A roof replacement, or re-roof, strips the old tiles or slates, battens and felt from a pitched roof and replaces them with a new breathable membrane, battens and covering, repairing timbers and renewing ridges, valleys and flashings at the same time.
We take on a new roof throughout Blackburn and the surrounding BB1 and BB2 postcodes, as well as in Darwen, Accrington and Chorley. The guide range for this work in the North West is £6,600–£14,000 including VAT; where your project falls depends on its size, the materials you pick and how easy the site is to reach. A free survey turns that range into a fixed figure.

Building in Blackburn
East Lancashire mill towns such as Burnley, Blackburn and Accrington have long rows of stone and brick terraces, while Preston is mostly red brick. Lancaster uses sandstone for its Georgian centre, Blackpool and the Fylde coast have guest-house terraces and many bungalows, and interwar and newer estates surround most towns.
Mill-town terraces commonly suit attic conversions, kitchen extensions and repointing. Bungalows on the coast often take loft rooms and porches, and stone properties may need lime pointing and roof repairs.
These patterns matter for a new roof: older walls, roofs and floors in Blackburn can need different materials or extra preparation compared with newer homes.
Planning and building rules in Blackburn
England, Wales, Scotland and Northern Ireland each handle planning a little differently. Blackburn comes under England, covered below, and we raise any questions with the council before your quote is finalised.
Re-roofing a house with similar materials does not usually need planning permission in England. Listed buildings and conservation areas may need consent if the covering changes.
Replacing more than a quarter of a roof’s covering counts as renovation under Building Regulations, so the work is notified and the roof insulation may need upgrading. Bats are protected across the UK; if they roost under roof tiles, soffits or fascias, work stops and a licensed ecologist advises before it restarts.
Rules change and every property is different, so we check the planning history and constraints for your address before we quote.
From survey to handover
Free site survey
A free survey comes first. It gives us what we need to price a new roof properly, including dimensions, existing materials and access for deliveries, and gives you the chance to ask anything you like.
Quote in writing
After the survey we send a quote for a new roof that fixes the price for the scope we've agreed. If you want to change materials or scope, we revise it in writing before anything is booked.
Dates and permissions
Once you accept, we agree start dates, order materials and deal with any planning, building control or neighbour notices the job needs. You'll know who is coming and when before work begins.
Build and hand over
On site, the agreed plan is followed and any change is put in writing first. At completion we do a final clean, go through the snagging list with you and leave you with the relevant documents.

Questions about a new roof in Blackburn
What happens if it rains during the work?
We strip the roof in sections and only remove as much covering as we can replace or protect the same day. New breathable membrane goes on straight after stripping, which keeps most rain out, and we sheet exposed areas at the end of each day and before forecast showers. If heavy rain or high winds are forecast, we pause work. The house is never left open.
How much does a new roof cost?
Re-roofing a typical 3-bed semi costs £6,600–£14,000, including scaffolding, new membrane and battens. As a guide, allow roughly £70–£160 per square metre of roof plus fixed costs for scaffolding and waste. Concrete tiles sit at the lower end and natural slate at the top. Hips, valleys, chimneys and timber repairs add to the price. We confirm a fixed figure after inspecting the roof and loft.
Will my loft insulation and ventilation be improved?
Re-roofing is a good time to improve loft ventilation and insulation. A breathable membrane and eaves or ridge vents keep air moving and reduce condensation in the loft. Building regulations may require insulation upgrades when a large part of the roof is renewed. We check your current insulation and ventilation and include any required improvements in the quote.
Can you combine a new roof with other work?
Yes. Because we manage several trades under one contract, we can plan a new roof alongside other work on your Blackburn home, such as new windows with rendering, or a kitchen refit with an extension. Combining jobs can reduce repeat set-up such as scaffolding, skips and access, and every element is listed and priced in the same written quote.

We cover BB1 and BB2, along with the rest of Lancashire. If your postcode is not listed, get in touch anyway: our coverage is UK-wide, and we can usually arrange a survey wherever you live. Enter your postcode in the guide-price tool or contact form and we will confirm.
