Well, this is an open question. Before you buck a aluminum or fiberglass roof I'm assuming you have no idea the process that it takes to remove the old roof and install the new.
To answer your question, you have to pre-drill holes in the new roof. You can make a hole finder to line up the old holes in the rail or just sight drill the holes.
Make sure you use the old holes in the rails. If you just start drilling holes in the top rail, then you'll have doubled the holes you need and it will cause the rail to lose it's strength and in time will become weak and break.
After you drilled your holes 3/16 drill bit or a #10 drill bit. Insert the 3/16 alum rivets and take your air hammer with the right bucking head (3/16 head) and a hammer. Consult supply company to get the right bucking head before going forward. Put the hammer under the rivet and push down the rivet with you air hammer and pull trigger. I use what i call a bucking bar. I take a solid steel bar about 1/2 thick by 3"wide x 6" long and use that to put under the rivet. Once the bottom of the rivet mushrooms out enough, the process is complete. I use soft rivet because it makes the bucking process very easy. Plus, if you use hard rivets it will make the removal of the roof and rivets harder the next time you have to repair the roof.
Hope that helps.
To install a semi-tubular rivet, you will need a rivet gun, a backing plate, and the rivet itself. Place the rivet through the pre-drilled holes in your workpieces, align the backing plate on the opposite side, and then use the rivet gun to compress the rivet until it creates a secure connection. Make sure to follow the manufacturer's guidelines for the specific rivet and tool you are using.
Most trailers are semi trailers. You're probably asking the difference between a semi trailer and a full trailer. A semi trailer is not wholly self supporting, and weight is distributed both the trailer axles, and to the tow vehicle. A full trailer supports its own weight fully.
You call it a semi because it pulls a semi trailer.A semi is a type of trailer. A semi-trailer, as opposed to a full trailer, means it only has axles at the rear of the trailer and a full trailer has axles at the front and rear of the trailer. We call these in the UK "drags", as in wagon and drag, where the wagon that pulls the drag can carry a load on its own, whereas the semi-trailer truck, or tractor unit cannot carry anything without a trailer.
Trailer is way more bigger than a semi-trailer. Common misconception between a trailer and a semi-trailer. Technically, a trailer has wheels in front and rear and is hitched to a pulling vehicle (car,truck,etc.) A semi- trailer only has wheels in the rear and is hitched to a pulling vehicle (car,truck,etc.)

A semi trailer is any trailer which doesn't fully support its own weight. That's the ver batim definition. A boat trailer for private use is not regulated the way a commercial use trailer is.
