Roofing advice & FAQs

A well-installed concrete or clay tile roof typically lasts 40 to 60 years, while natural slate can last 80 to 100 years or more if the timbers beneath remain sound. Flat roofs using modern EPDM rubber membranes generally last 20 to 30 years; traditional felt flat roofs are often at the end of their life after 10 to 15 years. The actual lifespan depends heavily on the quality of the original installation, maintenance, and how exposed the property is to the elements. Having your roof inspected every few years helps catch small problems before they shorten its life.

If more than 20 to 25 percent of your tiles or slates are cracked, slipping or missing, a full replacement is usually more cost-effective than patching. Other clear signs include sagging roof decking visible from the loft, daylight visible through the roof structure, repeated leaks in the same area despite previous repairs, or a flat roof that has been patched multiple times and is still letting in water. Granules from felt or coating collecting in the gutters, and widespread moss that has lifted tiles, also suggest the roof is reaching the end of its serviceable life. A roofer should inspect the timbers as well as the covering - rotted rafters or purlins change the scope and cost of the work entirely.

If the damage is isolated - a handful of broken tiles, a small section of failed flashing, or a single patch of felt - repair is nearly always the right answer and will be significantly cheaper. Replacement makes more sense when the roof covering is aged across its whole area, when the underlying timbers are compromised, or when repair costs are approaching half the cost of a new roof. A good roofer will tell you honestly which applies to your situation rather than defaulting to whichever job is bigger. Ask for a written breakdown of what they found and why they are recommending the work they are.

A full roof replacement on a typical three-bedroom semi-detached house in the UK costs roughly £5,000 to £12,000, depending on the size of the roof, the material chosen, and how straightforward the access is. Natural slate sits at the higher end; concrete tiles at the lower. Smaller repair jobs - replacing a few tiles, repointing a ridge or resealing flashing - typically cost £150 to £600. Flat roof replacements generally run at £50 to £100 per square metre for EPDM rubber. These are honest ballpark figures; the only way to get an accurate number for your property in Fakenham or nearby is to have someone look at it in person and give you a proper quote.

In most cases, like-for-like roof replacement is covered by permitted development rights in England, meaning no planning permission is needed. However, if you want to change the material, add a roof light, or alter the shape of the roof, you may need to apply. Properties in conservation areas or those that are listed require consent for almost any external alteration, including re-roofing, even if the materials match. Check with your local planning authority before starting work if you are unsure - getting this wrong can mean being required to undo the work at your own cost.

There is no dedicated government grant specifically for roof repairs in England, but some homeowners may qualify for help through the Warm Homes: Local Grant scheme or the Disabled Facilities Grant if the work relates to insulation or accessibility. Local councils sometimes administer small home improvement funds for low-income households, so it is worth checking what your council currently offers. The Great British Insulation Scheme covers loft insulation in some cases, which involves roof space work but not the roof covering itself. If your property is listed or in a conservation area, Historic England occasionally administers grant programmes for historic buildings - eligibility varies, so contact them directly.

A pitched roof has a slope that sheds rainwater quickly and generally lasts longer, which is why it is the standard for most UK houses. Flat roofs (which have a very slight fall rather than being truly flat) are common on extensions, garages, and some 1960s and 70s properties - they are cheaper to build but historically more prone to pooling water and early failure. Modern EPDM rubber systems have improved flat roof performance considerably, and a properly installed modern flat roof can last two to three decades. The choice is rarely yours to make on an existing structure - you work with what you have, and the goal is a well-installed, correctly detailed roof of whichever type.

Most chimney leaks are caused by failed lead flashing - the strips of lead that seal the joint between the chimney stack and the roof slope. Over time, the mortar pointing that holds the flashing in place (called ragwork) cracks and lets water in behind it. The fix is to rake out the old mortar, re-dress the lead, and repoint it properly - a straightforward job for an experienced roofer. If the chimney brickwork itself is spalling, the pointing is crumbling across the stack, or the chimney pot is cracked, additional repointing or rebuilding work may be needed on top of the flashing repair.

Gutters should be cleared of leaves and debris at least once a year - blocked gutters overflow against the fascia board, which rots the timber and can eventually allow damp into the wall or roof structure. Inspect joints and brackets while the ladder is up; silicone sealant on leaking joints buys time, but persistent leaks mean the section needs replacing. Fascias and soffits should be checked for soft spots, peeling paint (on timber boards), or gaps where birds and insects can get in. uPVC replacements for timber fascias and soffits are low-maintenance and worth considering when the timber boards start to fail.

First, contain the water inside - use buckets, towels and move belongings clear, then check the loft space to see where water is entering and whether any timbers are saturated. Do not attempt to get on the roof yourself, especially in wet or windy weather; a fall from a roof height is likely to be fatal. Call a roofer who can attend to make the roof safe and weatherproof - a temporary tarpaulin fixed over the affected area is the standard emergency measure until a proper repair can be carried out in good conditions. Take photographs of the damage inside and out for any insurance claim.

Ask for references from recent local jobs and, where possible, go and look at completed work yourself. A trustworthy roofer will inspect the roof before quoting and explain what they found - be wary of anyone who quotes over the phone without seeing the job. Check that they carry public liability insurance and ask to see the certificate; this protects you if something goes wrong. Avoid paying large deposits upfront, and never pay the full amount before the job is finished and you are satisfied.
