If your roof in March is beyond repair, a full replacement is the most reliable way to protect your home for decades to come.
Not every roofing problem calls for a full strip and relay. But there are clear situations where replacement is the only sensible route. If a roof has widespread tile failure, a broken-down felt underlay, rotten or bowed battens, or has been repaired repeatedly without lasting results, a full replacement tackles all of it in a single job. Patching over a failing system only delays the inevitable and can cost more in total than starting fresh.
We work on roof replacements across March and the surrounding area, covering both older terraced properties and modern detached houses. The process and materials are largely the same across property types, though the structural condition of an older roof sometimes throws up extra work once the old covering comes off.
A full replacement means stripping everything back to the bare rafters: old tiles or slates, the underlay, and the battens. Once the structure is exposed, the rafters are checked for rot, movement or damage. Any weakened timber should be sistered or replaced before the new roof goes on, because covering a soft rafter is simply building a future problem into your new roof.
New breathable membrane goes down first, then treated tiling battens, then the new covering. Natural slate and reconstituted slate are both available where appearance is the priority. Ridge tiles are fitted with either a dry-ridge mechanical system or traditional mortar bedding, and all lead flashings at chimneys, abutments and valleys are renewed as part of the job.
On a standard semi-detached house, full replacement costs typically fall between £5,000 and £9,000, depending on size, pitch, access and material choice. Larger or more complex roofs cost more. Always ask for an itemised quote that names the materials by type and grade, so you know exactly what you are buying.
The distinction between a roof that needs repair and one that needs replacing is not always obvious from the ground. Some indicators that replacement is worth considering:
A physical inspection from inside the loft and from the roof surface itself is the only reliable way to assess the true condition. An assessment based solely on what is visible from the ground will miss most of the detail that matters.
If you have identified or suspected a roof problem in March and have a roofer coming out to survey, there are practical steps you can take in the meantime to limit damage. Equally, there are things people do instinctively that can make the situation worse or create additional hazards. This is worth reading carefully.
If water is getting into the roof space, move anything stored in the loft away from the affected area. Even a slow drip onto cardboard boxes or stored belongings can cause significant damage over a few days. Place buckets under any active drips, but check them regularly: an unattended bucket that overflows defeats the purpose.
If water is tracking along a rafter or joist rather than dripping straight down, you can sometimes guide it into a bucket by tying a piece of string around the timber and letting the string hang into the container. This is a practical short-term measure, not a fix.
Mineral wool insulation that gets wet loses most of its thermal value and takes a very long time to dry out. It can also mask ongoing damp and encourage mould growth on the timbers beneath it. If the insulation in the affected area is wet, remove it temporarily and allow the timber to dry if conditions permit. Replacement insulation is relatively inexpensive and straightforward to lay when the roof work is complete.
Take clear photographs of any water stains, damp patches, damaged internal plasterwork and the loft space before work begins. If you need to make a household insurance claim, insurers will want evidence of the pre-existing condition and how quickly the damage progressed. Photographs with timestamps are more useful than descriptions after the fact.
This is genuinely important. Domestic roofs are steep, surfaces are often slippery, and working at height without the correct equipment is a significant risk. A fall from a first-floor roof height is frequently fatal. Even a flat or low-pitch section is more dangerous than it looks from ground level.
Beyond the personal safety risk, walking on tiles that are already in poor condition can dislodge or crack them, creating new entry points for water and making the problem worse before the roofer arrives. Do not attempt to apply temporary sealant, roofing tape or any other product to the exterior surface without professional guidance. Products applied incorrectly can trap water rather than exclude it, and some sealants create problems for the roofer when the proper work is done.
In some situations, particularly after storm damage, a roofer may fit a temporary tarpaulin or protective sheet before the main work can begin. This is a legitimate short-term measure when done by someone who knows how to secure it properly. A sheet that is not correctly weighted and tied can become a significant hazard in wind, or can channel water into parts of the roof that were previously unaffected.
If a roofer or contractor suggests fitting a temporary cover, ask exactly how it will be secured and check it has not shifted after any period of wind. A temporary cover is not a repair and should not be left in place indefinitely.
Well-meaning advice from neighbours or online searches can lead people to apply products or take actions that complicate the professional repair. Roof coatings applied to the outside of a failing roof - the thick spray or brush-on products sometimes advertised - do not address the underlying failure. They can seal moisture in, interfere with ventilation and make a professional assessment harder because the coating hides what is happening underneath. If anyone suggests a coating as an alternative to proper inspection and replacement, treat that suggestion with caution.
Replacing a roof like-for-like generally does not require planning permission. If your home is in a conservation area or is a listed building, additional rules apply and material choice may be restricted. Check with the local planning authority before work starts if there is any doubt, not afterwards.
We carry out roof replacements across March and the surrounding area. If you are not sure whether we cover your location, call and ask.
If your roof is showing signs of serious deterioration, the most useful thing you can do is arrange a proper inspection before the situation worsens. Call Ely Roofers to book a roof survey in March, and we will give you a clear, honest assessment of whether a repair or a full replacement is the right course of action for your property.
