Composite decking has come a long way over the past two decades. Trex has evolved it by engineering the most significant breakthrough in composite technology—the Trex high-performance, weather-resistant shell. Without it, early-generation composites don’t come close to the fade & stain resistance that Trex high-performance boards guarantee. And not just for the first year, but for 25 long, glorious years. And unlike PVC decking, which is mostly produced from virgin plastic, the ultra-green Trex board is made with 95% recycled materials and eco-friendly manufacturing processes.
When locating a leak, remember that water can’t run uphill, so leaks on a pitched roof cannot be below where you see evidence of a leak. Water can enter through exposed nail holes or an area with missing shingles, traveling over old layers of roof and roofing felt until it reaches a gap or tear that allows it to penetrate to the roof deck. From there, it may run over the plywood until it crosses a joint – whereupon it may resume its journey along a rafter or the underside of the decking.
