When a roof in Thorpe St Andrew has reached the point where repairs are no longer keeping up, a full replacement is often the most practical and cost-effective path forward.

A roof replacement is not simply a case of laying new tiles over the old ones. The correct approach is to strip everything back to the timber structure, inspect every rafter and batten for rot or damage, replace whatever needs replacing, and then build the new roof up from scratch with modern underlay, fresh battens and your chosen covering material.
Skipping the strip-back is a false economy. Hidden problems in the deck or timbers, left unaddressed, will shorten the life of an otherwise new roof. Any roofer quoting for a full replacement should be including a proper strip and inspection as standard.
At Poringland Roofers we carry out complete roof replacements on all property types, stripping back to the timbers and starting fresh. We cover Thorpe St Andrew and the wider area around Poringland.
The material you choose affects how the finished roof looks, how long it lasts and what it costs. Here are the main options for pitched roofs in this part of Norfolk:
When comparing quotes, make sure each one specifies the same material and grade. A quote using budget artificial slates will look very different from one using Welsh slate, even if the labour content is identical.
Prices vary with roof size, pitch, access, the material chosen and what the timbers reveal once stripped. As a working guide, a full replacement on a standard semi-detached property typically costs more than a simple repair, and larger detached houses or those needing significant timber repairs cost more again. A roof replacement using natural slate will cost more than the same roof in concrete tile.
Any quote well below typical replacement costs is worth questioning closely - it usually means corners are being cut somewhere, whether on underlay specification, batten depth, or the strip-and-inspect stage.
VAT applies to most roofing work. If a contractor quotes a suspiciously round number that happens to exclude VAT, ask the question before you agree.
This is the part that trips up many homeowners, because roof replacement is not a purchase most people make more than once or twice in a lifetime. The contractor market is mixed. Some firms do excellent work; others cut corners in ways that are invisible until the problems appear years later. Here is what to ask, and why each question matters.
Some roofers offer to overlay a new roof over the existing covering. This keeps costs down in the short term but prevents a proper inspection of the structure underneath. Ask specifically whether the existing covering will be fully stripped, whether the battens will be replaced, and whether the felt or underlay will be renewed. The answer should be yes to all three for a genuine replacement.
Modern breathable membrane underlay has largely replaced traditional sand-and-felt in new roofing work, and for good reason. Breathable underlay allows moisture vapour to escape the roof space rather than condensing on a non-porous felt layer. Ask the contractor to specify what product they intend to use and, if it is a branded product, you can look it up independently. This is a detail that is rarely explained in a quote unless you ask for it.
This question reveals a great deal about how a contractor works. Rotten or damaged rafters and ridge timbers are common findings once a roof is stripped, particularly on older properties. A good contractor will have a clear process: they stop, show you the problem, give you a revised cost for the timber repair before proceeding, and do not continue until you have agreed to the additional work. Be wary of contractors who give you a vague answer, or who say they will just include it at no extra charge - that usually means they are cutting the timber work short rather than replacing what genuinely needs replacing.
For a job of this size you should get at least two or three written quotes. When comparing them, check that each quote covers the same scope - strip and dispose of old materials, replace battens, new underlay, supply and fix new tiles or slates, make good the ridge, flashings and any lead or valleys. A quote that omits flashings, for example, is not a like-for-like comparison with one that includes them.
The cheapest quote is not automatically the wrong choice, but if it is significantly cheaper than others you have received, ask the contractor to walk you through how they have priced each element. Roofers who price low and then add extras at the end are one of the most common complaints in the trade.
A full roof replacement takes more than one day. Ask how the contractor will protect your property at the end of each working day and in the event of unexpected bad weather. The answer should involve temporary sheet covering secured across the open section of roof. If a contractor cannot give you a clear answer on this, it is a warning sign.
A full roof replacement requires proper scaffolding - not ladders with a board across the top. Full perimeter scaffold is the standard for a replacement job because it protects both the workers and the property, and it allows materials to be staged on a working platform rather than repeatedly lifted by hand. If a quote does not include scaffold costs, check whether scaffold is being hired separately or whether it is simply absent from the plan.
Stripping a roof generates a significant volume of waste - old tiles, broken slate, felt and timber offcuts. Ask whether skip hire is included in the quote or charged separately, and confirm that the contractor is disposing of waste lawfully. The liability for waste from your property can fall back on the homeowner if it is not handled correctly.
A contractor who has recently completed a full replacement on a similar property type locally should be able to point you to previous customers willing to speak to their experience. Online reviews are useful but can be selective. A direct conversation with a previous customer - even a brief one - is more reliable than a curated testimonial.
Beyond the questions above, there are a few patterns that should give you pause:
A written quote for a roof replacement should include: the full address and a description of the scope of work, the materials to be used (tile or slate type and grade, underlay product, batten size), whether scaffold is included and for how long, how waste removal is handled, the total price including VAT, and an estimated start date and duration. If you receive a quote that is vague on any of these points, ask for clarification in writing before you agree to anything.
You do not need to be a roofer to ask these questions. Any competent contractor will be pleased to answer them. The ones who are evasive or impatient when challenged on specifics are telling you something important about how they will handle problems once work is underway.
Once you have agreed on a contractor and a start date, the sequence for a typical pitched roof replacement runs roughly as follows:
The duration depends on the size of the roof and what the timbers reveal. A standard semi-detached property might take three to five days for the roofing element, with scaffold up before and taken down after. Keep that window in mind when planning around the work.
Not every roof problem needs a full replacement. If isolated slipped tiles, a damaged ridge section or a failed flashing are the issue, targeted repairs may well be the right call. A replacement becomes the more sensible option when a significant proportion of tiles are porous, broken or slipping; when the underlay has failed across the whole roof and rainwater is getting through in multiple places; when the timber structure has widespread rot; or when you have been patching the same roof repeatedly without lasting results.
A straightforward test: if a surveyor or experienced roofer looks at your roof and cannot point to a single cause of the problem, but instead finds widespread deterioration, the roof as a whole has likely reached end of life.
If your roof is showing signs of deterioration - staining on ceilings, tiles that have slipped or broken repeatedly, or a roof that has not been looked at in many years - call Poringland Roofers and book a roof survey. We will give you an honest assessment of what the roof needs, a clear written quote covering all the scope described above, and the answers to any of the questions raised on this page.
