B2B Trade Supply. Ireland.
Aluminium Lead Replacement Flashing Systems
We manufacture lead alternative aluminium flashings in Ireland. Our lightweight pressings provide a modern, non toxic weatherproofing solution for valleys and chimneys.
Silicone is not a building material. Precision over speed.
Project Profile
Dublin Manufacturing Excellence.
We fabricate B2B components at our Dublin facility. Standard 2mm marine-grade alloy ensures durability in coastal environments. Qualicoat powder coating provides RAL-matched weather protection. Fast nationwide delivery in 3 to 5 working days. All measurements verified through the app are built to a 0mm fabrication tolerance.

Modern Non Toxic Alternatives
Lead replacement flashings are increasingly specified in Ireland due to toxicity concerns and scrap metal theft risks. Our aluminium flashing systems are fabricated from two millimetre thickness raw alloy, providing a lightweight yet highly durable alternative. The sheets are pressed to shape and finished in low gloss colors to match traditional slate roofs.

Durable Chimney and Valley Pressings
We fold chimney aprons, back gutters, and step details to your drawing dimensions. The metal does not leach toxic chemicals into rainwater collection systems. Our workshop prefabricates mitered corner pieces to guarantee weather integrity on site.

Ecological and Environmental Compliance
Aluminium is one hundred percent recyclable and environmentally inert. Rainwater run-off from aluminium flashings is completely safe for groundwater systems. This makes aluminium an ideal choice for sustainable commercial projects aiming for LEED or BREEAM environmental ratings.

Alloy Purity and Mechanical Properties
We use 1050A grade aluminium sheets to press our lead alternative flashings. This alloy has ninety-nine point five percent chemical purity, which gives it high ductility. It can be folded cleanly without structural micro cracking along the bend lines, maintaining durability.

Qualicoat Surface Finishes
Our alternative flashings are powder coated to Qualicoat standards to ensure long-term color stability. We use a low-gloss matte finish that mimics the grey look of traditional leadwork, satisfying planners on heritage and sensitive projects.
Technical FAQ
Frequently Asked Questions
Why specify aluminium instead of lead for roof flashings?
Aluminium is non-toxic, lightweight, cost-effective, and does not pose a theft risk compared to traditional heavy lead sheet.
What thickness of aluminium is used for lead replacement?
We use one point five millimetre or two millimetre aluminium depending on the required profile rigidity.
Can these flashings be painted to look like lead?
Yes, we powder coat the profiles in a dark grey finish that mimics the look of traditional leadwork.
What is the lifespan of aluminium roof flashings?
Our marine grade alloy systems are engineered to last over thirty years with minimal maintenance.
Is lead alternative flashing easier to install?
Yes, because it is much lighter than lead, making it easier to handle on scaffolding. The pre welded corners save substantial site labor.
Does rainwater runoff from aluminium damage zinc or copper gutters?
Aluminium is chemically compatible with most standard rainwater systems. We recommend using EPDM gaskets to isolate contact points between dissimilar metals to prevent galvanic corrosion.
