How Do You Repair an EPDM Roof? | Astral Roofing and Building Ltd

As a homeowner, maintaining the integrity of your EPDM roof is essential to safeguarding your property. When faced with repairs, the decision between handling the task yourself or seeking professional assistance can be intimidating.

Repair an EPDM roof by first inspecting for punctures or tears. Understanding the scope of common EPDM roof problems and the appropriate DIY repair techniques is necessary. Knowing when to take matters into your own hands and when to call a pro can make all the difference in the longevity and effectiveness of your roof repair efforts.

What Causes Typical EPDM Roof Problems?

Prolonged exposure to UV radiation, temperature fluctuations, poor installation, and lack of regular maintenance are primary causes of EPDM roof problems. UV exposure degrades the membrane, causing cracks and leaks, while temperature changes lead to material stress and tears.

Improper installation, such as inadequate adhesion and poorly sealed seams, allows water infiltration and creates wrinkles and air bubbles that trap moisture. Regular inspections can catch minor issues early, but neglecting maintenance leads to debris accumulation and water pooling, exacerbating leaks.

Physical damage from foot traffic or falling objects can puncture the membrane, especially on roofs accessed for HVAC maintenance. Protective measures like walkway pads help reduce this risk. By addressing these factors, property owners can extend the lifespan of their EPDM roofing systems.

What Materials Are Needed for EPDM Roof Repair?

To repair an EPDM roof, you need specific materials for a durable fix. Materials you will need for the repair are:

Rubber gloves
EPDM roofing primer
EPDM lap sealant
Cleaning brush and rags for debris removal
Weathered membrane cleaner to eliminate oxidation
EPDM rubber membrane (at least 0.060 inches thick)
Scissors for cutting the patch
Paint roller or brush
Seam roller
Appropriate adhesive (pressure-sensitive patches or splice adhesive)

How To Repair EPDM Rubber Roof?

Repairing an EPDM roof involves a systematic process to ensure durability. Here are the steps you can follow to repair your EPDM roof:

First, inspect the membrane for punctures, tears, or other damage.
Next, clean the roof surface using a weathered membrane cleaner and brush to remove contaminants.
Cut a repair patch to extend at least two inches beyond the damaged area.
Apply the appropriate adhesive to both the patch and the damaged area, allowing it to flash off until no longer tacky.
Attach the patch by removing the paper backing, if pressure-sensitive, or place the adhesive-coated patch onto the EPDM surface, using a roller to eliminate air bubbles and ensure a secure bond.

What Are the Essential DIY EPDM Roof Repair Techniques?

To effectively address minor damages on an EPDM roof, utilizing appropriate do-it-yourself repair techniques can help maintain the integrity of the roofing system and prevent further issues. When dealing with small punctures or tears in the EPDM membrane, a DIY approach can be cost-effective and relatively simple if done correctly.

DIY EPDM Roof Repair Techniques	Description
Patch Kits	Utilize EPDM patch kits designed for repairing small punctures or tears. These kits typically include adhesive and a patch that can be applied to the damaged area.
Cleaning and Priming	Thoroughly clean the damaged area with a suitable cleaner and primer before applying any repair materials to guarantee proper adhesion.
Seam Repair	Use seam repair products to fix any separations or damage along the seams of the EPDM membrane.
Flashing Repair	Address any issues with flashing around vents, skylights, or other penetrations on the roof to prevent leaks.
Regular Inspections	Conduct regular inspections to detect minor damages early and prevent them from escalating into larger problems.

Can I Patch the EPDM Roof?

Yes, you can patch an EPDM roof. EPDM roofs are durable and easy to maintain, making them suitable for patching minor punctures or small tears. An EPDM rubber roof repair kit, typically including a patch, adhesive, and tools, is used.

First, inspect and clean the surface to remove debris and oxidation. Size and cut the patch to extend at least two inches beyond the damaged area. Apply a thin layer of primer to the cleaned surface, extending slightly beyond the patch edges. Affix the patch using a pressure-sensitive adhesive or separate adhesive, then use a roller to ensure adhesion and expel air. Finally, apply an EPDM lap sealant around the patch edges to prevent water infiltration.

Can You Install EPDM Over Existing EPDM?

Yes, you can install an EPDM membrane over the existing EPDM roof, providing a barrier layer such as 5/8’ plywood, OSB board, or polyisocyanurate board with a fibreglass backing is first applied. This barrier layer ensures proper adhesion and protection for the new membrane.

The barrier prevents direct contact between the new and old EPDM layers, avoiding adhesion issues and enhancing durability. It provides a smooth, uniform surface for a watertight seal and addresses underlying issues like minor damages or uneven surfaces.

Ensure the existing EPDM roof is clean, dry, and debris-free before placing the barrier layer. Securely fasten the barrier layer to the existing roof, making sure it is level and stable. Then, apply adhesive to the barrier layer and roll out the new EPDM membrane, pressing it firmly into place.

What Are the Signs That You Need Professional Roofers?

Persistent leaks, visible tears, punctures, or blistering on the roof surface indicate the need for professional roofers. Water stains on ceilings or walls suggest compromised EPDM membranes. Increased energy bills may signal impaired insulation.

Mould or mildew presence, sagging or uneven roof surfaces, and roofs nearing or exceeding their 20-30-year lifespan also require professional assessment. Engaging experienced contractors ensures thorough and effective issue resolution.

How Can You Choose the Best Roofing Contractors for Your EPDM Roofing System?
