Topic tags/keywords: question deck garage roofing

We have a deck over a garage (all after thoughts on a raised ranch). It appears there is some sort of roofing material under the deck boards, but they also appear to not be keeping water from leaking into the garage. I think there might have developed some sags where the water pools and eventually finds its way through the floor and drips from the ceiling joists below into the garage.

To fix this, my thinking is that I can pull the deck boards (which would use a flipping anyway to the likely still nice looking side) and apply some sort of sealant on top of the current rolled out material. I could swear I’ve seen something that can be brushed on like a driveway sealant, but I’m having a hard time knowing really what I’m looking for.

The pooling will continue, I’m sure, until re have enough money to destroy and rebuild the whole thing, but if there is a durable water resistant coating, I figure it’s much better than the significant amount of water dripping (probably 30 gallons or more just from the winter thaw).

Thoughts or advice?
thanks,
Chris

I have installed decks on flat roof garages. The decks were built in 4 sections, that way any one section could be pulled up for a repair beneath. What is the composite material on the roof now, this makes a lot of difference as to what you can apply. Also, a couple of pictures of the deck and roof would be helpful.

Ok, in the mean time, look at this product. Flat roofs are notorious for ponding water. Even on well designed roofs, eventually you will encounter some minimal ponding. I have used this product over both old rolled out roof material and badly laid and sealed rubber membrane roofs with good success. Take a look, read it carefully to make sure this is the product your looking for.

I checked the product link and it looks like the right stuff. We didn’t build the deck.. previous owner did, and like many of their “fix ups” it wasn’t done with the thought of longevity at all. We intend on rebuilding the garage and just putting a new kitchen/living space over it…
Anyway, thanks for the advice. I’ve not pulled up any boards yet to get a better look, so can only see between them right now. Perhaps a pic or two this weekend if I get the chance.
