I've had to section in a piece of the roof and have realized I'm going to need to pull up a location on the roof that is down a little here is the pic..
What I need to do is pull up the line so this area does not sag down. Any sharing of experience with this type of pull and what tools you used would be appreciated.

Thanks

Hi MP,

If you weld, the area shrinks and pulls inwards. You need to stretch the weld and the areas next to the weld that turn blue so that you regain your lost surface area. You can bump the low spots up first with a dolly from below, but pulling is not the best technique for this fix. PM me for articles on welding and dent repair if you are interested.

It looks like what you've got there is an alignment problem that really should have been corrected before you did any welding. Is the bottom of this area in alignment? If the bottom is good then there must be some distortion on one or both of the pieces. Good alignment is a must before you weld these parts together. If you have to move it around some you'll probably need to break most of the weld loose on the upper area of the seam then put a jack or portapower under it with a block of wood and lift it up. Bob

Well I decided to remove a few of the roof spot welds and slide in a sling under the rail and with a tow rope a tree and a come along I got here back in line. Here's a pic of the setup, now don't laugh to hard:

Hey, there's nothing wrong with that pull, a pull is a pull reguardless of what tool you're using to do it with. Take a hammer and give the areas where the bending is taking place a few taps to stress relieve while the tension is on. Make sure it stays there when the tension is off. Where there's a will there's a way...
