Ice dams are one of the most common and most preventable sources of roof and interior water damage in Northwest Indiana. Every winter, Lake County and Porter County homeowners deal with ice dam damage that could have been avoided with the right roofing system and attic conditions.
What Is an Ice Dam and How Does It Form?
An ice dam is a ridge of ice that forms at the edge of your roof (the eave) and prevents snowmelt from draining properly.
Here’s the process:
1. Heat from your living space escapes through inadequate attic insulation and warms the roof deck
2. Snow on the warmed upper portion of the roof melts and flows down toward the eave
3. The eave extends beyond the exterior wall and is not warmed by the house — it stays at outdoor temperature
4. The snowmelt refreezes at the cold eave, forming a ridge of ice
5. More snowmelt backs up behind this ridge
6. Water has nowhere to go but under your shingles — into your decking, insulation, walls, and ceilings
In Northwest Indiana, where lake-effect snow events can deposit 12-18 inches of wet, dense snow and temperatures oscillate through freezing repeatedly, ice dams form regularly on homes with any heat loss vulnerability.
Professional inspection ensures no damage goes undetected
The Warning Signs You Have Ice Dam Issues
- Icicles hanging from your gutters — large, impressive-looking icicles are often a warning sign
- Water staining on your attic rafters near the eaves
- Wet or darkened insulation near the eave line
- Water dripping from your soffits or fascia during a warming period
- Interior ceiling staining near exterior walls

Quality materials and expert installation make the difference
The Three Solutions — In Order of Importance
Solution 1: Attic Insulation (Most Important)
The root cause of most ice dams is heat escaping through inadequate attic insulation. If your attic is insufficiently insulated, the fix isn’t on your roof — it’s in your attic.
The minimum insulation level for our climate is R-38. The ideal is R-49 to R-60. Many older Lake County and Porter County homes have R-19 or less.
💡 Pro Tip
Schedule a professional inspection within 30 days of any major storm. Early detection prevents costly repairs down the road.
Improving attic insulation is often the highest-value investment you can make against ice dam formation — more effective dollar-for-dollar than any roofing modification.
Solution 2: Attic Ventilation (Equally Important)
Proper attic ventilation keeps your roof deck uniformly cold by replacing warm air that collects in the attic with cold outside air. A properly ventilated attic eliminates most of the differential temperature that causes ice dams.
The ventilation system needs both intake (typically at soffits) and exhaust (typically at ridge). Many homes have one but not the other — or both are blocked by insulation or debris.
Alamo Roofing assesses and corrects ventilation on every roofing project. Inadequate ventilation voids your GAF warranty and causes premature shingle failure — it’s not something we skip.
Solution 3: Ice and Water Shield (Essential Installation Component)
Ice and water shield is a self-adhesive membrane installed beneath your shingles at the eave line and in valleys. When ice dams back water up under your shingles, ice and water shield prevents that water from penetrating into your decking.
It doesn’t prevent ice dams — but it prevents the damage they cause.
Standard building code in Indiana requires ice and water shield at eaves. We install it at a minimum of 24 inches from the interior wall (further than code minimum) and in all valleys. This is standard on every Alamo Roofing project.
What to Do If You Already Have an Ice Dam This Winter
Do not: Attempt to remove ice with a sharp tool, use heat guns or open flame, or chip at the ice aggressively — these cause more damage than the ice dam itself.
Safe steps:
– Use a roof rake (long-handled tool) to remove snow from the lowest 3-4 feet of your roof — this removes the fuel source
– A professional can use steam (not heat guns) to carefully remove severe ice dams
– Address active interior water intrusion first — contain water, protect belongings
After the winter: Have Alamo inspect your attic insulation and ventilation. Repeated ice dam formation is a symptom of an underlying problem that needs to be corrected.

