New Roofs New Malden

• Old Malden Conservation Area (KT3): Historic village properties and period cottages. Re-roofing requires genuine Welsh SVT slate, handmade clay plain tiles, heavy-duty rafter reinforcement, Code 5 lead valleys, and period-compliant ridge capping under Kingston conservation guidelines.

• Motspur Park & Westbury Road (KT3): 1930s suburban semi-detached and detached homes. Re-roofing typically centers on plain clay tiles, machine-made interlocking concrete tiles, timber gable overhauls, 1930s tile-hanging repairs, and dry-ridge mechanical fixings.

• Burlington Road & High Street Corridor (KT3): High-density Victorian and Edwardian terraced streets needing natural Welsh or Spanish slate overhauls, party-wall firewall rebuilds, hand-bossed lead soakers, and breathable membrane underlayment.

• Malden Way & Shannon Corner Fringe (KT3): Suburban family homes where original bitumastic underlay felt has turned brittle, requiring complete tile stripping, new treated batten runs, and warm-roof insulation upgrades.

Heavy Clay Tile Load & Timber Rafter Sagging in Motspur Park 1930s Semis

The prominent gabled roofs characteristic of Motspur Park and Westbury Road were originally clad in heavy plain clay tiles. Over 90+ years, sustained dead weight combined with moisture absorption causes original 3x2-inch softwood rafters to bow and sag. When our six-man team strips your roof to bare timbers, we evaluate every structural joist, sistering bowed rafters with treated timber and reinforcing hip beams to guarantee a perfectly flat, structurally sound foundation before laying new tiles.

Heritage Compliance in Old Malden Conservation Area

Properties located within the designated Old Malden Conservation Area are subject to strict architectural controls enforced by the Royal Borough of Kingston upon Thames. Replacing an authentic clay plain tile or natural slate roof with synthetic concrete substitutes violates planning regulations. We source genuine SVT Welsh Slate, Grade-A Spanish slate, and handmade clay plain tiles, pairing them with traditional leadwork and mortar-bedded ridge caps to ensure 100% compliance and a 75+ year operational lifespan.

Paper-Thin Bitumen Underlay Breakdown & Insulation Upgrades

Original bitumen felt underlay installed in 1930s and period New Malden homes turns paper-thin and brittle after decades of attic heat exposure. When slates or tiles shift during winter storms, wind-driven rain tears through the degraded felt and soaks into ceiling plasterboard. We replace failed underlay with high-performance breathable roofing membranes that allow internal loft condensation to vent outward while blocking wind-driven rain.

A complete pitched roof replacement on a standard New Malden 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 the Old Malden Conservation Area?

Like-for-like roof replacements generally fall under Permitted Development and do not require formal council planning permission. However, because Old Malden is a designated conservation area, material approvals apply. We ensure all slates, clay tiles, and leadwork match local heritage guidelines during our free survey.

How do you handle shared party-wall roof sections with neighbors in Motspur Park?

We liaise with your neighbor before work begins. We install clean bonding gutters or shared lead valleys along the party line, ensuring a seamless, watertight junction between your new roof covering and the adjoining property.

Do I have to upgrade my loft insulation when getting a new roof in KT3?

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 New Malden completely free?

Yes. John Quilligan visits your property in KT3 in person, inspects the roof structure, loft timbers, and chimney leadwork, and provides a clear, itemized written estimate with zero call-out charges.
