Tpo Vs Edpm Rv Roofing

Tpo is a versatile membrane and can be installed in a variety of ways including mechanically attached adhered and with the rhinobond system.

It is a synthetic rubber derived from oil and natural gas ethylene propylene. Mechanical installation for optimum roof security contractors use the mechanically attached system when installing tpo on flat roofs. Tpo is a blend of polypropylene and ethylene propylene rubber. Tpo also has a somewhat higher resistance to punctures than epdm.

They achieve this with fastening plates to secure the roofing material. Tpo is much lighter and easier to install but epdm is a whole lot cheaper and lasts longer. One advantage tpo roofing has over epdm roofing is enhanced durability. Tpo however requires more maintenance as you need to treat its seams with an adhesive causing it to be prone to coming apart.

Epdm has a dark surface which in summer conditions will absorb heat forcing cooling systems to work overtime whereas tpo roofing reflects sunlight allowing commercial air conditioners to work more efficiently.
