How a JDH Forensic Roof Inspection Actually Works

01 The Answer

JDH's 7-phase forensic roof inspection takes 60-90 minutes on-site across Maryland and Virginia. JDH's HAAG Master Certified team walks every roof, applies the PCC Method to every finding, then emails the complete photo and video report before leaving the property as of May 2026.

Our story →
Most "roof inspections" are a 5-minute walk-around from the driveway. JDH's is a 60-to-90 minute on-roof forensic audit that documents every penetration, every flashing detail, every shingle layer, and every attic ventilation pathway. By the time we leave your property, you have a complete photo and video report in your inbox and a clear recommendation: replacement, repair, or no action at all. About 1 in 4 inspections result in zero work for JDH because we are not paid on commission and the data does not always justify intervention.

Jim authored JDH's 7-phase forensic methodology described on this page and holds HAAG Certified Inspector: Master Level credentials since 2021. Day-to-day, Inspector Manager Brian McClees leads the inspection team that applies this methodology across Maryland and Northern Virginia, with reports used by insurance adjusters, real-estate agents, and lenders.

Why this author

HAAG Master Level is the highest tier of HAAG Certified Inspector credentialing (issued by HAAG Education Inc.), held by the majority of insurance adjuster field staff. Pairing Jim's HCI credential with 1,460+ documented JDH field inspections is what makes the PCC Method actionable instead of theoretical.

The 7-Phase Walkthrough

What Happens, In Order

From the moment we pull up to the moment your written report hits your inbox. Same protocol whether you're scoping a repair, a full replacement, or a claim.

1
BEFORE · 5-10 min curbside

Homeowner Discovery

We start at the curb, not on the roof. Goals shape protocol.

The inspector asks about the roof's history, what you're seeing (active leaks, missing shingles, ceiling stains), what you want long-term (sell in 3 years vs. forever home), and any time or budget constraints. This shapes everything that follows: the same finding can mean a targeted repair for one homeowner and a full replacement for another.

Who: Lead inspector
Your role: Tell us what you've noticed and what you want next
2
BEFORE · 10-15 min perimeter

Property Review

A roof failure is often the symptom of a property-level water problem.

Before climbing, we walk the perimeter. Siding condition, gutter pitch and capacity, downspout discharge points, window flashings, foundation drainage, and trees overhanging the roof all factor into how the roof performs. We don't want to fix the wrong thing.

Who: Lead inspector
Your role: Walk with us if you want; otherwise wait inside

DURING · 30-45 min on roof

On-Roof Forensic Audit

HAAG Master Level inspectors physically walk every accessible roof plane.

Every shingle layer is opened. Every penetration is photographed. Every flashing detail is tested for flexibility. Drone-only or ground-only inspections are explicitly rejected as inferior to physical access. The HAAG Certification Brian holds is the same one carried by most insurance adjusters, so the documentation produced here is structured to satisfy their evidentiary needs.

Your role: Optional — many homeowners watch the live GoPro feed inside

DURING · 10-15 min attic

Interior Verification

What the attic shows is often the truest record of how the roof has performed.

Attic inspection covers exhaust ventilation, intake performance (gable, soffit, ridge), decking integrity and insulation R-values, and any moisture staining that maps to leak entry points found on the roof. Inadequate attic airflow is the #1 hidden cause of premature shingle failure we encounter.

Who: Lead inspector + attic specialist when needed

DURING · Compiled on-site

Documentation

Everything is compiled before we leave your property.

Full photo catalog, narrated GoPro video, thermal imaging, drone footage if used, and a structured written report. The documentation belongs to you (not us) and never expires. You can share it with a second-opinion contractor, an insurance adjuster, a real-estate agent, or a lender, no permission needed.

Who: Inspector + documentation coordinator
Your role: Provide the email where you want the report sent

AFTER · In-driveway review

Recommendations

The 35% Rule decides whether we recommend repair, replacement, or no action.

If a repair costs less than 35% of a full replacement AND solves the problem long-term, we recommend the repair. If forensic data says the roof is performing as intended, we recommend doing nothing (the "no-action protocol"). About 1 in 4 of our inspections result in zero work for JDH. We're not paid on commission, so there's no incentive to oversell. Read the full framework in Roof Repair vs Replacement — How the Decision Is Made.

Who: Lead inspector
Your role: Ask questions; the live review is where decisions actually get made
7
AFTER · Indefinite access

Post-Inspection Access

You keep the documentation forever. Re-inspections are available at any time.

