UPDATE: DO NOT use a hinge! It has come to my attention that hinges are NOT covered by ANY of the mast manufacturer's warranties! If you try and expand the mast all the way and then "swing" it up it won't work and will bend in half!!!!! If you are using a hinge, make sure that at least half of the screws that you have used are in a rafter! (I say this because sometimes the center of the roof has no rafters, hence the piece of wood between the rafters).Crawl underneath and make darn sure that the hook has caught the rafter or the piece of wood that you have screwed in place between the 2 rafters!. ![]() Turn the eye hook into the roof - as you do this, you will pull the sealant down into the threads Then un-screw it and squirt a large amount of silicone into it (Not the cheap stuff! Geosill 2000 works great for this - it doesn't get hard). Make a small pilot hole into the roof and then turn the eye hook into the hole.When installing any eye hook in ANY roof, it MUST be in a rafter! If you can not hook a rafter then you have to cut a 2x4 and nail (screw is better) it in place between the 2 rafters so you have a solid place to screw the eye hook into! (if you are in a high wind zone, make sure the rafter you are hooked to has a "hurricane strap" attaching it to the top plate on the structure).When installing guys on a roof or any wood covered surface, you MUST catch a rafter!!! If you don't, you will be fixing it and using your insurance to fix a ceiling!
