Roofline, Fascias, Soffits and Guttering in London Homes: Products and Costs 2025

UPVC (UNPLASTICISED POLYVINYL CHLORIDE) REPLACEMENT ROOFLINE BOARDS ARE THE DOMINANT MATERIAL CHOICE FOR LONDON RESIDENTIAL ROOFLINE RENOVATION. KEY PRODUCTS USED IN LONDON IN 2025: EUROCELL MODUS FASCIA AND SOFFIT — EUROCELL IS THE LEADING UK MANUFACTURER OF UPVC ROOFLINE PRODUCTS; THEIR MODUS SYSTEM (SQUARE-EDGE FASCIA, VENTED SOFFIT, OGEE OR SQUARE-EDGE TRIM PIECES) IS STOCKED BY ALL MAJOR LONDON BUILDERS MERCHANTS INCLUDING TRAVIS PERKINS AND JEWSON. AVAILABLE IN WHITE, ANTHRACITE GREY (RAL 7016) AND CHARTWELL GREEN AS STANDARD. MARLEY FOREVER FASCIA — THE MARLEY ALUTEC FOREVER FASCIA IS A STEEL-REINFORCED UPVC PRODUCT PROVIDING IMPROVED RIGIDITY FOR LONGER SPANS; POPULAR FOR LARGE DETACHED LONDON PROPERTIES WITH LONG FASCIA RUNS OVER WIDE BAYS. GENERAL FOAMEX FASCIA — A CLOSED-CELL FOAM UPVC ALTERNATIVE TO STANDARD HOLLOW UPVC, USED BY SOME LONDON CONSERVATION-AREA-ADJACENT CONTRACTORS FOR ITS BETTER WORKABILITY (CAN BE ROUTERED AND PROFILED MORE LIKE TIMBER). ANTHRACITE GREY UPVC ROOFLINE — RAL 7016 ANTHRACITE GREY IS THE MOST POPULAR COLOUR FOR CONTEMPORARY LONDON PROPERTY RENOVATIONS (REPLACING STANDARD WHITE); MATCHES GREY ALUMINIUM WINDOWS AND CONTEMPORARY FRONT DOORS. BROWN UPVC — TRADITIONALLY POPULAR IN 1970S AND 1980S LONDON SUBURBAN HOUSING; INCREASINGLY BEING REPLACED WITH WHITE OR GREY.

GUTTERING IN LONDON RESIDENTIAL PROPERTIES COMES IN SEVERAL PROFILES AND MATERIALS. THE MOST SPECIFIED IN LONDON IN 2025: UPVC HALF-ROUND GUTTER — THE MOST WIDELY INSTALLED GUTTER PROFILE IN LONDON FOR BUDGET AND MID-RANGE PROJECTS; STANDARD SIZES ARE 112MM HALF-ROUND (MARSHALL TUFFLEX, MARLEY, OSMA) IN WHITE OR ANTHRACITE GREY. UPVC OGEE GUTTER — A DECORATIVE K-SECTION (OGEE) PROFILE THAT REPLICATES THE APPEARANCE OF TRADITIONAL CAST IRON ON LONDON VICTORIAN AND EDWARDIAN PROPERTIES. MOST COMMON LONDON SPECIFICATION FOR PERIOD PROPERTIES REPLACING ORIGINAL CAST IRON: 113MM OGEE IN WHITE OR BLACK; AVAILABLE FROM MARSHALL TUFFLEX AND MARLEY. CAST IRON GUTTERING — THE ORIGINAL AND MOST APPROPRIATE MATERIAL FOR LONDON LISTED BUILDINGS AND HIGH-END CONSERVATION AREA PROPERTIES. CAST IRON HALF-ROUND AND OGEE PROFILES ARE AVAILABLE FROM HERITAGE SUPPLIERS INCLUDING FORGE RECLAIMED (RECLAIMED CAST IRON), CAST IRON GUTTERS DIRECT (NEW CAST IRON) AND BRETT MARTIN POLYPIPE IRON EFFECT (HIGH-QUALITY UPVC REPLICA THAT MATCHES CAST IRON AESTHETICALLY). ALUMINIUM GUTTERING — LINDAB RAINLINE IS THE MOST SPECIFIED ALUMINIUM GUTTER SYSTEM IN LONDON FOR COMMERCIAL AND PREMIUM RESIDENTIAL PROJECTS; AVAILABLE IN ANY RAL COLOUR (ANTHRACITE GREY AND BLACK MOST POPULAR IN LONDON); LIGHTWEIGHT, MAINTENANCE-FREE AND DURABLE FOR 30+ YEARS.

