A. Yes, an extended drip edge will fit over the existing one; slip the wide flange under the bottom course of shingles; they should lift slightly so you can stick it in place. You could nail it by lifting the shingles enough to drive a nail far enough under the shingle so the shingle covers the nailhead when the shingle is flattened out. If the shingle does not stay put, slather on a little roofing cement between shingle and drip edge as you press it back into place.

Q. The drip edges over my window frames come only to the edges of the frame, and also are bent upward, which does not give much protection from water dripping over them. I have been caulking under them. Will this keep water away?

BARRY STEARNS, Waltham

A. It will keep most of the water away, and if the caulking doesn't hold down the edge, drive a small galvanized nail on the top to hold it down. When you drive the nail, some caulking will ooze out, but that is OK because it indicates a good seal between edge and frame.

Another fix is to buy some aluminum flashing, cut it to about 1-inch wide, and bend over about 1/4 or 316 inch. After caulking the space, slip this new piece under the edge, so you will be creating the proper folded edge. This will work a little better than a simple caulked edge.

Recently Steve Hoar of Andover asked how to move a fairly large and heavy shed from one spot in his yard to another, a distance of about 80 feet. He said he called a house-moving company, who said the job was too small for them. So the handyman suggested he get a bunch of friends to lift it up and move it bodily, as the handyman once saw done with a Quonset hut in Korea some 44 years ago.

Anthony Stanton of Framingham suggested another way, as he saw done some years ago: ``I saw a crew heave a shed up on large PVC pipes, 8 or 10 inches in diameter and used as rollers.'' Good point: As the shed is set on the rollers, and started moving, more rollers are placed in front, and those left behind are transferred to the front. With luck, it could take only a few minutes. Be sure to have some chocks ready to stop the rollers if they get rolling too fast downhill.

And, Dan McCue of Plymouth suggesed renting or hiring a flatbed truck with a platform that can be lowered close to the ground. ``For such a short run, it shouldn't cost more than $100, or at least a resonable amount,'' said McCue. That should work if a flatbed truck could get into the yard.

Thanks, Dan McCue and Anthony Stanton. Steve Hoar might thank you, too.

Q. You wrote some time ago about an aluminum drip edge that can be installed to extend the edge of the roof out just an inch, but enough to allow water to drip properly into gutters. That sounds like exactly what I need. Where can I get them?

DON BOWLER, Watertown

A. Such drip edges do extend the roof line, just enough for water to drip into gutters without backing up, and also to prevent water from dripping down the fascia, taking the place of a 1-by-2 extender board on the top edge of the fascia. They are made by Lamb & Ritchie of Saugus, telephone (617) 662-8015, and Pawtucket, R.I., telephone (401) 723-8860.
