Are you looking to improve the look of your roof? If you have an attic conversion that’s lacking in light, why not have a Velux skylight installed?
I will survey your roof and see if it is able to have a new skylight fitted before providing you with a quote.
For sloping roof installations, I remove tiles and take off the battens and felt (if fitted). Then your rafters are reconfigured to allow the fitting of the new Velux skylight, including flashings, as per manufacturers recommendations.
For flat roof installations, the felt is removed and the roof cleaned. Then a hole is cut to allow the fitting of your new Velux skylight. New felt is then prepared and readhered to your roof.
Finally I fit new tiles to enclose the skylight surrounds to ensure your roof is left in a water-tight condition.
