A roof replacement is not a patch or a repair. It means stripping everything back to the timber structure underneath, inspecting every rafter, purlin and ridge board, dealing with any rot or damage, and then rebuilding from the deck up with new felt, battens and tiles or slates. The finished job should perform as well on day one as it does ten years later.
That process takes longer and costs more than a repair, but it is the right call when the roof is too far gone to fix in sections. A patchwork approach on an old roof can cost more over five years than a single replacement carried out properly from the start.
We cover Little Shelford and neighbouring villages including Girton, Histon, Fulbourn, Trumpington, Milton, Waterbeach, Impington and Cherry Hinton, as well as Cambridge itself. Whether your property has a pitched roof with concrete or clay tiles, or a flat roof section over a bay window or extension, the process of choosing a contractor matters just as much as the materials.
Most homeowners know something is wrong before they call anyone. The question is whether the roof can be extended with targeted repairs or whether replacement is the only sensible route. A common problem is reaching a point where new tiles are being bedded onto failing mortar, rotten battens or saturated felt, so the repair work is wasted within a year or two.
None of these on their own always means a full replacement is needed, but two or three together usually do. A roofer should be able to tell you plainly which category you are in and why.
The choice of material affects both the cost and how long the finished roof performs. For pitched roofs, the main options are concrete interlocking tiles, natural slate, and plain clay tiles. Each has a different weight, profile and expected lifespan.
Concrete interlocking tiles are the most common choice on post-war properties. They are durable, widely available and cost-effective, with manufacturers typically quoting lifespans of forty to sixty years for good-quality tiles. They are heavier than slate, so the supporting structure needs to be adequate.
Natural slate, whether Welsh, Spanish or Brazilian, gives a thinner, lower-profile finish and is the correct choice for many older properties where matching the original appearance matters. Good natural slate can outlast the building it is on, though the bedding mortar and flashings will still need attention over time.
Plain clay tiles are common on period properties and in conservation-sensitive areas. They are expensive but authentic, and sourcing matching tiles for older roofs can be a significant part of the job.
For flat roof sections, the two most practical systems for residential properties are torch-on felt (sometimes called modified bitumen) and EPDM rubber membrane. EPDM in particular has become more common on domestic extensions and garage roofs because it is a single-piece membrane with no joins to fail. Torch-on felt in two or three layers is a well-established system when laid correctly over suitable insulation. Both systems are very different from a thin mineral felt layer, which is the type that typically fails within a decade on a garage or porch roof.
Roof replacement costs vary with the size of the roof, the pitch, the material chosen, the complexity of the valleys, hips and ridges, and the condition of the timber underneath. As a broad guide, a straightforward pitched roof replacement on a semi-detached house using concrete interlocking tiles typically runs from around £5,000 to £9,000. Natural slate adds cost both in materials and in the additional fitting time, so the same roof in slate might run from £8,000 to £15,000 or more.
Flat roof replacements for domestic extensions and garages typically cost from £70 to £120 per square metre for a torch-on felt system, and from £80 to £130 per square metre for EPDM, depending on the existing structure and whether insulation is being upgraded at the same time.
These figures are representative of current UK pricing. Any quote you receive should break down materials, labour, waste disposal and scaffold separately so you can compare like for like.
A full roof replacement will always require scaffold. Any contractor offering to strip and relay a pitched roof from ladders alone is taking a risk with both safety and the quality of the work. Scaffold allows the team to work safely, transport materials efficiently and inspect every section of the roof without cutting corners.
On a standard semi-detached or terraced house, scaffold is usually up for two to three weeks to allow for the stripping, any timber repairs, the relaying and the finishing work to the ridges and flashings. Detached properties with complex roofs will take longer. Expect some disruption to access around the house during this period, and let your neighbours know in advance, particularly if the scaffold touches a shared boundary.
Roofing sits in a sector where poor practice is common enough to be worth taking seriously. A roof replacement is one of the larger single expenditures a homeowner makes, and the work is largely out of sight once it is done. Choosing the wrong contractor is expensive to put right. The advice below is practical and specific.
Getting two or three quotes is not just about price. It is your opportunity to assess how each contractor approaches the job, how they communicate, and whether their explanation of the work holds together. Here is what to ask, and what to listen for.
A roofer who inspects your roof properly should be able to describe what they found in specific terms: which battens are rotten, whether the felt has failed across the whole slope or just a section, whether the ridge tiles are cracked or just de-pointed. Vague language like "the whole roof is shot" without detail is a warning sign. So is a quote given without getting onto the roof at all.
The quote should state clearly whether the price includes replacing rotten rafters, battens and felt as standard, or whether timber repairs are extra. Some contractors quote low by assuming the timber is fine, then add costs once the roof is stripped. A good contractor will give you a clear explanation of what is included and what triggers additional charges.
Find out exactly which tiles, felt and battens they intend to use. There is a significant difference between a 25-year concrete tile and a 60-year tile from the same manufacturer. Breathable roofing membranes have largely replaced traditional bitumen felt as the underlay of choice because they manage condensation better, but not every contractor uses them as standard. Ask.
