Portsmouth's coastal environment creates a specific new build roofing brief that differs from inland Hampshire projects. The specification decisions made at new build stage — fixing type, underlay, tile selection, lead code, ventilation provision — have consequences that play out over the 40–60 year design life of the roof. Getting them right costs a modest premium; getting them wrong creates a roof that underperforms from day one in a demanding environment.
We have carried out new build roofing across residential developments, extensions and self-build projects in Portsmouth for over 20 years. We understand the programme pressures that contractors face — we deliver to programme, provide all required documentation, and carry out our work without creating delays to other trades on site.
Our standard Portsmouth new build specification: BS5534-compliant installation, breathable membrane underlay, 25mm pressure-treated counter battens, 50x25mm pressure-treated tile battens, marine-grade A2 stainless steel fixings throughout, mechanically fixed ridge and hip tiles, correct ventilation provision at eaves and ridge. Lead flashings at all abutments and penetrations to the correct code for the exposure position.
We advise on tile selection based on the project's exposure position, planning requirements and programme. Portsmouth planning requirements for conservation area sites may specify particular materials — we identify these early. For standard residential positions we recommend modern concrete interlocking or clay tiles with a 30+ year product guarantee.
We provide: NFRC membership confirmation, installation specification, product data sheets, fixing specification, workmanship guarantee certificate, and staged inspection sign-off at felt/batten and tile stages for building control purposes.
