Alcoil Roofing, Guttering & Sheet Metal Products Provide Protection you can Count on.

We build guarantees, warranties, & insurance into every roofing & guttering installation.

Replacing your roofing and guttering? Renovating and extending both? Upgrading one or the other?

Alcoil is your one-stop source for premium roofing and guttering supplies and installations. Family-owned and operated for 25 years, quality is the cornerstone of our business. From our free consultations, to our custom roofing and guttering designs, we drive solutions – not sales.

Our Sheet metal service grew from that ethos. Disappointed by suppliers, we established a sheet metal workshop to create the fittings we needed, in-house. Today, we help clients develop the products they need.

Trust your home and business to ours. Get responsive service, exceptional results, and careful, stress-free installations. Call Alcoil and speak with us today.

  • Licensed Professionals

    All our work is guaranteed.

    All Alcoil installations are performed by qualified, licensed plumbers. Within a week of installation, you’ll receive certification from the Plumbing Industry Commission, guaranteeing the work performed by your installer. Not a plumber overseeing inexperienced crews of installers, but that individual plumber’s work. We don’t deal with builders or transients, passing themselves off as qualified roofing and guttering installers. Alcoil provides genuine expertise and workmanship you can trust, guaranteed.

  • One-stop & Custom Solutions

    We provide a truly complete roofing & guttering service.

    Alcoil’s comprehensive roofing & guttering services combines the ease of a one-stop-shop with the customisation of a niche, specialist provider. Family owned and operated, we are small and nimble enough to provide individualised service and made-to-measure solutions. When it comes to our range of expertise, we punch above our weight. For a truly comprehensive roofing & guttering service, from custom flashings to roofing insulation, the only name you need to know is Alcoil. Call us today.

  • Quality

    Our commitment to quality knows no limits.

    From the advice we give – including when not to replace your roofing or guttering; to the flashings we design and manufacture in-house because market alternatives aren’t up to scratch; to the meticulous clean-up our installers perform - metal shavings can lead to rust; no aspect of your project is overlooked. We hold ourselves to the highest standards, and we’re confident we’ll meet yours. Learn more about Alcoil’s premium roofing, guttering & sheetmetal services today.

  • Free Consultations

    We provide genuinely free consultations & quotes without the sales tactics.

    Superior outcomes depend on strong beginnings. Alcoil starts every roofing and guttering project with a thorough, on-site inspection. We don’t do over-the-phone quotes or Google Earth guesstimates. We examine your system, in-person, in detail. We take scrupulous measurements, for accurate estimates. We document our findings and discuss your options. We leave you with a detailed quote and recommend that you get others. Because, while we may not win on price, we know we can’t be beaten on value.
