Roof Framing & Dormers – Eco Log Home in Berkeley Near Owen Sound
On this Eco Log Home project in Berkeley—just south of Owen Sound—we completed all roof framing, including the structural dormers, insulation build-ups, and ventilation layers. Working as the builder and carpenter on this rural home, JCB & SONS brought precision framing and timber craftsmanship to every stage. From engineered roof structures to insulated envelope details, we supported the homeowner-led build with skill and care. Projects like this highlight the kind of high-quality carpentry and roof detailing we provide throughout the Owen Sound, Berkeley, and Markdale region.
2”x6” dormer walls set and ceiling joists placed on 16” centers.
Laying out for the collar ties that will be installed.
Because of the time of year the openings were tarped every night to keep the snow out of the home.

First half of the roof completed and ready for the future steel roofing.
Walls set on the second half of the roof for the last 2 dormers going on.
We are a family business and everyone pitches in. Alisha came in to help make sure our site stayed safe and clean for us.
The hemlock ceiling boards where all left long until the end on the gables. This allowed us to snap a perfectly straight chalk line to cut them too. We were able to manipulate the 4” x 10” trusses then to follow our perfect line keeping the ends very straight and clean looking.
The roof was made up of multiple layers. First the 1” x 6” hemlock ceiling boards went down. Then a synthetic roofing membrane was installed with ice and water shield in the valleys. Next we installed two layers of Styrorail insulation. A base layer of 3” SR.P200 Graphite which can’t stay exposed to any sunlight and then a second layer of 3.5” SR.Radiant+ which has a vapour barrier reflective membrane laminated to it. All layers have offset joints which where taped with Tuck Tape sheathing tape. We then cover the valleys & dormers with an additional layer of GRACE Ice and Water Shield HT. Finally all this is covered with a layer of 2x4 sheathing installed @ 16” o.c. for the new steel roofing.
Over the balconies at the gable ends and the porches we used a 2x8 rafter build up to match the 6-1/2” of insulation and then installed the 2x4 sheathing over top of them @ 16”o.c.
Completed jack rafters forming the valleys of the home with collar ties installed to prevent any uplift or separation from the roof peak.
We pulled some large tarps over the home at the completion of our work to leave the home ready for the new steel roof install.
Exterior Finishing & Windows – Heritage Log Home Renovation, West Grey
As part of this Priceville-area heritage log home renovation, we completed the exterior finishing on a newly built addition. We installed vertical engineered wood siding and fabricated custom aluminum trims in-house to ensure a clean, durable fit. A synthetic roofing membrane was applied prior to final roof installation, and all new windows and doors were supplied and installed by JCB & SONS. Each unit was carefully flashed with waterproof tapes to guarantee long-term performance in Ontario’s harsh climate.
The existing porch was reworked to tie seamlessly into the new structure, and extended to shield the original log walls from weather exposure. This project combined renovation, new-build construction, and precise exterior finishing—hallmarks of the kind of heritage carpentry and rural craftsmanship we bring to homes across West Grey, Priceville, Durham, and Markdale.
The log home had a fantastic view from the second floor, so we installed these apex shaped windows in the gable wall of the home to take advantage of it. It was one of our favourite features.
John Manville AP foil-faced 1” foam sheathing was used for the wall sheathing to provide continuous insulation over the whole addition. Providing and R-28 wall with the Rockwool batt insulation.
Prior to the install of strapping and siding we installed new Typar weather protection barrier over the existing exterior walls to protect the homes exterior.
The walls were all strapped with 1” strapping to create an air space behind all the new siding.
All the windows and doors were clad with aluminum trims we manufactured on site and installed prior to siding installation.

Framing a Heritage Log Home Addition – West Grey Builder
Framing is now complete on this heritage log home addition near Priceville, in the heart of West Grey. JCB & SONS served as the builder and carpenter on this rural home improvement project, handling slab layout and full structural framing. The new space ties into the original log structure and will house mechanical systems like the HRV and high-efficiency furnace, while adding practical year-round storage. This type of log home addition—solid, functional, and built with care—is exactly the kind of craftsmanship we bring to heritage renovations throughout Markdale, Durham, Flesherton, and the surrounding Grey Highlands.
Ethan Bender from Acewood Carpentry was an integral part of this project and was with us from start to finish.
Our Branson is on site with JCB himself and used to safely handle and place materials for this project. Ethan is prepping for installing rigging to set the 40’ LVL ridge beam.
The 40’ 3ply LVL ridge beam is in place with the middle column installed ready to receive the first of our rafters.
JCB cutting our rafters and placing them on our Branson to lift them into place.
Rafters are set higher then the ridge beam to allow baffle vents to run continuously from the vented soffit at the eaves to vented ridge cap at the peak, preventing any ice damming on this roof.
Fascia board lookouts are installed and gable Fascia is started. Almost ready for sheathing.
The roof was sheathed with 5/8” plywood and covered in a combination of Alco ice and water shield as well as Rex synthetic roofing underlayment.
The bump out window roof sheathing was left off so that the spray foam insulators could spray closed cell foam in it while spray foaming all the rim joist in the new addition. These areas are difficult to seal properly with other insulating methods.
The 2” x 12” rafters provide maximum space for storage in the new attic as well as room for insulation and ventilation allowing the correct R value required to keep this home cool in the summer and warm in the winter and prevent any ice damming.
John Manville AP foil-faced 1” foam sheathing was used for the wall sheathing to provide continuous insulation over the whole addition. Providing and R-28 wall with the Rockwool batt insulation.
The interior is a blank canvas, ready for windows, doors and then removing the old exterior wall to open up the existing home to the new addition. This will become the new kitchen and dining room as well as a main floor master bedroom with walk in closet and ensuite.
