Which practice most directly improves wind resistance of an asphalt shingle roof?

• A. Reducing nail quantity
• B. Painting the roof white
• C. Installing extra attic vents
• D. Following a proper nailing pattern

Answer: (D)

The main idea is that wind resistance for an asphalt shingle roof is gained by how securely the shingles are fastened. Following a proper nailing pattern ensures each shingle is anchored to the roof deck in the exact locations and with the correct spacing the manufacturer requires. This alignment and fastening hold the shingles down during gusts, especially along the edges, eaves, rakes, and around any corners or penetrations, preventing uplift and blow-off. Paint color or attic ventilation don’t directly improve how well the shingles are fastened to the deck. Reducing nails weakens the hold, making uplift more likely. Installing extra attic vents helps with ventilation, not with securing shingles against wind. So, using the manufacturer-recommended nailing pattern is the action that most directly enhances wind resistance.
