Roof Area Data

2 estimate the roof drain outlet size you will likely use.

Roof area data.

R value of various materials. You should of course see the manufacturer provided technical data sheet for the r value of specific products. From table 1 one 4 leader at 4 rate of rainfall will take care of 3 460 sq. Equals 32 6 or 33 drains required.

For a 4 hourly rainfall and 4 leader each drain can handle 4 600 sq. Our roof calculator uses base length and base width to find the estimated area. Area is defined as the expanse or measurement of a given surface and there are a few methods for measuring your roof s area. Divided by the 4 600 sq.

Divide total roof area by area found in step 3 to obtain the number of drains required example. The base width is the distance from one corner of your roof to the other at its base on the short side of your house. Roof area is 200 x 500 100 000 sq. Number of roof.

Below to obtain roof area that can be handled by each leader. Total roof area 500 by 200 100 000 sq. 4 roof drain 3 determine your building s location on the above map to determine the approximate rainfall as measured in inches per hour. By experimenting with different aircraft camera systems and applying computer vision we continue to produce the highest resolution imagery available in the market today so we can exceed any customer requirement.

Determine rate of rainfall for this example use 4. There are currently over 50 000 establishments engaged in the installation roofing siding and sheet metal work valued at a total of 31 4 billion. Here s a handy r value table that covers most types of roof coverings building insulation and a few other materials. After studying building plan and physical arrangement assume that 4 leaders are required for this project.