If you decide to wait, the same report serves you in 5 years when something changes. If you decide to use a different contractor, the report still works. The documentation is structured to be usable by insurance adjusters and lenders: pre-loss condition documentation, cause-of-loss findings, and certification of any work performed.

Who: JDH support team
Your role: Save the report email; forward it anywhere you need it
The Branded Framework

The PCC Method

During Phase 3, every finding gets all three components — Problem, Cause, Consequence. The framework is what makes the report usable instead of decorative.

P

Problem (Reality)

What is actually happening on this roof right now, documented with photos. Not what we think might be happening, not what other roofs in the neighborhood typically have — what we can prove with evidence.

C

Cause

Why this failure happened. Age, storm impact, installation defect, ventilation imbalance, or flashing detail. Cause determines whether repair is durable or whether you'll be back here in 18 months.

C

Consequence (Risk)

What happens if this is left alone. Sheathing rot, interior moisture damage, mold, insulation degradation, structural decking failure. Risk determines urgency — and whether insurance will treat it as covered.

The Equipment

Tools On Every Inspection

Not "we look at it." We measure it, photograph it, scan it, and document it.

Physical On-Roof Walk

HAAG Master Level inspectors physically access every roof plane — never drone-only.

Narrated GoPro Video

Live walkthrough recorded for the homeowner record. Every finding spoken on camera.

FLIR Thermal Mapping

Detects moisture pathways and missing insulation invisible to the naked eye.

4K Drone Audits

Aerial coverage of pitches that cannot be safely walked. Supporting evidence only.

HD Snake Cameras

Into ridge vents, soffit cavities, and behind chimney flashings.

Moisture Meters

Quantified decking moisture readings (not "feels damp"). Logged per attic section.

Endoscope Cameras

For wall cavities behind suspect flashing details; non-destructive verification.

High-Res Photography

Catalog-ready images of every finding, geo-tagged to roof location.

Common Questions

Inspection Process FAQs

Specific to the process. For general inspection questions, see the free inspection page.

Why does JDH walk the roof when most contractors use drones? +

Drones see the surface. They don't feel underfoot deflection where decking has weakened, can't lift a shingle to check sealant bond, and can't test flashing flexibility. We use drones as a supporting tool (great for aerial overview and hard-to-reach valleys), but the on-roof walk is what makes the report defensible to an insurance adjuster or a structural engineer. Drone-only inspections are common because they're cheap to deliver, not because they're better. See the methodology comparison in Forensic vs Standard Inspections.

What is the PCC Method and why does it matter? +

PCC stands for Problem, Cause, Consequence. Every finding on the report gets all three. "There's a crack" isn't useful. "There's a crack in the step flashing at the chimney, caused by differential thermal movement between brick and metal, which will allow water entry into the framing within 12-18 months" is useful. It tells you what to do and how urgent it is. The framework also makes our reports usable by insurance adjusters who need cause-of-loss documented.

How is the 35% Rule applied? +

If a repair costs less than 35% of a full replacement and we can document it as a long-term solution (not a band-aid that triggers leaks elsewhere), we recommend repair. Above 35%, or for systems too brittle to safely manipulate without creating new failures, replacement is the more durable answer. The threshold is based on real outcomes from our 1,460+ inspections, not a marketing number. Full breakdown in Repair vs Replacement.

What if you find nothing wrong with my roof? +

You get the inspection report on file and we recommend no action. The "no-action protocol" is explicit: if forensic data shows the roof is performing as intended, we say so. About 1 in 4 of our inspections result in zero work for JDH. We're not paid on commission, so there's no incentive to invent a problem.

Can my insurance company use the report for a claim? +

Yes. Our inspectors hold HAAG Master Certification, the same credential most insurance adjusters carry. The report structure (cause-of-loss, supporting photos, measurement-based degradation findings, pre-loss condition documentation) meets standard adjuster documentation requirements. If your loss is storm-related, we will also meet your adjuster on the roof so nothing gets missed or downgraded during their inspection. See our insurance claims process for more detail.

How long does the full inspection take? +

Plan for 60 to 90 minutes on-site. The on-roof phase is typically 30 to 45 minutes; the rest is property review, attic interior work, documentation, and the live driveway review. You'll have the written report by email before the inspector leaves your property.

What happens if the inspector can't safely walk the roof? +

Steep pitches, ice, snow, recent rain, or compromised decking are all reasons to defer the on-roof phase. When that happens, we either reschedule for safer conditions, use a lift or scaffolding if access is needed urgently, or perform a limited drone-and-attic inspection with that limitation explicitly noted in the report. We don't fake an on-roof inspection from the ground.
