Why Choose Our Flat Roofing Services?
As Truro’s leading flat roofing specialists, we combine quality materials, expert workmanship, and outstanding customer service to deliver results that exceed expectations. We don’t cut corners, we don’t rush jobs, and we never compromise on quality—your flat roof is too important for anything less than our best work.
Felt Roofing Solutions
Traditional felt roofing remains a popular and cost-effective choice for flat roofs, particularly when installed correctly using quality materials and proven techniques.
Three-Layer Felt Systems
Our standard felt roofing installation uses a three-layer system that provides robust, reliable protection. We start with a base layer secured to the roof deck, add a middle layer for strength and stability, and finish with a mineral-surfaced cap sheet that resists UV damage and weathering.
High-Performance Felt
We use premium-grade roofing felt that outperforms cheaper alternatives. Our felt incorporates modern polymers that enhance flexibility, durability, and weather resistance, ensuring your roof performs reliably even in Cornwall’s challenging coastal climate.
Torch-On Felt Application
For superior adhesion and weather resistance, we use torch-on felt application methods. This technique creates a fully bonded, watertight membrane that eliminates the problems associated with older nailed felt systems.
Fibreglass (GRP) Roofing
Fibreglass roofing, also known as GRP (Glass Reinforced Plastic), represents the modern standard for flat roofing. This advanced system offers exceptional durability and performance that traditional materials simply cannot match.
Seamless, Watertight Protection
Unlike felt systems with multiple seams and joints, fibreglass creates a completely seamless membrane across your entire roof. This eliminates the weak points where leaks typically develop, providing superior long-term protection.
Exceptional Durability
Fibreglass roofs are incredibly tough. They resist cracking, splitting, and tearing, and they’re not affected by UV radiation, temperature extremes, or standing water. With proper installation, a fibreglass roof can last 30 years or more with minimal maintenance.
Quick Installation
Fibreglass roofing can typically be installed faster than traditional felt systems. The material cures quickly, meaning your roof is watertight and ready for use within hours rather than days.
Low Maintenance
Once installed, fibreglass roofs require very little maintenance. The smooth, non-porous surface doesn’t harbour moss or algae growth, and it’s easy to clean when necessary. This makes fibreglass an excellent long-term investment.
Our Flat Roofing Process
Quality flat roofing starts with proper preparation and follows proven installation procedures. Our systematic approach ensures consistently excellent results.
Thorough Inspection and Assessment
Every project begins with a detailed inspection of your existing roof structure. We check the deck condition, assess drainage, identify any underlying issues, and determine the most suitable roofing system for your situation.
Complete Preparation
Proper preparation is absolutely critical for flat roofing success. We ensure the roof deck is sound, dry, and properly supported. We install or upgrade edge trims, create appropriate falls for water drainage, and prepare the surface to receive the new roofing system.
Expert Installation
Our skilled roofers install your chosen roofing system using manufacturer-approved techniques and materials. Whether felt or fibreglass, we follow best practices precisely to ensure optimal performance and longevity.
Quality Finishing
We pay meticulous attention to details like upstands, outlets, and edge details—the areas where problems most commonly occur. Our thorough approach to finishing ensures every vulnerable point is properly protected.
Flat Roof Repairs
Not every flat roof problem requires complete replacement. Our repair specialists can often extend your roof’s life significantly through targeted repairs that address specific issues.
Leak Detection and Repair
Finding the source of flat roof leaks can be challenging, but our experienced team knows where to look. We locate leaks accurately and carry out effective repairs that stop water ingress and prevent further damage.
Blister and Split Repairs
Felt roofs can develop blisters and splits over time. We repair these issues properly, ensuring repairs blend with existing roofing and restore watertight integrity.
Patch Repairs
For localized damage, patch repairs offer a cost-effective solution. We match materials carefully and install patches that provide reliable, long-lasting protection.
Why Flat Roofs Need Specialist Attention
Flat roofs aren’t actually flat—they have a slight fall to allow water drainage. However, this minimal slope means water moves slowly and can pool if drainage isn’t perfect. This makes proper installation absolutely critical.
Poor flat roofing work leads to numerous problems including leaks, ponding water, premature deterioration, and structural damage. These issues are expensive to rectify and often require complete roof replacement.
Our professional approach eliminates these risks. We create proper falls, ensure effective drainage, use quality materials, and apply proven installation techniques that deliver reliable, long-term performance.

Frequently Asked Questions
Which is better—felt or fibreglass roofing?
Fibreglass (GRP) generally offers superior performance and longevity, lasting 25-30+ years compared to 10-20 years for felt. However, felt roofing costs less initially and remains a perfectly adequate choice for many applications. We’ll recommend the best option based on your budget, requirements, and the specific characteristics of your roof.
How long does flat roof installation take?
A typical domestic flat roof installation takes 1-3 days depending on size and complexity. Fibreglass roofs often cure within hours, while felt systems may need a day or two for proper adhesion. We’ll provide an accurate timeframe during your quotation and work efficiently to minimize disruption.
Can you install flat roofing in winter?
Yes, though weather conditions do affect scheduling. Fibreglass installation requires dry conditions and temperatures above 5°C for proper curing. Felt roofing is more weather-tolerant but still requires dry conditions. We monitor forecasts carefully and schedule work during suitable weather windows.
Why is my flat roof leaking?
Common causes include poor installation, inadequate drainage causing ponding water, splits or blisters in felt, failed seams, or damage to upstands and flashings. Our inspection will identify the specific cause and determine whether repair or replacement is the most cost-effective solution.
Do flat roofs need regular maintenance?
Yes, regular maintenance extends flat roof life significantly. We recommend annual inspections to check for debris accumulation, drainage issues, and early signs of wear. Keeping gutters clear and removing debris prevents many common problems. We offer maintenance services to keep your flat roof in optimal condition.
