Mary contacted RoofAdvisor after noticing a roof leak and concerns with aging gutters and roofing shingles on her Ann Arbor home. During the inspection, only minor roofing issues were found, but the attic revealed a larger underlying problem: poor ventilation and condensation buildup.
Inside the attic, several areas showed signs of black mold caused by trapped moisture rather than active roof leaks. The home lacked an intake ventilation system and had exposed overhangs that contributed to poor attic airflow and condensation over time.
Addressing the Root Cause with Ventilation Improvements
Rather than simply replacing shingles, the project focused on improving the entire roofing system’s long-term performance by correcting the home’s ventilation deficiencies.
The new roofing system included:
- GAF Timberline® HDZ™ Lifetime Architectural Shingles
- Synthetic underlayment
- Ice and water barrier protection
- Pro-Start® starter shingles
- Cobra® SnowCountry® Advanced Ridge Vent
- GAF Seal-A-Ridge® ridge and hip shingles
To improve attic airflow and help reduce future condensation issues, RoofAdvisor also installed:
- New edge vent intake ventilation
- Additional slant-back can vents
- Updated bath vent connections
These upgrades help create balanced intake and exhaust ventilation throughout the attic space.
Additional Roofing & Gutter Improvements
The project also included:
- New drip edge and flashing components
- Replacement plumbing boots
- Updated chimney flashing cut directly into the brick
- Step flashing improvements
- Steep slope roofing work on upper roof sections
Along with the roof replacement, RoofAdvisor completed gutter upgrades, including:
- New seamless gutters
- Replacement of one-story and two-story downspouts
Long-Term Protection & Peace of Mind
The completed project included:
- Full tear-off and waste removal
- Magnetic nail cleanup
- GAF System Plus Warranty
- RoofAdvisor 25-Year Workmanship Warranty
By addressing both the roofing system and the underlying ventilation, Mary’s new roof provides improved moisture control, dependable weather protection, and long-term peace of mind, built for Michigan weather conditions.
