Roofing advice & FAQs

A well-installed pitched roof using quality slate or clay tiles can last 60 to 100 years, though the underlying felt, battens and lead flashing will typically need attention before then - often after 20 to 40 years. Concrete tiles generally last 40 to 60 years before they begin to degrade, erode or lift. Flat roofs have shorter lifespans: a properly laid EPDM rubber roof can last 30 to 50 years, while a traditional three-layer felt flat roof may only last 10 to 20 years before it needs replacing. Regular maintenance - clearing gutters, checking flashing, replacing cracked or slipped tiles - extends the life of any roof significantly.

Key signs you may need a full replacement include widespread cracked, missing or slipping tiles across multiple areas of the roof, sagging or bowing to the roofline, daylight visible in the loft, or persistent damp patches on ceilings despite previous repairs. If the roof is over 50 years old and using its original materials, widespread deterioration is common and patching becomes uneconomical. A good roofer will carry out a thorough inspection and give you an honest assessment of whether targeted repairs will hold long-term or whether replacement is the more cost-effective route over the next decade.

Repair is usually the right choice if the damage is limited to one area, the tiles are otherwise sound and the roof structure is in good condition - a repair can add years of life at a fraction of replacement cost. Replacement makes more sense when a roof is ageing across its whole surface, when repairs are being done repeatedly in different spots, or when the underlying felt and batten system has failed. As a rough guide, if repair costs exceed 50% of a full replacement quote and the roof is near the end of its expected life, replacement is usually better value. An honest surveyor or roofer should be willing to explain their reasoning either way.

A full roof replacement on a typical three-bedroom semi-detached house in the UK costs roughly £5,000 to £12,000, depending on roof size, pitch, material chosen and access difficulty. Slate and clay tiles sit at the higher end of that range; concrete interlocking tiles are generally cheaper. Flat roof replacements are usually priced per square metre - EPDM rubber typically costs £80 to £120 per square metre installed. These are honest ballpark figures and costs vary considerably by region, specification and the condition of the underlying structure, so a proper site survey and written quote is the only reliable way to price your specific roof.

In most cases, replacing a roof using the same materials and keeping the same roofline is covered by permitted development rights, meaning no planning permission is required. However, if your property is in a conservation area - as parts of Ely are, given its historic city centre - or if it is a listed building, you may need conservation area consent or listed building consent before making changes, even like-for-like material replacements. Ely also has a number of older properties close to the Cathedral where additional restrictions may apply, so it is always worth checking with the local planning authority before starting work. Your roofer should flag this if they are familiar with working in the area.

There is no dedicated government grant solely for roof repairs, but some homeowners may qualify for help through the Great British Insulation Scheme or the Warm Homes: Local Grant, which can fund roofing work where it forms part of wider energy efficiency improvements. Eligibility typically depends on household income, benefit status and the property's energy rating. Some local councils also run discretionary repair assistance schemes, so it is worth contacting your local authority directly to ask what is available in your area. Always be cautious of cold-callers offering 'free roof replacement through government schemes' - legitimate grant programmes are applied for formally, not sold door to door.

A pitched roof has a slope that sheds water quickly and naturally, making it well-suited to the UK's regular rainfall, and it generally requires less maintenance over its lifetime. A flat roof - which actually has a very slight fall of around 1:80 to allow drainage - is common on extensions, garages and some modern homes, and can be the only practical option where head height or planning restrictions limit roof height. Neither is inherently better; the right choice depends on the building type and what is already in place. Modern flat roofing systems such as EPDM rubber perform far better than older felt, and a well-installed flat roof should not be considered inferior to a pitched one.

Chimney flashing - the lead or mortar seal between the chimney stack and the roof slope - is one of the most common sources of roof leaks in older UK properties. When lead flashing lifts, cracks or is poorly pointed, rainwater tracks down behind it and into the roof structure, often appearing as a damp patch on a bedroom ceiling or wall some distance from the actual entry point. Crumbling mortar pointing on the chimney stack itself can also allow water into the brick, leading to spalling and eventual structural problems. A chimney inspection every five to ten years, and prompt repointing or flashing replacement when needed, prevents much more expensive work later.

Gutters should be cleared of leaves, moss and debris at least once a year - ideally in late autumn after leaves have fallen - to prevent blockages that cause water to back up under the roof edge or pour down walls. Fascias and soffits, whether timber or uPVC, should be inspected at the same time for rot, cracks or gaps where birds and pests can enter the roofline. Timber fascias are particularly prone to rot where paintwork has failed, and once the wood is soft the gutter fixings lose their grip. Replacing timber roofline components with uPVC is a straightforward upgrade that removes the need for regular repainting and reduces long-term maintenance.

If water is actively entering your home, your first priority is to contain the damage - place bowls or towels under drips, move valuables clear. If the ceiling is bulging with trapped water, keep everyone out of the room and do not poke, prod or pierce it. Contact a roofer as soon as possible and explain the situation clearly so they can assess urgency; most roofers can carry out temporary weatherproofing - such as tarpaulin or emergency sealant - to stop active ingress until a proper repair can be scheduled. Check your home insurance policy, as emergency call-out and subsequent repair may be covered. Take photographs of the damage before any work is done as evidence for an insurance claim.

Ask for evidence of public liability insurance, and check whether the roofer is a member of a recognised trade body such as the National Federation of Roofing Contractors (NFRC) or is registered with TrustMark or Checkatrade - these schemes require members to meet minimum standards. Get at least two or three written, itemised quotes so you can compare what is actually being offered, not just the headline price. A reputable roofer will carry out a proper inspection before quoting, explain what they have found and why certain work is needed, and will not pressure you into making a same-day decision.
