New analysis of 921 local enquiries reveals asbestos concerns, garage dimensions and roofing patterns across Manchester’s M postcode area.
BOLTON, UK. November 12th, 2026 – Nearly three in four garage roof enquiries received by Danmarque from Manchester’s M postcode area explicitly referenced asbestos, according to newly published research examining garage roof concerns and characteristics reported by local homeowners.
The garage refurbishment specialist analysed 921 enquiries from the M postcode area, received between April 2020 and September 2026. Of these, 674 explicitly mentioned asbestos, representing 73.2% of the local sample.
The findings form part of Danmarque’s interactive UK Garage Roof Data Explorer, which allows homeowners, journalists and property professionals to investigate garage roof enquiry patterns across different parts of the country.
The research reveals that asbestos was mentioned in a substantial proportion of Manchester enquiries, although the local figure was below the 77.4% recorded across Danmarque’s complete dataset.
The difference of 4.2 percentage points highlights how the characteristics of enquiries received by Danmarque vary between locations.
Alongside asbestos references, the Manchester research provides an insight into the types and dimensions of garage roofs represented in local enquiries.
The typical recorded garage dimensions were 5.7 metres by 2.9 metres. Single garages accounted for 88.3% of classified enquiries, while double garages represented 6.9%.
Flat roofs accounted for 54.7% of the local sample, compared with 64.1% across the complete dataset. Pitched roofs represented 36.3% of Manchester enquiries, compared with 29.0% nationally within Danmarque’s records.
These differences offer a picture of the garage roof characteristics reported by homeowners contacting the company, rather than a representative survey of Manchester’s entire garage stock.
Asbestos-containing materials were historically used in garage roofing, including asbestos cement sheets, before the UK’s prohibition on asbestos use came into force.
The findings highlight the importance of understanding the materials present in older garage roofs, particularly when homeowners are considering maintenance, refurbishment or replacement.
However, an asbestos reference in an enquiry does not mean asbestos has been professionally identified or confirmed. The research cannot establish how many garages across Manchester contain asbestos.
Danmarque is a UK garage refurbishment specialist providing garage roof replacement, asbestos garage roof replacement and wider garage refurbishment services.
The company works with homeowners across England, Scotland and Wales and publishes research and practical information to help property owners understand garage roofing materials, maintenance and replacement options.
Cullen Evans, Head of Marketing & Finance at Danmarque, said: “Few people see as many garage roofs as we do, and this research draws on thousands of real enquiries to show what homeowners in Manchester are dealing with.
“It isn’t a survey of every garage, and a mention of asbestos isn’t a confirmed finding. However, what it does show is how often asbestos comes up as a concern locally, and how Manchester compares with the rest of the country.
“We hope it helps people recognise that their own garage roof could contain asbestos, and encourages anyone who suspects it to leave it undisturbed and have it safely removed and replaced by a professional.”
Homeowners concerned about suspected asbestos-containing roofing materials should avoid disturbing them and seek appropriate professional advice before undertaking work.
The Manchester findings are available through Danmarque’s interactive research tool, where visitors can examine local figures, compare supported postcode areas and download charts illustrating the results. The company have also created an interactive national research tool.
