Is a Full Roof Replacement the Right Step?

Repeated leaks, tiles that keep slipping, ridge mortar that has crumbled, or felt that has given up beneath the surface are all signs that ongoing repairs may no longer be cost-effective. A full replacement strips the roof back to the structure, fits new underlay and battens, and starts fresh with a material that should last several decades without the cycle of call-outs and patch repairs.

At Mildenhall Roofers we cover Waterbeach and the surrounding area, and a straight assessment of whether replacement is genuinely needed is worth having before any work is agreed. We also carry out repairs across the area when that is the better option.

What Happens During a Full Roof Replacement

The job starts by stripping all the existing tiles or slates and removing the old felt and battens down to the rafters. The timber structure is checked at this point. Any rotten rafters, damaged ridge boards or other structural issues are dealt with before the new roof goes on, because laying new materials over compromised timbers is a false economy.

New breathable membrane goes on over the rafters, followed by new treated timber battens. The chosen roofing material is then fixed to the battens. All lead flashings at chimneys, valleys, dormers and abutments are replaced at the same time. Ridge and hip tiles are re-bedded and pointed, or dry-fixed systems are used where appropriate.

Scaffolding is required for any full replacement on a pitched roof and should be factored into your budget from the outset. How long the work takes depends on the size of the house, its pitch and the complexity of the roof.

Roofing Materials: Honest Pros and Cons

Choosing a replacement material is not just about cost per tile. You need to think about weight, lifespan, maintenance requirements, and whether the material suits the age and construction of the property. Below is a straightforward comparison of the main options.

Concrete Interlocking Tiles

Concrete tiles are the most widely used replacement material on UK pitched roofs. They are manufactured to consistent sizes, interlock for a weather-tight fit, and are available in a range of profiles and colours.

• Lifespan: typically 40 to 60 years, though they can become porous and prone to surface cracking towards the end of that range.
• Cost: the most affordable pitched roof option, making them a practical choice where budget is a significant factor.
• Weight: heavier than slates and some other options, so the roof structure needs to be capable of supporting them. Most standard UK timber roof structures are built to handle concrete tiles.
• Maintenance: moss growth is common on concrete tiles over time, particularly on north-facing slopes. This does not necessarily shorten the tile life but can cause problems if left for many years.
• Appearance: functional and uniform. Some homeowners find them less attractive than natural materials, though modern profiles are much improved on older flat concrete tiles.

Natural Slate

Natural slate is the premium end of pitched roofing. Good quality slate from established quarries in Wales, Spain or Portugal can last well over 100 years. The slates themselves are unlikely to be the reason the roof fails; it is usually the nails, the felt or the battens that give out first.

• Lifespan: the slate itself can last a century or more. The fixing nails corrode over time, which is why old slate roofs eventually need re-slating even when the slates are in good condition.
• Cost: natural slate is significantly more expensive than concrete tiles, both for the material and for the labour involved in laying it. Expect to pay a meaningful premium.
• Weight: lighter than concrete tiles, which can be an advantage on older properties where the roof structure is lighter.
• Maintenance: individual slates can crack or slip, but the overall maintenance requirement on a well-laid slate roof is low for the first few decades.
• Appearance: the most attractive option for many homeowners, and the best match for older or period properties. It also tends to hold its appeal for buyers.

Reconstituted Slate (Manufactured Slate)

Reconstituted or artificial slates are made from concrete or fibre-cement and shaped to mimic natural slate. They sit between concrete tiles and natural slate on cost, and are worth considering where the look of slate is wanted but the budget does not stretch to natural.

• Lifespan: quality varies significantly between manufacturers. Well-made fibre-cement slates typically last 30 to 50 years. Cheaper products have a shorter and less predictable lifespan.
• Cost: less than natural slate but more than concrete tiles. A reasonable middle-ground option.
• Weight: varies by product but generally lighter than concrete tiles.
• Appearance: better than concrete tiles and a reasonable approximation of slate, though experienced eyes will usually spot the difference. Not always accepted as a like-for-like replacement in conservation-sensitive areas.
• Availability of matching tiles: if a manufacturer changes their range or ceases trading, matching individual replacements can become difficult later. Worth checking that the product you choose has a long track record.

Clay Tiles

Clay tiles have been used on British roofs for centuries and are still produced today. They are more common in certain regions and on older properties, and they offer a warm, traditional look that suits period buildings well.

• Lifespan: clay tiles are among the longest-lasting options. Well-fired clay tiles can last 60 to 100 years or more.
• Cost: more expensive than concrete tiles and can approach natural slate in price, depending on the profile and source.
• Weight: heavier than slates and can be heavier than concrete tiles depending on profile. The roof structure needs to be assessed before specifying clay.
• Maintenance: clay tiles do not suffer from the same porosity issues as concrete tiles as they age. They are frost-resistant when properly fired.
• Appearance: warm and distinctive. The handmade appearance of some profiles suits older properties especially well.

Flat Roof Replacement Materials

For flat or very low-pitch sections of a roof, felt and EPDM rubber are the two main options we fit.

Traditional layered felt is the more familiar material and is still widely used. A properly installed three-layer felt system with adequate falls performs well and is straightforward to repair if a problem does develop later. Typical lifespan is around 15 to 25 years depending on specification and exposure.

EPDM rubber membrane is a single-ply system that is increasingly used on domestic flat roofs. It is lightweight, flexible at low temperatures, and resistant to UV degradation. A well-laid EPDM roof can last 30 to 50 years. Because it is a single sheet with minimal seams, there are fewer joints to fail. The material cost is higher than felt, but the lower maintenance requirements over time often justify it on larger or more exposed flat roof areas.

What to Ask When Getting Quotes

Whichever material you are considering, ask any roofer to specify exactly what they are pricing. The tile or slate brand and grade, the underlay specification, whether battens are pressure-treated, how lead flashings will be detailed, and what happens if structural timber damage is found once the old roof is stripped. Vague quotes lead to unexpected additions once work is underway.

Roof replacement costs vary with the size of the house, the pitch and the chosen material. Natural slate and clay tiles sit at the higher end. Any quote should be itemised rather than a single figure.
