Roofing Case Studies

Case Study #1:

Storm Damage Recovery – West County Residence

The Situation
Severe spring hailstorm damaged multiple homes in West County. This 1990s colonial had hail-damaged Architectural shingles across 80% of the roof, compromised flashing, and an aging soffit/fascia system showing water intrusion signs.

Our Assessment

• Structural damage: moderate; roof decking intact
• Material: Previous shingles rated Class 1 (basic impact resistance)
• Secondary damage: Soffit/fascia rot requiring replacement
• Opportunity: Full system upgrade to prevent future damage
  

Our Recommendation

• Duration® Series Shingles, Class 4 – This home sits on an exposed knoll; wind and hail exposure is high. Class 4 impact rating protects against future storms. SureNail® technology prevents blow-offs in high wind.
• Enhanced ice & water barrier – Upgrade to full-roof coverage (not just eaves) given the exposure
• New flashing package – Transition from old, deteriorated aluminum to new, properly sealed flashing
• Soffit/fascia replacement – Prevent water intrusion from compromising the roofing system investment
  

The Outcome

• Materials Cost: ~$18,500 (full system, 2,800 sq ft)
  
• Timeline: 4 days
  
• Result: Insurance claim covered 85%; homeowner investment: ~$2,800
  
• Outcome: 40-year warranty, zero concerns about future weather damage in this home
  

Why This Matters

Many contractors would replace the shingles with similar-grade material. We upgraded the whole system. The homeowner's next roof conversation won't happen for 40 years—and they'll sleep better knowing this home can handle what the St. Louis spring throws at it.

Case Study #2:

Ice Dam Prevention & Hidden Moisture – South City Cottage

The Situation
A 1970s cottage with original asphalt shingles, poor attic ventilation, and recurring ice dam problems every winter. Previous homeowner had patched the interior damage multiple times. Moisture staining in the master bedroom suggested ongoing problems.

Our Assessment

• Roof age: 30+ years, end of life
• Ventilation: Inadequate (only soffit intake, no ridge exhaust)
• Moisture control: Failed—attic was trapping humid air
• Water intrusion pathway: Ice dams backing water up, then melting into the home
  

Our Recommendation

• New shingles – Oakridge® Series; appropriate for this home's exposure (sheltered street)
• Ventilation upgrade – Add ridge vent system to allow hot, humid attic air to escape
• Ice & water barrier – Full coverage to manage winter ice dam backup
• Attic inspection & repair – Seal air leaks that were allowing humid interior air into attic
• Soffit/fascia repair – Address rotted sections from previous moisture damage
  

The Outcome

• Materials Cost: ~$14,200 (full system, 1,800 sq ft)
• Timeline: 3 days
• Result: Insurance: $0 (age-related); homeowner investment: $14,20
• Outcome: Ice dams eliminated after first winter; interior moisture staining stopped
  

Why This Matters

The cheapest fix was new shingles. But without fixing ventilation and air sealing, the problem would have repeated in 3-5 years. We diagnosed the root cause (ventilation failure) instead of treating the symptom (ice dams). First winter verified: zero ice dams, zero new water staining.

Case Study #3:

Restoration After Water Damage – Clayton Historic Home

The Situation
A 1920s Tudor revival with previous roof leak damage from failed flashing around a chimney. Spot repairs hadn't solved the problem; water was still entering the attic. Homeowner wanted the entire roof restored to like-new condition.

Our Assessment

• Roof structure: Solid; no deck damage if leak gets stopped
• Previous repairs: Inadequate—flashing installed over water stains without removing existing debris/moisture
• Material: Original steep slate was attractive but aging; asphalt shingle restoration was the practical choice
• Water pathway: Chimney flashing was the sole issue; roof itself was sound elsewhere
  

Our Recommendation

• Full roof replacement – Duration® Shingles, Charcoal Gray to complement the home's historic character
• Custom chimney flashing – Remove old, deteriorated flashing; install new step flashing with proper overlap and sealant
• Underlayment upgrade – Synthetic underlayment across entire roof for superior moisture management
• Soffit/fascia restoration – Restore rotted wood to maintain the home's architectural character
  

The Outcome

• Materials Cost: ~$22,000 (full system, 3,100 sq ft)
• Timeline: 5 days
• Result: Insurance claim (water damage): $6,500; homeowner investment: ~$15,500
• Outcome: Zero moisture signs after first year; roof restored to original aesthetic intent
  

Why This Matters

Historic homes need solutions that match their character. We consulted on shingle color to ensure the new roof respected the home's 1920s design. The key technical win: proper chimney flashing that stops water at the source, paired with a complete system approach. One year later, no moisture concerns.

What These Cases Have in Common

1. Complete system thinking – Never just shingles. Ventilation, flashing, underlayment, and deck condition all matter.
2. Regional expertise – We understand how St. Louis weather creates ice dams, moisture problems, and storm damage. Our recommendations reflect that.
3. Root cause diagnosis – We find the real problem, not just the symptom.
4. Material matching – Right product for right exposure (Duration® for exposed homes, Oakridge® for standard homes, etc.).
5. Long-term results – These homes are performing years later because we didn't cut corners.
