About
Designer Roofing is based at 199 N McKinley St in Prosper, a fast growing Collin County town north of Frisco, and serves North Texas from there. The company was founded in 1993 by Dan Gerardis and Aaron Lenhart, who both still own and run it. The Better Business Bureau records a business start date of 1 October 1993, incorporation in February 2012, BBB accreditation since May 1994 and an A+ rating, with Dan M. Gerardis listed as managing member.
Metal is the clearest specialism. The company says it is one of only a few contractors in the Metroplex with crews experienced in residential metal roofing, and that it runs a dedicated team for stone coated steel and another for standing seam. Alongside metal it installs composition shingles, slate, custom fabricated metal and synthetic products including CeDUR synthetic shake and TAMKO Lamarite. Services listed include roof replacement, roof repair, residential roof inspections, hail damage assessment, fire damage roof inspection and insurance claim work.
The company displays GAF Master Elite and Owens Corning badges on its own About page. Those are company stated: no GAF or Owens Corning contractor directory profile for Designer Roofing could be retrieved to confirm them independently. Its BBB accreditation was confirmed directly on the BBB profile. A search of the RCAT contractor directory returned no record, so no RCAT Member or Licensed Roofing Contractor status is claimed here.

Insurance & credential verification
Texas does not issue a state roofing license, so we verify companies the way homeowners actually can: confirming insurance coverage, checking RCAT (Roofing Contractors Association of Texas) status, and checking city or county registration where the local jurisdiction requires one. Every credential below links to the actual issuing organization's own public lookup — don't just take our checkmark for it. Always ask for a current certificate of insurance before signing any contract.

InsuranceNot verified by us (we hold no certificate for this company — ask them for a current COI before signing)
RCAT statusNot listed
City/county registration
Registered — Dallas Check the register ↗Contractor Certificate of Registration (Dallas City Code Ch. 52), type Roofing (RO). This company appears on the city's own list of registered contractors. The city publishes no certificate number or expiry date for this programme, so ask to see the registration itself before work starts.
RegionProsper
Confirm this yourself: ask the company for their certificate of insurance (COI). Note that RCAT's Licensed Roofing Contractor credential (CRRL, RRL or CRL) is earned and held by a named individual at a company, not by the business itself, which is why we name that person above where we know it; Texas issues no company roofing license at all. RCAT and NTRCA status can be checked in their own public directories (RCAT, NTRCA) — use the "Licensed"/"Accredited" filter to see more than plain membership. GAF's contractor verification tool and Owens Corning's Texas locator confirm those tiers directly; CertainTeed doesn't offer a comparable self-serve lookup, so ask to see that certificate in person. BBB accreditation and rating are on bbb.org. Houston's own published registered-roofer list is years out of date, so it isn't cited here at all — confirm registration by contacting the city directly. Corpus Christi's STAR program has its own online contractor registry — for any other city or county registration claim, confirm directly with that jurisdiction's permit office.

Frequently asked
Does Texas issue a state roofing licence?
No. There is no state roofing licence in Texas, so no Prosper or Collin County roofer can be state licensed for roofing. Verify a contractor through insurance, city registration where required, BBB standing and manufacturer or association credentials you can check yourself.
Is Designer Roofing an RCAT member?
No record for Designer Roofing was found via a search of the RCAT contractor directory, so neither RCAT Membership nor the separately earned Licensed Roofing Contractor credential can be reported here. Most Texas roofers are not RCAT members, so this is not a mark against the company.
What is the difference between an RCAT Member and an RCAT Licensed Roofing Contractor?
Membership means the company pays dues to the Roofing Contractors Association of Texas. The Licensed Roofing Contractor credential (CRRL, RRL or CRL) is earned separately through experience and examination. A company can be a Member without holding the credential, and the two should never be treated as the same thing.
Are the GAF Master Elite and Owens Corning credentials confirmed?
The company displays both badges on its own About page. Neither could be independently confirmed on a GAF or Owens Corning contractor directory profile during this research, so treat them as company stated. If they matter to your decision, ask the company for its contractor ID and check it on the manufacturer's own verification page.
What is Designer Roofing best known for?
Metal. The company says it is one of the few contractors in the Metroplex with crews experienced in residential metal roofing, and that it keeps one dedicated team for stone coated steel and another for standing seam.
Why is hail the main roofing issue in Prosper?
Prosper sits in the North Texas hail belt, where spring storms regularly bring stones large enough to bruise asphalt shingles and dent metal panels. Much of that damage is not visible from the ground, which is why a post storm inspection matters more here than in most parts of the country.
Do impact resistant Class 4 shingles help in Collin County?
Class 4 is the top rating in the UL 2218 impact test and many Texas insurers offer a premium discount for a Class 4 roof. Ask your carrier for its specific discount before choosing, because the saving over the roof's life often covers a large part of the upgrade.
How does a metal roof hold up to Texas hail?
Metal generally resists puncture well but can dent cosmetically. Standing seam and stone coated steel behave differently, and some insurers treat cosmetic denting differently from functional damage. Ask both your contractor and your insurer how cosmetic hail damage is handled before you commit.
Do I need a permit for a roof replacement in Prosper?
Texas has no statewide building code, so permitting and inspection are handled town by town. Prosper and neighbouring Collin County cities generally require a permit for a re-roof. Get it in writing who is pulling the permit and confirm it with the town before work starts.
What should I ask before signing a roofing contract in North Texas?
Ask for a certificate of insurance sent directly from the insurer showing general liability and workers compensation. Ask who pulls the permit, whether the crews are employees or subcontractors, how long the workmanship warranty runs, and whether the manufacturer warranty is the standard one or an extended system warranty. Remember that a contractor paying or waiving your deductible is illegal in Texas.
