Hail, often regarded as a silent destroyer, can wreak havoc on our properties, particularly roofs. Understanding hail damage and how to address it effectively ensures the longevity and robustness of your property. In places like Columbia Maryland, where roofing demands can be unique, having insights into hail damage becomes even more crucial. Here’s an in-depth guide by Kanga Roof that takes you through spotting hail damage, techniques to prevent it, and best practices to repair it.

1. Spotting Hail Damage: The Telltale Signs

a. Granule Loss

One of the initial and most visible signs of hail damage on asphalt shingles is granule loss. If you’re in Columbia MD and notice a significant amount of roofing granules in your downspouts and gutters, it’s a potential indication of roof damage.

b. Bruising

Not all damages are immediately evident. Sometimes, hail leaves behind a soft spot, akin to a bruise. Running your hand over the shingle can help detect these soft spots.

c. Cracks

Hailstorms, especially in regions like Columbia Maryland, can cause circular cracks on your roofing materials. This type of damage compromises the integrity of the roof, demanding immediate attention.

d. Exposed Roofing Layer

Once the granules have been pounded off and the fiberglass mat underneath is exposed, water infiltration is inevitable. This calls for swift rectification by roofing companies in Columbia MD.

e. Metal Damage

Inspect metal roof vents, flashings, and skylights. Hail damage often manifests as dents on these metal structures.

2. Preventing Hail Damage: Proactive Measures for Roof Safety

a. Invest in Impact-Resistant Roofing

Opt for Class 4 impact-resistant roofing materials. These materials undergo rigorous testing and can withstand the force of hailstones without sustaining damage. Consulting with a roofer in Columbia MD, such as Kanga Roof, can provide specific recommendations.

b. Regular Maintenance

Routine inspections, especially by roofing contractors in Columbia, help in early detection, enabling you to take preventive actions before minor damages morph into major issues.

c. Proper Installation

The role of professional installation in minimizing hail damage cannot be overstated. Ensure that the roofing materials are appropriately aligned and secured.

d. Gutter Guards

Installing gutter guards not only prevents clogging but also reinforces the gutters, making them more resilient against hail impacts.

e. Tree Maintenance

Trim overhanging branches. Falling branches can exacerbate the damage caused by hail.

3. Repairing Hail Damage: Ensuring Roof Longevity

a. Professional Assessment

Always engage a licensed contractor to assess the extent of the damage. Kanga Roof, for instance, offers comprehensive solutions tailored to your roof’s specific needs.

b. Patching and Replacing

Minor damages can often be patched. However, significant damages might necessitate shingle replacement.

c. Address Water Damage

Water infiltration, a fallout of hail damage, can compromise the structure. It’s imperative to replace wet insulation and repair interior leaks promptly.

d. Ensure Proper Ventilation

Post-repair, ensure the attic is adequately ventilated to prevent moisture build-up, which can lead to mold and weaken the roof structure.

e. Insurance Claims

Document the damage, procure repair estimates, and liaise with your insurance provider to ensure your claim is processed swiftly and adequately.


Hail damage, while unavoidable, isn’t insurmountable. By understanding its manifestations, adopting preventive measures, and ensuring timely repairs, you can safeguard the structural integrity of your property. Remember, a proactive approach today can save substantial costs and hassles tomorrow. Protect your investment with knowledge and timely action, and always consider the expertise of trusted roofing companies in Columbia MD.
