International Exteriors, LTD looks great on the outside but leakes like a sive inside SCAMED!!!!! dartmouth, Nova Scotia

I am disappointed in this roofing system and the lack of service with this so called warranty ... this roof has leaked in several places and the installers ( Inter Exteriors 902 468 2223 ) refuse to even return several calls after stating in feb they would come and asses this mess , its now almost may  ... I have water damage too which ill be contacting my insurance company due to this junk they installed on my roof .... I will be relentless in showing the pictures of the damage to my home and exposing these crooks who call themselves installers ... not to mention a civil suite if possible
