How we work in Chestermere
Why Vent And Edge Selection Matters More Here
Standard box vents and cheap ridge vent products can take water in wind-driven rain, and on an exposed Chestermere roof that shows up as attic moisture and stained ceilings that get blamed on the shingles. We choose vent types and locations for a high-wind lot, and we check the ones already up there during the inspection.
Edge metal is the other one. Drip edge and rake metal in a light gauge will oscillate in Chestermere wind until the fasteners loosen, and then the wind gets under the starter course. Heavier gauge and a tighter fastener spacing costs very little and prevents the failure that peels a roof.
