Snow and Ice
Solar panels can still generate electricity during winter months, even in colder temperatures.
Freeze-Thaw Cycles
Midwest weather regularly shifts between freezing and thawing conditions, making roof inspections important before solar installation.
Summer Heat
Solar panels are designed for outdoor exposure and can handle high temperatures.
Why Roof Condition Matters Before Solar Installation
Solar systems are long-term investments. The roof supporting them should ideally have a similar remaining lifespan.
Common warning signs include:
– Roof age over 15–20 years
– Missing shingles
– Active leaks
– Water stains
– Hail damage
– Sagging roof areas
