Foam roof installation question

I'm having a foam roof put on my Rummer in Portland Oregon and I have a question concerning the installation process. Does the roofing company put on new flashing before spraying or do they spray to the facia board and then flash last? I ask because the company sprayed on the roof and did not put any flashing on at all. Now I'm trying for figure out what to do? In some areas the foam is higher than the facia by 2 inches. I appreciate your suggestions and advice.

Thanks,

With a facia board like you have, the flashing needs to be under the foam to protect the joint between the foam and the wood. Is this new construction ? What happened to the flashing that was there? Does Portland have a Building Department ? You notice that I'm not asking about the Contractor. I kinda doubt that you hired a real one.

Thanks Randy for the reply.

My Rummer (http://portlandmodern.com/rummer/rum_featarticle_index.html) was built in 1979, so it's not new construction.

I'm sure Portland has a building department. Should I contact them for some reason?

The spray-foam company removed the old flashing. They told me it would be best to remove the old flashing, spray the foam and flash over the top of it. I didn't know any better and figured they knew what they were doing. Of course, now I've put in hours of research and found that other companies put down flashing first.

It's too bad you guys don't have an office up here. There's plenty of Rummer owners like me that want a quality roof.

David,
There are situations where it's best to install flashing after the foam; Walls with metal caps; Walls with siding where the flashing goes under the siding and over the termination of the foam. Email me a photo of the edge at info at durafoam.com. Maybe there is a good explanation for your situation.

David,
The old flashing secured the edges of the tar roof to the wood facia. In your photos you can see the old tar paper edges flapping in places and not even sealed. I seriously doubt that your 'contractor' has done many roofs. This whole contractor thing is based on the premise that they do something a customer is willing to pay for.

Keep after them until you are satisfied with the job. I doubt any responsible authority would say that the job is done correctly.

Thanks for taking a look, Randy.

What would you recommend to seal the edges? Raised-edge, foam-stop flashing? The "contractor" suggested adding heigth to the facia board and he'd come back out and seal to the board then install flashing on top.
At this point I can't rely on what they tell me is best. All my research shows that the proper install has flashing down first and SPF over the top.

Thanks again,

David,
Please get your local building department involved.

This link shows a typical edge for your type of roof. You might have them get building department approval before doing anything...or show you an acceptable example on another job they have completed near you.
