Should have reviewed a couple years ago. But here we are today. They installed a Metal roof for me at a very reasonable price and did an excellent job. There were a few snafus, but every time Marcel handled it like a professional. And has been quick to respond post completion to any issues or questions that I had.

This air duct cleaner did the job at half the rate other companies were quoting. If you are on a shoe-string budget, use these folks.♥️

Where this page comes from
Every figure above is Google’s, captured on 24 September 2026. The star average and the 10 ratings behind it are counted by Google across all of its reviews. The review text on this page is a sample — we hold 10, of which 8 have any text — and it is not everything Google shows.
Roof Warden does not verify licenses, bonds, insurance or workers’ compensation cover, and nothing on this page should be read as though we had. Confirm those directly with the contractor and with your state or provincial licensing body before you hire anyone.
There is not much data on Sierra Pacific Roofing. A short record here means our capture found little — not that there is nothing to find, and not that the business is new or inactive.
