A Ground-Level Walkaround That Shows You Where Your Home Is Most Likely to Fail

Most homeowners only look closely at their home's exterior after a storm has already done its work. By then, the walkaround is a damage report. What follows here is the opposite: a proactive, ground-level audit you do before the weather turns, so you know where your home is exposed while there is still time to act.
Think of it as a pre-flight check for your house. You are not diagnosing every defect or climbing onto anything. You are walking a slow lap around your property with your phone in hand, looking at eight exterior systems that carry the most storm risk, and sorting what you see into three buckets: fine for now, worth securing today, or worth a professional's eyes. Twenty minutes, one loop, no specialized tools.
This guide is built around that loop. Each chapter takes one exterior zone — the roof as seen from the ground, siding, soffits and fascia, the garage door, trees and limbs, loose outdoor items, drainage, and pre-storm documentation — and gives you three things: what to look for, why it matters in hail and wind, and what to do next. The chapters are deliberately short and scannable, because a good audit is something you can actually repeat each season, not a one-time project.
A quick note on what this is not. This is not an insurance guide, a repair tutorial, or a reason to get on a ladder. Every check here is done with both feet on the ground. Where something looks serious, the right move is almost always to document it and call a qualified professional — not to fix it yourself in the hour before a storm. With that framing set, let's start with what you are actually checking for.
Before you walk the loop, it helps to know what "severe" really means in Canadian terms — because the threshold is lower than most people assume. Environment and Climate Change Canada issues a severe thunderstorm warning when wind gusts reach 90 km/h or more, or when hail reaches 2 cm in diameter or larger, according to Environment and Climate Change Canada. Two centimetres is roughly the size of a toonie. That is not a rare, once-a-decade event; in much of the country it is a normal summer afternoon.
Those two forces — wind and hail — attack a home in different ways, and knowing the mechanism is what turns a vague "look for damage" into a useful check. Hail bruises and pits surfaces. It strips protective granules off shingles, cracks aging siding, and dents soft metal. Public Safety Canada notes that hail can fall at considerable speed, especially when driven by high winds, causing real damage to buildings and property. Wind works differently: it finds edges and openings, gets underneath things, and peels. Environment and Climate Change Canada's Enhanced Fujita Scale damage indicators show that rising wind speeds first strip roof-covering materials and siding, and at higher intensities lift roof decking and collapse garage doors. The pattern is consistent: storms exploit weak edges, loose fasteners, and large unbraced surfaces first.
That is why this walkaround is organized around zones rather than a single "check the roof" instruction. In Canada's hail-prone regions, damage rarely lands in one place. Severe hailstorms around Calgary's so-called "hail alley" have driven billions of dollars in insured losses, with repairs routinely spanning roofing, siding, eavestroughs, fascia, and sometimes garage doors and windows together. Your home is a system. The check treats it like one.
This is a resilience habit, not a one-time task. The City of Calgary expects damaging hail and high-wind gusts to keep recurring as the climate shifts, which is why a short seasonal walkaround — ideally before summer storm season and again after any major event — is worth more than a single deep inspection you never repeat.
The whole point of a time-boxed check is that you will actually do it. Twenty minutes is enough to walk the perimeter of most homes twice — once looking up, once looking down — if you know the route before you start.
Timing. The best window is a calm, dry day with good light, before any storm is in the forecast. Mid-morning or late afternoon sun rakes across surfaces at an angle and makes dents, ripples, and lifted edges far easier to see than flat noon light. Aim to do this at the start of storm season, and again if a severe-weather watch appears for your area. For homeowners who want the fast version of pre-storm prep when a watch is already posted, our companion piece on quick homeowner steps before the next round of storms covers the last-minute moves.
Tools. Nothing specialized. Your phone (camera plus a notes app), a flashlight for shaded areas like soffits and under eaves, and optionally a pair of binoculars so you can study the roof and roofline closely without leaving the ground. That is the entire kit. CMHC's homeowner maintenance publications make the case that non-experts can catch a surprising number of issues with nothing more than a simple visual checklist and a walk around the building, as outlined in CMHC's maintenance guidance. The checklist below is yours.
