New Roofs Twickenham

• St Margarets Conservation Area (TW1): Imposing Victorian and Edwardian villas. Re-roofing demands authentic Welsh Penrhyn or Grade-A Spanish slate, hand-bossed Code 5 lead dormer cheeks, parapet gutter overhauls, and period-compliant ridge capping to meet strict Richmond upon Thames heritage controls.

• Strawberry Hill (TW1, TW2): Historic Gothic Revival and period residences. Re-roofing focuses on handmade plain clay tiles, structural rafter reinforcement, intricate Code 5 lead valleys, and traditional mortar-bedded ridge detailing.

• Twickenham Green & Riverside (TW1, TW2): Period cottages and terraced streets requiring natural slate overhauls, party-wall firewall rebuilds, hand-bossed lead soakers, and breathable membrane underlayment.

• Whitton & Hospital Bridge Road (TW2): Expansive 1930s inter-war semi-detached houses. Re-roofing typically involves interlocking concrete tiles, timber gable overhauls, the replacement of brittle bitumen felt, and modern dry-verge mechanical fixings.

Acoustic Insulation Upgrades for Heathrow Flight Paths

Twickenham and Whitton sit beneath primary flight paths for Heathrow Airport. During a roof replacement, the opportunity arises to significantly reduce interior noise pollution. When we strip the roof to bare timbers, we can install specialized acoustic insulation boards (such as dense mineral wool or acoustic PIR) between and over the rafters before laying the breathable membrane. This targeted upgrade dramatically reduces aircraft noise penetration into loft spaces and upper bedrooms, making a massive difference to quality of life in TW1 and TW2.

Strict Conservation Standards in St Margarets

Properties located within designated conservation areas across St Margarets and Twickenham Riverside are governed by strict directions enforced by the local authority. Replacing an authentic slate or handmade clay tile roof with modern synthetic alternatives violates heritage controls. 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.

"Nail Sickness" & Corroded Fixings on Historic Slate Roofs

Many Victorian properties across East Twickenham still feature original slate roof coverings. After 100+ years, the original iron fixing nails corrode through—a condition known as "nail sickness." While the slates themselves may appear sound, individual slates begin slipping down the roof during windstorms, tearing through old underlay. During a complete re-roof, our crew strips the covering to bare timbers, installs high-performance breathable roofing membranes, and fixes new slates with corrosion-proof copper nails.

A complete pitched roof replacement on a standard Twickenham semi-detached or villa 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 St Margarets?

Like-for-like roof replacements generally fall under Permitted Development and do not require formal council planning permission. However, because areas like St Margarets and Strawberry Hill are designated conservation zones, material approvals apply. We ensure all slates, clay tiles, and leadwork match local heritage guidelines during our free survey.

Do I have to upgrade my loft insulation when getting a new roof in TW1 or TW2?

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 Twickenham completely free?

Yes. John Quilligan visits your property in TW1 or TW2 in person, inspects the roof structure, loft timbers, and chimney leadwork, and provides a clear, itemized written estimate with zero call-out charges.
