Elevate Roof & Building Solutions on Instagram: "THIS IS WHY THE VALLEY FAILED 💧 Large volumes of water entered this property. The cause was traced back to the valley flashing. Valley laps measured around 15–20 mm. Minimum compliant laps are ~150 mm+, depending on roof pitch. When laps are undersized, capillary action and wind-driven rain allow water to track back under the valley iron. DIY repairs didn’t resolve the cause. The detailing itself is non-compliant. #roofinspections #roofrepair #bu
