    Technical SEO for Roofing Websites: The Complete Checklist

    Roofer installing shingles on a residential roof — technical SEO for roofing websites

    Technical SEO issues silently destroy roofing rankings. A site can have excellent content and a strong Google Business Profile — yet still fail to reach page one because of fixable technical problems that most contractors never discover.

    This checklist covers every critical technical SEO element for roofing websites — from Core Web Vitals to schema markup. Run through it with your current site to identify the technical gaps costing you rankings.

    Core Web Vitals — Google's Page Experience Signals

    Core Web Vitals are Google's quantitative measure of page experience. They became official ranking factors in 2021 and continue to carry significant weight, particularly for mobile results where most roofing searches happen.

    LCP

    Largest Contentful Paint

    ✅ Good: < 2.5s

    ❌ Poor: > 4.0s

    How quickly your main content loads. Usually your hero image or largest text block.

    INP

    Interaction to Next Paint

    ✅ Good: < 200ms

    ❌ Poor: > 500ms

    How quickly your page responds to user input. Slow scripts are the most common culprit.

    CLS

    Cumulative Layout Shift

    ✅ Good: < 0.1

    ❌ Poor: > 0.25

    How much your page layout shifts while loading. Missing image dimensions cause this most often.

    The Complete Technical SEO Checklist

    🚀 Page Speed & Performance

    Images compressed and served in WebP/AVIF format
    Images lazy-loaded below the fold
    Hosting on a fast server (target < 200ms TTFB)
    JavaScript deferred or async where possible
    CSS and JS files minified
    Browser caching enabled
    Project photo gallery images uncompressed (most common issue on roofing sites)Fix This
    Google Maps iframe blocking renderFix This

    📱 Mobile Optimization

    Over 70% of roofing searches happen on mobile. Google uses mobile-first indexing — meaning your mobile site is what Google ranks, not your desktop version.

    Fully responsive design — no horizontal scrolling on mobile
    Phone number is a tap-to-call link on mobile
    Contact form accessible within 1–2 taps from any page
    Font size minimum 16px for body text — no zooming required to read
    Touch targets (buttons, links) minimum 44x44px
    Popups or interstitials covering content on mobile entry

    🔒 Security & Technical Foundation

    HTTPS enabled with valid SSL certificate
    No mixed content warnings (HTTP assets on HTTPS pages)
    XML sitemap created and submitted to Google Search Console
    Robots.txt configured correctly — not blocking important pages
    Canonical tags implemented on paginated or filtered pages
    301 redirects in place for any changed URLs
    HTTP to HTTPS redirect chains (3+ redirects)
    Old site pages returning 404 that should be redirected

    🏷️ Schema Markup

    Schema markup helps Google understand your business and can trigger rich results that dramatically increase click-through rates.

    LocalBusiness or RoofingContractor schema on homepage
    Service schema on each service page
    FAQPage schema on FAQ sections
    BreadcrumbList schema on all inner pages
    AggregateRating schema for review counts
    No schema markup at all (most common on roofing sites built on page builders)

    The Most Common Technical SEO Failures on Roofing Websites

    After auditing hundreds of roofing websites, we consistently find the same technical issues causing the most ranking damage:

    Uncompressed Project Photos

    High Impact

    The #1 speed killer on roofing sites. A 10-photo gallery with uncompressed images can add 8+ seconds of load time on mobile.

    Missing or Incorrect Schema

    High Impact

    Most roofing sites have zero structured data markup, leaving rich result opportunities (star ratings, FAQs) completely uncaptured.

    Duplicate Location Pages

    Medium Impact

    Location pages using the same content template with only the city name changed trigger duplicate content penalties.

    Broken Redirect Chains

    Medium Impact

    Old website migrations that created redirect chains dilute link equity and slow page load — often going undetected for years.

    No Mobile Click-to-Call

    High Impact

    Phone numbers displayed as plain text on mobile can't be tapped. This kills the most direct conversion path for mobile visitors.

    Crawl Errors on Service Pages

    Medium Impact

    Service and location pages blocked by robots.txt or returning errors prevent Google from indexing your most valuable content.
