Back in April we installed the 2×6 tongue and groove roof decking and put down some felt paper to provide some waterproofing until we could get the materials together to complete the roof.
A very wet end of April and beginning of May kept us from the work until a couple of weeks ago. The cabin’s roof system is fairly complex incorporating several layers including exterior rigid foam insulation and venting elements. Check out my previous blog post that has a graphic showing each layer.
Here’s the a time lapse of the roof install:
Here are some stills with more detail:
 |
| Building the insulation blocking in place. This is essentially a 6″ tall perimeter wall build to contain the rigid foam insulation panels. |
 |
| The insulation came in 4′ x8′ x 3″ thick panels. |
 |
| I was able to use the ladder as an inclined plane to push the panels up to wear I could reach them from the roof. |
 |
| After getting three or four panels up on the ladder, I could climb up on the roof and pull them up the rest of the way. We used about 40 panels. |
 |
| Positioning the first insulation panels |
 |
| Ultimately, we were looking for 6″ of insulation so I stacked two layers of the 3″ thick panels alternating their orientation. |
 |
| I cut the end pieces to size with a largish boning knife. |
 |
| I covered the insulation panels with 1/2″ plywood securing the plywood to the rafters with 8″ screws. |
 |
| Cutting of excess plywood. |
 |
| Laying out synthetic waterproof underlayment over the plywood. |

| Jean gets a call on the roof |
 |
| We assembled the fascia board with vent strips on the ground |
 |
| Installing the first fascia board |
 |
| To hold the fascia boards in place we attached temporary 2×4 hangers |
 |
| Installed vent strip and fascia board |
 |
| Installing the purlins on a 45° angle to the roof. |
 |
| Air will flow through the lower fascia vents up between the purlins and out through the upper fascia vents. The purlins are laid at an angle to provide a better bearing surface for the metal roof panels. |
 |
| Fastening the purlins to the roof deck with the 8″ screws |
 |
| Installing metal trim |
 |
| Here’s a standing seam metal roof panel that we used. It’s 24′ long and 16″ wide. |
 |
| Installing the first roof panels |
 |
| Paul had a wardrobe malfunction early on in the day but wanted to get one more panel on before heading down. |
 |
| He was able to fabricate some somewhat acceptable shorts replacements |
 |
| Originally, I was concerned with how we could get the panels up to the roof without bending. Lashing two panels together and having two people hoist them up worked really well. |
 |
| Attaching the clips to the purlins |
 |
| Roof complete! |
 |
| Now we have a slide |
I have to say that the first photo has to be a winner of the competition "What my wife and I did this week". It could also be the best entry in a caption competition — What did his wife say to him whilst he was suspended by the ankles???
The roof construction is just as impressive as the whole build ! So very thorough , and clearly carefully planned to be built mostly single handedly !
My first caption competition entry is — Yes I promise never to suggest again that it might have been better facing the other way …
X Tom.
Brilliant
Good job Jean is a mountaineer (BUM)
Looking great guys!. Interesting to read about the roof construction with the air flow between the purlins! Video is great!
