Has anyone tried painting their rubber roof to keep the house cool?
I did read the Breaktime posts about EPDMcoatings etc but that is overkill for what I need. My black rubber roof is already water-tight – I just want to reflect the sunlight.
Also I don’t care if the white paint only lasts the summer – all the better to melt off the winter snow. By the way, my roof slope is nearly flat – maybe 5 degrees (triple decker in Boston)

for other's info - EPDM can be had in white to begin with.
I knowthere is a paint specially for EPDM but don't remember what it is.
But almost any latex paint will work. I recall a spot where somebody spilled some and half azz wiped it. That spot was still doing fine seven years later!

What about that Sno Seal or whatever it's called? See it at lowes etc, along with roof patching stuff. White elastomeric sealer.
It'll work. Most EPDM resellers also sell a white coating product.http://grantlogan.net/
Check it carefully. The stuf I used to genericly call sno-seal had an asphalt base, whih will eat EPDM for lunch.Elastomeric is a latex tho, I believe, which is OK

clean it first.... then most paints will stick... I've played with a few samples of torchdown just to see what would happen... all are still white... don't know if you had any standing water what would happen...
my plan is.... once i run up on a deal... is to paint it with parking lot stripe paint... i just need to luck up on a 55gal drum oh yeah i want the reflective stuff... if it will hold up on the road on asphalt... i kinda think it'd last on your/my roof

Modified torch down is more compatable with oil base products than EPDMs are

Snow Seal needs a primer coat to he put down first, then a layer of Snow seal. Otherwise if snow seal is put down, it will peel off in a year or two, as it's latex based.

The reflective property of white cannot be overrated.
I once put up some greenhouse conduit bows with 3year monsanto transparent greenhouse poly for a covering.
Even with venting the second the sun came out it become a cooker in there.
I took regular latex exterior white paint in an airless sprayer and coated the outside of the plastic and it was remarkable how much heat immediately dissipated.
Worked good and stayed stuck till I covered it again 3 or 4 years later with another layer of plastic. Been about 3 more years and the white is still sticking well to that first layer of plastic yet.
