Hail Damage in Central Texas: Why Every Commercial Roof and Building Facade Should Be Professionally Assessed

Texas is no stranger to severe hailstorms. From Austin and Central Texas to Dallas–Fort Worth, Houston, and surrounding communities across the state, hail events can produce millions of dollars in property damage within minutes. While obvious damage such as broken windows or punctured roofing can be easy to identify, many of the most expensive problems begin with damage that is difficult, or impossible, to see from the ground. A professional assessment by professional engineers and/or IIBEC certified roofing professionals can identify damage which may be needed to support or deny insurance claims.

Why Central Texas Buildings Are Especially Vulnerable

The combination of intense thunderstorms, large hail, high winds, and prolonged UV exposure makes Texas one of the most demanding environments for commercial building exteriors. After a significant hailstorm, damage may occur to:

Low-slope membrane roofs

Modified bitumen roofing

Built-up roofing systems

Metal roof panels and standing seam roofs

Asphalt shingles

Roof-mounted mechanical equipment

Metal wall panels

EIFS and stucco systems

Fiber cement siding

Exterior insulation systems

Window frames and glazing

Sealants and waterproofing joints

Gutters and downspouts

Canopies

Edge Metal

Some damage is immediately visible. Much of it is not.

Not Every Dent Means Replacement is Necessary

One of the biggest misconceptions after a hailstorm is that every dent or impact requires replacement. Conversely, another common mistake is assuming that because a roof “looks fine,” it suffered no damage. The reality lies somewhere in between. A proper evaluation distinguishes between cosmetic and functional damage, considers whether damage may shorten the service life of the roofing or façade system, and separates hail event related conditions from pre-existing conditions. This distinction is critical when making repair decisions or presenting an insurance claim.

Hidden Damage Can Cost Thousands Later

Even relatively small hailstones can compromise roofing materials in ways that are not immediately apparent. Examples include:

Fractured membrane reinforcement

Cracked protective coatings

Bruised insulation beneath roof membranes

Displaced flashing

Damaged sealants around penetrations

Coating fractures on metal roofing

Displaced reflective granules on asphaltic shingles and membranes

Microcracking in stucco or EIFS

Water intrusion pathways that develop months after the storm

These conditions may not leak immediately. Instead, hail damage can accelerate deterioration of materials. Compromised materials can allow moisture to enter the building envelope, leading to mold, corrosion, interior damage, and expensive repairs that could have been avoided through early detection.

Why Assessment by Qualified Professionals Matter

Roofing contractors play an important role in repairing damaged roofs, but an independent engineering/roof consultant assessment provides an objective evaluation focused on the building’s performance rather than simply recommending replacement. A professional engineer or building envelope consultant can evaluate whether hail caused functional damage, determine the extent of damage across the property, and assess the remaining service life of affected roofing components. The evaluation can also help distinguish storm-related damage from age-related deterioration, inform repair-versus-replacement decisions, and provide documentation suitable for insurance claims or litigation. Our reports provide detailed photographs, measurements, damage mapping, and technical opinions supported by accepted engineering principles.

Don’t Forget the Building Facades

Many property owners focus exclusively on the roof after a hailstorm. However, building facades often experience significant damage that goes unnoticed. Hail impacts can damage:

Stucco finishes

EIFS systems

Metal panels

Architectural coatings

Masonry sealants

Window glazing

Curtain wall systems

Exterior flashing and trim

Water entering through damaged facade components may not become visible until months after the storm. A complete post-storm assessment should evaluate the entire building envelope, not just the roof.

Timing Matters

Insurance policies often include deadlines for reporting storm damage. Waiting too long may make it difficult to distinguish hail damage from normal aging or subsequent weather events. Early documentation can provide better evidence of storm-related damage, support more accurate repair recommendations and insurance claim evaluations, and establish a baseline for future monitoring if immediate repairs are not necessary. Even if no repairs are ultimately required, knowing the condition of your building provides valuable peace of mind.

Incomplete Building Envelope Designs Leave Building Owners with Costly Repairs

Walker Consultants — Fri, 29 May 2026 18:30:03 +0000

*Human Written Content

St. Louis, MO. – In cities like St. Louis, rainfall, temperature swings, and prolonged moisture exposure constantly test exterior materials, turning small enclosure vulnerabilities into costly restoration issues.

In humid coastal, urban, and inland environments, hidden envelope vulnerabilities can lead to widespread water intrusion years after construction.

So, what’s the problem?

Moisture-related issues are often discovered long after water has already penetrated the building.

That small stain you walk past every day has already traveled through your building’s envelope, hitting multiple areas that have yet to reveal themselves.

That brisk draft you feel might just be an early sign that your building envelope is no longer performing as intended.

Left unresolved, building envelope issues can affect indoor comfort, material performance, and air quality for those within the building.

