A roof shouldn’t have dips, waves, or drooping areas, and when it does, there’s usually a reason.
On this job site, our estimator found that water was getting into the valley area due to improper valley installation.
Over time, that moisture made its way into the plywood underneath the shingles, causing rot and weakening the roof deck.
The result? Visible dips and drooping areas across the roof.
Problems like this often start small, but once water reaches the underlying structure, the damage can continue to spread.
Your shingles are only one part of your roofing system. Proper installation, flashing, valleys, and water management all play a role in protecting your home.
If your roof has visible dips or areas that don’t look right, it may be time to have it inspected.
