LVL Roof Beam Span Tables: A Guide to Choosing the Right Size

When it comes to designing and building a roof structure, one of the most critical components is the LVL (Laminated Veneer Lumber) beam. The size of this beam plays a crucial role in determining the overall strength and stability of the roof. In order to ensure a safe and durable structure, it's essential to choose the right LVL beam span tables.

Understanding LVL Beam Span Tables

Before selecting an LVL beam, it's important to review the rule of thumb calculations and those provided by other methods with a certified professional. This is because the load parameters of the roof can greatly impact the required size of the beam. A wider beam may be more suitable for certain loads, while increasing the beam's width while maintaining the same depth can support greater weight.

Determining LVL Beam Size

When determining the size of an LVL beam, there are several factors to consider. One general guideline is that the depth of the beam should be equal to the span in inches divided by 20. For example, if the span is 16 feet (192 inches), the depth would be 9.6 inches or 9-1/2 inches.

LVL Beam Width and Depth

The width of an LVL beam should also be considered. A good rule of thumb is that the width should be 1/3 or 1/4 of the beam's depth. For a 16-foot span, this would mean choosing a 3-1/2 inch wide by 9-1/2 inch deep LVL beam.

Choosing the Right Beam

Manufacturers often offer span charts based on various construction criteria, such as one or two stories, beam span, carrying span, beam usage, placement, and live, dead, and/or total loads. By considering these factors, you can choose the appropriate LVL beam size for your specific project.

In conclusion, choosing the right LVL roof beam span table is crucial to ensuring a safe and durable structure. By understanding the importance of load parameters, depth and width of the beam, and considering various construction criteria, you can select the perfect LVL beam for your project. Always consult with a certified professional before making a final decision.
