thanks for the posting opp.: our church has an appx. 9 year old steel roof (coated or painted yellow), with the lap and through fastened connection. Apparently (as we don't know yet the brand of roof mat'l and I personally haven't been up on it yet)the fasteners were overtorqued and where the fastener and sealing washer are, the roof has rusted around and through, causing leaks. As I'm told, there is some minor "bloom" in the open flat area of some of the sheets also, possibly due to poor handling, etc. We are looking at an economical repair solution. Assuming it may be possible to remove the old fasteners, then install new SS fasteners with larger od sealing washers to fix the holes, then power wash and paint the "bloom" areas. I did see an article in the "RSI" magazine showing how butyl tape (I think it was) was used to seal and repair a vertical seam roof. Any help, suggestions, etc. would be greatly appreciated. I'm sorry I don't have more information yet. Unfortunately, I believe we had poor installation and the general contractor and roof installer are no longer in business. We are in process of re-reading our contract with architect and trying to find drawings to confirm material of roof and screws, etc. Feel free to contact me via phone or email.

You may be learning that green is not always green. There are various paint systems, applied at various thicknesses and on various substates. Unfortunately it appears you may have received one at the wrong end of the scale. It does appear as if you are on the right track. You may want to be treating the areas around the screws as you replace them though. In recoating care must be taken to prep the roof surface properly. There is a long established company that makes metal roof recoating paints. I believe they or the product is called Calbar. Try and internet search and let them know they were recommended by the MRA. As to the butyl tape, it is used as a lap sealant between flashings and sheets. Some products incorporate it into their side laps. It is excellant if you were overlaying a piece of metal to patch a hole, then stich screwing the pieces together. Basixcally it is caulking in a manageble tape for that is compatable with most bare and painted metal systems.

Thanks Allan. I'll do some more research. Is there any particular roofing repair company that you or the MRA would recommend in our area. I haven't surfed the site yet. Sincerely, Thomas Graham
