Fixing deck/roof pond

CallMeVilla · Sep 8, 2015

Curious how anyone approaches fixing a deck or flat roof sag which has caused a collecting point for rain? This is a repair where the owner does not want to rip off the existing.

I have a process I have used which is four steps. Apply sealer, float self-leveling cement, re-seal, coat with polyurethane top coat.

What do you do?

I was at ABC Roofing Supply a while ago and they had a product that was a self leveling sealant that could be used for that exact application and for the life of me I can't recall the name of it, I'll call my salesman there in the morning and find out.

Depending on how deep the sag is, you could be adding significant weight to the roof.

Small sag (< 3/8") covering a 4'x4' area. The self-leveling cement is light. The sealer and polyurethane is nothing ....
