Ever wonder what a professional roofer actually looks at during a 21-point inspection? Here's the real breakdown of what gets checked and why it matters for your Maricopa County home.

Summary:
A 21-point inspection is a comprehensive evaluation of your entire roofing system, and no, it doesn’t involve a roofer squinting at your house from his truck while eating a burrito. It’s a deep dive into the health of your home. A qualified roofer examines 21 specific areas that are most likely to develop “personality flaws” (read: leaks) after being baked in the Arizona sun for three months straight.
The inspection covers three main zones: the exterior surface, the interior attic spaces, and the “connective tissue” like gutters and flashing. We check for damage, wear, and whether the last guy who worked on it was actually following the rules. In Maricopa County, this thoroughness is the only thing standing between you and a surprise indoor swimming pool during the next monsoon microburst.
Think of it like a physical exam for your house. Your doctor doesn’t just ask if you’re still breathing and send you home with a lollipop; they check your vitals and run tests. That’s what we do for your roof. We’re looking for the early warning signs—like brittle sealants or cracked tiles—that save you from the “expensive surprise” of a full-scale emergency replacement in the middle of July.
Some roofing companies offer “free inspections” that are basically just a high-pressure sales pitch wearing a hard hat. A guy walks around your yard, takes a blurry photo of a bird nest, and tells you that you need a whole new roof. Or worse, they tell you everything is “fine” because they didn’t feel like climbing the ladder that day. You’re left with a false sense of security that’s about as sturdy as a cardboard umbrella.
Surface-level checks miss the places where the real drama starts. If a roofer doesn’t check the attic, they aren’t doing an inspection; they’re taking a stroll. Chimneys, vent pipes, and the underlayment beneath your fancy tiles are the favorite hiding spots for leaks. In Arizona, your tiles might look like they belong on a postcard while the underlayment underneath has been baked into a “forbidden fruit leather” that offers zero protection.
By the time you notice a water stain on your ceiling, you aren’t dealing with a “small leak” anymore—you’re hosting a mold colony and structural rot. A real 21-point inspection digs into the dark corners. We check the attic for “evidence” (like discoloration or damp insulation) and examine every penetration point where water loves to sneak in. Catching a $400 flashing issue today beats paying $18,000 for mold remediation next year every single time.
The process starts on the ground, where we scout the perimeter like we’re looking for a lost cat. We’re checking the “big picture” from multiple angles to see if your roofline is sagging or if your gutters look like they’re trying to detach themselves from the house. This ground-level recon helps us spot obvious red flags before we even set foot on a rung.
Next, we hit the roof—literally. We walk the surface to check your materials up close and personal. Whether you have tile, shingles, or metal, we’re looking for the scars left by the Arizona climate. We look for “bald spots” on shingles (granule loss) and hairline cracks in tiles that are just waiting for the next rainstorm to become a highway for water. If the sealants look like they’ve turned into dry crackers, we know we’ve found a weak spot.
Flashing gets the most scrutiny because it’s the most common place for a roof to fail. Flashing is the metal armor around your chimney and vents, and in 115-degree heat, it can warp and pull away like it’s trying to escape the sun. We also check the gutters to make sure they aren’t filled with enough desert silt to start a small garden. Clogged gutters during a monsoon are basically just “water-storage units” that force moisture back under your shingles.

The 21 points aren’t just a random checklist; they are a hit list of every component that keeps you dry. We examine the roof valleys—where two slopes meet—because those act like high-speed water slides during a storm. If those aren’t clear and sealed, your house is in trouble. We also check the “drip edge,” which is the unsung hero that keeps water from rotting out the wood at the edge of your roof.
We also inspect every single “poke-through” on your roof. Vents, pipes, and skylights are all holes in your house that we’ve tried to cover up with metal and caulk. We make sure the “boots” around your plumbing pipes aren’t cracked and that your skylights aren’t secretly planning to leak onto your dining room table. Every one of these is a potential entry point for a persistent Arizona rainstorm.
Finally, we head into the attic—the place where “energy bills go to die.” We evaluate your ventilation, which is the difference between a comfortable home and a home that feels like it was built inside a toaster. If your attic hits 170 degrees because of poor airflow, it’s cooking your roof from the bottom up. We document every finding with photos so you don’t just have to take our word for it—you can see the “crime scene” for yourself.
In the age of high-tech gadgets, we’ve traded the magnifying glass for infrared cameras. Thermal imaging is like giving your roofer “Predator vision.” It detects temperature differences that the human eye can’t see. Since wet insulation stays cooler than dry materials, a thermal scan can find a hidden leak that hasn’t even made it to your ceiling yet. It’s the ultimate “I caught you” for moisture.
This technology also reveals where your hard-earned AC is leaking out of your house. If you’re paying to cool the entire neighborhood because your roof has thermal gaps, the camera will show us exactly where the money is escaping. It’s particularly useful in Maricopa County because the sun is so intense it can mask standard leaks during the day, but the infrared signature doesn’t lie.
One local homeowner thought their roof was fine until a thermal scan showed a failing vent boot that was slowly dripping into the walls. They fixed it for $450. Their neighbor, who skipped the high-tech check, ended up with an $18,000 bill for structural rot and mold a year later. Thermal imaging turns “I think your roof is okay” into “I know exactly what’s happening with your roof.”
Roofing in Maricopa County is an extreme sport, and our inspections reflect that. While a roofer in Seattle is looking for moss, we’re looking for “sun-fried” components. UV radiation here is so aggressive it can turn flexible sealants into brittle plastic in just a few seasons. We specifically look for signs that your roof’s “sunscreen” (the protective granules or coatings) is wearing thin.
Then there’s the “Thermal Tango.” Your roof expands when it’s 115 degrees and shrinks when it cools down at night. This constant movement can loosen fasteners and cause materials to pull apart at the seams. We check the “tension points” where materials meet, looking for gaps that have opened up like a pair of pants after Thanksgiving dinner. If the roof can’t “breathe” and move, it’s going to crack.
Monsoon season is the final exam for any Arizona roof. We check your drainage systems to ensure they can handle a “sky-is-falling” downpour of two inches in thirty minutes. We look for loose tiles that might become projectiles in 60 mph winds and check the underlayment under your tiles. Even if your tiles look great, if that underlayment is toast, your roof is basically just a very expensive hat that doesn’t actually stop the rain.
Your roof is likely the most expensive “shield” you own. In Maricopa County, ignoring it is like leaving a steak on a hot grill and walking away—eventually, things are going to get burnt. A thorough 21-point inspection catches the small, “cheap” problems before they grow into massive, “I-need-a-loan” problems. It’s the difference between a quick tune-up and a total engine failure. A well-maintained roof in Arizona can last 5 to 10 years longer than a neglected one. That’s an extra decade of not having to worry about a five-figure replacement bill. Plus, if you ever need to file an insurance claim after a storm, having a documented 21-point inspection is like having a “Get Out of Jail Free” card. It proves you’ve been taking care of your property, making the claims process much smoother.
If you’re ready to see what’s actually happening on top of your house, we provide the most detailed 21-point inspections in the Valley. We’ve been helping Maricopa County homeowners stay dry since 1999, using the latest tech and a quarter-century of “sun-baked” experience. Don’t wait for a ceiling puddle to tell you there’s a problem—let us find it first.
