Flat Roof Replacement | Medway, Kent
Primeline Roofing recently completed a large flat roof replacement for a residential property in Medway, Kent, installing a modern 3-layer torch-on felt roofing system designed for long-term durability and weather protection.
The existing roof had deteriorated over time, showing signs of surface wear, patch repairs, and areas where water was beginning to sit on the surface. The homeowner wanted a reliable, long-lasting flat roofing solution that would protect the property from the unpredictable Kent weather.
Our team recommended a professional 3-tier torch-on felt system, which provides excellent waterproofing and is widely used for flat roofs on homes across Medway, Chatham, Gillingham, Rochester, and the wider Kent area.
Roof Preparation & Cleaning
Every successful flat roof installation begins with careful preparation.
Before installing the new roofing system, our team carried out a full roof clean and inspection, removing debris, dirt, and any loose materials from the surface. Proper preparation ensures the torch-on membranes bond correctly to the roof deck.
During this stage we also inspected:
Roof edges and perimeter trims
Drainage outlets and roof falls
Flashing details around chimneys and walls
Any areas of previous repair
This process ensures the new roofing system can be installed safely and perform effectively for many years.
Installation of the 3-Layer Torch-On Felt System
Once the roof surface had been prepared, our roofers installed a professional 3-layer torch-on felt system using specialist gas torch equipment.
This high-performance flat roofing system included:
Base Layer Installation
The base layer provides the foundation of the roofing system and prepares the surface for the waterproof membranes.
Reinforced Underlay Membrane
A durable waterproof underlay was heat-bonded to the roof surface. Using a blowtorch, the bitumen backing melts and bonds firmly to the deck and adjoining sheets, creating a strong waterproof barrier.
Mineral Cap Sheet (Top Layer)
The final stage involved installing a heavy-duty mineral cap sheet, which forms the visible surface of the roof. This protective layer helps shield the roof from:
Rain and standing water
UV damage
Temperature fluctuations
General weather exposure
The mineral finish also improves the durability of the roofing system and gives the roof a clean, professional appearance.
Completed Flat Roof in Medway
The finished installation provides the property with a strong, fully waterproof flat roof system built to withstand the changing weather conditions experienced across Medway and Kent.
By installing a 3-layer torch-on felt roof, the homeowner now benefits from:
Long-lasting waterproof protection
High-strength bonded roofing layers
Improved durability and weather resistance
A neat, uniform roof finish
Torch-on felt systems can typically last 15–20 years or more when professionally installed, making them a popular and cost-effective flat roofing option for homes throughout Medway and Kent.
