Applies easy!
[This review was collected as part of a promotion.] Very happy with Loctite PL Roof & Flashing Polyurethane. We had a new roof put on 6 years ago, and the roofers told us to make sure we kept up on maintenance with the flashings. My husband checks the roof every year and keeps things sealed. Loctite works fabulous. He applied it with a caulk gun for easier control. It was easy to apply, flexible, high quality and durable. It withstands the summer heat right now, and I have confidence it will be just as great in other elements. Loctite is also paintable, although, we did not need to do that, but it might be worth mentioning for those interested. I highly recommend this- and keep up on those flashings!

This was relatively easy to use. The sealant is extremely messy so wear gloves. It "glued" the shingles to each other sufficiently as far as I could determine. I would like to review again after hurricanes but there is no way to do that.

I needed something to seal a few roof vents, and this was recommended. So I tried it, and it worked great. I applied it over existing mastic, I know that's not recommended, but it worked. The trick is to cover the entire area, not just a spot. It's a bit hard to get out of the tube due to it's low viscosity, make sure it is warm before using. It is super tacky and immediately sticks to anything it touches, which makes it easy to apply. It spreads pretty well too, using a gloved finger it was easy to seal the vents. Got some on my fingers but it comes off easily with coconut oil or other vegetable oil. The tubes don't look like the picture, see my pic for the actual product label.

Loctite PL Roof and Flashing Sealant: A Reliable D
[This review was collected as part of a promotion.] I recently had the opportunity to use Loctite PL Roof and Flashing Polyurethane Sealant for a DIY roofing project, and I must say I'm quite impressed with its performance. As a homeowner who values a leak-free roof, finding a reliable sealant is crucial, and Loctite PL did not disappoint.
The application of the sealant was straightforward, thanks to its user-friendly design. The nozzle allowed for precise application, and the consistency of the sealant was just right – not too thick, making it easy to spread, yet not so runny that it became messy.
One of the standout features of this sealant is its exceptional adhesion. It formed a strong bond with a variety of surfaces, including asphalt shingles, metal flashing, and even concrete. This versatility made it an excellent choice for the multiple surfaces I needed to address in my roofing project.
I particularly appreciate the weather-resistant properties of Loctite PL. Living in an area with diverse weather conditions, I needed a sealant that could withstand everything from scorching sun to heavy rain. This product delivered on its promise, providing a durable barrier against the elements.
