As I said they do provide a very professional service, I had taken a plan of my roof down to their office which they measured up, being a hipped roof they supplied me with a numbered plan of which sheet goes where and supplied the sheets of varying sizes to fit, the longest of them being 7.2mtrs also at this same time they gave me a price and I think I had to pay around half to commit to the order, if I do remember correctly the sheets, ridge caps, hip caps, all tech screws plus sealant were all included in the price, this was around P130K this was for a roof coverage of 200M2 but at a pitch of 45 Degrees this does cost more than the standard 30pitch, I did not inquire about any fitting service from them but I guess they must do this? With hindsight I wish I had them fit it all, my own workers had an extended time working with this so likely it cost me quite a bit in labour charges and saved me nothing added to that there would be No Warranty with a DIY job.
The time I had to spend in their office was of quite short duration these Guys knew their job well (a very rare quality there in PH) The 130K price included the packing and shipping cost from factory to my door the price for this alone was around 20K, at the time I did think this to be a hefty charge, however it was packed well and there was not even a hint of damage.
I think I went for a thickness of 1.5mm this can be had in 2, 2.5 and 3mm, at 1.5mm I could jump on this sheet and I am a Fat Bar Steward of 100kg, it is near impossible to bend or distort, it really is a very robust material and great to work with.
Send me a PM if you want to look at my roof and there you will see a simple ridge vent, there is bits of scrap there if you want a sample? much of the angled cuts where there is a lot of wastage in a hipped roof, perhaps as much as 10 to 15%? were all used up.
