Furring Roof Rafters

If you re framing a gable roof on a new house or building a shed or even a doghouse with a gable roof you ll need to cut a number of roof rafters.

Furring roof rafters.

This gives me 3 5 of foam for a pretty decent thermal break. Cut 2x4 blocks and nail screw into side of rafter then add your 2x4 stacked on the rafter. I have been past the house in the last year and the same roof is on the house. That s what my framers always did to fur out for insulation.

This allows the panels to be securely attached to the rafters for maximum stability. The 2x4 in the photo represents the rafter then 3 5 of foam then furring strip all held together with 5 screw. Even if you used a 2x6 you want it to extend below the existing lumber so it wouldn t have to go all the way to the roof decking. My roof is a very simple gable with a 5 12 pitch.

If you hire a contractor they can explain all of this to you. Not only did we finish up the floor from last week but we also pounded out the sound deadening furring. Yes the roof furring is being used to create ventilation channels for the tops of the sips. Before you cut your boards you ll need to measure the width of your building and calculate the exact length of each rafter.

Furring strips are required if you plan to place a metal roof on top of existing shingles. Metal roofs depend on thin strips of wood known as furring to allow air to circulate and prevent rot. Instead of 2 foam i m going to purchase 1 5 thick so my strips will match my rafters on the 1 5 side. The sips use 7 16 osb as their skins and 8 polyurethane cores.

On this roof i only walked the ridges but on a metal roof of 6 12 or less a good pair of tennis type shoes on dry metal will allow you to walk without slipping. Spacing of furring strips for metal roof when installing a metal roof over an existing roof insulate the spaces between the wood strips with rigid insulation to prevent condensation before. Furring strips nailed into the rafters through the shingles. Malcolm you mentioned the advantech sheathing and i read up on it and there is a lot of positive reviews.

If the existing rafters aren t all nice and straight you could straighten up the ceiling with some sisters. It is 12 12 so not much snow sticks. The roof rafters provide integral structural support to the roof. They are compatible with many different kinds of synthetic underlayment.

It is supposedly even better than plywood. 00 tj 4 lift 35 s 4 56 s.
