NO.. NO do not use them! They put a new roof on my house several months ago and yesterday we had our first rain. It poured into the living room and ruined our new ceiling. Jack (owner) came by last night and didn't fix it, he said it looked fine up there (pouring water into the house didn't seem to mean there is a problem to him and he didn't even cover the leak with a tarp). He didn't return calls today, and is taking no responsibility at this point. Long story short it turns out Jack didn't get a permit for the roof, either. I will take this review down after Jack fixes his bad job and pays my drywall man for the repairs. Also, when Jack was putting the roof on, his worker fell through the ceiling, breaking the toilet. I let that one go. Now no, he's going to need to fix that, as well.
