Houston's climate is brutal on roofs. If you're seeing any of these, it's time for a free Ranlock inspection.
Most asphalt shingle roofs in Houston's climate last 15–25 years. If your roof is approaching or past this range, a proactive replacement is smarter than waiting for a failure.
Excessive granule loss in downspouts or at the base of your downspouts means shingles are deteriorating. Bare spots in the shingle surface leave the asphalt directly exposed to UV.
Shingles that curl upward at edges (curling) or cup in the center have lost their structural integrity. They lift in wind and no longer seal properly against rain.
Ceiling stains or attic moisture are a sign the roof system has been breached. Often indicates underlayment failure, flashing issues, or shingle damage that has allowed water penetration.
Black or dark streaking is blue-green algae (Gloeocapsa magma) — extremely common in Houston's humidity. While treatable, repeated algae growth signals shingles without StreakGuard™ protection.
After hail or high winds, damage is often not visible from the ground. Microscopic hail impacts fracture the shingle mat and accelerate premature failure — only a professional inspection reveals the full picture.

Ranlock never pushes replacement when repair is the right answer. Here's how we help you decide.
| Factor | Repair | Full Replacement |
|---|---|---|
| Roof Age | Under 10 years old | 15+ years old |
| Damage Scope | Isolated — one area | Widespread across roof |
| Shingle Condition | Most shingles intact | Curling, granule loss, cracking throughout |
| Leak History | First-time or isolated | Recurring leaks, multiple areas |
| Insurance Claim | Partial damage only | Whole-roof storm damage — claim covers it |
| Long-Term Cost | Lower upfront | Better long-term value when near end of life |
| Warranty | Existing warranty (if active) | Fresh full system warranty |
| Ranlock Recommendation | Roof Tune-Up or partial repair | Full replacement — new system, new warranty |