Safety boundaries. This is the rule that matters most: everything here is a ground-level check. Do not climb onto the roof, do not lean a ladder against the house to "get a better look," and do not go out during a wind or hail warning to secure anything if it puts you in the storm's path. If a zone can only be assessed properly from height or up close on the roof, that is precisely the signal to bring in a professional. The walkaround's job is to tell you where to look harder, not to send you up there.
Never perform this check during an active storm or high-wind warning. Falling hail and wind-borne debris cause serious injuries, and no exterior item is worth securing while it is happening. Do the audit ahead of time so that when a warning is issued, your only outdoor task — if any — is quick and already planned.
Here is the master route. Walk it in this order, and use it as the checklist you screenshot or print and carry with you.
You can learn most of what you need about a roof without ever touching it. From a few vantage points around the house — and with binoculars if you have them — scan the shingle field for the three signals that matter: shingles that are missing, shingles that are curling or lifting at the edges, and patches that look darker or "balder" than the rest. The City of Calgary's Climate Ready Home guidance recommends exactly this kind of ground-level look, checking for missing, damaged, or curling shingles and confirming that roof edges and flashing appear secure, since those are the areas most prone to wind uplift and hail impact, as detailed in Calgary's Climate Ready Home guide.
Hail damage is subtler than wind damage and easier to miss. Instead of an obviously missing shingle, hail leaves bruising, granule loss, and small dark spots where the protective surface has been knocked off and the mat underneath is exposed. Those bruises may not leak this year. But repeated hail impacts shorten a roof's life even when no water is getting in yet, so a roof that looks "mostly fine" after a hailstorm can still be quietly aging faster than it should. That is worth photographing and monitoring, not ignoring.
There is also a longer-game point here, and it belongs in the body rather than a footnote: not all roofs resist hail equally. Impact-resistant products — Class 4-rated roofing, and more resilient claddings like fibre-cement — hold up better against hail than standard materials. You will not re-roof your house before a storm this weekend, but if replacement is already on your horizon, that is the moment to ask a roofer about impact-rated options. The walkaround's job is to flag whether your current roof is showing wear; the material conversation is what you carry into your next roofing decision. If your ground check turns up several of the warning signs above, our guide to common roof-replacement warning signs homeowners overlook helps you tell normal aging from a roof that is near the end.
Photograph the roof from the same two or three spots every season — a front corner, a back corner, and straight on. Consistent angles make it obvious when a shingle goes missing or a patch darkens between checks. Your phone's timestamp does the record-keeping for you.
Siding is a large, flat, wind-catching surface, which is exactly why wind likes it. Walk the full perimeter and look — and gently listen — for panels that are cracked, warped, loose, rattling, or missing. The failure mechanism is simple: once a panel's edge is loose, wind gets behind it, pries it further, and can tear it off, which then exposes the wall underneath and gives the next gust a bigger edge to grab. The City of Calgary advises homeowners to inspect walls and siding for cracked, warped, loose, or missing panels and to secure them, precisely because these defects let wind get behind the cladding and pull it off in storms, according to the City of Calgary's home maintenance guidance.
Pay attention to sound as much as sight. On a breezy day, a panel that ticks, buzzes, or rattles is telling you its fasteners have let go even if it still looks flush. Run your eyes along the bottom edges and corners, where cladding most often starts to lift. Cracks around a warped panel are a hail-and-age signal; a section that moves when a light gust hits it is a wind signal. Both go on your list, but the loose, movable panel is the more urgent of the two — it is the one most likely to leave during the next storm.
While you are at the walls, glance at the windows and the seals around doors. Cracked caulking or visible gaps around frames are small to fix and easy to overlook, but wind-driven rain finds them fast. The City of Calgary recommends checking and maintaining the caulking and seals around windows and doors and repairing any gaps to keep water out during heavy, wind-driven rain. This is low-effort maintenance with a high storm-season payoff.
