Baccaro Roofing GuideCommon Alamo Roof Problems by Decade Built
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.

1. Decking rot — 1950s-70s plank decking. Fix: $300-$1,500 per area; full re-deck $5,000-$15,000.
2. Failed flashings at chimneys + parapets — 40+ year sealant. Fix: $1,500-$8,000.

2010s+ Alamo homes (agricultural fringe, newer subdivisions)
