A calm next step after rough weather.
Record what you can safely see from the ground. A professional inspection can help establish the condition and the scope of any work.
Stay on the ground.
Do not climb onto a damaged or icy roof. Keep clear of downed wires and unstable structures. If there is immediate danger, contact emergency services.
Document the visible concern
Note when you noticed it. Take ground-level photos only if it is safe to do so.
Arrange an inspection
Ask for photographs and a written description of the observed conditions.
Keep the paperwork together
Save the inspection, scope, and communications. Ask your insurer about its process if you are considering a claim.
