{"product_id":"grp-roof-edge-trim-perimeter-packs","title":"GRP Roof Edge Trim Perimeter Packs – 9 Profiles, 3m Lengths, 12m \u0026amp; 24m Packs","description":"\u003cp\u003eA flat roof rarely fails in the middle. It fails at the edge — where water runs off, where wind gets underneath, and where a badly finished perimeter lets the covering lift or the fascia rot. A moulded GRP edge trim solves all three at once: it gives the waterproofing a solid arm to bond onto, throws water clear of the fascia, and finishes the roof with a straight, crisp line that lasts as long as the roof does.\u003c\/p\u003e\n\n\u003cp\u003eThese are glass-reinforced polyester (GRP) trims in 3m lengths, sold here as perimeter packs rather than single pieces, because a roof edge is a run — not one length. Nine profiles cover face heights from a slim 40mm up to a deep 200mm, with a choice of flat or angled fixing arm, in black, grey or white throughout the range.\u003c\/p\u003e\n\n\u003ch3\u003eKey benefits\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eMoulded GRP — won't rust, rot, corrode or need painting, unlike steel or timber edge details\u003c\/li\u003e\n\u003cli\u003eNine face heights (40mm to 200mm) so the trim suits the actual depth of your roof build-up and fascia\u003c\/li\u003e\n\u003cli\u003eFlat-arm and angled-arm options: flat arm sits down onto the deck, angled arm suits an existing fall or a dressed detail\u003c\/li\u003e\n\u003cli\u003eThree colours through the whole range — black, grey and white — colour-fast, no painting required\u003c\/li\u003e\n\u003cli\u003eSold as 12m or 24m packs of 3m lengths, so a typical garage or extension perimeter arrives in one order\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eSuitable roof types — please read before ordering\u003c\/h3\u003e\n\u003cp\u003eThese trims are designed for \u003cstrong\u003eGRP\/fibreglass, roofing felt, asphalt and liquid-applied flat roofs\u003c\/strong\u003e.

For face height, the trim should cover your roof build-up plus a sensible overhang onto the fascia — a slim 40mm or 50mm face suits a shallow deck, while 150mm and 200mm faces are for deep insulated build-ups or where you want a bolder shadow line. Choose the flat arm for a flat deck and the angled arm where the arm needs to sit on a fall or over an existing surface.
