Fast, quality roof curbs at a great price!

For most applications, we recommend aluminum curbs for their ability to significantly reduce weight and prevent corrosion. However, galvanized steel curbs are a suitable alternative for high-load applications or when working within a tight budget.

We have an extensive catalog of metal building roof profiles, spanning several decades. If you can provide the make and model of your roof panel, we’ll ensure a perfect, weathertight fit. If panel details are unavailable, no worries—we’ll provide a template to gather the essential dimensions for custom fabrication. Either way, we have you covered.

When selecting the appropriate roof curb for your metal building, there are three primary options available, each with distinct benefits and specific considerations:

Seam Clip (Standing Seam) or Layover (High-Rib Screw Down) Curbs offer maximum protection against water leakage. The side flanges extend to the next natural high, eliminating fasteners in the water plane. This curb design is best when there is some flexibility with the install location as the rib cups are welded in place.

Standard Flange Curbs are the most economical alternative. These curbs come with standard 3″ side flanges that are attached in the flat of the roof panel. A unique benefit of the standard flange curbs is the option to include Loose Rib Cups, which allow for lateral adjustments during installation.

Internal Flange Curbs feature a base flange that bends inward, contrasting with the outward bend of most other curbs. This style is often favored by builders erecting Butler and Varco Pruden buildings. The curb design includes all necessary subframe systems. We advise this option for builders familiar with installing this specific curb type.

We’re fully equipped to fabricate curbs to your specified dimensions. Whether you have exact measurements, a mechanical schedule, or need guidance based on our industry expertise, we make ordering customized curbs straightforward.

We can supply square to round adapters called collar tops to handle round pipe penetrations through any metal roof system. These collar tops are a separate accessory making it easy to pass the pipe through a standard square curb and flash the pipe using the collar top component.

Our expertise includes fabricating curbs that ensure a level mounting surface for rooftop equipment, crucial for powered ventilation and HVAC units. For skylights, roof access hatches, and vents, they can mount on a slope to optimize cost-efficiency.

Our aluminum curbs come with a 20-Year Manufacturer’s Material Warranty, highlighting their durability and corrosion resistance. Galvanized steel curbs carry a 1-Year Warranty, reflecting their different protective qualities. This underscores our recommendation for aluminum curbs when feasible.

Lead times vary – small orders (1-3 curbs) ship within 1-2 weeks, medium orders (3-10) in 2-3 weeks, and larger orders (10+) in about 4 weeks. We always take your project timeline into consideration to best align with your construction schedule.

Even with minimal information, we can offer a preliminary quote for your budget planning. As project details become clearer, we aim to keep the final order close to our initial estimate, ensuring financial predictability.

Our 60+ years in the roof accessory business and control over 80% of our product fabrication distinguish us from others. This expertise allows for better control over quality, pricing, and lead times, offering you a comprehensive range of products from a trusted, single source.

Yes, we provide custom color finishes for our curbs to complement the color of metal roofs. Additionally, we offer a standard white paint option for curbs used on built-up applications with cool roofs. For cost-effectiveness, we recommend choosing a powder coat finish. However, for those seeking a premium option, we also offer a Kynar coat, which is available at a higher price.
