If your roof is showing signs of age or failure, it is worth considering whether a full replacement makes more sense than further repairs.

Most homeowners do not replace a roof until something forces the issue. That is understandable - a new roof is a significant expense, and nobody wants to spend money on it unnecessarily. But delaying past the point where repair is practical costs more in the long run, both in emergency call-outs and in hidden damage to the structure beneath. Knowing the warning signs early gives you time to plan, budget and choose materials properly rather than scrambling after a leak has already soaked through the ceiling.
We install new roofs for homeowners in Easton and across mid-Norfolk using quality materials chosen to suit local weather conditions. Whether your existing roof is clay or concrete tile, natural slate or a flat felt system, we can assess what you have, explain your options honestly, and carry out the full replacement from stripping back to the final ridge.
A single slipped tile or a failed flashing is a repair job. A roof that is failing across its whole surface is a different matter. The distinction matters because sending a roofer up to patch individual tiles on a deck that is twenty years past its life expectancy is money spent twice. These are the signs that a full replacement is worth considering seriously.
Understanding why a roof fails helps you make better decisions about replacement. It also protects you from being told you need a new roof when a targeted repair would do the job.
Nail sickness is one of the most common causes of widespread tile failure on older roofs. The wire nails used to fix slates and plain tiles from the mid-twentieth century onwards corrode slowly over decades. Once the nail has corroded through, the tile or slate is held only by its nib resting on the batten below. Wind lifts them off. You can see this happening gradually - tiles start to slip out of line without any obvious storm damage. Once nail sickness is confirmed across a roof, re-nailing the whole slope is usually more cost-effective than patching, and often a full strip and relay is the right call if the battens are also softened by years of moisture.
Batten rot goes hand in hand with nail sickness and with failed underlay. Battens are the horizontal timbers that run across the rafters and carry the weight of the tiles. They sit in a wet environment by nature - water that gets past the tiles is supposed to run down the underlay and into the gutters, but if the underlay has failed, moisture sits on the battens. Soft or crumbling battens cannot hold fixings, which means new tiles laid on old battens will work loose again quickly. Any proper re-roof strips the old battens and replaces them as part of the job.
Thermal movement cracks mortar bedded ridges and hips over years of heating and cooling. A ridge that has lost its pointing is an open entry point for water along the whole top of the roof. Repointing buys time on an otherwise sound roof, but on an older roof it often only exposes the next problem underneath.
Condensation damage from below is less well understood by most homeowners but causes real structural harm. A poorly ventilated cold loft builds up moisture from the living space below. That moisture condenses on the cold underside of the roof deck and saturates the insulation, the felt and eventually the timbers. Replacing a roof without improving the ventilation and insulation arrangement below it risks the new roof suffering the same fate.
Original poor workmanship shortens a roof's life significantly. A roof laid with insufficient lap on the tiles, with the wrong gauge for the pitch, or with valleys cut and bedded rather than lead-lined, will fail years before a properly installed one. This is one reason why getting the installation right first time matters more than saving a few hundred pounds on a quote.
The material you choose affects the look of your home, how long the roof lasts, and how it performs in mid-Norfolk's climate. There is no single right answer, but there are better and worse choices for particular roof types and pitches.
Natural slate is the most durable material available for pitched roofs. Good quality Welsh or Spanish slate, fixed correctly with adequate lap for the roof pitch, can last well over a century. It is also the heaviest material, so the roof structure needs to be sound enough to carry it. Natural slate suits traditional properties and is often required for planning purposes in conservation areas or on listed buildings. It costs more to buy and takes longer to lay than concrete tile, which is reflected in the overall price.
Concrete interlocking tiles are the most widely used material on post-war housing. They are cost-effective, available in a wide range of profiles and colours, and quicker to lay than plain tiles or slate. The main drawback is weight - they are heavier than many people expect - and they can look harsh on older properties where the original roof was plain clay tile. Manufacturers typically quote fifty years for concrete tiles, though performance varies with the quality of the original install.
