Roof repairs, flat-roof renewals and pitched-roof replacements for Westminster homes, flats and managed buildings. Request a free written quotation, or discuss a separate paid condition survey before planning work.
Free roofing quotations. Formal roof surveys are a separate paid service.

We welcome roofing enquiries across Westminster and the SW1 area. Tell us the complete postcode, what the roof serves and whether the priority is a leak, a planned replacement or a condition report.
Avent works on slate, tiled and flat roofs. For an active problem, call our emergency roofing line, answered 24/7, to discuss attendance and charges. For planned work, a written quotation sets out the proposed scope. Include existing photographs, relevant reports and a brief history of previous repairs when enquiring.
Explore roof repairs ↗Where several flats or occupiers are involved, identify the person who can authorise the assessment and arrange access. Useful information includes the affected rooms, roof hatches, previous repairs and any existing report.
A paid survey can provide a documented view of the accessible roof and its defects before a programme of work is chosen. We agree the inspection scope and fee, explain limitations and provide photographs, written findings and repair priorities. View a genuine anonymised report extract to see how findings are presented. For subsequent works, see our commercial and managed-building roofing service.
Explore roof condition surveys ↗Outlets, upstands, rooflights and service penetrations should be considered alongside the roof surface. Tell us about rooftop equipment, occupied areas and any hours when access is restricted.
We assess the existing roof before proposing a repair, suitable overlay or fuller renewal. For renewal work, we discuss the specification, access and proposed sequence before a start date is agreed. Our Leyton block project shows a roof before and after liquid waterproofing, recorded from above; this example is from our wider London work. Explore our flat roofing service for more about repairs and renewals.
See the block roof renewal ↗For slate and tiled roofs, the condition of the covering and details around ridges, valleys and chimneys helps determine the appropriate work. An isolated defect may call for a local repair; wider deterioration needs to be considered before committing to repeated patching.
Tell us which roof slopes or rooms are affected and share any existing report. A replacement quotation should define the proposed covering, associated details and access. Our quotation checklist helps you compare the scope.
Explore roof replacements ↗The documented Leyton block renewal and tiled-roof portfolio show examples of our work elsewhere in London.

Yes. Send the address, existing findings and the contact who can arrange access. We can discuss whether the next step is a quotation, a formal condition survey or further investigation.
Access and concealed construction can limit what an inspection establishes. We explain the agreed scope and record limitations, including where further investigation is needed.
The proposed access forms part of defining the work. Tell us about shared entrances, roof hatches and restrictions so these can be considered alongside materials and roof details.
Yes. We work on individual properties as well as larger roofs. Tell us what needs attention and whether you want a roofing quotation or a separate paid survey.
