This is the Key Biscayne page for flat & low-slope roofing. The short version: you want a quote for a flat or low-pitch section that shingle roofers keep declining, and you can have it without a salesperson at the door.
Get a written quotePlank decking instead of plywood is common in this era, and it's the reason a quote must price decking replacement per sheet up front. Most homes predate 1980, so many are on their third or fourth roof and code limits on layers become a real constraint at tear-off. A sealed roof deck — peel-and-stick underlayment over every seam — earns secondary water resistance credit on the wind mitigation form and is worth asking for by name.
On cost: priced per square like any roof but with a wider spread; TPO and modified bitumen are the common systems, and a silicone coating over a sound existing membrane is the lowest-cost path when it qualifies.

How it works
Not every residential roofer. Ask specifically whether the crew installs low-slope membrane or subs it. The tie-in between the flat section and the pitched roof is where leaks start.
TPO is a heat-welded single-ply, white, and reflective — good in Florida and Texas heat. Modified bitumen is torch- or self-adhered asphalt, more forgiving on complex details. Both are fine when installed right.
