Flat Roof Replacement in Shoreacres

Because wind uplift concentrates at edges and corners rather than in the middle of a roof. A membrane that is merely adhered starts to go there, and once an edge lifts the wind gets underneath and the rest follows quickly. Mechanical perimeter fixing is the design here, not an upgrade.

Not in itself -- water that clears within a day or two of rain is normal. Water still there a week later is a seam being tested continuously, and it usually means the fall does not actually run or the outlet is not at the low point.

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.

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.
