John gave a First Class service from start to finish. His knowledge and advice was outstanding and his craftsmanship and pride in his work was exceptional. Nothing was too much trouble and I would not hesitate to recommend him highly to anyone looking for a fibreglass flat roof. More...

John did a great job for us, great communication, very thorough and knowledgeable about his business. Would highly recommend - did our flat roof nearly a year ago now and it still looks as good as when he put it on.

1st class service, knowledge and advice has served me brilliantly in other aspects, top job. Don’t do a fibreglass job without chatting and getting a quote from John (the fibreglass specialist) first.

I contacted John from the internet who then visited my property and prepared an estimate for my carport roof. His knowledge about the aspects of the work was very reassuring. The works were carried out in a very professional manner and i would highly recommend JJ Keane. More...

Excellent service from beginning to end. John came to replace a very poor condition (leaky) Polycarb roof and all of the roof timbers. Very professional job and communicated regularly as to when he would likely arrive to do the job, (weather dependent). Took 3 days solid work and he pulled in 12-13 hour shifts. I found him to be polite and approachable and he even gave advice on finding a suitable skylight. Would absolutely use again and thoroughly recommend. Great job, very satisfied customer! More...

John Keane (found via Google) was one of three companies I asked to quote for two flat roof replacements- small kitchen extension and a bedroom- on my bungalow.
He was friendly and business-like and explained in detail the process and the type of material to be used. He also offered references without prompting one of which was within a mile of my home.
I accepted his written quotation (received by e-mail) and the work was completed over three days (note the time it took: not a rushed job). Viewing the partly completed job in the evening I could appreciate the workmanship and degree of care taken. The finished job looked clean and smooth in a neutral grey colour.
I am happy to recommend John Keane but should add that I have no connection with his business other than as a satisfied customer.
