You spend money on Google Ads. Someone searches "roofer near me," clicks your ad, lands on your website, reads your reviews, looks at your photos — and then closes the tab and does not call. They were interested. They just were not ready right then. Maybe they needed to talk to their spouse. Maybe they got distracted. Maybe they wanted to get one more quote.
That visitor cost you somewhere between £3 and £12 in click spend. You got nothing back for it. And because most roofing websites convert at 3–8% of visitors, that scenario describes 92–97% of everyone who clicks your ads.
Remarketing is the mechanism that lets you stay in front of those people after they leave — showing them your ad as they read the news, watch YouTube, or search Google again over the following days. It does not bring back everyone who bounced, but it meaningfully increases the proportion who eventually convert, at a cost significantly below what you paid to get them to your site in the first place.
This guide covers how remarketing works technically, which audiences to build for a roofing business specifically, how to set it up in Google Ads, what your ads should say, how to manage the budget, and what realistic results look like.
How Google Ads remarketing actually works
Remarketing works by placing a small piece of code — a tag — on your website. When someone visits, the tag adds them to a remarketing audience list stored in your Google Ads account. You then create campaigns that specifically target people on that list, rather than targeting broad keyword searches.
There are two distinct types of remarketing in Google Ads that are relevant for roofing contractors, and they work differently enough that they need separate strategies:
Display Remarketing
Banner and image ads shown to past visitors as they browse other websites
When a homeowner who visited your site goes to read a news article, check a recipe, or watch a YouTube video, your ad appears as a banner — typically in the sidebar, above content, or as a pre-roll. This is the classic "following you around the internet" experience that most people are familiar with from seeing the same shoe ad on every website after looking at it once.
For roofing, Display remarketing works as a trust-maintenance mechanism. The homeowner who saw your site and was considering you gets repeated visual exposure to your business name, your tagline, and your phone number over the following days. When they are finally ready to act — the ceiling stain gets worse, they show their spouse the photos, they decide they cannot put it off any longer — you are the name they remember.
- Cost: Very low — £0.15–£0.60 per click; most impressions are free
- Audience requirement: 100 active users in the last 30 days
- Ad format: Responsive Display Ads (images + headlines + descriptions, Google auto-assembles)
- Best membership duration: 30–90 days depending on job type
RLSA — Remarketing Lists for Search Ads
Bid adjustments on search ads specifically for people who have visited your site
RLSA does not create a separate campaign of display banners. Instead, it allows you to adjust your bid on existing search keywords when the person searching is someone who has already been to your website. If someone who visited your site last week searches "roofer in [your town]" again, you can tell Google to bid 50–100% more than usual for their click — because that person already knows who you are and is significantly more likely to convert than a stranger making the same search.
RLSA is the more technically valuable remarketing type for roofing because roofing is primarily a search-driven purchase. The person who revisits Google and searches for a roofer is actively buying — and they already met you. Being the top result for that person is worth paying considerably more for than being the top result for a cold stranger.
- Cost: Higher than standard Display but still within your search campaign budget
- Audience requirement: 1,000 active users (much harder for local roofers to reach)
- Ad format: Standard text search ads — same as your existing campaigns
- Best used with: Bid-only mode (show ads to everyone, but bid more for past visitors)
Which audiences to build for a roofing business
Not all website visitors are equally worth remarketing to. A homeowner who spent three minutes on your services page and visited your contact page is far more valuable to remarket to than someone who bounced from your homepage in five seconds. Building separate audience segments — and treating them differently — is what separates a sophisticated remarketing setup from a blunt "show ads to everyone" approach.
Contact / quote page visitors who did not convert
These people reached your contact page or started filling in a form and stopped. They are as close to a lead as a non-converter gets. Remarket aggressively to this group for 14–30 days.
Bid adjustment: +80–100% for RLSAServices page visitors (3+ minutes on site)
Someone who spent meaningful time reading your services page is actively evaluating. They compared your offering against their need. Worth remarketing for 30 days.
Bid adjustment: +50–70% for RLSAAll website visitors (past 30 days)
The broadest useful remarketing audience — anyone who visited any page. Lower intent than specific page visitors but still 3–5× more likely to convert than cold audience. Good for Display campaigns.
Bid adjustment: +20–40% for RLSAPast 60-day visitors (planned works)
For re-roofing, re-felting, and chimney work — longer consideration cycles mean a 60-day window is appropriate. These visitors may still be in the research phase.
