I'm shopping for snow blocks for my 10/12 metal roof. Any idea how to calculate the number of blocks to use for a given linear distance? Thanks!!	Guest User 10/25/2007	Share Or copy this URL: https://www.metalroofing.com/spirit/comment/10432/find/
Also it seems most snow blocks on the market are clear plastic. Are they UV proof or would it be better to get colored plastic?	Guest User 10/25/2007	Share Or copy this URL: https://www.metalroofing.com/spirit/comment/10433/find/
The polycarbonate snowguards are all UV resistant. I often suggest one guard every 18", staggered over two rows. However, so much depends upon your roof design and anticipated snowload. Your roofing manufacturer or your snowguard supplier should be able to help.

Ptich and eave width are necessary, but the most important dimension needed to determine the snow guard pattern is run from eave to ridge. This will dictate how far up the roof snow guards need to be placed. On longer runs a second grouping of snow guards may be needed to break the snow's momentum. Over thirty companes manufacture snow guards in a multitude of materials-including Galvainized and Stainless Steel, TCS, Copper, Lead Coat Copper, Cast Aluminum, Cast Bronze and of course plastic. Most plastic products are made with UV protection. Most are clear, but some are cloudy. You will be able to see the color of roof through the clear ones. However, if you go with a painted product be sure to get one that is matched to your roof's color, and not just a "standard" green.

Roof material, snow load for the geographic area and pitch of the roof should be considered also. If someone wants a sample estimate, see my web site and select "Estimating". You can print the "pdf" form and fax it with requested info. (Submitting some "*.jpg" photos are helpful.) I installed snow guards for 31 years and continued the Cody Snow Guard 6 years ago as the Gough SnoGuard. www.SnoGuard.com Any questions can be forwarded to [email protected]	Guest User 11/29/2007	Share Or copy this URL: https://www.metalroofing.com/spirit/comment/10436/find/
Thanks for weighing in.	Todd Miller Isaiah Industries, Inc. 12/1/2007	Share Or copy this URL: https://www.metalroofing.com/spirit/comment/10437/find/
Wouldn’t the pitch of this run be important as well? Say I have a run of 18” but it’s on a 12/12 and about fifty feet wide, would I need two rows or just the one?

With only 18" runs, I would think you would be fine with only one run.	Nate Libbey 1/8/2009	Share Or copy this URL: https://www.metalroofing.com/spirit/comment/10439/find/
