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
London's housing is dominated by Victorian and Edwardian terraces, often in yellow London stock brick, with Georgian terraces in central districts and mansion blocks across many inner areas. Outer boroughs have large belts of interwar semis, and there are extensive post-war council estates. Many houses have been split into flats, and conservation areas are widespread.
London Clay shrinks and swells with the seasons, and street trees close to houses can contribute to movement, which affects foundation design.
Building traditions across London also raise conservation and planning questions, so we check those for a new roof in Bexley at the survey stage.
Permissions for a new roof in Bexley
Homes in Bexley come under the regulations for England, summarised below. We don't rely on general rules alone: we confirm the position for your address with the council before a quote goes out.
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
Survey and measure
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.
Your fixed price
The quote arrives in writing, not over the phone. It covers the full scope, the finishes you've chosen, any exclusions and the payment schedule, with a fixed price tied to that specification.
Dates and permissions
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
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 Bexley
Do I need planning permission to replace my roof?
Planning permission is not usually needed to re-roof in similar materials, but it depends on the change, your home's location, whether it is listed or in a conservation area, and which UK nation you live in. Changing the roof shape, height or covering material can need permission. Listed buildings need consent for re-roofing. We check the position for your home before quoting.
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.
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.
What happens at the survey?
We visit your home at a time that suits you, look at the area involved, take measurements and check access, condition and any services that might be affected. We talk through what you want from a new roof, explain the options and answer questions. There is no charge and no obligation; afterwards we send a written quote.
Do I need planning permission in Bexley?
It depends on the work, the size of the project, your property type and whether the building is listed or in a conservation area. Bexley is in England, so England's rules apply. Many smaller jobs need no planning application, but some still need building control approval. We check what applies to your address before quoting.
