In part four of the workshop Design/Build video series Bozeman, MT Contractor Peter Brown looks at the back patio roof construction as well as some finish detailing issues with regard to siding and trim.
Patio Roof Details
The entire patio roof assembly had been pre painted on site. The roof consists of 4×6 rafters with an exposed layer of painted T&G pine. The pine is covered with a layer of OSB that will stiffen the roof, keep roofing nails from poking through the pine below, and hide electrical conduit for a ceiling fan. My client had expressed a desire that the roof connection to the main building not have a ledger detail with exposed hangers.
A solution to this situation that I have used in the past was to insert the 4×6 joists into the wall and attach to an interior ledger. Each joist was secured with (3) 6 inch structural screws. A metal strap attached to the top of each rafter and nailed through both layers of decking wraps over and down the interior ledger securely tying the roof to the building. The result is a very tidy roof attachment at the wall.
Belly Band
Our push with regard to siding is to get the high work done first so we can return the rented lift. Out of necessity, this requires a flashed and weather proof belly band detail that is set away from the wall surface and will accept the lower wall siding to be installed later.
Siding Issues
Other siding issues that are a carpentry challenge are round top windows and the roof to wall areas of both the shed and gable dormers.
We made a template of the round windows. After installing the round top windows this template helped produce accurate and tight siding cuts around the windows. The window detail requires that we carefully caulk the seam. We also caulk any nail heads that break the paint layer. This type of siding material requires that any cuts exposed to weather be well painted before installation.
Siding both the gable and shed dormer roof to wall transitions is always a challenge.
A clean and efficient solution for this situation was to make a pattern and pre cut the siding. Since Brown had done the original drawings myself in CAD, he was able to go back and find the data points for this obtuse triangle. These data points produced an accurate pattern allowing the precut the siding to fit well. The extra time in template calculation and layout allows a very clean finished look.
This video shows the average homeowner some examples of common but problematic architectural details and the onsite carpentry that goes into skillfully executing this type of work.
Hello Peter,
Nice talking with you the other night. I finally had a chance to watch your latest video. What a good job! I’m impressed at the skills you show and the quality of the detailed production. I found it very understandable and professional.
It reminds me of a show I once did called, “The Ultimate Sportsmans Lodge”, for the DIY channel. We followed the complete construction process from start to finish and I learned a lot just filming the various elements from laying the foundation to mounting trophies in the beautiful home.
I’m sure potential clients are impressed when watching one of the video’s. I would think it helps to secure the deal.
Cheers,
Randy
