Valley leaks
Where two roof slopes meet
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.
South Coffeyville sits where the southern plains storm season is as severe as anywhere in the country. Hail is the dominant roof killer, and it works slowly — bruising the asphalt mat under the granule surface without breaking through, so the roof keeps water out for another season or two and then fails from a spot damaged years earlier. Straight-line wind arrives with the same systems and lifts shingle tabs without removing them, leaving a roof that looks untouched and leaks at the next rain. Nowata County also gets real temperature swing, which works flashing joints loose over time, and the occasional ice storm that loads a roof in a way nothing else does. Claim volume here is high enough that storm-chasing contractors follow the hail, which is its own problem for homeowners.
South Coffeyville has a population of about 694, and the housing stock here sets the pattern for what fails first on a roof.
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.
