A leaking roof or a cluster of slipped tiles puts most homeowners under pressure. The natural instinct is to get someone up there quickly and get it fixed. That urgency is understandable, but rushing to agree to work without asking the right questions is one of the most common reasons roof repairs go wrong, cost more than they should, or fail within a year or two.
This page covers everything you need to know about roof repairs - what the most frequent problems are, what a proper repair involves, what it typically costs - and then goes into detail on the one thing most homeowners skip: how to assess a contractor before you hand over any money.
Roof problems in most homes fall into a handful of categories. Knowing which one you are dealing with helps you have a more informed conversation with anyone you bring in to look at the job.
Individual tiles or slates can slip out of position over time as the nibs that hook them onto the batten wear or the fixing nails corrode. Cracked tiles are common after heavy frost, when water that has seeped into a small crack expands and splits the tile. Missing tiles leave the felt underlay exposed, and felt is only ever a secondary line of defence - it degrades quickly once it takes prolonged weather.
A good repair here means sourcing a matching tile or slate, checking the batten is sound before refixing, and inspecting the surrounding tiles for similar movement. Simply nailing one tile back without checking its neighbours is a short-term fix.
Flat roofs on extensions, garages and bay windows take a great deal of weather and tend to fail sooner than pitched roofs. The most common systems are traditional built-up felt and EPDM rubber. Each fails in its own way.
Felt roofs have layers: a base layer, intermediate layers and a cap sheet, bonded together with bitumen. Over time, UV exposure makes the cap sheet brittle. Thermal movement - the roof expanding and contracting with temperature changes - causes the felt to crack, split at the seams, or pull away at the edges and upstands. Blisters form when trapped moisture vapour pushes up beneath a layer. None of this is unusual; it is simply how built-up felt ages.
A split in the cap sheet lets water straight through. If the split is isolated and the surrounding felt is still in reasonable condition, a section repair using torch-on felt or a compatible reinforcing membrane can work well. The repaired area needs to overlap the existing felt by at least 150mm on all sides and bond securely. A repair that simply patches over a crack without proper adhesion will lift within months.
Blisters are often misunderstood. Not every blister is actively leaking - many are dry air pockets. The question is whether the blister has cracked open and admitted water. A roofer should open a blister, check whether the layer beneath is damp or sound, and then cut back the damaged section cleanly before bonding new felt in. Painting over a blister achieves nothing.
Where sheets of felt overlap, the bond can fail as the bitumen ages. Water then tracks along the lap and finds its way through. Lap failures are often the hidden cause of a leak that appears to be coming from somewhere else entirely. A thorough inspection looks at every lap and seam, not just the obvious damage.
At the edges of a flat roof, the felt turns up against a wall (the upstand) or turns down over the fascia. These edges are vulnerable because they are the thinnest sections and get pulled by wind. A loose upstand that is not refixed quickly lets water run behind it and down into the wall or ceiling void. Refixing and sealing the edge is straightforward if caught early; by the time water has been tracking down a wall for months, the repair bill is larger.
Lead flashing is used wherever a roof meets a wall - chimney sides, parapet walls, abutments. Lead is durable but it does move with temperature. Over decades the lead can crack, the mortar that holds it into the wall joint can fall out (called the raggle or chase), or the lap between sections opens up. Water running down a wall or appearing inside around a chimney breast often traces back to flashing rather than the tiles themselves.
Repointing the raggle joint and re-dressing the lead is usually sufficient on older flashing. If the lead has cracked through, a patch repair using compatible lead welded or bonded over the crack can extend the life significantly. Full replacement is needed when the lead has thinned too much to hold.
Any penetration through a roof - a rooflight, a soil pipe, a flue, a vent - is a potential weak point. The seals and flashings around these deteriorate independently of the roof covering. A leak appearing near a rooflight is not always a rooflight problem; it may be the flashing collar. A roofer who opens up the rooflight frame to investigate rather than just re-sealing around the outside is doing the job properly.
A flat roof is never truly flat - it should have a fall of at least 1 in 80, and ideally 1 in 40, towards the outlet. If water is ponding after rain, the fall has failed or the outlet is blocked. Ponding water accelerates felt degradation significantly and adds structural load. Clearing the outlet is the first step. If the fall has failed because the deck boards beneath have deflected, that is a more involved repair that may require lifting sections of felt to reinstate the timber beneath.
Standing water on a felt roof is a problem that should not be left, even if there is no active leak yet. A roof that holds water for 48 hours after rain needs a roofer to assess the drainage and fall.
A repair is genuinely the right answer when the damage is localised and the rest of the roof covering is in reasonable condition. On a pitched roof, replacing a handful of slates and resealing a flashing makes complete sense if the remaining slates are sound. On a flat felt roof, localised repairs are worth doing if the felt is fewer than 15 to 20 years old and the majority of the surface is intact.
When felt is beyond about 20 to 25 years old, brittle across most of its surface, with multiple lap failures and widespread cracking, a full re-felt will almost always cost less in the medium term than repeated patch repairs. A roofer who tells you a 25-year-old roof needs a full replacement rather than just patching one section is, in that situation, giving you more useful advice.
The answer to "repair or replace?" should always come after a proper inspection of the whole roof surface - not after a glance from the ladder at the one obvious problem.
