Marj Kokko review about company Interlock Industries, Inc.

On 6/1/18 our Interlock roof was completed. From the start of the job to the finished product, everything went smoothly. Glen Boss explained every detail of the project to us in easily understood language. Angela kept us informed of the details of arrival of materials & start of work. The crew arrived on time, & did their job efficiently & with excellent attitudes. They cleaned the area each day before they left. We choose the black aluminum that looks like slate. The roof is beautiful, & neighbors & passers by have given us many positive comments. We highly recommend this company & their product.
