How to compare roof replacement quotes in Connecticut: a checklist
To compare roof replacement quotes in Connecticut, check each quote for the same line items: full tear-off, the exact shingle line, underlayment and ice and water shield, flashing, ventilation, decking included and the price per extra sheet, the permit, cleanup, the workmanship warranty, and the schedule. Then check the contract for what Connecticut requires: the contractor’s registration number, start and completion dates, and your right to cancel. When two quotes for the same house are thousands apart, it’s usually because they cover different work.

The checklist
| What to check | What to look for | Ask the contractor |
|---|---|---|
| Tear-off | All old roofing removed down to the deck, with disposal included | Are you removing every layer, and is the dumpster in the price? |
| Shingles | The exact manufacturer, product line and color | Which shingle line, exactly? |
| Underlayment | Synthetic underlayment over the whole roof | What goes under the shingles? |
| Ice and water shield | Where it goes: eaves, valleys and penetrations, or the entire roof | How far up from the eaves does it run? |
| Edges and ridge | New drip edge, starter strip, and ridge and hip cap | Is the drip edge new or reused? |
| Ventilation | Ridge vent, or existing vents kept and repaired | How will the attic be ventilated? |
| Chimney and skylight flashing | New flashing, or existing flashing repaired | Is chimney flashing replaced or reused? |
| Pipe boots and vents | Every boot and vent replaced, or only damaged ones | Are all pipe boots new? |
| Decking | How many damaged sheets are included, and the price for each extra sheet | What happens if you find rotten decking? |
| Second layer | The added cost if a second layer of shingles is found | What if there are two layers? |
| Permit | Who pulls the building permit and schedules the town’s sign-off | Is the permit in your price? |
| Cleanup | Landscaping protection, daily cleanup and a magnetic nail sweep | How do you pick up nails? |
| Warranty | The workmanship warranty in years, in writing, plus the manufacturer’s warranty | How many years is your workmanship warranty? |
| Schedule | A start date and a completion date | When would you start, and when will you finish? |
| Payment | The deposit, when it’s refundable, and when the balance is due | What do I pay up front, and when? |
What Connecticut requires in your contract
- The contractor’s home improvement registration number. Anyone who contracts for home improvement work in Connecticut must be registered with the Department of Consumer Protection, and you can look up any registration online.
- A written contract signed by you and the contractor, with the full scope of work.
- Start and completion dates.
- A notice of your right to cancel.
Why two roof quotes for the same house can be thousands apart
The biggest differences are usually scope, not price: one quote removes every layer and another doesn’t, one replaces the chimney flashing and another reuses it, one includes ice and water shield over the whole roof and another only at the eaves, one includes decking and another bills every sheet. Line the quotes up item by item before comparing the totals.
Comparing quotes with ChatGPT, Claude or Gemini
An AI assistant is a good way to line quotes up. Paste in each quote along with this checklist and ask: “For each quote, which items on this checklist are included, which are missing, and which aren’t clear? What should I ask each contractor?”
