A Gutter Sub Contractor is an independent contractor who installs, repairs, and maintains gutters for residential or commercial properties. They typically work under a primary contractor or company, handling specific projects on a contractual basis. Responsibilities include measuring, cutting, and securing gutters, ensuring proper drainage, and sometimes replacing fascia and soffit. Since they operate as subcontractors, they must have their own tools, transportation, and insurance. This role requires experience in construction, roofing, or exterior home improvement.
