When a commercial roof reaches the end of its service life or suffers severe damage, repairs may no longer provide a lasting solution. In these cases, a full roof replacement offers the most dependable way to restore protection, improve energy efficiency, and ensure long-term performance. At Hi-Line Commercial Roofing, we specialize in replacing worn-out or failing roofs with advanced single-ply roofing systems designed for strength, flexibility, and cost-effectiveness.
When Replacement Is the Right Choice
Over time, constant exposure to UV rays, ponding water, and extreme temperature changes can cause significant deterioration. Telltale signs that your building may need a complete replacement include:
- Large areas of blistering, splitting, or seam failure
- Persistent leaks despite repeated repairs
- Wet or saturated insulation
- Structural damage from storms or heavy snow loads
- Rising energy costs due to poor insulation or reflectivity
When these issues appear, patching or coating may only delay the inevitable. A full replacement ensures a clean slate, eliminating underlying damage and preventing future problems.
Why Choose Single-Ply Roofing?
For most commercial roof replacements across North Dakota and Montana, single-ply roofing has become the system of choice. These membranes, typically TPO, PVC, or EPDM, are lightweight yet durable, offering long-term waterproofing and energy-saving benefits. Unlike traditional multi-layered roofs, single-ply systems require less material and labor, resulting in a faster and more cost-efficient installation.
Key advantages include:
- Superior durability: Resists punctures, chemicals, and UV radiation
- Energy efficiency: White reflective membranes help reduce cooling costs
- Ease of maintenance: Fewer seams and simplified inspection
- Longevity: Expected lifespan of 20–30 years with proper care
Compatible Substrates for Single-Ply Replacement
Single-ply systems can be installed over a wide variety of roof decks and existing materials, making them ideal for full replacements on nearly any commercial structure. Common compatible substrates include:
- Metal roofs: After proper preparation, single-ply membranes can cover aging metal panels, sealing fasteners and eliminating leaks
- BUR (Built-Up Roofing): When a built-up system becomes brittle or cracked, a new single-ply layer offers improved flexibility and waterproofing
- Modified bitumen: Replacing this material with TPO or PVC enhances reflectivity and heat resistance
- EPDM or PVC: Older membranes can be removed and replaced with new single-ply systems for upgraded energy performance
- Concrete decks: Ideal for large commercial facilities, single-ply membranes form a watertight barrier over rigid surfaces
No matter the substrate, proper surface preparation and insulation are essential. Hi-Line Commercial Roofing ensures every layer, from deck repair to membrane welding, is completed to the highest standard.
Expert Replacement from Start to Finish
Our experienced crew follows a detailed process to ensure quality and safety at every step. We begin with a comprehensive roof inspection and moisture analysis to determine the extent of damage. Next, we remove the failing materials, make any necessary structural repairs, and install a high-performance insulation board before laying down the new single-ply membrane. Heat-welded seams create a monolithic finish that provides exceptional leak protection and long-term reliability.
