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.
General roofing advice only takes you so far, because the right answer depends heavily on what your roof is actually made of and when it went on. Basingstoke's housing splits into clear eras and each behaves differently.
The 1960s–70s overspill estates — Popley, Winklebury, South Ham, Oakridge, Buckskin and Black Dam — account for over a third of the town's stock and were roofed with concrete interlocking tiles on iron nail fixings. Those fixings are now 50 to 65 years old and failing across whole slopes at once, because they were all installed within a few years of each other. Anything you read about roof maintenance needs filtering through that: on these roofs the covering is often sound while the thing holding it on is not.
The 1980s–2000s estates — Chineham, Kempshott, Lychpit, Hatch Warren and Beggarwood — have decades of life left in the covering. What fails there is mortar and detailing: ridge and verge bedding, and flashing junctions at dormers and extensions where volume housebuilders used mastic instead of lead. Those are cheap fixes caught early and expensive ones left alone.
Old Basing and the older pockets around the Top of Town are different again. Handmade clay and natural slate last 80 to 150 years, so a century-old roof may have half its life remaining. Conservation area requirements mean matched materials and lime mortar, which changes both the method and the cost.
Roofing is one of the few trades where the customer cannot see the work being discussed, cannot watch it happen and cannot properly assess it afterwards. That asymmetry is why comparing quotes properly matters more here than almost anywhere else.
When you compare, look past the headline number. Does each quote include scaffold as its own line? 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 £500 cheaper that omits scaffold, new battens and dry ridge is not cheaper — it is a smaller job wearing the same name.
Ask what happens if additional problems appear once work starts. A good answer describes a process: stop, photograph, discuss, agree the cost, continue. A vague answer means you may face charges you did not sign up for.
The National Federation of Roofing Contractors publishes technical guidance for homeowners on material selection, standards compliance and choosing a contractor. Your local authority building control team can advise on when notification or approval is required. For conservation area and listed building work in Old Basing or Whitchurch, the Basingstoke and Deane Borough Council conservation officer is the definitive source on acceptable materials.
For anything specific to your own roof, an 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.
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.

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.
No call-out fees. No obligation. Just an honest quote from a local Basingstoke roofer who'll turn up when they say they will.
