EPDM is a heavy rubber roofing membrane that’s mechanically fastened to the decking with treated roofing screws and galvanized roofing plates. EPDM comes in 20' x 100' rolls. Because of the 20' width, fewer field laps are needed. For example, a 20' x 60' building would only require 2 field laps. EPDM can also be cut to fit smaller buildings.

EPDM roofs last 15-20 years, depending on application type. EPDM can be applied in two ways: mechanically sealed or fully adhered.

Here is an example of a mechanically sealed proposal:

To reroof an entire area with one layer of heavy 45-mil EPDM rubber roofing membrane. The membrane is mechanically fastened to the decking with treated roof screws and galvanized roofing plates. All seams are field-lapped 6'' as well as mechanically fastened to ensure no lap separation. All firewall flashings are re-covered with 45-mil EPDM rubber roofing that’s adhered to existing firewalls. All pipes, vents and other roof protrusions are sealed with 60-mil EPDM rubber flashing material or preformed rubber roof boots. The contractor carries all necessary insurance on the building and workmen while the work is being completed.

Here is an example of a fully adhered proposal:

To mechanically fasten a 1/2" ply of high-density recovery board to the roof decking with 3" galvanized roofing plates and treated roofing screws. One ply of 45-mil (also available in 60 & 90 mil) EPDM rubber roofing membrane is fully adhered to the recovery board with EPDM contact bonding adhesive applied to both surfaces. All 6" seams are field-lapped and then sealed with EPDM lap sealant. All firewalls are flashed with 45-mil rubber membrane fully adhered to the walls and finished at the top with a 1½" aluminum termination bar; concrete hit pins are drilled into the masonry. All vents, pipes and chimneys are flashed with EPDM flashing rubber. The contractor carries all necessary insurance on the building and workmen while work is being completed.

David Ness Jr. Construction Co. also offers custom-built commercial gutters and fascia metals for a complete roofing job.
