If you’ve searched “reroofing,” chances are you’re dealing with one of two things: an old, leaking conservatory roof that’s cold in winter and unbearable in summer, or a garage, extension or outbuilding with a tired flat roof that’s overdue a replacement. This guide covers what reroofing actually involves, realistic costs for 2026, and what to expect at each stage, for homeowners across Cheshire, Staffordshire and Shropshire.

What Does “Reroofing” Actually Mean?

Reroofing generally falls into two categories, and it’s worth knowing which one applies to your project before you start getting quotes.

Conservatory roof replacement means removing your existing conservatory roof, usually glass or polycarbonate, and replacing it with either a modern high-performance glass roof or a warm, insulated tiled roof. This is one of the most common home improvement projects in the UK right now, since it transforms an unusable seasonal space into a room you can enjoy all year round.

Flat roof replacement applies to garages, extensions and outbuildings with a flat roof covering, typically felt, EPDM rubber, or an older bitumen system. Reroofing here means stripping back to the deck and fitting a new, watertight membrane.

At Storm Right, we handle both. Our surveyor will always assess which category your project falls into during a free, no-obligation visit, and there’s no cost or obligation to find out.

Signs You Need a New Roof

• Your conservatory is too cold in winter and too hot in summer
• Damp patches, discolouration or a musty smell inside
• Condensation running down the inside of glass or polycarbonate panels
• Cracking, bubbling or “alligatoring” on a flat roof surface
• Water pooling on a flat roof rather than draining away
• Visible daylight or draughts around roof joints and seals

How Much Does Reroofing Cost in 2026?

Costs vary considerably depending on size, material and the condition of the existing structure, but here’s a realistic guide based on current UK market rates for 2026:

Conservatory roof replacement:

• Polycarbonate to polycarbonate: from around £2,500, the cheapest option, though it won’t resolve temperature or condensation issues
• Modern glass roof: typically £4,500 to £9,000, depending on size and glazing specification
• Warm, insulated tiled roof: typically £6,000 to £12,000, the most popular upgrade since it turns the space into a genuine year-round room

Flat roof replacement (garage, extension or outbuilding):

• Cost depends heavily on the size of the roof and the material used, EPDM rubber roofing tends to offer the best long-term value thanks to its durability and minimal maintenance

These figures are a general guide only, not a quote. Every property is different, which is why we always provide a free, written quote after visiting your home, so you know exactly what to expect with no hidden costs.

What Affects the Price?

• Size and shape of the conservatory or roof, a simple lean-to is cheaper than an ornate Victorian or P-shaped conservatory with multiple facets
• Material chosen, polycarbonate, glass, or a solid tiled system each carry different costs
• Condition of the existing frame, whether it can take a new roof as is, or needs reinforcing first
• Access to the property and whether scaffolding is required

Do I Need Planning Permission?

In most cases, no, a like-for-like reroofing project doesn’t require planning permission. However, some projects may still need building regulations approval, particularly where a warm, insulated tiled roof is being fitted in place of glass or polycarbonate, since this can change the structural loading and thermal performance of the space. Our surveyor will advise on this specifically for your property during your free visit, and this isn’t legal advice, just general guidance, so always confirm your specific requirements before work begins.

How Long Does Reroofing Take?

Most conservatory roof replacements are completed within one to two days for a straightforward glass-to-glass or polycarbonate swap. A full warm tiled roof conversion, which involves more structural work, typically takes a few days longer. Flat roof replacements on garages and extensions are usually completed within a day or two, depending on size. We’ll give you a clear timeframe as part of your written quote.

Frequently Asked Questions

What’s the difference between reroofing and a full conservatory rebuild?
Reroofing keeps your existing conservatory frame and structure in place, only the roof itself is replaced. A full rebuild is a much bigger, more expensive project involving the whole structure. For most homeowners with a sound frame, reroofing is the far more cost-effective option.

Is a tiled roof better than a glass roof for a conservatory?
It depends on your priorities. A warm tiled roof offers the best insulation and turns the space into a genuine year-round room, while a modern glass roof keeps more natural light while still improving on an old, draughty original roof. Our surveyor can talk through samples of both during your free visit.

How much does reroofing cost on average?
For a conservatory, costs typically range from around £2,500 for a basic polycarbonate swap up to £12,000 for a full warm tiled roof conversion, depending on size and specification. We provide a free, written quote after visiting your home so you know the exact cost for your project.

Can you repair my roof instead of replacing it?
Sometimes, yes. If the damage is limited, a repair may be enough to resolve the issue. Our surveyor can assess this and advise honestly on whether a repair or full reroof is the better option for your budget.
