Of all the surfaces in a home, the ceiling receives the least human contact, barring the year M.C. Escher and Lionel Richie were roommates. Flatter floors' underappreciated counterparts with today's Groupon to Luxtom Homes. Choose from the following options:

• For $30, you get $200 toward acoustic-ceiling removal in one room.
• For $99, you get $700 toward acoustic-ceiling removal in up to three rooms.
• For $99, you get $1,100 toward a full roofing project.

Luxtom Homes' team of residential construction connoisseurs updates overhead surfaces by removing popcorn ceilings and replacing roofs. Before erasing popcorn from ceilings ($500 plus tax for one room up to 12' x 12' or $1,400 plus tax for three rooms), a skilled technician will drape drop cloths on floors and furniture to catch falling pieces of interior sky, and then test ceiling particles for asbestos (this Groupon is not valid for asbestos removal). After stripping the room's roof down to bare paint, ceiling slayers will clean up and dispose of all debris.

When installing a brand new roof, roofers will first peel off the home's existing tar-and-gravel toupee before slapping on a new and improved one. Though each rooftop renovation is unique, a sample project for a 20-square Pabco architectural composition roof costs $5,900 plus tax and includes a choice of roof color, 15-pound felt underlayment, and all the appropriate flashing, vents, and dump fees. Roof sheathing carries an additional charge, as does covering the roof in reindeer traps.
