Please post photos.

Is this the front or the back? To me, it appears to be the back. The so called driveway is lacking in direction as to where a visitor should go. I would work first on cleaning up the outside before I worried about changing the siding or roof. Those items by themselves will not help the curb appeal.

The photo appeared. Please tell us about the history of the house. It looks like it may be a farmhouse in the vernacular style with alterations over the years. Have you been to city hall or local equivalent to get copies of the permits issued for changes or the original plans, if available?

As most always is true, landscaping works wonders.

At some point in time you will be asked, "What is your budget?" If you do not know it now your should soon.

Waiting for answers .

Is this the front of the house? Is the dirt at the front your driveway or sidewalk? It seems pretty, uh, casual.

The very first thing I would do is to paint the window trim to match the siding. As-is, the trim highlights the windows’ random sizes and placements. Not in a good way.

Same for the metal or plastic conduit running up the side of the house. Paint it to match the siding.

The farmhouse’s style and the treated-lumber (or maybe cedar?) decks don’t play well together. I’d figure out some way to blend the decks with the house.

When considering the price to offer, I would have reduced my offer to include a roof color change. No reason to live with something I didn't like. That's just my aesthetics.

I like the colors. I would paint the gray utility thing white, to hide it. I would clean up the edges of the driveway and parking areas and add landscaping. If the thing between the garbage bin and the right porch is doors to the basement, I'd paint them green or white.

For landscaping, I'd start with some low shrubs or perennials at the edges of the porches and a small, pretty tree in the grass in the foreground.

Besides changing the roof color, I'd use enlarged where possible fiberglass casement windows and change the siding color.

Beverly FLADeziner has given you a wonderful inspiration photo. I would go in that direction. Changing the roof color will not be enough to relieve the boxiness of your home. It's going to take some thoughtful changes/additions such as beverly presented.

I like the white siding with the green roof. I would replace the 2nd floor windows to make them all the same size and make a nice wide frame on all windows. I would unify the 2 porches into 1 and install a nice country style railing. Replace the sconces for black barn style ones. You can also work on a simple country looking landscaping for the grounds.

@lisedv that looks wonderful. Perfect design and not a huge budget buster.

Look at videos on the YT Metal Roofing Channel. Including "Can a homeowner repaint their metal roof". If the metal coating isn't showing rust, you can diy the change to a color you'll like. 10-25 year life before recoat.

That would be my first step. You may choose to have a pro do this at a higher cost.

That metal roof was major money. No seller is going to 'change the color' for a buyer. A porch addition does wonders as Bev shows. The back yard deck look vs a proper porch is never an appealing loo on the front of the house. It's why there is more than one comment asking if this is the front or back. lisevd shows what a change can result just by dolling the standard deck up a bit. A proper railing does wonders. After the porch the landscaping and driveway need addressing. It appears the yard has been neglected for some time. The more extensive change would be to get the slider to the side of the home vs the confuseion of two doors. A slider on the front of the home is never a good look. I see there is a picture window just around the corner. Assuming this is all the same room on the inside perhaps swapping the two would be possible? Changing windows to improve the facade is not as easy as one might assume. How they function for the inside is really more important. Walls, doors, built ins all come into play when you are enlarging or moving windows.

No one anticipates a seller changing a roof color or changing the siding. As a buyer you determine what changes you need to make to a property before you make your offer. That happens with every house a buyer looks at. A normal one.

Painting a roof is a bad idea. In theory, it will last, but will it in practice? It depends on the existing coating on your roof, the rain and snow fall, the quality of the prep job, etc, etc.
