Ice can expose weak areas
When snow melts and refreezes near the roof edge, water may back up under shingles if the roofline or ventilation is struggling.
Interior signs matter
Ceiling stains, peeling paint, damp insulation, or attic frost can help narrow down whether the issue is roof-related or ventilation-related.
Plan the right repair
Some winter problems need temporary protection first and a more complete repair once weather allows safe work.