Replacing a few slipped or broken tiles on a pitched roof typically costs in the region of £150 to £400 depending on access, tile type and how many need doing. Re-bedding ridge tiles commonly runs from £200 to £500 for a typical semi-detached or terraced run. Chimney flashing repairs generally fall between £200 and £600.
On flat roofs, a localised felt patch repair is typically £200 to £500. A more extensive section repair covering a significant area of a garage or extension roof can reach £800 to £1,500. Full re-felting of a single garage roof in the UK currently ranges from around £800 to £1,800 depending on size, deck condition and felt specification. EPDM rubber system installations tend to cost more than felt but last longer without repair.
These are honest typical ranges based on current UK labour and material costs. Any quote should set out clearly what is included - materials, disposal of old felt, repair or replacement of any rotten deck boards - so you can compare fairly.
Some repairs can, some cannot. Temporary emergency measures - tarping a roof, sealing an open crack to stop active water ingress - can be done in the rain. Torch-on felt work and most adhesive-bonded repairs need a dry surface to achieve a proper bond; doing them in wet conditions produces a repair that will fail quickly. An honest roofer will carry out emergency make-safe work in the wet but return to complete the permanent repair in dry conditions rather than rush through it.
It should, yes. If deck boards are soft, delaminating or visibly rotten when the old felt is lifted, they need replacing before new felt goes down. Laying new felt over rotten timber produces a surface that will move, crack the new felt, and fail quickly. Any quotation for felt roof work should specify how rotten decking will be handled and whether replacement boards are included in the price or charged as an extra if found.
This is the part most homeowners skip, and it is the section that matters most. Getting a roof repaired is not like buying a product with a known specification. The quality of the finished job depends almost entirely on the competence and honesty of the person doing it. Here is how to assess that before you commit.
A quote that says "roof repairs - £450" tells you almost nothing. You need to know what materials are being used, how many tiles or how much felt is being replaced, whether scaffold or a tower will be used or just a ladder, and whether disposal of old materials is included. A detailed written breakdown lets you compare quotes properly and also protects you if there is a dispute later about what was agreed.
If a contractor cannot or will not provide a written breakdown, that is itself useful information.
A roofer who has properly inspected your roof should be able to explain, in plain terms, what they found, where the problem is originating, and why the repair they are proposing will solve it. If the explanation is vague - "there are a few issues up there, we'll sort it" - that should give you pause.
Ask specifically: where is the water getting in? Is the problem isolated or is there wider deterioration? Will this repair solve the problem, or is it a temporary measure? A contractor who gives clear, direct answers to these questions is worth more than one who just gives you a low number.
Drone photographs, photos taken from the roof, or a report with images are standard practice among experienced roofers and genuinely useful to you. They show you what was found before work began, confirm the repair has been carried out, and give you a record for your own files. Ask before the job starts whether photographs are included.
This is an important question. On older roofs especially, a roofer who lifts felt or removes tiles may find rotten battens, failed underlay, or deck boards in worse condition than expected. You need to know in advance: will they stop and call you before doing additional work? Or will they proceed and present a larger bill at the end? The professional approach is to stop, document what was found, explain it to you and get your agreement before going further.
Make this clear before work begins: "If you find anything beyond what you have quoted for, I want a call before you do any extra work."
The cheapest quote is not always the worst job, and the most expensive is not always the best. But a quote that is substantially lower than the others - say 40% or more below - deserves scrutiny. Ask what is different about it. Are they using lighter-gauge lead? A thinner felt specification? Skipping scaffold where others have included it? Sometimes the answer is reasonable. Sometimes the price is low because corners are being cut.
A roofer who works in and around Wimblington, March, Doddington and the neighbouring villages will have a reputation to maintain locally. They are also reachable if something needs attention after the job is done. A company based far away with no local presence and a call centre number is harder to get back once payment is made. Ask for a local address, not just a mobile number.
Manufacturers of roofing materials - felt systems, EPDM membranes, lead - often provide their own product warranties. These are separate from anything a contractor offers on their workmanship, and they are worth asking about. A quality torch-on felt cap sheet, for example, carries a manufacturer's expected service life that a roofer can tell you about. This is factual product information, not a promise made by the contractor, and it helps you understand what you are paying for.
None of these red flags on their own mean a contractor is dishonest, but a combination of them should make you look elsewhere.
A competent roofer will arrive with the right equipment to access the roof safely - scaffold tower, crawl boards, or at minimum a proper ladder secured at the top. They will inspect not just the obvious damage but the surrounding area: the condition of nearby tiles or felt, the flashings, the gutters and fascias. They will explain what they found in plain language and provide a written quote before any work begins.
On a flat roof job, they should lift enough of the existing covering to check the deck condition before confirming the price. On a pitched roof, they should walk the ridge line if access allows and check for mortar failure at the ridge and hips, not just the one slipped tile that prompted the call.
After the work is done, a good roofer will clear up properly, remove old materials from the site and be willing to show you photographs of the completed repair.
Most roof repairs are straightforward when caught early and done properly. The problems arise when a repair is rushed, underspecified or carried out by someone who will not be easy to contact afterwards. Taking a few extra days to ask the right questions, get a written breakdown, and satisfy yourself that the contractor has properly inspected the roof before quoting will nearly always produce a better outcome.
