Punctures, open seams, damaged flashing, and localized membrane wear can allow water into a TPO roof even when the rest of the system remains serviceable. Interstate Roofing can inspect the membrane, locate the failure, and complete targeted repairs to restore waterproofing and protect the roof assembly.
A TPO roof may need replacement when membrane deterioration is widespread, leaks recur in multiple areas, or trapped moisture and aging components make continued patching impractical. We can evaluate the existing low-slope roof and install a new TPO system with attention to seams, penetrations, edges, insulation, and drainage.
TPO, or thermoplastic polyolefin, is a single-ply roofing membrane used on flat and low-slope roofs. Sheets are joined with heat-welded seams to create a continuous weather-resistant surface. Light-colored TPO also reflects solar heat, which can help reduce heat gain at the roof.
TPO is widely used on flat and low-slope buildings because it combines waterproofing performance with a relatively simple single-ply system. Benefits include:
Low-slope roofing leaves little margin for installation mistakes, especially in Washington’s wet climate. Interstate Roofing brings decades of regional experience and a full-service approach to TPO repair and replacement.
