Concord Roofing Company
Roofing, Solar, Siding & Gutters for Concord Homeowners
Straight Line Roofing & Construction brings three generations of roofing craft and 25-plus years of experience to Concord and the surrounding area. We’re the roofing and exterior contractor for homeowners who plan a roof replacement carefully and decide when they’re ready — on their own timeline, not a salesperson’s.
Founded May 21, 1999, on a roofing tradition that goes back three generations. Owens Corning Platinum Preferred Contractor and GAF Master Elite Roofer — designations held by fewer than three percent of roofing contractors nationwide. Now serving Concord, Pleasant Hill, Walnut Creek, and the surrounding communities.
Three Generations of Roofing Craft
Roofing runs in the family. The trade traces back to Cornell Roofing Company, founded by Jack Borba’s grandfather — a standard for quality that has carried through three generations to the company Jack runs today. When Jack founded Straight Line in 1999, he built it on what he’d grown up around: do the work right, stand behind it, and treat the homeowner like a neighbor.
That lineage is why we measure a roof in decades, not in this season’s lead quota. It’s also why, as we bring Straight Line to Concord, we bring the same standard the family has held for three generations — not a new brand testing a new market.

An Established Contractor, Now Serving Concord
Straight Line has operated continuously across Northern California since 1999 — a date that predates the storm chasers and pop-up roofing outfits that come and go after every big season. As we expand into Concord, we bring the same crews, the same manufacturer certifications, and the same owner who started the company.
When you call, you reach a local, owner-operated company that will still be here in fifteen years to honor the workmanship warranty on the roof we installed today. Our crews are licensed, insured, and certified by the manufacturers whose materials we install — Owens Corning, GAF, James Hardie, and LP SmartSide.
We work Monday through Friday, 8:30 AM to 5:00 PM, and we respect the schedule of homeowners who run businesses, work from home, or are managing their week around grandchildren and travel. No high-pressure sales calls. No vanishing same-day discounts. Just a written estimate and a clear explanation of the decision in front of you.
Credentials That Fewer Than 3% of Contractors Hold
Owens Corning Platinum Preferred Contractor · GAF Master Elite Roofer · James Hardie Certified Installer · LP SmartSide Certified Installer
These designations are not stickers that a contractor buys at the lumber yard. They require ongoing training, installation audits, and verified workmanship records. We hold them all.
Roofing Services in Concord

Roof Repair Services
Not every aging roof needs a replacement. We’re known for telling homeowners when a roof repair is the right call — and when it’s throwing good money after bad. Flashing damage, a few cracked tiles after a wind event, a localized leak around a skylight: we fix what’s broken and tell you honestly how much life is left in the rest of the roof. We handle shingle, tile, and flat roof repair across the area.

Roof Replacement Services
A roof replacement is a 25- to 50-year decision, depending on the material you choose. We install architectural and designer shingles from Owens Corning and GAF, standing-seam metal, concrete and clay tile, and flat-roof systems for porches and additions — and we walk you through the trade-offs so you understand exactly what you’re paying for and why.

Storm Damage & Insurance Claims
When a tree limb comes through the deck or a section of shingles lifts in a storm, we secure the roof, document the damage for your insurance carrier, and walk you through the claim. We’ve worked with most major California carriers since 1999 and know what they need to approve a clean claim.
Financing as a Cash-Flow Strategy
Most of the homeowners we work with could write a check. They choose to finance for the same reasons they keep a financial planner on retainer: preserving liquid assets, managing distributions, and avoiding the liquidation of investment positions in a high-tax year. Through Regions and Enerbank USA, we offer financing terms that function as a treasury tool — not as affordability help.
Additional Exterior Services

Solar Roofing
We integrate solar panel systems with new and existing roofs, coordinating the roof and solar install so you’re not paying twice to lift and reset panels when the underlying shingles fail.

Gutters
We install, repair, and replace seamless gutters sized for the rainfall a home actually sees — not the undersized stock gutters most production builders installed decades ago.

Siding & Windows
As certified installers for James Hardie fiber cement and LP SmartSide engineered wood, we handle repairs, partial replacements, and full re-sides that modernize an older exterior without erasing its character.

Accessories
Ridge vents, attic fans, skylights, sun tunnels, upgraded underlayment, and ice-and-water shield in valleys all extend the working life of the roof above them. We’ll tell you which makes sense for your home and which are upsells you don’t need.
