Don't waste your time. Had them out for an estimate for a job, never heard anything. Called back a week later and was told my estimate will be ready by the end of the week. Nothing. Called back 3 more times over the next few weeks, and each time was given the runaround. "Oh let me look into that for you and we'll get back to you". If you're looking to waste your time, this is the company for you. If you're looking for a roofing project to get completed, better call someone else.

I was skeptical at first and had large ice dams and a lot of leaking going on in my home. This company came out the next day and cleared a lot of ice and snow off the roofs. There was no damage to my roof and it was very fairly priced I …

Outstanding customer service! I was in a panic over the ice, snow and icicles on my mothers roof after the latest big storm. I left a message over the weekend. The office followed up when they opened Monday morning and had their folks out to clear everything that very afternoon! Thank you soooo much!

After a severe storm that badly damaged my home’s roof, I sought a reliable company to address the issue. On Top Roofing, led by owner Tim, exceeded my expectations with their deep knowledge of roofing services, turning a stressful situation into a smooth, educational, and reassuring process. From the first contact, the professionalism and expertise of the team, reflecting Tim’s vision, were evident. They explained in detail what needed to be done, from assessing the damage to the options for materials and repair techniques. It wasn’t a “quick sale” approach; it was a genuine transfer of knowledge, as if I were learning alongside them. This transparency made me feel extremely comfortable and confident that I was making the best decision for my family. During the execution of the work, On Top Roofing demonstrated impeccable professionalism. The team, coordinated by project manager Jefferson, was punctual, organized, and respectful, always keeping the site clean and safe. Jefferson collaborated with me at every step, patiently answering my questions and ensuring I felt part of the process. It didn’t feel like a mere business transaction but rather the building of a relationship based on trust and care. The final result was a roof not only repaired but reinforced with superior quality, providing long-lasting security for my family. Knowing we are protected against future storms gives me invaluable peace of mind. On Top Roofing didn’t just fix my roof; they provided me with confidence and tranquility. I wholeheartedly recommend On Top Roofing to anyone seeking not only excellent service but a genuine partnership. Thank you, Tim, Jefferson, and the entire On Top Roofing team, for turning a challenging moment into such a positive experience and for ensuring my family’s well-being for many years to come! Sincerely, Alex

Where this page comes from
Every figure above is Google’s, captured on 24 September 2026. The star average and the 114 ratings behind it are counted by Google across all of its reviews. The review text on this page is a sample — we hold 30, of which 26 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.
