Ridge height calculation, allowance for tiling ridge above the truss.

[epsilonGreedy]

I am doing some room ceiling height fine tuning with my brickie team as the walls go up and can calculate wall-plate height very accurately. Above that the quote for the trusses gives the wall plate to peak height to the nearest mm. What I cannot judge is the thickness of the roof ridge tiling above the truss peak.

 

Is there an industry standard or this?

 

It will be a slate roof probably done in Nu-lok.

You need to draw it out to scale so you know +/- a few mm or just go HERE, download the DWG file and measure off that.

We had a problem with this as there was a height restriction to our build. As we had no gable walls it would be difficult to prove actual height but we did reduce the roof slope by a couple of degrees as the original bedroom ceilings proved a bit low. In practice (if I remember correctly) the height from top of truss to top of ridge tile was approx 100mm. But even if they got pedantic I believe you have a margin to the actual figure. As we used “angled” ridges rather than half round they fit more snuggly to the roof (and look better with slate IMO).

 

I think it was @AnonymousBosch that used Nu-lock.
