Most homeowners think of their roof as shingles. But the shingles are just the surface — the structural foundation they’re nailed into is your roof deck, and its condition directly affects whether your new shingles perform properly and last their rated lifespan.
What Roof Decking Is and Does
Roof decking (also called roof sheathing) is the structural panel material nailed to your roof rafters. Everything above it — underlayment, ice and water shield, shingles — is attached to it. It provides:
- underlayment, ice and water shield, shingles — is attached to it. It provides:
- Structural rigidity to the roof framing
- A nailing surface for all roofing components
- A substrate that transfers loads to the rafters
Decking integrity is fundamental. Soft, rotted, or damaged decking compromises shingle fastening and can allow further water infiltration even through a new roof.
Professional inspection ensures no damage goes undetected
OSB vs. Plywood — What’s the Difference?
Plywood: Multiple thin wood veneers bonded with adhesive, alternating grain direction. Stronger for its thickness, handles moisture exposure better than OSB, holds fasteners well even after some moisture exposure. Common in homes built before the mid-1990s.
OSB (Oriented Strand Board): Wood strands compressed and bonded with adhesive. More uniform in thickness, less expensive than plywood, and the dominant product in homes built since the mid-1990s. Performs comparably to plywood under normal conditions but is more sensitive to prolonged moisture exposure — edges swell and delaminate when wet.
In practice, both materials perform adequately under properly installed roofing systems. The meaningful difference shows up when moisture has been present — OSB failure from moisture exposure tends to be more visible and more complete.
How Decking Gets Damaged
Active roof leaks: Water infiltrating through failed shingles, flashings, or pipe boots saturates decking and causes rot or delamination over time. Even small leaks, if sustained, cause significant decking damage.
Ice dam water infiltration: Water backed up behind ice dams infiltrates below shingles and reaches the decking at the eave. This is one of the most common decking damage patterns in Northwest Indiana homes.
💡 Pro Tip
Schedule a professional inspection within 30 days of any major storm. Early detection prevents costly repairs down the road.
Condensation from inadequate ventilation: Moisture rising from the living space condenses on underside of cold decking in winter. Chronic condensation causes slow deterioration that may not be visible until full rot develops.
Original installation defects: Improper gap spacing during original installation can cause buckled panels when wood expands seasonally.
Quality materials and expert installation make the difference
How We Assess Decking During Re-Roofing
During tear-off, we walk the entire deck surface and assess:
- off, we walk the entire deck surface and assess:
- Any areas that feel soft or spongy underfoot
- Visual signs of staining, mold, or delamination
- Edge deterioration (common with OSB after moisture exposure)
- Any areas of obvious rot or structural compromise
We photograph every area of concern and show you before replacing anything. We charge by the sheet (4×8 panels) for replacement — you know the cost before we proceed.
We never replace decking that doesn’t need replacement. Our reputation depends on honest assessments, not padding job costs with unnecessary materials.

What Decking Replacement Costs
Standard OSB or plywood replacement: $85-$150 per sheet (4×8 panel) installed, depending on accessibility and location. Each sheet covers 32 square feet.
Original plank decking (older homes): Some Crown Point, Hammond, and older Portage homes have original solid-board plank decking. Replacing planks requires more time than panel replacement — typically $4-$8 per square foot.

The Red Flag: Multiple Layers on Old Decking
Indiana and Illinois allow a maximum of two shingle layers. Homes with two existing layers must have both removed before re-roofing. When we tear off two layers on an older home, we often find decking that hasn’t been inspected in 30-40 years. Budget for potential decking replacement on any multi-layer tear-off project — the likelihood is meaningfully higher than on single-layer projects.