If the roof surface is the part everyone thinks about, the roof edge is the part that actually fails first — and it is largely invisible unless you look for it. Soffits (the panels tucked under the eaves) and fascia (the boards that cap the roof edge) form the seam where wind pressure concentrates. The Institute for Catastrophic Loss Reduction notes that in severe wind events, the most common residential damage occurs at roofs, exterior walls, and openings, with unprotected edges and weak connections acting as the typical failure points, as documented in ICLR's wind research. An open or loose edge is an invitation: once wind gets under the roofline, it can start lifting the covering from the perimeter inward.
From the ground, look up under the eaves with your flashlight. You are watching for soffit panels that sag, gap, or have already popped loose, and for fascia that looks stained, warped, or detached. Staining is a useful early tell — discolouration at the soffit or fascia often shows up long before any interior ceiling stain, because water gets into the roof edge first. A panel already hanging or blown open is a high-concern finding: it means the edge is compromised now, before the storm, and wind will make it worse quickly.
Because edge problems and roof-surface problems share a cause and often travel together, treat anything you find here as connected to the roof section above rather than a separate issue. If you are seeing edge staining alongside shingle wear, the roof edge deserves a professional look; our guide on early detection and emergency fixes for roof leaks walks through what those early signs usually mean and when they warrant action.
Here is the counterintuitive part of the whole walkaround: on many homes, the single most consequential exterior component in a windstorm is not the roof. It is the garage door. It is the largest continuous surface on the house, and it is often the least reinforced.
The mechanism is worth understanding because it reframes how seriously to take this zone. A large, unreinforced garage door that fails inward does not just cost you a door. The Institute for Catastrophic Loss Reduction points out that when a garage door blows in, wind pressure builds up inside the structure and can push outward on the roof and walls from within, contributing to roof and structural failure, as explained in ICLR's high-wind guidance. In other words, a two-hundred-dollar door failing can cascade into a roof problem. That is why the federal Enhanced Fujita Scale damage indicators list garage-door collapse as a marker of serious wind damage, right alongside roof-decking uplift.
From the ground, this is an easy check. Look at the door face for dents, bowing, or panels that are pushed out of plane. Check the tracks on each side for looseness or misalignment. Look for any visible bracing or reinforcement struts across the back of the door (you can usually see these from inside the garage). A door that visibly bows, rattles hard in ordinary wind, or has no bracing at all is a strong candidate for a professional assessment — and, when the time comes, for a wind-rated replacement.
Do not treat the garage door as a minor item just because it is easy to overlook. Of everything on this walkaround, a weak garage door has the most outsized potential to turn a survivable storm into a structural one. If yours shows bowing, damage, or has no bracing, put it at the top of your "call a pro" list.
Some of the worst storm damage to a home never touches the home directly until a tree delivers it. Falling trees and broken branches are among the leading hazards in windstorms, and Canadian preparedness guidance is consistent on the point: monitor and manage trees that show decay, broken limbs, or branches overhanging the roof and power lines, as Public Safety Canada advises in its severe storm preparedness materials.
Walk the yard and look up at your trees the way wind will test them. You are watching for dead or clearly cracked limbs, branches that rest on or hang directly over the roof, limbs near or touching power lines, and any trunk that leans noticeably or has visibly lifted soil at its base. A single dead limb suspended over the roof or the driveway is a high-concern finding — not because it will definitely fall, but because if it does, it lands on the most expensive part of your property.
The action here is one of the clearest lines in the whole guide: this is where you hire out. Corrective pruning of large limbs, and removal of hazardous trees, is qualified-arborist work, not homeowner ladder work — and anything near a power line is strictly a utility or professional matter. Your job on the walkaround is to spot the hazard and note it; the saw belongs to someone trained and equipped. Property-wide vegetation management around the house is also a theme in seasonal prep more broadly, and our Canadian wildfire-season property checklist covers the overlap between storm-limb clearance and defensible landscaping.
This is the fastest, most controllable win on the entire list — and the one most people skip until the sky darkens. In high wind, ordinary yard items become projectiles. Patio furniture, barbecues, planters, bins, garden décor, umbrellas, and especially light, large-surface items like trampolines can all be picked up and thrown into siding, windows, and vehicles. Calgary's hail and high-wind guidance, in line with federal severe-storm advice, is direct about securing or storing loose outdoor items before a storm for exactly this reason.
