When a roof reaches the end of its life, a full replacement is more cost-effective than repeated repairs. We carry out pitched and flat roof replacements across Bury St Edmunds, Ixworth, Elmswell and nearby villages, stripping back to the structure and starting fresh.

Roof replacement means stripping the existing covering back to the structural timbers and starting again with new felt or membrane, new battens, new tiles or slates, and fresh leadwork throughout. It is the right solution when the roof has deteriorated to the point where repairs would be throwing good money after bad. We carry out full roof replacements across Bury St Edmunds and the surrounding towns and villages, including Ixworth and Elmswell.
A well-built roof can last 50 to 80 years or more, depending on the materials used and how well it has been maintained. The felt underlayer beneath the tiles typically has a shorter life than the tiles themselves, and when it fails, water gets into the roof space even if the tiles look intact from the ground. Other signs that replacement is the more sensible option include:
If your roof is showing several of these signs, a full replacement is worth costing up. In many cases, the price difference between extensive repairs and a full replacement is smaller than homeowners expect, and a replacement removes the problem rather than postponing it.
The job starts with scaffold. Safe access to the full roof is not optional - it affects the quality of the finished work as well as the safety of everyone involved. Once scaffold is in place, the existing tiles, battens and felt are stripped and removed from site.
With the timbers exposed, every rafter, purlin, ridge board and hip rafter is checked. Timber that is soft, cracked or undersized for the loading it carries is replaced. This stage is important because covering over poor timbers with new materials simply delays the same problems. Once the structure is sound, a new breathable roofing membrane is fixed, followed by treated tanalised battens set at the gauge required for the tile or slate being laid.
Tile selection is worth taking seriously. Properties in and around Bury St Edmunds vary considerably in age and style. Older and period properties often look best with traditional clay plain tiles or pantiles. Modern detached homes may suit concrete interlocking tiles. Natural Welsh slate or reclaimed materials suit certain property types where budget allows. The weight of the tile matters too - some older roofs were designed for lighter coverings, and switching to heavier concrete tiles without checking the rafter sizes can cause problems over time.
Flat roofs on extensions, garages and outbuildings have a shorter lifespan than pitched roofs, and replacement is a common job. The two main systems used in domestic flat roof replacement are built-up felt and EPDM rubber membrane.
A quality built-up felt system uses multiple layers bonded together to form a waterproof deck. It has been used successfully for decades and, when installed with correct falls and good detailing at upstands and edges, performs well. EPDM rubber is a single-sheet membrane that covers the whole roof area with very few joints. Because most flat roof failures occur at seams and edges, fewer joints mean fewer potential failure points. EPDM is now a well-established choice for domestic flat roof replacement and typically outlasts standard felt by a considerable margin.
Regardless of the system chosen, falls must be correct. A flat roof with inadequate falls will pond water, and standing water shortens the life of any covering material. If the falls on an existing flat roof are wrong, this is the time to correct them - adding insulation or adjusting the firring pieces before the new covering goes on.
A roof replacement is the right time to replace all lead flashings rather than trying to re-use old material. Lead around chimney stacks, in valleys, at abutments with walls, and around skylights or roof windows is what keeps water out at every junction point. Old lead that has been pointed over with mortar repeatedly, or that has cracked due to thermal movement, should come off and be replaced with new. Code 4 lead is standard for most flashings; Code 5 is used where sheets are larger or more exposed.
Chimneys that are no longer in use can be capped at the time of replacement, which removes an ongoing maintenance liability. A chimney that is not being used but is left open to the weather will eventually allow water ingress, and the stack itself may deteriorate faster without adequate weatherproofing at the top.
Guttering, fascias and soffits are closely linked to the roof, and a replacement is a practical time to address them if they are deteriorating. Wooden fascia boards rot from behind when gutters overflow or when the roofline allows water to track back. Replacing them with uPVC or a treated timber alternative at the same time as the roof avoids the need to return and re-scaffold later. New guttering fitted at the correct fall ensures water drains freely without pooling at low points and overflowing onto walls.
Existing skylights and roof windows are exposed during a roof replacement. If a skylight is old or leaking around its frame, this is the most cost-effective moment to replace it, because the surrounding tiles are already off. Fitting a new roof window at a later date means lifting and re-laying tiles that have just been put down, which adds unnecessary cost and disruption.
Most reputable tile, slate and membrane manufacturers back their products with material warranties, which are separate from any workmanship consideration and run with the material itself. It is reasonable to ask what manufacturer backing comes with the materials being used on your roof. EPDM membranes from established manufacturers typically carry long material warranties. Clay and concrete tiles from major producers are usually backed for several decades. These are manufacturer commitments on the product, not workmanship promises from the installer.
A full pitched roof replacement on a three-bedroom semi-detached house typically costs between £5,500 and £10,000 in the Bury St Edmunds area, depending on tile choice, roof complexity and the amount of timber work required. Larger detached homes or those with complex roof shapes - multiple hips, valleys, dormers or chimney stacks - will cost more. Flat roof replacement on a standard garage or single-storey extension generally falls between £1,200 and £3,500, depending on size and the covering system used.
These are broad ranges. Getting an accurate figure means having the roof inspected and a detailed quote produced based on what is actually found.
