In plain terms
A roof window that stays dry
A Velux window stays dry because of the flashing kit, not because of sealant around the frame. The kit has to match the covering: slate, tile or pantile. The underlay has to dress into the window. If it runs underneath, water goes into the loft.
We check the rafters and the opening before we order, then supply the window and fit it. If the ceiling is opened, we make the lining good. Scaffold is usually needed, and it is included in the quote rather than added on the day.
We do this from Hessle, across Hull, Beverley, Anlaby and Anlaby Common, Willerby, Woodmansey and the villages in between. Call 01482 627895 or use the form further down. We look at the roof before we price it. A written quote is available if you want one, and the work we agree is guaranteed for at least 12 months, and often for longer depending on the job.
