The answer to 'why is my roof decking cracked' is that cracked roof decking is often caused by excessive weight, structural damage, or moisture issues. Roof decking is the base layer that supports the roofing materials, and cracks can occur due to heavy snow loads, water damage, or underlying structural problems in the home.
Some common symptoms of cracked roof decking include visible cracks or splits in the wood, sagging or uneven roof surfaces, and water leaks. If left unaddressed, cracked decking can lead to more serious issues like roof collapse or extensive water damage. In many cases, repairing cracked decking requires the expertise of a professional roofing contractor, as it may involve replacing damaged sections or reinforcing the roof's structure.
