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.
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.
Concrete tile
- The most popular and affordable choice
- Huge range of colours and profiles
- Heavy — needs a sound roof structure
- Colour can soften slightly over decades
Clay tile
- Naturally colour-fast — won't fade
- Classic look for period & rural homes
- Very low maintenance
- Dearer than concrete
Natural slate
- The longest-lasting roof you can buy
- Timeless, premium appearance
- Can add value to the property
- Highest material and labour cost
Fibre-cement slate
- The slate look for less
- Lighter than natural slate or tile
- Good where the structure can't take heavy tile
- Shorter lifespan than the real thing
