Pliability is a shingle’s ability to bend without cracking or breaking. This is important, especially in colder weather when materials can become stiff and brittle. If shingles stay flexible, they can be installed in different temperatures and will handle the natural expanding and contracting without cracking, which helps prevent leaks and damage over time.
Why Pliability Matters for Your Roof
When temperatures drop, asphalt shingles naturally become less flexible. This brittleness creates several problems. During installation, stiff shingles are more likely to crack when bent around roof edges or when installers walk on them. After installation, the constant cycle of expansion and contraction from temperature changes can cause rigid shingles to develop stress cracks.
These cracks aren’t just cosmetic issues. They create entry points for water, leading to leaks that can damage your home’s structure, insulation, and interior. In regions with harsh winters, maintaining shingle flexibility is essential for long-term roof performance.
The Science Behind Shingle Flexibility
Fresh Roof addresses this challenge through advanced treatment technology. The product works by restoring the natural oils in aging asphalt, which gradually dry out over time. This restoration process brings back much of the shingle’s original flexibility while maintaining its protective properties.
The treatment penetrates deep into the asphalt matrix, rebuilding the molecular structure that gives shingles their ability to flex. This isn’t just a surface coating but a comprehensive restoration that affects the entire shingle material.
Impressive Test Results
During independent testing performed by PRI, an accredited third-party testing facility, Fresh Roof demonstrated remarkable improvements in shingle pliability. The control shingle achieved a pliability rating of -3, while the Fresh Roof-treated shingle scored -6, representing a 100% improvement in pliability.
This doubling of flexibility means treated shingles can bend significantly more before reaching their breaking point. For homeowners, this translates to better performance during installation, reduced cracking from thermal stress, and longer overall roof life.
Real-World Benefits
The enhanced pliability delivers practical advantages you can see and feel. Installation becomes easier and safer, with fewer broken shingles during the roofing process. Your roof handles weather extremes better, from scorching summer heat to frigid winter cold.
Most importantly, the improved flexibility extends your roof’s lifespan. Shingles that can bend without breaking last longer and require fewer repairs. This flexibility also means better wind resistance, as pliable shingles can flex with wind forces rather than fighting against them.
During testing, the control shingle had a pliability rating of -3, whereas the Fresh Roof-treated shingle achieved a rating of -6, representing a 100% improvement in pliability. This significant enhancement ensures that Fresh Roof-treated shingles remain more flexible and durable over time, especially in colder environments, reducing the risk of cracking and increasing the overall lifespan of the roof.
