My small flat roof (South Florida) was re-roofed 3 years ago with GAF cap sheet. There is evidence of ponding, but the question I don’t know how to answer is how long the ponding remains.
It is time to do some maintenance on the roof and it has been suggested to coat it to extend its life. I am fine with doing that but have a choice to make and not sure of the pluses and minuses between the two.
#1 Original roofer (5 years left on warranty)
Prep and coat with two coats of GAF TopCoat. Not sure which type, but definitely reflective.
#2 Other roofers
Recommended the Gaco S2000 system. One roofer is willing to provide a 5 year warranty for the job as long as I pay a nominal fee for an annual inspection.
What are the pluses and minuses for GAF TopCoat versus Gaco S2000? Any advice is welcome.
I think re-roofing is out of the question as long as I have a roofer warranty for leaks. The roof prior to this had gravel and no roofers who quoted me on re-roofing three years ago mentioned anything about additional work to fix ponding.
Thank you.
