Manufacturer Profile
Why we specify Henry
Henry Company is a building science company, not just a roofing manufacturer. Henry's product portfolio spans roofing coatings, air barriers, vapor retarders, and waterproofing membranes — making Henry the preferred specification for projects where roof restoration must integrate with a broader building envelope upgrade. Henry's silicone coating systems carry ENERGY STAR ratings and are available through broad national distribution, providing no lead-time premium in any market.
Henry's commercial roofing certification program verifies installer training, application technique, and quality assurance protocols. As a certified Henry applicator, we install and warranty the full Henry commercial coating lineup and can coordinate Henry silicone roof restoration with Henry Air-Bloc air barrier specifications on the same project — a unique capability for building owners pursuing comprehensive building envelope performance improvements.

Honest Comparison
When to specify Henry vs. alternatives
Henry is the preferred specification when the project scope extends beyond the roof membrane to include air barriers, vapor retarders, or below-grade waterproofing. Henry's distribution strength means material availability in any market on short notice — useful for emergency repairs and fast-track projects. On straight roof-only restorations, Gaco S20 typically carries a longer track record for ponding water applications.
Common questions
about Henry.
Technical questions we field before every assessment on this system.
01What makes Henry different from Gaco or Mule-Hide for commercial roof restoration?
Henry integrates roof coatings with air barriers and waterproofing under one specification — ideal when the project extends beyond the roof.
02Is Henry HEN-SIL 241 rated for ponding water like Gaco S20?
Yes. HEN-SIL 241 is a 100% silicone system rated for ponding water with NDL warranty language that explicitly includes standing water coverage — equivalent terms to Gaco S20 and Conklin Equinox.
03Can Henry silicone roof coating and Henry Air-Bloc be specified on the same project?
Yes — and this is Henry's unique advantage. We can specify and install both systems and document them under a single Henry building envelope warranty, simplifying the owner's warranty management.
04How does Henry's distribution network compare to other manufacturers?
Henry has the broadest North American distribution of any commercial roofing coating manufacturer — available through major roofing distributors in every market. No lead-time premium on materials, which is critical for emergency repair situations.
05Does Henry silicone qualify for ENERGY STAR cool roof credits?
Yes. Henry HEN-SIL 241 white formula meets ENERGY STAR initial and aged reflectivity requirements. We provide full documentation for utility rebate programs, LEED submissions, and corporate sustainability reporting.
