Before you call a roofing contractor in St. Louis for an inspection, you need to understand what you are actually dealing with on your roof, what information to gather, what questions to ask, and what red flags to watch for. Homeowners who go into this process informed get better service, more honest assessments, and far fewer surprises when the report comes back.
This guide is not about the inspection itself. It is about YOU, the homeowner, and everything you should know and do before a contractor ever sets foot on your property.
Why Your Preparation Matters More Than You Think
Most St. Louis homeowners call a roofing contractor the moment they notice something wrong, and they do so without any background information ready. No roof age, no repair history, no idea what materials are on the roof, and no list of questions prepared. This puts the contractor in complete control of the conversation from the first phone call.
A contractor who sees an unprepared homeowner may not take the time to explain what they find in detail. They may present the most expensive solution first, knowing you have nothing to compare it against. This does not mean all contractors are dishonest. In fact, St. Louis has a strong community of reputable roofing companies. But your own preparation is what turns a good contractor into a great experience for you.
Knowing your roof’s basic history, doing a safe ground level visual check yourself, and walking in with the right questions gives you control over one of the most significant home maintenance decisions you will make.
Step One: Know Your Roof Before Anyone Else Does
The first thing a prepared homeowner does before calling anyone is gather the basic facts about their roofing system.
Find out how old your roof is. If you bought the home, this information may be in your closing documents, your home inspection report, or your homeowners insurance policy. Asphalt shingles in St. Louis typically last between 20 and 30 years depending on the brand and how the roof has been maintained. A roof under ten years old with no storm history is a very different situation from a roof that is 18 years old in a neighborhood like Chesterfield or Wildwood that takes regular hail hits every spring.
Pull together any previous repair records. If you had work done on the roof in the past, knowing when it was done, who did it, and what was repaired gives the new contractor critical context. It also helps you spot whether someone is telling you to repair something that was already addressed recently.
Know your roofing material. Most St. Louis homes have asphalt shingles, but older homes in historic neighborhoods like Soulard, Benton Park and the Central West End sometimes have slate, modified bitumen on flat sections, or clay tile on dormers. Knowing your material type upfront helps you verify that the contractor you call actually has experience with your specific roof.
Locate your homeowners insurance policy. Before the contractor arrives, understand what your deductible is, whether you have a separate wind and hail deductible, and what your policy says about storm damage claims. Many Missouri homeowners discover for the first time during a claim that their policy carries a percentage-based wind and hail deductible rather than a flat dollar amount. Carriers like State Farm, Shelter Insurance and American Family Insurance are common in the St. Louis area, and their claim processes differ in important ways.
Step Two: Do a Safe Ground Level Check Yourself
You should never climb onto your own roof. The risk of injury is real and the liability is yours entirely. But you can learn a great deal from the ground with a pair of binoculars and fifteen minutes of your time.
Walk the perimeter of your home and look at the roof from each side. Here is what to pay attention to:
Shingle condition. Look for areas where shingles appear darker, where edges are lifting or curling, or where patches of shingles look noticeably different in color from the surrounding area. Discoloration often indicates algae or moisture intrusion. Missing shingles are obvious but broken or cracked ones require binoculars to spot clearly.
Granules in your gutters. Walk to each downspout and look at what has accumulated at the base. A heavy deposit of grit that looks like coarse sand or gravel is granule loss from your asphalt shingles. Some granule shedding is normal, especially on newer roofs. But if your gutters are full of it, your shingles are losing their protective coating and nearing the end of their life.
The roofline itself. Look at the ridge line across the peak of your roof from a distance. It should be straight and level. Any sagging, dipping or waviness suggests a structural concern that goes beyond a simple repair.
Visible flashing around chimneys and vents. If you can see the chimney from the ground, look at the metal flashing around its base where it meets the roof surface. Rust staining, gaps or sections that appear separated from the masonry are warning signs worth noting before your contractor visit.
