Denray Posted December 4, 2015 Report Posted December 4, 2015 How well does GACO roof coating hold up on mod bit?
Scottpat Posted December 5, 2015 Report Posted December 5, 2015 I have seen it use a few times and every single time it looked pretty good. If I recall it is something like 100% silicone so it is basically a waterproof sealant. The last time I found it on a building the roof was old but it had been on the roof for about 6 years and it was doing its job. I think it has some unreal warranty like 40 years or something like that.

kurt Posted December 5, 2015 Report Posted December 5, 2015 It's a tad more complicated than that. It will not provide the benefits described if other critical roof details are not satisfactory. All things being appropriate, it works pretty good, but it's not going to take a POS install and turn it into something else. It doesn't make up for lousy flashing details.
