Upstand, joint, seam and protrusion weatherproofing
Upstands, seams, joints, and roof protrusions concentrate movement and standing water, so they are the first details to leak on an otherwise sound roof.
The need for upstand, joint, seam and protrusion weatherproofing
BHI Coatings performs upstand, joint, seam and protrusion weatherproofing across Alvin and the Texas Gulf Coast. Movement and standing water both collect at upstands, seams, joints, and roof protrusions. That is why those details leak first, even when the rest of the roof is perfectly sound. A single open upstand or pipe boot is enough to put water into the deck while the field membrane is still doing its job.
How BHI Coatings does upstand, joint, seam and protrusion weatherproofing
Our crew preps each detail, then works a cold-applied membrane into the upstand, seam, joint, and protrusion by hand. Embedded fabric reinforces the complex geometry so the membrane bridges movement at the hardest points. The work is done in place with no hot work, using a Belzona 3000-series membrane to seal around pipes, curbs, and parapets.
The details that leak first get sealed, and the sound field of the roof is never touched. You stop chasing water at every penetration and edge.

Roof cracks and high-movement detail areas keep working open under thermal cycling, splitting rigid coatings and reopening leak paths.
