Recommended Paper under 5v groove&: "1. What should be installed on top of the particle ..." - Jenny Dow (4/8/2019) | Installation

What should be installed on top of the particle board installed just after framing a new construction home? (South, central Mississippi in hot & humid climate) See image of my house on my profile. The paper installed is grey & feels like it would block water. (Difficult to tear; need a knife to cut) Is there a max time this paper can be on prior to the metal roof going on? My Hardie Board siding install has taken over 3 months so this paper has been exposed for a long time! (Only 2 people installing siding) We picked a 5 v groove, panel roof. What gauge do you recommend? (Central Mississippi) Is 26 gauge good? (What is stocked here, otherwise I special order) Note: To paint my house down the road, our lower roof will be walked on. It may be walked on to power wash off the bugs too.

It appears that your roof has a synthetic underlayment on it, which is not uncommon beneath metal roofs these days. It has to be installed properly but most synthetic products are warranted to last from 90 - 180 days exposed to the weather. As far as the roof you select, metal comes in a huge variety of products and grades, including exposed fastener and concealed fastener. There are different grades of coatings as well. And, of course, proper installation is critical. 26 gauge is certainly a fine gauge for the type of exposed fastener panel you're considering.

How do I know if my warranty is for 90 or 180 days? We actually just passed the 90 days. Can you tell from my photo if the synthetic paper was properly installed?

The photo is too small for me to see detail. The warranty would come from the manufacturer. Is there any name printed on the underlayment? If not, you will need to look for a roll label or wrapper or ask the contractor.

I think it simply says 84 Lumber on it.	Jenny Dow New construction: Metal v-groove, 26 gauge, roof 4/8/2019	Share Or copy this URL: https://www.metalroofing.com/spirit/comment/24178/find/
