Roof Repair vs. Replacement: 5 Factors Denton Homeowners Must Know
Not every roof leak requires a full replacement. Discover the 5 essential factors that determine whether a targeted repair or complete re-roofing makes sense.
Key Takeaways
- •Roofs under 10 years old with isolated leaks are ideal candidates for targeted repairs.
- •Widespread damage across multiple slopes favors a full system replacement.
- •Inspecting underlying plywood decking ensures load-bearing structural safety.
1. The Age of Your Current Roof System
Standard 3-tab shingles last 15 to 20 years, while architectural dimensional shingles last 25 to 30 years in North Texas.
If your roof is under 10 years old and develops an isolated leak near a pipe vent, a targeted component repair is usually the most cost-effective path.
2. The Widespread Extent of Damage
If damage is confined to a single roof slope or damaged ridge cap shingles, slope patch repairs work well. However, if hail impacts or shingle lifting affect multiple roof facets, full replacement offers better long-term protection.
3. Decking & Rafter Health Underneath
When water leaks go unaddressed, underlying OSB or plywood sheathing panels absorb moisture and soften. If structural decking is rotted across wide areas, re-roofing with new decking is necessary.
Frequently Asked Questions
Can I layer new shingles over my old roof?
