I don't know of anything outside a custom built solution that would be
able to achieve that...
Here's what you're dealing with:
1. GD or ImageMagick Support at a minimum. GD is required by WP but is
not nearly as powerful as ImageMagick OR Flash (which has powerful
filters built in).
2. Some way to predefine, have the user select, or auto-detect what is
house/roof and what is not (no easy task, unless you have an artist
doing it in Photoshop and letting the user select from a list of
photos).
3. Algorithms to attempt to change the color cast of the source photo
(masked to just change the house paint/roof) to match the target color
-- if you're starting from a known point (i.e. you provide the photos)
that's doable, but if you're using customer supplied photos it's a
pretty daunting challenge to have any semblance of accuracy. And then
you have to take into account ambient lighting in the photo (which
causes us to perceive colors differently).
If you client has a preferred paint brand (or doesn't mind linking to
one) they might be your best bet. Most big paint brands have a tool
like what you're looking for, and I guarantee they paid dearly to have
it built.

However, I think it can be achieved without great difficulty if you
allow the use of either HTML5 canvas or Flash.
here are my thoughts.
1) create an image with the roof cutout (photoshop).
2) place html5 canvas image (original) with roof-cutout-image on top
(separate div).
3) use a javascript-color-adjustment algorithm to modify the color to
your choosing.
Your greatest challenge will likely be the color calculation to derive
the proper values.
If so, you will need to measure the paint or roof material with a
spectrophotometer or a spectroradiometer to obtain the correct CIE
L*a*b* values.
If you are going for the "eye-ball" method, photoshop might provide a
good enough estimate output result. Then you can just load those
different images created in photoshop.
What do you think ?
Here is my Flex implementations in HSV and CIEL*a*b* adjustment.
Maybe this is useful to you (port to javascript)?

Oh, I was experimenting with sound and interface sometime back.
Did you grow up with Atari too?

Thank you for sharing the Sherwin Williams website. The user
experience is way cool.
It looks like the color selection is being applied as a transparency filter.
But as you probably know, paint is a pigment that reflects light (not
transparent). So I am not sure how they are able represent their
products accurately.
If you wish to approach this in similar fashion, you can obtain the
CIEL*a*b* value for each paint selection from your client (or measure
with a spectrophotometer) and calculated the corresponding sRGB (HP)
values for a standard monitor. You may need to do some guessing on
the scene light source (daylight, tungsten, fluorescent, etc) for the
final image.

Something that might be of value to you in lighting and color
calculation for architecture.

and not too expensive. His name is Jake, he built the functionality of
the "preview your look" page of this site we did together--

me know and I'll send it off-list.
Good luck, sounds like a fun project!
