Span calculations help you determine not what the load on the structure is - but what it could be. And that is very important here in CT, because we never quite know what our snow load will be.
The PSF (pounds per square foot) snow load is an important factor to take in. A roof may look fine and be perfectly functional for months, or even years, before there is enough snow to cause an issue.
In reality, span calculations are very easy. To make them, simply use an online calculator like this one. Have questions? Contact us!
