How Do I Check If My Roof's Membrane Is Perished?

Welcome to Countrywide Insulation's official blog, your trusted source for insulation solutions and roof maintenance. Today, we address a common concern among homeowners and property managers: How can you determine if your roof's membrane has perished?

Understanding Roof Membranes:

Before we delve into the methods for checking the condition of your roof's membrane, let's first understand what a roof membrane is. The roof membrane is a critical component of any building's roofing system, serving as a protective layer that shields the structure from water, UV rays, and other environmental elements. It's typically made from materials such as modified bitumen, EPDM (ethylene propylene diene terpolymer), PVC (polyvinyl chloride), or TPO (thermoplastic polyolefin).

Signs of a Perished Roof Membrane:

Detecting signs of membrane deterioration early on is crucial to preventing costly damage to your property. Here are some indicators that your roof membrane may be perished:

  1. Leaks: Water stains or dripping water inside the building are clear signs of roof membrane damage.
  2. Blisters or Bubbles: Raised areas on the roof surface, often filled with water or air, indicate membrane degradation.
  3. Cracks or Splits: Visible cracks or splits in the membrane can compromise its integrity and lead to leaks.
  4. Ponding Water: Pooled water on the roof surface due to inadequate drainage or membrane damage can accelerate deterioration.
  5. Tears or Punctures: Physical damage to the membrane, such as tears or punctures, can expose the underlying layers to moisture and UV radiation.

Methods for Inspection:

Now that we've identified potential signs of membrane deterioration let's explore some methods for inspecting your roof:

  1. Visual Inspection: Examine the roof surface from ground level or using a ladder. Look for any signs of damage, including cracks, tears, or blistering.
  2. Roof Walk: If it's safe, walk carefully on the roof surface for a more thorough inspection. Pay close attention to seams, flashings, and areas prone to ponding water.
  3. Moisture Survey: Utilise moisture detection tools such as infrared thermography or capacitance meters to identify areas of trapped moisture within the roof system.
  4. Professional Inspection: For a comprehensive assessment, consider hiring a licensed roofing contractor or building inspector to evaluate the condition of your roof membrane.


In conclusion, regular inspection and maintenance are essential for preserving the integrity of your roof membrane and extending its lifespan. By being proactive and attentive to signs of deterioration, you can address issues promptly and avoid costly repairs down the road. If you suspect that your roof membrane may perish or is in need of attention, don't hesitate to reach out to the experts at Countrywide Insulation for professional guidance and assistance.
