Questions about soft roof decking.
Does soft roof decking always require roof replacement?+
No. The right recommendation depends on the cause, extent, surrounding condition, material availability, roof age, and repairability.
Can soft roof decking cause a roof leak?+
It may. Some visible conditions can allow moisture intrusion directly, while others increase the risk of future leakage or indicate a broader roof-system issue.
Can I inspect soft roof decking from the ground?+
