If more than 20-25% of the shakes are splitting, cupping, or missing, repairs stop making financial sense. Widespread rot, soft spots in the decking, and interior leaks in multiple areas are signs the whole roof is done. A contractor can walk the roof and give you an honest read.

If your cedar shake roof is pushing 25 or 30 years old, you already know something is off. The shakes look rough, maybe there is moss creeping across the north slope, and you have had a couple of leaks you would rather not think about. The honest answer: most cedar shake roofs in Madison reach the end of their useful life somewhere between 25 and 40 years, depending on maintenance and weather exposure. When they go, they go fast.
This guide covers how to know you are actually there, what your replacement options look like, what things cost in the Madison market right now, and the one surprise cost that catches most homeowners off guard.
Signs Your Cedar Shake Roof Is Done
Cedar shake gives you plenty of warning before it fails completely. Here is what to look for from the ground and during any inspection.
Cupping and Splitting Shakes
Individual shakes curl up at the edges (cupping) or develop lengthwise cracks (splitting) as they age and dry out. A few here and there can be spot-repaired. When you see it across a whole slope, the roof is telling you it is done as a system.
Moss, Algae, and Rot
Moss holds moisture against the wood. In Wisconsin, where wet springs and humid summers are the norm, that moisture cycle accelerates rot. If you can press your thumb into a shake and feel it give, the wood fiber is compromised. Rot spreads to neighboring shakes and eventually to the decking beneath.
Missing Shakes and Material Loss
Cedar does not lose granules the way asphalt does, but it does shed material. Missing shakes after a wind event, or shakes that have thinned down to almost nothing, mean the roof has no redundancy left. One bad storm and you have a leak.
Interior Water Stains and Soft Decking
Water stains on your attic sheathing or ceiling drywall are a red flag. If a contractor walks your roof and finds soft or spongy spots, the decking below the shakes has already taken on moisture. At that point you are replacing the roof anyway, plus the decking.
If you are seeing two or more of these issues across a significant portion of the roof, repairs are throwing money at a losing cause. It is worth getting a proper inspection from a contractor who will tell you the truth.
Your Replacement Options (and What Each One Actually Means)
When a cedar shake roof comes off, you have three realistic paths forward. Each has a different cost, look, and long-term story.
Option 1: New Cedar Shake
Real cedar is beautiful. If you want the authentic look and feel of what came off, new cedar shake can go back on. The upside is obvious. The downside is maintenance, and it is real.
Cedar needs to be cleaned and treated with a preservative or fungicide every 3-5 years to prevent moss, mildew, and rot from taking hold again. In our experience, budget roughly $500-$1,500 per treatment cycle depending on roof size and who you hire. Skip that maintenance and you will be back in the same position in 15 years instead of 30. Finding installers who do cedar work well is also harder than it used to be, which affects both scheduling and price.
In the Madison market, new cedar shake sits at the high end of any estimate. It is not the most common choice anymore, but it is a legitimate one for the right homeowner who goes in with eyes open.
Option 2: Synthetic Shake
This is where most homeowners land when they want the cedar aesthetic without the maintenance headaches. Synthetic shake is made from engineered polymers or composite materials. The better products are nearly indistinguishable from real cedar at curb level and carry Class 4 impact ratings, the highest available under UL 2218 testing, which simulates large hail strikes.
South-central Wisconsin does see hail, and Class 4 impact resistance is worth considering here. Some insurance carriers offer premium discounts for Class 4 roofing, but this varies widely by company and policy, so check with your insurer directly before counting on it.
On maintenance: synthetic shake is not truly zero-maintenance, but it is close. You will not be treating it with preservatives every few years the way you would real cedar. That said, algae and debris can still accumulate in shaded areas, so an occasional rinse or soft-wash cleaning every several years keeps it looking right and prevents any organic buildup from shortening the life of the product.
One important note on warranties: synthetic shake products often advertise 40-50 year warranties, but the details matter. Many of those warranties are prorated, meaning the coverage value decreases significantly after the first 10-15 years. Read the fine print, or ask your contractor to walk you through what is actually covered and for how long.
The tradeoff is upfront cost. Synthetic shake runs more than architectural asphalt, though generally less than real cedar.
Option 3: Architectural Asphalt Shingles
Architectural (also called dimensional or laminate) asphalt shingles are the most common residential roofing material in Wisconsin for a reason. They perform well in our climate, carry solid warranties, and cost significantly less than either cedar or synthetic. Some architectural shingle lines are specifically designed to mimic a wood shake profile.
The aesthetic gap is real. Up close, they read as asphalt. But from the street on a typical residential lot, they hold up visually. For homeowners who prioritize performance and budget over replicating the exact cedar look, architectural shingles are a smart, honest choice.
Our residential roofing page covers shingle grades and options in more detail if you want to dig into the specifics.

