Sincere Contractors LLC d/b/a By The Book Roofing.
A plain-spoken Florida roofing company built around one idea: prices published, everything in writing, nobody sent to your door.
Who we are
By The Book Roofing is the roofing brand of Sincere Contractors LLC, a Florida company. By The Book Roofing is a trade name ("doing business as"), and any contract you sign shows both names, exactly as required.
We built this company around a simple frustration: roofing quotes in Florida are too often a mystery until someone is standing in your living room. For homeowners on a fixed income, especially in 55+ manufactured home communities, that's stressful in a way it shouldn't have to be.
So we do it differently: publish the price, put everything in writing, and never send anyone to your door to close a sale. That's the operating rule behind how quotes, contracts, and install days work here.

Why we publish our prices
Because a fair price shouldn't depend on how well you negotiate with a stranger in your living room.
The price is public
$895 per square for the 45-mil insulated TPO system, $995 for the 60-mil. The same numbers for every customer, on the published price sheet, effective Jul 21, 2026.
Everything in writing
The quote, the exact spec, the warranty, and your 3-day right to cancel are all stated in the documents you keep, before work starts.
Discounts printed, not whispered
A $500 discount on the 20-year roof-over for homeowners 55+ and active-duty or veteran military. One per job, printed on the price sheet.
How we work
- No door-knocking. Nobody is sent to your door, and there's no commissioned closer in your living room. Quotes come by satellite measurement and phone.
- A permit pulled on every job, with the Florida product approval cited on every contract.
- The two-layer rule, stated up front. Florida code allows a maximum of two roof layers. If your home already has two, tear-off comes first. That starts at $100 per square, stated in your written quote before work starts.
- Your 3-day right to cancel, stated by us, unprompted.
Honest about being early
We're a newer brand building a track record in Florida parks, starting in Tampa Bay. We'd rather say that plainly (see our Reviews page) than pretend to a history we don't have yet.
So you won't find invented review counts or stock-photo "crews" here. As real jobs are completed, they'll show up on the Reviews page, and nowhere before that.
