Customer Ratings
Customer ratings shown here come from Google. They are separate from our editorial review above.
The distribution reflects the 685 Google reviews available when this profile's review data was last refreshed on October 5, 2026. Ratings and counts change continuously on Google, so figures here may lag the live profile slightly. We publish only the values returned by the source, never estimates for missing bands.

It holds position 6 in 10 Best Roofing Companies in Austin, TX (2026).

Coverage is as the business describes it, cross-checked against where its recent documented work is. A company will often travel beyond the areas listed here for a large job and decline a small one at the same distance, so confirm your address before scheduling.
Company Background
Ja-Mar Roofing & Sheet Metal runs its Austin office from 4101 Parkstone Heights Drive, and the company says it has been working in Texas since 1970. Google shows 4.9 stars from 685 reviews, read October 5, 2026. Its site claims more than 50,000 completed projects, which makes it one of the older firms in this ranking.
The company installs shingle and metal roofs on houses and commercial buildings, repairs roofs, and offers sheet metal fabrication. Metal is where the reviews concentrate. Clark chose Ja-Mar for a metal roof on a 40 year old house after comparing ratings and quotes, and Achal said the team had the most competitive quote and exquisite craftsmanship. Louise named Ken Kelly in sales and project coordinator Samantha Smith for keeping a rental home roof replacement on schedule. Pedro and Missy both praised Cody for keeping them informed, and Missy said the crew left her back porch cleaner than it had been in years.
On credentials, the site says Ja-Mar is a GAF Master Elite contractor and lists FORTIFIED Roof certification, a program that rates roofs for storm resistance. It runs a financing page, a referral program and a Roof for Troops page. Austin hours on Google run 6 AM to 9 PM on weekdays and 8 AM to 5 PM on Saturday, with Sunday closed. Because Austin is one of several Texas offices, ask whether your crew and coordinator work out of this one.
Ja-Mar suits owners planning a metal roof or a large replacement who want a long established firm. It suits less well someone with a small repair who wants to meet an owner, since the site names no owner. Before booking, ask for proof of insurance, the written warranty and the city of Austin permit, because Texas does not license roofers at the state level.
