Pre-Summer Roof Checkup: Metro Detroit Homeowner Checklist
Michigan winters are brutal on roofing systems. By the time April rolls around, your roof has endured months of freeze-thaw cycles, ice dams, heavy snow loads, and wind-driven sleet. Most homeowners in Sterling Heights, Troy, and across Southeast Michigan don't think about their roof until water starts dripping through the ceiling — usually during a summer thunderstorm when it's too late for a simple fix.
A pre-summer roof checkup isn't about paranoia. It's about catching small problems before they become expensive disasters. We've been providing Detroit roofing services since 1988, and the pattern is always the same: homeowners who skip spring inspections end up calling us in July with emergency leaks that could have been prevented with a $300 repair in April.
This checklist walks you through what to look for, what you can safely inspect yourself, and when to call a professional. Some of this you can do from the ground with binoculars. Some requires attic access. None of it requires climbing onto your roof — that's our job.
What Michigan Winters Do to Your Roof
Southeast Michigan sits in a climate zone that's uniquely hard on roofing materials. We get lake-effect snow from Lake Huron and Lake St. Clair, but we also get frequent thaws. That freeze-thaw cycle — where temperatures swing from 15°F at night to 38°F during the day — is what destroys roofs.
Here's the mechanical reality: water gets under shingles or into small cracks during a thaw. When temperatures drop overnight, that water freezes and expands. Ice takes up about 9% more volume than liquid water, which means it pushes shingles apart, widens gaps in flashing, and can even crack roof decking if enough water has infiltrated.
Over a typical Michigan winter, this cycle repeats 30 to 40 times. Each cycle causes microscopic damage. By spring, those microscopic problems have compounded into visible issues: lifted shingles, separated flashing, compromised sealant around pipe boots, and weakened valleys.
Ice Dam Aftermath: Even if you didn't see active ice dams this winter, the conditions that cause them — inadequate attic insulation and poor ventilation — still stress your roof. Ice dams force water under shingles in ways normal rain never does. The damage shows up weeks later as interior stains or rot in the roof decking.
The other winter factor is snow load. A cubic foot of fresh snow weighs about 7 pounds. Wet, compacted snow can weigh 20 pounds per cubic foot. A typical 2,000-square-foot roof with 18 inches of compacted snow is supporting roughly 30,000 pounds — 15 tons. Most roofs are engineered for this, but older roofs with compromised decking or framing can develop stress fractures or sagging.
This is why the roof replacement timeline in Novi and surrounding areas tends to spike in spring. Homeowners discover winter damage once the snow melts and the first warm rain hits. By then, roofers are booked solid for weeks.
Ground-Level Inspection: What You Can Check Safely
You don't need to climb on your roof to spot most problems. In fact, you shouldn't — roofs are slippery in spring, and walking on wet shingles can cause more damage than you're trying to diagnose. Here's what to check from the ground.
Granule Loss in Gutters
Walk around your house and look inside your gutters and downspouts. If you see significant accumulation of shingle granules — they look like coarse sand, usually dark gray or black — your shingles are deteriorating. Some granule loss is normal, especially in the first year after installation. But if you're seeing piles of granules or bare spots on shingles visible from the ground, the protective layer is wearing off.
Architectural shingles like CertainTeed Landmark or GAF Timberline HD are designed with a ceramic granule coating that protects the asphalt underneath from UV degradation. Once those granules are gone, the asphalt deteriorates rapidly. This is especially common on south-facing slopes that get the most sun exposure.
Shingle Condition from Ground Level
Use binoculars to inspect your roof from the street or yard. Look for:
- Curled or cupped shingles: Edges lifting up or curling under, usually a sign of age or poor attic ventilation
- Cracked shingles: Visible splits or breaks, often caused by thermal cycling or impact damage
- Missing shingles: Bare spots where wind has torn shingles off, common after winter storms
- Dark streaks or discoloration: Can indicate algae growth (cosmetic) or water infiltration (structural)
- Sagging sections: Dips or waves in the roofline suggest decking problems underneath
Pay special attention to areas where ice dams typically form — along eaves and in valleys. These are the spots most likely to show damage after a Michigan winter.
