New Roofs Kew

• Kew Green Conservation Area (TW9): Grade-listed Georgian and Regency townhouses. Re-roofing demands authentic Welsh Penrhyn or Grade-A Spanish slate, hand-bossed Code 5 lead dormer cheeks, parapet gutter overhauls, and period-compliant lime-bedded ridge capping to satisfy Richmond upon Thames heritage controls.

• Kew Road & Botanic Gardens Buffer Zone (TW9): Grand Victorian villas featuring complex multi-pitch roofs. Re-roofing focuses on handmade plain clay tiles, reclaimed slates, timber rafter reinforcement, Code 5 lead valleys, and warm-roof insulation upgrades.

• Lichfield Road & Ennerdale Road (TW9): Edwardian terraced and semi-detached properties requiring natural slate overhauls, party-wall firewall rebuilds, hand-bossed lead soakers, and breathable membrane underlayment.

• Mortlake Road & North Sheen Borders (TW9): Mixed suburban housing where concrete tile re-roofing is often combined with brittle felt removal, new treated batten runs, and dry-verge capping.

UNESCO Buffer Zone & Conservation Compliance on Kew Green

Properties surrounding Kew Green and along the perimeter of the Royal Botanic Gardens are protected by strict conservation policies enforced by the London Borough of Richmond upon Thames. Replacing an authentic Welsh slate or handmade clay tile roof with synthetic substitutes violates planning regulations and triggers enforcement action. 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 an 80+ year operational lifespan.

"Nail Sickness" & Corroded Fixings on Historic Kew Road Slates

Many Victorian properties across Kew still feature original slate roof coverings installed with iron nails. After more than a century, these nails corrode through—a failure known as "nail sickness." Individual slates slip out of line, exposing the degraded bitumen felt underneath to driving rain. During a complete re-roof, our crew strips the covering to bare rafters, replaces failing battens, installs high-performance breathable roofing membranes, and secures every new slate with corrosion-proof copper nails.

River Thames Wind Uplift & Moisture Ingress near Kew Bridge

Properties located near the riverbank experience strong wind gusts and damp air currents blowing along the Thames corridor. Standard fixing patterns are insufficient against these uplift pressures. We conduct site-specific wind-load assessments, installing factory-graded 25x50mm BS5534 treated battens fixed with ring-shank nails, securing every perimeter slate or tile to eliminate the risk of storm dislodgement.

To ensure seamless execution on historic and high-value properties in Kew, we replace roofs through a rigorous four-stage framework:

Stage 1: Heritage Permitting & Weather-Encapsulated Access

We handle all local authority logistics, obtaining necessary scaffold permits and street licenses from Richmond Council. We erect fully netted, independent perimeter scaffolding. Work is executed in weather-monitored sections, ensuring exposed roof decks are sealed with heavy-duty waterproof breathable underlay before our team leaves each afternoon.

Stage 2: Structural Deck Verification & Rafter Restoration

Old tiles, battens, and degraded bitumen felt are stripped down to bare timbers. Our team surveys every structural joist, purlin, and wall plate. Any timber damaged by wet rot is excised, deflected rafters are sistered with structural C24 treated timber, and valley boards are reinforced to create a rigid, level deck.

Stage 3: High-Vapour Permeability & Part L Thermal Upgrades

To meet current UK Building Regulations (Part L), we install high-density quilt insulation (up to 270mm depth) or rigid PIR insulation boards across ceiling joists. We then install a heavy-duty, tear-resistant breathable membrane and counter-batten with factory-graded 25x50mm BS5534 treated timber battens secured with ring-shank nails.

Stage 4: Authentic Double-Lap Slate Installation & Master Leadcraft

Natural slates or handmade clay plain tiles are precision-laid to exact gauge lines using copper fixings. Code 5 milled lead is bossed on-site for dormer cheeks, chimney flashings, concealed valley gutters, and parapet junctions. Ridge tiles are bedded in authentic lime mortar or secured with mechanical dry-fix systems, scaffolding is dismantled, the site is immaculately cleared, and your 25-year CORC guarantee certificate is issued.

Do I need planning permission for a new roof in the Kew Green Conservation Area?

Like-for-like roof replacements using matching authentic materials (such as natural slate and clay ridge tiles) generally fall under Permitted Development and do not require formal council planning permission. However, because Kew Green 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 on Lichfield Road?

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 TW9?

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 Kew completely free?

Yes. John Quilligan visits your property in TW9 in person, inspects the roof structure, loft timbers, and chimney leadwork, and provides a clear, itemized written estimate with zero call-out charges.
