To lay rubber roofing, you need to prepare your roof deck, install underlayment, measure and cut the rubber membrane, and seal all seams and edges with special adhesive or tape. Rubber roofing, also called EPDM or TPO, is a popular choice for flat roofs because it lasts a long time and does not cost too much to install. According to RubyHome (2025), flat roofing materials like rubber range from $5.50 to $7.50 per square foot with installation included. Most homeowners can expect to pay between $5,868 and $13,217 for a full roof replacement. The good news is that rubber roofing is one of the easiest materials to install yourself if you follow the steps carefully.
What Is the Best Surface for Rubber Roofing?
The best surface for rubber roofing is a clean, dry, and flat roof deck. Your deck should be made of plywood, concrete, or metal. Remove any old roofing, nails, and debris before you start.
Make sure the surface is level. Any bumps or holes will cause problems later. Sand down rough spots and fill in gaps with roofing cement.

How Do You Measure and Cut Rubber Membrane?
Measure your entire roof from edge to edge. Add 6 inches to each side for overlap. Cut the rubber membrane to size using a sharp utility knife.
Lay out the rubber slowly. Do not rush this step. According to industry data, commercial roofers use single-ply systems like EPDM and TPO on 91% of flat roofs because these materials are easy to cut and fit.
What Sealing Method Works Best?
You have two choices for sealing rubber roofing: adhesive or tape. Adhesive is the traditional method and creates a very strong bond. Tape is faster and easier for small repairs.
For seams, use a special rubber roof sealant or tape made for EPDM. Apply sealant to all edges, corners, and seams. According to RubyHome (2025), roof installation costs range from $4 to $40 per square foot depending on the material and method. Press down hard and let the sealant dry for 24 hours before walking on the roof.
| Sealing Method | Time to Dry | Best For |
|---|---|---|
| Adhesive | 24 hours | New full roof |
| Tape | 12 hours | Repairs and patches |
How Long Will Rubber Roofing Last?
Rubber roofing lasts 40 to 50 years if installed correctly. According to RubyHome (2025), rubber and flat roofing materials typically last between 40 and 50 years, making them one of the best long-term choices. Regular maintenance like cleaning gutters and removing debris helps extend the lifespan. Check your rubber roof twice a year for cracks, tears, or loose seams.
The average roof in the U.S. is replaced at just over 19 years old, but rubber roofs can last much longer. If you take care of your rubber roof, you will get many years of protection from leaks and weather damage.
