Ratings may include incentivized customer reviews.
The roof coating is generally effective at sealing and protecting roofs, with many users reporting it stopped leaks and sealed cracks. However, the product can be challenging to mix thoroughly, and the application process can be messy. While most customers were satisfied with the results, some experienced persistent leaks after using the product.
Customer review summary generated by AI, including incentivized reviews.Good stuff!
I live in an old old mobile home. The roof is and had been leaking for years. A roof inspection my be found many small to medium holes rusted through along with some of the seams of the metal roof were cracked and no doubt leaking. All the flashing around the vents in the roof from the bathroom and kitchen were peeling up and no doubt leaking as well. I got two buckets of this and let it sit outside on a sunny day upside down, then the next day I flipped it over right side up and went to wor...
DIY roof project
I simply could not afford the $5,000 roof repair from a area contractor. It's a third floor roof with a very high pitch at 1,980 ft. After reviewing his scope of work I found the product he intended to use... the same product available at my local Lowe's so, not knowing anything about roofing I began the process of cleaning, scraping the loose paint and following the instructions of the material. I had no issues are complaints with the finish. I will add that the material is incredibly slipp...
Paint thinner!!
I just spread two 5 gallon buckets of this stuff on the roof of a mobile home. All these reviews were helpful so I want to add my 2 cents. Mixing...I bought a long steel paddle mixer from Menards n put in my plug in heavy drill. No battery powered drills for this. Plug it in n use a heavy duty paddle mixer. Still takes 10 minutes or so of non stop mixing to get it ready. The alumninum is in a sludge type base at the bottom of the bucket. Take your time mixing at all levels. Top middle n bottom. ...
3rd or fourth time I have used it. Good product
I think it is generally a good product. Does as stated. Adds life to roof. The roofer said to put silver seal on and the the roof will outlast you. Thus far it has done pretty well. It is a flatish 3600 sf roof that was installed in 2004. We had one leak this past winter, but we think it is a flashing issue an took care of it with the patch and another coat of Silver Seal. I have gone 2-3 years between applications and just do one coat. This year the How To Instructions on the Lowes websi...
Thanks for choosing Black Jack Silver-Seal 300.

Works well for my application!
I have two galvanized metal tops on my free standing chimneys that were in need of resurfacing. The whole tops were very rusty. First I rough sanded them (not down to the metal). I wiped them with an old cloth and put on two coats of Rustoleum primer for very rusty metal. It took less than a quart. After 24 hours I applied a coat of Black Jack and it looks great. Now about the Black Jack. I had used this product years ago on a metal roof so I knew what to expect. First, don't wear any cl...

Great stuff but WEAR GLOVES! Gasoline 2 remove
A few thoughts: **You don't need a contractor, you got this! 1) This stuff takes a while to mix, so I would recommend buying a paddle mixer. It's thick, and would be rather difficult to turn over by hand. 2) I got this stuff all over me. Regardless of how careful you are, it will inevitably splatter. I would strongly suggest using heavy duty gloves, wearing long pants, and a long, thick shirt-all of which you will throw away when finished. I don't care if it's 100 degrees outside, this stuff is ...
Don't take store workers word's
I went in there to get stuff to patch up a smoke stack hole and catch up some other leaks on my mobile home roof I am on a fixed income it's very hard to actually get the things that I need and getting someone to do the work and being disabled doesn't help much but a guy in the store that works there told us to get this item and it does not work I have rain pouring in my place floor is messed up now ceiling is caving in I really wanted to get the tar cuz I heard that work but know this guy worki...
So sorry to hear about your leaks Marykaye. The product you referenced is a coating that would be applied after repairs are made.
Be Peepared
The key to this product is to be prepared. First buy at drill powered stirrer or you will be worn out before you start. Second buy sacrificial clothes...overalls and long sleeve t shirt and SHOES...to wear. Next buy a box of latex gloves and put them on first. Finally be prepared to strip and change unless you want sealer in truck, chair or anywhere else. Forget paint pan, stir and pour into small pail. Pour paint on roofing at peak and get ready to mop down slope. Roller and mop work bes...

Easy and Easy!!
I compared pretty much every roof coat you can possible imagine and decided on this one. For me it wasn't a matter of the best, it was the easiest that works well. My 1/12 pitch roof isn't to strong, where a 150lb person walks on it and it flexes. So i didn't feel comfortable to do it and my buddy said he would do it. I picked this one becasue anything better requires a base coat and then 2 coats of the regular product and all has to be done in 1 day. Since i wasn't going to be doing it i chose ...
No more leaking roof!
I have a flat tin roof over my 12' x 35' porch. Every time it rains hard water gets in the joints between the sheets of tin and leaks all over. It only took 1 coat of silver seal 300 to fix the problem. After letting it cure out for a week I went ahead and put another coat on it mainly to use up the rest of the product. After 2 coats I still had about a gallon left so I put it on an out building that also has a tin roof. I read the reviews on having a hard time stirring it up but the day before ...
