Fitting roof window flashing.

Start by fitting the sill flashing at the bottom of the frame. Read the instruction manual and check all the fixings and fittings are included as listed in the manual. Roof flashing is a thin material usually galvanized steel that professional roofers use to direct water away from critical areas of the roof wherever the roof plane meets a vertical surface like a wall or a dormer. When fitting flashings to flat roofs no overlap onto the roof is required as the roof itself will have it s own upstand flashing built into it.

Finally fit the flashing above the frame. Once the roof window is unpacked only carry it by lifting it from the underside of the baseplate and store flat on the floor. Moving up on to the roof fit the flashing around the frame according to the manufacturer s instructions. Secure the flashing as instructed with nails or roof cement.

Flashing is installed to surround roof features such as vents chimneys and skylights.
