Roofing Questions from London Homeowners
Straight answers on cost, timing, materials and where we work.
Pricing & Quotes
How much does a new roof cost in London, Ontario?
Published 2026 ranges for London put a shingle roof replacement at about $8,000 to $14,000 for a bungalow and $14,000 to $22,000 for a two-storey home. Metal runs two to three times that. Roof size, pitch, valleys, vents and deck condition all move the number, which is why the price is written down after an inspection rather than guessed over the phone.
How do I know if my roof needs to be replaced or just repaired?
Local damage on a roof with years left, such as a few lifted shingles or a failed flashing, is a repair. Curling, cracking or granule loss across most slopes, or a roof past 20 years with repeated leaks, usually points to replacement. The inspection report shows photos and says which, and why.
How long does a roof last in Ontario?
Architectural asphalt shingles typically last 20 to 30 years in Southwestern Ontario when the attic is ventilated properly; 3-tab shingles less. Metal roofs are rated for 40 to 70 years. Freeze-thaw winters and hot attics are what shorten a roof's life here.
What should a roofing quote in London include?
Tear-off and disposal, deck repair pricing per sheet, ice and water shield, underlayment, the shingle line and colour, flashing, ventilation, and cleanup. If any of those are missing from a quote you are comparing, ask before you sign, because they tend to appear later as extras.
Repair or Replace
What time of year is best to replace a roof in London?
Late spring through fall is ideal, because shingles need warmth to seal. Spring is the busiest season and published figures suggest prices run a little higher then. Booking an inspection in late summer or fall often means a quieter schedule.
Is $30,000 too much for a roof?
For a standard shingle roof on a typical London home, yes, that is above the published range. For a large or complex roof, a metal system, or a job with extensive deck replacement, $30,000 can be reasonable. The itemized scope is what tells you whether the number is justified.
Will insurance cover a 20-year-old roof in Ontario?
Sometimes, for sudden storm damage, though many policies pay a depreciated value on older roofs. Insurance does not cover a roof that has simply worn out. Photos from the inspection can support a claim either way, and the adjuster makes the final call.
My roof is 20 years old but not leaking. Should I replace it?
Not necessarily. An inspection tells you how much life is left; some 20-year-old roofs have five good years, some are one storm from failing. Replacing on your own schedule, in a mild season, is usually cheaper and less stressful than replacing after a leak.
Materials & Weather
Do you work outside London, in places like St. Thomas or Strathroy?
Yes. The crew covers about a 40 km radius from London, including St. Thomas, Strathroy, Woodstock, Ingersoll, Dorchester, Komoka, Ilderton and Lucan.
What are the signs I need a new roof?
Shingles curling at the edges, bare patches where granules have washed off, cracked or missing tabs across several slopes, daylight or staining in the attic, and granules collecting in the eavestroughs. One of these is a repair conversation; most of them together is a replacement.
How do I prevent ice dams on my roof in London?
Ice dams form when attic heat melts snow that refreezes at the cold eave. The fixes are better attic insulation, proper soffit and ridge ventilation, and ice and water shield under the shingles at the eaves so any meltwater that backs up cannot get inside.
Are metal roofs worth it in Southwestern Ontario?
For homeowners staying long term, often yes. Metal costs two to three times an asphalt roof up front, sheds snow instead of building ice dams, and is rated for 40 years or more, so it can outlast two shingle roofs. For a shorter stay, a good architectural shingle roof is the better spend.
Service Areas
How long does a roof replacement take in London?
One to two working days for most homes. Tear-off and deck inspection happen the first morning and the roof is typically dried in the same day. Weather, steep pitches and deck repairs can add a day.
Do you do roofing in Woodstock and Ingersoll?
Yes. Woodstock and Ingersoll sit at the eastern edge of the service area along the 401 and are covered for replacements, repairs, metal and flat roofs.
Which London neighbourhoods do you cover?
All of them, from Byron and Westmount in the west to Old East Village and Argyle in the east, Old South and White Oaks in the south, and Masonville, Stoneybrook and Hyde Park in the north.
Not Sure If It's a Repair or a Replacement?
Book an inspection. A roofer walks the roof and attic, shows you the photos, and puts the scope and price in writing. No obligation either way.
