Flue & Roof Penetration Weatherproofing in Kent
Pro Guard Roofing Specialists Ltd regularly undertakes roofing and weatherproofing work for companies installing new flue systems throughout Kent. Once a new flue has been installed through a pitched or flat roof, our experienced roofing team completes the surrounding roofing works to ensure the penetration is correctly finished and fully watertight.
About this service
When a flue is taken through a roof, the roof covering, underlay and weathering details around the penetration all need to be reinstated properly. A poorly finished flue penetration — gaps in the covering, inadequate flashing, or failed sealing — is a common and avoidable source of leaks, and one that is often missed when the flue installer is not also a roofing specialist.
We provide the roofing expertise to finish the job correctly: altering tiles or slates neatly around the flue, dressing and welding lead flashing and weathering, sealing the penetration, and carrying out any repairs to existing flue installations that are leaking or incorrectly finished. We have completed many of these jobs on behalf of specialist flue installation companies, leaving the surrounding roof properly weathered and watertight.
Typical problems we solve

- Failed sealing around stove and boiler flues

Our experienced roofing team carries out the work using quality materials, keeping the site clean and organised throughout.
We complete a final inspection, remove waste responsibly and confirm any applicable workmanship guarantee.
Guarantees
Qualifying works are backed by a Pro Guard workmanship guarantee, confirmed in writing with your quotation.
Frequently asked questions
Do you install the flue itself?
No. We do not install flues. We carry out the surrounding roofing and weatherproofing works — tile or slate alterations, lead flashing, sealing and repairs — once a flue has been installed through the roof by a specialist flue installer. We work alongside flue installation companies or attend after their installation is complete.
Can you repair a leaking flue penetration?
Yes. If a flue has been installed and the surrounding roof is leaking, we inspect the penetration, identify where water is entering, and carry out the necessary flashing, sealing or tile repairs to make it watertight.
Do you work for flue installation companies?
Yes. We regularly complete roofing and weatherproofing work on behalf of specialist flue installation companies across Kent. Flue installers and homeowners are both welcome to contact us.
Do you weatherproof flues on both pitched and flat roofs?
Yes. We complete weathering and flashing works around flue penetrations on pitched tiled or slated roofs and on flat roofing systems, using the appropriate detailing and materials for each roof type.
Can you inspect an existing flue flashing with a drone?
Yes. Where suitable, we use a drone roof survey to inspect existing flue flashings and the surrounding roof area safely, identifying visible defects without scaffolding for an initial view.
Which areas do you cover for flue weatherproofing?
We cover Maidstone, Tunbridge Wells, Sevenoaks, Tonbridge and the wider Kent area from our Maidstone and Tunbridge Wells bases. Call us on 01622 611 499 to discuss your requirements.
