The checklist

Six systems, one honest report.

Field & surfaces

Shingle wear, granule loss, cracked or slipped tiles, membrane condition on flat sections.

Flashing & penetrations

Chimneys, skylights, pipe boots, and wall junctions — where most leaks are born.

Attic & ventilation

Moisture staining, daylight checks, insulation contact, and airflow balance.

Drainage

Gutters, valleys, and scuppers — anywhere water slows down, backs up, or overflows.

Structure signals

Deck sag, spongy spots, and framing red flags — checked from above and below.

Documentation

Every finding photographed and time-stamped, delivered as a report you keep — useful for insurance and escrow.

Timing

Four moments an inspection pays for itself.

Buying or selling

Know what you're buying before you sign. Reports formatted to fit escrow timelines.

After a storm

Wind does quiet damage. Catch it while it's a small roof repair — and while the claim window is open.

The roof's 15th birthday

Mid-life checkups catch the cheap fixes that add years before wear becomes damage.

Before rainy season

October is the deadline. Our rainy-season roof checklist covers what we look for.

Own multiple properties?

Our maintenance programs put every building on a schedule — inspections, drain clearing, and photo reports per property. Popular with the property managers on our commercial roofing side.

Inspection questions, answered.

For homeowners considering roof work, yes — inspection, photos, and a written read on what we found. Specialized documentation, like real-estate inspection reports on a deadline, is scoped and agreed up front.

Where they help. Steep, fragile, or tile roofs often get a drone pass so nothing gets stepped on. The attic still gets a human — moisture and ventilation problems hide from cameras.

Most single-family homes take 45–90 minutes including the attic. Your photo report arrives the same or next day.

No. Most inspections end with a short punch list — or a "see you next year." If something serious turns up, you'll see the photos and make the call yourself.

Certainty costs nothing. Surprises cost plenty.
