A roof inspection is one of those things homeowners rarely think about until there’s a problem — and by then, the problem is usually bigger and more expensive than it had to be. The good news is that a proper inspection is straightforward, non-invasive, and (with Green Slate Roofing & Siding) free.
If you’ve never had your roof professionally inspected, this guide explains exactly what happens during one, what a good inspector actually checks, and the situations where scheduling an inspection is well worth your time.
Why a roof inspection matters
Your roof is a system, not just a layer of shingles. Flashing, underlayment, ventilation, gutters, and the deck underneath all work together to keep water out. A small failure in any one of them can lead to leaks, rot, and interior damage — often long before you’d notice it from inside the house.
On Colorado’s Front Range, roofs take more abuse than most: intense UV at altitude, hail, wind-driven storms, and constant freeze-thaw cycles. An inspection catches the small issues while they’re still cheap to fix.
What happens during the inspection
A thorough inspection has a few distinct parts. Here’s the typical flow.
1. The conversation first
A good inspection starts on the ground with a quick conversation. When was the roof installed? Have you noticed any leaks, stains, or drafts? Was there a recent storm? This context tells the inspector where to look closely.
2. The exterior, up close
The inspector accesses the roof safely and examines the actual surface — something you can’t do reliably from the ground. They look for:
- Shingle condition — cracking, curling, blistering, granule loss, and hail bruising
- Flashing around chimneys, skylights, vents, and in the valleys, where most leaks actually begin
- Roof penetrations — vent boots, pipe collars, and seals that dry out and crack over time
- Ridges and eaves for lifting, wear, or storm damage
- Gutters and downspouts for granule buildup and proper drainage
If your concern is storm-related, this is where hail and wind evidence gets documented. Our hail damage roof repair page explains what those signs look like.
3. The attic and interior, when accessible
Some of the most useful information is found inside. From the attic, an inspector can spot moisture, daylight coming through the deck, inadequate ventilation, and early signs of a leak that hasn’t yet reached your ceiling.
4. Documentation
This is the part that separates a real inspection from a sales pitch. The inspector photographs what they find and puts together a plain-language summary of the roof’s condition. You get a clear record — not pressure.

5. The walkthrough
Finally, the inspector walks you through the findings. A good one explains what’s normal wear, what needs attention soon, and what (if anything) is urgent — and answers your questions in language that actually makes sense.
When should you schedule a roof inspection?
You don’t need an inspection every month, but these are the moments when one pays for itself:
- After any significant storm — especially hail or high wind. See our storm damage roofing page for what to do after a storm.
- When buying or selling a home — so the roof’s condition is a known quantity, not a surprise.
- Before your warranty or roof reaches the end of its expected life — to plan ahead instead of reacting to a failure.
- When you notice warning signs — ceiling stains, granules in the gutters, daylight in the attic, or a sudden spike in energy bills.
- Every few years as routine maintenance — particularly for older roofs or homes surrounded by trees.
A quick “should I call” checklist
Schedule an inspection if you can check any of these:
- A storm recently passed through your area
- You’ve seen water stains or damp spots indoors
- Your roof is more than 10–15 years old and hasn’t been looked at
- You’re buying or selling the home
- You see shingle granules collecting in the gutters
- There’s visible sagging, missing shingles, or damaged flashing
What an inspection is not
An honest inspection isn’t a pretext to sell you a new roof. Plenty of inspections end with “your roof is in good shape — see you in a couple of years.” When work is genuinely needed, a trustworthy contractor shows you the documented evidence and explains your options, including the option to simply repair rather than replace.

Frequently asked questions
Is a roof inspection really free? Yes. Green Slate Roofing & Siding provides free, documented roof inspections across the Denver metro and Front Range, with no obligation.
How long does a roof inspection take? Most residential inspections take about 30 to 60 minutes, depending on the size and complexity of the roof and whether attic access is included.
Do I need to be home for the inspection? It helps to be home for the initial conversation and the walkthrough, but the exterior assessment can be done without you inside. We’ll always review the findings with you afterward.
How often should I have my roof inspected? Every few years as routine maintenance, and any time after a major storm or when you notice warning signs like leaks or granule loss.
Will you walk on my roof? When it’s safe to do so, yes — that’s how we assess the actual surface condition. If conditions are unsafe (ice, steep pitch, storm damage), we use other methods and let you know.
Take the guesswork out of your roof
A free inspection is the simplest, lowest-risk way to know exactly where your roof stands — before a small issue becomes an expensive one. Whether a storm just passed through or you just want peace of mind, it’s worth the hour.
