A Brampton Industry That Processes Food at Scale
Brampton's employment lands are big and they are mostly new. The City's own business park guide puts Airport Intermodal at around 5,400 acres, Highway 410 South at 2,600, the Highway 427 lands at 1,600, Bram West at 1,500 and Bramalea South Gateway at 1,100 — numbers that describe distribution and manufacturing at a scale the inner GTA no longer has room for.
A large share of that is food. Brampton Economic Development describes roughly 300 companies and about 8,500 people working in food and beverage processing and its supporting industries, and the names in that sector are ones you would recognise from a grocery aisle — Maple Lodge Farms, Olymel, Sofina Foods, Lactalis Canada, Italpasta, FGF Brands, Cardinal Meats, Coca-Cola Bottling, with Loblaw's operations among the largest employers in the city. Business Facilities magazine put the city first in North America for food processing several years running.
For a commercial roofing contractor that sector is a specific technical problem, not a marketing fact.
A food plant is not a warehouse with better lighting. It is a building full of refrigerated rooms, washdown bays, cooking and cooling processes, and air that is deliberately held at humidity levels no office would tolerate. All of that pushes upward, into a roof assembly that most people assume is only there to keep rain out.

Your QA lead is going to ask who's above the product. Short answer: our own roofers, nobody borrowed from another outfit. And what owners have said about them is further down the page.
Your Roof Is Being Attacked From the Warm Side
Most roofing conversations are about keeping water out. On a Brampton food plant the more expensive problem is water that is already inside the building, in the air, moving up.
Water vapour moves from warm and humid toward cold and dry. In a Canadian winter that means the moist air in a processing hall or a washdown area drives upward and outward through the roof assembly — and somewhere inside that assembly it reaches a surface cold enough to condense on. Not on your ceiling, where you would see it. Inside the insulation, where you will not.
A cold store reverses the direction and makes it worse. Now the cold side is the inside, and it is the warm, humid summer air outside that is being pulled in toward it. One building-envelope specialist put it about as plainly as it can be put: the cold air inside a freezer wants to wring the water out of any air entering from outside, and in a freezer that condensation doesn't stay water — it becomes ice.
Ice inside a roof assembly is not a slow problem. It is a structural and thermal one.
The thermal part is the bit that surprises owners. Insulation works by holding still air in place; saturate it or freeze it and it stops doing that almost entirely — the effective R-value of frozen boards and board joints is essentially nothing. So the refrigeration plant works harder, the energy bill climbs, and the colder assembly condenses more moisture, which freezes, which drops the R-value further. Nobody notices a leak. They notice the compressors running longer, and they blame the compressors — which is why it is worth understanding how much moisture a roof assembly has to hold back in the first place.
There is a second thing worth understanding, because it changes what you spend money on. Vapour does move by diffusion through materials, but it moves vastly faster through holes. The published comparison is stark — the moisture that passes through a single one-inch gap in a month dwarfs what diffuses through an entire sheet of intact vapour retarder over the same period. Which means air sealing at the details matters more than the perm rating on a data sheet, and a beautifully specified vapour retarder with unsealed penetrations is mostly decoration.
The guidance for when you need one is well established. The roofing industry's own test is that a vapour retarder should be considered where the coldest month averages below about 4°C and winter interior humidity runs at 45% or higher — and separately, wherever interior humidity is simply high, which is the definition of a food plant. Brampton's winters clear that first bar comfortably.
So the question on these buildings is never just which membrane goes on top. It is what the whole assembly is doing about the air underneath it.
What the Cores Tell Us on a Food Plant
We do not diagnose these roofs from the surface, because on a vapour-driven failure the surface is usually the last thing to show it.
The survey runs as a thermal scan of the deck in the late evening, which reads the wet and dry regions against each other, followed by cores cut where the scan says the boundary is. On a refrigerated building we also want to see the underside — the ceiling of the cold room, the vapour seal at the wall-to-roof junction, and the condition around every penetration through it.
What comes back has a pattern. The saturation is rarely at the drains, which is where a conventional inspection concentrates. It clusters over the processing areas and the chilled rooms, and it fans out from the penetrations — hanger rods, refrigeration lines, conduit, sprinkler risers, anything that passes through the assembly and was sealed by a trade other than a roofer.
Frozen cores are their own signal. If a plug comes out with ice in the joints between boards rather than just dampness, the vapour control has been compromised for a long time and the insulation has been doing very little for at least as long.
None of this means the whole roof is finished. Quite often the field is sound and the problem is a defined zone plus a dozen badly sealed penetrations. But it does mean a replacement quoted off building age and a walkaround would be a guess, and on a plant this size a guess is an expensive way to be wrong.
The Crown Warm-Side Survey
On a food plant we work from the inside of the problem outward. Four steps, and none of them is guessing from the surface.
