Flat roofing has become increasingly popular for both modern residential properties and commercial buildings—and for good reason. This roofing style offers a clean, contemporary appearance while delivering impressive durability and low-maintenance performance.
Unlike traditional pitched roofs, flat roofs optimize space efficiency. They provide additional usable area that can be transformed into rooftop terraces, support solar panel installations, or even accommodate environmentally friendly green roofs.
With advancements in roofing technology, materials such as EPDM (ethylene propylene diene monomer), TPO (thermoplastic polyolefin), and GRP (glass-reinforced plastic) now offer superior resistance to harsh weather conditions, improved energy efficiency, and extended lifespan.
Whether you're planning a new flat roof installation or need to repair an existing one, working with experienced, certified roofing specialists is essential. The right professionals will not only ensure structural integrity and compliance with local building regulations but also maximize the long-term value of your investment.

Standing water on a flat roof can lead to leaks, structural damage, and premature deterioration. Proper drainage is essential to prevent costly repairs.
Air or moisture trapped beneath the roofing membrane can cause bubbles or blisters, weakening the roof and increasing the risk of leaks.
Shifts in the building structure or aging materials can cause the roofing membrane to wrinkle or buckle, reducing its effectiveness and durability.
Cracking patterns resembling alligator skin occur due to prolonged sun exposure and aging, signaling that the roof may need replacement
Poor drainage and accumulated debris can lead to plant growth, which retains moisture and accelerates roof degradation.
Temperature fluctuations cause expansion and contraction of roofing materials, leading to cracks, weakened seams, and potential leaks over time.
Our company also has valid certificates FSC and PEFC.

If your flat roof has frequent leaks, visible cracks, ponding water, or signs of aging like blistering or alligatoring, it may require repair or replacement. A professional inspection can determine the best solution.
The lifespan depends on the material used:
EPDM rubber – 25-30 years
TPO & PVC – 20-25 years
GRP (Fiberglass) – 20-30 years
Bitumen/Felt – 10-20 years
Regular maintenance can extend its durability.
Some of the most common flat roof problems include:
Ponding water (standing water that can lead to leaks)
Blistering (bubbles caused by trapped moisture)
Buckling (roof membrane shifting or wrinkling)
Alligatoring (cracking due to aging and sun damage)
Moss and weed growth (causing trapped moisture and deterioration)
Thermal movement (expansion and contraction leading to cracks)
The cost varies based on the size of the roof, material used, and labor. On average, flat roof replacement can range from £50 to £120 per square meter in the UK. Contact us for a free quote!
A typical flat roof replacement takes 1 to 3 days, depending on the size and complexity of the project. Repairs can often be completed in a few hours.
Ensure proper drainage to prevent ponding water.
Schedule regular maintenance and inspections.
Use high-quality waterproofing materials.
Fix small issues like cracks and blisters early before they worsen.
In some cases, a new membrane can be installed over the existing roof if the structure is still sound. However, if there are significant issues like water damage, a full replacement is recommended.
Flat roofs need regular inspections (at least twice a year) and occasional cleaning to prevent debris buildup, ponding water, and early wear. Proper maintenance can prevent costly repairs.
