Specialized Flat Roof Repair Services
Our comprehensive repair solutions address the most common flat roof issues using advanced materials and proven restoration techniques.

Membrane Puncture and Tear Repair
Flat roof membranes can develop punctures from foot traffic, equipment installation, or debris impact that create immediate leak points. We assess puncture damage to determine if repairs can be made with patches or if membrane sections require replacement.
Our repair process includes cleaning the damaged area, applying appropriate primers, and installing reinforced patches that exceed the strength of surrounding membrane. We ensure all repairs blend seamlessly with existing materials and provide long-term watertight performance.

Seam and Joint Restoration
Membrane seams and joints are common failure points where thermal movement and aging cause separation and water infiltration. We inspect all seam areas using specialized tools to identify current and potential failure points throughout the roofing system.
Our restoration process includes cleaning existing seams, removing failed sealants, and re-welding or re-adhering joints using manufacturer-approved methods. We apply new sealants and protective coatings that restore watertight integrity and prevent future seam failures.

Ponding Water Solutions
Standing water on flat roofs accelerates membrane deterioration and creates leak risks that require immediate attention and permanent drainage solutions. We identify ponding areas using laser levels and moisture detection equipment to map water accumulation patterns across the roof surface.
Our solutions include installing additional drains, creating drainage channels, or adjusting roof slopes to eliminate standing water conditions. We also repair membrane areas damaged by prolonged water exposure and apply protective coatings to prevent future ponding-related deterioration.

Flashing and Penetration Repair
Roof penetrations and flashing details are critical areas where improper sealing or aging materials commonly cause leak development in flat roof systems. We inspect all penetration points including HVAC units, vents, pipes, and equipment mounts to identify current or potential seal failures.
Our repair process includes removing old sealants, installing new flashing materials, and applying multi-layer sealing systems designed for long-term performance. We ensure all penetration repairs maintain proper drainage and thermal movement accommodation while providing superior weather resistance.
Our Flat Roof Inspection and Assessment
Moisture Detection Analysis
We use electronic moisture meters and infrared thermography to locate trapped moisture within roofing assemblies that indicate leak sources. Our moisture analysis helps prioritize repair areas and prevents hidden damage from spreading throughout the roof system.
Membrane Condition Evaluation
We assess membrane surface condition, flexibility, and adhesion quality to identify areas requiring immediate attention or preventive maintenance. Our evaluation determines remaining service life and helps plan cost-effective repair strategies.
Drainage System Assessment
We evaluate drain locations, capacity, and condition to ensure adequate water removal and prevent future ponding issues. Our drainage assessment includes recommendations for improvements that enhance roof performance and longevity.
Emergency Flat Roof Repair Services
When flat roof failures create immediate threats to your property, our emergency services provide rapid response and temporary protection.
Leak Source Identification
We respond quickly to active leaks and use specialized equipment to locate water entry points for immediate temporary repairs. Our rapid identification prevents continued water damage while permanent repairs are planned and materials procured.
Temporary Weather Protection
We install emergency patches, tarps, and temporary drainage systems to prevent continued water intrusion during severe weather. Our temporary solutions provide reliable protection while permanent repairs are coordinated and completed.
Emergency Drainage Solutions
We address emergency ponding situations that threaten immediate roof failure or create safety hazards for building occupants. Our emergency drainage work prevents catastrophic failures and protects interior spaces from water damage.
Rapid Response Coordination
We maintain 24-hour emergency response capabilities and coordinate with building owners to minimize business disruption during urgent repairs. Our rapid response team prioritizes life safety and property protection while planning comprehensive restoration work.
Frequently Asked Questions About Flat Roof Repair
How do I know if my flat roof needs repair or replacement?
Minor issues like small punctures, loose seams, or localized ponding can typically be repaired cost-effectively. If your roof has widespread membrane deterioration, multiple leak points, or structural damage, replacement may be more economical than extensive repairs.
How long do flat roof repairs typically last?
Properly executed flat roof repairs using quality materials can last 10-15 years or more depending on the repair type and roof conditions. Our repairs come with warranties and regular maintenance can extend repair life significantly.
Can you repair flat roofs during rainy weather?
We can perform emergency repairs during light rain but prefer to complete permanent repairs during dry conditions for optimal material adhesion. We provide temporary weather protection to prevent further damage until permanent repairs can be safely completed.
What causes most flat roof problems?
The most common flat roof issues include ponding water from inadequate drainage, membrane punctures from foot traffic or debris, and seam failures from thermal cycling. Regular maintenance and prompt repairs prevent these issues from becoming major problems.
Do you work on all types of flat roofing materials?
Yes, we repair all major flat roofing systems including TPO, EPDM, PVC, modified bitumen, and built-up roofing materials. Our technicians are trained on the specific repair requirements and material compatibility for each membrane type.
