Installation Guidelines

Hi everybody, I'm a property inspector in Lexington, KY, and don't see a lot of metal roofs. A former client is having trouble with a new roof installed on an equine-veteranarian evaluation-track/office-space building that is virtually new, but besieged by leaks. The valleys are major problems, and the contractor has glued strips of rubber membrane over the flashing/roof seams. Do you have any ideas about what sort of installation detail(s) was botched? Clearly if the roof is installed correctly, the patches aren't necessary. Also, I'm concerned with the slopes--which are between 2/12 and 3/12--of the roofs on one side of the building. Are there slopes beneath which metal panels should not be used? Furthermore, I'm familiar with the problems associated with exposed fasteners. Are the fasteners on this building any better than the inexpensive, grommetted fasteners I typically see on houses? I realize I'm asking a lot of questions, but any help would be tremendously appreciated. I found your site via Mike O'Handley, who runs The Inspectors Journal, a forum for property inspectors. EDIT: I just realized I can only add one photo to this post. I'm going to upload more photos under separate topics. If this is a pain in the rear, I apologize. Thank you, John

The valleys are not handled well. I would aloso be concerned about the ridge. The fasteners should not be an issue on this new of a roof. I would suspect this panel is designed to be used down to 2:12. Have you been able to contact the manufacturer? Do you think condensation may be an issue as well? Todd Miller
