (formerly Firestone) warranty coverage applies to membrane systems we install under their certified installer program.
All warranty documentation, both our workmanship warranty and the applicable manufacturer warranty, is provided to you in writing within 48 hours of project completion. If you ever need to make a claim, we walk you through the process.

Roof Replacement Mississauga
A roof replacement is one of the most significant home investments you’ll make, and in Mississauga, where winters are punishing and freeze-thaw cycles stress materials year after year, getting it right the first time matters enormously.
Most Mississauga homes have asphalt shingle roofs that last 20–25 years under normal conditions. As a roof approaches or passes that threshold, repairs become more frequent, energy costs start climbing, and the risk of a serious leak grows with every season. At some point, another repair simply isn’t the better investment. A full roof replacement in Mississauga typically makes more financial sense when repair costs are stacking up, when water has started finding its way inside, or when the shingles are brittle, curling, or missing in multiple areas.
What’s included in a full roof replacement in Mississauga:
A properly installed roofing system includes tear-off and disposal of all existing materials, replacement of any damaged decking, ice and water shield along all eaves and valleys, synthetic underlayment across the full deck, new shingles installed to manufacturer specifications, properly sealed and counter-flashed penetrations at chimneys and skylights, and ridge ventilation to protect the system from the inside out. Every one of these components affects how long your new roof lasts; most homeowners only find out they were skipped when problems show up two or three winters later.
How much does roof replacement cost in Mississauga?
For a typical Mississauga detached home, a full asphalt shingle roof replacement generally ranges from $8,000 to $18,000 depending on roof size, pitch, the shingle line selected, and the condition of the existing deck. Metal roof replacement runs higher. We provide written, itemized quotes so you know exactly what’s included before any work begins- no surprises on completion day.
How Long Does Roof Replacement Take?
Most Mississauga homes are completed in a single day. Larger or more complex roofs may take two days. We remove all old materials, install the full system, and clean up, including a magnetic roller sweep of your property before we leave.
If you’re weighing another repair against a full replacement, we’ll give you an honest assessment. If your roof still has reliable life left, we’ll tell you. If replacement is the smarter call, we’ll explain exactly why.

25+ Years in Business
We started in Mississauga in 2000 and have worked on roofs in every part of the city: Port Credit, Erin Mills, Mineola, Meadowvale, Churchill Meadows, Streetsville, and beyond. Over 3,200 completed projects have shown us what holds in Ontario conditions and what doesn’t. That experience is reflected in every assessment we give and every installation we complete.
Unmatched Quality
We install CertainTeed Landmark and Landmark Pro shingles, GAF Timberline shingle systems, Elevate flat roofing membranes, Gentek siding, and VELUX skylights. These are the products we’d put on our own roofs, chosen because the manufacturer warranties behind them are real, and because we’re certified to install them correctly.
Common Signs Your Roof May Be Nearing the End of Its Service Life
A roof rarely fails without warning. Most start showing subtle signs of wear years before a leak ever shows up inside your home. Catching these early lets you plan on your own schedule instead of scrambling after the next storm. Some of the most common warning signs include:
- Curling, cracked, or brittle shingles
- Missing shingles after a windstorm
- Excessive granules collecting in your eavestroughs
- Repeated leaks despite previous repairs
- Deteriorating flashing around chimneys, skylights, or other roof penetrations
- Soft spots or sagging along the roofline
- Moss or algae holding moisture against the surface
- Visible daylight in the attic
- Rising heating or cooling bills tied to poor attic ventilation
- A roof simply nearing the end of its expected lifespan
Not every one of these means you need a replacement, but each one is worth a professional look before a small concern turns into a much bigger bill.
Six-Step Roofing Process in Mississauga
Replacing a roof involves a lot more than tearing off old shingles and nailing down new ones. A professionally installed roof is a total system, with all parts working together to resist water, wind, snow, ice, and everything else Mississauga’s weather can throw at it, year-round.
We believe homeowners deserve to know exactly what they’re paying for, so here’s the process we’ve refined over more than two decades — built around quality, communication, and long-term performance rather than shortcuts. Every home is a little different, but our approach doesn’t change: exceptional workmanship, premium materials, and the same care we’d want shown to our own homes.
A Thorough Roof Assessment
Every successful roofing project starts long before materials show up. Our first job is to understand the real condition of your existing roof. During the assessment, we look at:
- Shingle condition
- Roof age and remaining life
- Flashing around chimneys and skylights
- Ventilation performance
- Valleys and drainage areas
- Structural concerns
- Previous repairs
- Any spots that could cause trouble down the road
We also take time to answer questions, walk through what we found, and lay out your options clearly. The goal is an informed decision, not a rushed one.
