Ice Dam Prevention in Clarksville, TN
Ice dams are a winter nightmare. Water backs up under your shingles, drips into your attic, and
ruins your ceilings. And they are preventable. In Clarksville, where we get freeze-thaw cycles
every winter, ice dams are common.
We have been xing ice dam damage in Clarksville since 2003. Our freeze-thaw cycles are
perfect for ice dam formation. Warm attic. Cold eaves. Melting snow. It is a recipe for disaster.
We have repaired ice dam damage on homes o Fort Campbell Blvd, near the Red River, and
in the historic district.
This article covers ice dam prevention in Clarksville. What causes them. How to stop them.
And what to do if you already have one. Call (931) 666-1469 for a free inspection.
What Causes Ice Dams on Clarksville Homes
Let us explain the science. Heat from your living space rises into your attic. That heat warms
the roof deck. Snow on the upper part of your roof melts. The water runs down to the eaves.
The eaves are colder because they overhang the outside wall. The water freezes. It builds up.
Water backs up behind the ice dam and seeps under your shingles.
The root cause is heat loss from your living space. Poor attic insulation. Air leaks around light
xtures, attic hatches, and plumbing vents. Inadequate attic ventilation. If your attic is warm,
you will get ice dams.
Ice dams are common in Clarksville because we have frequent freeze-thaw cycles. A warm day
(35-40 degrees) melts snow. A cold night (20-25 degrees) freezes it. Repeat. This is worse than
a sustained deep freeze because the melting and refreezing creates more ice.
Homes with low-slope roofs (4/12 or less) are most vulnerable. Also homes with complex roof
lines (valleys, dormers). Also homes with poor insulation. Also homes where the attic hatch is
not sealed.
Fort Campbell families, base housing has had ice dam problems in the past. We have repaired
many. The housing office now requires ice shield on all base roofs.
A: Our full package (inspection, gutter cleaning, minor repairs, ventilation check) is $250. Free
inspection only is free.
How to Prevent Ice Dams (Step by Step)
Prevention is cheaper than repair. Here is what you need to do.
- Improve attic insulation. Add insulation to at least R-38 (12 to 14 inches of berglass or
cellulose). This keeps heat in your living space, not your attic. If you have less than 6 inches,
add more. Cost is $1,000 to $2,000 for a typical attic.
- Seal air leaks. Caulk gaps around light xtures (recessed lights are a major source), attic
hatches, plumbing vents, and wiring penetrations. Warm air rises through these gaps. Use
spray foam or caulk. Cost is $200 to $500 if you DIY, more if you hire a pro.
- Improve attic ventilation. Ridge vents and so t vents keep the roof deck cold. Cold deck
means snow does not melt unevenly. Add ridge vents if you don't have them. Clear so t vents
of insulation. Cost is $400 to $800.
- Install ice shield underlayment. When you replace your roof, install ice shield 6 to 8 feet
up from the eaves. This is code in Montgomery County. It prevents water from backing up
under shingles. Cost is included in a new roof.
- Clean your gutters. Clogged gutters trap water and ice. Clean them in fall and after any
winter storm. Cost is $100 to $200 if you hire us.
- Install heated cables. For problem roofs, heated cables along the eaves melt channels for
water to drain. Cost is $300 to $600 installed. They plug into a GFCI outlet. Turn them on when
snow is forecast.
- Remove snow from your roof. Use a roof rake to pull snow o the lower 3 to 4 feet of your
roof after a heavy snowfall (more than 6 inches). Do not climb a ladder in winter. Do not use a
shovel (damages shingles). Cost is $200 to $400 for a professional snow removal service.
How We Fix Ice Dam Damage (Step by Step)
If you already have an ice dam, call us.
- Inspection. We look for icicles (long icicles indicate ice dams), ice buildup in gutters,
water stains in the attic, and damaged insulation. We use a moisture meter.
- Ice removal. We use steam or hot water to melt the ice dam. No chipping. No chemicals.
No pressure washer. We have a commercial steamer. Cost is $300 to $800.
- Leak repair. We remove damaged shingles and underlayment. We replace with new ice
shield and shingles. We make sure the ice shield extends at least 6 feet up.
- Ceiling repair (referral). We do not do drywall, but we can refer you to a contractor. Water
stains on ceilings may need painting or replacement.
- Prevention recommendations. We assess your insulation and ventilation. We give you a
written report with recommended improvements.

Frequently Asked Questions
Are ice dams covered by homeowners insurance?
Yes, typically. Water damage from ice dams is a covered peril. But you pay your deductible. Prevention is cheaper than your deductible. A $500 insulation upgrade can prevent a $2,000 claim.
Can I remove an ice dam myself?
No. Do not chip ice (damages shingles). Do not use salt or calcium chloride (damages shingles and kills plants). Do not use a pressure washer (damages shingles). Call a professional. We use steam.
How much does ice dam removal cost?
$300 to $800 depending on severity. We use steam. No damage to shingles. The cost may be reimbursed by insurance if the ice dam caused a leak.
Do heated cables prevent ice dams completely?
They help. They melt channels for water to drain. But if you have severe heat loss, you still need insulation and ventilation improvements. Heated cables are a supplement, not a solution.
How long does ice shield last?
Ice shield is a rubberized membrane that lasts as long as your roof (15 to 20 years). It is installed under the shingles. It does not degrade from UV because it is covered.
Can I install ice shield on an existing roof?
No. Ice shield goes under the shingles. You would need to tear o the shingles to install it. That is a full roof replacement. If your roof is old, consider replacing it.
