Our Commercial Flat Roof Repair Process
Detailed Roof Inspections & Reporting
We begin with a comprehensive roof inspection, using moisture meters and visual checks to assess the extent of the damage. You’ll receive a clear, no-jargon report with photos.
Pinpointing the Root Cause of Damage
Many repairs fail because they treat the symptom, not the cause. We address underlying issues such as poor drainage, defective flashings, or damaged insulation.
EPDM, GRP, and Felt Roof Repair Solutions
Our team is skilled in repairing all major flat roof systems, including EPDM rubber roofing repairs with seamless patches and sealing to stop leaks, GRP fibreglass roof repairs by re-laminating worn sections for watertight protection, and bitumen and felt roof repairs using hot torch-on applications for maximum durability.
Quality Checks & Long-Term Guarantees
Every repair is inspected, tested, and backed by a written warranty for peace of mind.

Frequently Asked Questions (FAQs)
How long does a commercial flat roof repair last?
A quality repair can last anywhere from 5 to 15 years, depending on the material type, exposure to UV light, and the roof’s overall condition.
Using high-grade repair compounds and ensuring proper surface preparation significantly extends the repair’s performance life.
Can you repair a roof instead of replacing it?
Yes — in many cases, targeted repairs can extend the life of your roof without the cost of full replacement.
This is especially true when the substrate and insulation remain sound, allowing us to overlay or patch the existing membrane to modern waterproofing standards.
What is the fastest way to fix a leak?
Emergency patching can stop water ingress immediately, but we always recommend a permanent repair soon after.
The fastest effective solution involves locating the exact failure point, cleaning and priming the surface, and applying a compatible membrane patch with full edge sealing.
How much does flat roof repair cost in Reading?
Costs vary based on size, material, and severity of the issue. Factors such as roof accessibility, required safety measures, and material compatibility can also influence pricing, which is why we provide detailed, itemised quotations after the roof inspection.
What is the Longest Lasting Flat Roof Material?
GRP (Glass Reinforced Plastic) is widely considered the most durable flat roofing material on the market, with a lifespan that can exceed 40 years. It’s particularly valuable in demanding commercial environments, where consistent performance is critical.
GRP forms a fully bonded, seamless membrane, making it resistant to leaks, UV degradation, and structural movement. It’s a top choice for buildings with roof access walkways, solar panels, or plant equipment.
Although the initial investment in GRP is higher, its long-term reliability and minimal maintenance make it a smart business decision for those looking to reduce future disruption and repair costs.
We’ll guide you through the decision, factoring in your building’s usage, compliance requirements, and return on investment.
