Suggestions for remedying

I build a shed last year - flat roof.

At the back I decided to fit a drip edge into a gutter. The beam the gutter was attached to has warped over the summer, lifting the gutter in the middle and pushing against the drip edge. The drip edges were nailed to the boards with long felt nails which were then covered with the roofing felt.

The movement has resulted in one of these nails where the two pieces of drip edge meet, being pushed up - almost all the way out, so that there is now a bump in the felt above. I'm going to remove and refit the gutter, but can't think how to deal with this nail. I can't just push it back in without using a hammer, and to do so would damage the felt and the felt is glued to the drip edge so it's not going to lift easily until I'm ready to redo the whole roof.

All I can see I can do is to hammer it in (or cut through the felt and remove, and then patch the felt with a new piece on top and plenty of adhesive.

Thoughts?

rick1632, good evening.

One trick to consider is OK use a hammer but?? place a [say] 50.mm X 50.mm timber between hammer head and bulging felt, tap lightly.

Can at times work, no Guarantees??

I considered that, but it won't work - you use a piece of timber in this way for one of two reasons.
1) To spread the impact of the hammer over a larger area, softening the pressure on an individual spot
2) To dampen the blow - i.e. spread out the force over a longer time as the wood will compress - this is important if what you are hammering is brittle.

But in this case, the area being struck is far smaller than the hammer head anyway and thus there is no "spreading" out to do and felt isn't brittle, so the wood would serve no purpose.

Besides, simply hammering it back in would likely mean it pops out again if I'm unable to rectify the conditions that caused it to do so in the first place.

I think I have no option but to cut the felt, remove the nail and replace with a screw - with hindsight I should have used screws for the dripedges in the first place as there's no danger of the head going through the plastic. Then patch the roof when done. Unfortunate, but better than the felt tearing and water getting in.
