Signs Your Schaumburg Roof Is Near the End of Its Life
A roof does not fail on a schedule. It fails at the eave one February, at the valley the next spring, and at the chimney the winter after that, and by the third repair you have spent enough to wish you had replaced it. The signs that a roof is at the end are visible from the ground, the gutter and the attic a couple of years before the first leak. Here is what to look for on a Schaumburg house.
Age, adjusted for here
The shingle wrapper says 25, 30 or "lifetime." In the northwest suburbs, the honest numbers are 15–20 years for 3-tab and 22–28 for architectural, and less on a poorly ventilated attic. The stock in Weathersfield, Timbercrest, the Hoffman Estates parcels and the older parts of Palatine was largely re-roofed in the mid-1990s to mid-2000s, mostly with 3-tab, so a great many of those roofs are at the end right now. If you do not know when your roof went on, the village permit records or the previous owner's disclosure will say. If it has two layers, the top one is often 20-plus years old.
What you can see from the ground
Granules in the gutter
Clean the gutter or look at the splash block under a downspout. Some granules after a hailstorm or on a new roof is normal. A steady accumulation every time it rains — a handful in the gutter, a dark sandy pile at the downspout — means the shingles are shedding their UV coating, and the asphalt under it is about to go brittle. Bald patches you can see from the ground, especially on the south and west slopes, mean it already has.
Curling and cupping
Stand across the street and look at the roof against the sky. Shingle edges lifting at the corners (curling) or the middles dishing (cupping) mean the asphalt has dried out. Curled shingles do not lie flat, do not seal, and lift in the first 50-mph gust of spring. A roof that looks lumpy or wavy from the street is one where the shingles have curled or the decking underneath has sagged.
Cracked, brittle tabs
If a roofer can lift a shingle in September and it cracks, the roof cannot be repaired. This is the test we do on every estimate, and it is the point at which "we can fix that valley" becomes "the fix will leak at its edges."
The winter signs
Ice dams every year and the stain that goes with them. The stain along the eave line above an exterior wall that reappears each February is partly the roof — no ice-and-water shield — and partly the attic. Rusted nail tips and stained decking at the eave in the attic show the history. A roof that has been through ten ice dam cycles has had water under its bottom three courses ten times.
The attic signs
Go up with a flashlight on a bright day. Daylight through the deck at any point but the ridge vent and gable vents. Delaminating plywood, sagging between rafters, or planks with dark stains. A cluster of rusty nail tips. Insulation that is matted or discolored under any part of the roof. Any of these means the deck is taking water, and the shingles above it are not keeping it out.
The map of the roof
Some spots on a Schaumburg roof fail first, and they tell you how far the rest is behind:
| Spot | What you see | What it means |
|---|---|---|
| South and west slopes | Bald, curled, faded | Most UV; the rest of the roof is 3–5 years behind |
| Eave line | Lifted, stained, resealed shingles | Ice dam history |
| Valleys | Granule loss in a stripe, exposed mat | Snowmelt and ice sat here every winter |
| Around the chimney | Stained brick, mortar-in flashing | Flashing at the end, whatever the shingles are doing |
| Ridge | Cap shingles cracked or missing | The cap goes first in wind |
| Flat section on a split-level | Shingles on a low slope, ponding | Should have been a membrane to begin with |
Moss and dark streaks
Black streaks running down the north slope are algae, and on their own they are cosmetic. Moss along the bottom edge of the shingles holds water against them and lifts the tabs; on a 20-year-old roof it is a sign the granules are gone and the shingle is holding moisture. The moss and algae post covers what to do about them.
How many signs make a replacement
One of these is a repair. Two or three, on a roof over 18 years old, is a roof to plan around: budget, get an inspection with a written estimate of remaining life, and pick a season. Four or more, or any of them on a two-layer roof, and the next leak is the replacement; the money spent patching between now and then is gone. The repair-or-replace guide gives the decision rules and the prices.
Roofing Schaumburg IL homeowners put off because "it is not leaking yet" tends to get replaced in January, at the worst time and price. A roof that is showing three of these signs in September will very likely get you through the winter. Two winters is the gamble.
