TPO is an excellent roofing system for any climate. TPO, it is said is an advancement and a great improvement to traditional flat roofs that are being explored today. The seams of TPO roofs are welded instead of glued. They are less likely to separate when heated and consistent environmental changes.
The Manufacturer certify the flat roof contractors to install the membrane and in turn honor the warranty. A TPO flat roof material gave a white surface that reflects ultraviolet light and keeps the structure cooler than other options.
Because the system is relatively new, revisions and improvements are happening everyday. This requires flat roof repair contractors addressing shrinkage caused by prolonged exposure to UV rays.
They cause stress on flashing and seams. The warranty on TPO roof systems is 15 to 20 years. The welds of both hand-held and walk-behind welding must be checked. Welding that does not take, must be patched or replaced.
Long and short seams require different welds. A lack of uniformity can cause seams to fail and leaks on the roof. Commercial skylights for flat roofs cannot be welded with walk-behind welders used for long seams.
Short seams are needed for A/C units, drains, vents, and skylights. These areas are welded with a hand-held heat gun. The heat difference between the long and short seams becomes an issue.
Heat-welded seams must be correctly calibrated throughout the day of flat roof installation. The quality of a welded seam is affected by wind, cold, and humid weather conditions. A tool is used to check the seam quality to ensure the welds take.
