Do what we used to do with glass green house. White wash it, just take some lime and water and mix it till you can brush it on with a heavy brush and forget about it. Put it on at the start of summer and by winter it will pretty much have washed off so you get the sunlight when you want it most. Very cheap and it works well.

does the roof have any insulation under the metal portion ?
if not take an infer red thermometer the type with the laser and on a warm day shoot the under side of the ceiling. even on white roof buildings with good ventilation , a vented ridge and 2 larger doors the under side of the steel may be 50 degrees hotter than the air temp
2 buildings next to each other one with a thin layer of insulation neither having any light coming through and the ceiling temp in the insulated building was 144 and the ceiling temp in the building with some insulation was 86 that is a 58 degree difference the two buildings were 15 feet apart both had all doors open the un-insulated building has large exhaust fans to try and clear the heat out but they just can't move enough air fast enough.
so while light might be causing warm spots an un-insulated ceiling might well be heating it up a lot also.
if it is primarily the sun coming thru the clear ridge , some shade cloth hung from the bottom of the trusses might dissipate the intensity enough leaving the shade cloth to heat up with air moving through it and exhausting yet leave you enough light to see and and reduce the warm spots on the floor.
shade cloth is also use on green houses in the summer to reduce the intensity of the light coming in , typically it is done over the top but it would be worth a try to do it from the trusses first and see how much it helps before you have to go for a walk on the steel and try and find a way to fasten it from to the roof

Cieling fan run in reverse. Ridge vent.
swampgas chili and schmidt beer makes for a deadly combo

Cieling fan run in reverse. Ridge vent. I have two ceiling fans running in reverse and a ridge vent. It was 91* outside today and almost 100* in the building.

I think the cheapest, easiest way to block the clear ridge cap that is reversible would be to get five sixteen foot long 1 x (whatever width needed to cover one side of the ridge vent). Butt them together with screws and lay over the top of ridge vent. the fifth 1 X will be cut in half to form the cover for the last eight feet of ridge cap (16 + 16 + 8 =40).
Butted together they will form a 90 degree angle which I doubt would lay flat on your ridge (your roof would have to be a 12/12 pitch). but it will still work. If you have carpentry skills and want the cover to lay flat rip the proper angle on each edge before screwing together.
Attach with a minimum amount of 2.5"-3" metal roofing screws, like four or six per 16" cover, two or three per side. If it works and lowers the interior temp significantly you can do a more permanent solution like painting the clear cap or replacing it with a metal cap. If it doesn't make a big difference, simply remove. Be sure to put roofing screws into the holes left from attaching the cover.
1 x pine material is relatively inexpensive and can always be used for something in the shop.

It's a uninsulated metal building, and the clear "cap" is a ridge vent. It has the mesh filters running down both sides. Someone at work suggested plastic dip paint that can be peeled off if needed. Whitewash it! Blocks the sun in the summer and Mother Nature takes it off in the fall. Doesn't get cheaper or easier than that.

Someone at work suggested plastic dip paint that can be peeled off if needed. an un-insulated building and your only 8-9 degrees warmer in than out your doing great. exceptional you must have a good ridge vent and a lot of doors open and good air flow. white wash that clear cap or put up something high to block the sun from streaming in. but I will bet it doesn't help more than 2-3 degrees in overall building temp. insulation is what is lacking , shoot the underside of the steel on a sunny day with an infer red thermometer and you will see your real issue , when the ceiling is 30+ degrees hotter than the air temp outside it is like trying to cool down an oven with the broiler still running you can open the door but it will still be hot.

If it is a vent then I would not suggest closing that off. Hot air rises and a pole barn with a 3/12 or 4 /12 pitch (the more the better) will create a chimney effect, especially if you have side doors open etc. If you notice that there are bands of hotter places down where you are walking due to sun penetration you can be sure that it is much warmer near the ridge cap. If you keep the shed closed up most of the time you are not letting the natural air system work and covering your ridge will have minimal positive impact.
Bryce For clarification; I was not suggesting he close off the ridge vent but that he cover the clear ridge cap. It would be difficult to close a continuous ridge vent even if he wanted to because of the nature of ridge vents on steel buildings. The flat ridge cap attaches to the high spots on the profile of the roofing panels. This create spaces between the low areas and the ridge cap that act as a vent. The spaces usually have a breathable, heavy matrix material that matches the roof panel profile installed under, and along the edge of, the ridge cap. The matrix allows heat to escape but excludes insects.
