Waterproofing details

Roofing underlayment and flashing: quote details homeowners should verify

Underlayment and flashing details are easy to miss but important for leak risk, warranty clarity, and apples-to-apples roofing quote comparison.

Check a roofing quote

Material names matter

A quote that says only 'underlayment included' is less clear than one that names the product type, layers, and where upgraded waterproofing is installed.

Synthetic or felt underlayment
Ice/water or self-adhered membrane where relevant
Drip edge
Valley treatment

Flashing is a common leak-risk gap

Chimneys, walls, skylights, vents, and roof transitions depend on flashing details. A quote should say whether flashing is replaced, reused, repaired, or excluded.

Questions to ask before signing

These are the kinds of questions the paid report turns into a personalized contractor script based on the quote details you enter.

1

What underlayment product and installation method are included?

This turns vague material language into a comparable scope item.

2

Which flashing items are replaced versus reused?

Reused flashing can be acceptable in some cases, but it should be stated clearly.

3

Are drip edge, valleys, penetrations, and wall transitions included?

These are common leak-risk areas and should not be assumed.
