First thing I would do is remove both the tall plants adjacent to the door.

I can’t really tell - is that a small screen porch and your real entry door is inside it? (That looks really odd to me.). If so, I’d remove all the screening and then concentrate on making your entrance doors handsome.

And if you are replacing the roof, I’d get a deeper darker color that would contrast strongly with the body of the house. Deep brown? Forest green?

I agree with removing the rock. Replacing it with brick, stucco or a more organized stone would be a big improvement. You need a new landscape, too. The existing one looks busy and haphazard. If you need to keep the screening at the entrance, it would look a lot better if the mullions were dark instead of white, so they appear as if camouflaged. The entrance walk is much too narrow. The space there should feel more courtyard/plaza-like. Smothering it up with plants -- so that entering is like threading a needle -- is not appealing. Paving that projects outward, as if to receive, would be helpful. It can't be seen, but I'm sure that walk flanking the garage is too narrow to allow for a nice entrance experience and too close to the house to allow for a decent foundation planting.
