Roof Replacement in London, Ontario: What to Expect

Much of London's housing went up between the 1950s and 1980s, and many of those roofs are on their third set of shingles. After twenty winters of freeze-thaw, curling tabs and bare granule patches are common across Westmount, Oakridge and the north end.

A replacement here means a full tear-off, a sheet-by-sheet deck check, ice and water shield at the eaves and valleys, synthetic underlayment, and architectural shingles rated for Southwestern Ontario wind.

Every job starts with an inspection and a written scope, so you know what is included and what it costs before you commit.

How It Works

Your Roof, Done in 4 Steps

From the first call to the final walkthrough, here is what happens and when.

Roof Inspection and Scope

A roofer walks the roof and attic, photographs problem areas, and writes up exactly what the job includes and what it costs.

Tear-Off and Deck Check

Old shingles and underlayment come off into the bin. The plywood deck is checked sheet by sheet and any soft or rotten spots are replaced.

Underlayment, Shield and Shingles

Ice and water shield goes on at the eaves and valleys, synthetic underlayment over the rest, then drip edge, starter strip, shingles, flashing and ridge cap.

Cleanup and Walkthrough

Magnetic sweep of the lawn and driveway, eavestroughs cleared, bin picked up, then a walkthrough of the finished roof with you and the photos to match.

Where It Works

Ideal Applications for Roof Replacement

Aging Shingle Roofs

Roofs past 18 to 25 years with curling, cracking or heavy granule loss across most slopes.

Storm-Damaged Roofs

Wind or hail damage spread widely enough that patching would cost more than starting over.

Pre-Sale Replacements

Homeowners replacing a tired roof before listing so an inspection does not stall the sale.

Layered Roofs

Homes with two layers of shingles already on, where a third is not an option.

Post-Purchase Upgrades

New owners tackling a roof the home inspection flagged as near end of life.

Common Questions

Roof Replacement — Frequently Asked Questions

How much does a roof replacement cost in London, Ontario?
Most London roof replacements in 2026 land between $8,000 and $14,000 for a bungalow and $14,000 to $22,000 for a two-storey home, based on published market ranges. Roof size, pitch, the number of valleys and vents, and any deck repair move the number. A written quote after an inspection is the only way to pin it down for your house.
How long does a roof replacement take?
One to two working days for most homes. Tear-off and deck inspection happen the first morning, and the new roof is usually dried in the same day. Larger or steeper roofs, or ones that need deck repair, can run into a third day.
What happens if you find rotten decking under the old shingles?
It gets replaced before the new roof goes on, and you are told before the work happens. The quote spells out the per-sheet price for deck replacement ahead of time so there is no surprise on the invoice.
Does the quote include tear-off and disposal?
Yes. Tear-off, bin rental, disposal and cleanup are line items in every replacement quote. Some quotes in the market leave these out and add them later, which is worth checking when comparing.
What is ice and water shield and do I need it in London?
It is a self-adhering membrane installed along the eaves and in valleys under the shingles. In London's freeze-thaw winters it is what stops meltwater backed up behind an ice dam from getting into the house, so it is part of every replacement quoted here.
