Every roof has ridge tiles along its apex — and the method used to hold them in place makes a significant difference to how long they stay there. If you live in Basingstoke, particularly on one of the estates where mortar ridges have been re-bedded multiple times, this comparison matters.
Traditional mortar ridge involves bedding each ridge tile in a mix of sand and cement mortar. The mortar fills the gap between the ridge tile and the roof tiles beneath, creating a seal and holding the ridge in position by weight and adhesion. This technique has been standard for centuries and works well — initially.
Key Fact: Dry ridge systems tested to BS 8612:2018 must resist wind uplift forces of at least 2.7kN per metre, significantly exceeding the resistance provided by mortar bedding. Source: BS 8612:2018 — Dry-Fixed Ridge, Hip and Verge Systems
Mortar is rigid. Roof tiles expand and contract with temperature changes — every day. Over years, this constant micro-movement cracks the mortar. Water gets into the cracks, freezes in winter, and widens them further. Eventually the mortar loses adhesion entirely and the ridge tile sits loose on the apex, held in place only by gravity. The first strong gust removes it.
On Basingstoke's exposed estates — Brighton Hill, Kempshott, and any property facing the M3 corridor — this failure cycle can complete in 10–15 years. On sheltered estates it may take 20–25 years. Either way, it is a recurring cost and a recurring vulnerability.
Dry ridge replaces mortar with a mechanical system: each ridge tile is individually clipped to a metal rail fixed along the apex. A ventilated roll beneath the ridge tiles bridges the gap and provides weatherproofing. The clips grip the tile mechanically — no adhesion required. The system flexes with the roof rather than resisting movement.
Mortar ridge: lower initial cost, needs replacing every 10–25 years, offers no ventilation, vulnerable to storm uplift once mortar cracks. Dry ridge: higher initial cost, lasts the life of the roof (60+ years), provides passive ventilation to the roof space, resists storm uplift through mechanical fixing. Over the life of a roof, dry ridge is significantly cheaper and more reliable.

Roofing is one of the few trades where the customer usually cannot see the work being discussed. That asymmetry is why getting a second opinion on any significant quote is sensible — not because most roofers are dishonest, but because specifications genuinely vary and comparing them is the only way to know what you are buying.
When comparing quotes, look past the headline figure. Does each quote include scaffold? Are materials named by manufacturer or described vaguely as "quality tiles"? Is waste disposal included? Is there a written guarantee, and what does it actually cover? A quote that is £500 cheaper but omits scaffold and dry ridge is not cheaper at all.
Ask what happens if additional problems are found once work starts. A good answer describes a process: stop, photograph, discuss, agree cost, then continue. A vague answer suggests you may face unexpected charges. Ask what guarantee is provided and request it in writing. Ask whether the guarantee transfers if you sell — a transferable guarantee is a genuine selling point.
Finally, ask for references from recent local work. Any roofer confident in their standards will provide them readily, and following up two or three takes ten minutes that could save you thousands.
The National Federation of Roofing Contractors publishes technical guidance for homeowners covering material selection, standards compliance and choosing a contractor. Your local authority building control department can advise on when notification or approval is required. For conservation area and listed building work, the Basingstoke and Deane conservation officer is the definitive source on what materials will be acceptable.
For anything specific to your own roof, a professional inspection is worth more than any amount of general reading. Call 0125 624 2410 — advice costs nothing and there is no obligation to book work.

Four steps from first call to completed work. No call-out fee, no obligation, and a written quote before anything starts.
We inspect your Basingstoke ridge line from ladder access — checking mortar condition, tile security, and whether retrofit dry ridge or mortar re-bedding is the right approach.
Your quote specifies the dry ridge system, ridge length, any batten replacement needed, and total cost. We explain the long-term cost saving versus repeated mortar re-bedding.
Old mortar carefully removed. Ridge batten inspected and replaced if needed. Dry ridge rail fixed, ventilated roll laid, clips positioned, and ridge tiles re-seated and secured mechanically.
Every ridge tile mechanically fixed, ventilation confirmed, site cleaned. You receive a guarantee on a ridge system that lasts the life of the roof with zero maintenance.

Initially yes — dry ridge costs roughly £300–£500 more than mortar bedding for a semi-detached. But mortar needs replacing every 10–25 years, while dry ridge lasts the life of the roof. Over 60 years, dry ridge saves significantly.
Yes. Retrofit installation removes old mortar and fits the mechanical system to existing ridge tiles — typically a single day's work for a semi. No need to strip the main roof tiles.
Slightly — the ventilated roll is visible as a narrow strip beneath the ridge tiles. Most homeowners prefer the clean appearance. On new-builds and re-roofs, dry ridge is now the standard specification.
Some do because it is cheaper and faster for the installer. We recommend dry ridge as standard because it is better for the homeowner long-term — especially on Basingstoke's exposed estate rooflines where mortar failures are frequent.
Yes — the ventilated roll allows air to circulate through the ridge line, reducing condensation in the roof space. Mortar ridge blocks this airflow entirely, which can contribute to moisture problems in the loft.
Retrofit on a 3-bed semi: 4–6 hours. Larger detached properties: 6–10 hours. It is typically a single-day job with minimal disruption.
Brighton Hill, Kempshott and the southern estates facing the M3 corridor — where wind exposure causes mortar ridges to fail fastest. But any property that has had mortar ridges re-bedded more than once is a strong candidate for the upgrade.
