FAQs - Commercial & Non‑Extreme Industrial Buildings
The MR Multi‑Ply® Roofing System is designed for any pitched metal roof experiencing age‑related wear, leaks, or system fatigue - whether the environment is extreme or standard.
Building Types We Serve
No. While the system performs exceptionally well in high-heat and corrosive environments, it is equally effective on standard commercial buildings such as warehouses, distribution centers, retail support facilities, and manufacturing buildings with aging metal roofs.
No. Thermal Tec works across a spectrum of building types, with a significant portion of projects involving standard commercial metal roofs needing lifecycle extension.
The system is commonly used on:
- Warehouses and logistics facilities
- Distribution centers
- Agricultural storage buildings
- Manufacturing facilities
- Commercial support structures
- Pre-engineered metal buildings
- Steel manufacturing facilities
- Aluminum manufacturing facilities
- Brick manufacturing facilities
- Glass manufacturing facilities
It is designed for any aging pitched metal roof experiencing wear, leaks, or system fatigue.
Yes. Warehouses are one of the most common applications due to their large metal roof spans, exposure to thermal cycling, and long-term fastener and seam fatigue.
The most common applications are standard commercial and industrial metal buildings experiencing age-related roof degradation, not necessarily extreme process environments.
No. While Thermal Tec serves heavy industry, a large portion of work involves general commercial and pre-engineered metal buildings.
No. The system scales from smaller commercial buildings to large multi-structure facilities.
Absolutely. The system is widely used on storage facilities, agricultural buildings, retail support structures, and commercial properties without manufacturing processes.
Eligibility & When to Restore Your Roof
No. Roof age, thermal movement, seam fatigue, and fastener deterioration - not environmental severity - are the primary drivers for restoration eligibility.
Yes. Many building owners use it proactively to extend roof life before major leaks occur or before full replacement becomes necessary.
No. It is frequently applied to roofs that are still operational but showing early signs of aging, such as minor leaks, seam wear, rust, or fastener fatigue.
It reinforces the existing roof system, restoring performance without requiring full tear-off, which helps extend usable roof life and delay capital replacement cycles. This allows for 100% tax deduction in the year it was installed.
Because they typically have:
- Large metal roof surfaces
- Minimal slope (increased water exposure risk)
- Long service life expectations
- Cost sensitivity around downtime and replacement
- Keeps rental clients from slow monthly payments due to leaks
No. Even low-disruption facilities benefit because roof deterioration is time-based, not usage-based.
Why It Works on Standard Commercial Roofs
Because most metal roof failures are caused by:
- Expansion and contraction over time
- Fastener back-out
- Sealant breakdown
- Seam fatigue
- Aging materials
These conditions occur in all metal buildings, not just harsh environments.
No. The MR Multi-Ply® system is engineered to reinforce aging metal roof structures regardless of environmental intensity.
No. Those conditions can accelerate wear, but the system is designed primarily around mechanical aging of metal roof systems, which occurs in all environments.
The most common cause is system fatigue over time, including:
- Movement from thermal expansion
- Fastener loosening
- Sealant and seam breakdown
- Aging panel connections
No. It is specifically designed as a cost-effective restoration alternative to full replacement, especially for roofs that are aging but still structurally sound.
The MR Multi-Ply® Roofing System is for any building with a pitched metal roof experiencing age-related wear, leaks, or system fatigue - regardless of whether the environment is extreme or standard.

ABOUT - Transite (asbestos-cement) roofs
Transite roofing consists of Portland cement mixed with asbestos fibers, widely used from the 1920s to 1980s for its durability, fire resistance, and insulating qualities. Many buildings still contain transite asbestos roofing panels that require careful inspection before any maintenance or restoration work is performed. Thermal-Tec specializes in addressing Transite roofs by installing the MR Multi-Ply® Roof System over intact panels, providing a safe, durable solution that seals and reinforces the roof without disturbing hazardous asbestos fibers.
For a deeper explanation of how these panels were manufactured and how to recognize them on older buildings, read our transite asbestos roofing identification guide.
Yes, traditional Transite panels contain asbestos, often between 20% to 50% by weight. ACRM above 1% is considered dangerous.
You can learn more about the material composition and history of these roofing panels in our guide explaining how transite asbestos panels were manufactured.
Any ACRM product containing asbestos is dangerous, however, not when intact and undisturbed. However, if cut, broken, or deteriorated, asbestos fibers can become airborne and pose serious health risks.
As these roofs deteriorate, the cement matrix can break down and expose asbestos fibers. Our article explains the hazards of aging transite asbestos roofing in greater detail.
Transite roofing can be repaired, but only by certified professionals due to the risk of releasing hazardous asbestos fibers if disturbed. Thermal-Tec offers expert repair services, using safe methods to stabilize and maintain Transite roofs, or can apply the MR Multi-Ply® Roof System to reinforce and protect the existing structure without disturbing the asbestos. If you suspect ACRM consult a professional before proceeding. *Learn more at our - Transite Roofing Solutions page
Only if it's damaged or deteriorating. If in good condition, it can be left in place or encapsulated. Removal must be handled by licensed asbestos abatement contractors.*Learn more at our - Transite Roofing Solutions page
Only certified asbestos abatement professionals. Improper removal is dangerous and can result in exposure, legal penalties, and even death.
Yes. Existing Transite roofing is legal, but disturbing it without following proper regulations is dangerous and can cause death or serious long-term health complications.
Painting or coating transite can be done however because the concrete / asbestos matrix will be defeated with the bond being unsuccessful due to the moisture in the concrete/asbestos matrix. *Learn more at our - Transite Roofing Solutions page.
Transite roofs can remain successful 40-70 years indefinitely if properly maintained. Exposure to weather or impact damage reduces lifespan.
ost of these roofing systems were originally designed to last several decades, but many are now far beyond that window. Our article explains the typical lifespan of transite asbestos roofing systems and what happens as they age.
Yes. ACRM is considered by the insurance industry as a pollutant. Special insurance policies classified as insured pollutant type policy may be available but not always.
Yes. Some insurers charge higher premiums or exclude coverage related to asbestos-containing materials. Check with your provider.
There are several roof systems that are not capable of managing the moisture content trapped in the asbestos / concrete matrix. The Thermal-Tec MR Multi-Ply Roofing System can be installed over intact panels without disturbing them. We’ve completed several Transite Projects with long term success. *Learn More at our - Transite Roofing Solutions page.
Always use a roofing professional with a minimum of 10-15 years of experience evaluating and retrofitting ACRM.
If you're unsure what to look for during a visual inspection, our guide explains how to identify a transite asbestos roof using several key characteristics.
Do not proceed with any activity that would disturb the damaged product.
The MR Multi-Ply® Roof System’s warranty covers leaks in transite or asbestos roofs for 10 years post-installation, with the re-warranty program extending protection up to 20 years. Contact Thermal-Tec for detailed terms.
Yes, the MR Multi-Ply® Roof System seals and strengthens aging transite or asbestos roofs, adding flexibility to stop leaks without requiring a full roof replacement.*Learn More with our - Transite Service Install Video
