That white film is extremely easy to damage with cleaning products that contain petroleum distillates or citric acid. The "tiny cracks" in your photo are "classis distillate damage"....

That said, 5 or 6 years is about the time frame when EPDM roofs that have been "essentially ignored" start to show signs of damage. While I'm not suggesting that your roof has been "ignored" it probably would be in better condition, had it not been washed with car wash products.

At this point, you can "more or less" consider that the "cosmetic condition of your roof" is gone. The base membrane may or may not be damaged and have the same cracks. Chances are it is still in relatively good condition and what you see is more "cosmetic than physical" deterioration.

You can, if you choose, reseal the roof with DICOR 2 part sealant. That will restore the cosmetic appearance, fill the cracks and "recondition" your roof. You should see a remarkable appearance improvement for several years. Applying the 2 part sealant is not an easy task and it takes substantial "effort" to apply. It's not technically difficult, just labor intensive.

If the appearance bothers you, reseal, if you don't climb on your roof to look down at it and there's no "nosey neighbors with 2 story houses", then clean it well with Dawn and Clorox, let it dry and apply a good, liberal coat of Aerospace 303 and go camping (after the obligatory adult beverage break, of course).....

Are the TPO roofs not a susceptible to damage from car wash products? Do they require any routine maintenance besides cleaning?

Thanks
