There are many factors that can affect the price of a commercial roof, from the climate to your choice of materials.
As an example, a 20,000 square foot commercial roof will usually cost between $3.50 and $7.50 per square foot in materials and labor to install. To get the right roofing system at the right price, here are a few things to consider:
- The size of your roof
- Roof access
- Installation choice
- Condition of your existing roof
- Type of insulation
- Roof penetrations
- Your Warranty
In the commercial roofing industry, 20,000 square feet can make the difference between spending or saving money. At 20,000 square feet, you can actually start saving money per square foot of roof. Other factors that can increase the cost of your roof are the logistics of moving equipment, debris removal and transportation of materials.
Your project can cost more money if your roof isn’t easily accessible by your roofing company or contractors. Some roofs can’t be walked on due to their condition, and some commercial roofs aren’t flat, making them more difficult to navigate. Height and distance can multiply the cost of your roof installation. If the roof is sloped, your contractors might be required to rent additional equipment so they can transport materials, walk safely on the roof or to hoist necessary crew and equipment.
Your Roof’s Current Condition
The condition of your existing roof can factor into the cost of your new single-ply membrane roof. Here are some additional costs that can occur when dealing with the existing roof before your new roof is installed.
- Clean and Prepare Existing Roof. When you have a solid roof that doesn’t require major modifications or corrections or removal, your roofing team will need to clean and prep the roof.
- Fastening Recovery Board. Recovery boards are commonly used to recover and improve the application surface. This process is used to cover joints and acts as a separator between the new roof and the existing roof.
- Stripping and Removal of Existing Roof. Since having more than two roofs isn’t permitted, your contractor will need to remove the existing roof before installing the new one. If your existing roof is unstable or damaged, your contractor will need to strip the existing roof to install a new working roof.
