If you’ve collected multiple roofing quotes, you’ve probably noticed something confusing: prices can vary by thousands of dollars — even for the same house.
That doesn’t always mean one contractor is overpriced. It usually means the scope is different.
Roofing quotes aren’t just prices — they’re plans for how your home will be protected from water, ice, and long-term damage.
Read on to learn what should always be included in your roofing quote, the biggest red flags to watch for, and how to compare estimates confidently so you don’t overpay — or under-protect — your home.
Why Roofing Quotes Differ So Much in Ontario
Ontario roofs deal with heavy snow loads, freeze–thaw cycles, and moisture risks that warmer climates don’t face. Because of that, installation details matter more here — and not every contractor includes the same protections.
One of the biggest hidden risks is moisture inside the attic and roof structure.
The Canada Mortgage and Housing Corporation (CMHC) explains:
Moisture accumulation in building materials can lead to deterioration, mould growth and reduced thermal resistance.
If ventilation or moisture control isn’t addressed in a quote, you may be looking at future problems — even if the shingles themselves are new.
The Biggest Mistake Homeowners Make Comparing Quotes
Many people compare roofing quotes like they’re buying the same product from different stores.
But roofing isn’t a product — it’s a system.
Two contractors can install the same shingles and produce completely different results.
The quality of the result depends on many things including:
Flashing quality
Ventilation adjustments
Ice barrier coverage
Installation methods
Cleanup practices
Workmanship warranty
A cheaper quote often means something has been left out.
What Should Always Be Included in an Ontario Roofing Quote
A clear quote should explain:
Exact Materials - Brand and product line — not just “asphalt shingles.”
Eave Protection (Ice & Water Shield): Where it will be installed and how far it extends.
Underlayment and Accessories: Starter strips, ridge caps, and related components.
Ventilation Work: What exists today and what will change.
Flashing Replacement: Chimneys, walls, skylights, and valleys.
Cleanup and Disposal: Including site protection.
Workmanship Warranty: What happens if there’s a leak and who covers it.
If these aren’t clearly described, you’re not comparing quotes properly.
Red Flags to Watch For
When you get a quote, keep an eye out for:
Extremely short or vague estimates
Missing ventilation discussion
No flashing replacement mentioned
No written warranty explanation
Large price differences without justification
These don’t automatically mean poor work — but they deserve questions.

Frequently asked questions
Why is one quote so much cheaper?
Often because certain protections or scope items are excluded.
Do contractors always replace flashing?
No. Some reuse existing flashing unless replacement is specified.
Is ventilation really that important?
Yes — it affects moisture, lifespan, and warranty conditions.
What warranty should I expect?
Both manufacturer material coverage and contractor workmanship coverage.
