Topping It Off: A Gas Station’s Compromised EPDM Roof is Revitalized with an SPF System

Before winding through the Inland Empire and making a gradual eastward turn toward Las Vegas, Interstate 15 slices through Escondido, California. On the southern edge of the city, which is just north of San Diego, a heavily trafficked gas station adjacent to the highway was in need of a roof rehabilitation in early 2012. It was a classic case of underperforming roofing products being replaced with a spray foam roofing system.

The facility is larger than your average gas station. In addition to gas pumps and a convenience store, the station houses a Quiznos Subs restaurant, seating and all. To facilitate the operation of the restaurant and the convenience store, the gas station’s roof supports numerous mechanical units that handle the interior conditioning, refrigeration for cold storage and the ventilation for the restaurant’s oven. Additionally, the roof features a satellite dish, numerous penetrations, all of which is enclosed by a braced, parapet-like metal barrier. The roof, much like the gas station itself, is a busy place. However, the existing roof system at the time, which consisted of an EPDM (ethylene propylene diene monomer) rubber, was not facilitating proper drainage; the roofing system was compromised and had bubbled up in several areas. Further compounding the issue was the fact that the roof has only two drainage locations. While the drainage situation led only to minor leakage issues, the fact that the building housed an eating establishment meant the problems had to be addressed thoroughly; the gas station needed to be re-roofed.
