Estimates and pricing are one of the most difficult things for a roofing company. Not only is it dependent on factors such as the square footage size of your commercial roof, but also materials, labor, and other business costs such as insurance.
Let’s dive into the key factors that will influence the price and a general estimated range.
Estimating the Cost of a Commercial Roof in San Diego
Roof Size (Square Footage):
This is the most significant factor. Larger roofs will naturally cost more.
Type of Roofing Material:
Different flat roofing materials have different costs.
Common commercial roofing options include:
TPO (Thermoplastic Polyolefin):
A popular, energy-efficient, and durable option.
PVC (Polyvinyl Chloride):
Known for its durability and resistance to chemicals.
EPDM (Ethylene Propylene Diene Monomer):
A rubber-like material that is cost-effective and durable.
Modified Bitumen:
A multi-layered system that offers good waterproofing.
Built-Up Roofing (BUR):
Traditional system with multiple layers of felt and bitumen, often topped with gravel.
Condition of the Existing Roof:
If your current roof needs extensive repairs or if there are multiple layers that need to be removed, this will add to the cost.
Complexity of the Roof:
The number of penetrations (vents, skylights, HVAC units), drains, and parapet walls can affect the labor and material costs.
Accessibility:
How easy is it to access your roof? If special equipment or permits are needed for access in downtown San Diego, this could increase the cost.
Contractor Costs:
Labor rates and overhead vary between roofing contractors.
Warranty:
The type and length of the warranty offered can also influence the price.
Local Building Codes, Permits and Regulations:
San Diego has specific building codes that need to be met, which might influence material choices and installation methods.
General Estimated Cost Range (Per Square Foot): While these are broad estimates and can vary, here’s a general idea of what you might expect to pay per square foot for a new commercial flat roof in the US.
Keep in mind that some places like downtown San Diego might have slightly higher costs than other areas due to issues with parking, height of business buildings, and safety concerns in areas dense with pedestrians and traffic.
Lower End (e.g., EPDM): $7 – $9+ per square foot
Mid-Range (e.g., TPO, PVC, Modified Bitumen): $9 – $14+ per square foot
Higher End (e.g., Built-Up Roofing with multiple layers): $11 – $16+ per square foot
To get a more accurate estimate for your specific business, we highly recommend you:
Measure your roof: Have a professional like one of our expert roofers at Alma Roofing do this for you. Roofs are very dangerous, especially older ones that need replacement. An expert can determine the exact square footage of your flat roof.
Decide on the type of roofing material and additional specific needs: Research the different options and consider your budget, desired lifespan, and energy efficiency needs. Before we create an estimate, we review the pros and cons of the different roof options for your businesses current state and future needs, as well as you budget. A discussion should also take place about vents, solar, gutters or drainage, and other important accessories on a roof.
