At Metal Profiles Ltd we supply a wide range of aluminium components that finish and protect flat roofs, parapets, junctions and green roof edges. From clean roof edge drip trim and drip edge trim through to roof flashing, termination bars, valley sections, soakers and pipe sleeves, these details play a vital role in keeping water away from the building.
Whether you’re a roofer working on a refurbishment in Essex, an architect specifying a new extension, or a homeowner dealing with leaking roof edges, getting these details right makes a big difference.
All our products are fabricated here in Chelmsford, Essex. We can supply them in mill finish or polyester powder coated in any RAL colour to match your guttering, copings or facade. Based at Highlands Farm, Rettendon Common, CM3 8EB, we support projects across Chelmsford, Essex and the whole of the UK.

What These Roof Accessories Include
Our roof accessories range covers the practical metal details that finish and protect roof edges, penetrations and changes in level. Current sub-categories include Roof Accessories and Living Roof Accessories.
Key products include:
- Aluminium drip trim and roof edge drip trim (3m lengths)
- Internal and external corner pieces for drip trim
- Aluminium roof flashing (3000mm)
- Aluminium termination bar (2500mm)
- Aluminium valley flashing (2.4m)
- Aluminium roof soakers (supplied in packs of 25)
- Parapet and green roof inspection chambers
- Aluminium and lead roof penetration pipe sleeves
These items are designed to work together with our aluminium copings, fascia & soffit, box gutters and downpipes.
Common Uses on UK Projects
You will most often see these accessories on:
- Flat roof perimeters and parapet walls
- Roof extensions and loft conversions
- Junctions between new and existing roofs
- Green roof and living roof edge retention
- Areas where pipework or services penetrate the roof
- Valleys between pitched or mono-pitch roofs
In the wet Essex climate, getting the drip edge, flashing and termination details right helps prevent water tracking behind membranes or into the building fabric.
Why Aluminium Works Well for Roof Details
Aluminium is lightweight, does not rust, and can be powder coated to any RAL or BS colour. It is easy to fabricate into precise profiles, which is why it is widely used for bespoke roof trims, metal roof flashing and soakers across the UK.
We fabricate rather than simply stock imported items, so we can adjust lengths, folds, fixing holes or profiles when standard sizes do not quite fit your detail.
Standard Products vs Bespoke Fabrication
Many of the items shown are held as standard profiles in popular sizes. However, a large part of our work involves making adjustments for specific projects different leg lengths on drip trim, deeper valley sections, special corner angles, or matching an existing roof pitch.
If the product you need is not listed, send us a sketch or dimensioned drawing. We can usually manufacture a practical solution at sensible cost.
What to Measure Before Ordering
To get an accurate quote quickly, please have ready:
- Length of straight runs required
- Internal and external corner angles (if not 90°)
- Roof build-up thickness (especially important for termination bars and pipe sleeves)
- Preferred colour / RAL reference
- Any fixing restrictions or membrane type
Clear information at the estimating stage reduces the chance of changes later.
How These Accessories Connect With Other Systems
Roof edge drip trim and termination bars often work directly with our aluminium fascia and soffit and aluminium box gutter systems.
Aluminium roof flashing and roof soakers are regularly specified alongside aluminium wall copings and parapet details.
Pipe sleeves and inspection chambers are useful when combining our aluminium guttering in Chelmsford and Essex with flat roof refurbishments.
Common Ordering Mistakes to Avoid
- Ordering drip trim without confirming internal and external corners
- Choosing termination bar length without allowing for overlaps
- Forgetting to specify the exact roof build-up height for pipe sleeves
- Ordering mill finish when the rest of the roofline is coloured
Taking time on the specification stage saves cost and avoids site cutting.
When to Request an Estimate
If your project involves unusual roof junctions, green roof edge retention, stepped parapets, or you simply want everything to match in one colour, it is worth sending your drawings early. Our estimating team, based in Chelmsford, can price standard items and any bespoke fabrication together.
We supply contractors, roofers, architects and builders across the UK from our base in Essex.
