We have a screened in porch off the back of house which has an aluminum roof. The roof is probably about 18'x14'. There are three seams running along the roof where the pieces are joined together. This structure was already in place when we purchased the house in 2004. Two of the three seams had some water leaking through them. I got up there with a few tubes of silicone caulk and spread it around over the seams and a few other areas. I have stopped the one seam from leaking, but the other has not. I am thinking of trying something like this; https://www.lowes.com/pd/BLACK...Roof-Sealant/3013306 Would you recommend a different product? One note, this aluminum roof is white, so whatever product I use, it needs to be white, I cannot use black. | ||

I like Henry's products for roof repair, I have never used any of their white products but they make this: https://henry.com/retail/repai...-repair-roof-sealant | |||

I have used Henry's roof repair. Works well, but my advice is to use more than you think you need. Get the gallon can and use a large portion on a 3' x 3' patch even for a small leak. I used Black. Not sure about white. . | |||

If you want to do it right, you can look for a product called Mulehide Silicone. I found it at ABC supply company. It works phenomenally well. We used it on some bad spots on a roof at work. It’s pretty amazing stuff. It is head and shoulders better than anything you’ll find at Home Depot or Lowes. If you don’t want to spend the $$$ on that, try flex seal. I fixed a skylight issue in Washington with a couple cans of flex seal. The “lol” thread | |||

I recommend, if at all possible, doing the top of the roof's seams. Helps prevent a leak from "migrating"which will thereby make it harder to find if a future leak occurs. I have a 20x16 foot awning in my back (installed myself) which I have found out the hard way should have been sealed upon installation - not waiting until after the first rains to decide. (on the plus side, San Diego doesn't (typically) get that much rain.) Life moves pretty fast. If you don't stop and look around once in a while, you could miss it.

Yes, that is what I have done with the caulk and will do with this. The roof will support my weight and I can be on top of it. | |||

Forget silicone. If it is a seam on an aluminum roof, forget silicone. You need 3M 5200, it is a serious caulk that sticks to aluminum and is a near permanent bond. https://www.westmarine.com/buy...--158485?recordNum=1 | |||
