Flashing creates a weathertight seal and is essential to the durability of your window. The built-in guttering forms a mini-drainage system that allows rainwater to run around the window and off the roof. It’s essential to have the right window flashing to suit your roof window because it prevents water from entering the gaps between the adjoined building surfaces, which could lead to wood rot and structural damage.
