A full roof replacement means stripping everything back to the bare timbers, checking the structure underneath, then building the roof up again from scratch. That includes the battens, felt underlay, tiles or slates, ridge, hips if the roof has them, verges, flashings and any lead work around chimneys or skylights. Each layer matters. A beautiful top course of slates on a failing underlay will still leak within a few years.
The materials chosen affect both the look and the lifespan of the finished roof. Natural Welsh or Spanish slate is widely regarded as the most durable option, with a lifespan measured in generations. Concrete interlocking tiles are heavier but cost less upfront and suit a wide range of roof pitches. Traditional plain clay tiles give a warm, classic look and are well suited to pitches of 35 degrees or more. Each material has its own weight loading, so your installer should check the existing timber structure can take what you are proposing before any order goes in.
A new roof in the UK typically costs between £5,000 and £15,000 for a standard semi-detached or detached house, depending on size, pitch, access and the materials specified. Larger or more complex roofs - those with multiple valleys, dormers or a large chimney stack - sit toward the top of that range or beyond it. Always get a breakdown of materials and labour separately so you can compare quotes properly.
For a job of this size, the process of choosing who does the work matters as much as the work itself. Ask each roofer to walk you through their quote line by line. A good quote lists the exact materials being used, the brand or type of tile, the underlay specification, how waste and scaffold are handled, and what happens if the timbers underneath turn out to need repair. Vague quotes that lump everything into a single price are a warning sign.
Ask to see examples of completed new roofs, and where possible speak to those customers directly. Check whether the roofer is willing to put a start date and an expected completion window in writing. Avoid paying large deposits before work begins; a reasonable materials deposit on a large job is understandable, but handing over more than 20 to 25 per cent before a single tile is lifted puts you in a weak position if things go wrong.
For homeowners in Horsford and the surrounding villages of mid-Norfolk, word of mouth is often the most reliable filter. If a roofer has done good work nearby, neighbours will usually say so. If there have been problems, you will likely hear about that too.
Between booking your roofer and the work starting, there are practical steps worth taking that most homeowners overlook. Getting these right means the job runs more smoothly and you are better protected if something unexpected comes up.
Read your current policy before work starts. Some insurers require you to notify them when major structural work is taking place. Failing to do so in the event of an incident during or after the work could affect a claim. Check whether the policy covers damage caused by third parties working on your property, or whether you need to confirm the contractor carries their own cover. Do not assume - read the small print or call your insurer directly.
Access to the loft space is often needed during a re-roof, and loose items stored there can be damaged by vibration, falling debris or dust. Move anything valuable or fragile out before work starts. If you have insulation boards or loose fill insulation in the loft, tell the roofer in advance - some types of insulation can interfere with the underlay installation if the roof is being stripped and re-felted.
Scaffold goes up before tiles come off, but the area directly around your house will still be active and potentially hazardous throughout the job. Move garden furniture, pots, children's play equipment and any vehicles away from the building before work starts. Falling debris is an unavoidable part of stripping a roof, and even with good housekeeping on site, smaller pieces of old tile or mortar can travel further than expected.
If you have noticed specific problem areas - a particular corner that leaks in heavy rain, a section of ridge that has been repaired before, a chimney flashing that has been pointed repeatedly - tell the roofer before they start rather than waiting to be asked. This information helps them look more carefully at those areas when the roof is stripped back, and it may affect what they find underneath.
A re-roof is one of the best opportunities to improve or replace loft insulation, because the space is already being disturbed. If your current insulation is thin, old or damaged, having it topped up or replaced at the same time as the roof work is far more cost-effective than doing it as a separate project later. Current building regulations recommend a minimum of 270mm of mineral wool insulation between and over the joists in a cold loft. Ask your roofer whether they can include this in the job, or arrange a separate contractor to follow on immediately after the roof is complete.
Before work starts, confirm what time the team will arrive and finish each day, how rubbish and old tiles will be removed (skip, bag or loose load), and whether the scaffold will be sheeted at the end of each day if the roof is open to the weather. These details matter most on exposed roofs where a sudden downpour could cause internal damage if the house is left open overnight. Get the answers in writing, even if it is just a brief confirmation by email or text.
