I'm having the same delima, last summer painted metal was running 30% more than asphalt shingles in MO. That was when fuel was 4.00 per gal and everyone was blaming rising prices on oil, didnt check to see if asphalt ever came back down in price, that would be rare, hopefully I'm wrong, were gearing up for our roof late spring, still can't decide, metal or shingles, good luck to you.
In texas I'm paying less than $3. a linear ft for 26 guage pro-panel/rib type painted (36 inches wide). If the pitch on your house isn't super steep, metal would be the best way to go if you're doing it yourself. The labor is a breeze on a std roof line compared to laying shingles.
Greg et al, You might want to consider reading Stewart Brands book....How buildings learn..What happens after they are built? I like steel but prefer true standing seam.......no unsightly nails or screws. Stewart likes steel too!!!!!!!
Go with metal. Its made of recycled content and can be recycled at the end of its long life. Asphalt will need to be replaced and thrown in the dump one or two times during the life of good standing seam roof. Watch for sliding snow areas (if applicable), it can be tricky in that situation. Yes it costs more up front, but not in the lifecycle costs. If heating is a concern, galvanized will reflect heat, asphalt will store it. Painted standing seam can have heat reflective pigments added if you are in an appropriate area.
if you do the metal right, with ice dam protection and protected edges and fastenings, it should last literally forever. and you get to pick colors. it sheds water and snow and ice much better and will not have any problems with wind. depending on your home design, you can also do metal that replicates tiles or shakes.
Julie and I had planned to do a metal roof all along, until we talked with three good roofers in our area. We have a shed dormer and two gable dormers on our roof. Our roof is a 12/12 pitch down to the porches, then goes to a 12/6 pitch over the porches. We were told by all three roofers that we would be best to choose asphalt shingles for our roof. We did and we are very pleased with the outcome. Asphalt shingles come in 30, 40, and 50 year shingles. One thing to consider also is the sound of rain and hail on the roof; we won't hear either nearly as much as we would have with a metal roof. Feel free to look at our pictures and see what you think. You will get advice from owners and builders trying to convince you that metal or shingles is the way to go. When it comes down to making a decision, talk with roofers who know what will be best for your roofing system. The roofers I talked with have done both metal and asphalt shingle systems. Dave
