Cutting a slot in roof of Dept.56 bldg. ?

Even with a neatly cut slot, the value of the building is no longer gonna be a factor, So, I would go for it.

The diamond disk should work well. I have not cut a Dept 56 building but other similar things.  Like NYC said keep in mind it will be worth $0 after the mod....but if I wanted to do it...I would. 

If you have a cheaper ceramic building you might want to do a practice cut on that first and see how it works.

I believe the key when cutting ceramic is to let the tool to the work and not try to push hard into it to make it cut faster.  Just a little pressure to keep the cutter in contact with the ceramic is all you need.  And as for losing value... I bet reselling it WITH the sign would make its value go up!  Or you can always just use some drywall putty to seal up the hole and paint over it.  

ouch, can you use a double back tape to hold the sign. Dave

If you are looking for a way to hide/disguise the wires and want to cut the slot in the building for this reason there are other ways. One of my favorites is to hide the wires inside a black drinking straw or coffee stirrer. You can slit the straw lengthwise carefully with a razor blade to avoid having to cut the wires on the Miller sign.Some straws have the "bendy" part built in to turn corners on the building.

With the sign hot-glued or sticky-tacked to the building attach the straw to the building and paint it an appropriate color. It can look like a conduit or downspout. Send the wiring through the layout top and hook up.

No need to cut the building.

Not really concerned with lessening the value or resale value. Really like the Bldg. & would hate to destroy the roof if cutting failed.