What Cedar Shake Replacement Costs in Madison
These are realistic ranges for the Madison, WI market based on our experience with local projects. Your actual number depends on roof size, pitch, story height, decking condition, and which material path you choose.
- Architectural asphalt shingles (replacing cedar): $9,000-$16,000 for a typical 1,500-2,000 sq ft home, assuming some re-decking is needed.
- Synthetic shake: $15,000-$28,000 for the same home size range, depending on product line and complexity.
- New cedar shake: $18,000-$35,000+, reflecting higher material and labor costs.
These are not guarantees. They are honest ballpark numbers so you are not walking into a conversation blind. Get at least two or three written estimates with full scope spelled out.
Financing Options
A cedar shake replacement is a significant spend, and most homeowners are not writing a check for $20,000 out of pocket. Ask any contractor you are seriously considering whether they offer financing options. Many roofing contractors work with third-party lenders that offer fixed-rate installment loans, sometimes with promotional periods. If storm damage is involved, your insurance payout may cover a large portion, with financing bridging any gap. Do not let the sticker price push you toward a cheaper contractor who cuts corners. There are usually ways to make the right project work financially.
The Surprise Cost Nobody Warns You About: Spaced Decking
Here is the thing that catches a lot of Madison homeowners off guard. Old cedar shake roofs were frequently installed over skip sheathing, sometimes called spaced decking. Instead of solid plywood or OSB covering the entire roof surface, skip sheathing uses boards with gaps between them. Cedar shake does not need a solid deck the way asphalt shingles do, so this was standard practice for decades.
The problem: when you tear off the old shakes and want to install modern roofing materials, that spaced decking has to go. Wisconsin building code and manufacturer installation requirements both prohibit laying architectural shingles or most synthetic products over gaps. The new roof needs a solid, continuous substrate.
Re-decking with 7/16" or 1/2" OSB or plywood typically adds $1,500-$4,000 to the job in our experience, sometimes more on larger or steeper roofs. A contractor who does not mention this possibility upfront is either inexperienced with shake tear-offs or not being straight with you. Ask about it directly before you sign anything.
We have done enough cedar shake replacements in neighborhoods like Nakoma, Maple Bluff, and the older parts of Middleton to know that spaced decking is the rule, not the exception on homes from the 1970s and 1980s. Budget for it. If the decking turns out to be solid, that is a pleasant surprise.
If you are getting quotes for a roof replacement in Madison, make sure every estimate includes a line item for decking inspection and potential re-decking. Apples-to-apples comparison matters here.

What the Tear-Off Is Actually Like
A lot of homeowners ask what to expect during the job itself, and it is a fair question. Cedar shake tear-off is louder and messier than a standard asphalt-over-asphalt job. Old shakes are heavy, especially if they have absorbed moisture over the years, and getting them off the roof and into a dump trailer generates real noise and debris.
A good crew will lay tarps over your landscaping and shrubs before work starts to catch falling material. Your gutters should be protected or cleared out after tear-off so debris does not clog them. Expect some dust and vibration inside the house, especially on the top floor. Most homeowners find it manageable for a couple of days, but it is worth knowing ahead of time rather than being surprised.
Ask your contractor specifically how they protect your property during tear-off. Any experienced crew has a standard process for this. If they look at you blankly when you ask, that tells you something.

Insurance and Storm-Damaged Cedar Shake
Wisconsin weather is hard on cedar shake. Hail and high winds are the two most common causes of insurance claims on shake roofs, and Dane County sees its share of both over the course of a typical summer.
A few things to understand clearly before you call your adjuster:
Normal wear and aging are not covered. If your roof simply reached the end of its useful life, that is not an insurable event. Coverage applies to sudden damage from a specific covered peril, like a hail storm or a wind event. If a storm rolled through your neighborhood and you have legitimate impact damage or lifted shakes, that is a conversation worth having with your insurer. If the roof is just old and worn out, filing a claim is unlikely to go anywhere and could affect your rates.
ACV vs. RCV policies. Actual cash value (ACV) policies pay out the current depreciated value of your old roof. Replacement cost value (RCV) policies pay what it actually costs to replace it. On a 30-year-old cedar shake roof, the difference can be thousands of dollars. Check your policy before the adjuster arrives.
Having a contractor present helps. Adjusters are thorough, but they are also moving quickly across many claims after a storm event. Having a contractor on-site who knows what storm damage looks like on cedar shake can help ensure every impact point and wind-lifted shake gets properly documented. At Buckshot Exteriors, we meet your adjuster on-site to help with that documentation. What gets noted in that visit shapes the claim, so it is worth having someone there who knows the material.

Timeline: How Long Does Cedar Shake Replacement Take?
Most cedar shake replacements in the Madison area run 2-4 days once materials are staged. Add a day if re-decking is needed. Weather is a real factor in Wisconsin, especially in spring and fall, so experienced local contractors build schedule flexibility around the forecast. Your crew should not be tearing off a roof with rain in the forecast.

How to Choose the Right Contractor for This Job
Cedar shake tear-offs are more involved than a standard asphalt-over-asphalt replacement. The weight of old wet shake, the condition of skip sheathing, the need to properly flash valleys and penetrations on an older roof structure, these are not jobs for a crew that has never done one.
Here is what to actually verify before you hire anyone:
- Wisconsin contractor registration. Wisconsin requires roofing contractors to be registered with the Department of Safety and Professional Services. Ask for their registration number and look it up.
- Liability insurance and workers' comp. Get a certificate of insurance naming you as an additional insured. If a worker is hurt on your roof and the contractor is uninsured, you have a problem.
- Experience with shake specifically. Ask how many cedar shake tear-offs they have completed in the last two years. Ask to see photos or speak with a reference from a similar project.
- Written scope of work. Every estimate should spell out tear-off, decking inspection, re-decking allowance, underlayment spec, material brand and grade, flashing details, and warranty terms. Vague estimates protect the contractor, not you.
- Local presence. A contractor with a real local office and verifiable history in the area is accountable in a way that a traveling storm-chaser crew is not.
