What a Roof Inspection Actually Looks At
A roof inspection is a top-to-bottom read of your roofing system, not a glance from the driveway. We photograph what we find and note the age of every layer.
Every inspection ends in a written report you can use for an insurance claim, a home purchase, or a repair plan.
Where a tile or metal field is too steep to walk, drone imagery fills the gap. An infrared scan from the attic side and a moisture meter at suspect spots tell us whether water is moving beneath the surface.
- Algae-stained, blistered, buckled, cracked, or curled shingles get photographed first, and granule loss piling up in the gutter usually confirms end-of-life wear on the top layer.
- A leaky ceiling almost always traces back to chimney flashing, step flashing, or counter-flashing, since those joints fail years before the shingle field around them does.
- The pipe boot and vent boot around plumbing stacks crack under UV long before the surrounding rooftop, and resealing one costs far less than the drywall it soaks.
- A clogged ridge vent, a painted-shut soffit vent, a dead attic fan, or damp insulation will bake the underside of your roof deck and shorten every shingle above it.
- Water wicks behind a failing drip edge and rots the eave, so we check fascia, soffit, gutter, and downspout runs for soft wood and rust streaks.
- Valley, ridge cap, and rake intersections get hand-checked for nails that backed out, cracked pipe flashing, caulk that peeled, and sealant that pulled away from the substrate.
Materials We Read Before We Quote a Roof Estimate
A roof estimate means nothing until we know what material is up there, because roofing systems age at wildly different rates. Here is how we sort them.
- Asphalt shingle roofs get identified by type, since three-tab shingle, architectural shingle, and discontinued organic-mat product all age on different clocks.
- Wood shake and cedar shake get probed for rot and decay, because Phoenix heat dries them brittle and split shakes send water straight into the underlayment.
- Slate, clay tile, and concrete tile crack from foot traffic far more often than from heat, so we walk them on foam boards.
- Metal panel, standing-seam panel, and corrugated panel hide corrosion at the fastener and washer, so we test screws across a full square.
- Membrane roofs get read by chemistry, since TPO, EPDM, PVC membrane, built-up roof, and modified bitumen each fail differently and ponding water means something different on each one.
- Underlayment matters more than most people expect. Synthetic underlayment and an ice-and-water shield at the eave replaced the old roofing felt and tar paper on nearly everything we open.
Ice dam removal and steam ice work are not services we offer here, because Maricopa County does not produce the freeze-thaw cycles that build those problems.
The Deck, the Frame, and the Detail Work
Everything above the deck is only as good as what holds it. A roofer who never climbs into the attic is guessing about half the roof.
- Decking, whether plywood, OSB, or old board sheathing, gets checked for soft spots and rot with a moisture meter and an infrared scan.
- Below that we record truss, rafter, joist, and ridge beam condition, because a sagging roofline usually starts at the frame rather than the shingle.
- Chimney, skylight, dormer, and parapet details get their own photos, along with hip, gable, verge, apron flashing, and boot flashing.
- Purlin, batten, and counterbatten spacing matters on metal roofing, and a corroded substrate under a standing-seam panel means replacement, not a recoat.
- Scupper and coping on flat sections, plus canopy, awning, overhang, mansard, and gambrel transitions, each leak in their own particular way.
- Old tar, pitch, asphalt, and bitumen surfaces earn a coating only when the deck is sound. Roof cement, mastic, adhesive, and caulk are patch materials, not waterproofing, and we say that plainly.
Tools, Safety, and What the Findings Cover
Our methods follow the documentation standards used by HAAG and IICRC-certified inspectors. Every item lands in a written report with photo evidence, not a verbal summary.
- A ladder, scaffold, or safety harness goes up on every roof inspection, ours or anyone else's, because a damaged roof is not worth a fall.
- Repair days bring a roofing square, nail gun, air compressor, pry bar, and roofing shovel; a torch only appears where membrane seams need heat.
- A dumpster sits in the driveway for tear-off debris, and we tarp walls and landscaping before the first shingle comes off.
- Weatherproofing finishes with a vapor barrier tie-in at the eave and proper flashing laps, while anchors and snow guards are rarely needed in this climate.
- Local building code governs deck attachment, nailing pattern, and ventilation minimums, and we flag anything that will not pass an inspection.
Emergency repairs after monsoon wind or hail get scheduled ahead of routine work, and a damaged section can usually be tarped the same day you call 6025330488.
As a licensed and insured Phoenix roofing contractor, we tell you when a patch is enough and when replacement is the honest answer.
