I live in a block of flats in North London. For 10+ plus years we have been beholden to a management company (investigated by the Sunday Times this year) who have covered our building with Acropol whilst putting our service charge through the roof. Having now got rid of them and their associated cowboys we are delighted (having met with 19 roofing companies - all with different solutions and prices) at the success of the flat roof liquid solution provided by MJO Roofing. Mark the owner is very courteous, professional and reliable. Paul and Jimmy who did the job were beyond reproach. They showed up on time, left the site spotless each day, were happy to answer questions and most importantly did an excellent job. My flat has leaked since 1999 and they fixed it! Have recommended them to many other Which? trades, family and neighbours. Happy for future customers to contact me through MJO - if that would assist and avoid years of stress as it is exceptionally hard to identify 5 star roofers and know who to trust. A very confident recommendation. Thanks again guys!! Superb job.
