bubble on EPDM roof by the seam

I have a bubble forming on the roof along the seam. it is about .75" wide and goes along the seam until it dissipates about 12" from the beginning. I am looking to repair by cutting and re attaching by glue and tape. I am concerned that the seam has some tension that will cause it to want to pull away further from the roof. Does anyone have any guidance on how they would repair?

thanks
