How often should TPO roofs be inspected?

We recommend twice-yearly inspections: spring and fall. Additional inspections after severe weather, hail, or storms are also advisable. Regular inspections help catch issues early and preserve manufacturer warranties.

What does TPO maintenance cost?

Maintenance costs vary based on roof size and condition. We provide detailed quotes for both recurring maintenance plans and specific repairs. Most property owners find that preventive maintenance saves money by avoiding expensive emergency repairs.

Can TPO seams be re-welded if they fail?

Yes, heat-welded seams can be re-welded if they separate or lift. Re-welding restores seam strength and is much more cost-effective than emergency repairs after a leak develops.

Does maintenance preserve the manufacturer warranty?

Most TPO manufacturers require documented regular maintenance as a warranty condition. SPG’s maintenance program provides the documentation needed to preserve your warranty coverage.

What’s the difference between coating reapplication and cleaning?

Cleaning removes dirt and debris from the membrane surface. Coating reapplication adds a protective layer that restores UV reflectivity, improves appearance, and extends membrane life.

How long does TPO last with proper maintenance?

Well-maintained TPO roofs often last 25-30+ years. Proper maintenance, regular inspections, and timely repairs directly impact lifespan. SPG’s maintenance programs help maximize your roof’s service life.

TPO-Specific Maintenance Needs

TPO roofing membranes, while durable and cost-effective, require specific maintenance protocols to perform optimally. Unlike some roofing materials, TPO seams are heat-welded and can experience stress from building movement, temperature cycling, and UV exposure. Our maintenance program focuses on these critical areas, identifying potential issues through systematic inspections and proactive repairs.

TPO membranes can also attract dirt and algae growth in humid climates, which can reduce reflectivity and contribute to membrane degradation. Regular cleaning and inspection help maintain the membrane’s appearance and protective properties. SPG Roofing understands the unique characteristics of TPO systems and tailors maintenance approaches accordingly.

Heat-Welded Seam Inspection & Maintenance

Heat-welded seams are the critical connection points in TPO systems, and their integrity directly impacts roof performance and waterproofing. Our certified technicians visually inspect every accessible seam, looking for signs of separation, lifting, or stress. We use infrared thermography to identify potential weak spots that may not be visible to the naked eye, catching problems early before they develop into leaks.

When we identify compromised seams, we perform re-welding or repair to restore seam strength. Regular seam maintenance prevents costly emergency repairs and helps preserve your roof’s warranty, as most manufacturers require regular inspections as a warranty condition.

Membrane Cleaning & Protective Treatments

TPO membranes can accumulate dirt, debris, algae, and organic growth that affects appearance and potentially promotes degradation. Our membrane cleaning service removes these contaminants while protecting the TPO surface. After cleaning, we can apply protective coatings that restore UV reflectivity and provide additional protection against weathering and environmental exposure.

Coating reapplication is particularly important for older TPO roofs losing reflectivity. Restoring surface reflectivity reduces heat absorption, improving energy efficiency and extending membrane life. We use TPO-compatible products that bond securely and provide lasting protection.

Drainage System & Penetration Maintenance

Proper drainage is critical for TPO roof performance. We ensure all drains, gutters, and scuppers are clear of debris, allowing water to drain efficiently. Blocked drainage causes ponding, which accelerates membrane deterioration and can lead to leaks. We also inspect all roof penetrations—HVAC units, vents, skylights, and equipment—ensuring that flanges are sealed and not causing leaks or water pooling.

Seasonal maintenance is essential in Indianapolis’s climate. Fall cleanup removes leaves and debris that can clog drains before winter weather arrives. Spring inspection identifies any winter damage and prepares the roof for summer heat and potential storm activity.

What Our Customers Say

Patricia JohnsonIndianapolis, IN

SPG’s maintenance program has kept our TPO roof in excellent condition for over four years. Their twice-yearly inspections catch small problems before they become expensive. The documentation they provide is thorough and helps with warranty management.

Richard OrtizWestfield, IN

We switched to SPG for TPO maintenance after experiencing issues with our previous contractor. SPG’s attention to seam inspection and their knowledge of TPO-specific concerns has been excellent. We now have complete confidence in our roof.

Susan PalmerNoblesville, IN

The coating reapplication work SPG performed on our TPO roof made a visible difference in its appearance and reflectivity. Our facility is noticeably cooler, and they say our energy costs are down. Highly recommend their maintenance services.