Written Quote & Scope Agreement
Once we’ve completed the assessment, we put everything in writing before any work is agreed or scheduled. Your quote itemizes exactly what’s being installed: the specific shingle or membrane product, underlayment type, ice and water shield coverage, flashing approach, ventilation plan, and cleanup process. You’ll also see the warranty coverage you’re entitled to based on the products and our certifications.
We don’t issue a single price with a vague scope attached. If we find decking that needs replacement, that’s noted separately, so you understand what’s included and why. There are no surprises on the invoice because everything on the invoice was on the quote.
Site Preparation and Tear-Off
Before any work starts, we protect your landscaping, windows, and anything close to the work zone. Tarps go down, eavestroughs get covered, and fragile items are moved or protected. Old shingles and tear-off debris are loaded and removed the same day; we don’t leave materials on your property overnight.
Installation on Your Property
New decking is installed where needed. Ice and water shield goes in at the eaves and valleys. Synthetic underlayment covers the full deck. Shingles are installed to the nail pattern and overlap as the manufacturer specifies because correct installation is what keeps the warranty valid. Flashing at chimneys, skylights, and all roof penetrations is sealed and counter-flashed properly.
Cleanup Post Completion
Once installation is complete, we run a magnetic roller across the full property to collect every nail and metal scrap. Your driveway, garden beds, and lawn should look the same as when we arrived. All tear-off waste is loaded and disposed of off-site.
Inspection & Follow-Up
We walk the completed roof and photograph every section before we leave. If anything doesn’t meet our standard, we fix it on the same visit. Your warranty documentation covering both our workmanship and the applicable manufacturer warranty is provided in writing within 48 hours of project completion.

Roof Inspection
Annual roof inspections help address problems early so they don’t grow in severity and cost. The licensed roofers will check the condition of the shingle or metal panels, the overall roof structure, and elements like the flashing. Our roofing contractors in Mississauga then build a cost-effective plan for any needed repairs. Inspections become more important as your roof ages. Our experienced professionals sometimes suggest replacing the roof early based on the results of our investigation. We only do so if we believe it is the more economical decision.
Roof Installation
A new roof installation needs to be built correctly from the deck up: ice and water shield, synthetic underlayment, shingles laid to manufacturer specifications, and flashing sealed at every penetration. We work with builders and homeowners on new construction projects across Mississauga, installing CertainTeed, GAF, and metal roofing systems. Every new roof is backed by both our workmanship warranty and the applicable manufacturer warranty from day one.
Roof Tune-ups
A roof tune-up catches the small issues – failing caulk around flashings, minor shingle damage, granule buildup in eavestroughs before they become expensive repairs. We inspect, reseal, and document what we find, then give you a written summary with photos. We recommend at least one per year, and after any significant storm. If a repair is needed, we quote it separately before touching anything.
Emergency Roofing
What counts as a roofing emergency? If the condition of your roof puts your health or property in immediate danger, call right away. Storm damage is the most common trigger for emergency roof repairs. It can cause serious leaks, structural damage if a tree comes down, and in rare cases, a fire risk from damaged wiring or chimneys. If you suspect a risk of collapse or fire, get to a safe location first, then call us.
Flat Roof Replacement
Flat and low-slope roofs fail differently than shingle roofs, and they require a different approach to assess and replace. The most common failure points are membrane splits at seams, flashing separations around drains and penetrations, and areas where water has been pooling long enough to work its way through. By the time a flat roof leaks visibly inside, the membrane has usually been compromised for some time.
We install EPDM, TPO, and PVC systems as Elevate (formerly Firestone) certified installers, which means valid manufacturer warranty coverage on every flat roof we replace in Mississauga.
Metal Roof Replacement
If your metal roof shows rust, loose fasteners, or lifting panels, do not wait for a leak to appear inside the home. We assess the panels, fasteners, and flashing first and recommend replacement only when it is the more economical option. Where storm damage is involved, we help you through the insurance claim so out-of-pocket costs stay as low as possible.
Commercial Roofing Company in Mississauga
Above It All Roofing handles commercial flat roof replacement and repair for property managers, building owners, and businesses across Mississauga. We work with EPDM, TPO, and PVC membrane systems and are experienced with multi-unit residential buildings, retail units, and low-slope commercial roofs of all sizes.
