Job description

Preman Roofing + Solar is looking for an experienced Commercial Roofing Estimator / Project Manager to join our team.

We're looking for someone who knows commercial roofing, understands how to put together accurate estimates, and can manage their own projects from start to finish.

This is a hands‑on role for someone who can estimate jobs, build relationships with customers and general contractors, negotiate contracts, and manage projects through completion.

We're looking for someone who knows the roofing business, not just someone who knows how to read plans and put numbers together.

What You’ll Do

• Review plans, specifications, and bid documents for commercial roofing projects.
• Prepare accurate estimates, takeoffs, proposals, and project budgets.
• Identify material, labor, equipment, and subcontractor costs.
• Work with general contractors, property managers, and customers to develop bids and secure projects.
• Manage your own awarded projects from contract signing through completion.
• Coordinate with superintendents, field crews, vendors, and subcontractors.
• Track project schedules, budgets, labor costs, and profitability.
• Handle RFIs, change orders, submittals, and project documentation.
• Attend job walks, preconstruction meetings, and project meetings.
• Identify problems early, find solutions, and keep projects moving.
• Maintain strong relationships with customers and general contractors.

Roofing Experience Required

You must have solid experience estimating commercial roofing systems, including:

• TPO and PVC single-ply roofing
• Torch-down and modified bitumen
• Built-up roofing (BUR)
• Fluid-applied roofing and waterproofing
• Silicone and other roof coatings
• Roof insulation and tapered systems
• Flashing, sheet metal, drainage, and waterproofing details
• Commercial reroofing and new construction

You should understand how these systems are installed, what materials and labor are required, and how to accurately price the work.

What We’re Looking For

• 5+ years of commercial roofing estimating experience.
• Experience managing commercial roofing projects from start to finish.
• Strong knowledge of commercial roofing materials, installation methods, and labor costs.
• Ability to read construction plans, specifications, and roofing details.
• Experience preparing competitive bids and negotiating contracts.
• Strong understanding of project budgets, scheduling, and job costing.
• Ability to manage multiple bids and active projects at the same time.
• Good communication, organization, and problem‑solving skills.
• Comfortable working independently and taking ownership of projects.
• Experience working with general contractors and commercial property owners.
• Familiarity with estimating and construction management software.
• Valid driver's license.

The Bottom Line

We’re looking for an experienced commercial roofing professional who can estimate the work, win the job, and manage the project.

You need to know your numbers, understand the roofing trade, communicate well with customers and field crews, and take responsibility for your projects.

We want someone who is organized, motivated, and comfortable making decisions without needing someone to hold their hand.

If you’ve spent years in commercial roofing, know how to put together a competitive bid, and enjoy seeing your projects through from start to finish, we’d like to talk to you.
