Highlights
"Highly recommend this company! Really helped us out recently. After getting a quote from another company, which we thought was extortionate! Jamie come round and sorted the issue with a very reasonable quote and got the issue sorted the next day for us. If you want a genuine Roofer who isn’t out to rip off their customers, Jamie is your man!"
"James was reliable, prompt and did a very good job fixing the bay roof and fascia. Highly recommended."
"I find JM Roofing to be very reliable, providing realistic quotes and a highly professional finish, with excellent quality. This is the second time I have used them and have also recommended them to other family members and friends."

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.
