Why is roof flashing important?

Flashing is a key component in protecting against water damage.

Water can easily enter through vulnerable points in a roof such as windows, causing problems including mould and damp. Flashing isn’t just for windows either; it can be used in various places on a roof such as around chimneys or edges.

When installing a roof window or skylight, choosing appropriate roof window flashing is vital. It protects the vulnerable points of the roof to ensure the new installation doesn’t result in leaks.

Make buildings more durable and reduce indoor mould problems with our watertight flashing, suitable for a range of windows and roofs.

Foils and Collars

Our insulated foam collars reduce heat loss in homes, and our foil collars reduce installation times by eliminating the need for cutting. Create an airtight and insulated roof space with Dakea.
