TPO roofing is a single-ply membrane roofing system commonly used on flat and low-slope roofs.
Why It Matters
TPO can be a practical option for roof areas where shingles are not appropriate. Seams, drainage, penetrations, and edge details are critical.
Common Problems
Common issues include seam failure, punctures, ponding water, poor termination details, and improper installation around drains or penetrations.
Building Codes & Industry Standards
TPO roofing should follow manufacturer specifications, applicable low-slope roofing code requirements, and proper membrane installation standards.