Bid adjustment: +15–25% for RLSAExisting customers (converter list)
Create a "converters" audience from your thank-you page or confirmed booking confirmation page. Exclude this from all remarketing campaigns — you are paying to reach people who already booked you.
Exclusion list — add to every campaignCustomer Match (email list)
Upload your past customer email list to Google Ads. When those people search on Google, you can bid differently for them or exclude them. Requires the RLSA 1,000-user threshold but can be powerful for letting agent contacts.
Requires Customer Match activationSetting up remarketing: the technical steps
-
1Install the Google Ads tag on your website
In Google Ads, go to Tools & Settings → Shared Library → Audience Manager → Your Data Sources. Create a Google Ads tag and copy the Global Site Tag code. If your website is built on WordPress, use the Site Kit by Google plugin (free) which installs this automatically when you connect your Google Ads account. If your site is plain HTML (like ukroofingleads.com), paste the tag code into the <head> section of every page — or use Google Tag Manager as a container.
✅ Verify the tag is firingInstall the Chrome extension "Google Tag Assistant" and visit your own website. The extension will confirm whether the Google Ads tag is present and firing correctly on each page. Do not proceed with building audiences until the tag is verified — audiences built on a misfiring tag will never populate.
-
2Create your remarketing audiences in Audience Manager
Go to Tools & Settings → Audience Manager → Audiences. Click the + button to create a new audience. Select "Website visitors" as the audience source. Build the following audiences in order of priority: (1) All website visitors, membership duration 30 days. (2) Contact page visitors, 30 days. (3) Services page visitors, 60 days. (4) Converters / thank-you page visitors, 540 days (this is the exclusion list). Name each audience clearly — "Remarketing — Contact Page 30d" and so on.
-
3Wait for audiences to populate
Google cannot serve remarketing ads until your audience reaches the minimum size — 100 users for Display, 1,000 for Search/RLSA. Depending on your current traffic, this may take days or weeks. You can check audience sizes in the Audience Manager table. During this period, your existing search campaigns continue running normally — no disruption.
-
4Create your Display remarketing campaign
In Google Ads, create a new campaign → Display → Create a campaign without goal guidance → Remarketing. Set the geographic targeting to your service area only — not the whole UK. Under Audiences, select your "All website visitors" list plus your "Contact page visitors" list. Add your "Converters" list as an audience exclusion. Set a modest daily budget (£3–£7/day for a local roofer to start) and a target CPC of £0.40–£0.60 or let Google optimise with Target CPA if you have enough conversion data.
-
5Build your Responsive Display Ads
Google Ads Responsive Display Ads automatically combine the assets you provide — images, logos, headlines, and descriptions — into different ad formats for different placements. Upload: your logo, 3–5 square images (1200×1200, ideally photos of your completed work), 3–5 landscape images (1200×628), up to 5 headlines (30 characters each), and up to 5 descriptions (90 characters each). Google tests combinations and optimises toward the best performers. See the ad examples section below for headline and description guidance.
-
6Add RLSA bid adjustments to your search campaigns (when ready)
Once your "All website visitors" audience reaches 1,000 users, go to your existing search campaigns → Audiences tab → Add an audience in "Observation" mode (not Targeting). Select your visitor lists. Then set a positive bid adjustment — start with +30% for all visitors and +60% for contact-page visitors. Monitor for two weeks and adjust based on conversion data.
What your remarketing ads should say
Remarketing ads are different from cold acquisition ads because the audience already knows who you are. Your job is not to introduce yourself — it is to remind them, reduce their hesitation, and give them a specific reason to come back now rather than later. The messaging should acknowledge the consideration stage they are in without being creepy about knowing they visited your site.
Headlines that work for roofing remarketing
What to avoid in remarketing ad copy
- Specific review count ("80+ 5-star reviews")
- Friction-reducing offers ("Free written quote")
- Urgency with a reason ("Before the winter rain")
- Local signals ("Covering [your town] and surrounding areas")
- Direct call to action ("Call now," "Book a quote")
- Credibility signals ("Fully insured," "NFRC member")
- Response time commitment ("Same-day callback")
- Generic brand slogans ("Quality roofing you can trust")
- No clear call to action
- Referencing the visit ("You checked us out — come back")
- Overlong descriptions nobody reads in a banner
- Too many competing messages in one ad
- Pricing claims without context ("From £299")
- Stock imagery instead of your own work photos
Budget, bidding, and what to expect
Remarketing for a local roofing business is inherently modest in scale. Your website does not get thousands of visitors a day — it gets dozens. Your remarketing audience is therefore small, and the total spend will be small by definition. This is actually a feature, not a bug: you are concentrating your ad spend on the highest-value, most convertible segment of your potential audience.
