Re: Corrugated Plastic Roofing leakingCaulking is just a stop-gap measure that will fail (probably sooner rather than later). There is only one solution, and you aren't going to like it:
Remove the roof and fix it.
I inherited a similar (corrugated metal) roof on a 20x20 patio several houses ago. The idiots that installed it made it with no pitch. To add insult to injury, they only overlapped the sheet by a few grooves (trying to save $, I'm sure).
I ripped 2X lumber at angle for each ceiling joist. I ran new cross slats because most of the old ones were rotten. I laid the old material back down (with proper overlap!) and bought a few more sheets of material. It was enough to keep water from pooling on the roof deck. |

I know that this won't last a long time but if this fixed it for 2 seasons I would be happy. I looked at replacing the roof but the structure is 19' x 14' so just in material I am looking at around $300. I would rather do the $25 fix and budget the roof replacement out. |

You may as well send that $25 through a paper shredder.
There's an old expression: "Throwing good money after bad".
You'll be lucky if the caulk idea works at all, even temporarily. You'd be better off saving that $25 and putting it into a real fix. |

So in your opinion what is a cheap fix that allows me to continue to use the roof that is in place without spending over $300. The leaks aren't bad at all I had dripping in two areas last week and that was it. All the seams aren't leaking just a couple. I also have another flat roof just like this over my porch and that one doesn't leak at all. |

Sometimes, there isn't a cheap fix. That's life.
I'd be really surprised if it actually cost $300 to fix it. |

The following may be a "cheap fix" but only if you ignore the investment that you are making in terms of time and effort.
Instead of applying the silicone caulk to the seem edges you should detach the panels from each other, clean the overlapping surfaces thoroughly and then apply a thick bead of silicone (in the middle of the dry, clean overlapping area) just before putting the panels back in place.
It is hard to say how long it will last but it will fix your problem initially. Heat and sun will eventually deteriorate the caulk and cause it to lose its elasticity. Thermal expansion and contraction (or mositure and frost depending on where you are located) will then break the seals.
Since you say you are planning to replace the roof within a couple of years you should also be aware that sticking the panels together with caulk will make it a tougher job to remove them later on. |

Yea the stuff I recommended will be fine for a long time. I just hate working with it. Oil based is messy! |
