Flat and low-pitch roofs demand specialist knowledge and materials different from traditional pitched roofing. D.A Dancer Roofing Specialists brings over three decades of flat roofing expertise to Lowestoft, installing modern EPDM systems, durable GRP fibreglass and traditional built-up felt roofs. Whether you need a new installation, complete replacement or repairs to existing flat roofing, we deliver watertight solutions that perform reliably for decades.

MATERIAL SYSTEMS

Modern Flat Roofing Materials

EPDM Rubber Systems

Single-ply EPDM membranes have revolutionised flat roofing over the past two decades. These synthetic rubber sheets provide excellent weather resistance, UV stability and flexibility across wide temperature ranges. EPDM systems can last 40-50 years whilst requiring minimal maintenance. We install EPDM using both fully-adhered and mechanically-fastened methods depending on substrate conditions.

Traditional Felt Systems

Built-up felt roofing using three layers of bituminous felt remains viable for budget-conscious applications. Modern torch-on felt provides better performance than older systems, whilst remaining economical to install. Three-layer systems use different felt types for base, middle and cap layers. Well-installed felt systems last 15-25 years depending on quality and maintenance.

OUR PROCESS

Our Installation Process

1

Substrate Preparation

Successful flat roofing begins with proper substrates. We install decking over roof joists, ensuring adequate falls towards drainage points. Decking must be stable, smooth and dry before membrane installation begins. Insulation installation often occurs during flat roof projects, meeting building regulations thermal requirements.

2

Drainage Design

Effective drainage is critical for flat roof performance. We install outlets positioned at low points, ensuring positive drainage of rainwater. Overflow outlets provide backup drainage preventing catastrophic flooding if primary outlets block. We ensure proper falls throughout, avoiding areas where water might pond.

3

Membrane Installation

Each membrane type requires specific installation techniques. EPDM involves laying and adhering large sheets with carefully sealed seams. GRP uses wetlay techniques building up fibreglass layers. Felt requires systematic torch-application creating bonded multilayer systems. Edge details, penetrations and upstands receive particular attention.

4

Quality Assurance

Upon completion, we flood-test roofs when practical, checking that all areas drain properly and no leaks exist. Visual inspections verify that all details meet our standards. We provide care instructions helping you maintain your new roof properly.

REPAIRS

Flat Roof Repairs

Blistering and Bubbling

Trapped moisture beneath membranes creates blisters that eventually split, allowing water penetration. Repairs involve cutting out blistered areas, drying substrates and patching with compatible materials. Extensive blistering might indicate substrate moisture problems requiring comprehensive solutions.

Seam Failures

Felt roof seams can separate through thermal movement or inadequate initial bonding. EPDM seams occasionally lift if adhesive fails. Repairs require proper surface preparation and compatible sealants or patches ensuring watertight results.

Ponding Issues

Water collecting in depressions indicates drainage problems that will progressively worsen. Solutions might include additional outlets, firring pieces creating improved falls or complete overlay systems establishing proper drainage.

Flashing Failures

Upstand flashings around parapets, walls and penetrations commonly fail through movement or deterioration. Repairs involve installing proper lead or compatible flashings ensuring weathertight junctions.

GUARANTEES & EXPERTISE

Guarantees & Specialist Expertise

Material manufacturers provide warranties ranging from 10 years for felt to 20-40 years for EPDM and GRP systems. Our workmanship guarantee typically covers 10-15 years demonstrating confidence in installation quality. Our specialist flat roofing knowledge comes from decades of installing and maintaining these systems throughout Lowestoft.
