How to Compare Roofing Quotes

Why do roofing quotes look so different?

You called three reputable roofers, walked them through the same project, and got back three quotes that look nothing alike. One is a single number on a one-page document. One is itemized to a dozen lines. One is a 4-page proposal with material spec sheets. The prices are wildly different.

This is normal. It’s also the reason most homeowners pick the wrong contractor.

Roofing quotes look different because contractors organize them differently — not because the underlying work is different. Some bundle materials with labor into one line. Some itemize every shingle bundle. Some include cleanup and permit; some leave them off entirely (and add them as line items on the final invoice). Some quote the bare-minimum material spec; some quote a premium tier. Until you normalize the scope, comparing the prices is meaningless.

The good news: there’s a fixed set of items that should appear on every legitimate roofing quote in Massachusetts. Once you know what to look for, the comparison becomes simple.

The 15 line items every roofing estimate must include

Print this list. Take it to every estimate. If a line item isn’t on the quote, ask the contractor to add it before you compare prices.

Materials (6 items)

1. Shingles — brand, product line, color, and quantity (in squares). “Architectural shingles” isn’t enough. We need to see “CertainTeed Landmark Pro, Weathered Wood, 28 squares.”
2. Underlayment — synthetic or 15-lb felt. Synthetic lasts longer, holds up better in tear-off, and is what every reputable contractor specs in 2026. Felt is acceptable but cheaper for a reason.
3. Ice & water shield — Massachusetts code (780 CMR) requires coverage 24 inches past the interior of the exterior wall. The quote should specify the linear footage and location (eaves, valleys, around penetrations, etc.). More coverage in valleys and around chimneys is better.
4. Drip edge — required by code on all eaves and rakes. The material (aluminum vs. steel) and color should be specified.
5. Flashing — step flashing, counter flashing, chimney flashing, valley flashing. The quote should specify whether each type is being replaced new or reused. Best practice is new — reusing old flashing is one of the most common shortcuts.
6. Pipe boots / jack flashing — every plumbing vent and exhaust penetration on the roof has a rubber boot that should be replaced during a roof job. Skipping this is the #1 cause of leaks on otherwise-new roofs.

Labor & logistics (5 items)

7. Ventilation — ridge vent linear footage and soffit intake. A balanced ventilation system isn’t optional — it’s what keeps the manufacturer warranty valid and your attic from rotting. Most older roofs have inadequate ventilation; an honest contractor will note that and quote the upgrade.
8. Tear-off and disposal — number of layers being removed and the method. Massachusetts allows up to two layers of asphalt on a residential roof; tearing off both layers down to the deck is the only way to inspect for rot and get the manufacturer warranty.
9. Dumpster, debris removal, and magnetic nail sweep — the dumpster fee and a magnetic sweep of your driveway and lawn for fallen nails should be included, not added later.
10. Permits — required for every full replacement in Massachusetts. Fees run $100–$500 depending on the city or town. The permit should be pulled by the contractor (in their name) and included in the quote.
11. Decking repair pricing — your contractor won’t know how much rotted plywood/OSB is under your shingles until tear-off. The quote should include a per-sheet price (typically $75–$150 per sheet of plywood, installed) so there’s no surprise upcharge mid-project.

Protection & warranties (3 items)

12. Property protection — tarps over landscaping, covers for AC units and walkways, plywood over windows where debris might fall.
13. Workmanship warranty — duration in years and what’s specifically covered. Reputable contractors offer 10+ years on workmanship.
14. Manufacturer warranty — tier and duration. Standard is 25–30 years; manufacturer-certified installers can offer enhanced warranties (50-year non-prorated material, 25-year workmanship) at a small upcharge.

Process (1 item)

15. Payment schedule — deposit amount, milestone payments (if any), and final-payment terms. See Payment Structures below for what’s normal.

The apples-to-apples framework

Once you have three quotes, here’s how to actually compare them:

1. Make a spreadsheet. Rows = the 15 line items above. Columns = each contractor. Fill in what each quote specifies.
2. Find the gaps. If Contractor A specs synthetic underlayment and Contractor B specs felt, that’s not a price difference — that’s a scope difference. Note it.
3. Normalize the scope. Email or call each contractor and ask them to revise their quote so all three use the same material tier (architectural shingles, synthetic underlayment, new flashing, ridge vent, etc.).
4. Compare the revised numbers. Now the price difference reflects what you’re actually paying for: crew quality, warranty depth, manufacturer certifications, overhead.
5. Don’t pick on price alone. The cheapest of three matched quotes isn’t always the right call. Look at certifications (GAF Master Elite, CertainTeed SELECT ShingleMaster), references, and how the contractor communicated through the quoting process.

Red flags that should eliminate a contractor

Some red flags are dealbreakers — meaning you should stop considering that contractor entirely, regardless of price. The short list:

• One lump-sum price with no breakdown. You have no way to compare scope. You also have no recourse if they upcharge mid-project.
• No mention of permits. Permits are legally required in Massachusetts. A contractor planning to skip the permit is also planning to skip an inspection.
• No proof of insurance. Workers’ compensation AND general liability — both. If a worker gets hurt on your property and the contractor doesn’t have workers’ comp, the claim can come back to you.
• Demanding more than 50% upfront. 10–30% is standard for material ordering. Anything more is either a cash-flow problem or worse.
• “I’ll call my manager” pricing games. Theatrical discounts (“normally $30,000, but if you sign today...”) are sales tricks, not honest pricing.
• No physical roof inspection before quoting. A satellite-only quote is a guess. Find the rotted decking later, double the price.
• Unusually low price (30%+ below the others). The contractor is either planning to cut corners on materials or to upcharge you for “unforeseen” work mid-project. There’s no third option.
• Vague material descriptions. “Premium shingles” isn’t a spec. “CertainTeed Landmark Pro” is.
• No mention of ventilation. Either they’re planning to ignore it (warranty-voiding) or they’re going to surprise you with a $1,500 line item later.

