I had a leak in the front end so i went over the whole top seal. the rear looked in need of help. There was some inside damage a few years back that was fixed, but the rooof was still bad. Here is the roof as i started it. You can see where it had lifted and allowed water under the seal.

I did alot of checking and i found out the flat steel roof flexes the most. I found this sealer just for this type of flexing @ Home Depot for $12 a roll and it was 2Xs as wide as any i found at the RV centers. To get a good bond i used denatured Alcohol and a few rags and a floor roller.

I washed the RV (it needed it) and then scrubed the area to be sealed with the alcohol and rags till they were clean.

I then cut out the correct size of roof tape. this has a silver side (TOP) and a paper side (this needs to be removed)

I started the 1st new seal at the edge of the old seal. there was not enough on the metal to stay sealed so this will improve the seal area.

i removed a small amount of paper and used the floor roller to roll it into the metal and all the edges of the old seal. I worked on this step longer than i needed too bu i wanted it to not leak.

to make sure there was a good seal i cleaned the whole area again.

the next row sealed 1/2 on the 1st line of roof seal i put down and completly covered the old seal onto new fiberglass of the end cap. i then over rolled this as well total time was 45 min. we now had 6 rains and it looks great and feel stuck the whole way. it turned out real good.

Here is another view of the completed job.

I made sure all air bubbles were worked out. this side is done.

Here is the front as i started it there was a hole in the center of the "V" and it was leaking down into the cab and onto the dash. i followed the same steps here alcohol wash till clean and measure,cut apply and work out all air bubbles.

I first ran a strip over the center and made sure it was rolled in real good.

you can see i overlapped the old seal and rolled it in good and tight

here is the last view. it now has been several heavey rains and no leaks. i am so happy. job well done.
