DIY Wooden Carport

The flat or sloping pent style roof was my original thought, but SWMBO has always hankered after a Shepherd's Hut, and so she therefore desired the her carport to have similar roofing. I may well end up doing as you suggest. We'll see. Especially as I can't get any bloody steel deliveries or posthole digger hire at the moment. So I'll have to wait for a couple of days* weeks* months* years*. *Insert suitable duration here, according to HMGs wishes.




(That's my excuse, and don't you lot do anything to tell her otherwise. I'm quite enjoying my peaceful and restful lock-down)
I was wondering how far the curve would go, if the sides would bulge so to speak…..

Ref felt roofing, cheaper to use yet scottish weather has a habit of ripping it off. At least with tin it is only as secure as the nails securing it.

Ref holes in the metal degrading, using rubber grommets while nailing helps immensely. Using a metal spike for accurate nail positions does ensure secure nails. Metal paint in that nice shade of british racing green adds a bit of colour to it…...

almost forgot, L shape horizontal metal panels along the edge help against the wind as do twisted L bracket tie downs...

Having to secure the same roof two winters in a row teaches you to respect winter storms of 80-90mph winds.

Yep. Makes sense. I was planning to use Tek screws (self tappers that also work in wood), which have thick rubber washers already attached. Screw them in (Hex head) and never leaks. Always used for roofing in Kiwiland.

Self-tapping screws don't work for very long in wood. The drill bit is too close in diameter to the screw shank. Galv steel Z-purlins would be better but don't be tempted to self-drill through the roof sheet (drill a clearance hole instead) in case you strip the thread that you'd be cutting in the purlins. It's OK if the roof sheet is thin (or aluminium) and the purlin is thick (or steel) but if they're both the same material of similar thickness, thread-stripping is the likely outcome.

That said, there is a roofing screw that is ridiculously pointy that will puncture galv steel sheet and, not being a self-drill, bites nicely into timber. I can't remember what it's called though. Just don't keep them loose in your pockets.

Good tip thanks:grin:
 
Ehhh . . . Rich, there was a reason I didn't mention Mr Bane's name you know. The bloke seems to attract bad luck disasters.
Yeah like he painted the pallets he used for his wood shed in red to hide the blood spatter....oh how we laughed...
 
The REME know f**k all about construction work...
I guessing your gonna tell us all that the Royal Engineers are better, know all there is to know etc. etc. I’m also guessing that by your user name your probably EOD or ex, but then we all know you're limited to WW2 bombs and an assortment of mines, preferring to leave real EOD work to the RLC. So, fuckwits in glass houses shouldn’t throw stones, as usually you find it’s toughened glass and stone bounces back and hits you right between the eyes.
I could have been RE, but instead I chose a trade.

One point to consider, if installing the carport along the side of the house, make sure you have a means of access for clearing out gutters and blocked pipes

...someone's a bit pre-menstrual....
 
It strikes me that there are two ways to approach this.

Either...

(1) Install really solid fence posts (e.g. 1.5m long150x150x6mm steel angles set 1m deep in concrete with 150x150 timbers coach-bolted to them) and attach a comparatively rickety frame to them...

Or...

(2) Build a substantial, well-braced frame attached to a comparatively light anchoring system (e.g. Metposts set in about 0.5m depth of concrete or, if you are building this on an existing concrete drive, steel angles screwbolted to the concrete).

In (1), you rely on the anchor to provide stiffness to the structure, resistance to uplift and sliding - i.e. bending, axial and shear loads. In (2), the anchor is just to resist uplift (by weight of concrete) and sliding (by shear load) - i.e. just axial and shear loads.
You missed out option 3 and 4...
Option 3. Empty all the fecking shite out of the garage and make room for the car.
Option 4. Get SWMBO to wax and polish the car more often.
No need to thank me.

I don't have a garage, which is why I'm planning on building the carport, and then move on to building a large workshop for moi.
