CLEARSTORY WINDOWS  •  DECK OVER ROOF

 

CLEARSTORY WINDOWS

Clearstory windows are a popular way to let light into a home without using skylights. However, much of the time, partially because they face south and partially because of poor craftsmanship, they leak. This leakage appears to be a roof leak usually. So when I re-roof a home with these windows I like to strip the woodwork around them and re-do them completely. In this first picture you can see the stripped wood area around the window.

One of the most critical parts of this project is to get the new roof to wall flashing under and behind the actual window frame. Once done I can begin the flashing, sealing and re-installation of the wood trim. I have more detailed pictures of the entire process available if you like. Please write me and I can e-mail those to you.

Here you can see the finished job, new flashings, wood trim etc. One of my employees suggested we put a Z-bar flashing above the windows to make it even more watertight, and it came out very nice.

 

DECK OVER ROOF

In this situation the general contractor wanted to put a redwood deck over a" Dibiten" torch-down roof. To insure that the deck would not have to be removed for a long time we decided to do a double layer of Dibiten torch down roofing. In the first picture you see the fiberglass base sheet to the right and the Dibiten being rolled out to the left. The base sheet serves to protect the plywood deck from fire during the torching process.

Here you see the mostly completed first layer, except for next to be installed roof to wall flashing at the extreme right.

Now the first layer is down and you see the roof to wall metal in place. We used copper because we don't want premature metal failure at such a critical location. You can see the second layer in place on top of the metal (creating a sandwich of the metal) awaiting the final sheet against the wall.

This picture shows the second layer of Dibiten being torched on. When done perfectly there is a "ooze" of material that flows out. We say "ooze is good". When we don't get the ooze desired we just follow behind with a smaller torch and detail the seams.

The two ply roof is now complete. At the threshold of where the sliding glass door will be you see we've bent the copper down for the slider landing to rest on making yet another very critical connection to the house. This roof system should last 30 to 40 years. Later during construction this roof surface will have a redwood deck installed on it by the general contractor.
