Roofing Whitby: Contractors You Can Trust
We've been doing roofs in Whitby and across Durham Region for over 20 years—actually replacing roofs the right way, the first time, so they last.
C.D. Roofing & Construction Ltd. handles everything from 1960s bungalows in Brooklyn to new builds in Port Whitby. We're Platinum Certified installers for BP shingles (one of only a handful in the region) and we work with all the major brands—GAF, CertainTeed, Owens Corning, IKO, Malarkey.
Here's what matters: we show up when we say we will, we clean up after ourselves, and we don't disappear once the job's done. Your roof is a serious investment and you deserve a contractor who treats it that way.

Roof Repair in Whitby
Not every problem needs a full replacement. Missing shingles after a windstorm, a leak around the chimney, damaged flashing—these are repairs we handle all the time. The key is catching them early before water gets into your attic and turns a $500 fix into a $15,000 problem.
Whitby gets hit with everything. Lake Ontario keeps things milder than areas further north, but we still see freeze-thaw cycles that wreak havoc on older roofs. Ice dams form along the eaves when your attic insulation isn't doing its job. Wind coming off the lake can lift shingles that weren't installed properly in the first place.
We've repaired roofs that other companies said needed replacing. Sometimes that's true. Sometimes it's not.
Roof Replacement & Re-Roofing
Most asphalt shingle roofs in Ontario last 20-25 years if they're installed correctly and maintained. If your roof is pushing that age, you're probably noticing granule loss in the gutters, curling edges, maybe some discolouration.
A roof replacement isn't just about new shingles. It's about proper ventilation (which most older homes in Whitby don't have), ice and water shield in the valleys and eaves, drip edge, starter strips, and making sure everything is nailed down to withstand the wind loads we see here.
We've done hundreds of re-roofs across Whitby—from the older homes near downtown to the newer subdivisions in Brooklin and Williamsburg. The process is straightforward: we strip everything down to the deck, inspect for any rotten plywood (more common than you'd think), install all the underlayment and protection layers, then install your new shingles. Takes 1-3 days depending on the size of your home and the weather.
Flat Roofing Systems
Flat roofs are everywhere in commercial buildings around Whitby and you'll find them on older homes with additions or modern builds with that contemporary look. They're not actually flat—there's a slight pitch for drainage—but they require completely different materials and installation methods than a sloped roof.
We work with TPO, EPDM rubber, and modified bitumen systems. Each has its place depending on your budget, the building's use, and how long you plan to own the property.
Flat roofs get a bad reputation because they're often installed by the lowest bidder who doesn't understand proper drainage or flashing details. A well-installed flat roof can last 15-25 years. A poorly installed one starts leaking in year three.
Metal Roofing Installation
Metal roofs are becoming more popular in Durham Region and for good reason. They last 40-50 years, they're excellent in high wind areas (which includes most of Whitby), and they shed snow and ice better than asphalt shingles.
The upfront cost is higher—roughly double what you'd pay for architectural shingles—but you'll never need another roof. Insurance companies sometimes offer discounts for metal roofs because they're more fire-resistant and durable.
We install standing seam metal roofing and metal shingle systems. Both look sharp and both will outlast you.
Eavestroughs, Fascia & Siding
Your roof doesn't end at the shingles. Water management is everything and that means functional eavestroughs, properly installed fascia, and siding that isn't rotting behind the trim.
We replace aluminum eavestroughs, repair fascia boards that have deteriorated from years of ice buildup, and handle siding repairs that often come up during a roof replacement. It's all connected and it all matters.

Why Whitby Homeowners Choose C.D. Roofing Company for Roof Repair and Replacement
There are dozens of roofing companies serving Whitby. Some are great. Some are fly-by-night operations that'll be gone by next spring.
We know the area. We've worked on roofs from Oshawa to Ajax, Pickering to Brooklin. We know which neighbourhoods have homes built in the 70s with inadequate attic ventilation. We know where the wind exposure is worst coming off the lake. We know which subdivisions in Whitby used cheaper materials during construction booms and which ones were built to last.
We treat your property like it's ours. That means protecting your gardens with plywood, using tarps during tear-off so nails don't end up in your driveway, and running a magnet over your lawn three times when we're done. It means showing up on time and actually answering the phone when you call.
Our work holds up. We've had customers move out of their homes 15 years after we did their roof and the new owners call us because they found our sticker in the attic. That doesn't happen if you're doing sloppy work.
You can find cheaper quotes. You probably will if you call around. But cheaper usually means shortcuts and shortcuts on a roof mean problems down the road.
We've been doing this in Whitby and across Durham Region for over two decades. We're not going anywhere and we stand behind every roof we install.
Residential & Commercial Roofing in Whitby
We handle both but they're different animals.
Residential roofing is mostly sloped roofs with asphalt shingles, though we're seeing more metal roofs and the occasional cedar shake replacement in some of Whitby's older neighbourhoods. Homeowners care about curb appeal, longevity, and whether their insurance company will cover storm damage claims. The decision-making process is personal because it's your home.
Commercial roofing in Whitby is usually flat or low-slope systems—TPO, EPDM, modified bitumen. Building owners care about lifecycle costs, minimizing business interruption, and meeting Town of Whitby building code requirements. The decision is more about numbers than aesthetics.
We approach them differently because they require different expertise. A roofer who's great at residential shingles might have no business touching a commercial flat roof, and vice versa.
Emergency repairs are a whole other category. A tree branch through your roof during a storm or an HVAC unit that's leaked—these need immediate response, not a two-week wait for a quote. We prioritize emergency calls because we know what water damage can do if it sits.
Recent Roofing Projects in Whitby & Durham Region
We just finished a complete re-roof on a 1980s two-storey in Brooklin. The original builder-grade shingles had lasted about 22 years (which is actually pretty good), but the homeowner wanted something with better wind resistance and a longer warranty. We installed BP Mystique 42 in Weathered Wood—looks great, rated for winds up to 220 km/h, and comes with a lifetime limited warranty.
Last month we handled a tricky flat roof repair on a commercial building in downtown Whitby. The previous roofer had installed TPO but hadn't properly flashed the rooftop HVAC units. Water was getting in around the penetrations every time it rained. We cut out the damaged sections, installed a new insulation board where it had gotten wet, and re-flashed everything properly. Problem solved.
We've done metal roofs in Ajax, emergency repairs in Oshawa, complete tear-offs in Pickering and Port Whitby. Just north in Claremont, we completed a recent cottage roof & skylight replacement in Claremont on a steep A-frame — same fundamentals, tougher pitch. Every project is different but the fundamentals don't change—do it right, clean up after yourself, stand behind your work.
