How It Works

01

Site survey and specification

A qualified roofer inspects the existing roof, confirms structural issues, recommends materials and provides a written specification with timeline.

02

Strip out and preparation

We set up scaffold and edge protection, remove the old covering, check timbers, replace any rotten battens or felt and clear all waste to licensed facilities.

03

Re-roof and finish

Install breathable underlay, insulation and new battens, lay tiles or slates, complete flashings and ridge work, tidy the site and hand over with a 12-month guarantee.

Why Choose us for Roof Replacement & Re-roofing?

Kit and materials you can trust

We use recognised manufacturers for membranes and flashings and industry-standard scaffold and fixings to deliver long-term weatherproofing and thermal gains.

Rapid emergency support

Same-day call-outs for urgent failures limit water damage, with temporary weatherproofing followed by a scheduled permanent re-roof where required.

Experienced, accredited teams

23 years in the trade and Federation of Master Builders accreditation mean work is fully insured, managed to deadlines and backed by a 12-month guarantee.

What full re-roofing includes: removal of the old covering, inspection and replacement of any rotten decking or battens, new breathable underlay, upgraded insulation where suitable and the supply and fitting of new tiles or slates. We finish with quality lead or manufactured flashings, ridge and verge work, gutter checks and full site clearance. All waste is removed to licensed tips and a tidy handover ensures your property is left clean.

Typical jobs range from Victorian terraces in central Cambridge to modern semis and barn conversions across the fens. We plan around fragile roofs, listed building constraints and homeowner preferences for materials. Communication is clear and practical, with WhatsApp photo updates available and guaranteed completion dates from our fully insured, friendly team.

Frequently Asked Questions

Times vary with roof size, pitch and access. A typical semi can take several days once the strip-out is complete. We provide a clear schedule at estimate stage and stick to agreed completion dates wherever possible.
