Woodridge Middle School – Peninsula, Ohio

With a tight schedule to meet, Woodridge Middle School was relying on SOPREMA’s SENTINEL products to do the job. The previous shingle and PVC roof was replaced with SOPRA-ISO, and tan SENTINEL P150 HFB. The gutters were then lined with ALSAN RS 222 primer and ALSAN RS 230 Flash.

Lancaster Material Distribution Center – Lancaster, Texas

In May 2017, the Lancaster Material Distribution Center needed a new roof. While the original SOPREMA asphalt system was in decent shape, it was nearly 25 years old and at the end of its life. Through value engineering, it was decided that the existing system would be left in place to save cost. SOPREMA products were selected to re-roof this project due to the proven durability of the existing roof. The system that was installed included ELASTOCOL® 500, COLVENT® Flam, ELASTOPHENE® Flam LS FR GR, SOPRALENE® Flam 180 and SOPRALENE Flam 180 FR GR.
