Central Texas Hail Season Is Coming: How to Prepare Your Roof, Siding & Windows

Understanding Central Texas Hail Season

Central Texas sits in one of the most active hail corridors in the United States. The I-35 corridor from San Antonio through Austin, Temple, and Waco sees significant hailstorms multiple times per year, with the peak season running from March through June. Bell County, McLennan County, and Williamson County consistently rank among the highest in Texas for hail-related insurance claims.

Hailstones can range from pea-sized (quarter inch) to softball-sized (4+ inches) in severe supercell thunderstorms. Even "ordinary" hailstorms producing quarter to golf ball-sized hail cause significant damage to roofing, siding, windows, and painted surfaces. A single severe storm can damage every exterior surface of your home simultaneously.

The difference between a $500 insurance deductible and a $15,000 out-of-pocket expense often comes down to preparation. Homes with well-maintained exteriors and properly documented pre-storm conditions have smoother, faster insurance claims. Homes with deferred maintenance face disputes about whether damage was storm-caused or pre-existing.

Preparing before storm season is not about preventing hail damage — nothing stops a golf ball-sized hailstone. It is about minimizing damage severity, maximizing insurance coverage, and getting your home restored quickly after a storm hits.

Pre-Storm Roof Inspection Checklist

Your roof is the largest and most exposed surface on your home, making it the most vulnerable to hail damage. A pre-storm inspection identifies existing issues that could worsen during a storm and documents your roof's condition for insurance purposes.

From the ground (use binoculars): Look for missing, cracked, or curling shingles. Check for visible granule loss (bare spots on shingle surfaces). Inspect flashing around chimneys, vents, and skylights for gaps or lifting. Check that ridge cap shingles are intact and seated.

Gutter check: Clean gutters and downspouts to ensure proper drainage during heavy rain. Check for excessive granule buildup in gutters, which indicates aging shingles. Verify that downspouts direct water at least 4 feet away from the foundation.

Attic inspection: Look for daylight coming through the roof deck, which indicates missing shingles or deteriorated underlayment. Check for water stains on rafters or decking that suggest existing leaks. Verify that attic vents are clear and functional.

Document everything with dated photographs. These "before" photos become invaluable if you file a storm damage claim, establishing that your roof was in good condition prior to the hail event. A professional roof inspection from a GAF Certified contractor like Glacier Home Exteriors provides documentation that carries weight with insurance adjusters.

Siding, Windows, and Paint Pre-Storm Checklist

Siding inspection: Walk all four sides of your home looking for loose, cracked, or warped siding panels. Vinyl siding with existing cracks will shatter more extensively in a hailstorm. James Hardie fiber cement with chipped areas exposes the substrate to moisture. Repair or replace damaged panels before storm season when possible.

Check all caulking and sealant around windows, doors, and penetrations. Failed caulk joints allow wind-driven rain to enter wall cavities during storms, causing hidden moisture damage that compounds the exterior impact. Recaulk any gaps or cracked joints with a high-quality polyurethane sealant rated for Texas temperature extremes.

Window inspection: Test all windows for proper operation — they should open, close, and lock smoothly. Check weather stripping for deterioration. Inspect glass for existing cracks or seal failures (fogging between panes). Damaged windows are more vulnerable to storm pressure and wind-driven debris.

Storm windows and screens: If you have storm windows, verify they are properly secured. Remove torn or damaged window screens — they become wind-borne debris in severe storms and provide no protection against hail.

Exterior paint condition: Peeling, cracking, or chalking paint leaves wood and substrates exposed to moisture penetration during storms. Areas where paint has failed are significantly more vulnerable to water damage when hit with heavy rain and wind. If your paint is failing, addressing it before storm season prevents compounding damage.

Photograph all exterior surfaces with date stamps. Walk each side of the house and take wide-angle photos plus close-ups of any existing blemishes. This documentation distinguishes pre-existing conditions from storm damage in insurance claims.

Emergency Supplies and Insurance Preparation

Emergency supply list for storm season: Keep heavy-duty tarps (at least one 20x30 tarp per 1,000 sq ft of roof) in your garage or storage building. Stock plywood sheets sized to cover your largest windows. Keep a battery-powered weather radio and flashlights with fresh batteries. Maintain a supply of sandbags or sand tubes if your property has drainage concerns.

Additional supplies: roofing cement and a caulk gun for emergency patching, duct tape for temporary repairs, a waterproof camera or smartphone for immediate post-storm documentation, your contractor's emergency contact number posted where you can find it.

Insurance policy review: Pull out your homeowner's insurance policy and review it before storm season, not after a storm hits. Confirm your deductible amount — many Texas policies have separate wind/hail deductibles that are higher than the standard deductible. Common hail deductibles are 1-2% of the home's insured value, meaning a $300,000 home could have a $3,000-$6,000 hail deductible.

Verify your policy covers replacement cost, not actual cash value. Replacement cost pays to replace damaged materials with new equivalents. Actual cash value deducts depreciation, potentially leaving you thousands short of the repair cost.

Know your filing deadline. Texas law allows up to two years for weather-related claims, but filing promptly (within days of the storm) produces better results. Document storm events in your area even if you do not see obvious damage — some damage only becomes apparent during professional inspection.

Why a Pre-Storm Professional Inspection Beats Waiting

Most homeowners call for exterior inspections after a storm, when every contractor in Central Texas is overwhelmed with demand. Wait times of 2-6 weeks are common after major hail events. During that wait, exposed surfaces suffer ongoing water damage from subsequent rain, and temporary repairs may be inadequate.

Scheduling a comprehensive exterior inspection before storm season delivers several advantages. First, any existing damage or maintenance issues are identified and can be repaired at non-emergency pricing with normal scheduling. Second, the inspection creates baseline documentation that strengthens any future insurance claim. Third, if a storm does hit, you already have a relationship with a qualified contractor who knows your home and can respond quickly.

A pre-storm inspection should cover all exterior surfaces: roof, siding, windows, gutters, paint, and trim. At Glacier Home Exteriors, our inspectors evaluate every component and provide a detailed report with photos, prioritized recommendations, and cost estimates. As a GAF Certified roofing contractor and James Hardie Elite Preferred Contractor, we inspect and service all four major exterior systems.