The check is quick: as you walk the property, mentally sort everything not attached to the ground into three groups — things you can move into the garage or shed, things you can tie or weigh down in place, and things too large to secure fast. That third group is the one to plan for now, before a watch is ever issued, because you do not want to be problem-solving a loose trampoline in a rising wind.
Build a two-minute "storm list" today: the specific items you would move or tie down if a warning came, and where each one goes. Tape it inside the garage. When a watch is posted, you execute a known plan in a couple of minutes instead of improvising in the weather.
Wind and hail get the headlines, but a lot of storm damage is simply water that had nowhere good to go. A storm-ready exterior sheds water away from the building, and this zone is where you confirm it does. Look at three things: your downspouts, your gutters (eavestroughs), and the ground itself.
Start at the base of each downspout. It should carry water well away from the foundation, not dump it against the wall — a disconnected or too-short downspout puddling at the foundation is a common and fixable problem. Then look up at the gutters from the ground for sagging runs, overflow stains, or vegetation growing out of them; blocked or sagging eavestroughs overflow in heavy rain and can drive water down the siding and against the foundation. Finally, check the grade: the soil should slope away from the house, not toward it. The City of Calgary's maintenance guidance ties all three together, advising homeowners to keep grading sloped away from the foundation, ensure downspouts discharge well clear of the building, and keep eavestroughs and downspouts clear of debris so they perform in heavy rainfall.
None of this requires tools or height. Standing water against the house after ordinary rain, or a downspout emptying right at the foundation, are the two findings to act on soonest. For a deeper seasonal routine on keeping water where it belongs, our spring flood-prep checklist extends this drainage logic into a full pre-season list.
Good drainage is the quiet hero of storm resilience. Even when wind and hail leave the roof and walls intact, poor water shedding can still cause real damage during the same storm. It is the zone most likely to be overlooked precisely because it never looks dramatic.
The last step of the walkaround is the one that pays off only if something goes wrong — which is exactly why it is worth the two minutes. Before any storm, capture the current condition of your home's exterior. The Institute for Catastrophic Loss Reduction emphasizes that documenting the state of roofs, siding, windows, and other exterior features before severe weather makes it far easier to understand what actually changed afterward, as noted in ICLR's homeowner resources. A dated "before" set turns a vague post-storm impression into a clear comparison.
Keep it simple and systematic. As you finish the loop, take dated photos or a slow video of each zone — a full pass of each elevation of the house, plus close-ups (zoomed from the ground) of anything you flagged. You are not building a legal file; you are building a baseline you can compare against later. The timestamp your phone adds is doing the heavy lifting.
Then protect the record. Storing those photos only on the device in your pocket defeats the purpose if the device is lost or damaged. Public Safety Canada's preparedness guidance recommends keeping important records in safe, accessible places and using digital backups to protect them during disasters — the same principle applies perfectly to your exterior photos. Back them up to cloud storage or a second location so the baseline survives whatever the storm does.
You have walked the loop and taken your notes. Now translate them into action. The point of the audit was never a repair list — it was a triage. Sort every finding into one of three levels, and let the level dictate the response.
The dividing line between medium and high is simple: medium is "loose," high is "failing or dangerous." A rattling panel is medium; a panel already gone is high. Cracked caulking is medium; a hanging soffit is high. When you are genuinely unsure which side of the line a finding sits on, treat it as the higher one and get a professional opinion — the cost of an inspection is small next to the cost of a preventable failure.
There is a genuinely encouraging finding underneath all of this, and it is worth ending on. Relatively modest, low-cost resilience measures tend to deliver outsized protection: research on high-wind safety for Canadian homes has found strong benefit-to-cost ratios for straightforward wind-resilience improvements, with many homes staying vulnerable simply because those measures are not yet standard practice, as summarized in ICLR's research on high-wind safety. You do not need to armour the entire house. Fixing the clearly failing things — the loose edge, the weak garage door, the dead limb — moves the needle more than most people expect.
For a broader view of where these staged upgrades are heading, the ICLR and CHBA tiered resilience guidelines lay out how homeowners can build protection in stages.
