The answer to 'roof decking missing shingles' is that this is a common roofing issue that can be caused by a variety of factors, including age, weather damage, poor installation, or lack of maintenance. Missing shingles expose the roof decking, which can lead to leaks, water damage, and even structural problems if left unaddressed.
The symptoms of this issue may include visible gaps or holes in the roof, water stains on the ceiling or walls, and potential drafts or air leaks. To address the problem, the missing shingles will need to be replaced, and the underlying roof decking may need to be inspected and repaired if it has sustained any damage. In some cases, the entire roof may need to be replaced if the damage is extensive.
