Detailed Service Guide

Flat roofing demands an incredibly high level of precision and expertise, as the margin for error is significantly smaller than with pitched roofs. Due to their minimal gradient, flat roofs must rely entirely on the absolute integrity of their waterproofing membrane rather than gravity. We specialise in the installation and repair of advanced flat roofing systems specifically engineered to withstand pooling water, thermal expansion, and prolonged UV exposure.

Modern flat roofing has evolved drastically from the traditional pour-and-roll felt systems of the past. Today, we utilise high-performance materials such as Torch-on modified bitumen, seamless EPDM rubber, and GRP fibreglass. Each system offers distinct advantages depending on the application—whether it's a residential extension, a garage, or a commercial premise. Our team carefully assesses the structural deck, ensuring the correct subtle falls are in place to promote efficient drainage and prevent standing water.

A successful flat roof installation is defined by the quality of its edge details and abutments. We pay fastidious attention to the installation of perimeter trims, upstands, and lead flashings where the flat roof meets the main building. By ensuring these critical junction points are flawlessly sealed, we eliminate the most common causes of flat roof failure, delivering a sleek, modern finish backed by formidable long-term durability.

Warning Signs & When to Act

• Extensive Water Pooling: Large puddles remaining on the roof surface for more than 48 hours after rain, indicating poor drainage falls.
• Blistering and Bubbling: Air or moisture trapped beneath the membrane expanding in the sun, which eventually cracks the surface.
• Cracking at the Edges: The perimeter seals or upstands pulling away from the brickwork, leaving a clear path for water ingress.
• Spongy Roof Deck: The roof feels soft or gives way underfoot, indicating that the underlying timber decking has rotted.

Scope of Work

We install and repair Torch-on Felt, GRP fiberglass, and EPDM rubber roofing systems. We also adjust timber decking to ensure proper drainage falls.

Our Process

1. Assessment of the existing deck for rot or moisture damage.
2. Correction of drainage falls if necessary.
3. Application of the chosen flat roofing membrane.
4. Sealing of all edge trims and wall abutments.

Inspection & Quality Checks

• Thorough moisture mapping of the existing deck to ensure no dampness is trapped beneath the new system.
• Laser-level checking of the drainage falls to guarantee water flows efficiently to the outlets.
• Stress-testing of all heat-welded or chemically bonded seams to ensure absolute watertight integrity.
• Detailed inspection of all edge trims, wall abutments, and lead flashings prior to sign-off.

Project Preparation

If your flat roof is situated above a sensitive area, such as a kitchen or living room, we advise removing high-value items from directly beneath the ceiling during the deck replacement phase to protect them from dust or minor vibrations.

Aftercare & Maintenance

Flat roofs require slightly more diligent housekeeping than pitched roofs. It is essential to carefully sweep away heavy accumulations of autumn leaves and debris at least twice a year to ensure the drainage outlets do not become blocked and cause water to back up.

Quotation Checklist

• Ensure the quote specifies the exact flat roofing system (e.g., EPDM, GRP, or 3-layer Torch-on felt).
• Check if the cost includes the removal and replacement of rotten timber decking if discovered.
• Verify that new edge trims and associated wall flashings are explicitly itemised.
• Confirm the expected lifespan of the system and the details of the accompanying guarantee.

FAQs

How long does a flat roof last?

A professionally installed flat roof using modern materials like EPDM or GRP can last 20-30 years or more.

Are flat roofs prone to leaking?

Historically yes, but modern seamless materials are highly resistant to leaks when properly installed by our experts.

Do you repair existing flat roofs?

Yes, we handle everything from minor patching of small tears to complete flat roof deck replacements.

Can I walk on my new flat roof?

Standard flat roofs are not designed for heavy foot traffic, but we can reinforce the deck and use specific finishes if you need a balcony area.

What is the best material for a flat roof?

It depends on the size and usage. EPDM is excellent for longevity, while Torch-on felt remains a highly cost-effective and robust option.
