What is going on here? No, this roof does not have measles, it has a problem with thermal bridging through the roof fasteners holding its components in place, and this problem is not one to be ignored.
If your commercial building needs a new roof or repair, it might be time to call in a professional roofer. You might have a few contractors in your area, so knowing what questions to ask a roofer can help you find the right one for the job. In addition to requesting examples of their past work, here are eight questions to ask a roofing contractor before hiring them.
With the labor pool stretched thin, finding time-saving products is high on many contractors' to-do lists. Saving time doesn't mean jeopardizing quality as manufacturers continually work to deliver solutions that help increase efficiency while still delivering a first-class installation.
As a contractor, you're constantly on the lookout for ways to get the job done quickly while continuing to provide a high level of quality to customers. Carefully selecting the materials you use can help—and with new roofing technologies being developed every day, you have a lot of options.
