Some things are best without attention drawn to them......
Just keeping it real!
There are some great painting ideas at http://www.benjaminmoore.com/en-us/for-your-home/exterior-de
To effectively answer this question you should take into consideration the landscape surrounding the home, the lay of the land and how the property sits in the environment, and the colors of other homes in the neighborhood. Is there lots of light around the home or is it shady? Does the home stand by itself or is it tucked behind trees and rolling knolls? Are the neighbors homes muted, bright, dark, etc? If you have a green roof, you will want to pick a similar or complementary colors for the siding. A three color scheme works very well. With the front door one color, the siding another and the trim a third.
I have built a ton of homes for many different people and I can only remember putting green shingles on 2 or 3 times! I happen to like the look on certain homes as long as the green is on the darker side and the siding and soffit and fascia complement it, whatever you do do not put the light green shingles on it will stick out like a sore thumb and you will have trouble with resale! It also depends on your surroundings, if you are on a lot with good tree and vegetation cover it would fit in much better than if you were in the middle of a development with no cover, I had green on my last home that I lived in which was surrounded by a big woods and the home look absolutely beautilful with a green roof, my neighbor where I live now (a home that I built) has a green roof and green surroundings and I think it looks gorgeous. So there are a few factors you should take into consideration before pulling the trigger but one thing you could do to help decide is drive around a few communities and look for the colors you want to use and see how it looks on someone elseâ€™s house before you spend the money to put it on yours and you may spot other colors that you may like better. I hope this helps! Good Luck!
Here-here to Cameron's answer! To elaborate of the color choice......NEUTRAL, NEUTRAL, NEUTRAL with CLASS...is the answer. You want to attract the widest range of possible buyers loving the exterior of your home. Curb appeal is the FIRST and lasting impression they will get when approaching the house. This does affect the reactions they feel as they walk into the house. If you have a unpalletable color outside, you can guarantee this "bad taste in their mouth" will carry through to the interior expecting and LOOKING for more bad taste and reasons to bid lower or not at all. It's hard to give you an actual color without seeing your home and the neighborhood. You want to stand out as the best but not the obnoxious. If you have not signed on exclusively with a realtor, you can send me pic's I'd love to help you out (if you're signed on, by law, I can't step on toes). Be sure to neaten up/pull/weed/trim the front landscape also.
In the metro area it has become somewhat of a beauty contest when you are expecting the highest value in the shortest amount of time, otherwise buyers may expect fire sale prices. Buyers can afford to be choosier, drag their heals and expect a more finished home in the price range they are looking for as the market inventor is high. The Beauty Contest is more important inside with staging your home, ask your realtor for suggestions, sometimes it becomes disheartening to a seller with honest opinions, but remember to look at the SOLD sign instead of the FOR SALE FOREVER sign and appeal to the widest range of potential buyers. If you have a good realtor in the Twin Cities this should be part of their package of preparing your home for sale inside and out, advise or even providing staging consultation, etc.
As for the ROOF: If you meant green, as in the color....run far from this...and fast. Put in a mixed neutral, darker than the siding color, that compliments a pallet of colors so if the buyer chooses they can change the color easily. Be sure the colors fit the style of your home, ask your agent if they are savvy on design or as Cameron stated, pick pre-chosen colors from Home Depot to compliment your siding. Your front door can stand some color if the screen door shows it nicely or no screen. If your home doesn't offer a lot of high end inside, it may be wise to boast all the NEW exterior upgrades in marketing. Don't go overboard on the "green - earth" end yet, I don't believe you'll get the return on your investment on the sale at this stage of the game, this may depend on the value of your home too. In my experience, some new home buyers tend to overlook the roof unless it's in obvious disrepair or the age is pointed out by the realtor, note: in higher end homes it is expected to be in good shape for the most part.
Long and windy, but hope this helps you out. Any further questions just email and I'd be happy to help you out.
Take care and good luck to you!
The color to be used is far contextual than anything else. A good place to start might be to look through the color palettes for Behr (or insert brand name here) paint at The Home Depot. Try to pick a palette that will look good on your house. Whatever you do, don't mix and match the colors, they have been selected to work together and compliment one another.
"Green Roofs" can mean two different things these days. Green (the color) shingles is what I presume you are talking about and again it will depend more on the overall package of the home. Shingles are very expensive to replace if you are simply trying to change the color and chances are slim that you will return dollar for dollar what you spend.
"Green Roof" can also refer to a type of enviornmentaly friendly roof primarily used in commercial architecture. Unless your house is ultra contemporary I would not even consider this type of roofing system and even then only if you really care a lot about the enviornment.
I hope that helps.
