Roofing contracts in Canada vary widely in quality and warranty terms. Some roofers offer comprehensive warranties (10-25 years); others offer minimal coverage. A roofing contract should specify the materials being used (shingle type, brand, grade), the workmanship warranty period, and what is covered (leaks, material defects, installation errors). However, many contracts include vague language about warranty exclusions, allowing roofers to deny claims for weather damage, poor ventilation, or other factors they claim aren't their responsibility. Additionally, payment terms for roofing projects can be problematic. Some roofers require full payment upfront before completing work; others overcharge for change orders. Before signing a roofing contract, you need clarity on materials, warranty, payment schedule, and what work is included.
What is a Roofing warranty and workmanship guarantees?
A roofing contract outlines the scope of work (roof replacement, repair, inspection), materials (shingle type, underlayment, flashings), cost, timeline, payment schedule, and warranties. Warranties typically cover manufacturing defects (material warranty) and installation workmanship (workmanship warranty) for specified periods. The contract should clearly define what is and isn't covered.
Red flags to watch for
Roofing contracts should include both material warranties (from the manufacturer) and workmanship warranties (from the roofer). If only manufacturer warranty is mentioned, the roofer is avoiding responsibility for poor installation.
Industry standards in Canada typically include 5-10 year workmanship warranties. A 1-2 year warranty is below standard and signals the roofer may not stand behind their work.
Warranties that exclude 'weather damage', 'wind damage', 'ice damming', or 'poor ventilation' are often unreasonable. Installation errors and ventilation design should be the roofer's responsibility.
Industry practice is typically a small deposit (10-20%) with final payment at completion. If the roofer demands 50% upfront, there's risk you'll lose money if work is incomplete or poor quality.
Roofing projects often uncover issues requiring additional work. The contract should define how change orders are approved and priced to avoid surprise billing.
If the contract states 'premium shingles' but allows the roofer to substitute lower-grade materials without permission, you could end up with inferior materials.
The contract should specify start and completion dates. If completion is open-ended, projects can drag on indefinitely.
Your legal rights
In Canada, provincial consumer protection laws apply to roofing contracts. Ontario's Consumer Protection Act, BC's Business Practices and Consumer Protection Act, and similar legislation require clear contracts with defined scope, pricing, and timelines. Roofing work is subject to implied warranties of quality and workmanship even if the contract is silent. If a roof fails prematurely due to poor installation, the roofer can be sued for breach of warranty or negligence. Building codes (National Building Code of Canada) set minimum standards for roofing installation.
Questions to ask before you sign
- 1What roofing materials will you use (shingle brand, grade, lifespan)?
- 2Can you substitute materials if the specified ones become unavailable, and if so, at what cost?
- 3What is your workmanship warranty period, and what does it cover?
- 4Are leaks due to poor installation or design flaws covered under warranty?
- 5What is your payment schedule (deposit, progress payments, final payment)?
- 6What happens if we discover additional roof damage during the project?
- 7If the roof fails or leaks within the warranty period, how do you handle warranty claims?
