Roofing Replacement and Repair Burlington Has Trusted Since 1978

Repair or Replace Is a Question We Answer With Numbers

Most homeowners ask it the day they see a stain on the ceiling, and many roofing companies answer it with whichever job pays more. We answer it with five measurements taken on the roof, and the quote shows them.

A focused repair on a 10-year-old roof with one failed pipe boot is money well spent. A third patch on a 22-year-old roof with granules filling the eavestroughs is not, and we say so. Minor repairs that make sense get quoted as minor repairs. Either way the decision is yours, made with the photographs in front of you.

Wind Off the Lake Lifts Shingles Before It Tears Them

Burlington’s wind damage rarely starts with a shingle flying off. It starts with the sealant strip losing its bond, so the tab lifts in a gust, lets rain under the course, and settles back down looking fine. Streets near LaSalle Park and the waterfront take the lake wind head on; the north end takes the downslope gusts off Mount Nemo. The May 2022 derecho that crossed southern Ontario, with gusts of 121 km/h recorded at Pearson, is the kind of storm that finds every tab that has already lost its bond. Our Burlington roofing crews install asphalt shingles to the high-wind specification the manufacturers publish: six nails per shingle instead of four, a starter course bonded at the eaves and rakes, and hand-sealed tabs on exposed edges. We check the sealant bond on every repair call, because a roof that has started lifting will keep lifting until it is resealed or replaced.

Roof Repairs That Chase the Leak to Its Source

Water in a Burlington house often travels a long way before it shows. A stain over the stairs can come from a chimney saddle, a cracked skylight curb, a valley where two slopes dump onto one valley metal, or a step flashing that was never counter-flashed. Our roof repairs begin with the inspection, not the patch, because repairs that skip it come back. The inspection covers the attic for frost and damp sheathing, the field for missing shingles and exposed nails, and the details where most leaks on a sloped roof start. The repair itself is done with the same roofing materials and the same crew we use on a new roof, and we leave a photo record of the before and the after. After a wind storm, that record goes to your insurer with the estimate; insurance claims move faster when the roofing contractor has already documented the damage.

A New Roof From Tear-Off to Magnet Sweep

Tear-off and deck check. Old shingles come off to bare deck, and every soft or delaminated sheet is replaced before anything new goes on.

Ice and water membrane. The Ontario Building Code requires eave protection on shingle roofs; on lakeside streets we run it higher up the slope and up every valley.

Underlayment and shingles. Synthetic underlayment over the deck, then the architectural shingles you chose, installed to the manufacturer’s high-wind pattern.

Flashings and ventilation. New drip edge, new flashing at every wall, chimney and skylight, and ridge and intake vents balanced so the attic breathes.

Cleanup and warranty. Our bin leaves with the debris, the lawn gets the magnet sweep, and you receive the 25-year workmanship warranty and the manufacturer’s paperwork.

A typical Burlington roof is torn off and reshingled in one to two days, with the crew weather-proofing anything left open before they leave each evening.

Quality Roofing Products Picked for the Street, Not the Catalogue

The right roof on a Roseland lakefront lot is not the right roof on a Headon Forest cul-de-sac under mature maples. We are certified installers for GAF, Owens Corning and CertainTeed, carry GAF Master Elite status, and we match the quality of the roofing systems to the exposure: wind-rated architectural shingles and full-eave ice and water shield near the water, algae-resistant shingles and extra attention to debris where trees overhang, and a hard look at builder-grade shingles in Millcroft and Orchard, where many first roofs from the 1990s and 2000s are reaching the end of their life at the same time. Flat sections on additions and garages get TPO or modified bitumen installed to the manufacturer’s detail, and metal roofing is on the table where the structure and the budget suit it. Siding, soffit and eavestroughs can be quoted on the same visit so the exterior is finished once.

Heritage Streets and the Permit Desk in Burlington, Ontario

Burlington’s building permit rules are simple for most roofs: replacing shingles with the same material does not need a permit as long as the roof has fewer than three layers, which is why we check the layer count on the first visit. Structural changes, a new skylight opening or a different roofing material can need one, and we tell you before the quote is signed. Heritage is the exception. Properties inside the Burlington Avenue and Ontario Street Heritage Conservation District, whose plan and guidelines City Council approved on 2 March 2026, and individually designated houses under the Ontario Heritage Act need an approved heritage permit for exterior changes that affect protected attributes, and the City can take up to 90 days to process one. Listed but non-designated properties carry no restriction on alterations. We confirm the status with the City’s heritage staff before scheduling, so a roof on Ontario Street is not stopped by a permit nobody mentioned.

A Family-Owned Burlington Roofing Company Since 1978

• 1978. John D’Angelo starts the company in Hamilton with a rule that still holds: no subcontractors.
• Second generation. Sons Aaron and Andy grow it into a team of more than 250 people and 500 installers, all on the payroll.
• Certifications. GAF Master Elite and President’s Club, plus certified installer status with Owens Corning, CertainTeed, James Hardie and Alu-Rex.
• Today. 50,000+ projects, a 4.8-star average from more than 3,000 reviews, a BBB A+ rating and the same 25-year workmanship warranty on every roof, whether the job is a repair or a replacement.

That history is why customers in Burlington still get a D’Angelo on the phone when something needs sorting out.

What Moves the Price of a Burlington Roof

Ontario’s consumer guidance on hiring a roofer asks for a written contract with the materials, the scope and both warranties spelled out, plus proof of liability insurance and a WSIB clearance. Our estimate is built that way, with 0% financing options through Financeit where you want them. We do not publish a per-square price, because the deck and the layer count are not known until a roofer is on the roof, and the quality of what goes back on changes the price more than the size does.

Checks in Spring and Fall That Keep the Warranty Working

• Clear the eavestroughs and downspouts in late fall and again after the maples drop their keys in spring
• Look along each slope from the ground for lifted tabs, missing shingles and exposed nails after any wind warning
• Check the attic in January for frost on the nails or damp insulation, which means the ventilation is not keeping up
• Have the sealant at skylights, vents and chimneys checked every few years, since caulking fails before shingles do
• Call us for flat roof snow removal when drifts build on a low-slope addition

Small roof repairs identified on these checks are the cheapest roofing work we do, and they keep both the workmanship and manufacturer warranties intact. Customers on a maintenance routine tend to get more years from a roof than the ones who call after the first leak.

People Also Ask

Is it cheaper to repair or replace a roof in Burlington?

A repair is cheaper when the roof is under about 15 years old, the damage sits in one area and the deck is dry. Once a roof is past 20 years, has leaked in several places or needs a second or third patch, replacement costs less over the next decade than repeated repairs.

How much does roof replacement cost in Ontario?

It depends on the size and pitch of the roof, how many layers come off, the condition of the deck, the number of skylights and chimneys and the shingle tier chosen. We give every Burlington homeowner a free, itemized estimate after an inspection rather than a published range.

How long does a roof replacement take?

Most detached-house roofs in Burlington are torn off and reshingled in one to two days. Larger roofs, steep pitches, deck repairs or heritage reviews add time, and the schedule is confirmed in the quote.

Do you provide snow removal for flat roofs in Burlington?

We do. Our crews clear heavy snow from residential and commercial flat roofs and remove ice dams from sloped roofs through the winter, which protects both the structure and the membrane.

Do you offer roofing services in nearby areas like Oakville?

Oakville, Hamilton, Milton and the rest of Halton get the same crews, so a Burlington quote and an Oakville quote come from the same office and the same installers. Repairs and replacements are quoted the same way in every city we serve.
