Question
I have a flat rubber roof about 500 s.f.
I had a company put on a Silver Coating.
What concerns me is the company sent 2 men.
They carried up some old looking buckets & mops.
They were done in lees than 1 hour.
Could they have done a proper coating in this amount of time & have had enough material to cover the roof in those open buckets.
I need to know before i pay the bill.

Answer
Hi desgner

Call the contractor and ask him what he used to coat the roof.
get the name of the product. look up on the Internet on this product.  look up the installation of the product your looking for cleaning before applying and how many Gallons per sq should be used.
ask the contractor if they followed the instructions before coating, then ask him if this was done why it only took an hour to do all this work.

The other thing is if you can go onto the roof and check the coating make sure it all got coated.

This job if I was to do it with an other man, more than likely would have taken at least 3-4 hours, We would have sweep off the roof and cleaned off any debris, then we would have blown off any loose dirt and then apply the coating.

please keep in mind All contractors have there own process  

Good luck
