5 Signs Your Roof Needs a Professional Inspection

Signs Your Roof Needs a Professional Inspection

Shingles on the lawn after a Northwoods storm or a new attic stain can signal damage that a surface patch will not solve. The clearest signs your roof needs a professional inspection also include curling edges, granule loss, moss, and sagging.

For year-round homes, cabins, and lake properties around Rhinelander, Minocqua, and Eagle River, this guide explains what each symptom can mean, what you can check safely, and how Schmelling Contracting decides between a localized repair and full replacement.

Sign 1: Shingles in the Yard or Displaced After Storms

Finding shingles or broken shingle pieces on the lawn after strong wind is a direct warning that the roof covering has been compromised. Wind can break the adhesive seal between shingle courses. Repeated freezing and thawing can also loosen weakened materials. Once a shingle moves or disappears, the layers below have less protection from rain and melting snow.

From the ground, look for bare areas, raised tabs, uneven rows, torn ridge caps, or dark patches that were not visible before the storm. Binoculars or a zoomed-in phone photo can help. Do not climb onto a wet, icy, or storm-damaged roof.

We recommend an inspection when shingles appear on the ground. The visible loss may be localized, but nearby shingles can have creases or broken seals that are hard to see. Our assessment looks for the cause and extent of the damage rather than covering the exposed area with a temporary surface patch.

Sign 2: Curling, Cracking, and Granule Bald Spots

Aging shingles often show changes before they begin leaking. Edges may curl upward, corners can crack, and sections may cup so the center sits lower than the perimeter. These changes make it easier for wind-driven rain and snowmelt to work beneath the shingles.

Granules are the gritty mineral coating on asphalt shingles. Some loose material can occur after installation, but heavy deposits around downspouts or in gutters can point to deterioration. Bald patches that expose black asphalt or shiny matting have lost an important protective surface.

We look at how widespread the damage is. A few cracked shingles may be suitable for targeted roof repairs. Curling and bald spots across several slopes can indicate that the roofing system is failing more broadly. We also check for contributing conditions instead of assuming that replacing the visibly damaged shingles will solve the problem.

Sign 3: Moss Buildup Along Valleys and Keyways

Shaded roofs near trees may stay damp long after an open roof has dried. That moisture encourages moss along shingle edges, keyways, and valleys. Thick growth can hold water against the roof and conceal damage beneath it.

Moss is not only a cosmetic issue. Valleys carry a large share of the roof’s runoff, so heavy growth there can slow drainage and hide damaged materials. Avoid pulling up established moss or using aggressive pressure washing. Either approach can loosen shingles or remove more granules.

We inspect the surface beneath and around the growth, including the nearby flashing and drainage path. A limited affected area may need cleaning and repair, while widespread moss combined with brittle or curling shingles can support a replacement recommendation.

Sign 4: Sagging Roof Planes and Attic Water Spots

Changes in the roof’s shape need prompt professional attention. Stand well back from the home and look along the ridge and eaves. A bowed ridge, dipping area between rafters, or wavy roof plane may indicate weakened decking, framing movement, or prolonged moisture exposure.

The attic can reveal damage that is not yet visible in a finished room. Using a flashlight from a stable attic walkway, check for brown stains, wet insulation, rust around nail points, dark areas on wood, or daylight through the decking. InterNACHI identifies daylight, active drips, rusted fasteners, and moisture marks among the evidence found during an attic roof inspection.

Water spots on attic framing do not always sit directly below the entry point. Water can travel along decking, rafters, or fasteners before appearing. We trace that path and examine the roof above it so the repair addresses the opening rather than only the interior stain.

Snow makes structural concerns more serious in this region. According to the University of Wisconsin–Madison Extension, northern Wisconsin ground snow loads can range from 40 to 60 pounds per square foot or more. Stay clear of a visibly sagging area and arrange an assessment rather than walking on the roof.

Sign 5: Reaching the 20-Year Milestone with Recurring Leaks

Roof age becomes more meaningful when it appears alongside other symptoms. Reaching the 20-year mark is a sound reason to have the whole system evaluated, especially if shingles are brittle, seals are weakening, or past repairs are failing. Age alone does not prove that every roof needs replacement.

Repeated leaks are another warning. If water returns after prior patching or appears in different rooms, the problem may involve aging materials, flashing, decking, or several entry points. Patching each stain separately can leave the underlying failure untouched.

We assess the roof as a complete weather barrier. A small leak or a few damaged shingles may still call for repair. Widespread curling, sagging, missing shingles, storm damage, or recurring leaks on an older roof can make replacement the better long-term choice. Our repair-versus-replacement guide explains the factors in more detail.

What to Expect from a Professional Root-Cause Inspection

A useful inspection should explain why the damage happened and how far it extends. We begin with a detailed assessment of the visible roofing material and the areas where leaks commonly start. That includes roof edges, valleys, penetrations, flashing, drainage paths, and transitions around walls or chimneys where applicable.

We also look beyond the exterior surface. Accessible attic and structural areas can show damp insulation, stained framing, soft or deteriorated decking, and signs that water has followed a hidden route. This helps distinguish a contained defect from a roof-wide problem.

Schmelling Contracting provides free, detailed roof inspections with no upfront cost or pressure. After the inspection, we explain whether a localized repair or complete replacement is appropriate. You can also review our full shingle and metal roofing services before deciding how to proceed.

When storm damage is present, we evaluate whether an insurance claim may be warranted. We can help document the affected areas and guide you through the claim paperwork. If it is safe, take ground-level photos of exterior damage and pictures of interior water stains before cleanup. Do not put yourself at risk to obtain close-up roof photos.