Better Designs, Better Buildings, Better Solutions

Some of the most expensive building envelope failures begin after construction is complete and everyone assumes the envelope will perform as designed.

Many failures do not start with major storms or structural damage. They often start with one missed flashing detail. One failed sealant joint. One poorly designed transition between materials.

At Marina Place, a seven-story condominium building in Dunedin, Florida, just off the Gulf of Mexico, residents experienced significant water intrusion. Water was dripping from the middle of the ceilings and along the perimeter of the exterior wall onto the floor.

Walker’s investigation uncovered cracked stucco, failed sealant joints, and deteriorating façade conditions that allowed moisture to move deep into the building enclosure. What appeared to be isolated leaks had already spread through multiple exterior assemblies. When these transitions are overlooked, moisture rarely stays where it first enters.

Managing the flow of air, heat, and moisture begins long before occupancy. It begins with design.

When roofs, foundations, and vapor control layers are not designed to work as one system, moisture often finds the weakest connection first.

By the time signs appear inside, the damage may already be far beyond the point of a simple repair.

What can you do?

It is important owners take proactive measures to prevent water intrusion.

This includes diligent maintenance and strategic structural planning, regular inspections of roofs, basements and plumbing systems, and making sure the building envelope is properly sealed and waterproofed.

Long-term envelope performance depends on how water is managed from the beginning.

Roofs must drain quickly.
Standing water that stays on a roof for more than 48 hours can break down roofing membranes, find hidden imperfections, and accelerate failure.

Exterior walls need drainage, not just sealant.
Wall cladding sheds most rainwater, but some moisture always moves behind the surface.

Routine inspections of drains, flashings, seams, and roof penetrations help prevent moisture from entering the building in the first place.

When flashing, sealants, or drainage planes fail, water can become trapped inside the wall assembly, leading to mold, corrosion, and interior leaks.

Foundations should move water away from the structure.
Poor site grading, clogged drains, or damaged waterproofing membranes can allow water pressure to build against foundation walls.

Material transitions matter most.
Many envelope failures happen where systems meet.

Roof to wall
Wall to window
Wall to foundation
Slab to exterior wall

That pressure often pushes water through cracks, joints, or below-grade transitions and can also lead to failures in the foundation.

These intersections are often where moisture finds its first opening.

In a city like St. Louis, built on historic masonry and exposed to constant seasonal swings, long-term building performance often depends on how well the enclosure manages moisture over time.

FISP Made Easy: Our QEWI-Led Team for NYC DOB FISP is Here to Guide You

Walker Consultants — Wed, 12 Feb 2025 21:29:24 +0000

When it comes to compliance and safety, we are prepared to deliver prompt and effective solutions to building owners’ needs. Our experienced and responsive QEWI-led team will guide you through the Façade Inspection Safety Program (FISP) from New York City Department of Buildings.

FISP Cycle 10 Has Started.

What is a QEWI? What do they help with?

A Qualified Exterior Wall Inspector (QEWI) is a registered design professional (ex. Registered Architect or Professional Engineer) that meets a certain level of experience and qualifications, set by the New York City Department of Buildings (DOB), to inspect a building and assess the condition. Obtained through the New York City Department of Buildings Facades Unit, each QEWI is approved by the DOB to perform the façade inspection and complete the façade report filing for the NYC FISP.

While many design professionals may be experienced with both designing and assessing various façade assemblies across the country, the QEWI certification from the City of New York requires local professionals to submit documentation of at least 7 years of professional experience in performing New York City façade inspections. Also, it requires a working knowledge of numerous types of existing historic and modern masonry and other exterior enclosures to ensure that unsafe and deteriorated façade conditions are correctly identified, prioritized, and repaired.

Walker’s QEWI is Your Guide

Sara Holcomb, PE, a QEWI, in our New York City office, has worked on numerous façade inspection and restoration projects across the five boroughs of New York City. Catering to commercial, residential, hospitality, and historic properties, she is well-equipped to offer strategic advice, detailed project management, and expert oversight. Our QEWI’s expertise can help your building’s exterior comply with DOB standards.

The History of the Façade Inspection Safety Program

The Façade Inspection Safety Program (FISP) façade ordinance originated out of NYC legislation intended to protect the public health and safety from the risks of falling and deteriorated façade materials, due to aging building stock in New York City.

The New York City Department of Buildings (DOB) first instituted a façade-related inspection ordinance, referred to as Local Law 10 in 1980, when a piece of masonry debris fell and killed a pedestrian on the Upper West Side of Manhattan. Later amended and known as “Local Law 11”, the ordinance mandated maintenance and necessitated buildings to be classified as either “Safe”, “Safe with a Repair and Maintenance Plan (SWARMP)” or Unsafe. Over the last 44 years, well-publicized façade failures and resulting tragedies involving fatalities or injuries have expanded the complexity and strictness of these inspections and report filing requirements surrounding the NYC façade ordinance.
