Roof repair products

Here is great thread from our Admin about sealing roof seams. It was written assuming the original seams have not been gooped.

What is on the roof currently? You probably don't want to hear this, but this group is not fond of roof sealer products, or goop, as it is referred to here.

The other thing (bad news) that you need to be aware of is - if the seams leak or have leaked in the past, you probably have rot that you cannot see. The water runs down, of course, and the skirt boards (the boards along the bottom of the frame) rot. You can use Mobil's ice pick method and get under it and poke around to see if you have rot or soft spots but the only sure way to know is to remove the skins. If it is leaking from the roof seams, you could have rafters or other framing boards with water damage or rot. This could be leaks that have not necessarily left a watermark inside but has run down the back or front and ends up in the corners. Check the front and back corners and the wheel wells.

If you are looking for a quick fix for a leak, I'm sorry to say, you're probably not going to find it here. But there is a lot of great info on how to repair and restore your trailer properly here.

Well I suppose I could move to Houston. Are ya single? LOL... I don't know how many people we have in your neck of the woods but I think there are a few. However what SusieQ told you is the truth. There is no easy cheap fix for a leaky roof. No matter how much goop you put on it the thing will  continue to leak because the aluminum expands and contracts with heat and cold. That severs the bond between the goop and the aluminum almost immediately. The goop remains but allows water under it in places. Especially on the roof. The roof also vibrates as you move because of the wind traveling over it. If the leak is because of a vent then all  you need to  do is remove the vent and re-seal it with new putty tape. If it is in the corners it is probably  due to the need for new putty tape under the J Rails. That trailer probably needs a complete re-seal anyhow.  They all do  at that age. It's pretty simple and not expensive at all. New screws and a few rolls of putty tape is all you need for this. The tools are a screw gun and a couple of screw drivers. 

Seams do not normally leak. If they do, then you need a  new roof. If the leaks are due to  holes from hail damage or tree limbs, then you need a new roof. That's not that hard to do either really. I've had many viewers both male and female who have installed a new roof by following my videos... You may wish to take a look at those. They are on my website.
