 Trustindex verifies that the original source of the review is Google. I engaged Proactive to replace a flat roof for me after being expensively let down mid-job by another 'firm'.  To say that Proactive are highly professional would be to understate the matter - they are simply excellent.  An initial survey, followed by a technical survey led to the production of the time and materials schedule and all associated documentation.  All costs were itemised up-front and a price for the whole job agreed.  I had my own (attractive and intelligent) project manager allocated and she kept things on track and kept me informed.  Everything was properly co-ordinated, including materials delivery, skips and scaffolding - thanks, Becky.  The guys who did the work, Jake and Rocco, were first-rate and fun to have around as well as working like beavers on some of the hottest days of the year. Once the job was done it was re-inspected by the relevant managers for any snagging issues before being signed off.  The guarantee is first-rate, and I have a client folder with dozens of photos showing the work progression at the end of each day. Overall, I could not be happier with this.  Well done, PRF.

 Trustindex verifies that the original source of the review is Google. Having been let down badly with poor workmanship. I contacted Proactive Flat Roofing After a very thorough survey of my roof by Mr Stephen Day, it was decided that the only option I had was to get the roof redone. After getting another report from an independent surveyor who also condemned the roof as not fit for purpose. I accepted the very concise written quote from Proactive Flat Roofing.I also received a very good guide booklet explaining  in detail  their product and their guidance to getting your roof done. From the first site visit by Mr Stephen Day and then to the great communicational and organisational skills of the support team Becky,Cloe,Yvonne,Charlotte,and Carla. To the Skill and Professionalism of Dave the Roofing Technician. I genuinely believe that I could not have contracted a more dedicated to customer satisfaction driven team of people. If you are getting your flat roof done, do not go down the route I did by NOT checking the roofing businesses certification and accreditation certificates. To get a "Proper Job" done Think about giving PROACTIVE FLAT ROOFING A CALL

 Trustindex verifies that the original source of the review is Google. The team are highly professional. Paull helped us sort a roof on a house we had recently purchased that had some major construction flaws. Communication from the start was outstanding. Every member of staff we dealt with were very knowledgable and answered all our questions. Would certainly recommend, quality work.

 Trustindex verifies that the original source of the review is Google. A very professional organisation that attended site at agreed times to investigate our fault and came up with the required solution. The operatives were polite and friendly and kept us constantly informed of their progress. They kept disruption to a minimum and tidied up after them selves. A pleasure to deal with and would highly recommend.

 Trustindex verifies that the original source of the review is Google. Proactive Flat Roofing fixed a major roof leaking problem. Their product and professional services far outweighed other companies I researched. Camaron and Ryan worked tirelessly to complete the job and I am highly satisfied with the outcome.

 Trustindex verifies that the original source of the review is Google. Proactive Flat Roofing undertook a roof refurbishment project that I was overseeing in Battersea.  They were extremely professional, co-operative and adaptable (we had a few obstacles to overcome due to difficult tenants) and their workmanship was excellent.  Overall very pleased and wouldn't hesitate to recommend them on any future suitable projects

What Customers Say

"In simple terms, Stephen knows his stuff!"

Recently I built five, four-bedroom homes in Surrey. While I’m experienced with refurbishing and extending properties, this was my first new build project, and the first time I had to meet standards set by the company that issues the building warranty. When I reached out for help with the flat roofs, I was looking for someone who understood what I was up against, and who could inspire confidence. Stephen was the first person to get back to me showing the right kind interest.

I’d spoken to others; I just wasn’t getting what I needed in terms of advice. So I was happy when I found someone on the phone that seemed friendly, straight talking and well informed. I liked him right away. I had a thousand and one questions for Stephen, and I particularly want to thank him for his patience. The building was nearly at roof level when I called him in. I needed lots of answers, and I needed them fast. When I described my issues to him on the phone, he instantly knew what I was talking about. And if there was ever a time that he didn’t know straight away he’d find out and get back to me. So his responsiveness impressed me.

Just to give you an example, I had my carpenters laying the wooden roof deck ready to hand over, when questions came up about the ventilation system. I was under pressure to get the roof on, and while it’s easy reading the book about the standard required for the warranty, it’s not one hundred percent clear. In this kind of situation you know he’s got the answers. “Don’t do it like that, this is how it needs to be done. Put this in, don’t do that. Simple.”

Stephen is extremely professional, very helpful. He’s well informed of his facts and he knows what he’s talking about. To put it in its simplest terms, he knows his stuff.

"Paul has done numerous new build and replacement flat roofs for me. Everybody walks away happy."

I own a building company in the Cotswolds, established in 1881. We do the typical work of general builders, including house extensions and refurbishments. In the nine years or so that I’ve known Paull he’s done numerous flat roofs for us. We have a really good working relationship and have always been really satisfied with his service.

He’s always coming up with things. What I mean is if you’ve got a problem, even if you think you know how to sort it out, he’ll normally find a better way to do it. Needless to say I don’t go to anybody else apart from Paull for flat roofing. Because I know that when he does it, it’ll be done right and everybody walks away happy.
