What’s the Right Roof for You?
Wondering which roof is going to be right for the next project? Roof selection depends on building use, budget, desired appearance, and longevity. For long-term performance, standing seam roofs are ideal. For cost-conscience buyers, exposed fastener roofs are typically the go-to choice. The info below will help make you the most informed buyer on this side of the Mississippi.
1. Design and Construction
Standing Seam Roofs:
Fasteners are hidden beneath the panel or in clips, protecting them from the weather
Raised seams are present (typically 1–3 inches tall) where panels interlock
Exposed Fastener Roofs:
Use visible screws or bolts that penetrate through the metal panel to the structure below
Fasteners with rubber washers are spaced at regular intervals across the panel surface
2. Performance and Durability
Standing Seam Roofs:
Excellent resistance against water intrusion
Floating panels allow for more thermal movement
Longer life expectancy (often 40–70 years with minimal maintenance)
Meet modern energy code requirements
Exposed Fastener Roofs:
More prone to leaks over time as fasteners can back out or washers degrade.
Limited thermal movement flexibility, increasing stress on fasteners.
Moderate life expectancy (20–30 years), often requiring leaking screws to be replaced
3. Installation and Cost
Standing Seam Roofs:
More complex installation requires seaming tools and experienced crews, leading to higher installation costs
For installation directly onto metal building purlins, the minimum thickness is 24ga
More expensive than 26ga exposed fastener counterpart
Very low long-term maintenance and repair costs
Exposed Fastener Roofs:
Simpler and faster installation
Common for DIY or budget-conscious projects
Lower material costs since 26ga panel is often used
Screws will likely have to be replaced with larger screws overtime as holes “oval” or washers fail
4. Aesthetic Appeal
Standing Seam Roofs:
Sleek, modern appearance
Often preferred for commercial, architectural, and high-end residential applications
Exposed Fastener Roofs:
More rugged look with visible screw lines
Commonly used in un-inhabited spaces like agricultural buildings, industrial facilities, and garages/warehouses.
