Professional roofing contractors generally agree that while roofing projects can be done in any temperature, most experts advise against roofing when the temperature drops below 40 degrees, or when it climbs to higher than 85 degrees.

What temperature is needed for shingles to seal?

Shingles won't seal unless they warm to an ambient temperature near 70 degrees. That doesn't mean it needs to be 70, because solar radiance will heat the shingles even if temperatures are in the 40s. However, springtime can be a challenge due to rainfall.

The softening point for asphalt (which is does not mean the point at which it liquefies and runs) is 54-173°C or 129.2° - 343.4° F, though when reduced with other solvents the melting point can be reduced.

Why do roofers wear black?

Black indeed absorbs heat but the space between the black cloak and the girl's body (thanks to the loose-fitting) creates a kind of chimney effect moving the heat upwards and out through the top of the garment. This cooling principle wouldn't work if she was wearing a form-fitting black shirt, however.

If you have a roof leaking in winter and it's not caused by an ice dam, your attic insulation could be to blame. The conditions that lead to an ice dam can also create extra condensation in your attic, as well. If your attic insulation isn't up to par, too much warm air could enter that space.

What happens if it rains while installing shingles?

Both rain and high humidity can create enough moisture to prevent shingles from adhering properly to your roof. Plus, any moisture or water that gets trapped underneath these newly installed shingles can cause the wood underneath to rot and grow mold.
