Flat Roof, Vent Leak Repair Contractor

Why flat roof leaks occur at plumbing vent pipes even in the Valley of the Sun. Plumbing vent and other roof penetrations usually are installed during the original construction using a vent jack that surrounds the actual plumbing pipe vent and is roofed over. Over time these components begin to separate and gap creating opportunities for moisture to enter.

A new restroom, new HVAC units, satellite, cables, etc. Many times the contractors who put the new penetrations in are not roofing contractors and mistakenly not seal the vent areas properly.
