This photo shows a typical parapet wall with SPF and coating applied up the wall to the top of the plate. Galvanized sheet metal was formed and attached as a metal parapet cap with a drip edge. This field detail is topped with clay tile as part of the architectural finish needed. The use of metal as a parapet cap and counterflashing is similar to detail SPF-15 that can be found in The NRCA Roofing and Waterproofing Manual, Fifth Edition.

In this photo, you can see how an aged SPF base flashing has survived differential movement in the nonwall supported deck. Note the elastomeric sheets totally have parted across the deck portion of the expansion detail. The copper counterflashing has pulled apart at the joint. This 1988 SPF installation showed no distress and continues to function. This deck runs along a second-story wall that is not shown.

This photo illustrates how a higher roof transitions to a slightly lower roof that required a short transition wall to the adjoining lower roof. A light-gauge metal wall panel and cap previously formed this transition. This detail was installed in 1977 and recoated in 2002.

A roof-to-roof transition is shown in this photo, which details how SPF was used to solve a difficult tie-in for two roof systems. The existing metal flashing detail was covered with SPF and coated. The SPF transition detail also makes a right angle and continues to the right as a tie-in to the metal roof system that was added to the existing structure. The SPF tie-in was installed in 1991.

This photo shows a large existing warehouse complex that had been reroofed with SPF in 1991. The existing metal roof and interior gutter system were overlayed with 1 1/2 inches (38 mm) of SPF and coating. The existing metal flashing system was secured and covered with SPF. No new metal flashings or counterflashings were added. The interior gutters also were covered with SPF as shown.

A complete roof-and-wall transition with SPF is shown. No metal flashing has been used on this 1997 installation. All the pre-existing metal flashing now is encased by SPF. No new metal was used. The divider wall between the two lower roof systems has been covered with SPF and coating to complete the system.

The large lower main roof of this distribution center is broken up by a three-story masonry block wall. As shown in the photo, the expansion joint in the block wall is active. The SPF reroofing material covers all pre-existing metal flashing. The SPF flashing now reaches above the original metal counterflashing with the coating going above the SPF by at least 4 inches (102 mm). There are no cracks or spalling of the SPF; the coating is functioning as a counterflashing over the SPF at the top of the cant as shown.

In some instances, the metal cap flashing system completely is covered by the SPF system with no loss in performance. This photo shows a low masonry parapet wall and metal cap system covered with SPF and coating along the perimeter of a 1998 installation.

Both low and high equipment support curbs were observed as shown in Photos 9 and 10. In this photo, the high curb appears to have been extended up with a slightly smaller curb from the original base and flashed with SPF and coating.
