Hello, We are currently having MetroShake stone coated metal shingles installed on our new home. The quote and contract stated the contractor would be using Tri-Flex 30 as the roofing underlayment material. The contractor has advised us that he did not receive his shipment of Tri Flex 30 therefore he is using a product called Typar, which he states is of the same quality. Today, he has showed up at the site with Tyvek as he has run out of Typar. I have the following questions: 1. In regards to quality of product being used as a roof underlayment what is the difference between, Tri-Flex 30, Typar and Tyvek? 2. Can you rate them in order of the better product being first? 3. Can you even use Tyvek as a roof underlayment? 4. From a pricing standpoint, which is more expensive?

They are all from the same family of research originally from the Dupont company.Typar and Tyvek is a breathable membrane designed to be used under the siding of a house. Tri-flex 30 is designed specifically as a severe duty roofing underlayment and is made in Brantford, ON and is one of the best roofing underlayments and typically costs more than the siding wraps which again to the best of my knowledge are not designed to be used as roofing underlayment.

I have never heard of Flextex and cannot find any information on it. Tri-Flex 30 is one of the "newer" synthetic underlayments. Properly instealled, they seem to work well.	Todd Miller Isaiah Industries, Inc. 8/24/2005	Share Or copy this URL: https://www.metalroofing.com/spirit/comment/3685/find/

Todd...I think the material you were referring is Feltex. Pretty nice product. Doesn't require a cap nail either.	Eric Novotny An informed customer is the Best Customer! 9/9/2010	Share Or copy this URL: https://www.metalroofing.com/spirit/comment/3687/find/