Inside your home. Go into your attic with a flashlight before you call anyone. Look at the underside of the roof deck for water stains, dark spots, streaks of dried moisture and any areas where daylight is visible. Check whether your attic smells musty. Mold in an attic develops when moisture has been present long enough to support biological growth, and it tells you that whatever is leaking has been doing so for some time.
Write down everything you observe. This is your personal inspection record, and it gives you a foundation for evaluating what the contractor tells you.
Step Three: Understand the Difference Between Urgent and Routine
Not every roof situation in St. Louis is an emergency, and understanding which category you fall into shapes how you approach the contractor call.
Signs that your situation is urgent:
Water is actively dripping or staining inside your home during or after rain. A tree or large branch has made contact with your roof. You can see daylight through the attic deck. Your ceiling is bulging or soft to the touch in any area. You experienced a severe storm and your neighbors are all having contractors out.
In these cases, call the same day. A reputable contractor in St. Louis can typically get an inspector out within 24 to 48 hours for urgent situations, and some offer same-day emergency assessments.
Signs that your situation is routine maintenance:
Your roof is approaching ten years old and has never been professionally inspected. You noticed granule loss in the gutters during a recent rain. Your energy bills have increased and you want to rule out ventilation issues. You are planning to list your home for sale in the next six to twelve months.
Routine inspections can be scheduled in advance and are best done in spring before severe storm season begins, or in fall before winter weather arrives in Missouri.
Step Four: Vet the Contractor Before You Book
This is the step most homeowners skip entirely, and it is the most important one.
Verify local licensing. Missouri does not issue a single statewide roofing contractor license, which means anyone can technically call themselves a roofer without formal state credentials. However, St. Louis City and most St. Louis County municipalities require local contractor registration and licensing. Ask any contractor you call for their local license number and verify it through the city or county municipality before scheduling. This single step eliminates the vast majority of unqualified contractors.
Confirm insurance coverage. A legitimate roofing contractor in St. Louis carries two types of insurance. General liability coverage protects your property if it is damaged during the inspection or repair process. Workers’ compensation covers the crew members themselves if anyone is injured on your roof. If a contractor cannot provide current certificates for both, do not let them onto your property under any circumstances. Without workers’ compensation in particular, any injury on your property could become your financial and legal responsibility.
Look for manufacturer certifications. The roofing industry has meaningful contractor credentials that go beyond general licensing. GAF Master Elite status, Owens Corning Platinum Preferred designation and CertainTeed SELECT ShingleMaster certification are awarded to contractors who meet rigorous training, installation and customer service standards. These contractors are also authorized to offer extended warranty coverage that non-certified installers cannot provide. Ask directly whether the contractor holds any manufacturer certifications.
Check their physical presence in St. Louis. After major storms, out-of-state roofing crews sometimes move through St. Louis neighborhoods looking for work. These storm chasers may do adequate work, but they will not be available when you need a warranty issue addressed six months later. A contractor with a verifiable St. Louis County business address, an active BBB profile and documented local reviews is a far more accountable choice.
Read reviews carefully. Star ratings alone tell you almost nothing. Read the actual written reviews and look for patterns. Pay attention to how the company handles complaints and whether they respond professionally to negative feedback. A contractor with 4.8 stars and 400 reviews who responds thoughtfully to criticism is far more trustworthy than one with 5 stars and twelve reviews.
Step Five: Prepare the Right Questions for the Call
When you call a roofing contractor for the first time, you are evaluating them as much as they are gathering your information. Here are the questions every St. Louis homeowner should ask before booking an inspection appointment.
Are you licensed and insured to work in St. Louis County or St. Louis City? A confident, legitimate contractor answers this immediately and offers to send you their certificates before arrival.
Do you use subcontractors for your inspections or repairs? This is important because subcontractors may not carry the same credentials or insurance as the primary contractor. Know who is actually coming to your home.
Will I receive a written inspection report with photos? A verbal summary after an inspection is not enough. You need documented findings with timestamped photographs, especially if an insurance claim is involved.