Flashing Around Chimneys and Vents
Flashing is the metal or rubberized material that seals the joints between your roof and vertical surfaces like chimneys, vent pipes, and skylights. It's also the most common failure point on residential roofs.
From the ground, look for:
- Rust or corrosion on metal flashing
- Gaps or separation where flashing meets brick or siding
- Cracked or missing caulk around flashing edges
- Lifted or bent flashing, especially after high winds
Chimney flashing is particularly vulnerable because it involves two different materials (metal and masonry) that expand and contract at different rates. The sealant that keeps water out degrades over time, and winter freeze-thaw cycles accelerate that process.
Gutter and Downspout Condition
Your seamless gutters in Detroit, MI are part of your roof system. If they're clogged, sagging, or pulling away from the fascia, water backs up and can infiltrate under shingles or rot the fascia boards.
Check for:
- Standing water or debris in gutters
- Gutters pulling away from the house (loose hangers)
- Rust spots or holes in metal gutters
- Downspouts that are disconnected or clogged
- Water stains on siding below gutter lines
If you're seeing gutter problems in Metro Detroit, spring is the time to address them before summer storms overwhelm a compromised system.
Soffit and Fascia Inspection
The soffit (underside of the roof overhang) and fascia (vertical board at the roof edge) are often overlooked until they're rotting. Walk around your house and look up at these areas. You're checking for:
- Peeling paint or water stains
- Soft or spongy wood (poke it gently with a screwdriver if you can reach)
- Gaps or holes where animals might enter
- Sagging or warped panels
Soffit and fascia damage usually indicates either gutter problems (water overflowing and soaking the wood) or roof edge issues (ice dams forcing water under the drip edge). Either way, it needs attention before it spreads. Our soffit and fascia guide covers why these components matter more than most homeowners realize.
Attic Inspection: Interior Warning Signs
The attic tells the truth about your roof's condition. This is where you'll see evidence of leaks, ventilation problems, and insulation failures that aren't visible from outside. You'll need a flashlight and the ability to safely navigate your attic space.
Water Stains on Roof Decking
Look at the underside of your roof decking (the plywood or OSB sheathing). Fresh water stains are dark and wet. Old stains are discolored but dry. Either way, they indicate water has gotten through your shingles at some point.
Note the location of any stains. Water travels, so the stain might be several feet away from the actual leak point. Look for patterns that follow roof valleys, flashing lines, or nail penetrations.
Daylight Through Roof Boards
On a bright day, turn off your attic lights and look for pinpricks of daylight coming through the roof. Any visible light means there's a hole — whether from a nail that backed out, a crack in the decking, or deteriorated sealant around a vent.
Small light leaks might not cause immediate problems, but they will during a wind-driven rain or when snow melts and refreezes.
Insulation Moisture
Touch your attic insulation (if it's fiberglass batts or blown-in cellulose). It should be completely dry and fluffy. If it's damp, compressed, or matted down, you have either a roof leak or a condensation problem.
Condensation happens when warm, moist air from your living space rises into a cold attic and hits the cold roof decking. The moisture condenses and drips back down onto the insulation. This is a ventilation and air-sealing issue, not necessarily a roof leak, but it needs to be addressed. Our Detroit insulation services often tie directly to roof performance.
Ventilation Check
Proper attic ventilation is critical in Michigan. You need intake vents (usually in the soffit) and exhaust vents (ridge vents, gable vents, or roof vents) to create airflow that keeps the attic temperature close to the outside temperature.
Check that soffit vents aren't blocked by insulation. Look for signs of adequate ventilation: the attic should feel cold in winter (not warm from heat escaping your living space) and should ventilate heat in summer.
Poor ventilation causes ice dams in winter and shortens shingle life in summer by trapping heat that "cooks" the shingles from underneath.
Mold or Mildew
Black or dark green spots on roof decking or rafters indicate mold growth, which requires moisture. This is a red flag for either active leaks or chronic condensation problems.
