Frequently asked about flat roof replacement

How long does a flat roof replacement take?

Typical single-family addition or small commercial: 2-5 days. Larger commercial: 1-3 weeks depending on system, insulation strategy, and deck condition. Multi-ply systems (modified bitumen, BUR) take longer than single-ply (TPO, EPDM). Weather is the biggest variable — most installs need a stretch of dry weather.

Which flat roof system should I choose?

TPO is the most-installed single-ply for new commercial — white reflective surface, heat-welded seams, 20-30 year warranty. EPDM is the most-installed for retrofits — black rubber, very forgiving install. PVC excels in chemical-exposure environments. Modified bitumen is a multi-ply system common on residential additions. SPF (spray foam) provides the best insulation but requires periodic recoating. A contractor can match the system to your climate, slope, and budget.

Will replacement address my ponding water problem?

Yes — a proper replacement includes either tapered rigid insulation or sloped sleepers to direct water to drains, plus drain replacement if existing drains are inadequate. Don't accept a replacement bid that re-uses an existing slope that has caused ponding. Demand a tapered insulation plan in the proposal.

Can I do a recoat instead of a full replacement?

If your membrane has 5+ years of useful life left and the substrate is dry, a coating (acrylic, silicone, or polyurethane) can extend life 10-15 years at a fraction of replacement cost. If the substrate has trapped moisture or the membrane has widespread failure, recoating just delays the inevitable. A contractor's moisture survey determines which is right.
