Aluminum Patio Roof Replacement

My old roof was a pan type with 12" panels. It was replaced July 06 after the hurricane, with an insulated one, foam sealed between thin aluminum.

It has been leaking since installed. Any kind of moisture and it leaks.

At first it was only one spot, a constant drip at the seam joint, where it is attached to the fascia board..

The installer has been back about five times, with each fix it gets worse, now it leaks at three joints.

He was suppose to come back after the holidays and take off the flashing, check everything and replace it. He never came back and his phone is no longer in service.

I think if I caulk underneath, on the inside, it may stop the drips but, I'm leary that the moisture may get into the insulation or the fascia and create another problem.

Any insight on this problem will be greatly appreciated.
Thanks

Id try a roof coat on it on top . Dont seal it on the bottom. might call a different company that puts that kind of roof on. Have a sisterinlaw down there. Has that kind of roof on a porch Works real good No leaks. Sounds like the flashing is not right

There is a great roof sealant that I use on these types of roofs. It is called "Watershield" and is made by Geocel. Here's a link to a similar product: http://www.doityourself.com/invt/6696132

This and similar Geocel products work great for flat aluminum roofs, RV's, gutters, etc. Caulk wide gaps with Geocel's compatable caulking products, then brush additional seams with the brushable sealant.

If you Google for it, I'm sure you'll find GeocelUSA and their product page containing info on their "Pro Flex" and "Water Shield" products.

We usually run a long flashing out over the first 12" of roof and seal it to ensure nothing gets past it. Perhaps the leak is coming in where they attempted to flash the roof. Leaks are hard to find and stop, so be patient as they attempt to locate and repair your problem, but don't give up until it's fixed.

Sometimes you can hose down the roof, starting at the lowest point, and slowly work your way higher, and find the source of leaks. (If running water on the insulated panels doesn't cause it to leak, but running water on your shingles does... there you have it!)
