TL;DR: Alamo roof problems follow predictable patterns by build era. Pre-1985 downtown homes have decking + flashing failures. 1990s-2010s Tower Rd corridor tract housing shows pipe boot + sealant issues. 2010s+ agricultural-fringe new construction has builder-grade ventilation imbalance.

2. Failed flashings at chimneys + parapets — 40+ year sealant. Fix: $1,500-$8,000.
