$ 350.00 sounds to me like a decent jumping off point… I’d take the work, but I’m in Austin & am not going to Houston.
I’d be charging about $ 100.00 more if it was a 2 story; much rather see that near the ridge 'cause it would be a much faster repair vs. tuck headlaps under reveals. Also, you’re looking @ 1 bundle of shingles, no more… should be able to do a Ãƒâ€šÃ‚Â¼ piece of ply for the repair; do the deck a favor & add some new wood along the rafters so you get some reinforcing along this narrow section of replaced decking.
The pitch seems to be around a 9:12? Hard to tell by any photo, but this one has me thinking that’s about right. An eave fix is going to involved more ladder work than something higher up in field. Then again, no toe boards & a more solid way to work if you ladder up some boards for a catwalk.
Let’s talk about WHY you have a leak… it is very unusual to see a leak in field. Was there a tree rub? Something had to damage it from the exterior; is there a valley on the other side of this decking?
Also, if the shingles are more than 6 years old, you will NOT get a color match that’s going to look blended, so get on with life right now.
That’s my take on it.
Oh, & we have a recent contributor here who is in the Houston (NE, anyhow) area. Granted, from Austin to Sealy (Western suburb of H-Town) might take less time than from Highlands to Sealy. Traffic is a major pain. I’d rather go 50 miles out of my way than to drive through Houston…
