When a roof is past repair, replacement is the right call. Guns N' Hoses handles the full process — removal of existing materials, installation of new roofing system, and complete site cleanup. Every replacement comes with a written quote before work starts and a workmanship guarantee after.

What a Roof Replacement
Costs in Ottawa

Cost depends on roof size, pitch, number of existing shingle layers, and material choice. Ottawa Building Code allows a maximum of two shingle layers — if your roof already has two, full removal is required before replacement can begin.

Home Size Typical Cost Timeframe
Under 1,200 sq ft $8,000 – $11,000 1 day
1,200 – 2,000 sq ft $11,000 – $16,000 1–2 days
2,000 – 3,000 sq ft $16,000 – $22,000 2 days
Large or complex roofs $22,000+ 2+ days

How a Roof Replacement
Works

01

Inspection & Written Quote

We assess your existing roof, take precise measurements, and deliver a detailed written quote. The price we quote is the price you pay — no surprises on invoice day.

02

Material Selection

We walk you through material options suited to your home and Ottawa's climate. Asphalt shingles, flat membrane systems, or metal roofing — we recommend what's right, not what's most expensive.

03

Full Removal & Installation

Old materials are removed responsibly. New roofing system installed to Ontario Building Code standards — ice shield minimum 900mm up the slope and 300mm past the interior wall line. On most Ottawa jobs we go further than code minimum.

04

Cleanup & Warranty

The site is left clean. Every replacement comes with a full manufacturer warranty plus our workmanship guarantee. We follow up at 30 days to confirm everything is right.

Built for Ottawa
Winters

Ottawa's freeze-thaw cycle is one of the most demanding roofing environments in Canada. Snow accumulates, partially melts, and refreezes repeatedly all winter. A properly installed replacement roof accounts for this from day one — correct ice shield coverage, balanced ventilation, and materials rated for the temperature range Ottawa actually experiences. Cutting corners on any of these means callbacks in year two or three.

Common Questions About
Roof Replacement in Ottawa

How long does a roof replacement take in Ottawa?
Most Ottawa homes take one to two days. A house under 1,200 sq ft is typically done in a single day. Larger or more complex roofs may take two days. We confirm the timeline in your written quote before work begins.
Do I need a permit to replace my roof in Ottawa?
Most like-for-like residential roof replacements in Ottawa do not require a permit. If structural changes are involved, or if the roof is part of a larger renovation, a permit may be required. We confirm this during the quote process.
Can you replace my roof in winter?
Yes. We replace roofs year-round in Ottawa. Cold-weather installation requires specific techniques and materials — we follow manufacturer guidelines for low-temperature application on every winter job.
What's the difference between repair and replacement?
If more than 30% of your roof is damaged, or if the roof deck itself is compromised, replacement is almost always the better investment. We give you an honest assessment during the inspection and will tell you clearly which one your roof actually needs.
How many shingle layers can a roof have in Ottawa?
Ontario Building Code allows a maximum of two shingle layers. If your roof already has two layers, full removal is required before a new system can be installed. We check this during inspection and include it in the quote.

What Ottawa Homeowners
Say

“Vanessa and her team did my parents' roof a few months back. She was very quick to respond and communication was great. She had a lot of patience explaining things to my parents as they don't speak English very well.”

— Jenn, South Keys, Ottawa

“I would highly recommend. We had a leak in our roof and Vanessa and her team were able to fix the issue in a timely manner. We will be using her services again.”
