Cedar shingle installation requires material-specific knowledge that differs from conventional asphalt shingle installation. Cedar responds to moisture, airflow, and fastening differently, and installation errors may lead to premature performance issues, depending on the defect and exposure. Liberty Restoration Group put this guide together to explain what experience adds to a cedar project and what homeowners can look for when choosing a contractor.
Cedar Shingles vs. Cedar Shakes
The two terms are often used interchangeably, but they aren’t the same product. Cedar shingles are typically sawn on both sides, which gives them a smoother, more uniform appearance. Cedar shakes are usually split or split-and-resawn, which gives them a thicker, more textured look. The difference affects installation details, spacing, and appearance, so it’s worth confirming which material your project calls for.
What Experience Adds to a Cedar Shingle Roofing Project
Cedar isn’t complicated in theory, but it punishes shortcuts in ways that show up slowly. Someone with real cedar experience understands how the material needs to breathe, how it reacts to moisture, and what kind of fastening holds up over time versus what only looks secure on installation day.
Experience also means being able to look at an existing roof and spot problems before starting new work. A contractor with limited cedar experience might miss signs of rot in the decking underneath or overlook flashing that’s already failing, and end up installing new shingles over a foundation that isn’t ready for them.
There’s also the matter of understanding how everything on a roof works together. Ventilation, underlayment, flashing, and the shingles themselves aren’t separate decisions, because they affect each other. Treating them as independent tasks can lead to performance issues that develop later, when they may be more costly to address.
Common Cedar Shingle Roofing Problems Caused by Poor Installation
Many cedar roofing problems trace back to a handful of installation issues, and they’re worth knowing before you hire anyone.
- Shingles placed too tightly together, which doesn’t give the wood room to expand and can lead to buckling or cupping over time.
- Fasteners driven at the wrong depth or angle, which weakens the hold and can allow shingles to lift in high wind.
- Flashing installed with the wrong materials, insufficient laps, or poor transitions at chimneys, valleys, and other penetrations. Sealant alone isn’t a substitute for correct flashing, because flashing performance depends on how it integrates with the full roof assembly.
- Ventilation gaps that are too small or blocked entirely, which can trap moisture underneath the roof deck.
- Poor drainage or water concentration at valleys, transitions, penetrations, or other vulnerable details.
Any one of these on its own might not cause immediate failure, but they can compound. A roof with several of these issues may age faster than expected, and correcting problems later can cost more than addressing them during the original installation. This is part of why homeowners sometimes look for cedar shingle roofing contractors after a previous installation shows problems sooner than they anticipated.
Why Local Roofing Experience Matters in Chicagoland
Cedar has to perform in whatever the local climate brings, and Chicagoland’s mix of humid summers, cold winters, and seasonal transitions means a roof here goes through repeated expansion, contraction, and moisture cycling.
Contractors who have worked in this area for years develop familiarity with which installation details matter most locally, such as where winter ice tends to affect a roof, where ventilation concerns often show up, and how freeze-thaw cycles may influence fasteners over time.
Local requirements matter too. Building codes and permitting rules, including those covering fire ratings, ventilation, and structural load, can vary by municipality, so it’s worth confirming with your contractor how they handle the requirements where you live. Getting that wrong can mean failed inspections or rework. Homeowners with an aging roof may also find that a full evaluation of roof replacement services is worth considering when the original installation didn’t account for local conditions.
Matching and Compatibility When Repairing an Existing Cedar Roof
Repairing part of an existing cedar roof adds its own considerations. Replacement shingles should be compatible with the existing ones in species, grade, dimensions, and exposure, and the installer should account for how weathered the surrounding cedar is. New cedar will look different from aged cedar at first, and it will gradually blend in as it weathers. Repair details such as fastening, flashing integration, and ventilation should also be compatible with the existing assembly. An experienced contractor can explain what to expect from a repair and where a partial repair may have limits.
Natural Cedar vs. Premium Synthetic Shake Alternatives
Some homeowners also consider premium synthetic shake products. These can offer a similar profile with different maintenance, fire-rating, and warranty characteristics, but they’re a different material from natural cedar, with a different look, feel, and performance profile. A good contractor can walk through the tradeoffs of each option in relation to your home, budget, and priorities, without treating them as equivalent.
How to Compare Cedar Shingle Roofing Contractors
Comparing quotes on price alone can leave out important differences in scope and approach. Here’s a more useful way to compare contractors.
| What to Compare | Why It Matters |
| Cedar-specific project history | General roofing experience doesn’t transfer directly to cedar |
| Materials and installation method | Different approaches affect longevity and appearance |
| Warranty terms | Review coverage, exclusions, duration, transferability, and responsibility for repairs |
| Project supervision | Determines whether experienced crew members are actually on site |
| Estimate clarity | Vague estimates can lead to scope changes and added costs later |
A contractor with strong reviews for asphalt work isn’t automatically a good fit for cedar. It’s worth asking how many cedar projects they’ve completed recently and asking to see examples that are a few years old rather than fresh installs, since that’s when workmanship becomes easier to evaluate. Keep in mind that warranty terms define contractual protection. They don’t prove quality on their own.
What Homeowners Should Expect From an Experienced Roofing Team
A contractor who knows cedar tends to follow a similar process, even if the details of a project change.
| Stage | What a Good Contractor Does |
| Inspection | Thorough review of existing roof, deck, and problem areas |
| Explanation | Clear breakdown of findings and recommended work |
| Preparation | Proper prep of the roof deck and surrounding areas before installation |
| Installation | Careful attention to spacing, fastening, flashing, and ventilation |
| Communication | Regular updates throughout the project, not just at the start and end |
If a contractor moves straight to a quote without explaining their findings, it’s reasonable to ask for more detail. Cedar roofing services done well involve upfront diagnosis, and you should feel you understand what’s being recommended and why.

Frequently Asked Questions
1. How long should a properly installed cedar shingle roof last?
Lifespan depends on the installation, the grade of cedar, ventilation, exposure, and maintenance. Correct installation and regular upkeep give a cedar roof the best chance of performing well over the long term, while installation errors can shorten its service life.
2. Is cedar shingle roofing more expensive than asphalt in Chicagoland?
Cedar typically costs more upfront than asphalt because of material and labor requirements. Cost varies with the material grade, roof complexity, and scope of work, and many homeowners weigh it against appearance and long-term goals.
3. How can I tell if my current cedar roof was installed correctly?
Possible warning signs include uneven weathering, shingles that appear too tightly spaced, visible curling or cupping, and moss or discoloration appearing earlier than expected. A professional inspection is the most reliable way to evaluate installation quality.
4. Do cedar shingle roofs require special maintenance compared to other materials?
Cedar generally needs periodic cleaning, moss prevention, and inspection, particularly in humid or shaded areas of the roof. The right schedule depends on your roof’s exposure and condition.
5. What questions should I ask a roofing contractor before signing a cedar project contract?
Ask about their cedar project history, who will supervise the work on site, and the expected timeline. Also review warranty coverage, exclusions, duration, transferability, and who is responsible for repairs.