Monthly Display remarketing budget
For a local roofing contractor with 100–500 website visitors per month, a Display remarketing budget of £50–£150/month is typically sufficient. At £0.30 average CPC, that is 170–500 additional clicks from people who already know you. The total spend is low because the audience pool limits how often ads are shown.
Frequency capping
Set a frequency cap to limit how many times one person sees your ad per day and per week. A reasonable cap is 3 impressions per day / 15 per week. Without a cap, a small audience gets oversaturated — the same 50 people see your ad 20 times a day and start finding it irritating rather than reassuring. Set the cap in your Display campaign settings under "Additional settings → Frequency management."
Membership durations by job type
Emergency repair searchers: 7–14 days. If they have not acted in two weeks they have sorted it. Re-roofing / planned works searchers: 60–90 days — these are longer consideration purchases. Contact-page visitors who did not convert: 30 days — this is your highest-priority audience and worth spending the most on.
Smart Bidding vs manual CPC
For a small remarketing campaign with limited conversion data, Manual CPC with a set maximum of £0.50–£0.70 gives you more control. Once you have 30+ conversions tracked through the campaign, switch to Target CPA or Target ROAS — Google's smart bidding needs sufficient data to optimise effectively and will underperform on thin data sets.
How to allocate your Google Ads budget across search and remarketing
For a roofing contractor running a balanced Google Ads account, here is the recommended allocation between cold search, remarketing Display, and any additional channels:
On a £500/month Google Ads budget, this means approximately £350 on cold search, £75 on Display remarketing, £50 on Performance Max, and £25 on Local Services Ads. The remarketing allocation is modest in absolute terms but disproportionately impactful because it targets the most qualified segment of your audience.
Common remarketing mistakes roofing contractors make
| Mistake | What happens | Fix |
|---|---|---|
| No frequency cap | Same homeowners see your ad 20+ times per day — irritating, not persuasive | Set max 3 impressions/day, 15/week in campaign settings |
| Not excluding converters | Budget wasted showing ads to people who already booked you | Create a "Thank-you page visitors" audience and add as exclusion to every remarketing campaign |
| Same ads for all visitors | Contact-page abandoners (high intent) get the same message as homepage bouncers (low intent) | Create separate ad groups with separate messaging per audience segment |
| Remarketing nationally | Spend wasted on visitors outside your service area | Set geographic targeting to your service area only — same as your search campaigns |
| Using only one ad variant | Ad fatigue — same people see the same creative for weeks and stop registering it | Create 3–4 responsive display ad variants with different messaging themes; let Google rotate and optimise |
| Starting with RLSA before traffic exists | Audience never reaches 1,000 users; campaign serves no impressions; wasted setup time | Start with Display remarketing (100-user minimum); add RLSA only when traffic justifies it |
| Membership duration too short for planned works | Re-roofing prospects (30-90 day decision cycle) fall off the list before they are ready to act | Set 60–90 day membership for services pages; 7–14 days for emergency repair pages |
Measuring remarketing success: the right metrics
Remarketing has a measurement challenge that cold search does not: the conversion may be attributed to a search click that happened days after the remarketing exposure, not to the remarketing click itself. This is the multi-touch attribution problem. A homeowner who saw your remarketing banner for five days, then searched "roofer [town]" and clicked your search ad to call — Google's default "last click" attribution gives all the credit to the search click and none to the remarketing campaign that kept you visible.
Practical ways to measure remarketing impact accurately:
- 📊Compare conversion rate of new users vs returning users in Google Analytics — returning users (those who have been to your site before) should convert at a meaningfully higher rate than new users. If they do not, your remarketing is not working or your audience composition is wrong.
- 📈Use Data-Driven Attribution in Google Ads — switch from Last Click to Data-Driven attribution in your Ads settings. This model distributes conversion credit across all touchpoints in the path, giving remarketing its fair share of the credit for conversions it assisted.
- 🔄Monitor the "Assisted conversions" report in Google Analytics — this shows conversions where a channel appeared in the path but was not the final touchpoint. Display remarketing almost always shows high assisted conversion values that last-click attribution misses entirely.
- 📞Ask new callers directly — "How did you find us?" remains the most direct attribution method for phone call leads. When a caller says "I kept seeing your ad everywhere" — that is your remarketing working, and it will not show up in your click data as a remarketing conversion.
