A major manufacturer of single ply roofing systems had recently all but completed a large PVC roofing installation for a confidential Silicon Valley client when there was an inquiry from the roofing contractor. The interface of concrete curbs and supports with the single ply roof system presented a detailing challenge. Enter the Sikalastic RoofPro 641 Lo VOC fluid applied roofing and waterproofing system.

Featuring a low odor, no mix, and virtually no waste system comprised of a conformable Sika Reemat fiberglass reinforcement and the Sikalastic EP Primer, Sika was able to effectively address the challenging condition and offer a fully warrantable tie in to existing single ply PVC roofing. Sikalastic-641 Lo-VOC is compatible with nearly any other existing roofing system - TPO, BUR, EPDM, HRA, to name but a few. Whether detailing or full coverage, new or existing roofs, Sikalastic RoofPro is your easily employed, globally proven solution. Contact your local Sika Representative and find out more.
