Weatherproof and secure roof penetrations
A roof penetration is a hole that is made in a roof in order to install a service, piece of equipment, pipework, ducting or conduits.
Often, roof penetrations are used in conjunction with building services, such as:
- HVAC equipment
- Extraction ducting
- Rooflights and roof windows
- Access hatches
- Data and telecom cables
- Solar panels
- Chimneys and flues
- Manufacturing plant
Creating a roof penetration in an existing roof requires cutting through the building envelope and ensuring the hole is fully weatherproofed against the weather and moisture ingress. Inadequate weatherproofing can lead to damage and instability. That’s why careful planning and detailing are required, ensuring the roof penetration and equipment are safely installed and well-sealed.
At Jones Weatherproofing, we offer roof penetration weatherproofing for all types of commercial and industrial roofs. Whether the roof is flat, pitched or curved, or made of metal, concrete, GRP or felt, our specialist weatherproofing system will provide a durable and reliable seal that prevents leaks and thermal breaks.

Weatherproofing flat roof penetrations
The benefit of roof penetrations is that they allow equipment to be installed on the often-underutilised roof area, thereby freeing up valuable indoor space. Due to concerns about weatherproofing and structural integrity, it is a common misconception that the best way to deal with roof penetrations is to avoid them altogether. However, there is no need to design out roof penetrations if they are designed well and installed with care.
The key to a successful roof penetration installation is to get expert advice early on. The team at Jones Weatherproofing can provide detailed drawings and advice on all aspects of the installation – including where to place building penetrations and upstands to ensure structural support, protection of the building envelope, prevention of thermal breaks, and to create a weatherproofed finish.
We will also work with you to ensure that the result meets all regulatory requirements, for example, those set out in British Standards such as BS 6229:2003, as well as national building regulations.
