How to patch aluminum siding???

11 years ago

I'm replacing a decorative vent on the side of my house and noticed that they had cut out most of the siding behind it. Seems stupid to me since I assume some rain can get behind the siding. Before I put up the new vent, should I close up this siding holiday? I was thinking of nailing in place flashing strips so that water would run down outside the siding, not behind it. It will be invisible behind the vent.

I think we need to see a picture to understand what they did and whether or not it is a problem.

If you nail it, you'll probably end up with bent aluminum. Instead, consider fastening it with a couple rivets.

Imagine siding with sections missing and the missing sections are adjacent for about 7 siding boards, roughly the size of a 30' X 30' circle and you have my situation.
You make a good point about nailing into the siding. I'll predrill those since I don't have rivets. But I can certainly nail where the siding is missing.

aluminum siding moves the same as wood and or vinyl would. Predrilling will not be enough.

"Predrilling will not be enough."

Ever noticed the nailing holes' in aluminum and vinyl siding are actually slots?
