Torsion vs extension, wire size and cycle rating.
01When panel replacement works
Single damaged sections from a car bump, hail or wind can often be replaced. Matching color and style matters, especially on older doors or doors faded by sun.
02When a new door makes sense
If multiple panels are damaged, the model is discontinued, or the door lacks insulation you want, new garage door installation may cost less overall.
03Insurance
Storm or vehicle damage may be covered by homeowner or auto insurance. Photograph damage first.
