Can a Roof Void Workmanship Coverage If Damaged by Ice Damming?

Roofing product coverage is a manufacturer's agreement about their shingles or tiles. It typically addresses issues like premature granule loss or manufacturing flaws that cause the product to fail. This agreement does not cover damage from external events like storms, fallen branches, or water intrusion from any source, including ice dams. The coverage applies only to the specific materials, not the roof's performance as a whole.

To keep this coverage in effect, you must follow the manufacturer's exact installation guidelines. This includes using the correct underlayment, fasteners, and ventilation as specified. If a roofer deviates from these instructions, the coverage may be invalid from the start. Proper attic ventilation is a common requirement that directly impacts ice dam formation, making adherence critical for protection.

Several common actions can invalidate a roofing product's coverage. Improper installation is the primary cause, such as incorrect nailing or insufficient underlayment. Failure to maintain the roof system, like not clearing debris from valleys or ignoring damaged flashing, also invalidates it. Any alteration to the roof structure that affects ventilation or drainage can be grounds for invalidating the coverage as well.

Adding new roof layers over old ones often invalidates coverage, as manufacturers require a full tear-off for proper installation. Using unapproved repair materials or methods after a leak occurs will also nullify the agreement. It is crucial to read your coverage document carefully and understand all its exclusions and maintenance requirements to avoid accidental invalidation.

• Improper installation not following manufacturer specs
• Lack of adequate attic ventilation and insulation
• Failure to perform routine maintenance and repairs
• Adding a second layer of shingles over the old roof
• Repairs made with non-approved materials or methods
• Damage from neglect, storms, or acts of nature

Prevention focuses on keeping your attic space cold to minimize snow melt. Increase attic insulation to recommended levels for your region to stop heat loss from living spaces. Ensure soffit, ridge, and gable vents are clear and functional to allow cold air to circulate. Proper ventilation helps maintain a uniform roof temperature, preventing the cycle of melting and freezing that creates dams.

Seal all air leaks from your home into the attic, such as around light fixtures, plumbing stacks, and attic hatches. In climates with cold winters, this is especially important. Keep gutters clean so melting snow can drain freely. Consider installing a water-repellent membrane under your shingles at the eaves during your next reroofing project for added protection.