Questions to ask every contractor

Beyond the line-item checklist, ask each contractor the same questions. Their answers — and how they answer — tell you a lot.

About the company

• Are you licensed and insured in Massachusetts? Can I see proof of workers’ comp and general liability?
• How long have you been in business? Where’s your physical office?
• Are you manufacturer-certified (GAF Master Elite, CertainTeed SELECT ShingleMaster, Owens Corning Platinum, etc.)?
• Can you give me 5–10 recent local references — projects done in the last 12 months?
• Do you use your own crews or subcontract the labor?

About the quote

• Walk me through every line item.
• What brand, product line, and warranty tier of shingles?
• How many linear feet of ice & water shield, and where is it being installed?
• What underlayment — synthetic or felt?
• Are you replacing all flashing, or reusing any?
• What’s the ventilation plan — intake and exhaust?
• What’s the per-sheet price for rotted decking found during tear-off?
• Is the building permit included? Will you pull it in your name?
• What’s your cleanup process? Magnetic nail sweep included?

About warranties

• What’s your workmanship warranty — duration and what’s covered?
• What manufacturer warranty tier am I getting?
• Is an enhanced (manufacturer-backed) warranty available? What does it cost extra?
• What voids the warranty?

Understanding warranty types

Roofing warranties confuse almost everyone. Here’s what each one actually covers.

The big one to understand: a standard manufacturer warranty does not cover labor. If a shingle fails in year 12, the manufacturer will send you replacement shingles — but you’ll pay a contractor to install them. An enhanced warranty covers both material and labor, which is why it’s worth the modest upcharge if you plan to be in your home long-term.

Payment structures: what’s normal

There are two normal ways a Massachusetts roofing contractor structures payment:

Simple two-payment

• 10–30% deposit at signing (covers material ordering)
• Balance due at completion / final walkthrough

Milestone

• 10% at signing
• 30% on material delivery
• 30% at midpoint (typically tear-off and dry-in complete)
• 30% at completion / final walkthrough

Either is fine. What’s not fine:

• Anything over 50% upfront.
• 100% upfront. (We’ve seen this. Don’t do it. Once they have 100% of your money, your project competes with every other project for crew time.)
• Cash-only. Pay by check or credit card so there’s a paper trail.
• No final-walkthrough hold. Always hold 10–30% until you’ve walked the property and confirmed cleanup, that the magnetic nail sweep was done, and that any decking repairs match what was billed.

Massachusetts-specific notes

A few details that matter specifically for Massachusetts homeowners:

• Ice & water shield is code. 780 CMR requires coverage at least 24 inches past the line of the interior of the exterior wall. Many older homes have less than that — your new roof will need more.
• Permits are required. Every full replacement needs a permit pulled by the contractor. Fees vary by town ($100–$500 typical).
• Roofing season is short. April through November is the working window. Demand spikes in spring after winter damage, and again in late summer before the season closes. Booking ahead helps.
• Labor costs run higher. Roofing labor in Massachusetts averages roughly 15% above the national baseline.
• Material prices have moved. Asphalt shingle manufacturers raised prices 6–10% in 2025–2026. Steel and aluminum components (drip edge, flashing) have been hit harder by tariff-driven increases. Quotes more than 60 days old should be re-confirmed.

Frequently asked questions

How many roofing quotes should I get?

Three is the standard. Two doesn’t give you enough range to spot an outlier; four or more usually doesn’t change the picture and starts to waste contractor and homeowner time. The point isn’t volume — it’s getting three apples-to-apples quotes you can actually compare line by line.

What should be on a roofing estimate in Massachusetts?

All 15 line items above. The Massachusetts-specific minimums: ice and water shield 24 inches past the exterior wall (per 780 CMR), drip edge on all eaves and rakes, a building permit pulled by the contractor, and a workmanship warranty.

Is the lowest roofing quote usually the best deal?

Almost never. A quote 30% below the others usually means the contractor cut corners — typically by skipping ice and water shield, reusing flashing, using cheaper underlayment, or planning to upcharge you for decking repairs they already know they’ll find. Compare scope before you compare price.

How much deposit should a roofer ask for?

10–30% at signing is normal — that covers material ordering. Anything over 50% upfront is a red flag. Hold 10–30% until the final walkthrough.

What’s the difference between a manufacturer warranty and a workmanship warranty?

The manufacturer warranty covers the materials (defects, premature failure) for 25–50 years and is honored by the manufacturer. The workmanship warranty covers installation errors and is honored by the contractor — which means it’s only as good as the contractor’s longevity. Reputable contractors offer 10+ years on workmanship; some manufacturer-certified installers can offer enhanced warranties that combine both.

Do I need a permit for a roof replacement in Massachusetts?

Yes. Every full roof replacement in Massachusetts requires a building permit pulled from your local building department. Permit fees typically run $100–$500. A reputable contractor pulls the permit (it should be in their name, not yours) and includes the fee in the quote.
