October 5, 2019 – Looks like nice weather today. We will be working on the plywood roof decking and felt paper on porch roof, section three. My Tinnler Roofing crew is here doing some shingle demo, taking off old siding and relocating termites. Should be a good day!
Yesterday, before arriving at the Cot-Taj-Mahal I made the obligatory trip to Lowe’s for supplies. I got twelve sheets of plywood for the roof decking and three rolls of 30lb felt paper.
The plywood roof decking installation went off without a hitch.
As I was installing the decking my peeps from Tinnler were stripping the shingles off the last roof section and putting them in the dumpster. It was a well coordinated endeavor.
After the plywood was complete, I rolled out the roofing felt.
Working into the evening I covered the entire section. Before coming down off the roof I had to dry in the last section with the blue tarps. We are expecting rain tomorrow and I’d like to keep as much of it out of the Cottage as I can.
It was indeed a good day. We managed to finish the third section of the porch roof. Only one section remains and then we can put on the metal roofing. The deck is looking bigger and better every weekend.
September 29, 2019 – Rinse and repeat day two. The roof framing in section three continues with the installation of the second span roof rafters.
First I remove the top rows of oak roof planking to gain access to the ridge board. Next I connect the new roof rafters to the existing ridge board with galvanized rafter hangers. The hangers are Simpson Strong-Tie adjustable 2×8 hangers.
The opposite end of the second span rafter sits on the mid span knee wall. It is nailed to both the knee wall and the first span rafter.
Eleven rafters complete this section. As always, the last thing that needs done is placing the blue tarps to keep everything nice and dry until next weekend.
Next weekend I will install the plywood roof decking and cover this section with 30 lb. roofing paper. After that, it is on to the last section, section four. Hip Hip Hooray!
September 15, 2019 – Porch roof framing in section three continues today with the installation of the ceiling joists. The joist installation process is the same as it was in section two so I’ll keep this post short.
After setting eleven ceiling joists in section three I started the solid bridging installation.
I ended the day a little early so that I wouldn’t be to late getting back home. Next weekend the porch roof framing in section three will continue. I will be finishing up the solid bridging and starting on roof rafters.
September 08, 2019 – Today is renovation day 100. A milestone? Anyway, we continued the exterior wall demo in front of the bathroom. Late in the day I was able to start the roof framing in porch section 3. It was a pretty good day.
There is no more wood rot in the front wall! This morning Ryan and Robrandi removed the siding from the exterior wall in front of the bathroom. All of the oak planking in this area looks good. The last section, along the back bedroom was repaired way back in June of 2018.
I forgot that the deck spans as we near the back bedroom are slightly greater than 8 feet. One is 8′-8″ and the next is like 8′-4″. I previously purchased 8 foot long 2×10’s to use in the porch beam construction. Obviously they are short and won’t work. While Robrandi and Ryan headed to out to get me some longer boards I continued the exterior wall demo along the bathroom.
When my team returned with the longer 2×10’s I built the next two porch beams. We installed them atop the next set of posts, plumbed them up, braced them off and called it a day. Next weekend I’ll start the porch ceiling joists and solid blocking.
September 07, 2019 – Up early this morning. Lots of fog on the river. After our morning coffee at the lookout, I continued the plywood roof deck installation that I started yesterday.
The new roof has a low pitch so the plywood roof deck is not difficult to install. The hardest part is getting it up onto the roof!
Although not show here, between each row, I place metal deck clips to help support the plywood edges.
I like to chalk line the rafter locations so that I know I am hitting each rafter as I nail down the plywood. Not every carpenter does this, I’m just anal.
Early in the afternoon I finished the plywood decking and immediately started to roll out and nail down the roofing paper. Because the first roof section we completed had 15 lb. felt I rolled a layer of 30 lb. felt over top. We had a pin hole leak at one of the plywood deck joints.
I worked a bit late but managed to get the entire section covered with roofing felt. We now have two porch roof sections dried in. Tomorrow we will start the third section. Hoo Raw!
September 06, 2019 – Yesterday I completed the roof rafter installation on the first span. Today I am continuing the roof rafters on the second span. The second span runs fron the mid span knee wall to the ridge of the existing roof.
The roof rafters in the second span must connect to the existing ridge board. In order to gain access to the ridge board I need to cut and remove sections of the old oak roof planking. With the planking removed I can fasten the new rafters to the ridge with galvanized joist hangers.
Tinnler (Tinder?) Roofing
As I am installing the rafters, one of the “Tinnler Roofing” employees is stripping the shingles from the next section of roof. Man that Tinnler (Tinder) Roofing is really great! I think their slogan is “Get a Date and Go Up On a Roof” (or something like that).
With the rafters in the second span complete, the plywood decking can be installed. To cover this section of roof we need 12 sheets of plywood. Since we are not keeping a large stockpile of material on site, once again we are off to the Lewistown Lowe’s.
We got back with the plywood but the sun was on the way down. I only got two sheets installed before we had to quit for the evening.
Tomorrow I will complete the plywood roof decking and hopefully the roofing felt. This will dry in this section and we can move on to section three. When this section is complete we have two more identical sequences to finish the new porch roof. Our goal is to complete the roof structure and hire a “real” roofing contractor to install the metal roofing material. We will see how that goes.
September 05, 2019 – The ceiling joists are complete. The next step is to construct a mid span knee wall to help support the roof rafters. Our roof span on the new porch side is 24 feet. The midpoint of this span is at the exterior wall of the cottage. The mid span knee wall is constructed on top of the exterior wall. Simple as that…
I build the knee wall framing on the ground on saw horses and then I hoist it onto the roof.
Once the framing is plumbed up and nailed into place, I face the knee wall with 5/8″ exterior grade plywood to keep it square and help stiffen it up.
At this point I am out of lumber so I cover the roof and make a make a quick trip to my favorite store, the Lewistown Lowe’s. Be back soon…
Whew, I’m back….
With the plywood facing complete, I begin setting the roof rafters in place. The first span of rafters run from the porch edge beams over to the mid span knee wall, atop the exterior cottage wall.
I continued setting the first span of roof rafters until it was time to clean up and grab some dinner.
As always, before I left, I closed it up for the night.
Tomorrow I will install the second span of rafters. They will run from the mid span knee wall up to the ridge board of the existing cottage roof. Nearing completion on the second roof section, exciting stuff!
September 04, 2019 – Just a short blog today. Woke up this morning feeling tired. Not sure what is going on. Maybe it was the constant up and down the ladders, but the only thing I accomplished today was the installation the of the ceiling joist solid bridging.
Solid bridging provides lateral support to twisted joists and it helps them maintain a vertical orientation. It also facilitates load sharing. Load sharing across wooden joists is important because of the large variation in material properties found between the joists.
The first step is to set, plumb and brace the 4×4 Douglas Fir posts. These support the edge beams which in turn support the ceiling joists and rafters.
Next, the edge beams are constructed from 1/2 exterior grade plywood sandwiched between two, 2×10 boards. Panel adhesive and 16 penny nails, on both sides, join the beams together.
Once complete, we lift the beams into place on top of the Douglas Fir posts. G90 Galvanized wood to wood wall ties keep the beams aligned and together.
2×6 ceiling joists are next. The ceiling joists span from the exterior living room wall out to the porch beams. They will hold up the porch ceiling.
With the daylight waning I set the last ceiling joist of this section and cleaned up for the night. Tomorrow I’ll continue the porch roof construction with the installation of the solid bridging between the ceiling joists. See you then…
