The flat roof for our business was in need of repairs and Justin came out in cold winter weather to assess what repairs were needed to fix the multiple leaks.

Where this page comes from
Every figure above is Google’s, captured on 24 September 2026. The star average and the 16 ratings behind it are counted by Google across all of its reviews. The review text on this page is a sample — we hold 5, of which 5 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.
