I strongly recommend against using this company for roofing your house. My brand new home was built in 2019 and the roof leaked during construction. It leaked the year after Construction and again the year after. They kept coming up with excuses even had us install heat tape on the home to prevent the leakage which just caused it to leak more. They then had their attorney send me the homeowner a letter saying that it is not the roof that is leaking in the water is coming from somewhere else well this is not true the roof is leaking I've had three other roofers up that have said that it is the wrong material. I suppose I will have to bring up a lawsuit. Update August 2022: Well I would have loved to update this to say that Frontier Roofing has made good on the roof. Unfortunately, they just passed me on to their insurance company which has been no help after months of correspondence. We have given them every opportunity possible to make this right. Unfortunately because I need a roof for winter I had to have somebody else do it. Upon inspection it was found that the roof was installed improperly with screw holes through many of the seams penetrating the membrane underneath. Some of Them Crooked or with heads missing. No caulking on the flashing. So they use the wrong material and installed it improperly, took my money and destroyed my house on the inside over the course of 3 years of denying there was a problem!

*update Nov 2022. Frontier still is unwilling to make good on all their mistakes. I am now part of a legal dispute in which is costing me even more money and wasting even more time for everyone die to thier incompetence.

*update May 2023. Frontier still not owning up to thier shoddy work. Still involved in dispute.
