Roof Replacements Croydon

• South Croydon & Central Croydon (CR0, CR2): Victorian and Edwardian terraced streets. Re-roofing typically requires high-grade Welsh or Spanish natural slate overhauls, party-wall firewall parapet upgrades, Code 5 lead valleys, and chimney flashing resets.

• Shirley & Addington (CR0): 1930s inter-war semi-detached properties and mid-century family homes. Primary demand centers on machine-made clay tiles, interlocking concrete tiles, breathable underlayment, and warm-roof insulation upgrades.

• Sanderstead & Selsdon (CR2): Elevated ridge properties subjected to gale-force winds and severe weather exposure. Focus lies on heavy-duty rafter reinforcement, storm-proof dry-verge capping, and mechanical ridge tile fixings.

• Waddon & Purley Way Corridor (CR0): Mixed inter-war housing where original bitumastic underlay felt has turned brittle and disintegrated, requiring complete tile stripping and new treated batten runs.

Integrating Finlock Gutter Removal with Main Re-Roofing in Shirley

Many 1930s–1960s homes in Shirley and Addington feature original Finlock concrete box gutters. When homeowners decide to replace an aging tile roof, leaving old, leaking concrete troughs in place is a recipe for future water ingress. During a full re-roof, our six-man crew can saw away the outer concrete overhang, extend timber rafter feet past the brickwork, and install fresh, insulated uPVC fascias paired with high-capacity deep-flow gutters alongside your new tile roof covering.

Heavy Moss Carpeting & Rafter Sagging in Sanderstead & Selsdon

Properties located on high ridges around Sanderstead and Selsdon absorb heavy shade and dampness from nearby mature woodlands. Over time, thick moss carpets blanket clay and concrete tiles, retaining hundreds of kilograms of rainwater weight. Sustained moisture and weight cause original timber rafters to bow and sag. When we strip your roof down to bare timber, we inspect every joist, sistering bowed timbers or replacing rotten rafters before laying new tiles.

Failed Bitumen Underlayment in 1930s Semi-Detached Homes

Original underlay felt installed in inter-war Croydon homes was made of heavy bitumastic paper. Over 80+ years, heat exposure inside loft spaces turns this material paper-thin and brittle. As tiles shift during winter storms, wind-driven rain tears through the degraded felt and soaks directly into internal ceiling plasterboard. We replace failed underlay with high-performance breathable roofing membranes that allow internal loft condensation to vent outward while blocking exterior rain.

A complete pitched roof replacement on a standard Croydon semi-detached or terrace property typically takes 5 to 10 working days, weather permitting:

1. Scaffolding Setup: Full, safe perimeter scaffolding is erected around your property to provide secure working access for our six-man team.

2. Stripping to Bare Timbers: Existing tiles or slates, old battens, and degraded underlay are stripped away down to bare rafters and loaded into skips.

3. Timber Inspection & Structural Repairs: Rafters, wall plates, and valley boards are checked for rot or sagging, with compromised timbers cut out and replaced.

4. Breathable Membrane & Treated Battens: Modern breathable underlayment and counter-battens are secured to current Building Regulations standards (Part L).

5. Tile or Slate Precision Laying: Your chosen natural slates, clay tiles, or concrete tiles are laid to precise weather-tight gauge lines.

6. Leadwork & Ridge Finishing: Hand-bossed Code 4 and Code 5 lead aprons, step flashings, side soakers, and dry-ridge or mortar-bedded caps are installed.

7. Scaffolding Dismantling & Site Clearance: All site waste is removed, scaffolding comes down, and your 25-year CORC insurance-backed guarantee certificate is issued.

Do I need planning permission for a new roof in Croydon?

Like-for-like roof replacements generally fall under Permitted Development and do not require planning permission. However, if your home is a listed building or situated within a designated Croydon conservation area (such as Chatsworth Road or Upper Norwood), material approvals apply. We handle these checks during your free survey.

Can you remove my old Finlock concrete gutters at the same time as replacing my roof in Shirley?

Yes. Combining Finlock concrete gutter removal with a full re-roof is the most cost-effective approach. Scaffolding is already in place, allowing our crew to cut away the concrete overhang, rebuild timber rafter feet, and install modern uPVC rooflines seamlessly with your new roof tiles.

Do I have to upgrade my loft insulation when getting a new roof in CR0 or CR2?

Yes. Under UK Building Regulations (Part L), replacing more than 50% of your roof covering requires upgrading loft thermal insulation to current standards (typically 270mm). We incorporate this directly into our itemized written quotes.

What happens if rain falls while my roof is stripped off?

We strip roofs in manageable daily sections. At the end of every working afternoon, exposed timbers are completely covered and sealed with high-grade, waterproof breathable membrane, keeping your home 100% watertight throughout the project.

Are your on-site roof surveys in Croydon completely free?

Yes. John Quilligan visits your property in CR0 or CR2 in person, inspects the roof structure, loft timbers, and chimney leadwork, and provides a clear, itemized written estimate with zero call-out charges.