How to Choose the Right Roof Color for Your Indiana or Illinois Home
Shingle color is the most visible element of your roof — and unlike the structural components, it’s a decision that’s essentially permanent for 25+ years. Getting it right matters. Getting it wrong is expensive to undo.
Here’s how to make a confident color decision for your Lake County or northern Illinois home.
The Variables That Affect How Color Looks
Your home’s permanent colors: Brick color, stone color, trim color, and any cladding that won’t change with the roof are your fixed reference points. These don’t change — your roof color needs to work with them.
Undertones matter more than base color: Many Lake County homes have red-orange brick. A roof described as “gray” may have blue undertones that clash with warm brick, while a gray with brown undertones complements it perfectly. Always evaluate undertones in natural light before deciding.
Daylight vs. shade: Shingles look different in full sun than in shade, and different in morning light than afternoon light. If possible, look at the color sample at different times of day.
Neighborhood context: Your roof is visible to neighbors and passersby. Consider what’s common in your neighborhood — not to blend in identically, but to avoid standing out awkwardly.
Matching by Home Style and Exterior
Brick homes (very common in Hammond, Oak Lawn, and older Lake County neighborhoods):
– Red-orange brick: Charcoal, weathered wood, brown tones, or slate (avoid cool grays with blue undertones)
– Buff/cream brick: Almost anything works — charcoal, brown, slate, or lighter gray
– Dark brick: Lighter charcoal or weathered wood for contrast; avoid very dark shingles that lose definition
Vinyl or fiber cement siding homes (common in Schererville, St. John, New Lenox):
– White or light gray siding: Charcoal, slate, or dark brown for contrast and definition
– Tan/beige siding: Brown tones, cedar blends, or weathered wood
– Blue-gray siding: Charcoal or slate with complementary undertones
Cedar or wood-look homes:
Weathered wood, cedar blend, or brown tones enhance the natural aesthetic. Avoid high-contrast dark charcoal unless you’re specifically going for a modern look.
Stucco homes: Neutral gray tones or brown tones work well. Stucco’s smooth texture benefits from a shingle color that doesn’t compete.
The Most Popular Choices in Our Market
Based on installation patterns across Lake County and northern Illinois:
Charcoal: The most universally popular choice for the past decade. Works with nearly any exterior, provides good contrast against most wall colors, and doesn’t show dirt or staining as visibly as lighter colors.
Weathered wood (brown/gray blend): Popular on traditional and craftsman-style homes. Warm undertones work well with brick and wood-tone siding.
Barkwood: A warm brown-gray that’s particularly popular on tan or beige-sided homes throughout the area.
Slate: A blue-gray option that works well with gray or white siding and contemporary home styles.
Energy Efficiency Consideration
Dark shingles absorb more solar heat. In our climate — where heating costs exceed cooling costs — the conventional “dark shingles increase cooling costs” concern is less significant than in southern markets. However, if energy efficiency is a priority, lighter shingle colors or specifically designed cool-roof shingles are available.
How to Visualize Before You Decide
GAF’s Roofing Visualizer: GAF’s online tool allows you to upload a photo of your home and virtually try different shingle colors. This is genuinely useful for narrowing options.
Physical samples in natural light: Never make a final decision from a color chip in a brochure or on a computer screen. Request physical shingle samples and hold them against your home’s exterior in natural daylight.
Drive your neighborhood: Look at installed roofs on similar homes in your area. This gives the best real-world reference for what different colors actually look like at full scale.

12 Questions to Ask Before Signing Any Roofing Contract in Indiana or Illinois
Signing a roofing contract without asking the right questions is how homeowners get surprised by costs they didn’t expect, warranties they can’t enforce, and work that doesn’t meet the standards they thought they were paying for.
These 12 questions — asked before signing, in writing — protect you.
1. What exactly is included in this price?
“Roof replacement” means different things to different contractors. A complete answer includes: tear-off, disposal, underlayment type, ice and water shield scope, drip edge, all flashings, and cleanup. Ask for a line-item breakdown if the estimate is summarized.
2. What shingle brand, product, and color will be installed?
This should be in the contract verbatim — not just “architectural shingles.” Get the GAF product name, the specific shingle line, and the color. Material substitution is a real practice; a specific written specification is your protection.
3. What happens if you find damaged decking under my shingles?
Ask specifically: How is decking replacement priced? Per sheet? Per board? Will you show me what needs replacing before you replace it? A legitimate contractor has a clear, documented policy. Vague answers about “extras as needed” are red flags.
4. Will you pull all required permits?
The permit should be pulled and posted before work begins. Ask specifically: “Will you pull the permit before crews arrive?” If they say permits aren’t necessary or suggest you can skip them — walk away.
5. What certification level do you hold with your manufacturer?
Not “are you certified” — but specifically what level. GAF Master Elite, GAF Certified, Owens Corning Platinum Preferred, CertainTeed SELECT ShingleMaster. The level determines what warranty you can receive. Verify it independently at the manufacturer’s website.
6. What exactly is covered by the warranty — and who backs it?
Three separate answers needed: material warranty (from manufacturer, how long, what’s covered), workmanship warranty (from whom — contractor or manufacturer, how long), and what voids each coverage.
7. Are you licensed in Indiana AND Illinois (if applicable)?
If you’re in Illinois: ask for their IDFPR roofing license number and verify it at idfpr.illinois.gov. An Indiana license does not cover Illinois work. Unlicensed contractors cannot legally pull Illinois permits.
8. Can I see your current insurance certificate?
Ask for an actual certificate of insurance — not just a verbal confirmation — showing general liability AND workers’ compensation with current dates and your property as a certificate holder. This protects you.
9. What is the payment schedule?
Standard practice: a deposit at contract signing (typically 10-25%), balance at project completion after your inspection and approval. Any contractor requiring more than 50% upfront is a red flag. Full payment before work begins or before completion is a red flag.
10. Who specifically will be supervising my project on installation day?
Get a name. Ask about their experience. Know who to contact if you have questions during the day. Accountability requires a specific person.
11. How long will this take, and what’s my start date?
Get a realistic timeline in writing — expected installation date, projected completion, and what happens if weather delays occur. “Sometime next month” is not acceptable.
12. What is your process if I have a problem after the work is completed?
Ask specifically: Who do I call? What’s the response time commitment? What does your warranty claim process look like? A contractor who’s vague about post-completion service is telling you something.
