🏡 Flat Roofing for Extensions in Sheffield – What You Need to Know
If you’re planning a home extension in Sheffield, one of the biggest decisions you’ll make is the roof. Should you go for felt, rubber, GRP, or something more modern?
At Skyguard Flat Roofing LTD, we’ve helped families across Ecclesfield, Handsworth, Hillsborough and beyond build extensions that not only look great but last for decades. Here’s what you need to know.
🏗️ Why Single Ply is Perfect for Extensions
Unlike old felt roofs, single ply membranes are:
- Seamless & Waterproof – welded joints stop leaks before they start.
- Flexible & Lightweight – perfect for new extensions that often have lanterns or skylights.
- Modern Finish – a sleek look that blends well with brickwork and uPVC.
- Long-Lasting – 40+ year lifespan with a 20-year warranty from Skyguard.
Extensions are a big investment. Single ply ensures the roof is one less thing you’ll need to worry about.
🌞 Can Single Ply Handle Roof Lanterns & Skylights?
Yes! Sheffield homeowners love adding natural light to extensions. Single ply works brilliantly with:
- ✅ Roof lanterns
- ✅ Skylights
- ✅ Bi-fold door extensions
Our membranes are welded neatly around upstands, meaning no weak spots for water to creep in.
❓ FAQs About Extension Roofing in Sheffield
Q: How much does an extension roof cost in Sheffield? It depends on the size and features (skylights/lanterns). You can get an instant idea with our free online estimator.
Q: Can you replace my old extension roof without removing it? In some cases, yes — single ply can overlay existing systems if the base is sound.
Q: Do you work across all Sheffield areas? Absolutely. We cover Ecclesfield, Handsworth, Hillsborough, Darnall, Gleadless, Chapeltown and all surrounding suburbs.
Q: How long will installation take? Most extension roofs are completed in 1–3 days, depending on size and features.
🛠️ Why Felt & GRP Don’t Compare
- Felt: cheap, but cracks within 10–15 years — not worth it on a brand-new extension.
- GRP/Fibreglass: looks good, but brittle in frost and not ideal for bigger spans.
- Single Ply: flexible, seamless, UV and frost resistant — perfect for Sheffield’s changing weather.
