Questions to Ask a Roofer Before Hiring

The best question is not always “Is this a good roofer?” A more useful question is often: What, exactly, has this contractor promised in writing?

Before hiring a roofing contractor, read the estimate or proposal closely and make a list of anything that is assumed, conditional, vague, or missing. A verbal answer can be helpful, but if the answer affects scope, price, warranty, or responsibility, ask for it to be reflected in the written agreement.

1. What exactly is being removed?

Ask whether the proposal includes removal of the existing shingles, how many existing roof layers are expected to be removed, and what happens if the actual conditions differ from what the contractor expects.

A phrase such as “roof replacement” does not always explain every part of the tear-off. If removal of old underlayment, flashing, or other existing materials matters to you, make sure the written scope says what will be removed and what may remain.

2. What roofing product is actually being installed?

Ask for the manufacturer and product line, not just a broad description such as “architectural shingles.” If the quote includes optional upgrades, confirm which option is included in the total you are considering.

Color can usually be finalized later, but the product line and roofing system should be clear enough that you can compare one contractor's proposal with another.

3. What happens if damaged roof decking is found?

Decking is one of the most important places for a proposal to be specific because the full condition may not be visible until the old roof is removed.

Ask whether any replacement decking is included, how additional decking will be priced, what unit is used for that price, and whether the contractor must get your approval before doing additional work.

4. What underlayment and ice-and-water protection are included?

Ask what underlayment is included and where ice-and-water protection will be installed. A quote may name the material but say very little about placement.

The goal is not to turn yourself into a roofing designer. It is to understand the written system you are buying and to identify differences between proposals before assuming two bids include the same work.

5. Which flashing and roof penetrations will be replaced?

Flashing details are easy to overlook in a proposal. Ask what happens at walls, roof-to-wall transitions, chimneys, skylights, vents, and plumbing penetrations that apply to your roof.

If the contractor plans to reuse some existing flashing and replace other pieces, ask them to identify that distinction in writing. The same applies to pipe boots and other penetration components.

6. How is roof ventilation being handled?

Ask whether the project includes changes to ridge vents, box vents, intake ventilation, or other ventilation components. If the contractor is leaving the existing ventilation arrangement unchanged, that is useful to know too.

You do not need the quote to become an engineering report. You do want enough written detail to know whether ventilation work is included in the price.

7. Who is responsible for permits, and are permit costs included?

A proposal may list a permit amount without clearly saying who will obtain the permit, or it may say the contractor will handle permits without stating whether the fee is already included in the contract price.

Ask both questions separately: Who handles the permit? and Is the permit cost included in the quoted total?

8. What cleanup, disposal, and property protection are included?

Ask how removed roofing material will be handled, whether dumpster or disposal costs are included, and what final cleanup is part of the job.

It is also reasonable to ask how the contractor plans to protect landscaping, siding, driveways, patios, and other areas that could be affected by tear-off and material handling. The written proposal may not need to describe every job-site procedure, but major cost responsibilities should not be left to assumption.

9. What is the payment schedule?

Do not look only at the final contract price. Ask when each payment is due and what event triggers it: signing, material delivery, start of work, completion, final inspection, or another milestone.

Two contractors offering the same total price can expose the homeowner to very different payment timing. Make sure the written percentages or dollar amounts add up to the contract total and that you understand how much will be paid before the work is complete.

10. What can increase the final price?

Look for allowances, unit prices, optional work, exclusions, hidden-damage language, and other conditions that can change the amount due.

Ask how additional work is authorized and documented. If plywood, structural repairs, flashing repairs, or other discoveries have separate pricing, make sure you understand both the price and the approval process before work begins.

11. What warranties are included?

Ask the contractor to distinguish between the manufacturer's material warranty and the contractor's workmanship warranty. They are not the same thing.

For each warranty that matters to the proposal, look for the term, who provides it, what work or materials it covers, and any registration or documentation the homeowner is expected to receive after the job.

12. What is the expected start window and project duration?

A stated duration such as “one to two days” answers how long the work may take once it starts. It does not necessarily answer when the project will begin.

Ask what controls scheduling after signing or material delivery, how weather delays are handled, and how you will be notified if the planned start date changes.

13. What is specifically excluded from the quote?

Exclusions can be just as important as included work. Read them carefully and ask about any item that could reasonably become necessary during the project.

A clear exclusion is not automatically a bad term. It is information you need in order to compare bids fairly and understand which costs remain your responsibility.

14. Can the answers be added to the written proposal?

This is the question that ties the others together. If a contractor gives a clear verbal answer to something important, ask whether the estimate, proposal, or contract can be updated to reflect it.

Written clarity makes it easier for both sides to know what was agreed to. It also makes competing quotes much easier to compare on scope rather than price alone.

A quick roofing estimate checklist

Before signing, you should be able to locate or deliberately confirm the items that apply to your project:

• Removal and tear-off scope
• Shingle manufacturer and product line
• Decking inspection and replacement pricing
• Underlayment and ice-and-water protection
• Flashing and roof-penetration work
• Ventilation work
• Permits and permit costs
• Cleanup and disposal
• Total contract price
• Payment schedule
• Change-order or additional-work pricing
• Manufacturer and workmanship warranties
• Expected start window and project duration
• Major exclusions and owner responsibilities

Do not compare roofing quotes by price alone

A lower total can represent a better deal, a narrower scope, different materials, different allowances, or simply a proposal that leaves more details unresolved. Until the scopes are normalized, the bottom-line numbers may not be directly comparable.

That is why the useful sequence is: understand each written proposal, identify what is unresolved, ask for clarification, and then compare.
