Ceiling leak and water stain
Stains, bulges and damp patches inside
Underlayment is the layer between decking and covering, and it is the roof's second line of defence — the thing that keeps water out when wind drives rain under a shingle course. Felt becomes brittle and tears; synthetic lasts longer but still degrades where it has been exposed. It is only accessible when the covering is off, so it is replaced during a re-cover or a large repair rather than on its own, and skipping it to save money removes the backup entirely.
Ben Hill County is far enough south to take the inland remnants of Gulf and Atlantic hurricane systems, and that is the storm profile that matters here. By the time these systems reach Ben Hill County the wind has dropped below the headline numbers but is still sustained for hours, which does something different to a roof than a short violent gust — it works shingle tabs loose over an extended period and drives rain horizontally under courses that would shed a normal downpour. The heat and humidity do the rest. Roofs here run hot for most of the year, which ages the shingle and hardens every rubber and sealant component, and the humidity means anything that gets wet inside the roof stays wet.
It is the only thing between wind-driven rain and your decking once water gets under a shingle course — which happens on every roof in a hard storm. Omitting it is why some roofs leak despite looking perfect from outside.
Synthetic is lighter, tears less, and tolerates exposure far better if the job runs over several days. Felt is cheaper and perfectly adequate when covered promptly. On a steep or exposed roof, synthetic is worth the difference.
