Fair points overall, but I'd hesitate to pin too much blame on ventilation alone. A few things I've noticed managing properties:
- Even with solid attic airflow, I've seen adhesive strips fail prematurely—sometimes it's just a bad batch or quality control issue.
- Crews rushing late-season installs is definitely a factor, but honestly, I've had shingles installed mid-summer with similar bonding issues. Temperature isn't always the culprit.
- Agree ice dams are brutal, but sometimes the roof pitch itself is overlooked. Lower-pitched roofs seem to struggle more regardless of ventilation improvements.
Not dismissing ventilation at all—it's important—but from experience, shingle quality and installation technique can be equally critical. Had one property where we upgraded vents and soffits, yet still had curling shingles within two winters. Turned out the shingles themselves were defective...manufacturer even admitted it later.
Just saying, ventilation helps, but it's not always the silver bullet.
Good insights here, especially about roof pitch. I've noticed similar issues on my own home—it's a lower-pitched roof, and even after upgrading ventilation, I still had some shingles curling prematurely. At first, I thought it was just poor installation, but after talking to neighbors with similar roofs, it seems pitch really does play a bigger role than I initially realized.
One thing I'm curious about though: has anyone found certain shingle brands or product lines that seem to hold up better on lower-pitched roofs? I'm budget-conscious, so I can't exactly spring for premium shingles across the board, but if there's a mid-range option that's proven reliable, I'd definitely consider it. Seems like manufacturers don't always clearly specify suitability for different pitches, which makes choosing the right product a bit tricky...
