One common question we receive from our customers is about re-doing an RV roof. It's not surprising, as the roof of an RV is essential to its overall structure and protection against the elements. That's why we decided to share with you a chat transcript between one of our knowledgeable customer service agents and a customer. Our agent gave some valuable insights into how to successfully complete this project.

[18:54][18:54] Dallin: Hey William

[18:56][18:56] Dallin: RV roofs are usually not structural, but need to waterproof.

[18:57] Dallin: Are you taking the old fiberglass off?

[18:58] william: yes and putting thin plywood

[18:59] Dallin: Ok, I would use a layer of 1.5 oz chopped strand mat, with 6 in fiberglass tape along the seams.

[19:00] Dallin: I would use ISO resin with gel coat over top.

[19:01] william: will that hold weight of air conditioner or person walking on it

[19:02][19:02] Dallin: How big is the roof?

[19:04] william: The replaced section is approx. 7x12 feet entire roof is 7x30

[19:05] Dallin: Ok, so you are not replacing the whole roof.

[19:06][19:06] Dallin: I would probably use the same layup.

[19:07] Dallin: So, 10 yards of 6 oz x 40" and 20 yards of chopped strand mat.

[19:08][19:08][19:08] Dallin: No problem.

[19:23] Dallin: 1.5 oz Chopped Strand Mat. not cloth

[19:37][19:37] Dallin: 70 to a roll of 1.5 oz chopped strand mat

[19:38][19:38] Dallin: No problem

[20:01][20:01] Dallin: 10 OZ of MEKP to 5 gallons resin.

[20:04] Dallin: Mix ratio depends on how fast you want it to cure. It is 2 oz per gallon, but you don't want to do a whole gallon at once.

[20:07] Dallin: You don't want to go lower than 1% MEKP.

[20:08][20:08] Dallin: To thoroughly mix it? 2 minutes is what the manufacturer says.

[20:09] Dallin: I would probably start at a pint, then work your way up. Get used to how the resin works.

[20:37] william: thanks Dallin I'm checking out

[20:38] Dallin: Great
