Does anyone know the purpose of the grooves on the roof of the truck, besides being a pain to dry.

 

They do two things. You'll notice the grooves nearest the doors are deepest. Since windows no longer have the rain guards around them, these grooves channel the water away from the windows. The second purpose is strength... a corrugated roof is much less likely to flex, thereby providing a stronger base for attaching the headliner and goodies like the entertainment system or sun roof.

 

They are simply put there to stiffen the roof panel, just like some of the formations in the cargo box.

They may do other things as far as diverting water or whatever but that is just incidental.

 

I wasn't disputing you in any way beast....we posted at the same time and yours just popped up first

 

I'm pretty hard to rile, Logical... besides, you could be right.

 

Ford put them on so those of us who have the moonroof can enjoy a nice refreshing splash of water from the roof when we drive off with the moonroof open.......They funnel as much water as possible into the cab.

Strongwind ROFL!!!

 

Speaking of the grooved roof, I was washing my new Screw for the first time this weekend, and I noticed that the outer two grooves did not have good paint coverage on the vertical sides of the groove. Anyone else have this problem? Should I take it back to the dealer to get the roof repainted? The color is deep wedgewood blue.

Thanks

 

I found a the same thing on mine. I'll I did was wash it and put a nice protective film of wax, and it looks good. If still not happy definetly take it to the dealer.

 

Mine's bad too. The paint in the outer groove of my roof is blistering.

The dumbest thing is the body shop at my local dealer is open from 8 to 5:30 M-F. Needless to say if I have to take time off for work to get this fixed I will not be happy.

 

I know that the grooves are for strength, but I would much prefer outies to innies in this situation. Drying is a royal pain!!

 

You guys are both right!!!!

This is one minor reason they fared better then the regular cabs

Beside the mid pillars...

 

I have Oxford White, and I have noticed the two outer grooves are starting to yellow, whereas the others look fine!!

 

If you will notice those grooves on the outside are filled with compound. That makes it look like the paint is not smooth. As for yellowing, I guess if the paint job is not good or does not cover well the compound would begin to bleed thru. My paint seems to be fine, it is just wierd to have that soft compound in there instead of metal.

 

Muahaha, I did the same thing! Opened the roof...drove down the hill where I live....boom, second shower!
