Roof Deck Weatherproofing
Sealants, flashings, protective coatings
Beyond the Membrane
A roof deck membrane is only as good as its weakest point—and those weak points are everywhere: ledger connections, post penetrations, door thresholds, parapet transitions, and drain assemblies. In Chicago, where freeze-thaw cycles can occur dozens of times per winter, a single unsealed penetration or improperly flashed wall connection will eventually leak.
Our weatherproofing approach treats every vulnerability point with the appropriate material: elastomeric sealants that remain flexible through temperature extremes, pre-formed flashing boots for penetrations, through-wall flashings with proper end dams, and protective coatings that block UV degradation of exposed membranes. We install drip edges, counterflashing, and termination bars using manufacturer-specified details rather than field-expedient shortcuts.
Complete weatherproofing means your roof deck functions as an integrated system rather than a collection of separate components. Every joint, every seam, every transition is detailed to shed water and maintain its seal through Chicago's demanding four-season climate—protecting both your deck investment and the living spaces below.
