I have been doing several roof inspections since Hurricane Micheal hit in Oct 2018. I have noticed a common theme that I have received different responses about. On the first course of shingles on the eve sections, I have seen numerous roof coverings that have an additional starter strip shingles applied to the roof eve. I know that this is an acceptable way to bond the first course when installed properly. I also know that the cellophane strip on the underside will eventually “dissolve” when the roof heats up and completely bonds to the drip edge (This I have heard from several roofers, I don’t fully believe this). So my question, I know the FRC R905.2.8.5 for the drip edge states that if the drip edge is installed over the underlayment, then a minimum of 4" of roofing cement must be applied from the drip edge back under the roof covering. Does this still apply with the starter shingles? I have got mixed responses with this and I want to ensure I’m documenting it correctly as a defect or not in my clients reports. Many of the new roof coverings thus far have yet to bond due to the cooler conditions and most roof covering I am able to uplift the first course of the shingle layer…
I also apologize, this is not the best picture I had a the time of this posting, it’s more of a reference on what I am seeing. 
I would say yes!
However,
R905.2.8.5 Drip edge.
Provide drip edge at eaves and gables of shingle roofs. The overlap is to be a minimum of 3 inches (76 mm). Eave drip edges shall extend 1/2 inch (13 mm) below sheathing and extend back on the roof a minimum of 2 inches (51 mm). Drip edge at eaves shall be permitted to be installed either over or under the underlayment. If installed over the underlayment, there shall be a minimum 4 inch (51 mm) width of roof cement installed over the drip edge flange. Drip edge shall be mechanically fastened a maximum of 12 inches (305 mm) on center. Where the Vasd as determined in accordance with Section R301.2.1.3 is 110 mph (177 km/h) or greater or the mean roof height exceeds 33 feet (10 058 mm), drip edges shall be mechanically fastened a maximum of 4 inches (102 mm) on center.
Thanks for the info Ray. Some of these roofers make me think I’m taking crazy pills sometimes! I’m glad to see I’m heading in the right direction
The 4" of tar is not to seal the shingles above, it is to prevent water from getting under the drip-edge when installed “over” underlayment. The roofing tar is nasty stuff, so it’s a better practice to install the drip-edge “under” the underlayment at the eaves. The starter course is needed in both cases at the eaves and recommended at the rake edges to stiffen the overhanging part of the shingle. The cellophane strip does not get in the way of the adhesive strip when shingles are installed, it’s only meant to prevent shingles from sticking while reversed and bundled. It’s not necessary to remove the cellophane and it doesn’t dissolve (it does deteriorate over time) when sun heats the shingle, nor would it help sealing if removed.
Thanks for the additional info Simon!
I put it at all drip edges. We use it in the calking type tubes for easier application.
I would take it one step further with that mastic mess and add a fiberglass mesh to it. I believe it’s called 3 coursing. Too much? I bet no leak but plenty of mess.
