Frequently asked questions

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?+

You may be able to photograph visible conditions from a safe location, but a ground-level view cannot confirm the full extent, cause, or repairability of the problem.

Should soft roof decking be inspected after a storm?+

Yes, especially when the condition appeared after wind, hail, heavy rain, falling branches, or another severe weather event.
