As a business I used quite a lot of these we normally put a blob of resin on the bottom of each pedestal No harm to the covering Very quick to go down We normally do a 30m2 balcony (roof) in a day 20-25 mil Porcelain Indestructible and you say You can easily remove them for cleaning or unblocking drain Just lift off

We used full fill on our last build Seem to work ok

Unles your over three floors there’s nothing stopping you

Eaves and ridge ventilation

I wouldn’t omit either You need that airflow

You have my sympathy I’ve been on two of these corses Two hours of my life I’ll never get back

Your welcome

We just added two roof lights and didn’t go back to planners To high to bother anyone

We slated our first As real beginners My wife and myself slated our recent build 50 degree roof four valleys like yours and four ten meter valleys The only difference is that I bought an auto cutter from the US Works like tin shears No more marking the slates on the back Leaves perfect riven edge Probably not use it again But 200 quid well spent

They will be fine Use the slate and a halve sparingly Its ok to drill the smaller triangles where ever you can fix

As above all of these should be normal slate

12 mil PB is fine for the whole kitchen

Definitely SE is a must Most will do your BC submission if required A lot cheaper than an Architect