1. Scan the deck in the evening
A thermal scan once the day's heat has gone shows which parts of the assembly are holding water and which read dry.
2. Core the boundary, then check underneath
Cores cut where the scan draws the line between wet and dry, plus a look at the cold-room ceiling, the wall-to-roof seal and every penetration.
3. Put what's wet and what's frozen in writing
A written report after the visit, scan images included, showing where the saturation sits and which penetrations it's spreading from.
4. Two prices and a recommendation
Repair and replacement priced side by side, the system we'd use (usually PVC on food work, SBS where traffic is heavy) and which option we'd spend our own money on.
What Belongs Over a Cooler, and Why It's Not Just a Membrane
Where the assembly has to be rebuilt, the sequence matters more than the brand on the top sheet.
The vapour control goes on the warm side of the insulation — which on a normal heated building means below it, and on a cold store means the opposite, because the warm side is now outside. That single inversion is what most generic roofing specs get wrong on a freezer, and it is not a detail you can correct later without opening the roof again. Whatever we put in has to be continuous with the vapour control coming up the walls, so the building is sealed as one envelope rather than as a roof and some walls that happen to meet.
Then the air sealing, which is where the real performance is won. Every hanger rod, refrigeration line, conduit and sprinkler penetration gets detailed properly rather than caulked, because as above, holes move far more moisture than materials do.
On top, the PVC systems we install are usually the right answer for food and beverage work — dimensionally stable, welded into a continuous sheet, and genuinely resistant to the greases and oils that come out of cooking and rendering exhaust, which most single-plies are not. Our PVC carries material warranties up to twenty years. Where the deck is concrete and the roof takes constant service traffic, SBS modified bitumen is often better, and we install that as well. Hot-asphalt built-up roofing still has a place on the older plants.
Two rules do not move. We do not install TPO or EPDM — we will service them on a building that already has them, but neither belongs on a roof carrying grease-laden exhaust. And every replacement is a complete tear-off to the deck, which on a vapour-damaged roof is not a preference: recovering over saturated or frozen insulation seals the failure permanently inside the building you are trying to fix.
If you want the background on how these assemblies are put together in this climate before we meet, how a flat roof assembly is built here is written up on the site.
When Roof Repair Is Enough and When It Has to Be Roof Replacement
Most owners ask for a price on a new roof when what they actually need is both numbers side by side.
Roof repair is the right answer more often than the trade lets on. If the scan shows a defined wet zone and the rest of the field reads dry, cutting out the saturated boards, rebuilding the vapour control locally and re-detailing every penetration above it will buy years — and on a plant running coolers it buys back refrigeration load at the same time. We quote that as repair services with a scope you can read line by line, not as a holding action with an asterisk on it.
Roof replacement earns its keep when the wet area has spread past roughly a quarter of the field, when the plugs come out frozen rather than merely damp, or when the assembly was built with no vapour control at all and nothing you do above it changes what is happening underneath. At that point a partial fix is money spent twice.
The honest test is whether the cause is local or built into the original design. A dozen badly sealed penetrations is local. A missing vapour retarder over a washdown hall is not.
We put both figures in front of you with the scan attached, and we say which one we would spend our own money on. Twice-yearly inspections afterwards are the cheapest part of the whole exercise — half a day in spring, half a day once the leaves are down, and you catch the shrinking pitch pocket while it is still a tube of sealant rather than a wet bay.
That is also how you maintain what you paid for. Flat roofing systems do not fail on a schedule. They fail where somebody opened them up and closed them badly. An assembly with a maintenance file and a photograph of every curb on it is something you can budget for; one without is something you find out about.
Flat Roofing Is All We Do, and What That Rules Out
It is worth being blunt about the range of work we take, because it is narrower than most roofing contractors in the region and the narrowness is the point.
We do commercial flat roofing and industrial low-slope work. That is the entire list. We do not do homes. We do not do shingles, siding, eavestrough, skylights or metal roofing, and we do not bid all types of work and then go looking for somebody to cover the parts we don't do — there are no subcontracted crews on a Crown job, which is why the outfit that quotes your building is the outfit standing on it.
What we deal with instead is the assembly over a plant, a warehouse or a distribution building: the vapour control, the insulation, the membrane, and every single thing that passes through all three.
The trade-off cuts both ways and we would rather you knew it up front. If you need a storefront re-shingled, call somebody else and we will tell you who to call. If you have a chilled building with ice in the board joints, you want the firm whose roofing services have been pointed at that exact problem since 1977 rather than a generalist who meets it twice a year.
It also means the crew is our crew. Our Brampton roofing crews are on our payroll, trained on our details and carrying our coverage — not a rotating cast from whichever company had availability that week. There are a great many brokers in the Ontario market who will sell you a roof and then hire it out. We are not one of them, and you can check that by asking whose name is on the truck.
