1. Is the Roof Wind Designer web application free to use?

Yes, the Roof Wind Designer web application is free to use. This web application was developed to provide users with an easy-to-use means for determining roof systems' design wind loads. To use the web application you are required to register for a free account.

2. How do I make changes to an existing project?

Once a project is saved no changes are allowed to be made.

3. How do I delete my old projects?

For legal reasons the web application currently does not allow projects to be deleted. You can mark a project as "Inactive" to hide the project from showing up by default on the "My Projects" web page.

4. On the "Project Information" screen, I was able to select a Project State, but the Project County is shaded and reads "Not Applicable." Why?

Roof Wind Designer determines basic wind speed values by county. If all of the counties in a state have the same basic wind speed value, the Project County pull-down menu does not invoke.

5. I entered in a zip code that I know has a basic wind speed of 140 mph, but Roof Wind Designer gave me a value of 150 mph?

Roof Wind Designer determines basic wind speed values by county. If two or more wind speeds occur in a particular county, the highest wind speed will be used. If do not want to use the default value, you can change it on the Basic Wind Speed page.

6. I registered for a new account but have not received an e-mail confirmation to activate my account. What should I do?

NRCA recommends you check your e-mail spam filters to make sure the Roof Wind Designer e-mail confirmation is not being blocked. This is a common problem with account registrations.