Do the loop before storm season. Fix what is easy. Document the rest. Call a pro for anything at height or clearly failing. Twenty minutes, once a season, is a small price for knowing your home can take the next hit.

At minimum, once at the start of storm season, and again after any severe hail or wind event. If a severe-weather watch is posted for your area, a quick pre-storm pass to secure loose items is also worthwhile. Because damaging storms are expected to keep recurring in much of Canada, treating this as a seasonal habit rather than a one-time task gives you the most protection.
Environment and Climate Change Canada issues a severe thunderstorm warning when wind gusts reach 90 km/h or more, or when hail reaches 2 cm in diameter or larger — roughly the size of a toonie. Both thresholds are common summer occurrences in many regions, which is why proactive checks matter even for "ordinary" storms.
No. Every check in this guide is done from the ground. If a zone can only be assessed properly from the roof or up close at height, that is your signal to call a professional. Climbing onto the roof or leaning a ladder against the house introduces more risk than the check is worth.
A garage door is usually the largest, least-reinforced surface on a house. If a large, unreinforced door fails inward during high wind, pressure builds inside the structure and pushes outward on the roof and walls, which can turn a door failure into roof or structural damage. Its size and vulnerability give it outsized importance.
Hail damage tends to show as bruising, dark spots, and granule loss — patches where the shingle's protective surface has been knocked off. Normal wear is more uniform and gradual. A useful tell is change over time: photographing the roof from the same angles each season makes new bruising or bald patches obvious. When in doubt, document it and have it professionally assessed.
Very little — your phone for photos and notes, a flashlight for shaded soffits and eaves, and optionally binoculars to study the roof and roofline from the ground. No specialized equipment is required.
Not necessarily. Hail can bruise shingles and cause granule loss without producing an immediate leak, and repeated impacts shorten a roof's life even when no water is getting in yet. If you saw significant hail, it is worth photographing the roof from the ground and considering a professional inspection, even if nothing looks dramatic.
Flag it as high concern and hire a qualified arborist. Corrective pruning of large limbs and removal of hazardous trees is professional work, and anything near a power line must be handled by the utility or a qualified professional. Do not attempt limb removal from a ladder yourself.
Walk the full perimeter at ground level and look for panels that are cracked, warped, loose, or missing. On a breezy day, listen too — a panel that rattles or buzzes has likely lost its fasteners even if it still looks flush. Pay special attention to bottom edges and corners, where cladding tends to start lifting.
In severe wind and hail events, damage most often concentrates at roofs, exterior walls and siding, roof edges (soffits and fascia), openings like doors and windows, and garage doors. In hail-prone regions, repairs frequently span several of these at once rather than a single component.
If wind is in the forecast, yes. Ordinary yard items — furniture, planters, bins, umbrellas, and especially trampolines — become projectiles in high wind and can damage siding, windows, and vehicles. Moving or tying them down is one of the fastest, most effective actions you can take.
Severe storms bring heavy, often wind-driven rain. If downspouts dump at the foundation, gutters are blocked or sagging, or the ground slopes toward the house, water can damage siding and foundations even when the roof and walls hold. Good water shedding is a core part of storm resilience.
Do a full pass of each side of the house, plus ground-level close-ups of anything you flagged during the walkaround. Dated photos or a slow video create a "before" baseline that makes it far easier to see what changed after a storm. Your phone's timestamp handles the dating automatically.
Not only on the phone in your pocket. Back them up to cloud storage or a second location, in keeping with general preparedness guidance to keep important records safe and accessible with digital backups. That way the baseline survives even if a device is lost or damaged.
Any time a finding is "failing or dangerous" rather than merely "loose" — missing shingles, lifted flashing, a hanging soffit, a bowing garage door, a dead limb over the roof, or standing water against the house. Anything requiring roof access or height is also a professional job. When you are unsure which category a finding falls into, treat it as the more serious one.
Yes. Impact-resistant products such as Class 4-rated roofing and more resilient claddings like fibre-cement withstand hail better than standard materials. You would not replace them before a single storm, but if a roof or siding replacement is already on your horizon, it is worth asking about impact-rated options at that time.