Before you call: what plant managers ask us first
Will this mean stopping a line?
It shouldn't. The open section stays small and contained, and anything with flame, fumes or odour gets timed around your air intakes and your runs. Your QA or food safety lead sees the sequence before we mobilise.
What if the problem's actually the refrigeration?
Then you've found that out without buying a roof. Our seasonal inspection costs nothing, and any quote that follows is itemised line by line, so you can see what's roof and what isn't.
Our Brampton Flat Roof Work, and Fifty Years of Only Doing This
Crown started in 1977 and has never taken on anything but commercial and industrial flat roofs. Fifty years, one trade, our own crews — we do not subcontract the work and you will not meet a different company on your roof than the one you hired. Brian Sharp founded it. Joe Ferrier is President.
Our Brampton job on the board closed in June 2024 and the Brampton work is posted in the gallery with the photographs the crew took on the roof. We list jobs by city and month and leave them at that.
What we would rather do, for a plant, is come and look at yours. A food or refrigerated building is not something to quote from a satellite image and a building age, and the useful first meeting is one where somebody who has opened a lot of these assemblies is standing on yours with a moisture meter.
Ask for that. It costs you an hour.
What Building Owners and Businesses Have Written
Our business in Aurora had several leaks in the roof to our shop. Crown Roofing was amazing to deal with. Their worker Arvin was such a great guy and was really thorough in explaining where all the leaks were. He took photos to show us where the leaks were coming from. They also found a forth leak and fixed it in good faith without billing us.

I waited for all seasons before giving this review as I wanted to give a transparent and accurate review. I received multiple quotes and decided to use them to replace the roof on our building.

Permits, Food Safety, Frozen Insulation and Dry Warehouses
Do I need a building permit to re-roof a commercial building in Brampton?
Assume you might, and let us confirm it rather than guessing. The City publishes a permit exemption for replacing asphalt shingles without structural alteration, but that sits in the homeowner section and is written for residential roofs — there is no published exemption covering industrial or commercial low-slope work. On a food plant the scope usually includes added insulation, new or raised curbs and sometimes deck repair, any of which can put the job squarely into permit territory. We check your actual scope against the Building Division before we quote, and where a permit is required we prepare and file the application through the City's building portal.
Can you work above a live food production area?
Yes, and it is a different job from working over a warehouse. Foreign material control governs everything: the tear-off face stays small and fully contained, debris is managed so nothing can reach product or packaging below, and anything involving open flame, fumes or odour is scheduled against your air intakes and your production runs rather than our convenience. We walk the sequence with your QA or food safety lead before we mobilise and work to your site's requirements for access, hygiene and sign-in. Condensation control is a live food safety concern in its own right, so on most plants the QA team is already interested in the roof — bring them into the first meeting.
Our freezer roof has ice in the insulation. Does that mean the whole roof is gone?
Not necessarily, but it does mean the vapour control has failed somewhere and the insulation in that zone has stopped working. The first job is to find out how far it has spread and where the air is getting in, which is a scan plus cores plus an inspection of the underside seal — and often the answer is a defined region over the coldest rooms plus a set of penetrations that were never properly detailed. If the field outside that zone is dry and sound, a targeted replacement with the vapour control and air sealing corrected can be the right answer. What does not work is leaving it: frozen insulation carries on costing you refrigeration every day, and the wet area spreads.
We run a dry warehouse, not a food plant. Does any of this apply?
Less of it, and that's worth knowing before someone sells you an assembly you don't need. A dry distribution building at normal interior humidity does not face the same vapour load, and the specification can be simpler and less expensive. The things that still matter on those roofs are drainage, the quality of the detailing around rooftop units, and traffic protection. If a contractor is quoting you a heavy vapour control package for a dry warehouse, ask what interior humidity they are designing for. For most Brampton distribution buildings the honest answer is a well-detailed roof, an inspection each spring and fall, and no drama.
Find Out What Your Roof Is Costing You in Refrigeration
If your plant runs coolers or freezers and the roof has never been scanned, there is a reasonable chance you are paying for it every month in energy without a single drop of water ever appearing on a floor.
Call (416) 744-7788 or email info@crownroofing.ca. We will scan the assembly, pull cores, look at the underside seal, and give you a written picture of what is wet, what is frozen, and what it would take to fix the cause rather than the symptom.
The same assessment works for businesses that run dry warehousing and distribution rather than food — the vapour load is lower, the penetration count usually is not, and a commercial roof carrying that much rooftop equipment has the same failure pattern for different reasons. Our roofing crews cover the 410 and 427 employment lands, Bram West and Bramalea, and the team can usually be on a roof inside a week.
