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.

Local housing and a new roof
Kent's older buildings include oast houses, weatherboarded cottages, Wealden timber-framed houses and Kentish ragstone walls. Medway towns have long rows of Victorian terraces, Margate and Ramsgate have Regency and Victorian seafronts, and Ashford, Maidstone and Dartford have seen large new estates alongside interwar and post-war housing.
Victorian terraces suit loft rooms and rear extensions; weatherboarded and timber-framed buildings may need cladding repairs and lime work. Newer estate homes often take garage conversions, porches and landscaping.
Whatever era your Dartford home dates from, we plan a new roof around how it is actually built rather than a one-size-fits-all specification.
Planning and building rules in Dartford
Because Dartford falls under England's rules, the guidance below is the version relevant to you. Before sending a price, we check your property's position with the council.
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.
What happens after you get in touch?
Survey and measure
Book a visit and we'll come to you. The survey covers measurements, the state of what's there now and any obvious constraints, so the price that follows is based on your actual home, not an average.
Written quote
You get the price in writing, itemised so you can see where the money goes. As long as the specification stays the same, that is the price you pay for a new roof.
Booking the work
We handle the paperwork side: checking whether planning permission or building control approval is needed, submitting applications where they are, and scheduling the trades and materials around your dates.
Build and hand over
Our trades complete a new roof while your point of contact keeps you updated. When everything is finished, we clear the site, take away waste and go through the result with you before handover.
How we work
Common questions
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 Dartford 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.
How long does a roof replacement take?
Re-roofing a typical semi-detached house takes around one to two weeks once scaffolding is up, depending on the roof's size, complexity and the weather. Smaller terraced roofs can take a few days. Scaffolding usually goes up a day or two before work starts and comes down once everything is inspected. We give you a programme and keep the roof weathertight overnight.
Is the price fixed?
Yes, for the specification we agree. Your written quote sets out exactly what is included at a fixed price. It only changes if you ask for something different, or if a problem the survey could not reasonably reveal later needs extra work. In either case we explain the change and confirm it in writing before going ahead.
How do I know if I need a new roof or just repairs?
A roof needs replacing when problems are widespread, not isolated. Signs include many slipped, cracked or porous tiles, sagging between rafters, daylight or damp in the loft, perished felt that crumbles to the touch and repeated leaks in different places. A few slipped tiles or a loose ridge can usually be repaired. We inspect from outside and inside the loft and tell you honestly which is needed.
How long will a new roof last?
A well-installed roof lasts for decades. Concrete tiles typically last around 50 years or more, clay tiles longer, and natural slate can last a century with proper upkeep. Lifespan depends on the quality of materials, fixings, ventilation and leadwork, and on how exposed the roof is. Keeping gutters clear and fixing slipped tiles quickly helps it reach its full life.
