Is Your Flat Roof in Need of Repair?
Leaks or Water Stains
The most obvious sign of a problem, often appearing on the ceiling below the flat roof.
Pooling or Standing Water
Water that sits on your flat roof for more than 48 hours indicates improper drainage.
Visible Damage
Look for cracks, blisters, bubbles, or tears in the flat roof membrane.
Sagging Roofline
A sagging flat roof can indicate a major structural problem or waterlogged decking.
Moss or Plant Growth
Extensive growth can trap moisture and cause the membrane to deteriorate.
Increased Energy Bills
An old or poorly installed flat roof can lack proper insulation, leading to heat loss.
Trade is full of uncertainty. We remove it.

The true cost of cheap work.
A low quote for a flat roof can be tempting, but poor workmanship isn't just cosmetic -- it can lead to serious, expensive problems.
Incorrect Drainage
Leads to standing water, which puts stress on the membrane and causes leaks.
Substandard Materials
Cheap materials won't stand up to Plymouth and Devon's weather, leading to premature failure.
Poorly Sealed Joints
Joints that aren't sealed correctly can open up and allow water to get in.
Bad Edge Detailing
Poorly installed flashing can cause water to seep behind the membrane and rot the decking.
Lack of Insulation
Overlooked insulation leads to heat loss and higher energy bills.
