If you are looking to have water problems where you never had them before, ice forming all winter from no ventilation in the soffits, poorly sloped, leaking troughs . . .THESE ARE YOUR GUYS!!! These “new” troughs are just over a year old and the whole mess has to be replaced. At our cost. Not to mention the damage to the basement from the water and ice backing up and finding its way into the walls, or the roof repairs we’ll have to do to fix the damage from heat being trapped (no vents installed under the soffit) and the wood warping. If I can save 1 person from the problems we encountered since dealing with Blackstar Aluminum, this review will be worth it. While the head guy, Pat, is a personable fellow, he’s not the one who does the work. But he is the one you will be arguing with to try and get things done right. Do yourself a favour – find a company (any other company!) that installs seamless troughs . . . . and save the grief and damage to your home. I wish we had.