We have been installing and replacing commercial roofing in Mississauga since 2000. Every commercial project starts with a written inspection report documenting current membrane condition, drainage performance, penetration sealing, and any prior repairs — so you have a record on file regardless of what you decide to do next.
What Causes the Need for Commercial Roof Replacement?
Even if you’ve properly cared for your roof, certain situations can require installation. The most common causes include:
- Poor initial installation. Seams and flashing are the first to fail when a commercial roof is installed incorrectly. If your building has had repeated leaks in the same areas, the original installation is often the root cause, not the membrane itself.
- Age. Most commercial flat roofs have a service life of 20–30 years depending on membrane type and maintenance history. As the roof approaches that threshold, repair frequency increases and full replacement becomes the more economical option.
- Severe weather damage. Hail, ice damming, heavy snow, and freeze-thaw cycles all stress flat roof membranes. Ontario winters accelerate wear around penetrations and drainage points. After any significant weather event, schedule an inspection before a small breach becomes a large one.
- Deferred maintenance. Commercial roofs need annual inspections to stay in warranty and catch membrane issues early. Small splits, pooling water, and lifting seams are cheap to repair when caught promptly, and expensive when ignored for multiple seasons.
- Impact damage from trees or debris. Falling branches can puncture or displace membrane sections. Impact damage should be assessed immediately after the event; even a small puncture allows water into the roof assembly quickly.
Roofing Challenges We See Across Mississauga Neighbourhoods
After 25 years on Mississauga roofs, we know what tends to go wrong in each part of the city. Find your area below.
Roofing in Port Credit, Lakeview & Clarkson
Wind coming off Lake Ontario pushes rain under shingle edges, ridge caps, and flashing regularly. On streets close to the water, these are almost always the first components to fail. Roofing in this part of Mississauga means accounting for that lake exposure from day one.
Our advice: On exposed lakefront streets, invest in a higher wind-rated shingle. The modest price difference prevents repeated repair calls over the life of the roof.
Roof Replacement in Erin Mills, Meadowvale & Lisgar
Most homes here were built in the 1970s–1990s and are now on their second or third roof. Long roof valleys and poor attic ventilation from the original build are the most common trouble spots we find on roof replacements in this part of Mississauga.
Our advice: Fix the attic ventilation while the roof is off. Installing a new roof over an overheated attic significantly shortens its lifespan, one of the most preventable mistakes in Mississauga roofing.
Mississauga Roofing — Mineola, Lorne Park, Cooksville & Streetsville
Older streets with mature tree canopy, multiple layers of past repairs, and aging flashing around chimneys and skylights. Leaks here rarely have a single cause; by the time water appears inside, it’s usually been travelling through two or three failure points.
Our advice: Have someone physically get on the roof before you accept any roofing quote in this area. A price given from the driveway misses half the story.
Roof Replacement in Churchill Meadows & East Credit
Newer homes, but builder-grade shingles installed when these subdivisions went up are now reaching the end of their service life, often sooner than owners expect.
Our advice: If your neighbours are re-roofing, book a free inspection. Your roof is the same age and almost certainly the same shingles. Getting ahead of it means replacing on your schedule, not scrambling after a storm.
Common Roofing Mistakes Mississauga Homeowners Make
Choosing a Roofing Contractor Based Only on Price
Everyone wants good value, but the lowest estimate isn’t always the lowest long-term cost. A roof replacement involves far more than shingles: materials, workmanship, ventilation, flashing, warranties, safety practices, and cleanup all factor into how the roof performs over time. Compare what’s actually being installed, not just the number on the page.
Waiting Until Water Enters the Home
A visible leak is often one of the very last warning signs, not the first. Most roofs show subtle signs of trouble years before any damage shows up inside. Planning a replacement ahead of a major failure usually means a smaller bill and no emergency scramble.
Ignoring Attic Ventilation
Ventilation affects far more than just attic temperature. It plays into moisture control, energy efficiency, and how long the rest of the roofing system lasts. A complete system always accounts for ventilation, not just what’s visible from the street.
Focusing Only on Shingles
It’s natural to spend most of your time picking shingle colours and styles. Appearance matters, sure, but the hidden components underneath usually have more influence on long-term performance. Underlayment, waterproofing, flashing, ventilation, and proper installation all play a bigger role than most people realize.
Delaying Professional Inspections
Minor concerns rarely get cheaper with time. Small repairs handled early tend to prevent much larger ones down the road, and a professional inspection gives you the information to make that call before it becomes an emergency.
