Of course, this doesn't answer: Dry Ridge System or Mortar? So we are hoping the below might support in understanding what a dry ridge system is and the reasons people are choosing dry fix products over mortar for most roofing projects. 

What is a dry ridge system?

When undertaking a roofing project, it is crucial to prioritize safety, ventilation, and preventing water ingress. A dry ridge system effectively addresses all of these critical factors, providing a sense of security.

Dry ridge systems utilize mechanical or dry-fixing methods, such as nails, screws, or clips, to secure roof ridge and hip tiles on the roof. This eliminates the need for mortar, saving on maintenance, installation time, and costs.

Additionally, dry ridge systems are designed to provide 5mm continuous ventilation along the roof ridge, helping to prevent condensation in the roof space and allowing compliance with BS 5250 guidelines for managing moisture in buildings, while also protecting against rainwater infiltration.

How does the Dry Ridge System Work?

Dry ridge systems utilise screws and clamps to fix each ridge tile in place, with waterproof unions beneath the screws to divert water. One of the most popular dry ridge systems is the roll-out, which provides ventilation and waterproof protection, such as the Manthorpe Roll Out Dry Ridge Kit

In contrast to the mortar-based ridge system, the dry system offers numerous advantages. It is quickly and simply installed, requires minimal maintenance, is sturdier in bad weather and stronger winds, waterproof, and allows for roof flexibility. Plus, ventilation is enabled as the roll-out system prevents moisture build-up and potential structural damage.

Why choose dry fix & dry ridge systems instead of traditional mortar?

While mortar has long been used in roofing applications, the material has its downsides and dry ridge systems provide a modern, popular solution to these issues.

1. Mortar Cracks Over TimeThe roofing mortar used on your house may deteriorate and develop cracks over time, causing maintenance concerns for you as a homeowner, safety concerns for the roofers who will have to fix it, and the risk of falling debris and dislodged ridge tiles. Keep in mind that some roofing contractors may only provide a two-year guarantee for their mortar work.

Dry Fix Solution: Dry ridge systems are designed to withstand extreme weather conditions. Being mechanically fixed, they are very secure and, if installed to the manufacturer’s instructions, the risk of failure is very low. Majority of dry ridge systems have 10-15 years manufacturer guarantee

2. Mortar Requires Specific Conditions to CureBe aware that curing mortar can be slower in wet or cold conditions, potentially leading to frost damage and staining if not properly dried. 

Dry Fix Solution: Because dry ridge systems don’t need to dry or cure, they are quick to install & can be installed in any weather, rain or shine.

3. Mortar is difficult to transport/install: Mortar is heavy to transport and can be messy. For example, roofers carrying buckets of heavy mortar increases the risk of manual handling injuries, slips and falls and ultimately takes more time & skill than dry fix products.

Dry Fix Solution: Dry ridge systems are lightweight & easy to move. Installation is faster, safer and more manageable, saving time and money on your roofing project.

4. Mortar Requires Specialist Skill: Mortar requires specialist hand skills which can take years to perfect.

Dry Fix Alternative: Dry ridge systems are designed for simple installation. They require no specialist skills or tools. Majority of 'kits' come with everything you need for the installation.
