A lot depends on condition of EPDM and your budget. If you're a die hard DIY'er, installing a new EPDM membrane is not that difficult and should last many years. Cost would vary by area and supplier but $300 is probably a good target for DIY.
Coatings are just that, a paint basically, that is applied to the surface and will change appearance and offer some UV protection. I sprayed my aluminum roof with an acrylic elastomeric roof paint and it is holding up well at five years (stored outside). I used White and it lowered the cabin temps by 10f. Typical elastomeric roof paints cost in the neighborhood of $30-> $50/ gallon. Do two coats.
How many EPDM rubber roofs have YOU replaced? $300 for a DIY? What a Crock. You have to remove the roof top appliances. You then replace the seals on the AC units. You replace the Plumbing vents stacks. You usually replace the roof top vent covers as they are usually UV degraded. You have butyl tape and Dicor sealant. You have the rubber membrane and the adhesive. You also have to install ALL NEW WOOD DECKING. The EPDM will not stick to the old EPDW glue after you remove the EPDM. Parts alone will run over $700 if you find good deals on the EPDM. Doug
