How Much Does a CSPE Roof Cost?
Last Updated: January 25, 2022
Chlorosulfonated Polyethylene (CSPE) is a type of synthetic rubber used for flat and low-slope roofing. CSPE roofing is sometimes referred to as Hypalon, the trademark for a CSPE manufactured by DuPont. DuPont was the first company to manufacture CSPE, and Hypalon is a common name for CSPE roofing membranes despite the fact that DuPont no longer manufacturers Hypalon roofing. Other companies do still manufacture CSPE resin, however, which is fortunate, because it is one of the best single-ply roofing membranes available today.

CSPE Roofing Considerations #
When installing CSPE rubber roofing membrane on your home, keep the following considerations in mind:
- Thickness: CSPE single-ply rubber roofing is typically sold in thicknesses of 36, 45, and 60 millimeters, although it's possible to special order thicker membranes.
- Color: Available colors for CSPE flat roofing are black, white, and gray. Note that white and light-gray roofing can help you to drastically reduce cooling costs by deflecting heat and light.
- Installation Method: A CSPE rubber roof can be mechanically attached, fully adhered, or ballasted.
Be sure to discuss these factors with an experienced roofing contractor if you have any questions about them. Depending on the climate where you live and the design of your home, certain types of CSPE rubber roofing membrane installed in a particular way may provide the best flat roof solution.
The Benefits of CSPE Roofing #
CSPE rubber roof membranes are some of the best you can buy for reasons that include the following:
- Seamless: Individual panels or sheets of CSPE roofing are either hot air welded or vulcanized with special adhesive solvents. Whichever method is used, the result is the same: the individual polymer components cross-link to form a single, highly stable, strong, and tough rubber roofing membrane.
- Protection: A CSPE rubber roof provides excellent protection against UV and Ozone exposure, organic and inorganic chemicals, fire, and all types of weather. It even retains flexibility in freezing and thawing conditions.
- Variety of Uses: CSPE is not only an excellent flat roofing material for your home roof, but can also be used on shed roofing, dormers, chimney crickets, and to reline old fashioned tin box gutters.
- Long-Term Value: Rubber membranes are not the cheapest flat roofing material, but when you consider that CSPE roofs often come with a warranty of 20 to 30 years, are much less prone to failure than a traditional built up roof, and can slash your energy bills, it's clear that installation cost doesn't tell the whole pricing story.
CSPE Roofing Average Costs #
Due to factors that include your location, the complexity of the installation, and the materials used, the actual cost of a CSPE roof may vary.
- CSPE roofing costs $2.50 to $4.50 per square foot, assuming that the original roof does not need to be removed and disposed of. If it does, the total cost might increase to $4.00 to $7.00 per square foot. Assuming a typical roof size of 1,500 square feet, you're looking at a total installed cost of approximately $4,000 to $11,000.
- Adding a cool roof coating, sprayed or rolled on paint-like materials that improves roofing durability and solar reflectance, costs around $1 per square foot (or $1,500 for the entire roof).
