If you own a Baltimore row home with a flat roof, pricing can feel all over the place.
Homeowners are often quoted thousands apart for the same roof—without a clear explanation why.
In this guide, we break down the real cost ranges, what drives those prices, and how TPO, rubber roofs, and coatings compare—not just upfront, but over time.
By the end, you’ll know what your roof should cost—and which option actually makes sense for your home and budget.

Flat roof pricing isn’t straightforward—and that’s where most homeowners get stuck.
You’ll get one quote for $9k, another for $18k, and no one really explains what the difference is.
This guide breaks it down in plain terms—what TPO, rubber (modified bitumen), and coating systems actually cost around Baltimore, what drives those numbers, and where people usually overpay.
It’ll give you a solid ballpark for your own roof before you even talk to a contractor.
