First off, we are relatively small women and while we do a lot of home improvement projects ourselves, there's one thing we can't overcome and that is physical strength. We enlisted the help of our 6'4" athlete friend to carry these 5 gallon buckets up a ladder to our roof and even he was surprised at how heavy they were. From what we could tell in the store, these are even heavier than the white roof coat that's a step down in warranty (and I'm guessing thickness?)
Next we swept our roof twice over, with two different types of brooms as we don't have a pressure cleaner and have no idea how we'd get it onto the roof even if we did. We've been told since by a day laborer that that was a mistake... we should have washed it. I guess we'll see how things go in the years to come. Our roofer told us a third coat in 2-3 years is a good idea regardless.
We also chose an usually hot weekend to apply this product. Stupid, stupid, stupid. We will not do that for future re-applications of the product and encourage you to check the weather reports for freak jumps in temperature on the weekend you might plan to apply said product because IT IS HOT UP THERE and taking off clothes will leave those of us with light skin burnt (even with sunscreen). The white reflective material is intense and it feels like all 90 something percent not absorbing into your roof is now absorbing into you.
Okay, that was the worst of it... Application otherwise was relatively "easy" as others have said. The product rolls on smoothly with a roller on a pole. We used a 3/8" nap. No issues.
We'd had our roof serviced the month prior, so we didn't patch anything ourselves, but if you haven't had your roof serviced recently, you might want to follow the directions and patch vulnerable areas prior to applying.
The two of us applied two coats. The first was the most difficult and it took us around 6 hours to sweep and apply that coat on around maybe 1000 square feet. (It's hard to know the exact amount as we have a tile roof that covers a large portion of our home so we just applied the Envirowhite to the flat composition roll). The second coat went on much more easily. Maybe 2- 2.5 hours to apply that coat.
Temperature inside our house appeared to be about 4 degrees less in difference to outside when compared to the difference in temperature from inside to outside from the day before. Part of me thinks 4 degrees isn't a lot for how much work that was, but when you also keep in mind that this coating should theoretically extend the life of one's roof, help prevent leaks AND keep the cost of electricity for air conditioning down, I do believe it will be worth the time and money in the long run.
We haven't since had a weekend as hot as the one where we actually applied the coating, so it's hard to tell for sure, but we haven't used our air conditioner since application and it does appear to be cooler in our home. Not sure if that's mental or not yet. Only the summer will tell us for sure.
Mostly, I just wanted to show you some more photos, because I scoured the reviews looking for examples when I was trying to figure out whether or not to go through the hassle. FYI, if I were to do it all over again, I would... only on a much cooler weekend.

This Henry 687 product was recommended to me by a contractor friend to seal a very low sloped portion of my mother's house roof. The roof had been shingled recently but still leaked near the bottom of the slope. The area was about 100 square feet. I applied 3 coats over the course of one week, weather permitting. I used a roller with 1" nap for all 3 coats and put it on liberally. The first coat took about 1.80 gallons. Coats 2 and 3 took just under one gallon each. The product went on smoothly, covered well and dried and set up reasonably fast. A couple of days after the 3rd coat we got 1/2" rain one morning, then 3" torrential rains the next night into morning and there were no leaks at all where it had leaked before. I realize the proof will be in future year's durability, but so far I am pleased with the performance. My only negative comment is that it is fairly expensive ... $130 incl tax, but if it keeps the rain out it will be worth it.

The Henry Envirowhite Roof Coating is the premium roof coating product offered by Home Depot. It can be applied without a primer and is expected to last up to 12 years if applied in accordance with the instructions provided from Henry. I researched this product prior to purchase and it is highly rated compared to other roofing products. I also consulted with a roofing contractor who also recommended this product over the other products offered by Home Depot. There are other products available that are less expensive but multiple recoats over 10-12 years would be required. In the long run, this is the most economical choice for coating a roof.

Rated 5.0 out of 5.0 by toughchick Buy this for good coverage
We bought this product after buying the 5yr last time...it is much better to get 10 year or better if you live in a place like Arizona where the sun in intense...this one will probably last for several years.
Easy to apply as long as you clean and prep the roof first.

Rated 5.0 out of 5.0 by notHomer So far so great
Midway through applying this product to my rolled roof my attic (crawlspace) fan turned off. That was almost a week ago and it hasn't turned on since. Temps reached the low 90s today.
I applied two coats waiting 1 day between each. I applied the product to the sewer vent pipes as well.
It will take some time to get a accurate review of this product but so far I am pleased. Even in terms of aesthetics, my roof is better.
I have enough product to apply a third coat and just may do so.
My biggest complaint is availability of products from Henry in the New Jersey Home Depot locations. It appears that while the full line of products from Karnak are available in Home Depot stores, only 1 is available from Henry with other Henry products available for order and home delivery only.
Example: the Henry Asphalt Emulsion is available for in store purchase in every store in Pennsylvania, Florida, etc., but it is not even available for special order from the HD Pro Desk in New Jersey.

I purchased this product to apply to a rowhome roof in Baltimore City. The product might not be the best choice on all roofs in the city since it is so reflective and roof top decks are common. However, I used this to coat a neighbor's old bitumen roof that is disrepair, hoping to prolong the life of it a few years. 1 month in, the white membrane is intact and providing the reflectivity that we were looking for.
I think this is a very easy product to use. and we noticed a dramatic cooling of the third floor bedroom that typically is an issue in the older rowhomes with the stacking effect of heat transfer within the home.
