Why Aluminium Roof Trims Outperform Lead and uPVC

Lead roof trims are expensive, heavy, and increasingly restricted due to environmental regulations. uPVC trims crack, fade, and cannot be colour matched accurately. Aluminium trims solve both problems — lightweight, durable, and available in any RAL colour.

Every roof edge is different. That is why Cills.ie manufactures roof trims to your exact dimensions, ensuring a precise fit that off-the-shelf profiles cannot achieve. No site cutting, no waste, no compromise on weather protection.

Types of Aluminium Roof Trims

We manufacture the full range of roof edge trims. Each is folded to your specification and powder coated to match your building.

Verge Trims

Protect the gable edge of pitched roofs. Prevents wind uplift of slates and tiles while providing a clean, finished appearance to the roof edge.

Drip Trims

Fitted at the eaves to shed water clear of the fascia and into the gutter. Essential for flat roofs and warm roof build-ups where the membrane terminates at the edge.

Ridge Cappings

Aluminium ridge cappings cover the apex of pitched roofs. Lighter than lead, more durable than mortar bedding, and available in colours to match your roof or walls.

Eaves Trims

Support the first course of slates or tiles and direct water into the gutter. Designed to integrate with ventilated eaves details for roof space airflow.

Barge Board Trims

Cover and protect timber barge boards on gable ends. Encapsulate the timber to prevent rot and eliminate the need for repainting.

Valley Trims

Line the valley where two roof slopes meet. Aluminium valley trims channel water efficiently and resist the corrosion that affects lead and zinc alternatives.

What Are Roof Trims and Why They Matter

Roof trims are the protective and decorative metal profiles that finish every exposed edge of a roof. Without them, water ingress, wind uplift, and timber rot become real risks that cost far more than the trim itself.

Every roof has edges. The gable ends. The eaves. The ridge. The valleys. Each of these edges needs a profiled trim to shed water, block wind, and give the roofline a clean finished appearance.

Traditionally, Irish roofs used lead or mortar for these details. Lead is heavy, expensive, and increasingly restricted. Mortar cracks and fails within years. Aluminium roof trims solve both problems. They are lightweight, durable, and available in any RAL colour to match the rest of the building envelope.

Prevent water ingress at roof edges and junctions
Stop wind uplift on slates and tiles at gable edges
Protect timber barge boards and fascia from rot
Eliminate the need for repainting or mortar repair

Materials and Finish Options

Every roof trim we manufacture is cut from marine-grade aluminium sheet and finished with a QUALICOAT-certified polyester powder coat. This is the same specification used on our window sills and flashings, so your entire building envelope matches.

Standard Polyester Powder Coat

60 to 80 microns thickness. Suitable for most inland and sheltered coastal projects. 30+ year coating warranty. Full RAL Classic range available.

Marine Grade Finish

80 to 120 microns thickness. Recommended for coastal properties exposed to salt spray and high wind. Extended warranty and enhanced corrosion resistance.

Full RAL Colour Matching

Match your roof trims to your window sills, cappings, flashings, and doors. Over 200 RAL Classic colours. Consistent finish across every aluminium element on the building.

Suitable For Every Project Type

Whether you are building a one-off house, developing a housing estate, or retrofitting a commercial building, our roof trims are manufactured to your exact specification.

Residential New Build

Single houses, housing estates, and apartment blocks. Coordinated roofline packages that match window sills, cappings, and flashings. Consistent colour and finish across the entire development.

Retrofit and Extension

Upgrade existing rooflines without the weight of lead. Replace cracked mortar ridge cappings with powder coated aluminium. Match new extensions to existing building colours.

Commercial and Industrial

Office buildings, warehouses, and agricultural structures. Large quantity orders with consistent colour batching. Fast turnaround to keep construction programmes on track.

Warm Roof and EWI Projects

External wall insulation and warm roof build-ups require specific drip and termination trims. Our profiles integrate with insulation systems to maintain thermal performance and weather tightness.

Frequently Asked Questions

Everything you need to know about ordering aluminium roof trims in Ireland.

What is the difference between a verge trim and a drip trim?

A verge trim runs along the gable edge of a pitched roof. It protects the roofline and prevents wind uplift of slates and tiles. A drip trim is fitted at the eaves or roof edge to direct water clear of the fascia and into the gutter. Both are essential for weatherproofing but serve different positions on the roof.

Can roof trims be colour matched to windows and doors?

Yes. Every roof trim is powder coated in your chosen RAL Classic colour. This means you can match your roof trims exactly to your window sills, cappings, flashings, doors, and curtain walling. Over 200 RAL colours are available with consistent finish across all products.

How long do aluminium roof trims last?

Aluminium roof trims last the lifetime of the building. The marine-grade aluminium substrate does not rot, crack, or corrode. The QUALICOAT polyester powder coating carries a 30+ year warranty for standard finishes and extended warranty for marine-grade specifications.

Do you supply fixing brackets and screws?

We manufacture the trim profiles to your exact dimensions. Fixing brackets, secret fix clips, and colour-matched screws can be supplied on request. Our team can advise on the best fixing method for your roof type during the order process.

What is the turnaround time for custom roof trims?

Manufacture takes 3 to 5 working days from order confirmation. Delivery is tracked nationwide to all 32 counties. For large commercial orders or coordinated packages including sills and cappings, we can schedule production to align with your site programme.

Are aluminium roof trims better than lead?

Aluminium roof trims are lighter, cheaper, and easier to install than lead. They do not suffer from thermal expansion cracking or theft risk. They are not subject to the environmental restrictions that increasingly affect lead use in construction. And they are available in colours. Lead cannot match that.
