New roof guide

What goes into a new pitched roof?

A roof isn't just tiles — it's built up in layers, and the parts you can't see are the ones that make it last. Here's what's in every roof JK Roofing installs across Swindon and Wiltshire.

🧱Tiles & slates

The visible, weatherproof outer skin. The four main options — concrete tile, clay tile, natural slate and fibre-cement slate — are compared in detail below. Your choice affects look, lifespan and cost.

📏Roofing battens

The horizontal timber strips fixed across the rafters that the tiles hook onto. Quality matters here: we only fit BS 5534 graded, pressure-treated battens (the marked, coloured ones). Ungraded "rough sawn" batten is a common corner-cut — it can split, rot early and isn't accepted under tile manufacturers' warranties.

💧Breathable membrane (underlay)

The layer beneath the battens that stops any wind-driven rain reaching the timbers while letting moisture escape from the loft. We fit modern vapour-permeable (breathable) membranes instead of old bitumen felt, which traps moisture and leads to condensation and rot.

🔩Fixings, clips & nails

Since the 2014 update to British Standard BS 5534, tiles and slates must be mechanically fixed for wind resistance — not left to rely on their own weight. We nail and clip to the correct specification for your roof's exposure, so nothing lifts in a storm.

🏔️Dry ridge & dry verge

Ridge and edge tiles were traditionally bedded in sand-and-cement mortar, which cracks and lets tiles work loose within a few years. We fit mechanically-fixed, ventilated dry systems — far stronger, maintenance-free, and backed by a 15-year guarantee.

🌬️Ventilation

A roof has to breathe. Without airflow at the eaves and ridge, warm damp air condenses in the loft and rots the structure. Every roof we install includes the correct eaves and ridge ventilation for a dry, healthy loft space.

⚜️Lead & flashings

Code 4/5 lead (or a high-grade lead alternative) seals the joints around chimneys, valleys and where the roof meets a wall — the exact spots where most roof leaks actually begin.

Choosing your tiles

Concrete, clay or slate?

The four roof coverings we install most often, and what each is best suited to. Not sure which is right? We'll talk it through with you at your free survey.

Pitched roofing questions

Your questions, answered

What's the best type of roof tile?
There's no single "best" — it depends on your budget, property style and how long you want it to last. Concrete is the best value, clay is traditional and won't fade, and natural slate lasts longest and looks the most premium. We'll recommend the right option for your home and budget at the free survey.
Do I need a breathable membrane under my tiles?
We strongly recommend it. A breathable (vapour-permeable) membrane lets moisture escape from the loft while keeping wind-driven rain out. Older bitumen felt traps moisture and is a leading cause of condensation and rotten roof timbers. Every JK Roofing re-roof uses a modern breathable membrane.
Do my roof battens need replacing when I get a new roof?
Yes. On a full re-roof we always fit fresh BS 5534 graded, treated battens. Old battens are often brittle, undersized or non-compliant with current standards, and re-using them risks the whole roof. New battens are a standard part of our price — never an extra.
How long does a new roof last?
It depends on the covering: concrete tile 40–60 years, clay tile 60–100 years, and natural slate 80–100+ years. On top of the materials, JK Roofing backs the workmanship with a 10-year written guarantee and a 15-year guarantee on dry ridge and verge systems.
Do all the tiles have to be nailed or clipped?
Under BS 5534, tiles and slates must be mechanically fixed rather than relying on their weight. How many are nailed or clipped depends on your roof's pitch and wind exposure — perimeter and ridge tiles are always fixed. We calculate the correct fixing specification for your specific roof.
Is a dry ridge better than a mortar-bedded ridge?
Yes. A dry ridge system is mechanically screwed down and ventilated, so it won't crack, wash out or work loose like mortar does after a few winters. It's stronger, virtually maintenance-free, and we guarantee it for 15 years. We can also convert an existing cracked mortar ridge to dry without re-roofing.
Can you fit a new roof in winter?
Yes — we install roofs all year round. We sheet up and stage the work so your home is never left exposed, and only stop for genuinely unsafe conditions like high winds or ice. Autumn and winter are often quieter, so lead times can be shorter.

