Are a few missing shingles bad?

Yes, even a few missing shingles can pose a serious threat to the health and structural integrity of your roofing system if they are left unaddressed for too long. Shingles are not merely decorative; they serve as the primary defensive armor of your roof, shielding the delicate waterproof underlayment and wooden decking from driving rain, melting snow, and harsh ultraviolet radiation. When a few shingles blow off, the exposed underlayment is subjected to accelerated wear, tearing, and UV degradation, which can quickly lead to water infiltration, wet attic insulation, and costly interior ceiling damage. Furthermore, missing shingles compromise the wind resistance of neighboring shingles, as the interlocking seal is broken, making the surrounding area much more susceptible to peeling back during the next heavy windstorm. Promptly patching or replacing missing shingles prevents minor cosmetic issues from turning into major structural repairs.
