Highlights
"We contacted Mark Douglas Roofing in respect of their flat roofing work. The work we required involved two flat roofs that we have, one on a garage, the other a flat roofed extension at the back of our bungalow. Following the awful weather we had at the back end of last year and the even worse weather in early 2026 we noticed a damp patch on the inside of the garage roof which in one case started to drip onto the floor. Mark visited and gave us a quote for repairs which we accepted and then completed the work required in 2 days with no mess or fuss leaving us completely satisfied,"
"Mark carried out a flat felt roof over an asbestos garage roof. It saved us a lot of money by not having the asbestos roof taken away. He reinforced the roof struts, boarded over the asbestos roof and laid a felt roof on top. The men worked tidily and efficiently, and the price was reasonable. I would not hesitate to recommend Mark, and his team, for a very professional job. Hazel Haselip"
"From the initial contact to assess the damage to the flat roof of my house, through providing a detailed quote to completing the work to a high standard, the team were prompt, polite, reliable and totally professional. They thoroughly tidied at the end of each days work being respectful of my property. I would thoroughly recommend this company and should I have further need for a roofing company for example my garage, I would not hesitate to contact Mark Douglas and the company."

Smart checks
Before you hire an architect
Only someone on the Architects Registration Board (ARB) register may legally call themselves an 'architect' in the UK — ask for their ARB number and check it free at arb.org.uk. An 'architectural designer' or 'technologist' is a different, unregistered role (often capable, but not the same protection).
Agree how they charge before any work starts — a percentage of the build cost, a fixed fee, or an hourly rate — and exactly which stages it covers (concept design, planning application, building-regulations drawings, work on site), so there are no surprises later.
Confirm what they will actually handle versus what is excluded — the planning application, the building-control drawings, and whether they will administer the builder's contract on site — and get it, and a portfolio of similar projects, in writing.
Ask to see a portfolio of completed work like yours, plus recent references you can contact.
Check the credentials and registrations that matter for this work — and that they are current.
