We are planning to re-roof our church, located in deep South Texas - Edinburg, TX. I have suggested we consider a metal roof and look at upgraded insulation at the same time. We have a steeply pitched traditionally asphalt shingled roof. We live in a hurricane area and receive more than 330 days of sunshine a year. Summers average above 95 and can go over 100. Air conditioning is our largest expense. Do you have any recommendations and/or suggestions for us? Thank you

Well you are on the right track in choosing a metal roof. Most carry the highest Class 4 hail rating and qualify for insurance discounts. I am assuming that you are more interested in air conditioning as heat in upgrading the insulation. Most metal roof systems accomodate this and can be installed over one layer of asphalt shingles. I would need the make up of your roof assembly to best advise you on how to accomplish this as existing insulation amount and type along with air barriers are very important. The new building code requires venting under the roof covering to deal with heat trasfer and condensation. Again most metal roofs can accomodate this. As weel try and choose a material that is energy star rated to keep your roof cool in all that sunshine. Choose a style and contact one of our member manufacturers to get their advise on meeting your needs. Good luck.

http://www.fpl.com/news/2001/contents/01015.shtml A white metal roof can reflect a great deal of heat as well - and metal gives up heat much more quickly than asphalt. Lighter colors are certianly worth looking at.....especially if air conditioning is your big expense
