How this page is built

Nobody pays to appear on this page, and position cannot be bought. A company is listed only where the official register showed it holding a current license when we checked on September 4, 2026.

Ranked by years licensed.
Left off anything expired on the date we checked, or carrying any status other than current.
Not published at all until at least 3 roofing companies pass that check. At most 10 appear - a cut through the ranking, not a further test.

The full method, including what each register does and does not publish.

Tuolumne County roofing licensure at a glance

California licenses contractors by classification and CSLB publishes one on every record, so supply can be counted exactly: 16 active C-39 roofing licenses in Tuolumne County, 3 of them registered in Groveland. CSLB also publishes a real original issue date, which Washington's registry does not, so tenure is measurable here: the median Groveland license has been held 13 years, and the longest-standing one dates to 1981. California law requires workers' compensation cover for C-39 licensees, so it is a legal baseline rather than a way to tell two contractors apart: 3 of Groveland's 3 licenses (100.0%) carry a current policy in CSLB's file, and we do not rank on it. The contractor bond is not a signal here: 16 of the county's 16 licenses carry the same $25,000 bond California sets by statute. 1 county license reaches its expiration date within the next 90 days. CSLB cannot link straight to a license record, so every listing above shows its number for you to type into CSLB's license lookup. How we verify.

Roofers in Groveland: common questions

How many licensed roofers are there in Groveland?

3 active C-39 roofing licenses are registered in Groveland, out of 16 across Tuolumne County. 3 Groveland-registered companies passed our license verification, and all 3 are listed on this page. Only licenses CSLB shows as CLEAR and unexpired are listed.

Does California license roofers?

Yes. California licenses contractors by classification, and C-39 is the CSLB classification that authorises this work, unlike Texas, which licenses no roofing contractors at all. 3 active C-39 roofing licenses are registered in Groveland and 16 across Tuolumne County, the longest-standing issued in 1981. Only CLEAR, unexpired licenses appear here.

How do I check a roofer's license in California?

Every listing above shows its CSLB license number. CSLB cannot link straight to a record, so open its license lookup and type the number in: it shows status, expiration, the contractor bond and workers' compensation cover, which California requires of C-39 licensees and 3 of Groveland's 3 currently carry. 1 Tuolumne County license expires within 90 days.

Why is a company not on this list?

A company appears only when we can match it to a current record in the register this page is verified against - 3 companies passed that match for Groveland. A credential that is expired or suspended, or a business we cannot conclusively match to a current record, never appears. A listed business that believes its information is wrong can reach us through the contact and corrections page at homversa.com/contact. How current each date is, and what happens when a credential lapses, are explained on our methodology page.

Which nearby cities have verified roofers?

Sonora (5 verified), Twain Harte (3 verified), Oakdale (4 verified), Merced (8 verified) and Atwater (3 verified) each publish their own list, verified separately against the state register, so the counts differ city by city. The links are in the nearby-cities section below.
