Expert Guide To Rubber Roofing Repairs: Common Issues & Solutions

Rubber Roofing Repairs

Rubber roofing has gained popularity in Canada due to its durability, flexibility, and resistance to extreme weather conditions. However, like any roofing material, rubber roofs are not immune to issues over time. In this comprehensive guide, we’ll explore the common problems encountered with rubber roofing systems and provide expert solutions for effective repairs.

Understanding Rubber Roofing

Rubber commercial roofing in Calgary, also known as EPDM (ethylene propylene diene terpolymer) roofing, is a synthetic material widely used for flat and low-slope roofs. Its resilience against UV rays, moisture, and temperature variations makes it a preferred choice for commercial and residential buildings alike. Despite its durability, rubber roofs can experience several issues that require prompt attention to prevent further damage.

Common Issues With Rubber Roofing

  1. Punctures and Tears: Sharp objects or foot traffic can cause punctures and tears in rubber roofing membranes, leading to water infiltration and potential leaks.
  2. Joint and Seam Problems: Improper installation or aging can result in loose joints and seams, allowing water to seep through and compromise the roof’s integrity.
  3. Blistering and Bubbling: Excessive moisture trapped beneath the rubber membrane can cause blistering and bubbling, indicating potential adhesion issues or moisture intrusion.
  4. UV Damage: Over time, prolonged exposure to UV rays can degrade the surface of rubber roofs, leading to cracking, fading, and reduced elasticity.
  5. Pooling Water: Poor drainage or clogged gutters can cause water to pool on the roof, creating stress on the membrane and increasing the risk of leaks and structural damage.

Effective Repair Solutions

1. Patch & Seal Punctures: 

Small punctures and tears can be repaired using rubber patching materials and sealants. Clean the damaged area thoroughly, apply the patch with adhesive, and seal the edges for a watertight seal.

2. Reinforce Joints & Seams: 

Address loose joints and seams by applying seam tape or liquid seam sealant along the affected areas. Ensure proper adhesion and seam reinforcement to prevent water intrusion.

3. Address Blistering: 

For blistered areas, carefully cut open the blister, dry the underlying membrane, apply adhesive, and press the membrane back in place. Use a roller to ensure proper bonding and eliminate air pockets.

4. UV Protection Coatings: 

Apply UV-resistant coatings or paints specifically designed for rubber roofs to protect against UV damage and extend the roof’s lifespan. Ensure thorough cleaning and priming before applying the coating for optimal adhesion.

5. Improve Drainage: 

Address drainage issues by clearing debris from gutters and downspouts, installing additional drains or scuppers, and ensuring proper slope and flow of water away from the roof surface.

Preventive Maintenance Tips

  1. Regular Inspections: Schedule routine inspections of your rubber roof to identify potential issues early and address them promptly.
  2. Clean Debris: Keep the roof surface clean and free of debris, including leaves, branches, and dirt, to prevent water pooling and moisture retention.
  3. Trim Overhanging Branches: Trim trees near the roof to prevent branches from rubbing against or falling onto the rubber membrane, causing damage.
  4. Professional Maintenance: Consider hiring professional roofing contractors for annual maintenance, inspections, and repairs to ensure thorough care and optimal performance of your rubber roof.


By understanding the common issues faced by rubber roofing systems and implementing effective repair solutions and preventive maintenance practices, property owners can prolong the lifespan of their roofs and avoid costly repairs. Regular inspections, prompt repairs, and professional maintenance are key elements in preserving the durability and integrity of rubber roofs, ensuring long-term protection against the elements and maintaining a secure and watertight building envelope.

In conclusion, proactive maintenance and timely repairs are paramount in ensuring the longevity and performance of rubber roofing systems. By addressing common issues such as punctures, seam problems, blistering, UV damage, and drainage issues promptly and effectively, property owners can safeguard their investments and avoid costly damages. Additionally, incorporating preventive maintenance measures such as regular inspections, debris removal, and professional maintenance services can significantly extend the lifespan of rubber roofs and enhance their resilience against harsh weather conditions.

It’s crucial for property owners to partner with experienced roofing professionals who specialize in rubber roofing repairs and maintenance. These experts can offer tailored solutions, expert advice, and quality workmanship to keep rubber roofs in optimal condition year-round. By investing in the care and maintenance of rubber roofing systems, property owners not only protect their properties from water damage and structural issues but also contribute to a sustainable and resilient building environment. Stay proactive, stay informed, and prioritize the health of your rubber roof for long-term reliability and peace of mind.