THE CHOICE BETWEEN CAST IRON AND UPVC GUTTERING IS A SIGNIFICANT AESTHETIC DECISION FOR LONDON VICTORIAN AND EDWARDIAN PROPERTIES. ORIGINAL CAST IRON — LAST 80-100 YEARS IF PROPERLY MAINTAINED (PAINTED INSIDE AND OUT EVERY 10 YEARS WITH BLACK BITUMEN PAINT FOR INSIDE AND STANDARD GLOSS FOR OUTSIDE). EXPENSIVE TO REPLACE WHEN FAULTY (£150-£300/METRE INCLUDING FITTINGS AND INSTALLATION). HEAVY — REQUIRES PROPERLY FIXED RAFTER FEET OR FASCIA BOARDS TO TAKE THE LOAD. LISTED BUILDINGS MUST RETAIN CAST IRON OR A LIKE-FOR-LIKE REPLACEMENT APPROVED BY LISTED BUILDING CONSENT. UPVC OGEE — A MUCH LOWER COST ALTERNATIVE (£40-£80/METRE INSTALLED) THAT VISUALLY REPLICATES CAST IRON REASONABLY WELL, ESPECIALLY IN BLACK OR DARK GREY. SERVICE LIFE 20-25 YEARS. MAINTENANCE-FREE. NOT APPROPRIATE FOR LISTED BUILDINGS BUT ACCEPTABLE IN MOST LONDON CONSERVATION AREAS ON NON-LISTED PROPERTIES. BRETT MARTIN ROOFLINE IRON EFFECT — A PREMIUM UPVC PRODUCT THAT VERY CLOSELY REPLICATES CAST IRON APPEARANCE AT SIGNIFICANTLY LOWER COST AND WEIGHT THAN TRUE CAST IRON; SPECIFIED BY MANY LONDON CONSERVATION AREA RENOVATION PROJECTS AS A COMPROMISE BETWEEN AUTHENTICITY AND PRACTICALITY.

A FULL LONDON TERRACE ROOFLINE REPLACEMENT TYPICALLY INVOLVES: SCAFFOLD — ACCESS SCAFFOLDING IS REQUIRED FOR SAFE WORKING AT EAVES LEVEL. FOR A STANDARD LONDON MID-TERRACE, A LIGHTWEIGHT INDEPENDENT SCAFFOLD OR TOWER SCAFFOLD IS USED FOR 2-3 DAYS; THE SCAFFOLDING HIRE IS TYPICALLY £200-£500 FOR A SHORT ACCESS PERIOD. REMOVAL — OLD TIMBER FASCIAS, SOFFITS AND GUTTERS ARE STRIPPED AND REMOVED. LEAD FLASHING AT JUNCTIONS AND ABUTMENTS SHOULD BE CHECKED AND REPLACED WHERE NECESSARY DURING THE WORKS. FASCIA INSTALLATION — NEW UPVC FASCIA BOARDS ARE FIX-CAPPED OVER THE EXISTING RAFTER FEET; THIS IS THE STANDARD METHOD FOR LONDON REPLACEMENT RATHER THAN A FULL RAFTER FOOT REPLACEMENT (WHICH WOULD REQUIRE ROOF TILE REMOVAL). WHERE EXISTING FASCIAS ARE VERY ROTTEN (SOFT, SPONGY, CRUMBLING), FULL REPLACEMENT OF RAFTER FEET MAY BE NECESSARY. SOFFIT — UPVC VENTED SOFFIT BOARDS FIT BETWEEN THE WALL AND THE FASCIA; THE VENTED SOFFIT ALLOWS ROOF SPACE VENTILATION AS REQUIRED BY BS 5250. GUTTERING — NEW GUTTERING IS FITTED WITH THE CORRECT FALL (1:600 MINIMUM GRADIENT TOWARD THE DOWNPIPE) AND NEW DOWNPIPES ARE FITTED WITH THE APPROPRIATE SHOES, BENDS AND CONNECTIONS TO THE DRAINAGE GULLY.
