Major Roof Restoration Project in Scranton, PA

A Scranton Roof in Trouble

When a Scranton property owner reached out to The Flat Roof Guys, they were facing major issues on a mixed-use commercial and residential building. Leaks, sagging, and outdated materials threatened the structure and value of the property. With multiple layers of aging rubber and shingle roofing, along with visible signs of rot and a leaning knee wall, this project required full-scale restoration. As a trusted commercial roofing contractor in Scranton, we stepped in to assess the situation and offer a free estimate. What followed was a complete overhaul, restoring integrity, protection, and long-term performance for the building.

Free Roof Estimate & Site Inspection

We met on-site for a free estimate, inspecting both the lower L-shaped rubber roof and the upper low-slope section of this commercial property. Our experienced team took time to evaluate all problem areas, identifying critical issues like rotting decking, deteriorating rubber material, poor ventilation, and a sagging 35 ft knee wall. Because commercial roofing often involves multiple layers and system types, we carefully examined the transition areas where flat and pitched roofing met. The client appreciated our transparent breakdown of necessary repairs and long-term solutions, especially for such a complex structure. With our findings in hand, we built a customized plan to restore performance and protect the property investment.

Roofing Challenges & Scope of Work

This Scranton commercial roofing project required a tailored solution to handle the complex issues uncovered during inspection. The building had multiple roofing systems layered over time, including rubber, rolled roofing, and shingles. We developed a comprehensive multi-phase plan that addressed the structural integrity of the knee wall, replaced deteriorated materials, and upgraded outdated ventilation. Key elements included complete removal of the old roofing, new ISO board installation, RUSS strip detailing for the EPDM membrane, and full shingle system replacement. We also accounted for commercial code compliance and future maintenance with a 10-year warranty. The scope was significant, but necessary to ensure long-term durability for this high-use property.

Phase 1: Tear-Off & Prep Work

We began by:

• Removing the failing rubber membrane, vents, and old shingles.
• Stripping the V-slope and rear wall areas to inspect the decking.
• Replacing damaged sheathing and preparing the surface with ISO board and RUSS strips for high-performance EPDM application.

Phase 2: EPDM Rubber Roof Installation

We installed a fully adhered 060 EPDM system, using:

• • Spray bonding adhesive for a secure, uniform seal.
  • Inside/outside corner flashings, seam tape, and primer for watertight edges.
  • Reinforced membrane overlaps and detailing to prevent ballooning or future lift.

Phase 3: Shingle Roof Replacement

We upgraded the main roof system with:

• Full shingle tear-off, followed by new Owens Corning shingles.
• Drip edge, synthetic underlayment, ridge vent, and ice/water barrier installed to code.
• New pipe boots, flashings, vents, and trim to ensure full protection.

Phase 4: Structural & Fascia Repairs

To fix deeper structural issues:

• We rebuilt a 35 ft leaning knee wall to correct sag and twist.
• Repaired rotted soffit and fascia below the flat upper roof.
• Used 75 sheets of OSB sheathing, with any unused sheets refunded to the customer.

Results – A Safe, Sealed & Structurally Sound Roof

The final results of this Scranton commercial roofing project were impressive and impactful. After our work was completed, the building had a brand-new EPDM rubber system fully adhered to industry standards, a reinforced structure with a rebuilt 35-foot knee wall, and a visually appealing new shingle roof with modern ventilation components. These upgrades not only resolved the original problems of leaks and sag but also significantly boosted the building’s long-term value and energy efficiency. The property owner was thrilled with our professionalism, attention to detail, and commitment to staying on budget. The job stood as a great example of how commercial roofing projects can be done thoroughly, safely, and successfully — and it earned us yet another 5-star review from a Scranton client.
