Spring Roof Inspection Checklist for St. Louis

A 12-point spring roof inspection checklist for St. Louis homeowners — what to look for from the ground, what pros check that you can't see, and what to do next.

Spring is the best time to inspect your roof in St. Louis — and the most important. By April, your roof has survived the full weight of winter: ice accumulation, freeze-thaw cycles, heavy snow loads, and winter wind events. And by late May, the first wave of spring hail and severe weather season is already running. A spring inspection catches winter damage before it compounds and sets you up with documentation before storm season peaks.

Why Spring Timing Matters in St. Louis

Missouri's freeze-thaw cycle is one of the most damaging weathering forces on a roof. Water infiltrates small cracks in shingles or flashing, freezes, expands, and widens the crack — then thaws and refreezes repeatedly across a typical St. Louis winter. By spring, damage that began as a hairline crack may have opened significantly. Catching these issues in March or April means a repair appointment in May or June — before summer heat and storm season arrive.

Spring also gives you an important strategic advantage for insurance purposes. A documented pre-storm-season inspection establishes a baseline condition for your roof. If a hail storm hits in June and you file a claim, that spring inspection report distinguishes storm damage from pre-existing wear — which matters when adjusters assess scope.

The 12-Point Ground-Level Self-Inspection

You do not need to climb on your roof to do a useful inspection. In fact, we recommend against homeowner roof climbing — the risk of a fall isn't worth what you can see. A pair of binoculars and a walk around the full perimeter gives you most of the information you need to know whether a professional inspection is warranted.

1. Shingle Condition on All Slopes

Look for visible curling, cupping, or missing shingles on every slope. Pay attention to the south-facing slope, which takes the most direct sun exposure. Dark streaking (algae) is cosmetic; curling is structural.

2. Ridgeline

The ridge cap shingles at the peak of the roof are among the first to show wind damage. Look for any that appear raised, cracked, or have blown off. A wavy ridgeline can also indicate decking movement.

3. Valleys

Valleys carry concentrated water flow. Look for worn or missing shingles along the V-channel, exposed flashing, or visible gaps in valley seams.

4. Gutters and Downspouts

Check for granules accumulated in gutters or at downspout discharge points — a primary aging indicator. Also look for gutters that have pulled away from the fascia, which affects water drainage off the roof edge.

5. Soffit and Fascia

Peeling paint or soft spots on fascia boards indicate water infiltration at the roof edge — often from ice dam damage or gutter failure. Discolored or stained soffit can signal attic moisture problems.

6. Chimney and Flashing

Look for rust-staining on mortar at the chimney base, gaps between flashing and masonry, or visible caulk that's cracking. Chimney flashing is a leading source of roof leaks in St. Louis's older housing stock.

7. Pipe Boots and Penetrations

Rubber pipe boots around plumbing vents crack and deteriorate — typically after 10–15 years. With binoculars, look for cracked or collapsed rubber around any vent pipe. This is a common but easily repaired leak source.

8. Roofline Straightness

Step back and look at the roofline from multiple angles. It should be visibly straight. Any dips, waves, or sags indicate deck issues that require closer inspection.

9. Attic: Staining and Moisture

Spend five minutes in the attic with a flashlight, looking for water stains on rafters or decking, daylight visible through the deck, or soft/spongy spots when pressing on the sheathing. Mold or mildew indicates a chronic moisture problem.

10. Attic: Ventilation Check

Feel for air movement at soffit vent channels and ridge vent. Blocked intake vents (common when insulation has been blown over them) drive up attic temperatures and accelerate shingle aging. Inadequate ventilation is a leading cause of premature roof failure in St. Louis.

11. Ceiling Stains Inside the Home

Check ceilings near exterior walls, around chimneys and skylights, and in top-floor rooms for any yellow-brown water staining. Active leaks show up as damp spots; older leaks leave distinct stain rings.

12. Photo Documentation

Take date-stamped photos of anything that looks unusual. These photos are valuable context for a professional inspector and serve as a pre-storm baseline for insurance purposes.

What a Professional Inspection Adds

A certified roofing contractor on the roof sees things that ground-level inspection cannot: granule adhesion tested by hand, soft-spot mapping across the full deck, up-close flashing condition at every transition, ventilation intake and exhaust measurements, and hail impact patterns that require trained identification. After a significant winter, a professional spring inspection is worth scheduling even if your ground-level check found nothing obvious.

When to Schedule a Pro Inspection

Schedule a professional inspection if: your roof is 12 or more years old, you found any of the ground-level warning signs above, you experienced a significant winter ice event or wind event, or you're planning to sell the home within the next two years. For storm-event inspections, schedule as soon as it's safe after the event — insurance claim timelines are real, and the inspection report is your first piece of documentation.

What to Do With a Free Inspection Report

A reputable contractor's inspection report includes photos, condition notes by section, and a prioritized recommendation: monitor and re-inspect, repair specific items, or replace. You are not obligated to hire the inspector for the work — a good contractor knows that honest assessments generate referrals and repeat business. Use the report to get competitive bids if replacement or significant repair is recommended.

Revolve Construction provides free spring roof inspections across the St. Louis metro. We photograph everything, produce a written condition report, and explain what we found in plain terms. No high-pressure close — just the information you need to make a good decision. Call (314) 400-8006 or schedule your inspection online.

The Spring Inspection Advantage for Insurance Documentation

A spring inspection report does something that a post-storm inspection cannot: it documents your roof's condition before storm season. When a hail event hits in June and you file a claim, the adjuster's job includes distinguishing storm damage from pre-existing wear. A dated spring inspection report showing clean granule coverage, intact flashing, and no pre-existing bare spots makes that distinction straightforward. Without it, an adjuster has legitimate room to attribute a portion of the damage to normal wear and aging. A documented pre-storm baseline closes that debate and consistently results in cleaner, more complete initial insurance scopes.

Spring Inspection Timing: March vs. April vs. May

The optimal spring inspection window in St. Louis is late March through April. By late March, the last significant freeze-thaw cycle has typically passed and any winter damage is fully visible. April gives you time to schedule repairs before the contractor calendar fills with storm-season work, and before summer heat makes attic conditions uncomfortable for inspection. May inspections are fine but risk overlapping with early storm season — if a hail event hits before your inspection, you have lost the pre-storm baseline value. Schedule in March or April for the best practical positioning.

What to Do With a Minor Finding

Not every spring inspection results in a major project recommendation. Common minor findings include a failed pipe boot, a cracked or missing flashing piece, or a section of deteriorated caulk around a skylight. These are maintenance items, not emergencies — but addressing them in spring prevents them from becoming emergency leaks during summer storms. A reputable inspector will be honest about what is a watch item versus what needs immediate attention, and will distinguish the two clearly in the written report. If an inspector recommends full replacement on a roof that shows only minor issues, get a second opinion before committing.

Combining the Spring Inspection With Gutter Maintenance

Spring is also the right time for gutter cleaning and inspection. Winter debris accumulation blocks gutters and causes water to back up at the eave edge, accelerating fascia deterioration and creating conditions that contribute to ice dam formation the following winter. A combined roof and gutter inspection in one visit is efficient: the same contractor can photograph gutter condition, identify any sections that have pulled from the fascia, and clear downspout blockages. Scheduling these together in April sets the entire drainage system up correctly before spring rain season and the following fall leaf drop.
