Joe Sobol, owner of Big Easy Construction in New Orleans, has bad news for homeowners who’ve been calling about roofs damaged by Hurricane Ida. The job will cost a lot more than usual — and take much longer, too. Ida slammed into the Gulf Coast — then took its destruction to the Northeast — at a time when building contractors were already grappling with severe shortages of workers and depleted supply chains. The damage inflicted by Ida has magnified those challenges. The struggle to find enough skilled workers and materials will likely drive up costs, complicate planning and delay reconstruction for months.
