I'm pretty sure you'll get tons more signal outside. Try an experiment: If you've got some scraps of wood laying around, build a model "attic" with similar materials to what you have overhead... eg. a box made from 1/2 inch plywood covered in spare shingling. Compare signal strength inside and outside the box. Or get a broom, put the antenna on the end of the handle and hold it out the window. Compare signal strength inside and outside your attic. You could possibly even avoid serious drilling by making a small cable pass-through somewhere.
