FAQ - Buildings: roofs

What is the weight of the roof structures?
The roof structure consists of the rafters, purlins, brace angles, sheeting, and fasteners. The weight can vary greatly depending on the loading requirements. Most customers asking this question are concerned about unloading the material from the delivery truck. We limit our load bundles to a maximum of 3000 pounds. Most bundles are 1200 to 1700 pounds. After you purchase a building and check on availability of a forklift and/or crane, if you need a specific weight limit on the bundles, in most cases we can accommodate you.

Do your gable ends and/or eave of the roof come with a closure to keep out varmints?
Yes. Our roof systems include trim material, mastic tape, and closure strips that, when properly installed, not only create a barrier against birds and other varmints but provide an effective weather seal. Obviously, every stage of construction is important, but it is especially important that erectors take their time and install this system correctly. It will be the difference between a leaky building that is prone to rust and mildew and a weather-tight structure that will stay snug, warm, and beautiful for decades. We have produced an outstanding instuctional video which covers this procedure and much more. You can order the VHS tape with one of our project planning packages, or broadband users can view a streaming video of this segment.

How long does it take for moisture to damage sheets that haven't been installed?
Most problems occur when sheets are left bundled for several weeks, but there is no reason to take chances. When we send drawings, we include instructions on how to care for bundled sheets, and it is important to read and follow those procedures.

Do you sell standing-seam roofs?
At present, we can provide standing seam via special quote.

Can I order an overhang on the roof?
Yes you can. See the section on roof extensions for full details.

Can air conditioners be mounted on your roofs?
We can provide point loads on the roof if you can tell us the weight and other pertinent information about the air conditioners. To do this, you will need to request a special quote.
