Cofair QR36 Quick Roof Pro Aluminum 36" x 33.5'

I used this on the metal roof of a container, a surface identical to any metal roof. It turned a solid drip into a steady drip, does NOT eliminate leaks entirely on metal.It went on beautifully. I used a roller to apply it perfectly. It formed to the roof with such perfection, I was impressed how it compressed easily and the edges were nice and sealed ... it looked so good, I was so confident of the adhesion, I was excited ... wondered why I hadn't found it before!I layered it as instructed, overlaid it as instructed, applied it as instructed. I did the prep for hours to be sure it was perfect, cleaned it of every possible contaminant that might impair adhesion or encumber sealing. I used a grinder to effectively "sand" the metal as you might wood, to give it a nice clean surface to bond to. I ended up with a smooth, and easy surface to apply to and, even applied it within the temperature range instructed. I was so happy I had found the perfect solution, I went to bed finally happy I had solved the problem!THEN ... came a heavy rain.I woke up, walked inside the container, ready to say, "HA! Take that rain! I WIN!" .... and I had to put a bucket under the patch to catch the drips.Make a long story short ... no matter what you do with this product, it does not work on metal. I patched 6 different areas the same way (took almost 3 hours to prep, clean, dry, prep and apply) ... 5 of the 6 leaked.It's SO FRUSTRATING to WASTE your time on something ... time you will never get back. Now I have to start all over with something else ... SO disappointing and time consuming.I REALLY had hope in this product ... was disappointed. I hate to write bad reviews as most of them are just people with an ax to grind ... but this is just a factual account of profound disappointment.

I purchased this to patch some holes that had rusted through some old down spouts and attached piping. At some point I plan to replace the entire system, but for the time being wanted a temporary fix for the water that was leaking through the holes and creating puddles around the house.It's only been a few weeks but thus far the patches have held up really well. There is no water whatsoever leaking from the holes that used to exist (ranging as large as a nickel in size) during some of the strong downpours we've had recently.I sanded down the paint and rust around the holes and then cut a piece of this for both the exterior and interior (where I could reach). It was a fairly simple process.I only give four stars because the backing and tape tend to separate easily, even just unrolling the product. It doesn't seem to affect the adhesive but does make it more difficult to cut to size.

This stuff is amazing. There is no other words to describe it- worth every cent. The tar material on the back makes it able to stick to almost anything. I put a tin roof on my patio and this seal a crack between the chimney and roof with ease (sticking to both the brick and sheet metal). I would buy again- and probably will in the future.

This stuff works GREAT. I have used it for patching around flashing, at transition to metal roofing and similar places, with some of the repairs holding up after 10 years. I just used this last roll to seal gap between a new galvanized chimney cap and my chimney flue lining - stuck well to both the galvanizing and clay flue liner.

I bought this as an unconventional use to silence my computer tower. LOL It worked as best it could without me covering the vents. But what I loved about this stuff is the ease of use working with this product. It was quite forgiving, easy to cut with normal scissors, and smelled pretty decent. I don't know what to do with the rest of it that I didn't use, but it feels quite crafty and fun to think of all the ways I it could be used. Thanks for this awesome product!

It works but I'm not sure of its longevity. I applied it on my shingled roof which had a small leak. The insurance inspector said that I have a small crack on my chimney which caused the rain to trickle down inside. So I applied this around the chimney hoping that would take care of any leak. After a week long heavy rain, there was no leak at all. I just hope it would last, but I'm ordering another roll and patched it some more.

Sealed my roof and stucco perfectly. I used it as flashing instead of opting to have the expensive repair of ripping out a ton of stucco and shingles. You can paint over it to have it not stick out so much if you do not like the silver color. Works great.

Bought this product to see if it would repair the flashing around my roof jacks. It's been on now for over 2 months and it's holding fine both to the lead flashing and the roofing shingles. I don't know how long it'll last but right now it's doing great.

Gave it to my son who has exterior house cleaning (gutters, windows, roofs etc) business. He says its great stuff for minor gutter repairs. Very strong adhesive and easy to use. Combines this with a rubber spray for to make any seam leakproof.

dessus d,une remise en tôle. efficace mais a utiliser sur une tôle chaude.

Very satisfied, it very easy to apply.

Exactement ce que je recherchais...

Perfect for sound deadening my 1968 VW bug. So many used for this product!
