Like everything in life, your metal building's roof is going to get tired, old and worn. It happens to them all. Over time, Mother Nature's destructive forces, long-term UV exposure and continuous expansion and contraction has left your metal roof rusty, leaking and deteriorating.
No "Miracle From a Bucket" Here -- You Get A REAL Roof.As the leading manufacturer of TPO based roofing membranes, Stevens Roofing Systems has engineered a durable, light-weight roofing membrane system specifically for retrofitting tired, aging, metal roof decks regardless of whether it is a standing seam, flat seam, or corrugated metal roof.
Easy Three Step Installation Process1. From the deck up we start with an approved polyisocyanurate, extruded or expanded polystyrene insulation that has been cut to fit in the flutes of the existing metal roof deck. This material is loose-laid between the standing seams of the existing roof deck, providing additional R-value to the building as well as structural support for the insulation that will be installed over the top.
2. Next we mechanically attach a cover board or insulation board over the top to provide a uniform and flat substrate for the roofing membrane. Stevens can provide polyisocyanurate, extruded or expanded polystyrene insulation, in thickness ranging from 1 to 4 inches (25.4-mm, 101.6-mm) depending on your specific R-value and energy savings requirements.
3. Last, the Stevens EP™ membrane is installed over the insulation and mechanically fastened directly to the supporting purlins using a specially designed, self-tapping purlin fastener and seam plate. Membrane widths of 64.5-, 70.5- and 76.5-inches (1.63-m, 1.79-m, 1.94-m) can accommodate typical 4 and 5-foot (1.21 and 1.52-m) purlin spacing and any variances. When fastened at 12-in. (304.8-mm) on center using Stevens Purlin Fasteners and a Stevens 2-3/8-inch (60-mm) Barbed Metal Seam Plate, the system is Factory Mutual approved for a 1-90 wind uplift classification rating. Additional wind uplift ratings are also available. Consult the Stevens Roofing Systems Technical Department or the latest FMRC Approval Guide for details.


When it comes to long-term weathering, Stevens Roofing Systems has really got you covered too, because Stevens EP™ membranes for Metal Roof Retrofit applications are available with a variety of 15- and 20-year warranties vs. the typical 5- to 10-year warranty that most roof coatings offer. Contact Stevens Roofing Systems for complete details.
