## Answer

Late spring and early fall are generally the best times to replace a roof because ambient temperatures of about 45–85°F let asphalt shingle sealant strips activate properly without softening the mat; summer is workable but slower, winter installs require cold-weather adhesive protocols, and rain shuts every install down.

## Why temperature matters

Asphalt shingles use a factory-applied self-seal adhesive strip that activates with heat and pressure. Per manufacturer install guides (GAF, CertainTeed, Owens Corning), the strip needs sustained daytime temps above roughly 45°F to bond in the first weeks. Below that, roofers hand-seal every tab, which is slower and more expensive.

In summer heat above ~90°F, shingles become soft and can scuff under foot traffic, so most crews start earlier and stop by early afternoon.

## Scheduling reality

Late spring bookings are often set 4–8 weeks out; late fall books earliest because homeowners rush before winter. Storm season (May–October in most regions per NOAA SPC climatology) creates surge demand that can double lead times.
