How do I fix cracks in the roof?

I just purchased a 1988 Pace Arrow. Low mileage but the sun and movement has opened the seams on the roof. I remember my Dad trying to seal his roof years ago. What type of sealant should I use to plug up these cracks?

Thanks

Depends on what your roof is made of. Metal, fiberglass, EPDM rubber?
If things are moving to open seams, that needs to be fixed first, cause it'll just happen again.

I believe it's made of fiberglass. The original joints in the sections are were the problems lie. The manual says to re-apply sealant but does not state what kind of material to use. Silicon based?

I would pull it all off to be safe and clean it good.
http://www.schneemorehead.com/pdf-sm/SM5514TDS.pdf This is what we used on a MH a while back. Scraped it all, applied this.
Sikaflex makes great sealants. Proflex is my next choice. But not silicone.

You can hardly go wrong by using Dicor and Eternabond. But repair any structure first. Use SEARCH function on forum and you can get a ton of information about repairing a roof. Welcome to the forum.

See attached photos of the damage on the roof.

Given the information you gave me does it look like a Dicor fix?

Thanks
Brian

Looks like Eternabond to me. But as I said, structure first. You will probably need to peel back the damage to see what needs to be fixed. Then after that is all repaired, clean and apply Eternabond. Check the search section here and there is tons of info on proper procedures. Good Luck.

Look up Eternabond on You Tube. You will see the amazing stuff it can do.

Looks like someone tried to silicone?
As you can see, whatever it is, it's peeling up so it needs to be all removed first.

I just put some Eternabond on my roof because the caulking around a patch was coming loose. Great stuff, easy to work with. Now, lets hope that it keeps the water out.

I started to scrape it and it's all coming off so I going to use Eternabond . A roll of it is $160 up here though. I will try to find another supplier.

What could I find underneath that would require fixing?

Lots of rot in the wood structure causing the screws to come loose causing the trim on the seams to pop up.
