We would recommend using any other supplier than daystar. After the job was done we by accident found out through another contractor several things they did incorrectly such as leaving holes in the roof where they had drilled and not sealed . We called to complain about this in order to have it fixed and we were met by a barrage of profanity that we cannot repeat here. If that is their method of conducting customer service they won t be around much longer. Strongly suggest using other companies there are several on line .
