I, too, used Brother's Roofing on a single family home sized roof. I consistently recommend them. People comment that they are expensive but, given my experience, I'd rather pay more up front than have to pay more later to fix their mistakes.

Thanks to the previous owner, when they pulled up the roof we had to replace SIX plywood boards and I think we paid an extra $500. The itemized list of work was 2 pages and the total was $13k or so. Came with a 25y, transferable warranty for materials and workmanship.

When I sold the house a few years later, the buyer's inspector tried to say our roof was sagging and suggested we replace the entire thing. I immediately called Brothers who sent someone out to check, for free, and tell the inspector (who, it turns out, didn't even get on the roof) to shove it.

I would pay "extra" for them 100 times out of 10.

Tunnels and bridges. I don't know how far away they have primary jurisdiction but I've seen em as far out as Hollins Ferry exit on the south side of the beltway.

That's one of the two tunnels - it's City but MDTA.
