Cost Breakdown by TPO Roofing
TPO Membrane Costs
The primary cost associated with TPO roofing is the membrane itself. Depending on the thickness and type of TPO membrane selected, prices can vary:
TPO Membrane Thickness | Average Cost per Square Foot |
40 mil | $1.50 – $2.80 |
50 mil | $2.80 – $4.00 |
60 mil | $4.00 – $6.00 |
The thickness of the membrane directly impacts its durability and longevity, with thicker membranes generally offering better performance and extended lifespans. Contractors should assess the specific needs of the project when selecting the appropriate thickness.
Insulation Costs
Incorporating insulation into a TPO roofing system can enhance energy efficiency and reduce heating and cooling costs. The cost of insulation can range from $1.00 to $3.00 per square foot, depending on the type and R-value chosen.
