AboutTodd E. Miller Expertise I am available to answer any questions pertaining to residential (or other sloped) metal roofing. I have knowledge of most available products but I like to approach projects from a "needs" basis and analyze them individually. Additionally, I can answer most questions about building ventilation.
Experience I have worked for a manufacturer of residential metal roofing since 1980. I currently serve as President and have been involved with a wide variety of projects of all types across the world.
Organizations I am a board member for Metal Construction Association, Metal Roofing Alliance, the local United Way, our church, and our son's school.
Publications Over the years, I have had articles appear in several trade journals including RSI, Remodeling, and Qualified Remodeler.
Education/Credentials I have a B.A. in Communications and have also completed three years of training with the E-Myth Academy.
Question What are the pros and cons of putting the wooden slats between shingled roof and new metal roof?
Thanks
Sharon
Answer Sharon,
First of all, it is important to know that not all products are designed to be installed in this manner.
As far as why to do it if the product can be installed that way? The main reason would be if the attic cannot be ventilated. Having the airgap behind the metal would help some in avoiding condensation and also help some with energy efficiency and to guard against winter ice damming.
If the attic is properly vented though (per building code) then I see little reason for installing the roofing on battens.
