I'm at a point I can no longer put off re-doing my roof on the MH. It is galvanized metal with 2 interlocking seams running down the length of the roof ending at the front and rear seals as I'm sure most MH are the same.'ve been looking at Eternabond ans Dicor 4" wide sealant tape, eternabond is 35 mills and Dicor is 25, also Menards has a 4" tape for 7.00 per 10' roll which equals 35.00 for 50'. Anyone have some pros and cons about any of the above?

I have only used Eternabond so I can not speak for the Dicor tape. What is the brand the Menards carries? That is a good price. 4" x 50' roll of Eternabond goes for around $80. I will be doing the roof on my new fiver soon and I will be using Eternabond. It is easy to work with and once it is down, it does not come off.

Seams in metal roofs are only part of the problem. The installation usually used either staples or nails. Every point of penetration starts to enlarge.I would suggest cleaning the roof good, sand down the oxidation and treat the whole roof with a good quality roof coating such as Liquid Roof, Dyco 890 or Dicor Metal Roof Coating.

Do it once and do it right - I have the same metal roof with seams and I ran 4" eternabond across all the seams and then finished off the roof with the best quality elastomeric I could find.Total cost was around $220 - I might have been able to save $50 on cheaper materials but then had to redo it next year.My roof is screwed down by the way.

I also used Eternabond on a previous MH with an aluminum seam across the roof. I put in new screws to cinch it down tight then taped the whole thing, never had a problem after. There was previous silicone on the seam but the tape sealed beyond that on both sides, worked perfectly.

Eternabond is the only way to make a good lasting fix. It is worth the price!! It will stick to almost anything except silicone. If there is some silicone there it can be bridged as long as there is at least 1/2" for it to grip past the silicone. Be careful when putting it down because it does stick. I did it on all of the seams on my '96 Pace Arrow to prevent any leaks and never had a problem.

Dicor or Eternabond or? | Good Sam Community

I don't understand exactly what you are saying in your quote. Could you post a picture?

Are you talking about the side seams like in the picture below? Under these seams is a tape caulk that is soft and pliable. I changed one of mine needlessly before I realized how effective the tape caulk is at sealing.

Today I removed all the old caulk from the front seam of my rubber roof. I cleaned the rubber roof with Scrubbing Bubbles and the fiberglass with acetone then applied Eterna Bond tape to the seam.

I had eternabond on my 4 roof seams and had camping world fix a hail damaged seam on my MH, They replaced my eternabond w/ some 4" alum tape that lifted & failed after 2 years causing several leaks and I fixed it w/ eternabond to stop the leak. I wouldn't use anything but eternabond.

I cleaned the area with Scrubbing Bubbles, then acetone before covering it with Eternabond roof tape.

TCP seems to do a good job - give it a good scrub with it, rinse it off and let the whole thing bake in the sun for a day before applying

If you have a lack of sun, come take a trip to AZ, we have enough for everyone at the moment!!

I have used Eternabond extensively. It works great.
