Roof Leak

I have a roof leak in the rear left side by the cold air return. I have taken the hose up on the roof and sprayed around the rear ac unit and the gutter with no luck finding the leak. The roof has been re-caulk last summer. Any ideas would be helpful.

he leak could be anywhere on the roof because once the water is inside it will drip around. Make sure you look at the cap on the antenna wire. Also look around all the vents, clearance lights and skylight

I found mine in the cap seal. As I looked with a magnifying glass I found voids in the caulking. The screws were placed about and the ends of the steal strips were never screwed down. The only way to really find this is by feeling and pressing on the caulking once a void is found you need to scrape the old caulk out drill new screw holes through the metal strap and threw the fiberglass but not the wood below place new screws re-seal and wait until Summer and fix properly. Other alternative is 8" EternaBond tape. Look at the antenna rubber cap. Use only Dicor

Mine was around the TV antenna wit. Make sure the cap around the cable has not moved up.

When we had our Roof Membrane Billow up in Texas and require roof replacement, the roof membrane showed no damage or failure, it appeared the air got under the front cap sealant where the membrane joins the front cap.

That's what happened to ours. If we require a whole roof replacement I am sure my husband will sell this rig. We have only owned it a little over a year. ��

How bad is it billowing up? A small area or a large area that would probably require adhesive to get it back down? If it is a small bubble and you've found it caused by air getting in at the front cap,I would have no problem using EternaBond tape to solve it. Once that stuff is on, it is very difficult to remove. I had a leak around a living room vent in SOB and could never really figure out where the water was getting in so I sealed the entire vent with eternabond and never had a problem after that. When a small leak developed in the bedroom closet I did the same thing across the entire front where the cap and roof material meet and the leak never came back. I believe in that stuff so much that I've been thinking about doing it to the front and rear caps of the Redwood just for preventative measures. After all, that's how most manufacturers seal the slide out roofs. You have to use a heat gun to remove that stuff so I would want to make sure the loose material is adhered before I put the eternabond down. You can go to the Alpha products website or call them and they can tell you what adhesive to use on the Alpha Ply roof.
