In Texas, start thinking about a new roof when shingles are curling, cracked, or missing granules, or if you see daylight through the attic. After a big hail or wind storm, inspect for dents or torn flashing. Also, if your roof is over 20 years old, water stains appear on ceilings, or energy bills spike, it's likely time to replace it before summer heat makes things worse.
