What should the roof caulking look like?

Can someone tell me if there is supposed to be cracks down the length of the caulking or should it be completely cover the seam?
I circled the areas I am not sure about.

I had our roof cleaned and resealed and there are no cracks in the new sealant. The old sealant looked like yours does. I would have it resealed IMO.

Was that considered warranty work?

that was not warrenty, we bought the TT used and had the roof cleaned/conditioned and resealed. I think I paid about 250-300 for the work, they chargeed by the foot. 30ft TT x 9.00/foot ??. It was a mobile service and they came to my house and did the work in the driveway. We had a mystery leak we could not find, this took care of the leak.

Buy about 3 or 4 tubes of Dycor Lap Sealant and a caulk gun and do it yourself like I did

warranty may or may not cover it

the gap is normal cause mine was that way as well until I filled it in with the self leveveling lap sealant

check where your antenna enters the camper - I had a leak starting there cause the sealant was pulling away from the roof

X2 on the Dicor self leveling lap sealant. I have heard others on the forum have contacted FR about the roof seams and FR has sent them a couple of tubes for free.

And our mystery leak was indeed the antenna mount accoring to the guys who sealed our roof that is a common spot for leaks to develop.

How I noticed my leak was I had DVD's in the cabinet where the cable for the antenna comes thru - the paper cover was wet but the cabinet was dry which didnt make sense - I was looking on the roof and found the cable seperating from the sealant and knew that was my water leak - luckily I caught in time that it didnt create a mess.

I ordered a brand new camper and I only had it a month so you could get a leak at any time if you do not check periodicly or do any preventive maintenance - I asked my father and he was the one who suggested the Dycor Lap Sealant (Self Leveling)

So FR is OK with us doing this ourselves and I don't have to take it in to a trailer place and have them do it?

In the case of warranty issues in the future (leaks, delamination), is it better to have this maintenance work documented?

Yes you can do it yourself - one suggestion is to keep receipts of what you buy so you can prove when it was done.

By sealing the roof you are trying to prevent any leaks or delamination issues
I doubt they will question if it looks like it was done - if it wasnt done at all and there is mold and can prove it wasnt taken care of then they may.

As I understand it.......
Roof warranties cover the rubber membrane only. Inspection and repair of the caulk is the responsibility of the owner. Failure to do so could void any warranty claims such as water damage or delam. It's your choice whether you hire someone or do it yourself.

Also it's best to clean the old caulk with something like acetone or mineral spirits before adding new caulk. Caulk such as the dicor self leveling caulk should be the only type of caulk you use on your roof.

Labzy, all visible cracks should be re-caulked whether you see any signs of a leak or not.

Dicor Self Leveling Lap Sealant.

I agree that any visible cracks should be re-caulked with the Lap Sealant to prevent any leaks

I have seen the recommendation to use acetone to clean, but Alpha Systems, the maker of my TPO roof, specifically states to NOT use acetone on the membrane:
http://www.alphasystemsinc.com/files...structions.doc

I suppose one could argue to use it on the caulk and keep it off of the membrane, but I don't think I could split hairs that well.

Any comments on this?

I would not use acetone it will make the membrane soft. Our insurance requires us to have the roof maintained yearly, clean/condition and inspected for leaks.

acetone is a pretty strong solvent for a rubber membrane IMO.

I also was going by the recommendations I have read about using acetone. I haven't ever heard or read of any adverse effects of acetone on the roof membrane, but whatever you use you should be careful since these are strong solvents.

I guess I should have posted what I actually use. It's 3M Adhesive Cleaner that I purchased from my dealer. The way it smells it might as well be acetone. I've used it on two different tt's and my pop up. I was told to use it only where I would be caulking and I'm not so good that I keep it off the membrane completely, but I've never noticed any problems.

If we are careful and do no get any onto the membrane itself I think we will be safe, which makes me think that I will clean the caulking myself before I take it to get recaulked (if needed), so I can make sure of this.

Think I can use my nailpolish remover ???? It is mainly acetone............

Why take it to someone - if you decide to clean it and drive it somewhere most likely you will have bugs stuck to it

just caulk it - you will save a lot by doing it yourself
