Dicor or Eternabond or?

[Deano56]

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?

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.

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.

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.

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.

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.
