Roof replacement means stripping the existing covering back to the deck (or in some cases the rafters) and fitting a new roof system: felt or membrane, battens, tiles or slates, ridge and hip finishes, flashings, and ventilation. It's a bigger job than a repair or a re-roof patch, and it's usually called for when a roof is past 20-30 years old, has widespread slipped or cracked tiles, persistent leaks in multiple spots, or sagging that points to deck or timber problems underneath. We've listed 9 roof replacement and installation contractors covering Norwich, ranging from small local crews to larger installation teams.
What to look for before you hire
A proper quote should follow a physical inspection, not a drive-by guess, and it should spell out the materials (tile or slate type, felt or membrane grade, batten spec), scaffolding costs, skip or waste disposal, and expected timescale including weather contingency. Ask whether the contractor is insured, whether they offer a guarantee on workmanship separate from the manufacturer's material warranty, and who's actually doing the work: subcontractors or the firm's own team. For anything requiring building control sign-off, check they can provide it or work under a competent person scheme.
How our scoring works
We score each contractor on things that matter to homeowners: how they communicate before and during the job, whether pricing matches what was actually delivered, the standard of finish on flashings and ridges, and how they handle problems that crop up once the old roof comes off. You can see the full ranked list and reasoning in our best roofing contractors in Norwich guide, and the criteria behind it are explained on our methodology page.
