Great Stuff!
I have a flat roof over my screened-in porch and the intense heat of the sun here in southern Louisiana, causes the coating to darken and deteriorate over the years. My purpose in recoating the roof is to make it last longer. I've recoated it I think three times in the past 25 years (a new surface was applied 35 years ago) with other, cheaper coatings but this is the first time I've used GAF Roof Mate Top Coat. I just finished putting down the first of two coats with a roller and my initial impression is that GAF Roof Mate Top Coat is superior to the cheaper brands in terms of its smooth consistency and ease of application. Time will tell if it indeed will last longer than the cheaper brands.

    Coats Well, Easy to Apply.
    The Roof mate Top Coat is the capstone for my roofing projects. I had three asphalt shingle roofs, one metal roof, and one TPO membrane roof I had prepped for this final application. I rolled on each application with a 1-1/2" thick roller. It went on easily and covered the primed base coat surfaces well, The base coat from Roof Mate did a great job sealing small cracks and this will give an extra assurance they will be well sealed. The video and pictures show the roofs with the first coating. As you can see, one coat did a great job covering the surfaces, The five-gallon pail covered the roofs shown in the video and the TPO membrane (14' travel trailer). I plan on applying a second coat next weekend. Great roofing system when all Roof Mate products are used for your project.

      Had an aluminum sun-porch/3-season room installed 2 years ago and the seam tape they used was horrible - constant leaks. Applied the Roof Mate 4" wide tape, then painted the entire roof with the Top Coat. Problem solved.

      Costly but this product is the thing for old roofs that have trouble spots but not reroof time yet. Way cheaper than new. I ran it thicker, not worried about square footage. The shingles are stuck down like cast iron. Strong stuff.

      Seems to Be a Great Product
      I used the 15 year GAF Top Coat on the flat roof over the office and den of my home. It was a 3-day process. I used a blower to remove loose dirt and dust. Then I washed the roof with dish detergent and water. I rinsed it well and allowed the roof to dry for 24 hours...that did not take long in the 105 degree heat we have had here in Southern California. The roof is a 11-year-old hot mopped rolled composition roof and had been coated before with a different elastomeric product by a roofer in around 2014, so I did not use a base coat. On day two I used a brush to apply coating around and on exposed heating/air conditioning ducts. Then I rolled on the first coat of the product. It went on very easily and the result was a clean, bright, reflective finish. The third day I applied a 2nd coat just as I had the day before. The roof was in very good shape and with this GAF 15 year top coat, I think I will get several more years of service from this roof. I am also proud to have done the job myself because I paid close attention to the key details outlined in the product instructions. Pros: Easy to use, great instructions, easy clean-up, GREAT reviews. Con: Will take 3 to 4 days, but likely worth the time

        I used this to paint the chipping roof of my van. I applied using a foam roller and 4 coats covered a full size roof with about 1/4 of paint remaining. Left a spot unpainted and there was a 5F degree temp difference on a partly cloudy day! Only negative was the dark primer was difficult to cover up. If you have a light primer it should cover it nicely. They white is blinding to look at in the direct sun!

        Works well on metal roofs
        GAF Top Coat went on very nicely and looks great. Very pleased. On another metal roof I used Acrylabs 2100 Finish Coat. Big mistake. The coating had hundreds of small to large bubbles embedded in it. Acrylabs suggested I cut out the larger bubbles and apply more of their product to those areas. Really? Go with GAF Top Coat.

          It is typical to add shelf life to all coating and flashing products due to their chemical nature. If stored in ideal conditions, as should be the case on the shelf inside a Home Depot store, these products may remain usable beyond their shelf life. To verify this, mix the product well and apply a small test sample. Let the product cure overnight. If then the coating is solid, elastomeric, and dry throughout, the product is still fit for use. gaf

          I have used this on the roof of my old huntin' and fishin' trailer and it really does a nice job sealing things up. I cleaned the roof off and then rolled this stuff on. Not hard and works great.

          I used this on a travel trailer roof which had a previous coating on the surface. I did 3 coats over a 2 day period. It becomes a reflective rubbery coating. It seemed to adhere really well to what was like a hypalon impregnated top coating on the roof. I used 3.5 gallons.
