If you are facing a roof replacement in Necton, knowing exactly what the job involves - and what to expect at each stage - takes a lot of the uncertainty away.
A full roof replacement is not a small job. For most homeowners it happens once, maybe twice in a lifetime of owning a property. Knowing what each stage involves means you can ask the right questions, spot if something is being skipped, and understand why the job takes as long as it does.
Dereham Roofers covers Necton and the surrounding area, and what follows is an honest account of how a roof replacement actually unfolds from the first visit to the final tidy-up.
Before any price can be given or work planned, someone needs to look at the roof properly. A quick glance from the ground is not enough. A thorough inspection means getting up to eaves level on a ladder, checking the ridge, hips and valleys, examining the flashings around any chimneys or dormers, and going into the loft space to look at the underside of the roof deck.
The loft inspection is particularly telling. From inside you can see whether the underlay is brittle or perforated, whether there is evidence of water ingress, and whether the rafters and boarding are sound. If the structure is damaged, that needs to be factored into the scope of work before pricing starts.
You should come away from the inspection knowing what condition the roof is in, what the roofer is proposing to do, and why. If you are just handed a price without an explanation, ask for one.
Safe access to a pitched roof requires scaffolding. This is not optional and should not be substituted with ladders or a cherry picker for a job of this scale. A proper scaffold platform around the perimeter of the roof protects both the workers and the property below.
Scaffolding is typically erected a day or two before the roofing work begins. The scaffold company erects it independently, and your roofer coordinates the timing. On a standard two-storey house, scaffold is usually in place within a few hours. It stays until the job is complete and signed off, after which the scaffold company returns to strike it.
The cost of scaffolding is usually included within the overall replacement quote. If it is quoted separately, make sure you understand what is and is not covered.
Once the scaffold is up, the stripping stage begins. This means removing everything down to the bare roof deck - all the tiles or slates, the old battens and the old underlay. On a typical semi-detached house this takes one to two days depending on the size and the weight of the existing materials.
Stripped materials are loaded into a skip or taken away by the roofers. You should agree in advance whose responsibility the disposal is and whether a skip will be sitting on your drive or the road outside.
During stripping, the full condition of the deck becomes visible for the first time. Rotten or damaged sections of boarding or rafters can only properly be assessed once the tiles are off. This is why reputable roofers price for structural repairs separately, or flag them as a potential additional cost - it is genuinely not always possible to know the full extent until the roof is open.
If rotten rafters, failed boards or damaged wall plates are found during stripping, these must be repaired before the new covering goes on. This is not an upsell - it is a structural necessity. Laying new tiles on a compromised structure creates an unsafe roof and means the problem returns.
Structural repairs typically involve cutting out and splicing in new sections of rafter, replacing individual boards, or renewing the wall plate timbers at eaves level where these have deteriorated. The extent varies significantly from one property to the next. An older house that has had water getting in for years will need more structural attention than one where the roof was watertight until recently.
With the structure sound, new underlay goes down before any battens or tiles. On modern replacements this should be a breathable membrane rather than the original bitumen felt. Breathable underlays allow moisture vapour to escape from the roof space, which protects the structural timber from condensation over time.
The underlay is lapped correctly at every course and dressed properly into the gutters at eaves level. This is unglamorous work that nobody sees once the tiles are on, but it is one of the most important parts of the job. A poorly lapped or badly dressed underlay will let water into the structure despite looking fine from the outside.
New treated timber battens are fixed horizontally across the roof at the correct gauge (spacing) for the chosen tile. The gauge matters: too wide and tiles will not overlap properly, allowing water to penetrate; too tight and the tile layout will not work out correctly at the ridge.
Battens should be pressure-treated against rot and fixed securely into the rafters, not just into the boarding. On a well-set-out batten job, the roofer has calculated the gauge before the first batten goes down so the spacing is consistent from eaves to ridge.
Tiling is the stage most people picture when they think of a roof replacement. Tiles or slates are fixed course by course from the eaves upward. Every tile is mechanically fixed - nailed, clipped or both - not just resting on the battens. Current practice requires full mechanical fixing across the whole roof, not just on the perimeter courses.
Hip and valley details require careful cutting and fitting. Valleys can be formed with lead or purpose-made valley troughs. At the ridge, modern dry-fix ridge systems use a ventilated batten and mechanical fixings rather than mortar bedding. Dry-fix is more durable than mortar in the long run because it does not crack or shrink, and it allows some ventilation at the ridge.
Flashing around chimneys, dormers and any abutments is cut and dressed in lead. Lead flashing done properly involves soaking it into the mortar joints of the masonry and folding it correctly over the tile surface. Sealant-only flashings are not adequate for a long-lasting result.
Once the roof covering is complete, gutters and downpipes should be checked and, where necessary, replaced or re-fixed. Roofing work can disturb existing fixings, and a new roof that drains into a failing gutter is a problem waiting to happen.
A final check should cover ridge alignment, flashing dress, tile fixing at vulnerable points such as verges and eaves, and the clearance of any debris from valleys and gutters.
Once the roof is complete and you are satisfied, the scaffold is struck and removed. All roofing waste, offcuts and packaging should leave with the roofers or the skip. The site should be left as clean as it was found.
Before the scaffold comes down is the right time for a final walk-round with the roofer so you can see the finished work from the scaffold platform if you want to, and raise anything you are not happy with while access is still easy.
On a standard three-bedroom house, a full roof replacement from stripping to completion typically takes three to five working days for the roofing work itself, not counting scaffold erection and strike. Larger or more complex roofs - multiple hips, dormers, or significant structural repairs - take longer. Weather delays are a fact of roofing life; your roofer should keep you informed if the schedule changes.
