Roof replacement with six inch guttering on a home in Alvin Texas

Alvin sits twenty-one minutes east of us along SH 35, an older Brazoria County town with a proper historic core, established neighbourhoods around Alvin Community College, and newer building spreading out toward Manvel and Mustang Bayou.

It is also the answer to a trivia question that turns out to be a roofing specification. In July 1979, Tropical Storm Claudette stalled over Alvin and dropped 43 inches of rain in 24 hours, which remains the highest 24-hour rainfall total ever recorded in the United States. That happened here, on these streets, to these houses.

What a rainfall record means for a roof

It means the governing condition on an Alvin roof is water volume, and the components that handle volume are the ones worth spending money on:

  • Six-inch guttering, not five. Roughly 40 percent more capacity for about three dollars a foot. On this town's rainfall history that is not an upgrade, it is the correct specification.
  • Downspout count against roof area. The commonest fault after gutter size, and it produces identical overflow.
  • Membrane in every valley. Self-adhering ice-and-water rather than felt, because a valley is where two slopes' worth of water meets and a felt valley will find its limit.
  • Proper drip edge. Without it, water curls back under the shingle edge and runs behind the gutter permanently, which is how fascia rots on a house whose guttering appears to work.

Older housing stock, mixed exemption status

Alvin's age profile means a meaningful share of its housing predates January 1, 1988 and is therefore exempt from windstorm certification, unlike the newer towns up the 288 corridor where essentially nothing is. On any given Alvin street the house on one side may be exempt and the one opposite not. Checking the build date and the TDI certificate record before you plan a re-roof is genuinely worth the five minutes here.

Alvin is inside the windstorm programme

Alvin sits in Brazoria County, one of the fourteen first-tier coastal counties in the Texas Department of Insurance designated catastrophe area. A re-roof here must comply with the windstorm building code for the property to stay eligible for wind and hail coverage through TWIA, and the certificate that proves it earns a building code credit of 19% to 33% off the wind premium. Houses built before January 1, 1988 are exempt.

How the WPI-8 works and whether your house needs one.

Permits in Alvin

Alvin is incorporated and runs its own building department, so roofing permits go through the city rather than through Brazoria County. Different authority and different timetable from the unincorporated addresses around Rosharon and Damon, where the county Floodplain office in Angleton asks for up to twenty business days.

Maintenance matters more here

Given the rainfall profile, the annual maintenance visit is a better purchase in Alvin than almost anywhere else on our round: gutters cleared, downspouts checked, valleys inspected and penetrations resealed, at $225. May is the right month, before the season. What the visit covers.

Roofing questions from Alvin

Is it true Alvin holds the US rainfall record?

Yes. Alvin recorded 43 inches of rain in 24 hours during Tropical Storm Claudette in July 1979, which is still the highest 24-hour total ever recorded in the United States. It is a good reason to specify guttering and valley membrane properly rather than to the builder minimum.

Does an Alvin roof need windstorm certification?

It depends on the build date. Alvin is in Brazoria County, which is a first-tier windstorm county, so houses built on or after 1 January 1988 need a WPI-8 on a re-roof to keep TWIA eligibility. Alvin has a lot of older stock that is exempt, which is unusual for this service area.

Should I upgrade to six inch gutters in Alvin?

On almost any Alvin roof, yes. Six-inch carries roughly 40 percent more water than builder five-inch for about three dollars a foot more, and this town's rainfall history is the argument. The cheapest moment to do it is during a re-roof, when the guttering is off anyway.
