Rafter spacing for metal roofing how to#

Start by establishing the position for the first roof batten at the eaves (the lowest point on the roof).

Below, we’re going to talk you through a simple and practical method for calculating the correct roof batten spacing for your tiled roof. The distance between roof battens is often referred to as the batten gauge. There’s no question that working out the right roof batten spacing is a critically important step, whether you’re building a pitched roof on a new build, or finishing off a refurbishment project by tiling the roof.

How to Calculate Batten Spacing for Roof Tiles Battened roofs are also easier to maintain and are capable of withstanding harsh winds without faltering. As well as providing a robust anchor point for the nailing of slates and tiles, battens can also help to increase ventilation and weather resistance, reduce ice damming, and even reduce heat loss and gain. Roof battens are lengths of wood that are fixed along the trusses of a roofing structure to form a base on which roof tiles can be hung.

We've had a great time with the chickens. There should not be harsh smells with these methods.Īll hens so no crowing going on. Same sort of principle applies but instead of just drying out the poop the entire run basically becomes one big compost pile. Basically 6' or so of ground up tree matter from a local tree service. We also use diatomaceous earth in the bedding which helps with the drying. We also have a poop tray filled with PDZ stall freshener which acts like a giant kitty litter box under the roosts. There is several inches of pine shavings that quickly dry out the poop. We're using the deep bedding method in the coop.

The key to controlling the smell is controlling the moisture. The entire side will then be covered with 2x4 welded wire. The lower 4' of the sides will be 1/2' hardware cloth with the upper portion covered with poultry netting. We're being very proactive with predator control. We also have rail road ties around the run on the garden side and the other sides will have large sand stone landscape rocks all around the perimeter. The diggers will be deterred when they can't get past the wire and they're not smart enough to back up and try farther away. 24' of welded wire attached to the lower 2圆 on the run and extending out on the ground from the run. The 12' ctrs will make it feel better to work on. If you do get a excess snow then you could pull it off. Looking at the Lafayette info the winds are one to watch. The 2x4 strapping will help the rafters to work together. as that is the longer span strength and would use less wood. If you intend to sister every second then it would be a sure thing if you just used 2x4's ctrs. The coup roof is good for about 20psf but would not spend much time mid span. The rafter length at pitch would be longer but its structural length is the horizontal measurement if that makes sense. The span in the table is for a 3:12 pitch but the span is the horizontal measurement. It really depends on the grade of wood but the most conservative in the table is eastern spruce at 8'-7'. If the walls are 2x4 then the clear span from inside wall to inside wall is 8'-5'. Just for the heck of it the snow loads for Fayetteville AR is also 20 psf. Looking at the span table the shortest span for a live load of 20 lbs/sq ft is 8'-7'. Back to get more 2x4's tomorrow and continue on Monday.Īnd here's how far I got on the run today. Here's some pics of where I stopped today for reference. I cheated and had the fence guys set all the posts for the run while they were here.

Here's the 9' section of privacy fence that will become the west end of the run and the angled gate connecting the storage building so I have access to the implement storage area. It connects with my storage building and parking area behind my shop. I had a fence company do the 8' privacy fence that forms the chicken yard.

Chickens will have no access to the garden. The whole chicken extravaganza borders our raised bed garden. The coop is an extension of my compressor room on the back of my shop. The sides of the run will be covered with 1/2' hardware cloth and then 2x4 welded wire. The run is an outdoor area where the chickens are secure and under roof but can forage and do what chickens do. The coop is separate from the attached run. I'll be laying perpendicular 2x4's flat on 16' centers to screw the corrugated roofing to. I decided that I would sister every other rafter so every other rafter is a double 2x4 on 16' centers.
