The answer to 'how to maintain roof decking' is to regularly inspect and repair your roof decking to prevent damage and extend its lifespan. Roof decking is the structural base that supports your roofing materials, so it's essential to keep it in good condition.
Start by visually inspecting the decking from the attic or roof access point at least once a year. Look for any signs of water damage, rot, or deterioration. Pay close attention to areas around chimneys, vents, and other roof penetrations where leaks are more likely to occur. If you find any issues, address them promptly to prevent further damage.