Clay plain tiles suit period properties well and are lighter than concrete interlocking tiles. They weather naturally to a softer colour over time. They require a steeper pitch to perform correctly and take longer to lay because the tiles are smaller. Reclaimed clay tiles are sometimes used on older properties to match an existing roof or a neighbouring elevation, though sourcing good quality reclaimed stock takes time.
EPDM rubber membranes are now widely used on flat and low-pitch roofs as an alternative to traditional built-up felt. EPDM (ethylene propylene diene monomer) is a single-ply rubber sheet bonded to the deck. It is flexible, tolerates thermal movement well, and does not crack the way felt does as it ages. Manufacturers of EPDM membranes typically quote fifty years of expected performance. Felt built-up systems are still used and work well when installed correctly, but EPDM has become a preferred choice on new flat roof installations.
A replacement roof is a multi-stage job. Knowing what is involved helps you assess quotes and understand what you are paying for.
The first stage is stripping. Every tile, slate or flat roof covering comes off, along with the old battens and underlay. This is the only way to properly inspect the deck and the structural timbers beneath. Any rotten or damaged rafters or structural boarding are replaced at this point, before anything new goes on top.
New underlay goes down next. On a pitched roof this is a breathable membrane that allows moisture vapour from the loft space to escape while preventing wind-driven rain from reaching the deck. New treated timber battens are fixed through the underlay into the rafters at the correct gauge for the tile or slate being laid.
The new tiles or slates are then laid from the eaves upward, fixed at the correct lap for the pitch. Lead or aluminium flashing is dressed into all abutments - where the roof meets a wall, a chimney or a dormer. Valleys are cut and lined in lead or valley trims depending on the specification. The ridge is mechanically fixed with dry-fix systems or, where specified, bedded in mortar and pointed.
At every stage the work needs to meet the requirements of BS 5534, the British Standard for slating and tiling. A good roofer will follow this as a matter of course rather than as a box-ticking exercise. It covers minimum lap, batten gauge, fixing specifications for different wind zones and tile types, and requirements for underlay.
A new roof on a typical three-bedroom semi-detached house in mid-Norfolk using concrete interlocking tiles typically costs between £6,000 and £10,000 in current market conditions, depending on the size of the roof, the pitch, the number of hips and valleys, and whether any structural timber needs replacing. Natural slate adds to the material cost and the labour time, so a like-for-like slate replacement on a similar house typically runs between £9,000 and £15,000 or more depending on the slate specification. Flat roof replacements vary widely with size and material choice - an EPDM replacement on a typical rear extension flat roof is usually between £1,500 and £4,000.
Scaffolding is a necessary cost on any roof replacement and is typically included in the overall quote from a roofer who manages the project. It adds to the cost but there is no practical alternative for safe access on a pitched roof of any size.
These figures are a guide for planning purposes. The only way to get an accurate cost for your property in Easton is to have the roof inspected and measured. Ask any roofer you approach to provide a written, itemised breakdown so you can compare quotes properly.
Getting multiple quotes is sensible on a job of this size. But comparing quotes is only useful if they are for the same scope of work. Here are questions worth asking every roofer you invite to quote.
A roofer who cannot or will not answer these questions clearly before you sign anything is a roofer worth walking away from, regardless of price.
In most cases, replacing a roof with the same or similar materials is permitted development and does not require planning permission. The exception is if your property is in a conservation area, is a listed building, or if you are proposing to change the roof shape or add a dormer. If you are in any doubt, check with the local planning authority before work starts rather than after.
Building regulations approval is required where the roof replacement involves structural work or where insulation is being altered as part of the project. A competent roofer will advise you on whether a building regulations application is needed for your specific job.
If you have noticed any of the warning signs described above, the right starting point is an inspection from someone who can get onto or close to the roof and give you an honest opinion. A roof that looks bad from the ground is not always failing across its whole surface - and a roof that looks fine from street level sometimes has serious problems that are only visible on close inspection.
We carry out roof surveys for homeowners in Easton and the surrounding area. If repair is the right answer, we will tell you. If the evidence points to replacement, we will explain why and give you a clear breakdown of the work involved. Call us to arrange a survey of your roof before the next round of wet weather arrives.
