Understanding the Commercial Roofing Bidding Process
Bidding on a commercial roofing project in New Jersey requires a strategic approach that ensures profitability while remaining competitive. With the state’s diverse climate, building regulations, and competitive roofing industry, contractors must be meticulous in their cost estimations, material choices, and proposal presentations. With Charles Jimerson of CJ Commercial Roofing NJ, this guide will walk you through the essential steps to successfully bid on a commercial roofing project in New Jersey.

Step 1: Conduct a Thorough Site Inspection
Before preparing a bid, you must conduct a comprehensive site inspection. This step is crucial for assessing the scope of work and identifying potential challenges. Key factors to evaluate include:
- Roof Size and Complexity – Measure the total square footage and identify slopes, penetrations, and irregularities.
- Existing Roof Condition – Determine if there are damages, leaks, or issues that require additional repairs.
- Structural Integrity – Assess the building’s structural capacity to support roofing materials.
- Local Building Codes & Permits – Familiarize yourself with New Jersey’s roofing regulations and permit requirements to ensure compliance.
Step 2: Choose the Right Roofing Materials
New Jersey experiences a mix of hot summers, cold winters, and frequent storms, making material selection vital for longevity and durability. Common commercial roofing materials include:
- TPO (Thermoplastic Polyolefin) – Ideal for energy efficiency and durability.
- EPDM (Ethylene Propylene Diene Monomer) – A flexible and weather-resistant rubber membrane.
- Modified Bitumen – Known for its strength and ability to withstand temperature fluctuations.
- Metal Roofing – A long-lasting option with excellent weather resistance.
- Built-Up Roofing (BUR) – A traditional method offering multiple layers of protection.
Consider New Jersey’s energy efficiency incentives when selecting materials to appeal to property owners looking for cost savings.
Step 3: Calculate Labor and Material Costs
Accurate cost estimation is the backbone of a competitive and profitable bid. Key cost factors include:
