I live in a historical district, and when my roof started leaking a few months ago, you wouldn't believe how much trouble I had to go through to get a permit to repair it. I'd never had to make a major repair or change to my house before, so I didn't know what to expect. I understood that the district board wanted to be certain that I didn't make any major changes to the look of my house, but I still didn't think it would take so much red tape to get permission to patch up the roof.
Luckily, I worked with a roofing contractor who lives locally and who had been through this before. He understood what I needed and helped guide me through the process as much as possible. The experience showed me how helpful it can be to have a roofer that understands your local community.
