A dry ridge system secures and weatherproofs the tiles at the top of a suitable pitched roof without relying on a mortar bed alone. When comparing systems, remember that ridge tiles can also be mechanically fixed as part of a mortar-bedded system.
So the choice isn't simply between dry fixing and tiles held by mortar alone. We consider your roof, ventilation, appearance and the available systems before explaining the work we recommend.
What Does a Dry Ridge System Do?
The ridge runs along the top where roof slopes meet. Hips are the sloping joins on some roof shapes. A dry-fix system secures and weatherproofs these areas, and some systems also provide ventilation.
We need to check that the system suits the pitch, tiles and shape of your roof, with sound support beneath it. A product described as universal still has fitting instructions and limits.
Ask us which system we propose and why it suits your roof. That tells you more than the words “dry ridge” alone.
Is Dry Ridge Legally Required?
Dry ridge isn't the only way to secure ridge tiles. Marley's February 2026 guidance explains the difference between dry fixing and mechanically secured mortar-bedded systems when discussing BS 5534. [1]
Marley also supplies a mortar-bedded security ridge kit, demonstrating that mortar bedding and mechanical restraint can be used together. [2]
Standards, building regulations, product instructions and heritage requirements each need considering. We'll explain the proposed roofing work and which checks are relevant. A traditional or protected roof may also need specialist advice on materials and appearance.
How the Two Approaches Compare
| Question | Dry-Fixed Proposal | Mortar-Bedded, Mechanically Fixed Proposal |
|---|---|---|
| How are tiles secured? | Using the system's fixings and supporting components | Using mechanical fixings as well as mortar bedding |
| How is rain kept out? | Through the system's fitted rolls, joints and accessories | Through suitable bedding and finished junctions |
| Is ventilation provided? | Some systems provide a defined ventilation path | It may need to be provided separately |
| What appearance is intended? | Depends on tiles, roll and accessories | Depends on the traditional or selected bedding detail |
| What needs maintenance? | Fixings, components and the surrounding roof still need checking | Mortar, fixings and the surrounding roof still need checking |
| How is suitability checked? | Against the product instructions and your roof's construction | Against the product instructions, roof construction and proposed details |
On small screens, scroll the table sideways to view every column.
Either approach needs to suit your roof and be fitted correctly. The name of the system alone won't tell you the quality of the finished work.
Will a Dry Ridge Improve Ventilation?
Some dry ridge systems include ventilation, but the amount and suitability are product-specific. Marley's RidgeFast information, for example, gives a 5 mm continuous ridge-ventilation equivalent and a stated product pitch range. Those are details of that system, not specifications for all dry ridge products. [3]
A ventilated ridge won't necessarily solve loft condensation. We need to consider the insulation, air movement and complete roof construction too. Please don't block other ventilation because a new ridge has been fitted.
Ask us whether the proposed system provides ventilation and how it fits the rest of your roof. Any interruptions at hips or other features need planning as well.
When Is Ridge Work Needed?
Loose ridge tiles, damaged mortar or a nearby leak are reasons to get the ridge checked. You don't need to change yours simply because a neighbour has had a different system fitted.
We look at the ridge tiles, fixings, supports and nearby covering as far as access allows. We'll explain what can stay and any repairs needed beneath the new components.
If components appear unstable, keep people away from the area below and seek appropriate advice. Do not climb onto the roof to test whether a tile moves. HSE's roof-work guidance applies to ridge repairs just as it does to larger reroofing jobs. [4]
Can Dry Ridge Be Added to an Existing Roof?
It may be possible. We need to check the ridge, supports and surrounding tiles first. Fitting dry ridge involves preparing and securing the system properly, not covering over damaged mortar.
We'll explain whether the existing ridge tiles can be reused, what needs removing and which support or connection work is included in the quote.
Replacing the ridge doesn't renew the whole roof. Your quote and guarantee should make clear which parts are covered by the work.
Traditional Roofs and Appearance
Ridge details can be an important part of an older building's appearance. Historic England recommends suitable repairs and keeping sound original materials where possible. A modern accessory won't suit every traditional roof. [5]
If your home is listed or has other relevant restrictions, check the requirements before changing the ridge. The proposed materials and appearance need considering for that particular property.
Ask us to explain how the finished ridge will look, including the tiles and visible accessories. That discussion belongs before the work starts.
Read the Whole Quotation
Check which ridge or hip sections are included, the system and tiles, preparation, supports, access and waste removal. We'll also explain any ventilation and how ends and joins will be finished.
Product warranties and workmanship guarantees cover different things. Ask us about the terms for your job. Neither means the roof can never suffer storm damage or needs no future checks.
For example: one quote may include new fixings and support while another mentions only visible caps. Both might say “dry ridge”, but the work isn't necessarily the same. Compare the preparation and construction included in each price.
The choosing-a-roofer checklist has more questions to help you compare experience, access arrangements and the work included.
After the Work Is Complete
Keep the product name, quote, invoice and guarantee, along with any photos provided of the work beneath the tiles. Ask what care and future checks the system needs.
A new ridge won't fix an unrelated leak at a chimney, valley or window. If a leak prompted the work, discuss how the result will be checked and tell us if the problem returns.
We offer dry ridge systems, dry verge work and pitched-roof repairs in Newcastle, Gateshead and Cramlington. Send the roof details and safe photographs through the quote page.
Frequently Asked Questions
Is Dry Ridge Compulsory on Every Roof?
No. Dry-fix systems and correctly designed mortar-bedded systems can both use mechanical fixings. Which approach suits your roof depends on its construction, the relevant guidance, product instructions and any heritage requirements.
Does Dry Ridge Stop All Loft Condensation?
No. Some systems provide ventilation, but insulation, air leakage and moisture in the loft matter too. Tell us about condensation so the cause can be considered before changing the ridge.
Can Existing Ridge Tiles Be Reused?
Sometimes, if they're sound and compatible with the chosen system. We'll explain what can be kept, along with any preparation and support work needed.
Is Dry Ridge Maintenance-Free?
It still needs suitable care and checks. Ask us about maintenance and the guarantee terms for the particular system, rather than relying on a maintenance-free claim.
Can a Dry Ridge Be Fitted Without Replacing the Whole Roof?
It may be possible if the existing roof and supports are suitable. We'll check the relevant areas and make clear what the ridge work includes; it doesn't mean the rest of the roof has been renewed.
Is Mortar Always a Bad Choice?
No. Mortar-bedded systems can include suitable mechanical fixings, and traditional roofs may need particular details. The proposal needs to suit the roof and any heritage requirements.
What Should a Ridge Quote Include?
The ridge sections, system, tiles, preparation, supports, access, waste and any ventilation work. Ask what's excluded and which product and workmanship guarantees apply.
