The answer to 'why is my roof decking hail damage' is that hail strikes can cause significant damage to the plywood or OSB boards that make up your roof's decking. Hail impacts can crack, dent, or puncture the decking, compromising its structural integrity and ability to support the roofing materials above. This damage can lead to leaks, water intrusion, and further deterioration if not addressed promptly.
Symptoms of hail damage to the roof decking include visible cracks, holes, or dents in the surface, as well as potential sagging or unevenness of the roof. In some cases, the damage may not be immediately apparent, so it's important to have a professional roofing inspector assess the condition of your roof after a hailstorm.