- 💹Track view-through conversions — in Google Ads, view-through conversions record when someone saw (but did not click) your Display ad and then converted within a set window. Enable this in your conversion tracking settings and set a window of 7–14 days. This is imperfect but gives you a directional sense of the brand impression value.
How remarketing fits into your full Google Ads strategy
Remarketing is not a standalone strategy — it is a layer that sits on top of everything else you are doing to drive traffic to your website. A roofer with no cold search campaign, no Google Business Profile, and no organic traffic has no remarketing audience to build. The funnel has to exist before remarketing can plug the holes in it.
Where remarketing sits in the customer journey
Awareness: Google Business Profile (Maps listing, photos, reviews) and organic search put you in front of homeowners who are searching. This is the top of the funnel and the primary driver of new website visits.
Consideration: Google Ads search campaigns bring in high-intent paid traffic — people who searched a commercial roofing keyword and clicked your ad. Your website, reviews, and case studies do the conversion work here. Most do not convert on the first visit.
Remarketing: Display remarketing and RLSA pick up the 92–97% of visitors who left without converting. Over the following days and weeks, your ads maintain brand presence while the homeowner completes their decision process. When they are ready to act, you are top of mind — and potentially top of the search results when they search again (via RLSA bid adjustment).
Conversion: The phone call, contact form submission, or direct booking. This is the goal of the whole system. Remarketing's contribution is the difference between converting 3–5% of your traffic and converting 6–10%.

Frequently Asked Questions
What is Google Ads remarketing for roofers?
Google Ads remarketing is a form of paid advertising that shows your ads specifically to people who have already visited your website. For roofing contractors, this means a homeowner who looked at your services page but did not call will see your display or search ads as they browse other websites or search Google again over the following days or weeks. Remarketing ads typically cost less per click than standard search ads because they target a smaller, pre-qualified audience who already has some familiarity with your business.
How much traffic do I need before remarketing makes sense?
Google requires a minimum of 100 active users in a remarketing audience over the past 30 days before Display ads can be served, and 1,000 active users for Search remarketing (RLSA). For most roofing contractors, this means your website needs at least 100–150 visitors per month before Display remarketing becomes viable. If you are below this threshold, prioritise getting more traffic first — through local SEO, Google Ads search campaigns, or Google Business Profile optimisation — then activate remarketing once the audience is large enough.
Does Google Ads remarketing work for local roofing businesses?
Yes — local service businesses like roofing contractors are among the best use cases for remarketing. The pool of people actively considering a roofing contractor in a local area at any one time is small, and remarketing concentrates your spend specifically on that pre-qualified group. A homeowner who visited your site, saw your reviews, and was considering calling is far more likely to convert on a remarketing ad than a complete stranger seeing a cold ad. The average roofing decision takes 7–21 days from first search to booking — remarketing covers that entire window.
What is RLSA and do I need it for my roofing ads?
RLSA (Remarketing Lists for Search Ads) allows you to modify your search ad bids for people who have previously visited your website. When someone who has been to your site searches "roofer near me" again, you can bid 50–100% more than usual to ensure your ad appears prominently. It requires 1,000 active users to activate, so it is not immediately accessible for most local roofing contractors. Start with Display remarketing (100-user minimum) and add RLSA when your traffic volume justifies it.
How long should I remarket to someone who visited my roofing website?
The appropriate remarketing window depends on the job type. For emergency repair searchers, 7–14 days is sufficient — if they have not acted in two weeks they have already found someone. For re-roofing and planned maintenance searchers, 60–90 days is appropriate given the longer decision cycle. Contact-page abandoners — people who nearly called — should be remarketed for 30 days at higher bid adjustments. Using different membership durations for different audience segments is standard best practice.
Is Google Ads remarketing expensive for roofers?
Display remarketing is relatively inexpensive — typical CPCs of £0.15–£0.60 compared to £3–£12 for cold search ads targeting roofing keywords. The limitation is reach: your remarketing audience is smaller than your full search audience, so total monthly spend tends to be modest (£50–£200 for a local roofer). RLSA sits within your existing search campaign budget as a bid adjustment rather than a separate spend. The combined effect is a meaningful lift in conversion rate for a small incremental cost.
Every visitor who left without calling is still a potential lead
Remarketing closes the gap between the traffic you are already paying for and the conversions that traffic should be generating. Combined with strong local SEO and a well-managed search campaign, it is the last piece of a complete Google Ads strategy for UK roofing contractors.
