Bob meets with Ed Weller and looks at the roof flashing details. Bob reviews the various pieces involved in flashing including the drip strip, fascia, felt and roofing nails.

The western red cedar decking is complete on one side of the house and Tim Berky, the general contractor, is completing trim on the oriel windows that face onto the deck. Berky begins by covering the existing board with MDO (medium density overlay) to create a new surface over the underboard, an ice and water barrier, and copper flashing installed to keep water away from the house. Berky then installs corner dressing to trim out the outside of the window base. At the top, he will apply two layers with casing and corner board that he nails into place with a nailgun.

Bob joins Charlie on the third floor of the Medford house where he's installing an ODL tubular skylight. It's a pretty simple do-it-yourself project. You just cut a hole in the roof and assemble the parts. So far Charlie has made the hole in the roof and installed the flange that sits on top of the roof. It's one piece so there is little chance of water coming through and there is no step flashing involved. Next he installs the reflective tubing through the flange and attaches the solar lens within an acrylic bubble that tops it. He then attaches the tubing that goes through the attic space and tapes the pieces together with reflective tape. The 14-inch diameter tubing is articulated so that it can bend a bit to adjust for framing elements that might be in the way. Charlie has already cut a plywood collar for the tubing which will screw onto the drywall. When the ceiling is plastered he'll finish the job - attaching the interior flange and the trim kit - creating the appearance of a light fixture - only without electricity.
