[This review was collected as part of a promotion.] I have used acrylic latex paint including Behr on asphalt shingles without primer and the results were fine even 15 years after painting the roof white so see no need for a primer. My experience is that acrylic latex paint adheres very well to asphalt shingles and in addition, acts to hold the gravel to the shingle. Why does Behr recommend a primer? I have also thinned the first coat substantially to ensure that it it seeped between shingles since I have found the paint acts as an additional bond between shingles. Overall, I have found that painting shingles will add substantial life to them.

      Garbage product
      This product is terrible. It cannot withstand freezing temperatures as it says it can. My roof (metal roof). was done under a year ago and it’s already peeling ALL off and has to be redone. I highly do not recommend this product to anyone.
      Response from Joanne, Behr Customer CareMar 4, 2022
      Hi DaniV, thank you for your review. I’m so sorry the paint is peeling off your metal roof after a year. To fix this, I recommend removing any loose paint, sanding smooth any edges, cleaning the surface, letting it dry, spot priming any bare metal with our Multi-Surface Primer No. 436, then touching up and recoating with our roof paint. Customer satisfaction is very important to us, and we appreciate your feedback. I’ll reach out to you directly to assist you with this further. Thank you again for taking the time to share your experience with us, and I hope to hear from you soon! -Joni

              Great Idea! We will use this on our future project
              [This review was collected as part of a promotion.] We did not get the coverage listed on the can of 250-450 square feet per gallon. We currently used 18 gallons for a 2400 square foot roof and may need 5 gallons more using an roller for extra course surfaces. Maybe if the roof was sprayed we could get better coverage rates. The current roof was in very poor condition and was a light tan color and we used a black Behr paint. The finished roof looks beautiful. It looks brand new. Behr claims it will not extend the life of the roof or prevent leaks, but after applying it, I think is has to extend the life of the roof and fill areas that might leak. It takes some practice to get a nice even painted surface. Using different techniques will generate a different finish. We tried a brush, different rollers and will be using a sprayer. Different painters got different results. We got the best results painting in horizontal rows following the shingle tiles. Areas where we painted two coats look really nice.

                    Response from BehrApr 10, 2018
                    Hi, thank you for your feedback. I'm sorry to hear the finishing color on your painted roof was not what you were expecting. To verify if the color was mixed correctly, we’d suggest checking that the physical color swatch matches the paint dab on the lid of your paint can. If they match, the paint was properly mixed, and the color is correct. And in cases like this, the best solution would be to recoat in a different color. If the swatch doesn’t match the dab on your can’s lid, the color was incorrectly mixed. And we’d suggest recoating with new paint tinted to the correct color. Please keep in mind that different lighting will affect how a color looks and that our online color palette display may vary slightly from the actual colors due to color variances in monitor settings. To ensure you’re getting the right color for the area you are planning on painting, we recommend picking up a sample of the color and applying it first before purchasing your paint. Customer satisfaction is important to us. So, don't hesitate to contact us directly if you need further assistance. Have a wonderful day! –Joanna Behr
