A Roofing-Led Website Built for F Martini Building
F Martini Building is a North London builder led by roofing, and we gave it a website to match: clean, trust-heavy and built to convert, with an instant cost calculator and 'get a free quote' buttons that never leave the screen. Here's how it turns homeowners into booked surveys.
Most building-company websites make the same mistake: they list every trade under the sun and end up standing for nothing. F Martini Building does the opposite — it leads with roofing, its core service, and lets everything else follow. When we designed and built the new site, we leaned into that focus rather than diluting it.
Who F Martini Building is
F Martini is a building contractor serving North London, Hertfordshire and Bedfordshire — core areas like Barnet, Finchley, Hampstead and Harrow, extending out to St Albans, Luton and Bedford. Roofing is the main service — re-roofs, flat roofs, repairs, leadwork, fascias, soffits and chimney work — backed by loft conversions, extensions, renovations and full refurbishments, with planning and building-control approvals handled in-house.
A hero that sets the tone
The homepage opens with a drone video and aerial shot of a freshly re-roofed home, under the line 'People build better places' and a plain-spoken promise: 'Roofing: re-roofs, flat roofs, repairs and leadwork, done properly.' It's confident and specific — you know within two seconds exactly what this company does and that it takes pride in doing it well.
Four pillars, one message: trust
Beneath the hero sit four value pillars — Precision, Trust, Craftsmanship and Modern building — that frame the whole experience. For a home-improvement business, where customers are inviting a team onto their property for weeks, that reassurance is the product. We reinforced it with real proof: five named client testimonials and a 5.0 rating from ten Google reviews, displayed where prospects will actually see them.
The cost calculator that does the hard part
The standout feature is an interactive cost calculator. A homeowner selects their project type, property type, roof covering and finish, and gets an instant estimated range — the sample shows £9,000–£14,000 for a standard re-roof on a terraced house — with a clear disclaimer that it isn't a formal quote. This is smart on two fronts: it answers the first question every homeowner has ('roughly what will this cost?') without a phone call, and it filters out tyre-kickers while warming up serious buyers before they ever enquire.
Built to convert, everywhere you look
Conversion is engineered into every screen. Persistent 'Call' and 'Get a quote' buttons sit in the header, and calls to action — 'Get a free quote', 'Book a roof survey', 'Book a free survey', 'Get an exact quote' — repeat down the page. A four-step process, from first site visit to handover, sets expectations and removes anxiety, and a simple enquiry form captures name, phone, email, location, service and message. There's even an area checker so visitors can confirm, instantly, that F Martini covers their town.
The result
The finished site is clean, image-led and reassuringly focused. It leads with a specialism, proves quality with real reviews and finished work, removes price uncertainty with the calculator, and makes getting a quote almost frictionless. For a local building company, that combination is the difference between a website that just sits there and one that books surveys while you sleep.
The takeaway for local trades
F Martini's site is a template for any local trades business: pick a lead service and own it; put real reviews where they count; take the fear out of pricing; and make the next step — a call, a quote, a survey — impossible to miss. Specialism plus reassurance plus frictionless enquiry is a quietly powerful formula.

Homeowners deciding on roofing want two things: a rough price, and the confidence you'll do it properly. F Martini's site gives them both up front — the calculator handles the price, the reviews and finished work handle the trust — so by the time someone enquires, they're already sold. — Daniel Nikolla, Founder of Merx Marketing
