How It Works

01

Site Survey & Options

A measured survey assesses roof structure, insulation and ventilation needs. We advise on placement, glazing types and whether planning or building control advice is needed.

02

Design & Quotation

We produce a clear specification showing materials, flashing details and how the upgrade will match existing tiles or slates. You get lead times and a written guarantee before work starts.

03

Installation & Handover

Work is completed by experienced roofers using manufacturer components and lead flashing where required. We finish with a site clean, a final inspection and the issued 12-month guarantee.

Roof features that work for homes in Cambridge and the Fens. We install rooflights, skylights, dormers and mechanical ventilation to suit period cottages, modern builds and loft conversions. Each component is chosen for durability and thermal performance, then integrated so the new feature sits visually and structurally with your existing tile or slate roof.

Technical fit matters. That means correct flashing, upstands and insulation continuity to prevent leaks and condensation. For heritage properties we match slate types and tile profiles. We also carry out leak detection and roof surveys if older fabric needs attention before new openings are formed.

Frequently Asked Questions

Many skylights and modest rooflights fall under permitted development, but larger dormers can require planning permission, especially on period properties or in conservation areas. We advise at survey stage and can outline when to consult your local planning authority or building control.