Mold isn't just a roof issue — it's a health and structural issue. If you see significant mold growth, you need both a roofing assessment and potentially a mold remediation specialist.
Critical Roof Components to Examine
Certain roof elements fail more often than others. These are the components that deserve extra attention during your spring checkup.
Pipe Boots and Penetrations
Every pipe that penetrates your roof (plumbing vents, exhaust vents) is sealed with a rubber boot or flashing. These boots are made of EPDM rubber or neoprene, and they deteriorate over time — especially in Michigan's temperature extremes.
A cracked pipe boot is one of the most common causes of roof leaks we see in Macomb County. The rubber dries out, cracks, and water runs straight down the pipe into your attic. Our guide on pipe boots and roof leaks explains why this $30 part causes so much damage.
From the attic, you can often see daylight around pipe penetrations if the boot has failed. From outside (with binoculars), look for cracked or separated rubber around vent pipes.
Valley Integrity
Roof valleys — where two roof planes meet — channel a lot of water. They're high-stress areas, and they're often the first place to show wear.
Valleys can be open (metal flashing visible) or closed (shingles woven or cut to form the valley). Either way, look for:
- Rust or corrosion in metal valleys
- Separated or lifted shingles along valley edges
- Granule loss concentrated in the valley trough
- Debris accumulation (leaves, twigs) that blocks water flow
Valley failures cause fast, dramatic leaks because they concentrate water flow. If you see valley damage, that's a priority repair.
Ridge Cap Condition
The ridge cap is the row of shingles that covers the peak of your roof. It's exposed to more wind than any other part of the roof, and it's often the first area to show wind damage.
From the ground, look for missing or lifted ridge cap shingles. Wind gets under these caps and can peel them off entirely. Once the ridge cap is compromised, water can enter along the entire peak of your roof.
Step Flashing
Step flashing is the interlocking metal pieces installed where a roof meets a vertical wall (like where a dormer meets the main roof, or where a roof meets a brick chimney). Each piece of step flashing should be layered with shingles so water can't get behind it.
Step flashing failures are harder to spot from the ground, but if you see water stains on interior walls near roof-wall intersections, step flashing is a likely culprit.
Drip Edge
Drip edge is the metal strip installed along the eaves and rakes of your roof. It directs water into the gutters and protects the fascia and roof decking from water infiltration.
Older homes in Royal Oak and Grosse Pointe Farms sometimes don't have drip edge at all — it wasn't required by code until the 1990s. If your home doesn't have drip edge, or if the existing drip edge is rusted or separated, water can wick back under the shingles and rot the decking.
When to Call a Professional Roofer
Some roof issues are DIY-checkable. Some require a licensed contractor with insurance and the right equipment. Here's when to pick up the phone.
Safety Concerns
If your roof is steep (more than a 6/12 pitch), slippery, or more than one story high, don't climb on it. Period. We see homeowners hurt themselves every spring trying to inspect roofs that should be left to professionals.
Even if your roof is accessible, wet shingles are slick, and spring mornings in Michigan often leave roofs damp with dew. It's not worth the risk.
Signs Requiring Immediate Attention
Call a roofer right away if you see:
- Active leaks or water stains spreading on ceilings
- Sagging roof sections or visible structural damage
- Large areas of missing shingles (more than a few)
- Significant granule loss across multiple roof slopes
- Daylight visible through the roof from the attic
- Extensive mold growth in the attic
These aren't "wait and see" problems. They're "call today" problems.

We're CertainTeed Master Shingle Applicators — the highest credential in residential roofing. We've completed over 500 projects across Southeast Michigan since 1988. When we inspect a roof, we're not looking to sell you a replacement. We're diagnosing what's actually wrong and what it'll take to fix it.
Cost Reality: Repairs vs. Replacement
Most spring roof issues can be repaired for $300 to $1,500, depending on the scope. A few missing shingles, a failed pipe boot, or damaged flashing are straightforward fixes.
But if your roof is 18+ years old, has widespread granule loss, or shows multiple failure points, repairs become a Band-Aid. At that point, you're looking at replacement — which for a typical 2,000-square-foot home in Metro Detroit runs $8,000 to $15,000, depending on shingle choice and complexity.
