When it comes to maintaining a commercial or residential flat roof, one of the most common dilemmas property owners face is whether to invest in roof restoration or complete roof replacement. EPDM (Ethylene Propylene Diene Monomer) roofs are well-suited for restoration projects. However, in some cases, a complete replacement may be necessary.
What Is EPDM Roof Restoration?
EPDM roof restoration is applying a protective coating or membrane over an existing EPDM roof. This restores the roof’s waterproofing capabilities, fixes minor damage like cracks and leaks, and protects against UV rays, weathering, and other environmental factors.
Restoring an EPDM roof typically involves cleaning the surface, repairing any minor damage, and applying a liquid rubber or elastomeric coating to seal the roof. This process can extend the life of your roof by 10-20 years and is ideal for roofs that are still structurally sound but showing signs of aging or minor wear and tear.
What Is Roof Replacement?
Roof replacement, on the other hand, involves removing the old roofing materials and installing an entirely new roof. For EPDM roofs, this usually means stripping the existing rubber membrane, repairing or replacing the underlayment, and installing new EPDM or another roofing material. Roof replacement is a much larger and more expensive project.
The Benefits of EPDM Roof Restoration
Cost-Effectiveness
The most apparent advantage of EPDM roof restoration is the cost. Since restoration doesn’t involve removing the old roof, the labor and material costs are significantly lower. You can save up to 50% compared to a complete roof replacement. This makes restoration attractive for property owners looking to maintain their roofs without breaking the bank.
Less Disruption
Roof restoration is a quicker and less invasive process. There’s no need to tear off the old roof, so your daily operations won’t be as affected. This mainly benefits businesses or homeowners who want to avoid the noise, debris, and disruption often accompanying a total roof replacement.
Eco-Friendly
Restoration is a more environmentally friendly option since it reduces the amount of roofing material in landfills. Extending the life of your current roof also delays the need for new materials, further minimizing your environmental impact.
When Should You Choose Roof Replacement?
Severe Damage
If your EPDM roof has extensive damage—such as large cracks, multiple leaks, or compromised insulation—restoration may not be enough to solve the problem. In cases where the roof’s structural integrity has been compromised, a total roof replacement is a safer and more effective option.
Multiple Layers of Roofing
If your roof already has multiple layers of material from previous restorations or repairs, adding another layer might not be practical or safe. Building codes often limit the number of layers a roof can have. In these cases, replacing the entire roof may be the best solution.
Old Age
If your EPDM roof is nearing the end of its lifespan (typically around 20-30 years), restoration may only provide a temporary fix. A roof replacement could be a better long-term solution, especially if the roof has been neglected or improperly maintained over the years.
Final Thoughts
In the debate between EPDM roof restoration and roof replacement, the right choice depends mainly on your roof’s condition, budget, and long-term goals. Restoration is an excellent, cost-effective option for roofs that are still structurally sound but require additional protection and minor repairs.
On the other hand, if your roof has extensive damage or is reaching the end of its lifespan, replacement might be the better investment for long-term durability.
