What Our Clients Are Saying

"We would rarely, if ever, give full marks for a score on anything. However with the Rooftop team we couldn't find fault (I did try!). This was a large project which meant us moving out however everything was done timely to get us back into the property. From the moment Craig and Ryan came round to discuss our plans, to providing the quotation, to completion, the team have been really hard working and nothing but professional. The quality of the finished product is first class. They are very thorough, transparent with pricing and friendly. We are very impressed and would highly recommend them."