How long have you been operating in the St. Louis area? Local tenure matters in Missouri’s climate. A contractor who has been working in St. Charles, Kirkwood, Ballwin and the surrounding areas for ten or more years understands how Missouri weather specifically degrades different roofing materials.
Will you walk me through your findings in person before you leave? The best contractors take time to explain what they found in plain language and answer your questions on site, not just in a report delivered the next day.
Do you have references from recent jobs in my area? Ask for references from jobs completed within the past six months in your neighborhood or nearby. Follow up with at least two of them.
Red Flags That Should Make You Walk Away
Knowing what to look for on the positive side is only half of the equation. There are behaviors that should immediately remove a contractor from consideration.
Any contractor who asks for large cash payments upfront before any work is completed is a serious concern. Standard industry practice in St. Louis involves a deposit of no more than one third of the total project cost before materials are ordered, with the remaining balance paid upon satisfactory completion.
A contractor who pressures you to sign a contract on the spot, particularly after a storm event, is not working in your interest. Reputable contractors in Missouri understand that homeowners need time to gather multiple estimates, verify credentials and review contract terms without being rushed.
Be very cautious of any contractor who claims they can make your insurance deductible disappear or promises to cover it through some kind of arrangement. This practice violates Missouri insurance laws and can result in claim denial and legal complications for the homeowner.
If a contractor’s estimate comes in dramatically lower than every other quote you receive, treat that as a warning rather than a win. Significant undercutting often reflects the use of inferior materials, plans to cut corners during installation, or an absence of the insurance coverage that drives up costs for legitimate contractors.
What to Have Ready When the Inspector Arrives
Once you have booked with a vetted contractor, prepare your home and information for the day of the inspection.
Have your homeowners insurance policy information available. If the inspector finds storm damage, they may ask about your carrier and policy number on the spot to begin helping you with documentation.
Clear any access points to your attic. The interior portion of a thorough inspection requires getting into the attic space, and having the area accessible saves time and ensures nothing gets missed.
Make a note of any interior areas where you have noticed water stains, soft spots or discoloration on ceilings. Walk the inspector through these areas before they go up onto the roof. Interior symptoms often point directly to the exterior source of a problem.
Note the last significant storm that affected your area. If St. Louis received a hail event or high wind storm in the past year, that date is valuable information for the inspector and for any subsequent insurance documentation.
Frequently Asked Questions
Do I need to be home during a roof inspection in St. Louis?
It is strongly recommended. Being present allows you to ask questions in real time, walk through findings with the inspector, and provide context about any interior symptoms you have noticed. While some contractors will conduct an inspection without you present, you get significantly more value from the visit when you are there.
How many estimates should I get before choosing a contractor?
Get at least three fully itemized estimates. This gives you a realistic sense of market pricing in St. Louis and makes it much easier to identify any outliers, whether suspiciously low or unreasonably high.
Is a free inspection from a contractor trustworthy?
Free inspections from licensed, reputable St. Louis contractors are generally honest and thorough. Reputable companies build their business on long-term relationships, not one-time sales. However, always verify credentials before any inspection regardless of whether it is free or paid.
What if two contractors disagree on what my roof needs?
Get a third opinion. Disagreements between inspectors happen, especially on roofs that are borderline in terms of age and condition. A third assessment from a contractor with no knowledge of the previous two opinions usually clarifies the situation considerably.
Can I wait until after winter to schedule my inspection?
If there is no active leak or urgent damage, waiting until spring is acceptable. However, entering winter with an uninspected roof that may have sustained fall storm damage is a risk, particularly in Missouri where ice dams, snow load and freeze-thaw cycles can rapidly worsen existing weak points.
A roof inspection in St. Louis, USA is one of the most straightforward steps a homeowner can take to protect a significant financial investment. But it only delivers full value when you walk into the process prepared. Know your roof, vet your contractor, ask the right questions, and watch for the warning signs that separate professional service from opportunistic shortcuts. The time you spend on preparation before the call is paid back many times over in clarity, confidence and protection for your home.
