Commercial & Industrial Roof Repair

Reliable Roofing Solutions for Businesses

Leak Stoppers Inc has built a reputation as Long Island’s most reliable roof consultant, specializing in commercial and industrial roofing and waterproofing. From same-day emergency service calls to comprehensive roof surveys, our team, led by founder John O’Connell, provides unmatched expertise backed by decades of experience.

Comprehensive Roof Diagnostics

Our evaluations include:

• Initial membrane assessments
• Roof installation workmanship reviews
• Roof traffic analyses
• HVAC unit and wall system inspections
• Drainage design reviews

When necessary, we employ core sampling and nighttime thermal imaging to detect hidden moisture or questionable decking. This ensures accurate leak detection and cost-effective solutions.

Advanced Leak Repair & Waterproofing

Modern commercial roofs face challenges from traffic, debris, wind forces, and structural stress. Leak Stoppers Inc provides:

• Leak detection and repair using advanced diagnostics
• Negative air analysis to identify vacuum-related leaks
• Flashing, weather stripping, and sealant repairs
• HVAC, skylight, and solar array maintenance
• Drainage and coping system repairs

Our technicians are trained in HVAC, plumbing, roofing, and siding systems, ensuring leaks are addressed at their true source.

Roof Engineering & Replacement

When replacement is necessary, we redesign systems with:

• Optimal R-values for insulation efficiency
• Expansion joints and counter flashing
• Improved wall systems and fasteners
• Enhanced drainage solutions

We install complete roof systems with warranties ranging from 15 to 30+ years, using TPO, EPDM, Modified Bitumen, and silicone coatings.

Cutting-Edge Technology

Leak Stoppers Inc leverages:

• Thermal imaging to detect hidden moisture
• Moisture meters for precise diagnostics
• Drone inspections for safe, accurate measurements
• Proprietary data combined with AI analysis for fair pricing and reliable results

This blend of science, technology, and experience makes us one of Long Island’s premier commercial roof consultants.

Roof Coating Solutions

For low-slope (flat) roofs with multiple layers, full replacement can cost $9–20+ per sq. ft. In very unique cases, Leak Stoppers may offer a cost-effective temporary alternative:

• Roof coatings applied at a reduced cost
• Manufacturer warranties up to 20 years
• Extended roof life without disruptive tear-offs

Please note: Roof coatings are very rarely suggested due to their nature as a temporary solution, often coming without manufacturer guarantees. Leak Stoppers Inc does not recommend roof coatings and will only consider their use as a temporary solution until a proper roofing system can be installed.
