What Is Roof Pointing?

Roof pointing refers to the application of mortar to seal and secure tiles, ridges, verges, and other junctions on a pitched roof. While it is a traditional method used to weatherproof and stabilise roof components, its long-term reliability depends on the right materials, installation method, and property context.

Common Areas for Roof Pointing

We provide expert pointing and re-pointing services in the following areas:

Ridge Tiles – Securing ridge tiles against wind uplift
Hip Tiles – Mortar-bedding and sealing hips on gable or hipped roofs
Verge Tiles – Traditional mortar verges on gables and bargeboards
Chimney Stacks – Pointing around flashings and flaunchings
Valleys and Abutments – Mortar work to seal joints and transitions
Step Flashings – Lime mortar bedding where lead meets brickwork
Roofline Repairs – General repointing of defective areas prone to water ingress

Recommended Mortar Mixes for Roof Pointing

The choice of mortar mix depends on the age, material, and exposure of the roof. At Roof Dundee, we recommend the following:

For Most Modern Roofs:

Cement-Based Mortar (1:3 mix) – 1 part OPC (Ordinary Portland Cement) to 3 parts sharp sand

Optional: Add plasticiser to improve workability
Suitable for ridge tiles, hips, and verges on modern concrete tile roofs

For Traditional or Heritage Roofs:

Lime Mortar (NHL Mix) – 1 part Natural Hydraulic Lime (NHL 3.5) to 2.5–3 parts sharp or coarse sand

More breathable and sympathetic to older buildings
Ideal for use around chimneys, verges, and historic fabric

We always match our mortar to the property type and ensure proper curing conditions to avoid premature failure.

Compliance & Modern Alternatives – BS5534 Guidance

While mortar was historically used for nearly all roofing applications, BS5534:2014+A2:2018 (Code of Practice for Slating and Tiling) has made significant changes to recommended fixing practices.

Key points from BS5534:

Mortar bedding alone is no longer sufficient for securing ridge, hip, and verge tiles
Mechanical fixings or dry-fix systems are now required to comply with modern standards
Dry ridge, hip, and verge systems are mandatory on most new and replacement roofs
Buildings constructed post-1919 are typically suited to dry fix upgrades for longer-term durability

At Roof Dundee, we will always advise clients on the best course of action — whether to re-point using traditional methods or upgrade to a BS5534-compliant dry fix system for enhanced resilience and longevity.
