How to Read a Roofing Estimate: 7 Things That Should Be in Writing

When one estimate is a lot lower than the others, it is tempting to take it and move on. But a roof is a system, and a low number often means something was left out. The best way to compare bids is to read them line by line, and these are the seven things to look for.

1. The scope of work

The estimate should say whether the old roof will be torn off completely or covered over, and which parts of the house are included. If it just says "replace roof," ask for detail.

2. Materials by name

Look for the shingle manufacturer, product line, and color, along with the underlayment, drip edge, and ventilation products. Vague wording makes it hard to compare bids or know what is actually going on your house.

3. Flashing and ventilation

New flashing at chimneys, walls, valleys, and vents should be part of the plan, not an afterthought. So should the ventilation approach, since it affects how well the roof and attic work together.

4. How decking repairs are handled

Nobody can see the wood beneath the shingles until the old roof is off. A good estimate explains how damaged decking will be priced, whether by the sheet or by the foot, so there are no surprises later.

5. Cleanup and disposal

The estimate should say who hauls away debris and whether the property gets a magnetic nail sweep at the end. It is a small detail that says a lot about how the job will be run.

6. Timeline and payment terms

You should know the expected start window, how long the work should take, and when payments are due. Be cautious of any bid that asks for the full amount before work begins.

7. Warranty details

Ask what is covered by the manufacturer and what is covered by the contractor's own workmanship, and for how long. Get both in writing so you know who to call if something goes wrong.
