One week after the completion of the new roof, we contacted Johnson Irrigation for an estimate on a whole roof drainage system. The price was reasonable and we decided to go on with the job. It took two days and the staff was very professional. The whole drainage system was installed around the roof. Three gutters were installed for better irrigation : one to the driveway, one to the side of the house and one small one to the backyard far from the house. The whole system was tested during one day of rain and the drainage system was very efficient. Great job by the company.
