So Why Use Professionals for Flat Roofing Installation in London
If you’re considering a flat roofing installation in London, it’s essential to work with experienced professionals who understand the challenges posed by urban properties, building access, and variable weather conditions. Whether you’re planning a new build, an extension, or replacing an existing flat roof, choosing the right system and contractor ensures long-term performance, proper drainage, and weather protection.
In this blog, we explain the types of flat roofing systems used in London, what the installation process involves, and how to choose a reliable local roofer.
Why Choose Flat Roofing?
Flat roofs are a popular choice in many parts of London, particularly for:
- Rear extensions and kitchen additions
- Garages, garden offices, and outbuildings
- Apartment blocks and commercial buildings
- Roof terraces and balconies
Their straightforward design makes them space-efficient and cost-effective. However, correct installation is crucial to avoid common issues such as pooling water, leaks, or material failure.
Flat Roofing Materials Used in London
When it comes to flat roofing installation in London, there are several systems to choose from depending on budget, property type, and performance expectations:
Felt Roofing
- Cost-effective and suitable for small to medium-sized roofs
- Installed using a torch-on method
- Offers 10–15 years of protection when maintained properly
GRP (Fibreglass) Roofing
- Durable, seamless, and resistant to water and impact
- Ideal for domestic extensions
- Life expectancy of 20–30 years
EPDM (Rubber) Roofing
- Flexible and lightweight
- Suits larger surface areas
- Lasts up to 25 years with minimal maintenance
Liquid Roofing Systems
- Applied cold using a brush or roller
- Ideal for awkward or complex roof shapes
- Provides a seamless, waterproof barrier
A good roofing contractor will assess your structure and recommend the best option based on use, budget, and location.
What’s Involved in a Flat Roof Installation?
Professional flat roofing involves a detailed, multi-step process:
1. Site Inspection and Planning
Your roofer will visit the property to assess the area, drainage requirements, access points, and structural condition.
2. Removal of the Old Roof (if applicable)
If replacing an old roof, materials such as felt or insulation are carefully removed and disposed of. The roof deck is inspected for rot or structural damage.
3. Installation of Insulation and Decking
Flat roofs must comply with current UK building regulations, which require adequate insulation. A new deck is laid if needed, providing a strong, level base.
4. Fitting the Waterproof System
Your chosen material—whether felt, EPDM, GRP, or liquid—is installed to manufacturer specifications. Edge trims, upstands, and outlets are also fitted to ensure proper water flow.
5. Final Inspection and Clean-Up
The roofer checks for waterproofing, secure finishes, and correct drainage. Once approved, all waste is removed from site.
Local Experience Matters in London
Installing flat roofs in London requires practical knowledge of:
- Limited access in urban streets
- Fire safety regulations, especially for extensions
- Drainage and run-off management
- Planning restrictions in conservation areas
Local roofers understand the borough-specific challenges and can offer practical solutions to work within those limits. They’ll also be able to support you with building control and planning approval if needed.
Signs You Need a Flat Roof Replacement
Even a well-installed flat roof will eventually need replacing. Signs it’s time to consider a new flat roofing installation include:
- Persistent leaks or ponding water
- Blistering or cracking across the surface
- Roof sagging or structural movement
- Repairs becoming frequent or ineffective
If your roof is over 20 years old or has visible deterioration, it’s more cost-effective to replace it fully than to continue patching.
How to Choose the Right Flat Roofing Contractor
When planning a flat roofing installation in London, choose a contractor who:
- Offers written, itemised quotes
- Has experience with London property styles
- Uses high-quality materials with manufacturer guarantees
- Complies with local and national building regulations
- Is reviewed positively on platforms like Checkatrade’s Roofing Hub
Avoid companies that offer vague pricing or pressure you into decisions. Reliable roofers will explain all your options clearly and honestly.
