When to consider our
Flat Roof Services
Persistent Leaks
If your flat roof is continually leaking, especially in multiple spots, it's a strong indicator that a repair or replacement is needed.
Age of Roof
Most flat roof systems have a lifespan (e.g., felt 10-20 years, EPDM/GRP 20-50+ years). If yours is nearing or past its expected life, consider a replacement.
Visible Damage
Cracks, blisters, bubbles, splits, tears, or a general degraded appearance of the flat roof membrane.
Sagging or Spongy Areas
Can indicate water saturation in the underlying layers or structural issues.
Pooling Water
Standing water on your flat roof for extended periods can cause membrane deterioration and lead to leak.
Mould or Damp Indoors
Signs of moisture inside your property, particularly on ceilings or walls adjacent to a flat roof.
