This was a grp we did on a timber framed construction. The roof was decked in OSB boarding with an inlayed gully running around the outer perimeter. We also fitted a lead welded outlet point in the front corner. Trims were installed to the perimeter and around the rooflight before the bandaging of the joints was completed. The resin and fibreglass matting was then installed and allowed to hard cure before our 1st topcoat was added to the whole roof and box section. We then fitted our lead flashings, pointed in place and installed a further layer of dark grey activated topcoat.
