The splash block under the north downspout is full of black grit again, and the warranty folder in the kitchen drawer still says thirty years. Grit like that is the roof itself, which is why the roofers mequon wi homeowners call ask about the shingle before they ask about the paperwork. The house in question is a mid-1990s two-story on a wooded lot, heavy afternoon sun on the south slope, shade and moss on the north, nineteen years on the current shingles, and one soft spot in the soffit that nobody wants to bring up. The argument here is simple. How much life is left in an asphalt roof is set by the condition of the shingle on each slope, not by the number printed on a warranty, and a homeowner who confuses the two ends up buying an emergency instead of a project.
The Warranty Clock And The Roof Clock Differ
A thirty year shingle warranty is not a thirty year guarantee that your roof will keep water out. It is a manufacturer’s document about manufacturing defects, and most of them prorate hard after the first decade, cover labor for only a short window, and say nothing at all about installation error, blocked soffit vents, or a hailstorm. Terms vary by manufacturer and by product line, so the only version worth planning around is the one with your product name on it. Pull it out and read the exclusions.
That language describes the shingle as it left the plant, tested under laboratory conditions. Your roof has been outside since 2007, through every February thaw and every July afternoon since. The number on the cover was never a service life; it was a rating.
Waiting also gets more expensive, and not only because a leak keeps working while you think. The National Association of Home Builders reported in June 2026 that government regulations at every level of government now add an average of $131,734 to the price of a new home, roughly 26.4% of the average sales price, a 40% jump from $93,870 in 2021. That figure is about new construction rather than reroofing, so nobody should read it as a quote. Read it as the direction of travel on anything built or installed, which matters when the replacement conversation on a house this size lands in the low five figures.
Granules In The Gutter Outrank Any Warranty Date
Granules are the shingle’s sunscreen. Once they are collecting in the splash block by the cupful, the asphalt underneath is cooking in the open.
So walk the perimeter and look at what the roof is shedding. A little granule loss in the first year after installation is normal, while steady accumulation at year nineteen is the roof telling you where it sits in its own life. What usually turns up on these wooded lots, job after job, is a mix: two or three curled tabs near the ridge, a patch of exposed fiberglass mat where the granules have gone, a nail head backing out, and a downspout that runs gritty after every hard rain. Cracked tabs and cupping edges belong on the same list.
The soft spot in the soffit is the finding that should move a homeowner from watching to calling. Soft wood means water has been sitting somewhere it should not, and water travels sideways along framing before it drips, so the stain is rarely underneath the actual hole. It might be failed step flashing, an ice dam from January, or shingles at the eave that gave up before the field did. Guessing which one from the driveway is how a small repair turns into deck replacement.
Sun Facing Slopes Age Years Ahead Of Others
Roofs do not age evenly, and on a lot with mature trees the gap between slopes gets dramatic. The south slope takes hours of direct afternoon sun, surface temperatures on dark shingles run well above air temperature, the asphalt loses its volatiles faster, and the mat underneath goes brittle years ahead of schedule. The north slope stays shaded, holds moisture longer, grows moss along the courses, and can look tired for reasons that have nothing to do with heat. Same house, same install date, same warranty, two different roofs.
Attic ventilation swings the whole thing further. Blocked soffit vents or an undersized ridge vent let heat pile up under the decking, and then the shingle cooks from both sides at once. On the house described here, the south slope had been living on borrowed time for two summers before anyone looked at the splash block. A useful inspection reports slope by slope with photographs, rather than grading the roof as a single number.
Ground Level Checks Answer Most Owner Questions
Most of what a homeowner needs to know can be seen without leaving the ground. Stand back at the property line with binoculars and read the ridge for sag, the field for dark streaks and missing tabs, and the valleys for packed debris. Check every splash block and the bottom of each downspout for grit. Then go inside, because the attic tells the truth faster than the exterior does.
With a flashlight, look for daylight at the eaves, dark staining on the underside of the decking, rusted nail shanks, matted or damp insulation, and any musty smell near the soffit line. Photograph what you find and write the date on it. If you want to know whether hail has genuinely hit your address, NOAA’s Storm Events Database is free to search by county and date, and it will tell you more than memory will about that storm you half remember from two summers back (most people are certain about the year and wrong about it). None of this requires a ladder.
What no homeowner should do is get up on the roof. Stay on the ground or in the attic and let a contractor with fall protection do the walking: after two workers tarping a storm-damaged two-story house slipped off without personal fall protection, one of them fatally, federal inspectors proposed $172,324 in penalties against their employer for allowing roof work above 20 feet without it. Trained crews wearing harnesses still fall. A nineteen year old shingle surface is loose underfoot by definition, and a ladder set on wet grass at the wrong angle needs no help from anyone.
Does A Thirty Year Warranty Mean Thirty Years Of Coverage?
Usually not, and the document tends to say so in the section nobody reads. Coverage is commonly prorated over time, tied to the material rather than the labor, and conditional on installation and ventilation requirements having been met. Terms differ by manufacturer, so check your own paperwork and ask an installer which parts still apply at year nineteen.
Can I Replace Just The South Slope?
Sometimes, and it is worth pricing out. A single slope replacement can make sense when the remaining slopes are genuinely sound and a color match is acceptable, though tie-ins at the ridge and the age of everything you keep complicate the math. Ask for both numbers, whole roof and one slope, and make the contractor explain what the cheaper option gives up.
How Fast Should I Move If I See Granules And A Soft Spot?
Granules on their own can wait for a scheduled inspection. A soft spot cannot, because active water is doing damage on a timeline of its own choosing. Get someone looking at it within a couple of weeks, and sooner if there is staining showing up inside the house.
Replace On Evidence Not On The Warranty Year
Decide on condition, and make the evidence do the arguing. Get two or three assessments from roofers Mequon WI homeowners have actually hired, insist on slope-by-slope photographs and a written scope, and compare what each one says about ventilation and flashing instead of reading only the bottom line. If the sun slope is bald and the soffit is soft, the warranty year is trivia. If the granules are holding and the attic is dry, you have time to plan and budget rather than react. Nineteen years and a printed promise of twelve more prove nothing on their own; the splash block does.
