Buyer decision

Verdict, fit, and reasons to skip

Decision

Best for

Answer
A named synthetic underlayment is a water-shedding layer beneath approved finished coverings. Handling, weight, tear resistance, exposure, and walking-surface claims must come from that product's records.
Why it matters
Choose the named synthetic underlayment when its instructions, handling, exposure plan, covering system, and price are better for the project than compatible felt or another approved layer.

Decision

Skip if

Answer
Exposure limits, walking surface, laps, cap fasteners, deck preparation, and approved coverings differ by product. A project delay can turn temporary-exposure requirements into a material decision.
Why it matters
GAF Tiger Paw underlayment records define approved uses and installation conditions for the cited layer but do not establish this deck's compatibility, drying path, exposure duration, crew execution, finished covering, removal burden, or project price.

Decision

Choose an alternative when

Answer
Use a named felt or another approved synthetic when Tiger Paw's coverage, fastening, exposure, walking surface, availability, or price does not improve the dry-in plan.
Why it matters
Price GAF Tiger Paw underlayment only after the dry-in role, deck, fastening or adhesion, laps, exposure window, covering compatibility, and alternative layer are held constant.
