A roof is one of the most expensive parts of any building, and paradoxically one of the hardest jobs to keep flowing steadily into a roofer's order book. Roofers face intense activity in spring and summer, then watch demand drop as soon as the weather turns — except when a storm triggers a wave of emergencies (torn-off tiles, water ingress, damaged flashing). Between those two extremes, catching a homeowner at the right moment as they consider a full re-roof, roof insulation or an underlay upgrade remains a difficult exercise.
Buying qualified roofing leads smooths out that irregularity: instead of waiting on word of mouth, you receive requests from homeowners already thinking about the work. This guide is for roofers, tinsmiths and roofing companies considering buying leads: what it costs, how to judge the quality of a contact, and which legal framework applies in Switzerland.
Why buy roofing leads in Switzerland
The Swiss roofing market is defined by high-ticket jobs — a full re-roof, external insulation or re-waterproofing a flat roof quickly runs into tens of thousands of francs. A single signed contract can therefore pay back several dozen leads. That is what makes buying leads especially relevant in this sector: the acquisition cost, even for a well-qualified exclusive contact, stays marginal against the margin of a roofing project.
On top of that sits strong seasonality and weather dependence. A roofer has every interest in filling the schedule months ahead for the warm season, while keeping a flow of emergencies (storm damage, water ingress) coming in the off-season. A purchased lead is a request already made by a homeowner — you no longer need to convince someone their roof needs work, only to turn an existing project into a site visit and then a quote. For a business that wants to plan its workload rather than endure the quiet spells, it's a more predictable lever than an ad campaign whose return stays uncertain.
How much does a roofing lead cost in Switzerland
The price of a roofing lead depends on several factors: exclusivity level (exclusive lead vs. shared between several companies), the type of request (high-intent post-storm emergency vs. a longer-cycle planned re-roof), the nature of the work (spot repair, full re-roof, insulation, flat-roof waterproofing, flashing) and how well the contact is qualified (confirmed owner, roof area, project stage).
Compared with other trades, a roofing lead sits toward the top of the range: the average job ticket is high, so the value of a well-qualified contact is too. In Switzerland, observed amounts run from a few tens of francs for a shared lead on a simple quote request, up to a markedly higher price for an exclusive lead on a full re-roof with a decision-making owner. These figures stay indicative: they vary by provider, region, season and order volume. The relevant metric is not the unit price but the cost per signed job. The only way to get a reliable baseline is to request a detailed, no-obligation quote before starting.
- Shared lead (2 to 4 companies): the most accessible price point to test a provider on quote requests.
- Exclusive lead: higher cost, justified by the high ticket of a roofing job and a better conversion rate.
- Post-storm emergency (water ingress, torn-off tiles): high intent, usually priced above a planned re-roof.
- Cost per signed job: the only metric that truly matters, given the high value of a roofing project.
How to judge the quality of a roofing lead
A quality roofing lead shows signals specific to the trade, beyond mere contact details. The first is the contact's status: are they really the building's owner? A tenant cannot commission a re-roof, and a lead that isn't a decision-maker wastes a site visit for nothing. Next come the nature and scale of the project (repair, full re-roof, insulation, flat roof), the approximate roof area, and the stage (just gathering information, budget already set aside, permit under way).
Beyond these declared criteria, the real test of quality plays out over time: what share of leads turns into a visit, then a quote, then a signed job? A roofing decision cycle is longer than an emergency call-out, and a good provider accounts for that by sharing average conversion rates. Be wary of offers built purely on volume at the lowest possible price: a very cheap lead whose contact is a tenant, an abandoned project or a request already sent to five competitors ends up costing more than a slightly pricier contact who is genuinely the decision-maker.
- Owner status: the contact is the actual decision-maker, not a tenant or a mere browser.
- Framed project: type of work (repair, re-roof, insulation, flat roof), area and degree of urgency.
- Tracked consent: the owner agreed to be contacted by a roofer.
- Freshness: a lead delivered in real time, ahead of competitors, is worth far more than an old one.
Exclusive or shared leads: which to choose
A shared lead is sent to several roofing companies at the same time: it costs less to buy, but you're in direct competition on a quote. On a roofing job, though, the owner often compares three to five offers, and the decision hinges on trust as much as price — being the first to run a serious site visit changes everything. An exclusive lead is reserved for you alone: the price is higher, but you lead the relationship without racing other roofers.
The right choice depends on your positioning. Given the high value of a roofing contract, many companies favour exclusive leads: the extra cost per lead is quickly absorbed by the margin of a single signed job, and you avoid the price war that drags quotes down. Shared leads remain useful for testing a provider at lower risk or absorbing a dip in activity. Many companies start with shared leads to gauge quality, then move to exclusive once trust is established.
Legal framework: nLPD and consent
In Switzerland, any lead purchase must comply with the federal data protection act (nLPD). In practice, every owner whose details you receive must have given explicit consent to be contacted by a roofing professional — and that consent must be tracked by the lead provider, not simply claimed. This matters all the more because roofing requests sometimes follow a claim (storm, water damage) and may involve an insurer: the data must be used only for the purpose the customer provided it for.
Before buying, check that the provider can demonstrate the origin of consent (form, checkbox, timestamp) and that it doesn't resell the same data to an unlimited number of companies without disclosing it. As the receiving company, you remain responsible for how you handle the data you receive: keep it only as long as needed to follow up on the request, and respect the owner's right to opt out of further contact.
