Yea Mack, those work too. Doesn't really matter what shape the patch is, so long as they are present.
I think the guys liked the football shape because it was pretty easy to cut with a hook blade, and you could cut quite a few from scrap material.
In your detail it looks like they actually "set" the granules into the sheet before apply the patch. "Setting" the granules is done by applying a little bit of heat to the mod bit, and then troweling over the granules so they get buried into the bitumen. This way the patch can be applied to a smooth surface instead of a micro-mountain terrain. This is another indicator of a trained roofer.

Just curious, but what would you expect to see in a location like that on a cold process installation?
Footballs?
Goop & granules?

I don't think I've ever seen a cold application around here, and I look at hundreds of mod bit roofs every year.
Pretty much all torch down in Chicago.
You guys ever see cold patch (SBS)?
Once you have the big torch and know how to run it, I think torch is easier than cold patch.
I prefer APP over the SBS for a few reasons, the main one being you can "see" if the material is bonded by the squeeze.

The details for cold applied are slightly different. You should still see the patch at the apex of the cut on the base flashing, but the rest of the detail would not be viewable. If it was done properly, a course of smooth surfaced mod bit would have been installed beneath the granulated sheet at inside & outside corners.

Thanks.
I don't see a lot of cold process installations, but it seems to be becoming more popular. The rumor I heard was that insurance companies were giving the roofers a break if they got away from the torch.

That's true; there's more than a couple building fires started by someone torching down some APP.
My thoughts about cold applied are the same as my thoughts about water based adhesives.
They can be made to work, but the stinky stuff is sooooo much better.
