Roof installers have a wide range of skill levels.
The best crews are in high demand and expect to be treated well and paid well for their expertise.
Unfortunately, most discount roofers neither pay nor treat their installers well, so they are unable to attract and keep the best crews. Often, as a result, their roofs are not installed to the highest standards.
If you pay for the best shingles and components but they don’t get properly installed, what’s the point? There is a right way and a wrong way to install a roof, but usually homeowners cannot tell the difference by just observing. You should only hire a roofing contractor who is willing to document their
installation process in detail. If they are not, it’s generally because they simply do not want to be held accountable to a written standard.
While some discount roofers might provide a documented installation process, most are using low paid crews that are unlikely to follow it during installation. Underpaid crews are not paid enough to warrant that level of thoroughness.
Remember, “you get what you pay for”.
