Why a Specialist is Essential for Your Flat Roof

The term ‘flat roof’ is a bit of a misnomer. A correctly installed flat roof is never truly flat; it’s built with a slight, calculated gradient (a ‘fall’) to direct rainwater towards drainage points like gutters or outlets. Achieving this, along with creating a completely seamless and durable waterproof layer, is a specialised skill. A general builder or a roofer who primarily works on pitched slate or tile roofs may not have the specific experience required.

Hiring a dedicated flat roofing company means you are engaging a team that understands the unique challenges involved. They are experts in the modern materials and techniques that define high-quality flat roofing today. Poor installation by a non-specialist is one of the most common reasons for premature flat roof failure, leading to issues such as:

• Ponding Water:Puddles that remain on the roof 48 hours after rainfall, which can strain the structure and degrade the roof covering over time.
• Failed Seams and Joints:The most vulnerable points on many flat roof systems, which can open up if not correctly welded or bonded.
• Blistering and Tearing:Caused by trapped moisture or movement in the roof structure, which a specialist knows how to prevent.
• Inadequate Drainage:Incorrectly positioned outlets or falls that don’t effectively channel water away from the building.

A true flat roof specialist will assess your property and recommend the best system for your specific needs, budget, and the building's structure, ensuring a durable, leak-free finish that lasts for decades.

Common Services from Our Flat Roofing Specialists

Our network of flat roofing companies offers a comprehensive range of services to cover every requirement, from brand new installations to emergency repairs.

New Flat Roof Installation

If you're building a new extension, a garage, or a garden room, a new flat roof is a significant part of the project. A professional flat roofer will work from the joists up, ensuring the structural deck is sound before installing insulation to meet current Building Regulations (Part L, concerning the conservation of fuel and power) and finishing with your chosen waterproof membrane. They will ensure every detail, from the upstands and verges to the drainage, is perfectly executed.

Flat Roof Replacement

Most flat roofs have a finite lifespan. If your existing felt roof is over 15 years old, or your fibreglass roof is showing signs of widespread cracking, a full replacement may be more cost-effective than ongoing repairs. The process typically involves stripping the old covering, inspecting the timber deck for rot or damage, replacing it if necessary, and then fitting a new, modern system like EPDM or GRP that comes with a long guarantee.

Flat Roof Repair

For more isolated issues, a targeted repair can often extend the life of your roof. A skilled flat roofer can accurately diagnose the source of a leak, which may not be directly above the damp patch inside your home. They can fix punctures in a rubber membrane, patch cracks in a fibreglass system, or re-seal a failed seam on a felt roof, providing a cost-effective solution to keep your property dry.

Flat Roof Maintenance

Preventative maintenance is the best way to avoid expensive problems. A flat roofing company can offer an annual or bi-annual inspection service. This includes clearing gutters and drainage outlets of leaves and debris, checking all seals and flashings around skylights or upstands, and looking for early signs of wear and tear. This proactive approach is a small investment that can save you a fortune in the long run.

Understanding Modern Flat Roofing Materials

Technology has moved on significantly from the days of simple hot-applied tar and mineral felt. Today, homeowners have a choice of several high-performance systems, each with its own benefits. A good flat roofing specialist will be able to advise you on the best option for your home.

EPDM (Ethylene Propylene Diene Monomer)

Commonly known as rubber roofing, EPDM is a very popular choice for residential flat roofs. It is typically supplied in large, seamless sheets that are cut to the exact size of your roof, eliminating the need for joints which are often a weak point. It is bonded to the roof deck with a special adhesive.

• Lifespan:50+ years
• Pros:Extremely durable, flexible (copes well with building movement), UV resistant, and generally installed without heat or flames. Often comes in one piece, meaning no seams.
• Cons:Can be punctured by sharp objects, so it's not ideal for a roof terrace without additional protection. It requires a trained installer for a successful application.

GRP (Glass Reinforced Plastic)

Also known as fibreglass, a GRP roof is constructed in-situ by applying a layer of catalysed resin over a fibreglass mat, which then cures to form a hard, seamless, and completely waterproof shell. It's finished with a durable, coloured topcoat.

