We have purchase EPDM rubber roof from this company. Have sent the technical drawings over and agree on having 2 pieces as our summer house is an L shape, they have got the measurements wrong and sent us an additional strip to patch it up. The additional strip was too small as well, and they sent another one. All in total 4 different seams now, this took hours spent on the phone waiting to speak to someone, a lot of going around the tail, in the end they refused to refund us or send the correct pieces. We ended up with 4 different pieces on our roof. EXTREMELY DISSAPOITING EXPERIENCE. PLEASE GO FOR OTHER COMPANY, I WISH WE WOULD VE READ THE REVIEWS BEFORE WE PLACED THE ORDER.
