Michiana homeowners have an overwhelming amount of tasks before winter starts each year—rake the yard, prep the garden, check your tires, stock up on emergency supplies, unpack winter clothes, replace the winter clothes that inevitably no longer fit—on and on.
But there’s one item you don’t want to miss on your list: prepping your roof and gutters. Your roof faces three major threats during Indiana winters: Ice dams that force water under shingles, gutter damage from heavy ice loads, and water damage from repeated freeze-thaw cycles.
At Equity Roofing, we’ve helped thousands of Indiana and Michigan homeowners make sure their roofs and gutters are ready to take on winter. And today, we’re passing along the same advice we’ve given to them over the years.
In this article, we’ll walk you through exactly what to inspect, clean, and upgrade to ensure your roof and attic are fully winter-ready. By the end, you’ll be ready to take on your prep list like a pro.

When Should I Prep My Indiana or Michigan Home for Winter?
Indiana and Michigan homeowners should finish winter prep between early October and mid-November. During this time, the weather is still nice enough to work safely on your roof. You'll also beat the first big freeze.
Waiting until December or January means you're gambling with your home's protection. Once ice and snow settle on your roof, many preventive measures become difficult to complete. Ice makes roof work hazardous even for professionals. What could have been a simple fall repair becomes an expensive winter emergency.
What Should I Check on My Roof Before the First Snow?
Surface Issues and Nail Pops
Indiana and Michigan have big temperature changes that create "nail pops." This happens when nails push up through your shingles because the shingles expand and contract. Hot summers and freezing winters make this problem worse.
Each exposed nail becomes a leak point during freeze-thaw cycles. As snow and ice go through repeated melting and refreezing, water finds these tiny openings and seeps into your home. What starts as a barely visible nail head in the fall can become a steady drip in your ceiling by January.
What to Check on Your Roof For Winter
| What to Look For | Why It Matters |
| Missing, lifted, or curling shingles | Exposes underlayment and decking to water damage during freeze-thaw cycles |
| Visible nail heads or “pops” | Water can enter through nail holes, causing leaks and ceiling stains |
| Granules collecting in gutters | Indicates shingle aging and loss of protective coating |
| Rust or gaps in flashing | Creates leak paths around chimneys, vents, and valleys |
| Old or failed patch jobs | May not hold through heavy snow or ice storms |
Once you’ve completed your roof inspection, it’s time to move your attention to your gutters.
What Happens if I Don’t Clean My Gutters Before Winter?
Clogged gutters become ice traps that destroy your gutter system and damage your roof edge. Homeowners in snowy states should clean their gutters of all debris, including leaves, twigs, and shingle granules. These granules, washed from aging shingles, mix with other debris to create concrete-like dams when frozen.
The attachment strength of your gutters becomes critical in winter. Ice can weigh hundreds of pounds per section–far more than gutters are designed to hold continuously. When gutters aren't properly secured to your fascia boards, this weight will pull them completely off your house. The damage extends beyond just losing gutters; falling ice-filled gutters can damage siding, windows, and landscaping below.
Check for:
- Firm attachment using appropriate hangers spaced correctly for your gutter type
- Loose screws and bent brackets
- Downspouts that send water at least 6 feet away from your house (frozen water near your foundation can crack it and flood your basement when it melts)
It may not be the most thrilling house chores, but keeping healthy gutters is certainly one of the most important.
How Can I Prevent Ice Dams on My Roof?
Proper attic insulation and ventilation help to prevent ice dams on Michiana roofs. Ice dams form when heat escaping through your attic melts the snow on your roof. The water refreezes at cold eaves, creating a dam that forces water under shingles.
You may have an issue with your attic's insulation or ventilation system if you notice the following:
- Uneven snow melt patterns on your roof
- Ice is forming at the edges of your roof while snow remains higher up
- High heating bills despite constant furnace operation
- Cold spots in upper-floor rooms
Checking your attic before severe winter weather hits can help keep the issues at bay.
Keeping a Well-Insulated Attic
For Indiana homes, your attic insulation should have:
- R-value above 48
- At least 16 inches of blown cellulose insulation
- Even coverage with no thin spots
What's R-value? It measures how well insulation stops heat from escaping. The higher the number, the better it works.
How Much Insulation Do You Need?
| Insulation Type | R-Value per Inch | Recommended Depth (for R-48) | Notes |
| Blown Cellulose | R-3.2 | ~16 inches | Common in Indiana and Michigan homes; affordable and effective |
| Fiberglass Batt | R-3.0 | ~16 inches | Must be evenly laid; gaps reduce efficiency |
| Spray Foam (Closed Cell) | R-6.0 | ~8 inches | High cost, but provides superior air sealing |
| Mineral Wool | R-3.7 | ~13 inches | Fire-resistant; good soundproofing |
| Loose-Fill Fiberglass | R-2.5 | ~19 inches | Settles over time, requires occasional topping off |
Insulation squishes down over time. What started as 24 inches might become 20 inches after a few years. This makes it less effective, so you need to check it regularly.

How to Check Your Attic's Airflow
Good airflow in your attic stops moisture buildup and keeps your home's temperature steady.
Look For:
- Blocked vents (sometimes covered by insulation)
- Clogged vents on your roof ridge
- Bathroom fans that blow into the attic instead of outside
The IBHS shares in-depth strategies for preventing costly roof damage from ice dams. If you find problems with your attic's airflow, call a professional roofer to check it out.
What Should I Do for My Indiana or Michigan Roof Before Winter?
There are plenty of tasks a homeowner can safely do themselves for their roof’s winter preparation. We’ll cover the best items for homeowners to do, and when it’s best to call a professional for help.
Safe Homeowner Tasks:
- Clean gutters from a sturdy ladder
- Inspect roof from ground with binoculars
- Check attic insulation depth if safely accessible
- Clear soffit vents and document damage with photos
Trimming Tree Branches
Tree damage is a big risk for Indiana and Michigan homes, but you can prevent it. Branches hanging over your roof become really dangerous in winter when they're heavy with snow and ice. Even healthy branches can break and damage your shingles or poke holes in your roof.
Trim These Branches:
- Branches hanging directly over your roof
- Limbs that could reach your roof when heavy with snow
- Dead or sick branches
- Branches that already touch your house
The trick is fixing these problems before winter arrives. Once snow piles up on branches, it's too late to trim them safely.
When to Call a Professional Roofer:
- Your roof is over 15 years old
- You had leaks last winter
- You can see nail pops or missing shingles
- You don't know about your attic insulation or airflow
- You need any work done in winter (ice makes it too dangerous)
Professional roofers check everything: shingles, gutter security, insulation, airflow, and your roof's structure.
If your roof is 15 years old or older, winter prep becomes even more important. Older roofs have dealt with years of Indiana weather. The protective coating has washed off shingles. Metal flashings might have small gaps. Sealants around vents and chimneys have probably dried out and cracked.
These old parts might work fine in nice weather, but winter stress can turn small problems into big ones. That's why professional checks are so important for older roofs—trained experts can spot problems you might miss.
