If you’re concerned about the future of your roof – and your building – then it’s essential that you hire a third-party roof construction observation expert to oversee your roofing project. In the course of replacing your roof, you’ve likely become aware of the problems that have developed: leakage, mold, algae, poor insulation, or low-quality materials. When looking toward the future, you should consider the impact that these problems have had on your roof’s longevity and, more importantly, how you can avoid similar pitfalls with your new roof.
