FAQ

No. Texas issues no roofing license at all -- the state licenses electricians, plumbers and air conditioning contractors, and has never licensed roofers. La Porte does not register them either, so there is no local list to check. What exists here instead is better suited to the question you are actually asking: a permit, a specification the roof has to meet, and a certification letter from a Texas licensed engineer or an ICC Certified Coastal Construction and Floodplain Inspector within 30 days of the permit issuing. That certificate describes your actual roof rather than the firm that fitted it.

In La Porte, yes -- a roof replacement needs a permit whether you are hiring somebody or doing it yourself. Texas has no statewide answer to this because permitting is municipal, which is why the question keeps getting answered badly online. Doing it yourself also does not exempt the roof from the specification: the 150 mph shingle requirement and the nails-not-staples rule apply to the roof, not to who fitted it, and the certification letter still has to reach the city inside 30 days.

In the Houston area most re-roofs run $7,500 to $16,500 in architectural asphalt, and a house with 2,000 to 2,500 square feet of roof area typically lands at $10,500 to $14,000. Per square foot that is $6.00 to $9.00 for architectural and $4.50 to $7.50 for three-tab. Coastal work sits toward the upper end of those ranges, because the fastening specification takes more labor -- not because the materials cost more.

For a standard asphalt roof on an average Houston-area house, yes -- that is roughly double the $10,500 to $14,000 most land at. It is not unreasonable for a large house, a complicated multi-plane roof, or a standing seam metal system, all of which exist in this service area. The number alone does not answer the question; what the quote itemizes does. If it does not break out area, perimeter, decking and the certification, you cannot tell.

On Houston-area rates, 2,800 square feet of ROOF in architectural asphalt works out at roughly $16,800 to $25,200, and rather less in three-tab. The trap is in the units: 2,800 square feet of floor is not 2,800 square feet of roof. Pitch, overhangs and dormers commonly make the roof area a third larger than the house area, which is the commonest reason two quotes look inexplicably far apart.

Nobody selling roofs is a neutral source on that, so here is what is actually known rather than a forecast. Roofing prices follow asphalt and steel input costs, freight, and local labor availability, and along this coast they spike for months after any significant wind event because demand arrives all at once. What that means practically is that the cheapest time to replace a roof is when you choose to, and the most expensive is the two weeks after half the neighborhood decides at the same time.

Not on age alone -- but on this coast there is a second question that matters more. A 20 year old architectural roof is middle-aged by material standards, so the usual tests apply: granule loss, brittleness, how flat the covering lies, whether the deck is sound. Then ask how it was fastened. A roof fitted 20 years ago may have been stapled, or nailed to a pattern that predates the current wind requirement, and on a bay-shore house that matters more than how the shingles look.

It is a Florida rule and it has no force in Texas. The 25% rule comes from the Florida Building Code Existing Building, where repairing or replacing more than a quarter of a roof within a year can trigger a requirement to bring the whole roof up to current code. Texas has no equivalent provision, and La Porte's requirements are set out in its own roofing policy instead. Anyone quoting the 25% rule at you in Texas is citing the wrong state's code book.
