Customer Questions & Answers

How much do I need

My roof Is 16 feet wide By 6 2 feet long
Asked by: Bubba
Per the label, Henry's 107 should be applied at the rate of 3 Gallon per square (where a square is 100 square foot). Using this coverage rate, a 4.75 gallon pail will cover 258 sq. ft. That's for a single coat. As noted by others, Bubba's 16' x 6.2' roof is 99 sq. ft. He can expect to get two full coats from one pail.

Which one is best for ponding water proof on roof, 107 or 203?

I'm going to do roof coating to prevent water leakage. Roof style is flat so that leakage comes from low level where remain as ponding water during rainy. Please advise which one is best to use. Thank you.
Asked by: Thomas
The best product to use is our Henry 887 Tropi-Cool 100% Silicone Roof Coating. It has a Lifetime Warranty and is Lifetime Ponding Water Resistant. You could use the Henry 107 Asphalt Emulsion as long as you coat over it with Henry 687 Enviro-White or Henry 587 Dura-Brite. With the second option, the product is ponding water resistant for up to 48 hours. For more info, please check out or contact our product support at 800-486-1278.

4.75-Gal. 107 Asphalt Emulsion is rated 3.9 out of 5 by 15.
Rated 5 out of 5 by from Good product if you know how to use it. I fixed and overhaul a few flat roofs in Arizona. 1) Fix all the softspots first 2) clean, mob using TSP cleaner and rinse 3) Apply one thick coat or 2 coat at bad areas and let dry for a week 4) This is just a base coat. so I applied silver coating 5) It usually hold up at least 5 years. You can apply silver coating in some areas for touch up and maintenance. 6) One of the reviewer (Leon) coated the whole roof with this but probably did not use any coating. The black coating will crack under the sun. I highly recommend this base coating as a base coat only with silver coating coating on top.

Rated 5 out of 5 by from Worked for leaky roof I used this product to repair a leaky rubberized asphalt roll roof. It is a flat roof with little pitch and minor ponding of water. I first tried to fill and level the low spots with the solvent based fibered asphalt and still had leaks. I then used this water based product as a primer and bsae for #587 white roof paint and did the whole roof, I reinforced with the recomended polyester roofing fabric and top coated with two coats of the paint. After six months and quite a few thunder storms and heavy rains I am confident this roof will last many years. No more leaks at all. As an added benefit this system reduces interior and roof temperatures.

Rated 5 out of 5 by from Works great when used as directed. Please read the directions. Depending on the weather, it may take several days to dry and become waterproof. I used it during the warm, dry season. A week later, it was set and I painted over it with white roofing paint. It’s been a year now and its still in great shape. I'm going back to this product to do more repairs. BTW, it cleans up with water; no solvents needed.

Rated 5 out of 5 by from Multiple Uses Product I was looking for something to coat my fence posts so that the wood wouldn't deteriorate as quickly. I found this in Home Depot. It coated easily. I used this product for my foundation wall also. I used a thick brush to apply.

Rated 5 out of 5 by from This product works as described. Saved us!! We were leasing a house and the downstairs flooded a couple of times and we were desperate!! Found product at Home Depot and talked with a contractor while I was checking out and he confirmed the superiority of this product. We had another flooding incident but the water did not come in where we had applied to the floor and 1 foot up the walls. Came into another room. Easy to apply and it WORKS!! We are presently moving again and this time leasing an old farmhouse and the owner has no idea what to do with basement. I do and I am sealing before moving in!!
