Long, bright summers are great for yards and solar panels, but they take a toll on roofing materials.
Granule loss on shingles
UV exposure loosens the protective granules on shingle roofs. As more granules wash into gutters, the asphalt beneath is exposed and ages faster.
Drying and shrinking
Heat cycles can dry and shrink components, opening small gaps at joints, penetrations and flashing points.
Why ventilation matters
Attic ventilation helps moderate temperatures under the roof deck, which can extend roof life and improve comfort inside the home.
