Sounds like a great home, but, we need photos. Without photos, my suggestion would be to match the metal roof in color for paintable areas. This color, from B.M., is Gray Cashmere. (It is my suggestion, and not identified in photo). I love it interior or exterior because it acts as a chameleon...

Is ALL the bnb being replaced, or just the dormers? I think that changing the color of the dormers would be enough to change the look. Beautiful house!

Downspouts are one of my least favorite utilitarian necessities, so I'd get them as close to the color of the logs as possible so they blend in.

Donna, my husband and I live in a log home in the N.C. woods. We use and recommend a product called New Again for cleaning your log siding. It is biodegradable, only requires low pressure rinsing, non-bleach and leaves no streakes between cleaning sections. Regardless of the stain/preservative you choose, you will need to clean the log siding of the pollen, sap and dirt before you restain. The company's website is www.newagain-roofndeck.com. I personally like the red on the windows and would apply it to the windows on the upper section of the house. Especially if someone near you already has green. My opinion on the portico is live with it for a bit before doing anything; it does serve a purpose which you might find over time is practical and protective. However, I would consider removing the three bottom rows of log siding in the front to open up your line of sight. It could possibly bring in more light under the portico and the front elevation of the portico would not look so low. Good luck with your new place and enjoy the experience of a log home. We are still in love with ours after 16 years.
