Roof Replacement Project in Rochester, NY – Built for Long-Term Performance
At Rochester Pro Roofing, every roof replacement is approached with one goal in mind: install a system that performs reliably for decades, not just a quick surface fix. This recent project is a strong example of how proper tear-off, ventilation upgrades, and material selection all come together to create a long-lasting roofing system.
Full Tear-Off of Multiple Layers
This home originally had two layers of three-tab shingles, which is something we see often in Rochester. While local code may allow multiple layers, installing over existing shingles compromises the lifespan of the new system and hides potential issues underneath.
We performed a full tear-off down to the decking, ensuring we were starting from a clean, solid base. This allows us to properly inspect the structure and address any underlying problems before installing new materials.
Decking Repairs Where It Matters Most
During the tear-off, we identified areas of concern—especially over the porch and in sections where leaks had been occurring. These are common failure points, particularly around transitions and lower-slope sections.
We replaced the compromised plywood in those areas to restore structural integrity. This step is critical. Roofing over damaged decking will always lead to premature failure, regardless of the shingle quality.
Ventilation Upgrade – Ridge Vent Conversion
Ventilation is one of the most overlooked aspects of roofing, but it plays a major role in roof longevity.
On this home, we:
- Kept the existing power vents to maintain active airflow
- Removed all box vents
- Installed a continuous ridge vent system
This creates a more balanced and efficient airflow across the entire attic space. Ridge vents allow heat and moisture to escape evenly, reducing the risk of:
- Ice dams in winter
- Excessive heat buildup in summer
- Premature shingle deterioration
Custom Metal Valleys for Durability
Valleys are one of the highest water-flow areas on any roof, and they need to be handled correctly.
For this project, we installed custom metal valleys instead of relying solely on shingle-based valley systems. Metal valleys provide:
- Superior water shedding
- Longer lifespan
- Better resistance to wear and erosion
This is a detail that significantly improves long-term performance, especially in Rochester’s climate where heavy rain and snow are common.
Ice & Water Protection
Given the weather conditions in upstate New York, proper waterproofing is non-negotiable.
We installed 6 feet of ice and water shield along all eaves and in critical areas such as valleys and penetrations. This creates a watertight barrier to protect against:
- Ice dam backups
- Wind-driven rain
- Snow melt infiltration
This layer is one of the most important defenses against leaks.
Full Owens Corning Duration Roofing System
For the shingle system, we installed Owens Corning Duration shingles, known for their durability and strong wind resistance.
This wasn’t just a shingle install—it was a complete Owens Corning roofing system, which includes:
- Ice & water barrier
- Synthetic underlayment
- Starter shingles
- Duration architectural shingles
- Ridge cap shingles
- Proper ventilation components
Using a full system ensures all components work together, which improves both performance and warranty coverage.
Matching Shed Roof Replacement
To complete the project, we also replaced the shed roof, matching it to the main house. This provides:
- A consistent appearance across the property
- Equal protection for all structures
- Increased overall property value
Too often, secondary structures are overlooked—but they’re just as exposed to the elements.
Built to Last
This project highlights the difference between a basic roof replacement and a properly engineered roofing system. Every step—from tear-off to ventilation to material selection—was done with longevity in mind.
At Rochester Pro Roofing, we don’t cut corners. We install roofing systems designed to handle:
- Heavy snow loads
- Freeze-thaw cycles
- High winds
- Long-term wear
If you’re considering a roof replacement in Spencerport or the surrounding areas, the goal shouldn’t just be a new look—it should be a system that performs for decades.
Rochester Pro Roofing installs roofs the right way—so you don’t have to think about it again for a long time.
