Proper roof ventilation is essential for regulating attic temperatures. To assess your ventilation, check if your attic feels excessively hot, has signs of moisture or mold, or if your energy bills are unusually high. Inspect intake and exhaust vents to ensure they’re unblocked and sufficient; typically, you need 1 square foot of vent area for every 300 square feet of attic space. If ventilation is inadequate, options include adding vents, using baffles to prevent blockages, or consulting a roofer for professional advice. Good ventilation improves energy efficiency, prevents roof damage, and keeps your home comfortable.

Hi there It’s quite rare for a roof leak to be caused by high-nailing. Typically, when a shingle is high-nailed, it prevents proper bonding with the roof, making it more susceptible to being blown off or shifting over time. Overall, I’d agree that replacing the entire roof is the best course of action, as repeatedly replacing individual shingles will likely lead to ongoing issues. I recommend reaching out to the original roofing company to see if they will honor a warranty for the work. High-nailing is absolutely a valid reason to file a warranty claim—it does not meet manufacturer specifications and should be corrected by the original roofer, regardless of whether their workmanship warranty has expired.
