How Cold Is Too Cold for Roofing? A Quick Guide

Roofing is one of the few construction jobs done directly in the elements, and cold weather has a major impact on both safety and material performance. Homeowners often wonder: How cold is too cold for roofing?

Why Temperature Matters

Roofing materials need to flex, seal, and bond properly. When it gets too cold:

Shingles become brittle Sealant strips don’t activate Underlayments stiffen Roof surfaces become icy and unsafe

The Temperature Breakdown

Asphalt Shingles

Most common roofing material

Recommended minimum: 40°F (4°C)

Below this, shingles may crack and won’t seal unless hand-sealed.

Flat Roofing (EPDM, TPO, PVC)

EPDM: workable to 25–30°F

TPO/PVC: avoid below 20–25°F

Metal Roofing

Can be installed in colder temps, but crews usually stop below 20°F due to contraction and icy surfaces.

Crew Safety

Regardless of materials, roofing is typically paused when:

Temps fall below 10–20°F Wind chill becomes dangerous Ice forms on the roof

Bottom Line

Yes, roofing can be done in winter—but only when conditions allow materials to perform correctly and crews can work safely. Below freezing, most contractors slow down or stop work altogether to protect both quality and safety.
