Precision
Lead Engineering
The ultimate defense at your property's most vulnerable junctions. Mastercraft chimney flashing, valley linings, and bespoke lead installations executed to exacting architectural standards.
The Junctions of Failure
A roof rarely fails in the center of a tiled expanse. The vast majority of catastrophic water ingress occurs at the structural junctions: where the roof meets a chimney, abuts a wall, or converges into a valley.
Modern contractors frequently compromise these critical areas by using cheap mastic sealants, flashband tape, or improperly installed, thin-gauge lead that splits under thermal expansion. Vertex Roofing Group does not compromise.
We employ dedicated leadwork specialists. We utilize only premium milled or cast lead, fabricated and dressed by hand to accommodate the natural movement of your property. Our installations are not just weatherproof; they are permanent architectural enhancements designed to last over a century.
Disciplines
Specialist Fabrication
Chimney Flashings
Chimney stacks endure immense weather exposure. We completely reconstruct failing perimeter defenses, installing precision-cut lead soakers, front aprons, step flashings, and back gutters. The lead is chased deep into the masonry joints and secured with structural pointing, guaranteeing an impenetrable seal.
Valley Linings
Where two roof pitches meet, water concentration is highest. Pre-formed GRP valleys often crack under structural shift. We fabricate heavy-duty Code 5 or Code 6 lead valleys, dressed flawlessly onto timber valley boards. This traditional method ensures total watertight integrity capable of handling torrential North West downpours.
Dormers & Abutments
We execute complex bespoke leadwork for dormer windows, parapet walls, and single-story abutments. From fully lead-clad dormer cheeks to intricate saddle details, our leadworkers employ traditional bossing and welding techniques to create continuous, seamless metal architecture.
The Execution Protocol
Why commercial entities and discerning homeowners demand our mastercraft leadwork.
LSA Compliance
Every installation we execute strictly adheres to the guidelines set forth by the Lead Sheet Association. This governs the correct sizing, overlap, and fixing methods required to prevent thermal restriction and subsequent fatigue cracking.
Zero Sealant Reliance
Leadwork should be waterproof by design, not by chemistry. We rely on the physical overlapping and precise dressing of the metal to repel water. Sealants degrade in years; properly fabricated lead lasts lifetimes.
Correct Code Application
Many contractors cut costs by using thin Code 3 lead for load-bearing areas. We utilize heavy-gauge Code 4, 5, and 6 lead precisely where dictated by structural stress, ensuring maximum durability against extreme weather.
Specialist Craftsmen
Leadwork is an entirely separate discipline from standard roofing. We deploy dedicated craftsmen who have spent decades perfecting the art of lead welding, bossing, and dressing.
Leadwork FAQ
Why is lead used on roofs instead of modern sealants?
Lead is fundamentally superior to temporary mastics and sealants. When dressed correctly by a master craftsman, lead accommodates thermal expansion and contraction without cracking. It provides a permanent, impermeable barrier at the most vulnerable junctions of a roof, lasting well over a century.
What causes lead flashing to fail?
Failure is almost exclusively due to poor installation. Incorrectly sized pieces, restricting thermal movement, or using substandard, thin lead (Code 3 where Code 4 or 5 is required) leads to splitting. Vertex exclusively employs specialized leadworkers who strictly adhere to Lead Sheet Association (LSA) guidelines.
Do you repair cracked leadwork?
We do not 'patch' cracked lead with sealants or flashband tape. These are temporary masking tactics. We execute complete removals of the failing sections and fabricate entirely new, correctly dressed lead systems to ensure structural integrity.
What is the difference between 'Code 4' and 'Code 5' lead?
The 'Code' refers to the thickness and weight of the lead sheet. Code 4 is typically used for standard flashings and soakers. Code 5 is thicker and used for valleys, parapets, and complex bespoke fabrications where greater durability and resistance to thermal fatigue are required.
