Gaco Certified Flat Roof Installation for Pittsburgh Commercial and Residential Properties
Flat and low-slope roofing requires a fundamentally different skill set than pitched shingle work — and Blockbuster Roofing LLC has invested in earning the Gaco Coatings certification that demonstrates exactly that expertise. We install flat roof systems for commercial properties and residential applications throughout Pittsburgh, PA, with owner Jonathan Levy directly involved in every project from assessment through final inspection. Whether it’s a commercial building requiring a Gaco silicone system or a residential addition with a low-slope roofline, we install flat roofing correctly — the first time.
What Is Flat Roof Installation?
Flat roof installation is the construction of a low-slope roofing system designed to manage water drainage through controlled slope, proper drainage design, and a fully waterproof membrane or coating. Unlike pitched roofs that shed water by gravity alone, flat roofs require precision at every phase — drainage must be engineered, seams must be perfect, and every penetration must be detailed correctly. A flat roof installed without that precision will fail quickly in Pittsburgh’s wet, freeze-thaw climate. Installed correctly, it delivers years of reliable, low-maintenance protection.
Who We Serve
Flat roof installation at Blockbuster Roofing is primarily commercial work — retail buildings, office facilities, warehouses, and similar structures where flat roofing is standard. We also install flat roofing systems on residential applications where portions of a home use low-slope construction, including garage roofs, home additions, porch roofs, and similar structures where the roofline requires a flat system rather than a pitched shingle approach.
Flat Roof Systems We Install
- Gaco Silicone Roof Coatings — Our primary flat roof solution and the application our Gaco certification specifically covers. A liquid-applied, fully seamless waterproofing system that eliminates the seams where traditional flat roofs most commonly fail. Resistant to ponding water — a critical advantage for Pittsburgh’s flat rooflines that see heavy rainfall and snowmelt accumulation. Available for both commercial buildings and residential flat roof sections
- TPO (Thermoplastic Polyolefin) — A heat-welded single-ply membrane offering excellent UV resistance and energy efficiency for commercial flat roofing
- EPDM (Ethylene Propylene Diene Monomer) — A durable rubber membrane system well-suited for commercial buildings and larger residential applications requiring a proven long-life flat roofing solution
- Modified Bitumen — A multi-ply system offering excellent durability for flat and low-slope applications on both commercial and residential structures
Our Flat Roof Installation Process
- Structural and Drainage Assessment — We evaluate the building structure, existing drainage, and slope to determine the right flat roofing system for your specific application — commercial or residential
- Deck Preparation — The existing roof deck is inspected, cleaned, and repaired as needed. A properly prepared deck is non-negotiable for membrane adhesion and long-term performance
- Insulation Installation — Rigid insulation board installed where required for energy code compliance and to provide the proper surface for membrane adhesion
- System Application — Gaco silicone coatings are applied as a seamless liquid system to manufacturer specifications. TPO and EPDM membranes are properly adhered and seam-welded or sealed to eliminate water entry points
- Penetration and Edge Detailing — Every roof penetration — HVAC units, vents, drains, pipe boots — and every perimeter edge receives meticulous detail work. These are the points where flat roofs fail most often, and we treat them accordingly
- Drainage Verification — We verify all drains, scuppers, and gutters are functioning correctly and the roof surface drains within the 48-hour standard before we sign off
- Owner Final Inspection — Jonathan Levy walks every flat roof installation at completion. We do not leave until the system is verified correct throughout

- Seamless Waterproofing — Gaco silicone systems cure into a fully seamless membrane, eliminating the joints and laps where traditional flat roofs most commonly fail

Frequently Asked Questions
What is the advantage of Gaco silicone over traditional flat roof membranes?
Traditional flat roof membranes like TPO and EPDM are installed in sheets with seams that must be welded or sealed. Those seams are where water finds its way in over time. Gaco silicone is applied as a liquid that cures into one continuous, seamless membrane — eliminating the seam problem entirely. For Pittsburgh’s wet climate with frequent ponding water conditions, the seamless system is a significant advantage.
Does Blockbuster Roofing install flat roofs on residential homes?
Yes, for residential applications where portions of a home use low-slope construction — garage roofs, additions, porch roofs, and similar structures. Our primary flat roofing work is commercial, but we bring the same Gaco certified expertise to residential flat roof applications throughout the South Hills.
Can Pittsburgh's winters handle a flat roof?
Yes — when the system is designed and installed correctly. Proper drainage, correct slope, quality insulation, and the right membrane for the climate are all critical. Gaco silicone specifically is rated for performance in freeze-thaw conditions and maintains flexibility in cold temperatures. We assess every application and recommend the right system for your specific situation.
What warranty does my flat roof installation include?
Every flat roof installation from Blockbuster Roofing is backed by our 15-year workmanship warranty plus applicable Gaco Coatings or membrane manufacturer warranties depending on the system installed. We review all warranty coverage before construction begins.
