Roofs in Southeast Michigan Homes: What Inspectors Check Before Leaks and Shingle Damage Catch Up With You

Southeast Michigan roofs work hard. Between heavy snow loads in Oakland County, summer hailstorms rolling through Macomb, and the freeze-thaw cycles that hit Wayne County every spring and fall, roofing materials take a beating year-round. A roof that looks fine from the driveway can still be hiding damage that leads to leaks, mold, or costly interior repairs. During a home inspection, the roof is one of the first systems we evaluate because problems here tend to cascade into other parts of the house.

Here's what we're actually looking for, and why it matters to buyers, sellers, and owners alike.

Shingle Condition and Age

Asphalt shingles are the most common roofing material in our region, and their condition tells a story. We check for:

• Curling, cupping, or cracked shingles, often a sign of age or heat damage
• Granule loss, which shows up as bald spots or excessive grit in gutters
• Missing or lifted shingles from wind events, which are common in open subdivisions and lakefront areas
• Patchwork repairs that may indicate a history of leaks

Most asphalt shingle roofs in this area last somewhere between 15 and 25 years depending on material quality, ventilation, and installation. If a roof is nearing the end of that range, it's worth budgeting for replacement even if no active leaks are present yet.

Flashing, Valleys, and Penetrations

Leaks rarely start in the open field of a roof. They start at the details: chimney flashing, skylight seals, plumbing vent boots, and roof valleys where water concentrates. We pay close attention to these areas because flashing failures are a leading cause of hidden water intrusion, especially on older Detroit-area homes where roofs have been re-covered multiple times without properly updating flashing details.

Ice Dams and Winter Damage

Michigan winters create a specific risk: ice dams. When heat escapes from the attic, it melts snow on the upper roof, which then refreezes at the colder eaves. This backs up water under the shingles and can force it into the attic or exterior walls. We look for signs of past ice damming, including stained sheathing, damaged gutters, or compressed insulation near the eaves, since this often points to attic ventilation issues as much as roofing issues.

Gutters, Drainage, and Roof-to-Wall Transitions

A roof doesn't work in isolation. Clogged or undersized gutters, poor downspout extensions, and roof-to-wall transitions that funnel water toward the foundation all show up in our evaluation. These issues are often easy to fix but get overlooked until water finds its way into a basement or crawl space.

What We Use to Inspect Roofs

Depending on roof pitch, accessibility, and weather conditions, we use a combination of direct roof walks, ladder inspections, and drone surveys to get a complete picture, including angles that are difficult or unsafe to access on foot. Thermal imaging can also help identify areas of moisture intrusion that aren't visible to the naked eye.

Why This Matters for Buyers and Sellers

For buyers, a roof in poor condition is a major negotiating point and a near-term expense to plan for. For sellers, addressing visible roof issues before listing can prevent surprises during a buyer's inspection and keep a deal on track. For long-term owners, catching small issues early, a lifted shingle, a failing seal, a clogged gutter, is almost always cheaper than dealing with the water damage that follows if they're ignored.

A roof is one of the most expensive systems to replace and one of the most important to get right. A thorough inspection gives you the information you need to plan ahead, whether that means budgeting for a few more years of life or negotiating a replacement before closing.
