Everything went smoothly from sales to installation. Installing a metal roof was more expensive than most other materials, but it’s going to last 40 years+ and the warrantee can be transferred to the next owner. We’re not handy and this is a huge peace of mind. We loved that this company does not subcontract and actually trains its crews on how to exclusively use their system of interlocking roof tiles. Because of this, the crew gets to work straight away, knows what their doing, and finish quickly. The things that took the longest to install were the skylights because they had to be custom made. That said, they placed a sufficient cover over the holes on the roof that held up to rain and tree debris. Interlock was easy to work with and we love the results!
