  Metal Roofing Merrimack, NH Review

  Review: December 30, 2022Completion: April 27, 2022

  We love the stylish new look our house got with the Metal Slate Roofing and the longevity Interlock Roof System offers. Although the roof is made of aluminum, the design makes the roof look as if it was traditional slated roof.

  Metal Roofing Merrimack, NH Review

  Review: February 22, 2017Completion: November 30, 2016

  Interlock installers were great to deal with. They completed the job in half the time that was quoted. The one minor discrepancy I found two months after installation was fixed by an Interlock representative less than twelve hours after reporting it. The higher cost of an interlock roof has been worth every penny and I’m not even through my first winter yet.