Flat roofing systems

EPDM, fibreglass or felt?

"Flat roof" covers several very different systems. Here's how the main ones compare, and which we'd recommend for your garage, extension or dormer.

Our recommendation

EPDM rubber

Typical lifespan30–50 years
Relative cost££
  • A single rubber sheet — seamless on most roofs
  • Stays flexible in heat and cold, won't crack
  • Manufacturer warranties up to 20–25 years
  • The best all-round choice for most flat roofs
Walk-on / hard-wearing

GRP fibreglass

Typical lifespan25–30 years
Relative cost£££
  • Seamless, rock-hard finish
  • Ideal for balconies and walk-on terraces
  • Crisp, neat trims and detailing
  • Needs dry, warm conditions to install
Budget option

Torch-on felt

Typical lifespan15–20 years
Relative cost£
  • Modern 3-layer high-performance felt
  • Lowest upfront cost
  • Proven, widely used system
  • Shorter life and more seams than EPDM/GRP
Complex shapes

Liquid waterproofing

Typical lifespan20–25 years
Relative cost££
  • Brushed/rolled on — totally seamless
  • Perfect for awkward shapes and pipework
  • Bonds over many existing surfaces
  • Great for roofs with lots of detail
Built to last

More than just the covering

Two things separate a flat roof that lasts decades from one that fails early — and they're under the surface.

🔥Warm roof construction

On a warm roof the insulation sits above the timber deck, keeping the structure warm and dry and preventing the hidden condensation that rots cold-roof decks from below. It's now the recommended approach under current Building Regulations, and what we build on new flat roofs and extensions.

📐Falls & drainage

A "flat" roof is never truly flat — it's built with a slight fall so rainwater runs off to the gutter or outlet instead of pooling. Standing water is the number-one killer of flat roofs. We design the correct fall into every roof, adding firrings or tapered insulation where needed.

Flat roofing questions

Your questions, answered

Which flat roof system is best?
For most homes we recommend EPDM rubber — it's seamless on most roofs, stays flexible in any weather and lasts 30–50 years. For a balcony or terrace you'll walk on regularly, GRP fibreglass is the tougher choice. Felt is the budget option. We'll advise the best fit at your free survey.
How long does an EPDM rubber roof last?
A well-installed EPDM roof typically lasts 30–50 years, with manufacturer membrane warranties of up to 20–25 years. On top of that, JK Roofing provides a 10-year written workmanship guarantee. Because it's a single flexible sheet, there are no seams to split as the temperature changes.
What's the difference between EPDM, GRP and felt?
EPDM is a flexible rubber sheet — best all-rounder, very long life. GRP (fibreglass) sets into a hard, seamless shell — ideal for walk-on roofs and balconies. Felt is a layered bitumen system — cheapest upfront but with more seams and a shorter life. We fit all three and match the system to the job.
What is a warm roof?
A warm roof has the insulation placed above the roof deck rather than between the joists below it. This keeps the deck warm and dry, prevents hidden condensation, and is the construction now recommended under Building Regulations. It's what we build on new flat roofs and single-storey extensions.
Do flat roofs need a slope?
Yes — every flat roof is built with a slight fall so water drains away rather than pooling. Standing water is the most common cause of flat-roof failure. Where the existing structure is dead level, we build the fall in with firring strips or tapered insulation.
Can you walk on a flat roof?
EPDM and GRP both take occasional foot traffic for maintenance. If you want a roof you'll use regularly — a balcony, terrace or roof you'll sit out on — we'll specify a proper walk-on GRP or a protected/paved finish designed for the load. Just tell us how you plan to use it.
Why does my old flat roof keep leaking?
Most older flat roofs are felt, which becomes brittle and cracks at the seams and upstands as it ages — and patch repairs rarely hold for long. Modern seamless systems like EPDM and GRP remove the weak points, which is why a full replacement usually works out cheaper than repeated repairs.
