Getting quotes is the smart first step in any roofing project, but the quotes themselves can be confusing. One company hands you a single number, another gives you three pages of line items, and the totals are hundreds or thousands of dollars apart. Without knowing what each part means, it is hard to tell whether you are comparing the same work, or whether the cheapest bid is leaving something out.
Here is a plain-language guide to reading a roofing estimate so you can compare quotes fairly and choose with confidence.
Why Estimates Vary So Much
Two honest quotes for the same roof can still differ for good reasons: different shingle lines, different amounts of plywood replacement assumed, whether old layers are torn off or roofed over, and the level of detail in flashing and ventilation work. A low number is not automatically a better deal, and a high one is not automatically padded. The goal is to understand what is included so the comparison is apples to apples.
The Main Parts of a Roofing Estimate
Most thorough estimates break down into the same core sections. Here is what each one covers and why it matters:
| Line item | What it covers | Why it matters |
|---|---|---|
| Tear-off and disposal | Removing old roofing and hauling it away | A roof-over skips this but can hide problems and shorten roof life |
| Decking and repairs | Inspecting and replacing damaged plywood | Rotten decking found mid-job is a common source of surprise costs |
| Underlayment and membrane | The water barrier under the shingles | Ice-and-water membrane at valleys and eaves matters in our wet climate |
| Shingles or roofing material | The visible roof and its warranty | Shingle line and grade drive both price and lifespan |
| Flashing and ventilation | Metal at chimneys, valleys, vents, and airflow | Often where leaks and heat problems start if done cheaply |
| Labour | The crew's time and expertise | The bulk of the cost on most jobs |
| Permits and cleanup | Permit fees and final site cleanup | A sign of a company that does things properly |
Tear-Off and Disposal
A full replacement removes the old roof down to the deck. This lets the crew inspect the wood underneath and start clean. Some quotes instead propose roofing over the existing shingles, which is cheaper up front but hides the deck and shortens the life of the new roof. If two quotes differ a lot, check whether one is a roof-over.
Materials
The shingle line, underlayment, flashing metal, and fasteners all appear here. Architectural shingles cost more than basic 3-tab products but last longer and resist wind better. A good estimate names the specific products so you know exactly what you are getting.
Labour
Labour is usually the largest single cost. It reflects the crew's time, skill, and the complexity of your roof. A steep, multi-level roof with several valleys and chimneys takes more labour than a simple one, even at the same square footage.
Permits and Inspections
Roofing work in Richmond and across Metro Vancouver may require a permit depending on the scope. A reputable estimate accounts for permits rather than quietly skipping them. Before work begins, a roof inspection establishes the starting condition and helps the quote reflect reality.
What a Good Estimate Spells Out
A thorough quote should clearly state:
- The full scope, including tear-off or roof-over
- Specific materials by name and grade
- How decking repairs are handled and priced if extra plywood is needed
- Workmanship warranty length, separate from the manufacturer's material warranty
- Payment schedule and rough timeline
- Cleanup, including a magnetic nail sweep of the property
Red Flags to Watch For
- A single lump sum with no breakdown - you cannot tell what is included or compare it to other bids
- No mention of decking repairs - because rotten plywood is common, a quote that ignores it may produce a surprise bill later
- Pressure to sign immediately or a "today only" price
- Vague material descriptions like "good quality shingles" with no product named
- No workmanship warranty - the manufacturer covers the material, but only the installer covers the installation
Comparing Quotes Fairly
Line the quotes up side by side and match the scope before you compare totals. If one is much lower, find the reason: is it a roof-over, a thinner shingle, less plywood allowance, or skipped flashing work? A roof replacement done right the first time usually costs less over the life of the roof than the cheapest bid that cuts corners. For smaller issues, a targeted roof repair may be the better value, and a good roofer will tell you honestly which one you need.
Get the Details in Writing
A verbal promise is hard to enforce, so anything that matters to you belongs in the written estimate or contract. That includes the exact materials, the scope of tear-off and decking work, the per-sheet rate for replacing rotten plywood, both the material and workmanship warranties, the payment schedule, and the cleanup commitment. A written, itemized quote is not just paperwork; it is your protection if expectations and reality drift apart partway through the job. Reputable Metro Vancouver roofers are glad to put it all on paper, because clear documentation protects them too.
Take your time with the document. A roof is a major investment, and a day or two to read the quote carefully and ask questions is always worth it.
Questions to Ask Before You Sign
A few questions clear up most uncertainty: What happens if you find rotten decking? Is the workmanship warranty in writing? Who pulls the permit? How is cleanup handled? Clear answers are a good sign you are dealing with a company that stands behind its work.
Make a Confident Choice
A roofing estimate should give you enough detail to understand exactly what you are paying for. Once you can read the line items, comparing quotes becomes straightforward and the right choice is much clearer.
