How to Read a Roofing Estimate in Maryland

A roofing estimate is the most important document you'll sign this year — and most homeowners are handed it with zero instruction on how to read it. A good estimate tells a complete story: what's being done, with what materials, in what order, for exactly how much, and what happens when the unexpected shows up. A bad one hides behind a single lump-sum number and a handshake. This guide shows you how to tell the difference, line by line.

If you're comparing bids right now, pair this with our roof replacement cost factors guide — it explains why prices differ, and this guide explains how to verify that the price you're quoted actually covers the work.

Line Items That Should Be on Every Estimate

A professional Maryland roofing estimate should itemize at least the following. If any are missing, ask — the answer (or the silence) is informative:

• Scope of work. Repair or full replacement? Which slopes or the whole roof? It should say so in plain language.
• Tear-off details. How many existing layers will be removed, and confirmation the tear-off goes to the decking. Dump fees should be included.
• Decking replacement terms. A per-sheet price for replacing rotted or damaged decking, stated before work starts, plus how the crew documents what they find (photos, kept sample sheets, your approval). Decking is the one thing nobody can price until tear-off — the per-sheet rate is how an honest contractor handles it.
• Underlayment and ice-and-water shield. What type of underlayment, and where ice-and-water shield goes (eaves, valleys, penetrations — critical in Maryland's freeze-thaw winters). “Underlayment included” without a type named is a gap.
• Shingle specifics. Manufacturer and product line (for us, the TAMKO system), color, and style — not just “architectural shingles.” Our shingle tier guide explains what the tiers mean.
• Starter shingles and ridge caps. These are part of the system, not extras. They should be listed.
• Ventilation work. What intake and exhaust are being installed, repaired, or left as-is — ridge vent, soffit vents, baffles. Silence here is a red flag; see our ventilation mistakes guide.
• Flashing details. Chimney flashing (step + counter-flashing), skylight flashing or replacement, vent pipe boots, valley treatment. Each penetration should be addressed by name.
• Permits. Confirmation the contractor pulls the permit for your Maryland county or municipality, with the cost included.
• Cleanup and protection. Landscaping protection, daily cleanup, and a magnetic nail sweep at the end. This is part of a professional job, not a favor.
• Warranty terms. What the manufacturer covers and what the contractor covers for workmanship, in writing — with durations stated. Vague “lifetime warranty” language with nothing behind it deserves questions (see our roof warranties guide).
• Payment schedule. Deposit amount, progress terms, and final payment tied to completion and your satisfaction — never full payment upfront.
• Timeline. Start window and expected duration, plus what happens with weather delays.

What MHIC #24398 Means for You

In Maryland, any contractor performing home improvement work — including roofing — must be licensed by the Maryland Home Improvement Commission (MHIC). Our license number is MHIC #24398. Here's what that means in practical terms for a homeowner:

• It's verifiable. You can look up any MHIC number with the state to confirm the license is current. Do this for every bidder — it takes two minutes.
• It's a baseline, not a gold star. Licensing means the contractor met the state's requirements; it doesn't tell you about craftsmanship or honesty. Treat it as a filter: no MHIC number, no bid. But don't stop there.
• It should be on the estimate. A Maryland contractor's MHIC number belongs on their paperwork, their website, and their trucks. If it's missing from an estimate, ask why.

Beyond the license, ask for proof of general liability insurance and workers' compensation. If a worker is injured on your property and the contractor carries no coverage, the liability picture gets ugly fast. Certificates should be current and in the company's name — not a subcontractor's, unless the subcontractor relationship is disclosed.

Red Flags in an Estimate

Some estimates don't need a second reading. Watch for these:

• A single lump-sum number with no line items. You can't compare “$14,000” against “$18,000” when you don't know what either one includes. The cheaper bid usually just left more out.
• No mention of decking. A replacement estimate that never discusses what happens if the deck is rotted is incomplete — you'll discover the pricing when the crew finds it, which is the worst possible time.
• Full payment before work starts. A reasonable deposit is normal. Full payment upfront is not — it removes your only leverage.
• Today-only pricing. “This price expires tonight” is a pressure tactic, not a material cost reality. Shingle prices don't change overnight; salespeople's commissions do.
• Insurance-contingent scope. If the estimate reads like it was written for your insurance adjuster instead of for you — scope that expands or shrinks based on the claim — remember who the customer is. You are.
• Storm-chaser paperwork. Out-of-state plates, a PO box instead of an address, no local references, and a push to sign before the adjuster arrives. Maryland is a wind market — after every big storm, the chasers arrive. Our storm damage updates guide covers how to handle the aftermath properly.
• Verbal promises that aren't in writing. “Oh, we'll take care of the gutters too” means nothing unless it's on the page. If it matters, it's written. If it's written, it matters.
• No attic inspection mentioned. Nobody can assess ventilation or decking from the driveway. An estimate built without attic access is built on assumptions.

Questions to Ask Before You Sign

Take this list to every estimate review. The quality of the answers matters more than the price at the bottom:

• Who will actually be on my roof — your crew or a subcontractor? Who supervises?
• What's your per-sheet decking replacement price, and how do you document and approve it with me?
• Exactly which underlayment and ice-and-water shield products are you installing, and where?
• What ventilation changes are included, and why?
• How are my chimney, skylights, and pipe penetrations being flashed or replaced?
• Do you pull the permit, and is the fee included?
• What does your workmanship warranty cover, for how long, and is it in writing?
• What's the payment schedule, and when is final payment due?
• How do you protect my landscaping and handle cleanup — and do you do a magnetic nail sweep?
• Can I see your MHIC license and current insurance certificates?
• Can you give me two or three recent local references I can call?

A good contractor welcomes these questions. They're the same questions we'd want asked about us. A contractor who gets defensive, vague, or rushed when you ask them is answering the most important question of all.

How to Compare Multiple Estimates Fairly

Lay the bids side by side and normalize them: same scope, same materials, same line items. The most common reason estimates differ isn't labor rates — it's scope. One includes ice-and-water shield at the eaves; another doesn't. One prices decking replacement; another pretends the deck is fine. One includes ventilation correction; another leaves your blocked soffits exactly as they are.

Once scopes match, the remaining differences are usually labor quality, supervision, and warranty backing — which is exactly where you want to be comparing. The cheapest normalized bid from a licensed, insured, referenced contractor is a fine choice. The cheapest un-normalized bid is a gamble where you find out what you bought after the crew leaves.

And one more thing: beware the bid that's dramatically lower than all the others. In roofing, there are no secret efficiencies that cut 30% off a proper job. There are only missing line items, cheaper materials than specified, and corners you won't see until the first bad winter.
