CCC1332490
Certified Roofing Contractor
What this class typically covers
Typically may contract for roof installation, repair, and related roofing work within the certified roofing classification.
Good to know: Roofing projects often require local permits and wind-mitigation compliance. Confirm the exact system (shingle, tile, metal, flat) and warranty terms with the contractor.
Board discipline from Florida extracts linked to this contractor. Separate from insurance, permits, or reviews — factual records only.
No discipline records identified in current extracts
Our Florida board discipline files do not currently attach an action to this profile. That is not a certificate of clean history: records may exist outside these extracts, under another name, or after our last load. Re-check the official DBPR board before hiring.
What this means: absence in our extract ≠ cleared. Worth confirming on the official source the day you hire.

Why workers' comp matters (Florida)
If a contractor is required to carry workers' compensation and does not, you may face liability and project risk if a worker is injured on your job. Requirements depend on structure, employees, and exemptions — the Division of Workers' Compensation is the authority. Homeowner should confirm with carrier and official portals.

Public permit/work records linked to this contractor license by an exact license-number match. A permit record is not an endorsement, and more or fewer permits on file is not a quality signal. Where we cover
4 confirmed records · Miami-Dade County Open Data — Building Permits · retrieved 2026-08-27
Worksite location is the public permit address on file, not a confirmed service territory. A permit record does not confirm work was completed as scoped, and the absence of a permit here does not mean work was performed without one.