The ridge, hips and any flashings around chimneys, dormers or abutments are where most leaks start. Ask whether the ridge is being dry-fixed or mortar-bedded, and why. Dry-fix ridge systems, which use mechanical clips and ventilated sections rather than mortar, are now widely recommended because mortar ridges can crack and lift after a few years of frost. Ask what is happening to your chimney flashing, valley gutters and any lead work, and whether the price includes new lead or like-for-like replacement.
A full stripped roof generates a substantial amount of waste: old tiles, broken slates, rotten timber, felt. The contractor is legally responsible for disposing of this properly. Ask whether waste removal is included in the quote and how they dispose of it. A skip or a trade waste vehicle are both fine. Fly-tipping is a criminal offence, and the homeowner can be held responsible if waste from their property is found dumped illegally.
Roofs regularly throw up surprises once stripped: rotten wall plates, undersized rafters, previous botched repairs that created hidden water traps. Ask the contractor how they handle these situations. Do they stop work and call you? Do they photograph the problem and quote for the additional work before proceeding? A clear process here protects you from shock bills at the end.
A verbal quote is not enough for a job of this size. Ask for a written document that names the materials, confirms the scope of work, states what is excluded, and gives a fixed total or a clear explanation of what additional items cost. Compare this document between contractors, not just the headline figure.
Confirm that the price includes scaffold, who supplies it, and who is responsible for it while it is up. Some contractors subcontract the scaffold separately; others include it. Either is fine, but you should know what you are dealing with and who to call if the scaffold becomes a problem.
These are not absolute disqualifiers on their own, but each deserves a straight explanation from the contractor before you proceed.
A reasonable contractor will answer all of these questions without taking offence. The ones who do not are usually the ones you need to avoid.
Ask for references from recent local jobs, not just names and numbers, but addresses you could drive past if you wanted to see the finished work. Check reviews on independent platforms. Look at how long the business has operated, whether they have a fixed address and a phone number that is answered, and whether their website shows actual work rather than stock images.
Word of mouth from neighbours in Little Shelford, Trumpington, Fulbourn or nearby villages is still one of the most reliable ways to find a roofer who performs. If someone on your street had a replacement done recently and was happy with the result, that is worth more than a list of accreditations you cannot verify.
A roof replacement is the natural point at which to address the fascias, soffits and guttering as well. The scaffold is already up, and replacing these items while the roof is being done costs far less in labour than returning to do them separately. Fascia boards carry the bottom edge of the felt and support the gutters; if they are rotten or pulling away, the gutter cannot drain correctly and water sits against the wall.
uPVC fascia and soffit systems are the most practical replacement option on most properties: they do not rot, do not need painting and are available in a range of profiles to match the existing style. Aluminium is another option for properties where a different finish is wanted. Ask your roofer whether they include this work or can price it as part of the same visit, and check whether the gutters themselves need replacing or just re-aligning to fall correctly to the downpipe.
If your property has roof lights, Velux-type windows or dormers, a full replacement is the right time to check their condition and, if needed, replace the flashings or the units themselves. Roof window flashings are a common source of leaks and are straightforward to replace when the surrounding tiles are already off. Ignoring them and roofing around a failing window frame creates a leak path that can sit undetected for years.
Dormers, particularly flat-roofed dormers, often have their own felt or EPDM covering that deteriorates independently of the main pitched roof. Check their condition as part of the same survey and, if they are close to end of life, replace them at the same time.
A number of properties in this part of Cambridgeshire have flat-roofed garages or extensions that were built with a thin mineral felt covering. When that covering fails, the options are to re-cover with a modern torch-on felt or EPDM system, or in some cases to convert the flat structure to a low-pitch roof using a timber frame. A flat-to-pitch conversion costs more upfront but eliminates future flat roof maintenance and can add headroom or visual appeal, depending on the property.
If you are considering a conversion of this kind, it may require planning permission, particularly if the new structure raises the ridge height or alters the appearance of the building. Check with your local planning authority before proceeding.
If you are planning a loft conversion, replacing the roof at the same time can make practical sense: the structure is already being altered, and some of the labour overlaps. Conversely, if you are getting a straight replacement done and you know a loft conversion is on your five-year plan, tell the contractor now. The specification choices, particularly around insulation and ridge height, can affect what is practical later.
Gutters and downpipes are part of the roofing system. They exist to move water from the roof edge to a drain or soakaway. When they fail, water runs down the face of the building and into the wall or the foundation. Cast iron guttering on older properties looks good but is heavy, needs painting and can crack. uPVC is the modern standard. Larger-section "deep flow" or "square" gutters are worth considering on a large roof or on a slope that catches heavy rain, because standard half-round guttering can overflow in a heavy downpour.
When a new roof is fitted, check that the gutters are set to the correct fall, that all joints are sound and that the downpipes drain to a working outlet. A roof that sheds water perfectly onto a blocked or misaligned gutter will still cause damp problems.
A replacement done well should give you a roof that performs without attention for many years. The things that shorten that period are almost always related to poor specification of materials, inadequate ventilation in the roof space, or flashings and ridge work that were not done properly at the time.
Ask for the manufacturer's data sheets or product names for the tiles and underlay being used. Keep copies of the written quote, any change orders during the work, and the final completion paperwork. If the material manufacturer offers a product guarantee, ask for the documentation so you can register it if required.
If you are in Little Shelford and at the stage of getting quotes, ask each contractor for a survey and a written price before you commit.
