How did we pick these?
Houston is a city where the roof is the part of the house that fails, and the result set for this search is almost entirely companies grading their own homework. So we ignored every adjective and ranked on things a reader can verify in ten minutes.
Start with the fact that reframes the whole question. Texas does not license roofing contractors. Roofing is not on the Texas Department of Licensing and Regulation's list of regulated occupations, which runs to more than forty trades and does include air conditioning contractors and electricians. So the phrase "licensed and insured", which appears on nearly every Houston roofer's homepage, is close to meaningless, and we applied the same test here that we used on the Dallas roofing market.
What is checkable sorts the field fast:
- A published RCAT licence number, not just the logo. Two firms here print theirs.
- Manufacturer tiers. GAF Master Elite and the President's Club award above it, Owens Corning Platinum Preferred, CertainTeed.
- A founding year that something outside the company agrees with.
- A Houston-area street address that is not a mailbox or a landing page.
That ordering is why Amstill is first and Holden, despite a 1961 start and the top Owens Corning tier, is last: it publishes no street address for any of its seven offices.
What is different about Houston, and it is not hail. Dallas roofers sell against hail. Here the governing document is wind. TDI's own Harris County page puts La Porte, Morgan's Point, Pasadena, Seabrook and Shoreacres inside the designated catastrophe area where they fall inside the city limits and east of Highway 146, and structures built after dates in 1996 and 1997 need a WPI-8 certificate of compliance. That is a small slice of a very large county, but if you are in it, a roofer who already works inside the WPI-8 process is worth more than a better-reviewed one who does not. It is the single reason State Roofing is ranked second.
No business on this list is a client of ours and none paid for its place.

What should you know before you call?
Get three written quotes and make each one name the shingle line, the underlayment, the ventilation plan and the warranty tier. Two quotes that look $4,000 apart are often quoting different roofs.
Timing works against you twice a year. After a named storm every crew in the region is booked and out of town companies arrive to take the overflow, and in the deep summer tear-off work slows down because nobody can safely stay on a black roof all afternoon. The quiet windows are late autumn and late winter, which is also when you can get a crew that is not rushing.
If you are filing insurance, do not sign anything that assigns your claim to the contractor until you have read it twice. And photograph the roof and the attic before the crew arrives. Interior water staining is the evidence that settles arguments later.
What should you do next?
If you own a house inside the Loop or out along Memorial, call Amstill and ask for the RCAT number on the phone. If you are in La Porte, Seabrook, Pasadena or Shoreacres, call State Roofing first and lead with the WPI-8 question. If you manage a commercial building, it is Chamberlin, or R.B. Hash when the problem involves metal or slate.
