Honest advice
Is Roof Replacement the Right Fix?
A full re-roof is the right answer when the fixings have gone across the whole covering, not when a few tiles have slipped. The honest test is what a surveyor finds when they lift a tile — corroded nail stubs across every plane means the roof is finished, however sound the tiles look.
Tiles or slates lifting by hand across more than one plane
Repeated slipped tiles in different places each winter
Sagging along the ridge line or between rafters
Underlay visibly torn or absent when viewed from the loft
Repair costs over recent years approaching a third of replacement cost
When it is not the answer: If the covering is sound and only the underlay has failed, a strip-and-relay reusing your existing tiles or slates costs substantially less than a full replacement in new material. Read the full guide.
Nail sickness: the slate outlives its fixings, which is why sound covering can usually be relaid.
Customer Reviews
What Local Customers Say
★★★★★
“Got three quotes. This one was the most detailed — itemised line by line so I could see exactly what I was paying for. Went with them.”
Patricia M. · Haughton Green, Darlington
★★★★★
“Full re-roof on our 1930s semi. Came in at the lower end of the quoted range. No surprises on the invoice.”
Graham L. · Cockerton, Darlington
★★★★★
“Quote included scaffold, strip, new felt, battens, tiles and site clearance — everything. Others were cheaper on paper but excluded half of this.”

The process
What to Expect: Roof Replacement in Darlington
1. Full condition survey
Every plane assessed, fixings tested, loft inspected and timber condition established before any price is given.
2. Written specification and quote
Materials named by manufacturer, batten and membrane specification stated, insulation and ventilation upgrades priced separately so you can see them.
3. Building control notification
Replacing more than a quarter of a roof covering is notifiable. We handle the notification and the sign-off.
4. Scaffold and protection
Full scaffold with edge protection and debris netting, planting and paving sheeted, skip sited by agreement.
5. Strip and inspect
The covering comes off, timbers are inspected in daylight for the first time in decades, and anything found is reported and priced before it is done.
6. Re-roof and detail
Membrane, treated battens gauged to the covering, tiles or slates laid and fixed to BS 5534, then leadwork, verges and ridge finished.
7. Cleanup, sign-off and handover
Site cleared, gutters flushed, completion photographs, building control certificate and written guarantee handed over.

Re-roofs are weather-dependent by nature. We never strip more than can be made watertight the same day, and the programme carries contingency for lost days.
Access
Scaffold, Skips & Street Access
A full re-roof always needs scaffold with edge protection — there is no safe alternative. Scaffold is specified for: every full replacement, without exception, plus a debris chute and netting on terraced streets - always itemised in your written quote, never a hidden extra, and we arrange it.
Darlington splits into two access worlds: the railway terraces at Albert Hill, Eastbourne and North Road, where there is no rear vehicle access and scaffold is hand-carried through the house or licensed onto the pavement, and the open post-war estates at Firthmoor, Skerne Park and Whinfield where a wagon can park on the drive. Pavement scaffold and skip permits go through Darlington Borough Council; allow a few working days on streets like Skinnergate, Post House Wynd, Bondgate, Clark’s Yard where space is tight.