How Much Does a New Roof Cost in Will County, Illinois? (2025 Pricing Guide)
Will County, Illinois homeowners in Mokena, New Lenox, Homer Glen, Joliet, Lockport, Plainfield, and Romeoville face different roofing cost factors than their neighbors in Cook County or Indiana. This guide gives you accurate 2025 pricing for your area.
The Short Answer for Will County
- Asphalt shingles: $10,500 – $24,000
- Metal roofing: $20,000 – $36,000
- Average Will County home: 1,700–2,400 sq ft | 19–27 roofing squares
Will County homes — particularly in the fast-growing communities of New Lenox, Mokena, and Homer Glen — tend to be larger than Lake County Indiana homes, which pushes the average cost higher.
Why Will County Costs Are Different from the National Average
National roofing cost calculators typically use an average that doesn’t reflect:
– Local labor rates: Will County labor runs slightly higher than rural Indiana markets
– Home sizes: Will County’s newer suburban developments have larger footprints and more complex rooflines
– Permit costs: Will County municipalities each have their own permit fee schedules
– Material transportation: Materials delivered to western Will County suburbs carry slightly higher delivery costs
Material Pricing in Will County
GAF Architectural Shingles
The dominant residential choice in Will County. Most New Lenox, Mokena, and Homer Glen homes use GAF Timberline HDZ or equivalent — running $95-$135 per square for materials. Full system cost including all accessory products: $155-$215 per square.
Impact-Resistant Shingles
Will County sits in a documented high-frequency hail corridor. Class 4 impact-resistant shingles cost $25-$45 more per square but can qualify for insurance discounts that partially offset the premium. Worth discussing at your estimate.
Metal Roofing
Growing in Will County’s premium communities. Standing seam systems run $375-$625 per square installed.
Will County Permit Information
Each Will County municipality manages its own building permits for roofing:
– Will County Land Use Department: (815) 774-7940

How Long Does a Roof Replacement Take? What Northwest Indiana Homeowners Should Expect
One of the most common questions homeowners ask before scheduling a roof replacement is straightforward: how long is this going to take?
The honest answer requires a few distinctions — but for most Lake County and Porter County homes, the installation itself is a single day.
The Installation Day
A standard residential roof replacement — single-family home, 20-25 squares, moderate pitch — is typically completed in one day by an experienced crew.
What happens that day (in order):
– Crew arrives 7-8 AM with materials (often delivered the day before)
– Tear-off of existing shingles begins — typically 2-3 hours for a single layer
– Decking inspection and any necessary repairs
– Ice and water shield and underlayment installation
– Shingle installation — typically 4-6 hours for a standard home
– Ridge cap, pipe boots, and flashing details
– Cleanup and magnetic roller pass
– End-of-day walkthrough — typically 4-6 PM departure
What Makes Projects Take Longer
Larger homes (30+ squares): May extend to 1.5-2 days depending on complexity.
Steep pitches (9/12 or higher): Reduces crew pace and requires additional safety setup. Victorian homes in Valparaiso or older Crown Point neighborhoods with 10/12+ pitches may take 2 days.
Two-layer tear-off: Removing two existing shingle layers takes significantly longer than single-layer tear-off. Add 2-4 hours minimum.
Significant decking replacement: If extensive decking damage is discovered during tear-off, material procurement and installation adds time.
Complex rooflines: Multiple dormers, valleys, skylights, and custom flashing details slow installation pace. A relatively small but complex roof may take as long as a large simple one.
Weather disruption: Active precipitation stops work. If rain begins during installation, crews pause and cover exposed areas until it passes. This occasionally pushes completion to a second day.
Timeline From Estimate to Completion
The full project timeline — from your first call to completed installation — typically runs:
Free inspection: Same week, often same or next day
Estimate provided: Same day as inspection or within 24 hours
Material order and delivery: 3-7 days after contract signing
Permit approval: 3-10 business days (varies by municipality)
Scheduled installation: Depends on current backlog — typically 2-4 weeks during normal season, 4-8 weeks during peak storm season (May-August)
Storm damage emergency situations: We prioritize emergency tarping for active leaks within hours. Permanent repair/replacement scheduling depends on demand volume — during major storm events affecting multiple communities, scheduling may extend.
What You Can Do to Speed Up Your Project
- Have your shingle color and material selection ready before signing — this eliminates back-and-forth
- Make sure the permit can be pulled immediately — Alamo handles this but needs a signed contract first
- Be available or have someone reachable on installation day for any questions
- Have the property prepared (vehicles moved, landscaping protected) so the crew can start without delay
What to Tell Your Family
Installation day is noisy, starts early (7-8 AM), and involves continuous activity around the perimeter of your home. Plan accordingly for:
– Children with early school schedules
– Work-from-home meetings
– Pets sensitive to noise or activity
