When it comes to setting up a trellis on the eaves of a house or garage, for those of you (myself included) who know nothing about roof construction, i thought this might be helpful, as i've done some searching and couldn't find any related info.
I had originally intended to secure an eye-bolt into the soffit area, until realizing that, depending on the construction, that area could actually be "hollow" and unfit to bear the weight of a trellis system. So, at this point i plan on installing eye-bolts into the underside of the fascia board through the fascia cover, as i've depicted in the diagram. Additionally, i do plan on adding clear silicone sealant in order to provide water resistance.
Does anyone who's done this type of work see any problems with this process?