We'll tell you honestly which route makes sense. If your roof has 5-7 years of life left and needs a $600 repair, we'll do the repair. If your roof is on borrowed time and you're about to spend $2,000 patching it, we'll recommend replacement and explain why.
For a detailed breakdown, our post on 3-tab vs. architectural shingles in Michigan covers material costs and performance differences.
Preparing for Summer Storm Season
Once you've completed your spring checkup and addressed any issues, take these steps to prepare for summer weather.
Tree Trimming
Overhanging branches scrape shingles, drop debris into gutters, and become projectiles during storms. Trim any branches within 6 feet of your roof. This also reduces shade that promotes algae growth.
Gutter Cleaning Schedule
Clean gutters in late spring (after trees finish dropping seeds and flowers) and again in late fall (after leaves drop). Clogged gutters cause water to back up under shingles and overflow onto fascia boards. If you're dealing with recurring ice dams, gutter maintenance is part of the solution.
Documentation for Insurance
Take photos of your roof in good condition. If a summer storm causes damage, you'll have "before" documentation for your insurance claim. Include shots of all four sides of your roof, close-ups of shingles, and any unique features like skylights or chimneys.
Store these photos digitally with a date stamp. Insurance adjusters appreciate clear documentation, and it speeds up the claims process.
Emergency Contact List
Have a roofer's contact info saved before you need it. When a storm rips through Sterling Heights or Shelby Township and tears off shingles, every homeowner is calling for emergency repairs. The roofers who answer their phones are the ones with existing relationships.
We offer emergency tarp services for severe damage and prioritize existing customers. But even if you've never worked with us, call (844) 770-6398 and we'll do what we can to help.

Frequently Asked Questions
Inspect your roof twice a year — once in spring after winter damage and once in fall before winter sets in. Also inspect after any major storm with high winds or hail. Michigan's freeze-thaw cycles and severe weather make regular inspections more critical than in milder climates.
You can safely inspect from the ground using binoculars and check your attic for interior signs of damage. However, walking on your roof requires proper safety equipment and can cause damage if done incorrectly. For steep roofs, multi-story homes, or if you spot potential problems, call a licensed roofer. Professional inspections typically cost $150-$300 and include detailed documentation.
The most common issues we see are ice dam damage (lifted shingles along eaves), failed pipe boots (cracked rubber seals), separated flashing around chimneys, wind-damaged ridge caps, and granule loss from freeze-thaw cycles. Valley damage is also common because valleys concentrate water flow and ice formation.
Minor repairs like replacing a few shingles or fixing a pipe boot typically cost $300-$600. Flashing repairs around chimneys run $500-$1,200. More extensive repairs involving multiple areas or valley work can reach $1,500-$3,000. If your roof needs repairs exceeding $2,000 and is over 15 years old, replacement often makes more financial sense than continued patching.
Architectural shingles (like CertainTeed Landmark or GAF Timberline HD) typically last 20-25 years in Michigan when properly installed with adequate ventilation. Basic 3-tab shingles last 15-18 years. Our climate is harder on roofs than warmer regions because of freeze-thaw cycles and temperature extremes. Proper attic ventilation and insulation can extend roof life by preventing heat and moisture damage.
If your roof is over 15 years old or shows visible damage, replacing it before listing typically returns 60-70% of the cost in increased home value and faster sales. Buyers in Michigan are particularly wary of old roofs because they know the climate is hard on roofing systems. A new roof removes a major negotiating point and can prevent deals from falling through during inspection. Get a professional assessment to determine if replacement makes sense for your timeline and budget.
Insurance typically covers sudden damage from storms, wind, hail, or falling trees. It usually doesn't cover gradual wear, age-related deterioration, or damage from lack of maintenance. If a spring storm damages your roof, document everything with photos and call your insurance company immediately. We work with insurance adjusters regularly and can provide detailed damage assessments to support your claim. Keep in mind that if your roof is over 20 years old, some policies only pay depreciated value rather than full replacement cost.
