"The work that was carried out was replacing a flat roof. Philip spoke to my other trader who was in at the moment to make sure everything fit perfectly. Great value for money. Philip was always on hand to ask anything."

"My approx. 5m x 6m kitchen extension was completed with a fibre glass warm roofing system. The roof was boarded, vapour barrier fitted, insulation applied, top board fitted, fibre glass system applied. The roof was a flat roof with a large glassed lantern which had been installed by others. The survey was carried out by a helpful considerate surveyor who listened to my requirements he also gave his knowledge. I received my quotation in a good time, the quote was clear and a fair price. The install was carried out at the agreed date by a team of professional roofers who were courteous and hard working. The finished job is of a good standard and the up stand around the lantern was applied with skill as no residue is present on the glass. The finished job looks great."

I saw Fibrespan at a trade show earlier this year and was taken by their professional approach to flat roofing. I was very interested as my mother was looking to replace her extention roof as it was very old and started to leake. A few days later Philip came over and surveyed the roof. I was expecting to get the hard sell treatment but instead he went away and worked out a very reasonable quote for us. When the fitters had finished we were blown away by the amazing quality of the finish and how professional and helpful the fitters were. We are so glad we chose Fibrespan. A big thanks to Philip and all his team. We definitely recomend them and will tell all our friends. Five stars ⭐

Fibrespan were excellent from start to finish. Professional, efficient and friendly service. Roof and skylight installed are wonderful. Workers were very nice, tidy and considerate to the neighbours and us. Estimate given 9 months previously was honoured and we did not even have to pay a deposit. Cannot recommend them highly enough, but would say they are not surprisingly in high demand, so book up long before you need the work done!

Before you hire a builder

Never pay a large deposit up front — agree a staged payment schedule tied to completed milestones, and hold a small retention until snagging is done.
Get it in writing: an itemised quote with scope, materials, start and finish dates, and how any changes (variations) will be priced.
Be wary of a cash-only price or pressure to start tomorrow — both are red flags for an unaccountable job.
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.
