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.
