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.

Because of the time of year the openings were tarped every night to keep the snow out of the home.

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.

Roofing & Rough-In Stage Complete – Priceville Farmhouse Renovation
With rough-ins complete, we’ve now installed a full architectural shingle roofing system on this Priceville farmhouse restoration. We used GAF Timberline lifetime shingles for durability and curb appeal—ideal for this one-and-a-half-story heritage home in Grey County. Six feet of ice and water shield were applied in all eaves and valleys, with synthetic felt paper protecting the rest of the roof. Steel valley flashings were installed for added long-term performance, ensuring this farmhouse roof can handle another century of Ontario weather.
We also added a concealed vented ridge under the ridge cap, creating a continuous airflow path that doesn’t compromise the roofline’s traditional look. These roofing upgrades are a key part of restoring older farmhouses—tying modern protection into classic forms. As the general contractor on this project, JCB & SONS is managing every phase of this full-home renovation near Markdale and Durham, from structural framing to waterproofing and finish.
We also installed almost 400 brick ties in the old home tying the old structure into the new structure we built inside of it prior to polyurethane foam insulating.
We took the time to drywall the ceiling in the addition prior to insulating. We than had 2" of foam insulation sprayed over the drywall, potlights, speakers, etc. We will top this up with cellulose to achieve an R-50 in the addition attic. This ensures an airtight seal around all the fixtures and against the exposed brick wall between the old home and the addition.
We added this Pent Roof over the living room window which looked out of place prior to the renovation because it was added later and not trimmed the same. All the openings in the brick have arches except this one. This added an element of curve to this window, it should also tie in well with the future porch around the addition.
The addition foundation was cement block and leaked badly all the time, especially in the spring or after rains. We excavated around the foundation to waterproof it. We pressure washed the old foundation as well so the waterproofing would bond to a clean surface.
Hydro One came in and disconnect power and installed the new underground cable from the hydro pole at the road to the new meter base WireQ installed.
WireQ installed a disconnect switch to add in a future back up generator as well as a new 200amp breaker panel.
During excavating we found the missing well, which is illegal as it was below grade and would have run off going in the exposed well head. The cement block foundation had a lot of cracks. We V'd them out with a diamond blade and filled them with non-shrink grout which was than coated with fibreglass resin by MBS prior to tarring it.
We installed new septic tank risers on the old septic tank to make locating and cleaning the tank easy.
We eliminated the old sump pail by digging in this trench and installing pipe for the weeping tile and a separate pipe for eavestrough creating a french drain to remove the water far from the foundation.
The front door sill was all gone and rotten. We poured in a new cement sill after having the ring joist coated in spray foam first.
sprayed all the walls with R-24 spray foam, the old house sloped ceiling received R-50 spray foam and the addition received R-12 spray foam and will be topped up to R-50 with cellulose.
Martins Insulation insulated the basement walls with R-24 Spray foam.
We tied the new weeping tile into our new french drain, which we also installed a cleanout in just in case. We ran a separate line than to tie the eavestrough into.
We than backfilled the foundation with 2' of washed stone and than gravel on top to ensure great drainage around the foundation as the property does slope into this home.
The white pipe on the left is the cleanout for the weeping tile ensuring it can never plug. The white pipe on the right is for the future eavestrough to tie into. Keeping the water away from the basement.
