Most of the time when I’m talking with architects on new projects or property managers on reroof jobs, the conversation is about the best roof surface for the particular job. While that is important, I want to suggest that almost as important is the flashing that is done to finish the job off. Here’s why. All buildings settle. Over time that settling will be more in some parts than in others. This will cause cracking in the buildings foundation, which affects the roof envelope. Any interruption in the roof field that is not properly flashed may open the building up to leaks. To protect our customer’s roofing investment, we properly install flashings in each of these critical areas:
- Wall parapets and other vertical surfaces
- Edge details and gravel stops
- Expansion and control joints
- Roof penetrations. That is, connections for vents, skylights, roof drains, and equipment
- Water conductors: built in gutters, alleys, and scuppers.
