Your next step
Tell us what
your roof needs.
A leak to fix or a project to plan? Start with your postcode, a callback number and a short description. We will contact you to discuss the work and what is needed for a written quotation.
Our enquiries are for roofing repairs and installations. We do not sell loose tiles, slates or roofing materials.
For a time-sensitive problem, call us to discuss it. A visit is only booked once we have confirmed it with you.
More than the visible leak
We look beyond the damp patch to check the roof covering, drainage outlets, edges and the raised sections where the roof meets walls or rooflights. Where accessible, we also check the deck: the boards supporting the roof covering. Tell us about standing water, previous repairs or water marks indoors.
Choose the scope before the finish
A local defect may be repairable when the surrounding roof remains sound. Where the covering or deck is more widely affected, replacement may be the better approach. We discuss the proposed roofing system and its detailing for your particular extension, garage or residential roof, with the scope confirmed in writing.
EPDM rubber and GRP fibreglass roofing
For EPDM rubber roofs, we assess the membrane, seams, edges and connections around walls and rooflights. For GRP fibreglass roofs, we look at the surface, trims and junctions as well as the deck where it can be inspected. Repairs depend on the existing system and its condition. For a replacement, we explain the proposed covering, deck work and drainage details before agreeing the specification.
What your flat-roof quotation covers
We set out the roof area and covering, removal of existing materials where needed, the allowance for deck repairs, edge trims, wall junctions, rainwater outlets, access and waste removal. Hidden timber damage may only become clear once the roof is opened. We explain any allowance in the quote and agree additional work with you before proceeding.
Prepare for a useful first conversation
Send your postcode, photographs taken from a safe position, an approximate roof size if known, and details of the existing covering. Include rooflights, wall junctions and drainage outlets in the photographs if they can be seen safely. We can then discuss the next step and access for a survey.

Can a flat roof leak be repaired?
Sometimes. It depends on the source of the leak and the overall condition of the roof. We assess the surrounding covering and details before recommending a local repair.
Do you work on extensions and garages?
Yes. We discuss flat roofing work for extensions, garages and residential properties as well as pitched roof repairs and replacements.
Can you quote from a photograph alone?
Photographs are a useful starting point, but they may not reveal the condition of the deck or the cause of a leak. We will explain what else is needed before confirming the scope and price.
Do you work with EPDM and GRP roofing?
Yes. We can discuss EPDM rubber and GRP fibreglass roofing for suitable projects. The selected covering and associated deck, edges and junctions are specified for the roof after assessment.
Will a damaged deck cost extra?
It depends on the scope agreed. We state the allowance for deck work in the quote and discuss any additional deterioration uncovered before agreeing further work.
Which areas do you cover for flat-roof repairs?
We work in Cheltenham, Evesham, Gloucester, Tewkesbury, Cirencester, Broadway, Pershore and surrounding areas. Send your full postcode so we can confirm coverage and arrange the next step. For an active leak, call to discuss current availability.
Can I choose an insurance-backed guarantee?
Yes. Britannia Roofing offers an optional insurance-backed guarantee (IBG) with eligible roofing work. Ask us to confirm the available cover, any additional cost and the policy terms with your written quotation. It is not automatically included with every job.
