Roof Granule Loss in Clarksville, TN

We see granule loss every day in Clarksville. Our summer heat bakes shingles. Our spring

hailstorms knock granules loose. Our humidity accelerates degradation. Homes o Tiny Town

Road that are 12 years old often have signi cant granule loss on the south and west slopes.

This article covers roof granule loss in Clarksville. What it looks like. What causes it. And what

to do about it. Call (931) 666-1469 for a free inspection.

What Granule Loss Means for Your Roof

Let us start with the basics. New shingles have a thick layer of granules. As the shingle ages,

granules loosen. You will see them in your gutters. A few granules are normal. A lot means

trouble. If you can ll a co ee can with granules from your downspouts, that is excessive.

When granules are gone, the asphalt underneath is exposed. UV rays from the sun break down

the asphalt. It becomes brittle. It cracks. Water gets in. The shingle fails. This process takes 2

to 3 years once granules are gone.

Granule loss also reduces re resistance. The granules are a re barrier. Without them, the

shingle is more ammable. This is rarely an issue in residential res, but it matters.

In Clarksville, granule loss accelerates after about 10 years. By year 15, many shingles are bald

on the south and west slopes. That is a sign that replacement is near. We have inspected

homes o Wilma Rudolph Blvd where the south slope was completely bald, but the north slope

looked ne.

Granule loss can be uneven. One slope may be bald while another looks ne. That is because

the sun hits some slopes harder. South and west slopes are worst. North and east slopes may

still have granules.

Fort Campbell families, if you see granules in your gutters, do not panic. But do get an

inspection. We can tell you if the loss is normal or excessive. We can also recommend partial

slope replacement if only one slope is a ected.

How We Assess Granule Loss (Step by Step)

1. Check your gutters. We look at the accumulation. A light dusting (a teaspoon per 10 feet

of gutter) is normal. A thick layer (a cup per 10 feet) means signi cant loss.

1. Check your downspouts. Granules collect at the elbows. We remove the downspout and

look. We also check the splash block or drain pipe.

1. Get on the roof. We walk the south and west slopes first. We look for bare spots (shiny

black asphalt). We run our hands over the shingles. If we feel smooth asphalt, the granules are

gone. If we feel roughness, granules remain.

1. Check the age of your roof. Granule loss is normal after 10 years. If your roof is 5 years

old and losing granules, that is a defect. The manufacturer warranty may cover it. We can help

you le a claim.

1. Check the rest of the roof. If one slope is bald but others are ne, you may only need to

replace that slope. We can do partial replacements. This saves money.

1. Recommend repair or replacement. Minor granule loss (less than 10% of the roof):

monitor. Moderate loss (10-30%): consider replacement in 2-3 years. Severe loss (more than

30% or any bald spots): replace now.

Why Hire Clarksville Roofing Co for Granule Loss?

We know the difference between normal aging and premature failure. If your roof is under

warranty, we can help you le a manufacturer claim. Premature granule loss is a manufacturing

defect. We have helped homeowners get free shingles from GAF and Owens Corning.

We also offer partial slope replacements. If only the south slope is bald, we can replace just

that slope. Cost is $800 to $1,500. That is much cheaper than a full replacement. The color

may not match perfectly, but it is a good budget option.

where your roof stands. We will give you an honest assessment.