• Lifespan:25-30+ years
• Pros:Very hard-wearing and robust, can be walked on, seamless finish, and available in a wide range of colours. Ideal for complex roof shapes.
• Cons:Lacks the flexibility of EPDM, so it's not always suitable for very large roof areas. Installation is weather-dependent, as it cannot be laid in cold or damp conditions.

High-Performance Felt

This isn't the old pour-and-roll felt of years gone by. Modern bituminous felt roofing is a multi-layered system, typically applied using a large gas torch to weld the seams together. It usually consists of two or three layers to create a robust, built-up roof.

• Lifespan:15-20 years
• Pros:The most cost-effective option, a proven and reliable method, and a skill most established roofers possess.
• Cons:A shorter lifespan than EPDM or GRP. The presence of seams makes it more susceptible to failure over time, and the use of a naked flame during installation carries inherent risks if not handled by a professional.

How Much Does a Flat Roof Cost in the UK?

The cost of a new flat roof is a significant consideration. Prices can vary widely based on several factors, but providing a ballpark figure helps you budget effectively. The figures below are for supply and installation and are intended as a guide only. Always get a detailed, written quotation from your chosen tradesperson.

Costs are typically calculated per square metre (m²) and include stripping the old roof, any minor repairs to the deck, and installation of the new system.

• High-Performance Felt:£50 - £80 per m²
• EPDM Rubber Roofing:£70 - £100 per m²
• GRP Fibreglass Roofing:£80 - £120 per m²

For a typical single garage roof of around 15m², you might expect to pay between £900 and £1,800 depending on the material chosen.

Key Factors That Influence the Final Cost:

• Material Choice:As shown above, GRP is generally the most expensive option, while felt is the most budget-friendly.
• Roof Size and Complexity:A simple square roof is cheaper than one with multiple skylights, pipes, or awkward shapes.
• Condition of the Deck:If the timber joists or boards underneath are rotten, they will need replacing, which will add significantly to the labour and material costs.
-Insulation:Upgrading your roof insulation to meet current Building Regulations is often required and will increase the cost, but it will also save you money on your energy bills.
• Access:Difficult access, for example, over a conservatory or in a terraced property with no rear garden access, can increase labour costs.
• Location:Labour rates are typically higher in London and the South East compared to other parts of the UK.
• Waste Disposal:The cost of a skip to remove the old roofing materials and other rubbish must be factored in.

Questions to Ask Your Flat Roofing Professional

Finding a trustworthy tradesperson is crucial. Once you receive quotes through ServiceTasker, you should have a conversation with your preferred flat roof installers. Asking the right questions will help you distinguish a true professional from a "cowboy builder" and give you confidence in your choice.

• Are you fully insured?They must have Public Liability Insurance. Ask to see a copy of their certificate. This protects you and your property in case of an accident.
• Can you show me a portfolio of your work and provide references?A reputable flat roofing company will be proud of their work and happy to show you examples of similar jobs and let you speak to previous customers.
• What roofing system do you recommend for my property, and why?Their answer will reveal their expertise. They should be able to justify their choice based on your roof's size, use, and your budget, rather than just pushing the one system they know how to install.
• What guarantees do you provide?You should receive a guarantee for the workmanship (e.g., 10 years) and a separate manufacturer's warranty for the material (e.g., 20-25 years). Ask if the guarantee is insurance-backed, which provides cover even if the company ceases trading.
• Will you provide a detailed, written quotation?A professional quote should be a comprehensive document, not just a figure on the back of a card. It must break down the costs for labour, materials, insulation, waste disposal, and VAT.
• Who will be doing the work?Are they a direct employee or a subcontractor? Knowing who will be on your property each day is important for security and accountability.
• How will you protect my property and manage the waste?A good team will use dust sheets and boards to protect your home and garden, and will have a clear plan for disposing of all rubbish, usually via a licensed waste carrier and a skip.
• What are your payment terms?Be wary of anyone asking for a large cash deposit or the full amount upfront. A standard arrangement is a small deposit for materials, with the balance paid upon satisfactory completion. For larger projects, stage payments linked to progress are common. A contract, like a JCT Homeowner Contract, is advisable for all parties.
