Is spray polyurethane foam or TPO a better choice for a flat roof in Gilbert?
Both are viable in Gilbert's desert climate, but they serve different situations. Spray polyurethane foam with a reflective elastomeric topcoat excels at adding insulation value and conforming to complex roof geometry, and it restores well without full tear-off. TPO offers strong seam strength and documented longevity on simpler flat decks. The best choice depends on deck condition, existing insulation, and whether drain relocation is needed.
How often should a flat roof in Gilbert be inspected?
At minimum, a professional inspection should occur once annually — ideally before monsoon season in early summer. After any hailstorm or high-wind event, an additional inspection is warranted because even small impact punctures in a membrane can admit water that migrates laterally before showing as an interior stain. Early detection keeps repair scopes small.
What should a flat-roof proposal in Gilbert include that a standard quote might omit?
A thorough flat-roof proposal should address drain condition and sizing, parapet cap flashing, equipment curb flashing, and penetration seals — not just the field membrane. In Gilbert's monsoon environment, weak points at transitions and curbs are where failures originate. Confirm that the proposal specifies material weight per square, seam method, and whether an infrared moisture scan of the existing insulation is included before any overlay is applied.
