Approved expertise. A system chosen for your roof.

Avent is a MonoSeal approved applicator and a Tecnopol approved contractor for Desmopol flat roofing systems. We will explain the proposed system, preparation and finishing details as part of your quotation.

Your questions

A little clarity, before you decide.

If you have a specific concern about your roof, tell us when you enquire.

Are roofing quotations free?

Yes. Quotations for roofing work are free. Tell us about your roof and postcode so we can discuss the assessment needed. A formal roof survey or condition report is a separate paid service; emergency attendance or specialist investigation may also carry an agreed charge.

Can you help with a small repair as well as a new roof?

Yes. We handle roof repairs and complete replacements. We assess the defect and explain whether a local repair is appropriate or whether the wider roof needs attention.

Do you cover Finchley, Barnet and Hampstead?

Yes. These are part of our North London coverage, alongside Highgate, Muswell Hill, Primrose Hill and St John’s Wood. We also cover Central London and nearby areas including Kensington and Chelsea. Send your full postcode to discuss availability.

What happens if my roof is leaking now?

Call us with your postcode and a description of the leak. We will discuss urgency, access, availability and any attendance charge. An online enquiry does not reserve an emergency visit.

Which flat roof systems do you work with?

We work with liquid waterproofing, including MonoSeal and Tecnopol Desmopol, and discuss other suitable flat roof options for the property. We are a MonoSeal approved applicator. The quotation identifies the actual system and any applicable warranty.

Can you provide a report for a house purchase?

Yes. We offer pre-purchase and roof condition surveys as separate paid services. Tell us why the report is needed and any deadline so we can agree its scope and fee.
