Why It Matters

The Real Cost of
Waiting

A failing roof doesn't stay contained. The longer it sits, the more it costs — and not just to fix the roof.

01
Small Leaks Become Structural Damage
A minor leak through one BC winter can saturate insulation, rot roof decking, and compromise structural framing. A $3,000 repair becomes a $15,000 rebuild.
02
Mould Remediation Adds Thousands More
Persistent moisture creates mould within 24–48 hours. Professional remediation in BC averages $5,000–$15,000 — on top of whatever roofing costs you were already avoiding.
03
Emergency Repairs Cost 3× More
A planned replacement is efficient and competitively priced. An emergency repair after a storm commands premium rates, rushed timelines, and limited contractor availability.
04
A Failing Roof Kills Your Resale
Buyers and home inspectors flag roof condition immediately. An aging roof either kills deals or forces price reductions averaging $10,000+ — far more than a timely replacement.
05
Energy Costs Rise Year Over Year
Failing insulation and compromised ventilation drive up heating and cooling bills every season. A properly installed roof system pays for itself over time in reduced energy costs.
06
Your Warranty May Already Be Void
Most manufacturer warranties are voided by deferred maintenance. If a previous contractor skipped proper installation steps, you may have no warranty protection at all right now.

Roof Replacement Questions

Straight answers to what homeowners ask us most.

How long does a roof replacement take?

Most single-family roofs are done in two to four days once we start, depending on size, pitch and the weather. Larger or more complex roofs take longer. We give you a timeline with the quote.

Do I need to be home, or move out?

You do not need to move out and you do not need to be home. It is noisy, so plan around it if you work from home or have young children napping. We will need access to the driveway and to power.

What happens if you find rotten decking under the old roof?

It happens on a minority of roofs and you cannot see it until the old roofing is off. We show you the affected area, tell you what it costs to replace before we do it, and you decide. We do not do the work and bill you for it afterwards.

Do you tear off the old roof or go over it?

We tear off. Going over an existing layer hides the condition of the decking, adds weight, and shortens the life of the new roof. It also limits what the manufacturer will warrant.

How much does a new roof cost in Metro Vancouver?

It depends mainly on size, pitch, material and access. We have written a full breakdown of the ranges and what moves them in our 2026 cost guide. For your specific roof, we inspect it and give you a fixed-price quote at no charge.

What warranty do I get?

A manufacturer warranty on the materials, up to 50 years depending on the product, plus a 10-year Stonnex labour warranty on asphalt shingle and metal. Both are explained on our warranty page.
