Secure it first, then repair it properly
The first job after a storm is stopping more damage. A torn roof or broken window lets in rain for every day it stays open, and that water damage often costs more than the original hole. We tarp, board up and remove debris from the structure first.
Then we assess the full damage: roof, flashing, gutters, siding, windows, and inside the walls and ceilings where water may have travelled. GTA winters add ice damming, where ice at the roof edge pushes meltwater under the shingles and into the house.
