Start with the proposed installation
If your roofing estimate includes peel-and-stick underlayment, ask for the exact product name and the planned assembly. Have the contractor show the relevant manufacturer instructions and explain how the product will be used on your roof. Ask what surface preparation and installation records are included. Do not assume the product label alone describes every detail that will matter to a later review.
Put the insurance question to the insurer
If insurance treatment is part of your decision, give your insurer the proposed product and installation information before work begins. Ask what it needs to evaluate the roof and who should provide that documentation. Request its answer in writing. The contractor’s explanation of a product and the insurer’s treatment of that installation are separate questions.
- Does the insurer require a particular report or form?
- Who is qualified to complete the requested documentation?
- Which details need to be photographed before they are covered?
- What installation records should I keep?
- Who can clarify conflicting statements about the proposed work?
Make documentation part of the scope
Ask the contractor who captures photographs, identifies the materials, and provides the completion records. Keep those files with your proposal and any insurer correspondence. If the product or installation plan changes, ask whether the supporting documentation needs to be revised before proceeding. This approach helps you make a decision from the actual project and the insurer’s own requirements, rather than a promise that every peel-and-stick installation automatically receives the same treatment.
Understand the layer beneath the roof covering.
Underlayment sits beneath the visible roof covering as part of the specified assembly. Felt, synthetic and self-adhered products are different categories, not interchangeable promises. Compare the exact product, installation requirements and compatibility with the rest of the proposed roof.
Understand how the layers connect
The underlayment, roof covering, flashing and edges must be considered together. Ask how the selected system handles valleys and penetrations. If an upgrade is offered, request a clear explanation of the assembly change and the added work.
