Sashco Quart Clear Roof Sealant,14003

So I purchased 4 quart containers of this sealant a few years ago with intentions to do some repairs that were actually not necessary following some roof reconstruction. That said, this stuff sat in my shed for around 4-5 years before I had a chance to use it (not climate controlled - full swing of weather in the NE). I was afraid that like caulk tubes this very expensive purchase would be a loss but I was pleasantly surprised to find that all 4 containers stayed viable! I had a small leak in my roof SOMEWHERE that I could not pin down. I decided to just hit every possible infiltration point with this sealant and see (roof vents, waste line vents, a few cracked shingles, etc.). Well, one of the spots I hit must have been the leak point because months later there's no further leak evidence even following some pretty horrific rain storms. I am so happy with the results that I wanted to share a few things I learned while using this sealer. 1) I see a lot of people recommend foam brushes for this stuff, but I would counsel getting short utility paint brushes instead. My asphalt shingle roof would have shredded the foam brushes and the traditional bristles of the utility brushes I purchased let me really get into the cracks with the sealant. Also - the bristles are a bit stiffer than many foam brushes - good for getting the last of the sealant out of the jar, especially as it starts to cure. I used a 2" wide brush (with 1" long bristles) which just fit into the mouth of the quart jar. I got a box of these things for peanuts a long while ago and still haven't run out of them. 2) A note about the curing... some other reviewers mentioned getting gallon containers instead of the quart size containers. Do this ONLY if you are going to use this stuff all at once and relatively quickly. I was very careful to recap my quart jar as I moved about the roof and I still barely got to the bottom of the container before it started to gel up to the point it became unusable. Unless you have a big project, get a bunch of quart size jars so that the most you will use/lose per job is one quart. Plan your job ahead of time so that you will spend the least amount of time after jar-open. 3) Plan to lose what you don't use. I carefully re-capped what little I had left in the last quart jar I was using - even did the "breathe into the jar for CO2 layer" trick and the stuff still completely cured within hours. Once air gets into the jar the timer starts ticking. 4) Be careful cleaning up. I got this on my extension ladder, jeans, shirt, shoes, etc. I was wearing work clothes and work gloves so no problem there, but you would NOT want to get this on anything you care about. One unexpected bonus - the work gloves I was wearing now have a water resistant side - the sealant coated the palms and fingers of the work gloves and they are still flexible and workable! 5) Be aware that this sealant is somewhat shiny when cured - so if your roof is visible from ground level, the repair patches will be noticeable if you're looking. It's not "ice in the sun" shiny, but on an asphalt roof it stands out. I don't care because anything was worth nailing that leak, but it's something to take into consideration. The net sum is that this sealant really works, sticks to anything and everything, and is still pliable and well adhered almost a year later after being applied to a swept but weathered roof in full exposure to the elements. I can only hope that it lasts until it's time to re-shingle the roof again.

I have purchased this product several times over the years and it is simply the best at sealing small to medium size roof leaks or points of water intrusion. The cost of professional repairs has literally, "gone through the roof" I several years ago I had a skylight leak. The roofer wanted to replace the skylight and 2 or 3 ft perimeter of the roof around the skylight for $5,000. I used half a tub of this product and still not a drop from the previous leak after almost 3 years. This time around, I noted some water intrusion coming from a space between three architectural posts that connect the garage to the house (60 year old single level adobe style home) the posts had some dry rot after 60 years and this caused a 1/4 inch separation between the posts and the exterior wall where in heavy rain, water would intrude between the wall. A carpenter wanted $10k to replace the posts and perform some dry wall repair. I simply sealed the gap between the post and the exterior wall and it has been water tight through several storms. Finally, the first time I used this product 4 or so years ago, I had a more serious leak that would require about 15% of the roof to be replaced. This product sealed out most of the leak until the roofers could replace the bad section. Some people seem to like to plow every cent they earn into their home. I have friends and family that have 0 in retirement savings, 0 contributed to fully matched 401K, anytime anything goes slightly wrong with their home they immediately choose the most expensive solution to replace the item. A family member recently had a small leak around some molding at a second floor spare bedroom. Her roof is only around 12 years old and in very good shape. She took out financing and spent $29k for a new roof on a 1400 square ft house. If something really needs to be replaced to prevent serious further damage or is a safety risk, by all means replace it. However, for a small leak this product will buy several years time or my simply fix the problem all together.

We tried a few different sealants to patch roof on our trailer slide. This is the only one that did the job. Works exceptionally well.

This stuff is great - we had a leaky Suntuf roof and used this to seal the joints. Easy to put on, dried clear so you can't see it and now we're leak free! Except for the spot I missed, but that's my fault and not the product. =)

This was recommended to me by a contractor when I needed to waterproof a roof from which shingles had blown off. It lasts a long time and is clear so it is not obvious. It has got the roof through periods when it is too wet, cold or slippery to repair.

Takes awhile to cure but seems to do a good job.

Did exactly what we needed it to do until we could replace our roof. A gooey mess but very useful for many applications 👌
