Your updated site is brilliant …. and I hope those who use it will subscribe.
Michael (M J Corbett & Associates Pty Ltd)
quite impressed with your work, I just had an
inquiry from my architect to modify the gutter design which would
involve a recalc of the how many down pipes would be needed, your
little program did this within seconds, THANKS !!
Chris (Weiss builders)
I have been using it for a number of years but hadn’t subscribed,
I have found the features available since subscribing are very helpful,
and feel guilty that I hadn’t payed in the past.

Great work as always Ken. No roof gutter design shall leave this office without the calculations and justification for sizings.
Jahan Trevena, Principal of McLauchlan & Associates Building Design Consultants.
I’ve tested this with an example (by hand, using 3500.3 charts) and agree with your results

Love your program, I use it all the time these days since everything residential is more heavily scrutinised.

What a fantastic website for owner builders! Thank you -
took me less than one hour to meet the requirements of my building
certifier... Thank you!

It is all good. I have done my first calculation.
PDF is printed.
Wow – it takes the worry out of it.
Thanks for a wonderful product.
Martin (Design Delight).
Over the years I have asked Ken a few times for some advice in areas, when I was a little unsure myself.
Like how much efficiency is lost on an eaves gutter when the downpipe is connected to rear of the gutter and not the base
(typically seen in many WA project homes) He has always astounded me with his thorough responses obviously spending many hours
undertaking complex mathematical calculations. He is one of the true gentleman in this industry always prepared to help others.
I will continue to purchase his software and highly recommend it to others.
It saves me many hours of tedious work on each project no matter how I choose to use it.
Keep up the good work Ken, I enjoy reading your posts our industry needs more people like you.

Thanks for a great site and a very useful tool.
I assist the QBCC with plumbing and roofing issues and find your site to be a great assistance in quickly determining downpipes and gutter sizes.
