![]() I would be tied into the "drill into one out of every three rafter tail" setup, where two out of three hangers only affix to 3/4" of "meat". This appears to be a more conventional approach, but it comes with a significant drawback for my project - It would eliminate my ability to place the gutter hangers wherever it's most aesthetically pleasing/symmetrical. Idea #3: Sister each rafter tail and cut it square and at full width ![]() This is obviously typically done before the roof is installed during construction, but is there any way to retroactively cut off 1.5" square and affix a 2x sub fascia? The roof is slate, so lifting up a bottom row is not feasible. Idea #2: Cut the rafter tails and install sub fascia Something like this:Īnd nail the 2x4 block to them, and also affix the top two corners to the real rafter tails. The idea here would be to fit a 2x4 in between each rafter tail and secure each end with something like a pair of Kreg Blue Kote outdoor pocket hole screws, leaving the face of the 2x4 flush with the rafter tails. I've been spitballing a few ideas and would love some feedback. I'd love to hear some creative advice here. The problem here is that since the rafter tails are so narrow, some of the hangers might fall in line with the 2x blocks in the pictures and not the rafter tails themselves, or even screw into the seam between them. This led me to thinking that the hangers (which will be spaced 24" apart) can be drilled into one out of every three rafter tails (which are spaced 16" on center), which might compensate for two out of every three only being drilled into 3/4" wood. ![]() Long story short: I pretty much have to use 1x (3/4" actual) lumber for the fascia here in order for all of the water to be collected at all levels of rainfall. The new cast brass hanger pushes the back of the new half round gutter 1/4" away from the fascia, and with no drip edge and the capillary effect to contend with, slow water would just barely trickle behind the gutter according to a hose experiment I did.
