The 9 Best Roofing Companies Marathon Florida Has to Offer (2026)
By Shelly Marchetti, Florida homeowner advocate. Reviewed by Hal Winstead, Editor, licensed roofing contractor. I remember sliding out from under a raised stilt house on Coco Plum Drive the morning after Hurricane Irma rolled throught, hauling a soggy wad of insurance paperwork. The roof had peeled back like a sardine can lid, and the owner kept asking me if the next roofer would actualy show up. That question stuck, not just because of the damage, but because the whole street was waiting on tarps and promises.
So when I sat down to sort the roofers for Marathon, I did what I wish every homeowner would do: I checked each company against the Florida DBPR licence roll. Only two of the nine below came back with an active roofing licence. That surprised me, and it should surprise you too. You'll see the proof for yourself in every roofing company we list in Marathon, and that's the difference between a guess and a verifiable list.
Short answer: the 9 best roofing companies in Marathon, Florida are led by Luis Roofing inc, Advanced Roofing South, Inc and Keys All Area Roofing and Construction Inc. Of the 9 listed here, 2 hold a verified Florida DBPR roofing licence, which is the single check worth doing before anyone climbs on your roof. Rankings below use licence status, review volume, rating and photo evidence — all public, all reproducible.
If you would rather browse the full list rather than my shortlist, every one of them is on the Marathon roofing companies directory page — this post is the 9 I would call first.
How this list was ranked. Every company here was cross-checked against the Florida Department of Business and Professional Regulation licence roll; 2 of 9 returned an active roofing licence (type CCC or RC), and the licence number is printed on each entry so you can verify it yourself. After licence status, ordering uses Google review count (capped so a big chain cannot buy the top spot on volume alone), star rating, and whether the company has photos and published hours. Nobody paid to appear on this list.

How to check any Florida roofer's licence yourself
Search the licence number at the Florida DBPR licence portal. A roofing contractor holds a CCC (certified) or RC (registered) licence. If the number does not return an active record, that is the end of the conversation.
