The leaky 700 sf flat section of the ol' drafty castle adds to the charm, but not domestic tranquility.

We've re-roofed it with rolled rock roofing at least twice in the 39 years we've been here. We used the Dibiten underlayment last time. I remember looking at pour-on decking, but probably avoided it due to cost.

Has the technology advanced?

I'm a little out of date with this stuff too, Ralph. However, my experience in school buildings over the years is that I stayed away from the pour-on products. While they provide a pretty good water membrane, when they do fail (and eventually ALL roofing products fail) the water can (and usually does) travel under the stuff and drips out somewhere usually far away from where the leak is located. This is because they are usually applied over the old roofing allowing water to travel between the two layers. Repairs are very difficult because it's so hard to locate the actual leak.

Having said that, on a smaller area such as you have, with proper deck preparation and proper installation you might have better luck than you've been having.

Anyhow, my $.02 worth.

Only in China! Sorry Ralph. I couldn't resist!

Recently we did a remodel for a guy near the airport in Paso Robles.

I talked to the roofer (an old friend) about more high tech solutions, but he felt that hot mop built up roofing was still the best way to go for the money. Should last for 30 years in our inferno heat!

Ralph -- Have you looked into using EPDM rubber?

Mike that's what I was going to say. We put EPDM on a 50 ft houseboat up at the lake and it has been fantastic compared to the fiberglass. They put it on two ways 1- with glue and heat 2- they lay it down and adhere it to the side with a flat garnish strip of SS and screw it in with a little tension on the top to keep it smooth. We went with #2. We used white for the reflective properties but in comes in black also. We did 600 square feet but it is expensive about 2000.00 dollars material and installation. We got a five year warranty. The problem is you need a smooth surface to a point.
