Very pleased with this work!

Overview have replaced the roof of my garage and porch and have fitted new ceilings. I'm delighted with the quality of their work. They were courteous, prompt, arriving at the times agreed, end they left the inside of my garage tidier than it was before. All other bits and pieces from the work were cleared away and the floors swept. I can definitely recommend them!

Replaced garage roof

Attended at time agreed time to give an estimate. Quickly gave the estimate, very good communication via text and email keeping me informed of their attendance once I had accepted their estimate. The team who attended were very knowledgeable and hard working. They removed the rotten roof on the garage and replaced it within a day. They returned the following day to complete some work on the pitched roof of bungalow. A further issue was found and they came up with a solution. All rubbish removed. All completed at the very fair initial estimate.

To be highly recommended. polite, reliable, punctual. Wasted no time in getting the work finished. Took care as to not damage surrounding tiles. Left no mess, swept and cleaned the work area and surrounding house front pathway. Jordan is an excellent roofer, good communication with him throughout the work.

Top job

Josh and his team were very professional. He delivered both on the timeframe and within Budget. The work was delivered to the highest standard and attention to detail and the consultation process throughout was very clear and timely. The work involved wasn’t as straightforward as most roof replacements as it involved the removal of spray foam insulation. This was removed and disposed of successfully with minimum disruption and impact. Josh coordinated his team well from arrangement of scaffolding, adequate skip hire, removal and disposal, appointed craftsmen for velux windows and lead work .
