Metal Roof vs Tile Roof
Heat, Noise, Leaks & Cost

Metal roof vs tile roof at a glance

Most Malaysian terrace houses, semi-Ds and bungalows were built with clay or concrete tiles. Metal roofing, either longspan (the smooth, wide-rib sheet sold under names like ZINCALUME and Colorbond) or IBR corrugated sheet, is what goes on most extensions, kitchen add-ons and car porches. When a roof is due for replacement, the question is whether to stay with tiles or change to metal. This table sets out the published differences:

The figures come from the re-roofing cost guide on this site. Neither roof is better in every column: tiles win on lifespan, heat and noise, metal wins on weight, speed and low pitches. The rest of this guide goes through each difference in turn.

Heat: which roof keeps the house cooler?

A tiled roof has the better thermal performance of the two. The tiles themselves are heavy and slow to heat through, and the air space under them helps. A bare metal sheet behaves very differently: sheets heat to well over 60°C in the afternoon sun and cool sharply in evening rain, and without a layer underneath, that heat radiates straight into the ceiling space.

The answer is not to avoid metal but to build it properly. The standing seam guide puts it plainly: insulation decides both heat gain and rain noise, and on a house it is the single biggest comfort difference between a good metal roof and a bad one. An underlay of sarking felt or reflective foil is critical for metal roofs in the Malaysian climate. A heat-reflective white topcoat is another upgrade, because it drops the sheet temperature.

Metal has one more heat-related habit: condensation forms on the underside of uninsulated sheets on humid nights. Over a bedroom that shows up as drips or stains that look like a leak. An underlay that drains to the gutter deals with it.

Rain noise

A tropical downpour on a bare metal sheet is loud, and this is the most common complaint about metal on a house. The published ratings are low for tiles, moderate for longspan with insulation, and high for IBR corrugated sheet. Two things reduce it: insulation under the sheet, and a solid deck. The standing seam guide notes that over a solid deck the roof is quieter in rain.

For a car porch or a store room, rain noise matters less. Over bedrooms and a living room it matters a lot, which is why many owners keep tiles on the main roof and use metal only on extensions.

How each roof leaks

The two roofs fail in different places. Tiled roofs rarely leak through the tile itself; the water gets in at cracked or slipped tiles, valleys, flashings, ridge mortar and an underlayment that has aged. Metal roofs usually leak at the screws, because each fixing is a hole sealed only by a rubber washer.

The repair bands are the headline ranges of the roof tile leak repair and metal roof leak repair guides. Both say the same thing: most leaking roofs need a diagnosis and a targeted repair, not a new roof. Leak detection is a separate paid visit at RM300 – RM800.

Weight, structure and roof pitch

Tiles are heavy, and a tiled roof needs timber or steel trusses that can carry them. Before putting new tiles on an old roof, check truss capacity. Metal is light, which is why it suits extensions built off an existing wall, and it is good for low-pitch roofs where tiles would not shed water fast enough.

The pitch point cuts both ways. A low-pitch extension roof is a metal job. A steep main roof built for tiles can take metal, but the batten layout changes, which is part of the switching cost below.

What each roof costs to replace

Indicative Klang Valley rates for 2026, quoted unchanged from the re-roofing cost guide on this site. The all-in column is for a 1,500 sq ft roof:

On material and labour alone, tile and longspan land in a similar band. Metal saves on labour and time, tiles cost less per sq ft of material. Stripping the old roof, new battens, gutters and access are extra lines on any re-roof quotation.

Switching from tile to metal, or back

Changing material is not a like-for-like swap. The same guide notes that switching from tile to metal or vice versa requires batten reconfiguration, adding RM3,000 – RM8,000. Its worked example is a single-storey terrace in Petaling Jaya with a 1,400 sq ft roof, replacing 25-year-old clay tiles with new concrete interlocking tiles, for a total estimate of RM18,700 – RM30,000. Switching to metal longspan for the same terrace would run RM16,000 – RM26,000 and take 2–3 fewer days on site.

In a terrace row, also think about the neighbours. A metal roof between two tiled roofs changes the look of the row, and the junctions at the party walls need proper flashings. Check with the local council or the management body before a change of roof material on a landed scheme with design rules.

Lifespan and upkeep

Re-roofing is usually considered when a roof is past 25–30 years for clay tiles or 15–20 years for metal sheet, and leaks keep coming back despite repairs. Upkeep differs too:

• Tile roofs: keep valleys and gutters clear, have cracked tiles and ridge mortar repaired early, and budget for the underlayment, which ages before the tiles do.
• Metal roofs: watch the screws and washers, reseal laps and flashings when they open, and deal with rust before it perforates. A worn but sound metal roof can often be coated instead of replaced; the roof rust grading guide explains how to tell.
• Both: never walk on the roof to inspect it. Tiles crack underfoot and thin sheets dent between purlins.

Which to choose, by situation

If you want metal on a main roof, look at the insulation and underlay in the quotation before the sheet itself. For a concealed-fix system with no screws through the weather surface, see standing seam metal roofs. For who to hire and what to ask, see how to choose a roofing contractor.

Sources & methodology

This comparison brings together figures already published in the site’s roofing guides: the re-roofing cost guide (material table, cost per sq ft, switching cost, worked example and replacement ages), the metal roof leak repair guide (sheet temperature, washer life, condensation, reflective topcoat, repair band), the roof tile leak repair guide (underlayment life, repair band) and the standing seam guide (insulation, solid deck). Prices are typical Klang Valley market ranges for 2026, not fixed rates; the right answer for a particular house depends on its structure, pitch and condition, confirmed on site.