Scaffold goes up on the pavement or against a shared boundary, and the noise of stripping and battening is significant. Letting neighbours know in advance is both courteous and practical. If the scaffold needs to cross a shared access or boundary, you may need their written agreement. Check this early to avoid a last-minute delay on the day work is due to start.
The internet makes a great many roofing tasks look manageable. Some are genuinely within the reach of a competent DIYer. Most are not, and the consequences of getting it wrong on a new roof are serious and expensive.
Stripping tiles sounds straightforward but carries real risk. Old tiles, particularly clay or natural slate, can be brittle and unpredictable when disturbed. The timber structure underneath may be in worse condition than expected, and removing weight from one part of the roof unevenly can put stress on weakened rafters or purlins. Working at height without proper scaffolding and edge protection is how serious accidents happen. Scaffold hire is a significant cost, but it is built into every professional quote for good reason.
The underlay and batten system is what determines whether your new tiles will perform as they should. Batten spacing has to be calculated precisely to the tile manufacturer's specification for the pitch of your roof. An error of a few millimetres across the full length of a roof results in tiles that do not seat properly, gaps that allow wind-driven rain to penetrate, and a roof that looks wrong from the street. The underlay needs to be lapped correctly at every join and at every penetration, and drape tolerances matter for drainage. This is skilled work, not labouring.
Bedding the ridge tiles in mortar looks like a simple job, but the mortar specification, the depth of bed and the way each tile is positioned affects how long the ridge holds together. Poorly bedded ridges are one of the most common sources of storm damage because once the mortar cracks, individual ridge tiles become loose and can be lifted by wind. On a brand-new roof, getting the ridge right is especially important because it sets the standard for everything below it.
Lead work around chimneys, skylights, soil pipes and valleys is specialist work. Lead has to be cut, dressed and fixed in a way that allows for thermal movement, and the step and cover flashing system used against a chimney breast has to be correctly built into the masonry to work reliably. Improperly installed lead is a common source of leaks that are difficult to diagnose because water can travel a considerable distance from where it enters before it appears on a ceiling. If a new roof is being installed, all the lead work should be done by the roofer as part of the same job.
Some homeowners take the opportunity of a new roof to remove a redundant chimney stack at the same time. This is sometimes a sensible decision but it is a structural job that affects the roof structure, the party wall if you are in a semi-detached property, and potentially your planning obligations. Get a clear written scope from the roofer for what the chimney removal involves and confirm whether a structural engineer is needed before any decisions are made.
The choice of tile or slate affects the weight loading on your timbers, the batten spacing, the finished appearance and the long-term maintenance needs. Here is a plain summary of the main options.
If your neighbours have a particular tile type and you want the roof to blend in, check what they have before specifying. Matching an existing tile profile is often possible but not always straightforward, and some older clay tile profiles are no longer in production.
When a roof is stripped, you are left with a significant volume of old tile or slate. What happens to it matters both practically and financially. Some old natural slates are worth recovering and reselling if they are in good condition; your roofer should tell you if this is the case before they are removed, not after. Old concrete tiles generally have no reclaim value and go to a licensed disposal point. Confirm in advance whether the disposal of old materials is included in the quote, and what the method will be - a skip on the drive, a builders bag or direct loading to a vehicle.
Every full re-roof requires scaffolding. A firm that suggests otherwise is either proposing to do the job from ladders - which is unsafe and unacceptable for a full strip - or is using a hop-up or tower system that is not adequate for the full perimeter of a house. Scaffold is typically erected a day or two before work starts and dismantled after the roof is complete and inspected. The hire period is usually included in the quote. Ask whether the scaffold includes a sheeted platform at eaves level for debris containment, and whether handrails are provided at all open edges. This matters both for safety and for protecting your garden and paths below.
Three quotes is the standard advice for any significant building job, and a new roof qualifies. But three quotes only help if you are comparing like for like. Ask each roofer to specify the exact tile or slate they are quoting, the underlay type (a breathable membrane is now standard), the batten size, what they are doing at the ridge and verge, and how they are handling any existing lead work. A quote that does not specify any of this cannot be meaningfully compared against one that does.
Price differences of 20 to 30 per cent between quotes on the same materials and specification are worth investigating. The gap may be explained by different overhead structures, but it may also indicate that something has been left out. Ask directly: "What is not included in this price that another roofer might include?" A straightforward answer to that question tells you a good deal about who you are dealing with.
