Roof replacement means stripping some or all of the existing roof covering down to the deck (or timber structure) and installing new underlay, battens, flashing, and covering, whether that's concrete or clay tiles, natural slate, or a felt/GRP flat roof system. It's a different job from a patch repair: it involves scaffolding, skip hire, building control sign-off in most cases, and usually a week or more of work depending on the size of the roof and the weather. Full installation also covers new-build roofs and large extensions where a roof is going on for the first time.
We list 7 roofing contractors serving Norwich in this category. Before you hire one, check they can show proof of public liability insurance, a manufacturer or trade body accreditation (NFRC, CompetentRoofer, or similar) that lets them self-certify work under Building Regulations, and a written quote that specifies materials, underlay type, ventilation detail, and how long the guarantee runs (on both materials and workmanship). Ask how they handle scaffolding and waste removal, and whether the quoted price is fixed or subject to change once the old covering comes off and the deck condition is known.
Our scoring weighs things like how consistently a contractor is reviewed for quality of finish, how they handle problems that come up mid-job, response times, and how clear their pricing and paperwork tend to be, rather than just an average star rating.
