Rooftrain Video One: Laying Out

Independent Slate Supplies has teamed up with Alan Lander of Rooftrain (CITB Trainer, Assessor and IV) for a series of short educational video guides. This series of short educational guides will be available in chronological order and incorporate the planning stage of a roof through to its completion.
With nearly 100 years of experience between them, Steve and Alan have accumulated a vast knowledge of roofing techniques and roofing products, so for those wanting to improve their own understanding, these videos will be worth watching.
The first step is 'Laying Out'.
These videos have been designed to help when slating a roof, but should not be relied upon and you should seek your own independent advice when slating a roof.

[@robertslater5706]

Fantastic. Thank you.

10mm nominal drape - you learn something new every day

[@Reddwarf1994]

Personally I don't put my felt trays on before I fix my first batten. Measuring off a bare fascia board is more accurate. Once the first batten is fixed lift the bottom of the membrane up and then fix the trays.

[@Morning_Rays]

Hi thank you for the wonderful instructional video. I noticed your support tray is lifted up above the facia board. Why is this required and how much lift is required?

[@Mt3Dpdrtk]

What’s this gap against the wall all about then? I pin the felt to the wall with the batten; providing a secure channel for any water ingress (but carefully as to not damage the felt).

[@edwarddevon5499]

I can see that you put the batten up to the line. So thats the first full slate batten. Can you please tell me the distance from the top of that first batten to the eve because i havent got a clue what you are saying

[@don1mark]

Get your length of the slate, take off your headlap (3 inches) and half the measurement that’s your gauge! Example a 24x12 slate 24 - 3 (your headlap) = 21 then half that 10.5 so 10.5 is your gauge always subtract 3 inches from your slate length

To fix the felt NHBC no allowed nails now

[@ianstevens9655]

Wow the i dear is good but needs to explain why you are doing it. Slates are sorted into a grade to get max use out of the slates. Thin at the bottom would where out before the top. Because of the water run of. 😢

[@serbancatalin1875]

It's this NHBC standards?

[@serbancatalin1875]

The lap needs to be tape

[@danielserban9419]

Where's thr over fasci vent?

[@jordy798]

where you get that chalk line?

[@Mt3Dpdrtk]

Eeeeevryone got that chalk line, roofing suppliers

[@don1mark]

That’s a really long way round getting your gauge

[@donaloconnor3352]

Why is there a double batten at the bottom of the roof?

[@carlrhodes3421]

For the eaves course

[@donaloconnor3352]

@@carlrhodes3421 could you explain why two are needed for that?

[@carlrhodes3421]

Slates are laid double lap. i.e. each slate covers the heads(top edges) of the slates on 2 courses below. The eaves course serves as the second head for the second full course of slates to cover to keep water out.

[@markwoods1130]

When did you leave the star ship Enterprise 😂😂😂

[@mintymintygogo]

You haven’t explained how to work out the gauge without explaining how you worked out your head lap or explained what a double lap means - also your first slate overhang is 65mm but everyone else says 50mm. Why have you got this wrong? Also no explanation of where the bottom of the first row of membrane sits- I’m slating a roof for the first time today and it’s hard to find a video with the information I actually need!!

[@mattydeathgoon]

As a roofer. he so old school he doesn't know what he's on about anymore. Gauge stick lol 😅😅 . We call it an idiot stick.

[@user-xf2qt5il7n]

Well, depends who you're working with. Me? I'm only just getting back into roofing after a long time and would like to use he gauge batten; once you've finished them then measure back to the datum.

[@user-ku4un2kk4t]

It would be nice to have the time to make sure you have exactly 10mm drape between every truss using a template. Unfortunately in the real world where time is money and the money isn't on the job you don't get this privilege.
