Aligning roof panels - need suggestions please.

I have the traditional style galv corrugated metal roofing and am wondering how to keep it all aligned when installing. The yard I purchased it from was of little help and all the company can tell me is to "temporary attach all panels, align, then permanently attach". My roof is steep,....10:12. Anyone have any tips? How does a person stand on such a steep metal clad roof without 1) sliding off & 2) without bending the metal? It's pretty thin,....29 gauge I think. I hope to begin installing in on Thursday. Any and all insight would be appreciated. Thanks.

Thanks for the question. First of all, I have to get on my soapbox -- PLEASE -- to anyone looking at buying metal roofing and installing it yourself -- if your supplier and the manufacturer cannot provide you with detailed and clear installation instructions, let that serve as an indication that you are not dealing with quality suppliers who care about what they are doing. If they don't care whether it gets installed properly then, sadly, they probably don't care whether it gets manufactured properly either. I strongly suggest looking for metal roofing which is in compliance with the MCA Certified Roofing Program. Now, you will need to make sure the panels are perpendicular to either the ridge or the eave. This could be easy or it could be difficult depending upon your home's age and construction. Generally, I feel that it is best to run perpendicular to the ridge though that will not be the case if your ridge line is not straight. There should be trim pieces on the gables and the eave. To maintain squareness, chalk vertical and horizontal lines on your underlayment and follow them. For roof access, it will probably be best to hang ladders from the ridge using chicken hooks and then use ladder jacks to run walkboards between the ladders. Use pieces of wood to brace the ladders up off of the roof so that you can work underneath of them. I hope this helps.

Hello I am trying to get a new vertical panel metal roof installed on my 1785 Cape Cod house. The eaves have been straightened out with new facia boards and so the panels can be run perpendicular to these. However, the peak has a "sag", as does the whole side of the roof. What do you recommend is the best way to deal with getting the sag out. If the peak is to be straightened, it will need to be supported (I assume) as I am in the snow belt and so the weight of snow would dent the unsuported peak if it was just shimmed up un a few places. By straightening the peak and the sag on the side of the roof, will this make it easier to apply the panels so that they are straight - and will the roof look straight when finished. Joanne

If you can get the peak and eave running parallel to each other, that would be good. Of course, one big issue is whether they are perpendicular to the gables and also what effect any bad sags in the roof will have. Special wide flashings could be made for the gables to minimize the visual effect of any unevenness if the gables are not perpendicular to the peak and eave. You may need to consult a structural engineer regarding shoring up the peak.
