The Guide to Asphalt Shingle Roofing Installation in Cold Weather

Pre-Installation Recommendations

Understanding Manufacturer’s Instructions

It is imperative to meticulously follow the manufacturer’s installation instructions, as this is a prerequisite in most building codes. This includes adhering to recommendations regarding cold temperature application, and proper storage and handling of accessory components used in the asphalt shingle roofing system.

Safety Precautions on Sloped Roofs

Working on sloped roofs in winter can be treacherous due to nearly invisible ice or frost build-up. We recommend postponing shingle roof application until the roof surface is completely free of ice and frost, ensuring a safer working environment.

Handling and Storage of Shingles

Cold Weather Implications on Shingles

Asphalt shingles tend to become less flexible as temperatures drop. It is crucial to choose an installation temperature where the shingles remain sufficiently flexible to facilitate installation. Shingles should be stored indoors to keep them warm prior to application, ensuring they remain pliable.

Proper Nailing Techniques

Ensuring that the shingles are flat during nailing is vital, as any curvature can result in the nail breaking through the shingle surface. Additionally, avoid bending, throwing, or dropping bundles of shingles in cold weather to prevent cracking or breaking.

Installation Techniques

Special Care for Lifting and Bending

Extra care, including warming of shingles, is necessary in applications where lifting or bending the shingle is required. This is particularly crucial for racking applications, hip and ridge shingles, or at valleys, as these actions may cause the shingles to crack or break during or after installation.

Hand-Sealing in Extremely Cold Weather

Most asphalt shingles include a thermally activated asphalt sealant that bonds the shingles together after application. In very cold weather, to provide additional protection from wind blow-off, shingles can be hand-sealed with an approved asphalt roofing cement or other adhesive acceptable to the shingle manufacturer.

Consideration for Metal Valleys

In cold weather, we recommend the use of open metal valleys, as woven and closed cut valleys necessitate bending of shingles, which may result in damage.

Additional Considerations for Re-Roofing

Ensuring a Smooth and Flat Roof Surface

When re-roofing over an existing roof in cold weather, it is crucial to ensure that the roof surface is smooth and flat. This prevents the uneven appearance of shingles, which may be “locked in” even after the return to warmer weather.

Adequate Attic Ventilation

Ensuring that the attic space is adequately ventilated is a critical step in the installation process. This prevents moisture buildup, contributing to the longevity of the roofing system.

Ice Dam Protection

In regions susceptible to ice damming, the installation of polymer modified, self-adhering underlayment is recommended. This provides protection against water backup from ice dams at the eaves of the roof. Alternatively, asphalt saturated felt may be used, provided it is applied per the manufacturer’s instructions and building code requirements.

Post-Installation Care and Maintenance

Caution During Roof Maintenance or Inspection

Special care should be taken when walking on shingles, especially in cold weather, as they are susceptible to breakage. Additionally, in cases where roof traffic may break the sealant bond, it may be necessary to hand-seal the shingles.

Snow and Ice Removal

In regions with high snowfall, removing snow and ice from the roof is essential. However, extreme caution must be taken to prevent damage to the shingles.
