Reviews

What customers say

Several recent customers praise communication and courteous crews on roofing, siding and gutter projects. One homeowner says the roof itself looked good and passed inspection but reports poor cleanup and follow-through after the job: a displaced water-heater vent became a carbon-monoxide safety concern and was fixed only after they found and reported it weeks later. The same homeowner says roofing debris remained and a kitchen range vent still vibrated after repair attempts, while calls about that remaining issue went unanswered.

Customer Reviews

Zhanna Pauluhn

We had a great experience with WestPro Roofing. Alex and Eric were diligent through a long 9-month claim process successfully turning a full insurance denial to full coverage. Once the project was scheduled, Kevin, our project manager, kept in good communication and clearly explained any issues that came up. The roofing crew was friendly and installed our complex roof in one day and made sure everything was cleaned up afterward. We’d definitely recommend WestPro!

Luke and the installation crew were fast, courteous, and professional on a complete siding and gutter replacement at my home. The team was always available to answer any questions and communicate any schedule changes, and everything turned out great. In fact, the building inspector commented on the high quality of the work that was performed.

WestPro appears to have done a good job on the roof itself. The roof looks good, passed inspection, and time will tell how it holds up. Unfortunately, the overall experience did not match the expectations set during the sales process. I was told the property would be thoroughly cleaned after the job, including nails, staples, trash, and other debris, and that WestPro took those issues seriously because of the risk to people and pets. I was also told that if something went wrong, the company was known for going above and beyond to make it right. That was not my experience. After the roofing work, several issues required repeated follow-up. Gaps in the eaves that WestPro identified as needing correction were not addressed as scheduled, and I had to escalate the issue before it was eventually fixed. Our kitchen range vent also began vibrating loudly after the work. WestPro made a couple attempts to correct it, but the issue is still not resolved. I ultimately inspected it myself and found roofing debris in the duct and fan area, including a screw, a staple, and asphalt debris. Removing that debris stopped the vibration, although the vent still allows cold air into the home. The most concerning issue was discovering weeks later that the water-heater vent had been displaced. A displaced water-heater vent is a major safety issue because it can allow carbon monoxide to enter the living space instead of venting properly outside the home. WestPro did not inspect it after the roofing work; it was only addressed after I discovered and reported it. Cleanup and follow-through were also disappointing. I raised concerns about debris left on the ground, in the grass, and on the range, but no additional cleanup was done. I ended up cleaning up much of it myself and am still finding nails, staples, and clear plastic release strips from the roofing materials around the property. This has been ongoing from mid-December until now, and after the water-heater vent was fixed, the project manager stopped returning my calls about the remaining range vent issue, which still has not been resolved. Based on my experience, the roof itself may be fine, but the cleanup, communication, safety follow-through, and post-job support fell very short of what was promised.
