Metal Roof Repair in Janesville, WI

Metal roofing systems are renowned for their exceptional durability, energy efficiency, and longevity, often lasting 40-70 years with proper maintenance. However, even the highest-quality metal roofs can develop issues over time due to Wisconsin's harsh weather conditions, including severe storms, hail damage, temperature fluctuations, and heavy snow loads. When problems arise, prompt professional attention is crucial to prevent minor issues from escalating into major structural damage.


Metal roof repair requires specialized knowledge of different metal roofing systems, proper fastening techniques, and compatible materials that maintain the roof's integrity and performance. Unlike traditional roofing materials, metal systems expand and contract significantly with temperature changes, creating unique challenges that demand experienced professionals who understand thermal movement, proper sealing methods, and manufacturer specifications. 


Janesville Superior Roofing brings extensive experience working with all types of metal roofing systems, from standing seam and corrugated panels to architectural metal shingles and commercial membrane systems. Our skilled team quickly identifies the root cause of problems, whether they involve loose fasteners, damaged seams, corrosion issues, or storm damage. We use manufacturer-approved materials and proven repair techniques that restore your roof's protective capabilities while maintaining its appearance.

We deliver thorough repairs that address all aspects of metal roofing integrity. Our team focuses on identifying damage accurately, stopping leaks efficiently, and restoring roofing after severe weather events.

Damage Assessment

We start every job with a detailed inspection to evaluate your metal roof’s condition. This includes examining seams, fasteners, panels, and flashings for rust, corrosion, or physical damage.



Using both visual and moisture detection tools, we pinpoint weak spots and areas prone to future issues. Our thorough assessment guides the repair process, ensuring no damage is overlooked.

Leak Detection and Prevention

Leaks in metal roofs can stem from damaged panels, faulty fasteners, or deteriorated sealants. We use advanced methods to locate even small, hidden leaks that could cause significant water damage over time.



Once detected, we seal leaks with high-quality materials designed to withstand weather exposure and temperature changes. Preventive measures such as tightening loose screws and replacing worn gaskets are standard parts of our service.

Storms can cause dents, punctures, and loosening of roofing components, compromising the roof’s effectiveness. We assess the full extent of storm and hail damage promptly to minimize risk.



Repairs include panel replacement, sealant renewal, and refastening areas that have shifted or loosened. We also ensure all repairs meet local building codes and industry standards for durability.

Proper care and timely support ensure your metal roof stays durable and leak-resistant. Consistent upkeep prevents rust and damage caused by weather conditions. Understanding maintenance tasks and warranty options helps protect your investment effectively.


Routine Maintenance Recommendations


Regular inspections are essential to identify issues early. We recommend checking your roof at least twice a year, especially after harsh weather. Look for loose fasteners, rust spots, and damaged panels.


Cleaning debris like leaves and dirt prevents moisture buildup, which can accelerate corrosion. Use a soft brush and mild detergent to avoid scratching the surface. Avoid harsh chemicals or pressure washing, as they may damage protective coatings.

Our service includes clear warranty terms covering labor and materials for metal roof repairs. We ensure you understand the coverage limits and duration before starting any work.

Frequently Asked Questions About Metal Roof Repair


  • How much does metal roof repair cost?

    Metal roof repair costs vary depending on the type of damage, roof accessibility, and materials needed. Minor repairs like loose fasteners or small punctures typically cost less than extensive work involving panel replacement or structural issues. At Janesville Superior Roofing, we provide detailed free estimates that specify all materials and labor required. Metal roof repairs are generally more cost-effective than replacement and can extend your roof's lifespan.

  • What does professional metal roof repair include?

    Professional metal roof repair includes thorough damage assessment, secure fastening of loose panels, sealing of penetrations and seams, replacement of damaged fasteners with proper screws and washers, and touch-up painting to prevent rust. We also inspect and repair flashing around chimneys, vents, and roof penetrations, check gutters and trim connections, and ensure proper drainage.

  • Do you offer emergency metal roof repair services?

    Yes, we provide 24/7 emergency metal roof repair services for urgent situations like storm damage, major leaks, or loose panels that pose safety risks. Our emergency response includes immediate temporary stabilization to prevent further damage, followed by permanent repairs once conditions permit. We prioritize emergency calls and can often provide same-day service for critical issues. 

  • Can rusted metal roofing be repaired?

    Yes, rusted metal roofing can often be repaired depending on the extent and location of the corrosion. Surface rust can be treated by removing loose material, applying rust inhibitors, and recoating with matching paint systems. More extensive rust may require panel replacement or reinforcement with compatible materials. We assess each situation individually, as some advanced corrosion may make replacement more economical than repair. 

  • Why is my metal roof making loud noises during storms?

    Loud noises during storms typically indicate loose fasteners, inadequate fastening patterns, or thermal expansion issues. Wind can cause loose panels to vibrate or lift, creating banging or flapping sounds. Insufficient attachment points allow panels to move excessively during weather events. Temperature changes cause metal to expand and contract, which can create popping or crackling sounds if the roof lacks proper expansion joints.
