What's the least intrusive way to install flashing where my roof intersects with a wall? Do I need to tear up a bunch of shingles or can simply attach the flashing with something on top of some roof sealant in the valley? I suppose one option is to install the flashing and find a column's worth of matching shingles... how do I find out what the local codes are specific to this?
As you can see, there are old (?) water stains visible on the sheathing inside the garage, though I've never been able to detect any wetness by touch. I should really cut a hole into the drywalled ceiling and take a look around now that I think of it... Would tracing the current stains with a Sharpie be a means to detect if the stains are growing? Should I replace the sheathing as long as I'm at it?
Unfortunately the previous owners must not have noticed (or cared) that the roofers forgot the flashing. Our inspector caught the issue when we were buying the house but I'm just now getting around to doing something about it a year later.
The image of the wet spot on the siding was taken after some light rain. I'm not sure why it's just that one area.
Also, I can tell that the front step adjacent to this wall has been slowly sinking for a long time based on several factors (images included). The previous owners said they changed the grade of the step (after some water got into the crawlspace) so it would slope away from the house "as it should" but it looks pretty crappy to me. This is probably related to the missing flashing, right? Is there a good DIY fix for this?
And I'm aware of the sag in the rafter (though maybe it's just the fascia - based on that cut in it near the peak?) but I have no idea what to do about it or how to determine how big of a problem it is. Is it as simple as taking a look around in the ceiling and I'll be able to tell?
Any tips or advice is more than appreciated!
