Four things in your hands before we leave the driveway.

Most "free inspections" are a ladder, a look and a quote. Ours produces a document. Keep it, share it, use it to get a second opinion — we'd rather you did.

Photo report

75–150 photos: overall, detail and close-up of every slope, penetration and the attic. Time-stamped.

Hunter-Gatherer Report™

The 32-point checklist in three sections: roof surface (13), attic and ventilation (13), water flow (6). One page, front and back, signed by you.

Measurements

Squares, pitch, penetrations, decking condition — the numbers any honest quote is built on.

Your Roof Grade

A single letter, with the score behind it and a plain-English verdict: leave it, repair it, or replace it. Free inspection + photo report + measurement + proposal, yours to keep.

Six enemies of every roof. We check for all of them.

Water, wind, heat, sun, time and hail — plus the two most contractors skip: how it was built and how it breathes.

Leaks & moisture

Pipe boots, flashings, valleys, small leaks that only show in heavy rain, attic moisture.

Lift & creep

Lifted tabs, broken seals, missing shingles, nail pops, ridge caps.

Ventilation

Intake and exhaust, attic temperature, insulation contact, fans venting where they shouldn't.

UV & granule loss

Bald spots, cracking, brittle boots, blistering.

Age & wear

Where the roof is in its life, and what that means for repair vs replace.

Impact damage

Test squares on every slope, bruising, fractured mat, soft metals as the tell.

Construction issues

Improper installation by the previous contractor, code deficiencies, manufacturer-installation violations, incorrect flashing, ventilation mistakes and other workmanship issues.

Hidden problem areas

The attic tells half the story. We go up there. Most contractors never do.

A grade that tells you exactly where your roof stands.

The grade comes from written inspection criteria, not an opinion: 32 points scored in the attic and on every slope, with the photographs and measurements attached, so you know what it means and can show it to anyone.

How the grade is set.

The Hunter-Gatherer Report checks 32 points in three sections: the roof surface and materials (13), the attic and ventilation (13), and water flow (6). Every point is marked yes or no for action needed. The number of points that need action sets the letter, and the report shows which ones and why, with photographs.

GradePoints that need actionWhat the report saysIn plain words
A0Performing as designedNothing needs action. The roof is doing its job, and we set a date to look again.
B1 to 4Minor repairs neededA few repairs, each one named and photographed. The rest of the roof is doing its job.
C5 to 10At riskSeveral problems at once put the roof at risk. Repair or replacement is weighed point by point.
D11 to 15High riskProblems across the roof, and a high risk of leaks and damage inside.
F16 or moreUrgent action recommendedHalf the points or more need action. Act soon.

The count alone sets the letter: no plus or minus, and no opinion added on top.
