A complete commercial service
Water can travel before you see it.
On a commercial roof, water may move across insulation, deck flutes, structural members, vapour-control layers or service penetrations before appearing inside. A useful investigation connects interior evidence with the roof assembly and the conditions that trigger the leak.
Weather pattern
Wind direction, rain duration, freeze-thaw and ponding can change where water enters.
Assembly movement
Membranes, flashings, curbs and metal details move differently through temperature cycles.
