TPO, EPDM, PVC, modified bitumen, coatings, and spray foam solve different problems. The comparison starts with the existing assembly, slope, drainage, insulation, penetrations, and building use. A membrane name alone does not establish that a roof is ready for a recover or restoration.
Ask what will be removed or retained, how wet materials will be handled, and how edges and equipment will be detailed. If a warranty is proposed, review its actual coverage, exclusions, maintenance requirements, and eligibility. Use the pages below to prepare questions, then share your roof age, leak history, and building use before a recommendation is made.
