What Size Hail Will Damage a Roof? A Washington Homeowner’s Guide

If you are wondering what size hail will damage a roof, you are not alone. Many homeowners across Washington ask this question after a strong storm passes through their neighborhood. While small hail may look harmless, even moderate hail can weaken shingles and reduce the lifespan of your roofing system.

In Washington, storms often combine wind driven rain, sudden temperature shifts, and seasonal hail events. These conditions can create more damage than hail alone. The real concern is not just the size of the hailstones, but how they impact your roof at high speeds.

At Builders Service Company, we specialize in full roof replacements. We do not perform minor repairs. If hail has compromised your roofing system, our team focuses on replacing the entire roof to ensure long term protection and structural integrity. Acting quickly after a hailstorm helps prevent deeper damage to your home.

What Size Hail Will Damage a Roof in Washington Storms?

Understanding what size hail will damage a roof in Washington depends on several factors including roofing material, age, and storm intensity. Below is a breakdown of common hail sizes and their impact.

Pea Size Hail (1/4 Inch)

Pea size hail often causes cosmetic damage. On newer roofs, it may not cause noticeable problems. However, on older asphalt shingles, even small hail can:

• Loosen protective granules

• Accelerate surface wear

• Weaken already aging materials

In Washington’s damp climate, a roof that is already nearing the end of its lifespan may become vulnerable even from smaller hail.

Marble to Penny Size Hail (1/2 to 3/4 Inch)

At this size, hail begins to cause more measurable damage. Combined with strong wind gusts, these hailstones can:

• Knock off granules

• Leave shallow dents

• Create weak spots in shingles

Granule loss is a serious concern because those granules protect shingles from UV exposure and water penetration. Once the protective layer is compromised, moisture intrusion can begin.

Quarter Size Hail (1 Inch)

Quarter size hail is commonly considered the threshold where noticeable roof damage occurs. In many Washington hail claims, this is the size that leads to replacement discussions.

Damage at this stage may include:

• Bruising of shingles

• Cracks that are not immediately visible

• Compromised underlayment protection

Bruised shingles may look intact but feel soft underneath. Over time, these areas break down and allow water infiltration.

Golf Ball Size Hail (1.75 Inches) and Larger

Golf ball size hail and larger stones often cause severe roof damage. At this level, homeowners may notice:

• Cracked or split shingles

• Broken flashing around vents and chimneys

• Exposed underlayment

When hail reaches this size, the likelihood of needing a full roof replacement increases significantly. Structural integrity becomes a concern, especially on older roofs.

What Size Hail Will Damage a Roof in Washington Based on Roofing Material?

The impact of hail also depends on the type of roofing installed. Not all materials respond the same way.

Asphalt Shingle Roofs

Asphalt shingles are common across Seattle, Tacoma, Olympia, Bellevue, and surrounding areas. They are durable, but hail can still cause:

• Granule displacement

• Soft spot bruising

• Reduced lifespan after impact

Even if leaks do not appear immediately, bruised shingles often fail within months or a few seasons.

Metal Roofing Systems

Metal roofing systems are more impact resistant. However, they are not immune.

Hail may cause:

• Surface dents

• Coating damage

• Compromised seams if impact is severe

While dents can appear cosmetic, coating damage can lead to corrosion over time if left unaddressed.

Composite and Premium Roofing Materials

Some composite roofing systems have higher impact resistance ratings. However, installation quality plays a major role. Poorly installed systems may fail even under moderate hail.

In hail prone zones across Western Washington, professional installation is essential for long term performance.

What Are the Signs of Hail Damage on a Roof?

Not all hail damage is obvious from the ground. Here are key indicators homeowners should look for.

Visible Exterior Signs

• Dented vents or flashing

• Random circular dark spots on shingles

• Granules collecting in gutters or downspouts

If your gutters are full of shingle granules after a storm, that is a warning sign.

Interior Warning Signs

• Water stains on ceilings

• Attic moisture or musty smell

• Sudden leaks following a storm

Interior damage often appears weeks after the hail event.

Subtle Structural Indicators

• Soft shingle texture when inspected

• Uneven or patchy roof appearance

• Premature aging across sections

These signs may indicate widespread impact that requires more than surface attention.

How Much Does Roof Replacement After Hail Cost in Washington?

One of the most common questions after understanding what size hail will damage a roof is cost.

Average Roof Replacement Costs in Washington

Roof replacement costs vary depending on size and materials. In Washington, typical residential roof replacement ranges between:

• 12,000 to 25,000 dollars for standard homes

• Higher for complex rooflines or premium materials

Larger homes in areas like Bellevue or custom properties in Gig Harbor may exceed these ranges.

Variables That Impact Cost

Several factors influence final pricing:

• Roof pitch and complexity

• Material choice

• Extent of structural damage

• Removal of existing layers

• Ventilation upgrades

A full system replacement ensures every layer is updated, not just surface shingles.

Insurance Considerations

Hail damage often qualifies for insurance coverage if it impacts structural performance. Documentation is critical.

Working with an experienced contractor helps ensure proper assessment and clear reporting of damage severity.

When Does Hail Damage Require Full Roof Replacement Instead of Repair?

At Builders Service Company, we focus exclusively on full roof replacements. We do not perform minor patch repairs.

Minor patching can:

• Create uneven wear patterns

• Shorten overall roof lifespan

• Lead to recurring leaks

Partial fixes may seem cost effective at first, but they often delay the inevitable. A complete system upgrade restores uniform protection and eliminates hidden weaknesses.

If hail has compromised multiple areas, full replacement provides long term peace of mind.

Frequently Asked Questions About Hail Damage in Washington

Can small hail damage a new roof?

Small hail may not cause visible cracks, but repeated impacts can weaken surface granules over time.

How soon should I replace my roof after hail damage?

If structural compromise is confirmed, replacement should not be delayed. Moisture infiltration can spread quickly.

Does hail always cause immediate leaks?

No. Many roofs appear fine initially. Damage often becomes visible weeks or months later.

Is cosmetic hail damage a problem long term?
