Signs Your Madison Roof Is Near the End: Granule Loss and More
Most Madison roofs don't fail all at once. They wear out over three or four years, one slope at a time, and the homeowner notices somewhere in the middle. This is how to read the signs from the ground, the gutter and the attic, so you know whether you're looking at two more winters or twelve. Roof granule loss is the first thing to check.
Start with the date
A shingle roof in Dane County lasts 18–25 years. If yours went on before 2006, it's in the window regardless of how it looks. If it went on before 2001, it's past it. The permit history on the City of Madison's website, or your suburb's, will tell you the date if you don't know it. So will the shingle itself: a bundle wrapper in the garage rafters, or the thickness and style compared with a neighbor's newer roof.
Roof granule loss: what the gutters tell you
Go out after a rain and look in the gutter, or at the splash block under the downspout. Shingles shed granules slowly all their life and fast at the end. A quarter inch of coarse black sand in the gutter of a 20-year-old roof means the shingles are down to the asphalt, and asphalt without granules dries, cracks and lets water through within a couple of seasons. This is one of the most reliable signs, and it's free to check.
Silver maple seeds and oak leaves in the same gutter mean it's been overflowing, which brings us to the eaves.
What the eaves tell you
Madison roofs die at the eaves first. Ice dams sit on the first three feet above the wall every winter, and after ten or fifteen winters the shingles there are lifted, the underlayment is torn and the decking is soft. From the ground, look for:
- Shingles along the bottom edge that look wavy or lifted rather than flat
- Fascia boards that are stained, peeling or pulling away
- Gutters that have been bent down by ice and never re-hung
- A roof edge that sags between the rafters
If the eaves are going but the field is fine, that's sometimes a repair. If the eaves are going on a roof over 18 years old, it's usually the beginning of the end, because the same heat loss that made the dams has been cooking the shingles from underneath all summer.
What the south and west slopes tell you
The slope facing south takes the sun; the slope facing west takes the wind and the hail. On an aging roof, those two slopes go first. From across the street with binoculars, compare them with the north slope. Bald black patches, a mottled look where granules are thin, shingles curling up at the edges or cupping in the middle — on the south or west but not the north — mean the roof has about two to three years left. When the north slope catches up, it's done.
Curling matters more here than in warm places. A curled edge is where wind gets under the shingle and where ice gets into the seam. Every spring storm takes a few more.
What the attic tells you
Go up with a flashlight on a bright day. Pinpoints of daylight through the deck mean the shingles are gone in those spots. Dark stains on the underside of the deck in more than one area, especially along the eaves and the valleys, mean the roof has been leaking quietly for a while. Frost on the nail tips in winter means the attic isn't ventilated, which is why the roof is aging faster than the wrapper promised. Roof ventilation Madison attics lack is the reason so many 2000s roofs are done at 18.
Repairs as a sign
If you've had a roofer out three times in two years for three different spots — a boot, then a valley, then a flashing — the roof is telling you something. Each of those repairs was probably right. Together they mean the whole thing is at the age where the next weak point fails every season. Patching a tired roof is buying time at a bad price; the repair versus replacement post goes through that math.
Things that look bad but aren't
Black streaks running down the north slope are algae, not failure. They're ugly, they don't shorten the roof's life much, and they can be cleaned. Moss is worse because it holds water and lifts shingle edges in freeze-thaw, but a light growth on a young roof is a maintenance job. A single missing shingle after a windstorm on a 10-year-old roof is a $300 repair. Slight color differences between slopes on a roof under 15 years old are just sun.
How the signs show up, season by season
Spring. After the snow melts, look for shingles lifted along the eaves, granules piled at the downspouts, and stains that appeared over the winter. This is when ice damage shows.
Summer. On a hot afternoon, curled or cupped shingles stand out on the south slope. After storms, check the yard for pieces.
Fall. With the leaves down, it's easy to see the roof from the street. Compare the slopes and look along the ridge line for dips.
Winter. Watch where the icicles form and where snow melts first. Bare patches on a snowy roof on a cold day mean heat is escaping through the attic in that spot.
Questions to ask a roofer about remaining life
- How many winters do you think this roof has, and why?
- Which slope is in the worst shape?
- Is the decking soft anywhere?
- If I fix it now, what should I expect to fix next?
- What would a replacement cost today?
What the end means for your budget
A roof doesn't fail on a date. The useful question is when to start planning. If two of the checklist items below apply, get a replacement price now and start setting money aside; the ranges for most Madison houses are on the cost page. If the roof is still sound but past 15, a look each spring costs little and catches ice damage before it reaches the decking. And if you're selling within a couple of years, a written report on the roof's condition, with a price, gives buyers a number instead of a guess.
Mistakes to avoid
Judging the roof from the front only. The front may face north and look fine while the back slope is bald.
Climbing up to check. An aging roof is slippery and brittle; binoculars and the attic tell you enough.
Reading a warranty as a lifespan. A 30-year or lifetime label describes the warranty, not how long shingles last under Dane County ice.
Ignoring the attic. Poor ventilation is why many roofs here wear out early, and a new roof over the same attic ages the same way.
If the roof has a few years left
Use them well. Fix the small things that let water in — a boot, a lifted eave shingle, a gap at the chimney — and keep the gutters clear so ice doesn't build at the edge. Air-seal and insulate the attic, which slows the wear and helps the next roof last longer too. Then book a spring look each year until the answer changes.
The honest checklist
Two or more of these and it's time for replacement pricing:
- Installed before 2006
- Heavy granules in the gutters
- Bald or curling shingles on the south or west slope
- Wavy, lifted or soft eaves; a history of ice dams
- Stains in more than one place in the attic
- Three repairs in two years
- A second layer of shingles already up there
One of them and it's time for a look. A standalone roof inspection with a written report usually runs $150–$300; ask whether the fee is credited if you hire that roofer. It should tell you, with photos, roughly how many winters are left. Better to hear "three more years, fix the boot" now than "it's done" next March with water in the bedroom. The roof replacement page has what a new one includes and costs.
