Roofing help across Chelsea, including SW3 and SW10

Avent undertakes roof repairs, replacements and detailed paid surveys for Chelsea properties. If water is entering now, call our 24/7 emergency line to discuss the immediate problem, attendance and charges.

For planned work, send the full postcode and which roof is involved. A main pitched roof, rear extension and terrace can need different investigations and specifications.

Flat-roof and roof terrace leak repairs

The location of an internal stain is a starting point, rather than a diagnosis. We consider the waterproofing, drainage, upstands and junction with the building. Previous repairs and photographs can help explain how the problem developed.

Liquid waterproofing may be suitable for a flat-roof renewal, depending on the existing construction and chosen system. A local repair may be appropriate where the defect is isolated; wider deterioration can require a different scope. Our Hampstead terrace project shows preparation, waterproofing and the finished surface, with its actual location clearly identified.

Slate and tiled-roof repairs and replacements

Rear access, shared corridors and rooms below the work all matter when setting out a roofing job. Tell us about occupied areas, delivery restrictions and any other refurbishment planned for the property.

We repair and replace slate and tiled roofs, including the associated ridge, valley and chimney flashing details. We consider the affected area and surrounding condition before proposing a repair or renewal. The written quotation explains the proposed scope and access, so you can review what is included before proceeding. Our roofing quotation checklist helps you compare what is included.

Roof surveys before buying or planning repairs

If you need a documented assessment rather than a price for works, request a separate paid roof survey. Photographs, written findings and repair priorities can help you understand the accessible roof before buying or deciding what to do next.

Send the postcode of the property being surveyed, even if you live elsewhere, and any concerns or purchase deadline. The inspection scope and fee are agreed before booking.

Common questions about roofing in Chelsea

Answers to common questions about the next step.

Do you take on smaller roof repairs in Chelsea?

Yes. We assess local repairs and smaller roof areas as well as full renewals. The required detail, surrounding condition and safe access all affect the quotation.

Can you investigate a leak that keeps coming back?

Yes. Tell us when it appears and what earlier repairs involved. We assess the roof and connected details before explaining the proposed next step; concealed defects may need further investigation.

Can work be planned where access is through the house?

Tell us the available access route, shared areas and occupied rooms. We will discuss the practical arrangements needed for assessment and the proposed work before agreeing the scope.

Is a roof survey included in a free quote?

A free roofing quotation prices proposed work. A detailed roof inspection and written condition report are a separate paid service, with the scope and fee agreed before booking.
