You would want to use Dicor sealant under the cleats: ***Link Removed***
I'd use the largest self tapping screw that fits into the holes on the cleats. Maybe 1 1/2" long but you don't want to go thru the roof so that may be too long. Something like this: ***Link Removed***
However my concern is just what do you plan to carry up there, how much does it weigh. That roof is not designed to be load bearing. And I have my doubts about how strong those cleats will be. Don't forget you are going to have the wind load to deal with besides the weight of whatever you carry. At 60 mph that wind load can be substantial.
If I was installing them on a boat I would drill thru the roof and put a metal backing plate in on the ceiling side with machine screws passing thru the roof. Not practical in this case.
The anchors will not be used to carry heavy weights, only to hang tarp off the side, it just has to handle high gusts of wind - that's why I can't use the awning.
thank you for the suggestions.
A followup question: Regarding the Dicor sealant under the cleat, just to clarify, you recommend I lay down the sealant, place the cleat on top of sealant, then drill the holes through the sealant, correct? Do I wait for everything to dry first? Should I apply more sealant after the screws have been drilled through?
