About Roof Replacement

Most asphalt shingle roofs in Ontario last between 20 and 30 years, depending on installation quality, ventilation, and maintenance. When repairs become frequent, costs start adding up, or your roof is simply at the end of its lifespan, a full replacement is the smarter long-term investment. A new roof improves your home's curb appeal, energy efficiency, and resale value — often paying for itself when you sell.

LocalRoofer.ca works with licensed GTA roofing contractors who specialize in full tear-offs and replacements. We use premium materials rated for Ontario's harsh winters — including impact-resistant shingles, proper underlayment, ice and water shield along eaves and valleys, and ridge ventilation systems that prevent ice dams and extend the life of your new roof.

Our contractors will walk you through material options, colour choices, and warranty terms before any work begins. From a standard three-tab shingle replacement to architectural shingles, metal roofing, or a flat roof system, we'll match you with the right contractor for your home and budget.

Our Roof Replacement Process

Here's exactly what happens from your first call to completed work — no surprises.

Consultation & Detailed Quote

A contractor visits to measure your roof, assess decking condition, and discuss material options — architectural shingles, metal, or flat systems. You receive a detailed written quote covering materials, labour, disposal, and warranty terms.

Tear-Off & Deck Inspection

The crew removes all existing shingles, underlayment, and flashing down to the roof deck. Each sheet of plywood or OSB is inspected; any rotted or damaged decking is replaced before new materials are installed.

Installation of New Roofing System

Ice-and-water shield is installed along all eaves, valleys, and penetrations per Ontario Building Code requirements. Synthetic underlayment is laid over the full deck, followed by your chosen shingles, new step and counter flashing, and a ridge vent system.

Final Walkthrough, Clean-Up & Warranty

A site inspection confirms every fastener, seam, and flashing detail meets standard. All old materials are loaded and hauled away, the property is magnetically swept for nails, and you receive written copies of both the manufacturer's material warranty and the contractor's workmanship warranty.

Signs You May Need Roof Replacement

Watch for these warning signs — catching problems early saves money and prevents larger damage.

Your roof is 20 years or older and has never been replaced — most Ontario asphalt shingle systems reach end of life between 20 and 30 years

You've had multiple repairs in the past few years and leaks keep reappearing in new locations

Widespread shingle granule loss leaving bare, dark patches visible from the ground

Shingles are curling, buckling, or showing widespread cracking across large sections of the roof

Sagging areas on the roof deck suggest decking rot or structural failure beneath the shingles

Common Questions About Roof Replacement

Answers to the questions homeowners ask us most about this service.

How much does a full roof replacement cost in the GTA?

For a typical 1,500–2,000 sq ft bungalow or two-storey home in the GTA, a complete asphalt shingle replacement including tear-off usually ranges from $8,000 to $16,000, depending on roof complexity, pitch, and material grade. Premium architectural shingles and added features like ice-and-water shield upgrades or new decking will push costs higher. You'll receive a firm written quote before any commitment.

Do I need a permit to replace my roof in Ontario?

In most Ontario municipalities, a like-for-like shingle replacement on a residential home does not require a building permit. However, if structural work is involved — such as replacing roof decking, changing the roof system type, or modifying the roof structure — a permit may be required. Your contractor will advise you and can pull any required permits on your behalf.

How long does a roof replacement take?

Most residential roof replacements are completed in one to two days. A straightforward bungalow in good weather is typically done in a single day. Larger homes, steep pitches, or jobs requiring significant deck repair may take two to three days. Weather can occasionally cause delays, but your contractor will keep you informed.

What's the difference between 3-tab and architectural shingles?

Three-tab shingles are a flat, uniform product with a 25-year warranty — functional and cost-effective. Architectural (laminated) shingles have a multi-layered texture that mimics wood shake, carry 30–50 year warranties, and are more resistant to wind and impact. Most GTA homeowners choose architectural shingles for the combination of longevity, appearance, and resale value.

Can a new roof go over the old one?

While some jurisdictions permit a second layer of shingles over an existing one, we recommend against it and most quality contractors won't do it. Layering traps moisture, adds structural weight, prevents deck inspection, and voids manufacturer warranties. A full tear-off gives you a clean inspection of the deck and a roof system that performs as designed.