What moves the price
Roof area and complexity — hips, valleys and dormers each add labour disproportionate to area
Covering choice: concrete interlocking is cheapest, clay and natural slate cost considerably more
Timber condition found once the covering is off — reported and priced before it is done
Access, particularly on terraces where scaffold is hand-carried through the property
Insulation and ventilation upgrades required to meet current building regulations
Worked example: A three-bed semi on the Whinfield estate — 88m² stripped, breathable membrane, new treated battens, concrete interlocking tiles, dry ridge and verge, eaves ventilation, scaffold and skip — came to £7,150 including building control sign-off.
Staged payments on re-roofs, with nothing payable before materials are on site. A typical structure is a payment when scaffold is up and the roof is stripped, and the balance on completion and sign-off. Never pay a large cash deposit up front for roofing work.
Guarantee
Your Guarantee, Explained
Workmanship guaranteed for 10 years in writing and transferable if you sell. Tiles, slates and membrane carry separate manufacturer warranties, typically 15–30 years depending on product.
Covered: workmanship for 10 years, in writing, transferable if you sell.
On top: manufacturer warranties on materials (terms vary by product).
Not covered: storm or impact damage - that is an insurance matter, and we will document it for your claim.
If a fault appears in covered work, we come back and put it right. No quibbling, no re-charge.
Good to know
Disruption, Mess & Weather
This is the disruptive one: scaffold for a fortnight, real noise during the strip, and a skip on site. We agree working hours in advance and protect everything below. You do not need to stay home for external work - we just need power and access agreed in advance.
Re-roofing runs year-round in the North East, but we plan winter jobs in smaller watertight sections and keep temporary covering on site throughout. Darlington sits in the Pennine rain shadow, so annual rainfall is well below the UK average — what damages roofs here is frost cycling and long, still, damp winters that never quite let a roof dry out.

Survey and Specification for Darlington Properties
Every replacement quote we provide in Darlington starts with a proper roof survey — measuring the area, assessing the existing structure, and confirming the correct materials. Darlington's housing stock is predominantly Victorian terraces, 1930s semis, and post-war concrete tile estates. The correct tile or slate specification varies between these property types, and fitting the wrong material — particularly on period properties in Darlington — can affect both appearance and planning compliance.
What the Re-Roofing Process Involves in Darlington
A standard re-roof in Darlington involves: scaffold erected and secured, full strip of existing tiles, felt and battens, inspection of the timber structure for any decay or damage requiring repair before the new roof goes on, installation of new breathable underlay, treated timber battens, and tiles or slate to specification. Ridge and hips are fitted dry-fix as standard. All lead valley and flashing work is replaced using Code 4/5 lead. The site is left clear at the end of each day. Most 3-bed semis in Darlington are re-roofed in 3–5 working days.
Materials and Climate Considerations in Darlington
Darlington's climate is shaped by its position in the Pennine rain shadow — drier than much of the North East, but with hard winter frosts and repeated freeze-thaw cycles. When specifying materials for re-roofing work in Darlington, we account for these conditions. Breathable modern underlay is specified as standard — it outperforms non-breathable felt in the damp climate and avoids the condensation issues associated with sealed roof voids. Dry-fix ridge and hip systems are recommended on exposed pitches where mortar bedding deteriorates faster than in sheltered urban locations.

We are a Darlington-based roofing contractor covering County Durham and North Yorkshire. Every job we take on across the area is handled by our own team — not passed to a subcontractor we have no control over. We know the specific housing stock, the common failure patterns, and the correct material specifications for properties across the region. This local knowledge directly affects the quality of diagnosis and the durability of the work we carry out.

The written quote you receive is a fixed price for the specific work described, not an estimate subject to revision once we start. We don't quote for the easy parts and add the rest later.

FAQ
Frequently Asked Questions
The five main factors: roof area (m²), complexity (hip roofs, dormers, valleys cost more), material choice (Welsh slate costs more than concrete tile), existing structure condition (rotten timber costs extra), and scaffold access difficulty.
Yes. On a standard 3-bed semi scaffold accounts for £700–£1,400 of the total. Any quote that excludes scaffold is not a like-for-like comparison.
Welsh slate typically adds £800–£2,000 to the cost of a standard semi compared to concrete interlocking tile, depending on whether new or reclaimed slate is used.
Yes. Roofing contractors registered for VAT (which any reputable firm will be) must charge VAT at 20% on roof replacement work, in addition to the labour and material cost quoted.
Typically a 10–20% deposit on contract, balance on satisfactory completion. We never ask for full cash payment before work starts.
A standard 3-bed semi takes 3–5 working days for the roofing work, with scaffold up for 7–10 days total. We give a realistic timeline in the quote.
