Membrane Repairs


At A. Armstrong Roofing, we specialise in high-quality membrane repairs for flat roofs, ensuring your property remains watertight, protected, and structurally sound. Whether your existing membrane is leaking, cracked, or showing signs of wear, our experienced team can restore your roof using reliable methods and premium materials.


We work with EPDM (rubber). Our NFRC-certified team offers durable, weather-resistant solutions tailored to your property's unique needs.

Common Membrane Issues We Repair:

  • Cracks or blisters in the roofing membrane
  • Leaks or water ingress in flat roof areas
  • Ponding water due to poor drainage
  • Damaged seals or lifting membrane edges
  • UV degradation or age-related wear


These problems can quickly escalate and lead to internal damage, mould, and costly structural repairs. Our quick response and professional service ensure lasting protection and peace of mind.
