Do I need a New Roof

Leaking roofs, poor drainage, and clogged gutters and downspouts can lead to significant water damage inside your home. To help determine if you need a new roof, your roofing contractor will conduct an outside and inside roof inspection.

Inspecting a roof from outside is very simple. All that is needed is a pair of binoculars and a viewing point that is unobstructed by other buildings or trees. Following is a checklist of problem signs you can look for during an outside roof inspection.
