This property owner contacted us after his warehouse ceiling began to leak and he had many areas of pooling water, as seen in these pictures. His roof had been repaired many times to no avail and it was time to re-roof the entire surface with TPO (Thermal Plastic Polyolefin) Roofing Systems from GAF. The size of the TPO roll is so large that is allows for barely any seams to be present on the roof, unlike previous modified commercial roofing systems. The white color of the TPO allows for temperatures to be better regulated, saving you money! Now, this homeowner has piece of mind that not only is his roof new and improved, he has a 20 year warranty.
