Single Ply Roofing vs Traditional Felt – A Cost Breakdown

Single Ply Roofing vs Traditional Felt – A Cost Breakdown

Introduction

When it comes to choosing a flat roof, many homeowners and businesses in South Yorkshire think of felt first. It’s cheap upfront, widely available, and has been around for decades. But when you dig deeper, the numbers tell a different story. While single ply roofing may have a slightly higher initial cost, it outperforms felt by miles in durability, warranty, and long-term savings.

At Skyguard Flat Roofing LTD, we’ve replaced countless felt roofs with single ply PVC membranes. Time and again, the homeowners admit they wished they’d chosen single ply in the first place. Let’s break down the costs so you can make an informed decision.

Upfront Price Comparison

• Felt Roofing: On average, felt can cost between £40–£60 per m² installed.
• Single Ply Roofing: Expect around £70–£100 per m² installed, depending on the system (IKO Armourplan, Sarnafil, etc.).

At first glance, felt seems like a bargain. But here’s the hidden truth: the life expectancy of felt is 5–10 years, while single ply lasts 40+ years with a 20-year warranty.

Hidden Costs of Felt Roofing

1. Frequent Repairs – cracks, bubbles, and lifting seams mean ongoing call-outs.
2. Early Replacement – many felt roofs fail within a decade, forcing homeowners to pay twice.
3. Property Damage – leaks can damage plaster, electrics, and interiors.

Long-Term Value of Single Ply

1. Warranty Protection – 20 years of peace of mind, transferable if you sell.
2. Lower Maintenance – smooth finish sheds water, no pooling or cracks.
3. Energy Efficiency – especially with warm roof build-ups.

Local Example – Barnsley Garage Roof

A homeowner in Barnsley had a felt garage roof that cost £1,200 to install. Within 7 years, they had spent another £1,500 on repairs and patching. We replaced it with a single ply system at £2,200 — guaranteed for 20 years. Over its lifespan, single ply saved them more than £5,000.

Conclusion

The question isn’t whether single ply is more expensive upfront — it’s whether you want to pay twice. With a lifespan of four decades, low maintenance, and strong warranties, single ply roofing is the clear winner.
