Summer Heat, Sun and Shingle Granules
Asphalt shingles are covered in small mineral granules. They give the shingle its color and shield the asphalt underneath from sunlight. Hot summers are part of what they are made to handle.
Granules in the gutter
A few granules in the gutters or at the bottom of a downspout are common, especially on a newer roof. A large, steady amount over time is worth noting.
Bare or dark patches
From the ground, look for spots where the shingle color looks uneven or darker than the area around it. Binoculars help. Those spots may mean granules have worn away.
Curling and cupping
Shingle edges that curl up or dip in the middle can point to aging, heat in the attic or ventilation issues. Note where on the roof you see them.
Attic heat and the roof
A hot attic warms the shingles from below. Good ventilation lets heat escape. If the upstairs rooms feel very hot in summer, it may be worth asking about attic ventilation.
