Understanding UK Dry Roofing Systems: Verges, Ridges, and Valleys
In the UK, dry roofing systems have become increasingly popular due to their durability, ease of installation, and low maintenance requirements. Unlike traditional "wet" roofing methods that rely on mortar to secure components, dry systems use mechanical fixings, which provide greater flexibility and resistance to the UK's often harsh and variable weather conditions. Here’s a detailed look at how dry systems are applied to roof verges, ridges, and valleys.
What is a Dry Verge?
A dry verge system is used to protect and finish the edges of a pitched roof where the tiles meet the gable end wall. Traditionally, this area was secured with mortar, but dry verge systems use interlocking plastic or metal caps to cover and secure the tiles.
Benefits of Dry Verge Systems:
-
Durability: Dry verge systems are far more durable than mortar, which can crack and dislodge over time due to freeze-thaw cycles common in the UK.
-
Weather Resistance: They provide superior protection against wind uplift and driving rain, preventing water ingress and wind damage.
-
Maintenance-Free: Once installed, dry verge systems require minimal maintenance, unlike mortar which may need regular checking and repointing.
-
Aesthetic Appeal: They offer a neat, uniform appearance, with various colour options available to match the roof tiles.
-
Installation Process:
-
The dry verge caps are fitted to the edge of each tile, interlocking securely.
-
No mortar is needed, reducing installation time and mess.
-
End caps are added to complete the system, ensuring a tidy finish.
What is a Dry Ridge?
A dry ridge system secures the ridge tiles along the apex of a roof using a system of clips, screws, and brackets instead of traditional mortar.
​
Benefits of Dry Ridge Systems:
-
Long-Term Reliability: They are not prone to cracking or slipping, issues often seen with mortar-fixed ridges.
-
Ventilation: Many dry ridge systems are designed to allow for roof ventilation, helping to prevent condensation build-up in the roof space.
-
All-Weather Installation: Unlike mortar, which requires dry weather for installation, dry ridge systems can be installed in most weather conditions, ensuring year-round flexibility.
-
Wind Resistance: These systems are highly resistant to wind uplift, making them ideal for the UK’s windy and stormy conditions.
-
Installation Process:
-
A ventilated ridge roll is laid along the ridge line.
-
Ridge tiles are placed on top and secured with brackets that are screwed into the ridge batten.
-
The system is finished with end caps, ensuring a secure and weatherproof ridge.
What is a Dry Valley?
A valley is the area where two roof slopes meet, forming an internal angle. Dry valley systems are used to channel rainwater away from the roof efficiently, without the need for mortar.
Benefits of Dry Valley Systems:
-
Water Management: Dry valley systems are designed to channel water effectively, reducing the risk of leaks or water pooling.
-
Durability: Unlike mortar valleys, which can crack and erode over time, dry valleys are made from durable materials like GRP (Glass Reinforced Plastic) or metal, ensuring long-lasting performance.
-
Ease of Installation: They are easier and faster to install than traditional mortar valleys, as they don’t require precise mortar work.
-
Aesthetic Integration: Available in various colours and finishes, dry valley systems can be chosen to match the roof, offering a seamless look.
​
Installation Process:
-
A valley trough or channel is laid along the valley, typically over a breathable membrane.
-
Roof tiles are then cut to fit and laid over the trough, with the valley section left exposed to direct water flow.
-
Mechanical fixings secure the tiles in place, eliminating the need for mortar.
