The fabricator for the Milwaukee City Hall project was Heather & Little in Markham, Ontario. I know it is not the west coast but perhaps they have worked with an installer the can recommend in your region.

We have a large inventory of historic standing seam sheet metal roofs here in Winchester, VA. I too have been on the roofing part of this research trail. The National Park Service has Preservation Brief #4, Roofing for Historic Buildings which has a small section on metal roofing. But a huge PDF can be downloaded from the Copper and Brass Research Association, Roofing & Flashing Manual, dated 1948. It was a part of every architect's library back in the day. It is mostly about copper but you can get good folding and maintenance information anyway. There are a few old companies that still do this work on monumental historic buildings. Wagner in Washington DC is one, Heather and Little is another.

Hope it helps,

Hi Gordon

We have faced this situation a number of times and have saved the historic fabric by using automotive bondo, along with typical fiberglass mesh and/or light gage sheet metal backing as needed for areas that have 'little to no' metal left.  This has been successful even where there was dramatic deterioration.  I don't know that this type of work falls into any traditional 'trade' category but many craftspeople are familiar with the use bondo for car body repair; it is readily available.

If complete replacement is needed, there are artisans who can work with metal replicating just about anything - but repair may be easier.

We also just used the 'bondo' approach on a badly damaged 50 year old aluminum facade with success, with a silver spray paint closely matching the visual character of the undamaged aluminum nearby.

Hi Gordon and all All: Some thoughts on early 20th century cornice problems (endemic in the Northeast and Chicago). Check out:

*Standard Practice in Sheet Metal Work (1929) from SMACNA.org, a manual of original period details (this sheet metal trade org. began with cornices before HVAC)

*GFRC (glass fiber reinforced gypsum) as a substitute/repair material; Towne House Restoration does this work in NYC

*Ditto fiberglass (Architectural Fiberglass Corp. in NYC specializes in this work)

*W.F.Norman in Nevada OK (still offers some galvanized steel cornice parts)

Hope this helps -Gordon
