Dan came out and I met with a very friendly, helpful, & considerate representative....The roof was done correctly and looked very nice.  The gutter crew came and went in 1 day and everything looks great!  I will definately recommend Petra Roofing Company.

The Duro-Last Roofing System
 
The Duro-Last Roofing System is a complete mechanically-attached roofing system with all accessories included. It can be applied directly over many existing flat roofs with its minimal prep work and can eliminate costly tear off fees.  Duro-Last is leak-proof, virtually maintenance-free, and resistant to fire, chemicals and high winds.  It is the only flat roof material to warranty against ponding leaks on trouble areas that many flat roofs have.
 
In the commercial roofing industry, reflectivity has been the dominant discussion point for several years, and the Duro-Last Cool Zone roofing system has set the standard for single-ply reflectivity and the resulting energy savings.
