Alvin's housing and storm record, read for replacement
Half of the homes in Alvin were built before 1985 (U.S. Census Bureau, American Community Survey 2020-2024), and 61% of homes are lived in by their owners. That mix means many roofs are on a second or third cycle, and many owners are deciding for the long term rather than for a quick sale.
The storm record matters too. NOAA's Storm Prediction Center logged 4 hail reports of 1.75 inches or larger within 10 miles of Alvin from 2015 through 2024, all of them in 2024. The biggest stone measured 2.75 inches on May 31, 2024. Hail that size can break the shingle mat across a whole slope. When damage is spread wide like that, patching one area at a time stops making sense.
There is also the question of the parts you do not see. On a house that is about 41 years old, the decking may be original plywood or boards that have soaked up decades of humidity. A replacement is the one moment when that wood is exposed and can be checked board by board. Skipping that step means the new shingles sit on a weak base.
Signs the roof has reached the end
Granule loss everywhere
Bare, dark patches across many slopes mean the shingles no longer block the sun or shed water well.
Curling and cracking
Edges that cup up or split are a sign of age and heat, not a single storm.
Soft spots underfoot
Decking that flexes when walked on has likely absorbed water for some time.
Repeat leaks
New leaks in different rooms after each repair point to a roof that is failing as a whole.
How a full replacement runs
Inspection and estimate
The roof, attic and decking are checked, and you get a written estimate that lists materials and scope.
Material choice
Asphalt shingle, metal, stone-coated steel or tile, each with its own weight, look and lifespan. Our guide to how long roofing materials last in Texas compares them.
Tear-off
Old layers come off down to the decking, and the yard is protected from nails and debris.
Deck repair and underlayment
Rotten boards are replaced, then new underlayment and flashing go down before the first shingle.
Final walk-through
The crew cleans up, runs a magnet sweep for nails and reviews the finished roof with you.
Before you sign anything
Ask whether the price includes decking repair, and at what rate if extra boards are needed.
Confirm which shingle line and underlayment are written into the contract.
Ask how ventilation will be handled; see how roof ventilation protects your home.
If hail is part of the story, a hail damage inspection in Alvin should come first.

Frequently Asked Questions
Can I put new shingles over the old ones in Alvin?
Some codes allow a second layer, but a tear-off is usually the better choice. It lets the crew see and replace rotten decking, and it avoids extra weight on the framing. On homes built decades ago, what is under the old shingles is often the part that needs the most attention.
Does a Class 4 shingle make sense near the coast?
Shingles rated UL 2218 Class 4 resist impact better than standard ones. Given the 2.75 inch hail recorded near Alvin in 2024, many owners consider them. Ask your insurance agent whether your policy treats impact-rated roofs differently before you choose.
What happens if rain comes during the job?
Crews tear off only what they can dry in the same day and keep tarps ready. If weather turns, the open section is covered with underlayment or tarps until work can continue. Ask how your contractor handles this before the job starts.
