Ten Days from Start to Finish: What Happens On Site
A standard pitched roof replacement on a typical South London terrace or semi takes 5 to 10 working days, weather permitting. Here is the step-by-step installation process:
Scaffolding Erection: Full, safe scaffolding is built around your property to provide safe access for our six-man crew across the entire project.
Stripping the Old Roof: Existing tiles, slates, and battens are stripped down to the bare timber deck and safely cleared into our disposal skips.
Timber Inspection & Repair: Every rafter, joist, and wall plate is inspected for wet rot, woodworm, or sagging, with damaged timbers cut out and replaced.
Breathable Underlay & Battens: Modern high-performance breathable membrane and treated counter-battens are installed to current Building Regulations standards.
Tile or Slate Installation: Your chosen concrete tiles, clay tiles, or natural slates are laid to precise weather-proof specifications.
Leadwork & Verge Finishing: Code 4 and Code 5 lead flashings, chimney back gutters, ridge tiles, and dry-verge caps are fitted and sealed.
Site Clearance & Sign-Off: Scaffolding is dismantled, all site waste is cleared, and your 25-year CORC guarantee documents are issued.
When to Stop Patching and Invest in a Re-Roof
Minor tile repairs make sense for localized damage, but repeatedly patching an aged roof reaches a point of diminishing returns. Investing in a full re-roof becomes the smarter financial decision when:
Damage exceeds 30% of the overall roof surface.
Daylight is visible through the roof boards from inside your loft space.
Structural timbers give way or feel soft when tested for rot.
Repeated leaks recur in the exact same area after three or more repair attempts.
Underlay membranes have disintegrated, allowing wind-driven rain to soak directly into internal rafters and ceiling plasterwork.
Choosing the Right Material for Your South London Property
Natural Slate (Welsh & Spanish)
The classic specification for period Victorian and Edwardian properties across Dulwich, Blackheath, and Clapham. Slate is heavy, highly durable, and often required by local planning authorities inside South London conservation areas.
Concrete & Clay Tiles
The standard material across 1930s semi-detached homes in Bromley, Croydon, and Sutton. Clay and interlocking concrete tiles offer an excellent balance of affordability, rapid installation, and a 50+ year operational lifespan.
Flat Roofing Systems (GRP Fibreglass & EPDM Rubber)
Ideal for rear kitchen extensions, dormer conversions, and residential garages. These jointless, cold-applied membranes replace old bitumen mineral felt and won't crack or blister under solar heat.

New Roofs FAQ's
Why do re-roofing quotes vary so drastically between contractors?
Variations usually come down to hidden costs. Some quotes exclude scaffolding, waste disposal, lead flashing replacement, or timber repairs upfront. Our written on-site survey itemizes every single element so you know the total cost before work begins.
Do I need planning permission to replace my roof in South London?
Like-for-like roof replacements do not require formal planning permission. However, if your property is a listed building or located within a designated conservation area (such as parts of Richmond, Dulwich, or Blackheath), specific material approvals may apply. We flag this during your free survey.
What happens if you discover rotten rafter timbers once the old tiles are removed?
We stop, show you the damaged wood up close, explain your repair options, and provide a clear written price for the structural timber replacement before proceeding. You will never receive an unexplained surprise on your final invoice.
How long does a typical complete roof replacement take?
A standard pitched roof on a semi-detached or terrace property takes 5 to 10 working days from scaffolding setup to final cleanup, depending on weather conditions.
Are your on-site surveys completely free?
Yes. John Quilligan visits your property in person to inspect your roof, loft space, and timbers, providing a clear written quote with zero call-out fees or obligations.
