Minnesota sits inside one of the more active severe-weather corridors in the Upper Midwest. The western and northern Twin Cities suburbs — including Plymouth, Maple Grove, Minnetonka, and Wayzata — sit squarely in the path of the supercell thunderstorms that regularly move through the metro from spring through late summer. Large hail, straight-line wind, and derecho-style wind events aren't rare occurrences here; they're a predictable part of the Minnesota storm season, and siding is almost always the first exterior surface to show it.
The state's severe weather season typically runs from late April through September, with the highest concentration of damaging hail and wind events landing in May, June, and July. Twin Cities homeowners have lived through some genuinely historic events during this window, including widespread derecho wind damage across the metro in 2022 and repeated large-hail outbreaks that triggered thousands of insurance claims in a single storm cycle. When a storm like that rolls through, roofing and siding damage tend to travel together — if your shingles took a hit, your siding almost certainly did too.
Because so many homes in a single neighborhood get hit at once, contractor demand spikes fast after a major storm. Getting your siding inspected and documented early — before the rush — puts you in a much stronger position with your insurance carrier and your restoration timeline.

Storm damage isn't always obvious from the driveway. Hail and straight-line wind leave marks that homeowners miss for months — until a small crack becomes a moisture problem behind the wall. Here's what our inspectors look for on every storm damage siding replacement in Plymouth and the surrounding suburbs.
Small, round dents or divots, often clustered on the side of the house facing the storm
Cracked or chipped vinyl panels, especially near the bottom edge or nail hem
Spider cracking radiating out from a single impact point
Granule loss or chalky residue on fiber cement and engineered wood siding
Dents in aluminum trim, fascia, soffit, and downspouts that match siding damage
Panels that have popped loose, buckled, or visibly warped away from the wall
Missing sections after a gust event, particularly on gable ends and upper stories
Lifted corners and J-channel separating from window and door trim
Rattling or loose panels that move when pressed by hand
Debris impact marks from tree limbs, shingles, or fencing carried by straight-line wind
Compromised weather barrier behind cracked panels, allowing moisture intrusion
Soft or discolored sheathing where water has tracked behind damaged siding
Fastener stress from repeated flexing during high-wind events
UV and impact-weakened panels that fail during the next storm, not this one
Damage is visible from the street, or a neighbor has filed a claim
Your roof was also hit — siding and roofing damage almost always travel together
It's been more than a year since your last exterior inspection
You're preparing to sell and need documentation of your home's condition
National Weather Service hail reports are measured against common objects. Here's roughly how each size translates to real damage risk on vinyl and fiber cement siding, based on what our crews see across Twin Cities storm claims.
< 0.5 IN - Pea
Low risk. Rarely marks siding; may bruise landscaping.
0.75 IN - Penny
Low-moderate. Cosmetic dents possible on soft aluminum trim.
1.0–1.25 IN - Quarter / Golf Ball
Moderate-high. Common threshold for vinyl cracking and dented gutters.
1.75 IN - Golf Ball
High. Frequent siding fractures, torn screens, dented roof vents.
2.5 IN + Tennis Ball / Baseball
Severe. Structural roof and siding damage, broken windows likely.
We assess every exterior surface in the scope, not just the siding panels. Soffit, fascia, window surrounds, corner posts, and any aluminum trim components are inspected for impact damage alongside the field panels. On homes where the roof is also being replaced, the siding and roof assessment happen in the same visit so the complete exterior scope is documented together before any insurance estimate is written.
Our siding assessments are organized by component category with photographs attached to each line item. When the adjuster's scope comes back, we review it against our documentation and identify any components that were missed or undervalued. This is the step that produces the supplement when the initial scope does not reflect the full extent of what the storm actually did to the exterior.
Proof Builders installs vinyl, EDCO Steel, LP SmartSide engineered wood, and fiber cement including James Hardie profiles, and can advise on which material best fits the home's exposure, the community's color requirements, and the homeowner's maintenance preferences. All three material types carry manufacturer warranties and all are appropriate for Plymouth's climate when installed correctly.
Siding removal reveals the condition of the housewrap or felt paper beneath. Where the existing moisture barrier is torn, compressed, or deteriorated, it is replaced before new siding goes on. The single most common failure point in siding installations is the weather barrier and flashing detail at windows and door openings. Every window opening is flashed before siding is cut and locked into place around it. This step is where shortcuts produce the moisture intrusion problems that appear two to four years after installation.
After installation we walk the full perimeter and document the completed system. All manufacturer warranty paperwork is provided to the homeowner at close of job along with installation photographs. For projects covered by insurance, we coordinate final documentation with the claim timeline so the homeowner has a complete record for both the warranty and the claim file.
Look for small round dents or cracks concentrated on the side of the house that faced the storm, chalky residue or granule loss on fiber cement panels, and dented gutters, downspouts, or window screens nearby — damage in those areas is a strong sign your siding was hit too. A free inspection is the most reliable way to confirm it, since a lot of hail damage isn't visible from the ground.
Most Minnesota homeowners policies cover siding damage caused by a specific storm event, such as hail or straight-line wind, subject to your deductible. Coverage details vary by carrier and policy, including how "matching" undamaged sections is handled. A documented inspection and prompt claim filing give you the best chance at full approval.
Filing windows vary by policy, but many Minnesota homeowner policies allow one to two years to file a claim tied to a specific storm date. Waiting too long can also make it harder to prove the damage was storm-related rather than gradual wear, so we recommend scheduling an inspection as soon as you suspect damage.
This is common, especially after large regional storms when adjusters are managing high claim volumes. We can meet the adjuster on-site, walk through our documentation, and request a supplement to the estimate. Most carriers have a formal reinspection or appraisal process for exactly this situation.
It depends on the extent of damage, whether the original siding profile and color are still available, and what your policy's matching provisions allow. We'll always present the most cost-effective option that meets code and your insurer's requirements, along with a full-replacement option if a true match isn't achievable.
