Roof penetrations are the most common source of leaks. Pipes, mechanical equipment, vents, solar panels and lightning protection are examples of penetrations which, in time, will create avenues for water. Repeated cycles of load, heat, cold, moisture, water ponding, and ultraviolet inevitably degrade pitch pans, rain caps, boots and other types of seals aimed at preventing leaks.

The ChemCurb System replaces the old style metal pitch pans with versatile precast curb components, pourable sealant, and structural adhesive/sealant. The system can usually be installed in under 15 minutes and eliminates the need for flashing or mechanical attachment.

The ChemCurb System is designed for use on granulated modified bitumen, PVC, EPDM, PIB, TPO single ply, asphalt, and coal tar B.U.R. Please note TPO Primer must be used on TPO single-ply roof substrates.

When installed properly, the ChemCurb System forms a durable waterproof rubber seal around penetrations of any size. An extended manufacture warranty against leaks is activated when ChemLink receives a completed warranty card and proof of purchase.

  1. Bonding surfaces should be clean, dry and free from all contamination that may inhibit the sealant’s performance.

  2. Remove all previously applied caulk, mastic, cement, asphalt, and other contaminants from penetrations with a wire brush.

  3. Brush away all gravel or loose granules. Isopropyl alcohol is an effective cleaner for surface preparation.
