Roof repairs, replacements and flat-roof waterproofing for Chelsea homes, extensions and terraces in SW3 and SW10. Tell us about your roof and request a free written quotation from our NFRC-member team.
Free roofing quotations. Formal roof surveys are a separate paid service.

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.
Explore roof 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.
Explore flat roofing and terrace waterproofing ↗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.
Find out about roof replacements ↗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.
