Our office address is 11 Old Bond Street, Mayfair. We take roofing enquiries across the area, including W1K and W1J, and arrange assessments at the property. Call or send the full postcode and details of the work you have in mind.
An active leak, an upcoming refurbishment and a longer-term renewal programme each need a different starting point. We discuss the roof areas and existing information before defining the work.

Tell us which roof needs attention: a rear extension, roof terrace or larger roof serving a managed building. Describe any leaks, the existing covering if known, and details around rooflights, outlets or equipment.
We assess the roof before proposing a local repair or renewal. If liquid waterproofing is being considered, the existing roof and surrounding details need to suit the proposed system. We are approved applicators for Tecnopol and MonoSeal systems; the specification is agreed for the particular roof.

Balcony renewal with an anti-slip finish
Water ingress from this Mayfair balcony was affecting the office space below. Avent renewed the balcony and added an anti-slip finish.
A leaking balcony or terrace can affect the rooms underneath. Tell us where water is appearing and how the outside area is used. We’ll discuss an assessment before recommending repairs or renewal and providing a written quotation.
Get useful condition information before major work
A detailed roof survey can help an owner or managing team understand the roof’s condition before requesting work quotations. We use internal and external checks, drone imagery and moisture readings where suitable, with access and limitations explained in the report.
Share any existing specification, previous report or purchase deadline. The survey scope and fee are agreed separately from roofing works, so you know what is being commissioned.
Explore detailed roof reports ↗A specification that reflects the building
Rooflights, equipment, service penetrations and drainage need attention alongside a new waterproof covering. Let us know about equipment that must remain operational and any contractors involved in the refurbishment.
For planned renewals, the quotation identifies the roof areas, proposed materials, associated details and access. Insurance-backed guarantees are available for eligible work; applicable cover and terms must be confirmed for the agreed specification.

Answers to common questions about the next step.
What should I send for a roofing quotation in Mayfair?
Send the property postcode, the roof area involved and a brief description of the problem or proposed work. Photographs, existing reports and details of access or building-management arrangements help us discuss the next step. Roofing quotations are free; a formal inspection and written condition report is a separate paid service.
Do you handle both residential and commercial roofing enquiries?
Yes. Share the building details, roof information and any specification. We will discuss the assessment, access and operational needs of the proposed work.
Does booking a survey commit me to Avent for the works?
No. The roof survey is a separate paid service. Avent also carries out roofing, but you can obtain other contractors’ quotations for any recommended work.
Can you work from an existing roof report?
Send the relevant report or proposed specification when you enquire. We may need to assess the roof and access before confirming the work we can quote for.
Can I call about a roof leak outside office hours?
Yes. Emergency calls are answered 24/7. Attendance, availability and charges are discussed on the call; an online enquiry does not book a visit.
