A roof repair is only as good as what goes back on. Different roof coverings, different flashing types and different flat roof membranes all have their own characteristics - how long they last, how they perform in frost and rain, how easy they are to match to an existing roof, and what they cost. Whatever pitched roof you have, this page explains the materials involved honestly so you can make an informed decision.
Concrete interlocking tiles are the most common covering on post-1960s houses. They're widely available, relatively inexpensive and straightforward to replace like-for-like. A single slipped or cracked concrete tile can usually be swapped in an hour.
The main issue with concrete tiles is colour matching. Concrete tiles fade over time as the surface pigment weathers, so a new tile will often look noticeably lighter or darker than the surrounding tiles for a year or two. That's purely cosmetic and doesn't affect performance, but it's worth knowing if appearance matters to you. Concrete tiles are heavy - a full roof of them puts significant load on the structure - so if you're patching a large area, make sure your roofer checks that the original tile specification matches what's going back on.
Concrete tile roofs typically last 40 to 60 years before requiring full replacement. Localised repairs, done promptly, can extend that comfortably.
Clay plain tiles or pantiles are found on older properties and in areas where they're traditional. Clay is lighter than concrete, ages more attractively (the surface texture weathers to a pleasant matt finish), and can last well over 100 years on a well-maintained roof. Genuine old clay tiles are harder to match than concrete, particularly if the profile or colour is unusual. Reclaimed tiles are often the best answer - a roofer who sources reclaimed stock will give you a far better match than one who only uses new.
Clay tiles are more brittle than concrete and more likely to crack if walked on incorrectly. If someone needs access to your roof for another reason (aerials, solar, chimney work), make sure they know the roof is clay-tiled and are equipped with proper crawl boards.
Welsh and Spanish slate are the two most common types used on UK roofs. Welsh slate is the benchmark for quality - it's dense, hard-wearing and holds its colour well - but it costs considerably more than Spanish slate. Spanish slate varies in quality; the better grades are perfectly serviceable and are widely used for repairs. Cheaper Spanish slate can be more porous and prone to delamination, so it's worth asking what grade your roofer is using.
Slate roofs that were laid with iron nails are subject to nail sickness as those nails corrode. If a few slates are slipping, it may be because multiple nails are failing rather than because each individual slate is damaged. A repair that fixes only the visible slips without investigating the nails is addressing the symptom. A proper inspection will tell you whether isolated repairs are appropriate or whether a re-slating of a section is the more honest answer.
Matching slate for repairs requires knowing the thickness, size and colour of the existing slates. Measure before ordering - a standard-sized replacement slate on a non-standard roof will either be too short to reach the nail fix or too long to sit flush.
Lead is the standard material for flashings around chimneys, dormers, skylights and at abutments where a roof meets a wall. It's been used on British roofs for centuries and, installed correctly, it is genuinely long-lasting - 50 to 80 years is a realistic lifespan for good lead work.
The alternative to lead that some roofers use is a lead-effect self-adhesive flashing tape. This is cheaper and faster to fit, and for a straightforward low-risk junction it can be adequate. However, it doesn't bond well to dusty or contaminated surfaces, it can peel in high temperatures, and it won't last anything like as long as dressed lead. If a tradesperson proposes flash tape on a chimney stack or a high-exposure junction, it's reasonable to ask why and whether lead is an option.
Code 3 lead is used for soakers and stepped flashings; Code 4 is standard for chimney aprons and back gutters; Code 5 is used where heavier cover or durability is needed. These aren't choices you need to make yourself, but knowing they exist means you can ask your roofer what code they're using and why.
Garage roofs, flat extensions and bay window tops are the most common flat sections on a house. Two main materials are used for repairs and replacements: built-up felt and EPDM rubber membrane.
Built-up felt is the traditional system - layers of mineral-surfaced felt bonded together. It's familiar, relatively cheap and widely understood. A well-laid felt flat roof has a typical lifespan of around 15 to 20 years. It's susceptible to blistering in sustained heat and cracking in very cold conditions, and the joins are its weakest points.
EPDM rubber membrane is a single-ply system bonded in one continuous sheet (with far fewer joins). It handles temperature extremes better than felt and is more resistant to ponding water. It costs more to install but generally outlasts felt significantly, with 25 to 30 years being a reasonable expectation for a well-laid EPDM roof. If your felt garage roof has failed more than once in recent years, an EPDM replacement is worth considering rather than another felt overlay.
Ridge tiles are traditionally bedded in sand and cement mortar. Many roofers now use a dry-fix ridge system instead - a mechanical fixing with a flexible seal rather than mortar. Dry-fix systems move with the roof in wind and temperature changes without cracking, and they don't need re-pointing. They cost more upfront but avoid the repeated mortar repair cycle that affects many older roofs.
Chimney flaunching (the sloped mortar cap at the top of the stack) is repaired with sand and cement. The quality of the mix matters - too much cement makes it brittle, and it'll crack again. A proper flaunch is feathered out gradually and keyed into the existing sound mortar before it's applied.
These aren't awkward questions - any experienced roofer will answer them without hesitation. If the answer is vague, that's useful information too.
