How to Choose a Roofing Contractor in Maryland & Virginia

01 The Answer

Choosing a roofing contractor in Maryland or Virginia comes down to seven verifiable signals: state license, insurance, inspection methodology, manufacturer certification, warranty scope, line-item pricing, and review depth. A HAAG-certified inspector sees evidence on your roof an uncertified one misses entirely.

Our story →
The difference between two roofing estimates is rarely the price gap. It is a full replacement in three to seven years, an insurance carrier that walks away from a claim, and a "lifetime" warranty that vaporizes the day the company changes its name. The seven signals on this page are not a checklist. They are a defense — verifiable, documented, and the same ones we'd want on our own roof.

JDH Remodeling is a Southern Maryland and Northern Virginia roofer founded in 1986, led by a HAAG Master Inspector, that recommends what each roof actually needs — whether that is a repair, a replacement, or sometimes nothing at all — instead of what makes them the most money. Day-to-day, Inspector Manager Brian McClees leads the field team that applies the PCC Method across Maryland and Northern Virginia, with reports used by insurance adjusters, real-estate agents, and lenders.

Why this author

HAAG Master Level is the same credential held by the majority of insurance adjuster field staff. Pairing Jim's HCI credential with 20,000+ documented JDH field inspections is what makes the seven signals on this page actionable instead of theoretical.

The Seven Signals

What Actually Separates a Real Roofer From a Storm Chaser

Every signal below is verifiable in 30 seconds. Use them on every estimate, every contractor, every time.

1
Licensing Verify in 30 sec · MHIC + VA contractor lookup

Why "licensed roofer" means less than you think

In Maryland, an MHIC license means you are allowed to enter into a home improvement contract. That is it. In Virginia, the Class designation (A, B, C) caps annual volume. Neither state vets, certifies, or licenses roofers.

That gap is why every other signal on this page matters. The license is the floor. Everything that protects you on a real roofing project sits above it.

Insurance Verify in 1 hour · Ask for the COI

Insurance, liability & risk transfer

Both Maryland and Virginia have minimum coverage requirements for general liability only — $50,000 — which is not enough coverage for a legitimate roofer to operate behind. Neither state mandates workers compensation for residential roofing. If an uninsured roofer's employee gets hurt on your roof, the liability can come back to you as the homeowner.

JDH carries $8M in combined general liability and workers compensation. Most regional roofers carry under $1M.

The question that flushes out an underinsured contractor

"Can I see a copy of your COI?" A legitimate contractor has it on hand or can email it within the hour. An underinsured one stalls, makes excuses, or sends one that conveniently doesn't list workers comp. JDH sends the certificate of insurance with every estimate, before you have to ask.

Inspection Quality Verify on first visit · Watch what they carry

What a real inspection actually looks like

We are basically experts at assessing damages, specifically from storms. The HAAG Master Level credential is the same one held by the majority of insurance adjuster field staff, which means our damage findings on a JDH inspection are produced to the same evidentiary standard the adjuster uses themselves.

Roofers live in a trust hole with homeowners. We are roofers and we are considered sales guys. So JDH took the approach of being more like doctors. Jim Dodson, HAAG Master Inspector

That is the entire reason the PCC Method exists. Instead of pointing at a roof and selling a replacement, a JDH Design Specialist uses diagnostic tools to identify what is actually wrong, why it happened, and what happens if it is left unchecked. No scare tactics. No sales quotas.

Repair vs Replace Ask · "What's your written decision rule?"

The 35% Rule

JDH will not repair a roof if the repair cost is 35 percent or more of the replacement cost. The number was chosen because the team didn't think it was ethical to charge someone more than 35 percent to repair a roof they would have to replace soon anyway. That is the rule, written down, applied to every estimate.

We didn't think it was ethical to charge someone more than 35 percent to repair a roof they would have to replace soon anyway. The 35% Rule

What it looks like on a real roof

A homeowner had a roof right on the line. Replacement was around $25,000 and the roof was only 10 years old. JDH told the homeowner the truth and gave them the option. The repair cost (about 35 percent of replacement) was used as a deposit, and the rest was financed for 2 years no interest. The homeowner's price didn't go up later and they didn't waste money on a repair that wouldn't last.

The PCC Audit ends with a recommendation, not a sale. About 1 in 4 inspections result in no recommended work because we are not paid on commission.

The Digital Analysis — what the homeowner actually gets

When JDH inspects a roof using the PCC Audit Method, the homeowner doesn't get a few pictures and an estimate stapled to a folder. They get a Digital Analysis: an actual video the homeowner watches first, with every problem the Design Specialist found narrated on camera as Problem, Cause, Consequence, supported by on-roof GoPro footage, thermal imaging, and the rest of the inspection documentation.

Warranties Read the document · Not the word

Three things people call a warranty

They are not the same thing. Materials warranty comes from the manufacturer and covers shingle defects. Workmanship warranty comes from the contractor and covers installation errors. "Lifetime" in a sales pitch usually means lifetime of the warranty, not lifetime of your ownership.

JDH's in-house workmanship warranty is 5 years. Extended manufacturer-backed workmanship warranties are available through Owens Corning when you choose JDH; we walk you through the options at your inspection so you know what is covered before you sign. JDH installs Owens Corning shingles exclusively, so the materials and workmanship sides come from the same documented system.

VELUX skylights — the manufacturer warranty pass-through

VELUX certification applies only to skylights. JDH is a VELUX Certified Installer, which means we can warranty the skylight itself, not just our installation of it. A non-certified roofer cannot do that, even if they happen to install a VELUX skylight, because the manufacturer warranty pass-through is tied to installer certification.

Pricing Transparency Watch · The three red flags below

Three pricing patterns that tell you to walk

Watch for any one of them. Any one of these is reason enough.

1. "We work with insurance companies"

A contractor who refuses to give you a price because they "work with insurance companies." A real roofer can quote a job. A contractor hiding behind your insurance carrier is hiding something.

2. Today-only pricing

If the price disappears at the end of the visit, the price was never real to begin with. Legitimate estimates carry a written validity window of at least 30 days.

3. Vague material descriptions on the contract

Generic descriptions like "architectural shingles" or "premium underlayment" instead of the specific brand, product line, and color. If it isn't named on the contract, it isn't going on your roof.

7
Storm Chasers Refuse to sign · Any day-of work authorization

The door-knocker trap

A guy knocks on your door claiming there was a big storm that no one else remembers. He has you sign a work authorization or a contingency agreement that he claims costs you nothing unless insurance approves the roof.

Insurance doesn't approve the roof. Now you're married to this contractor and you owe them a lot of money. And to make it worse, your roof was fine before they got there. Maybe a little old. But now that your insurance company came out to look at it, they know your roof is old, and they send you a letter saying you need to replace it or they're going to drop your policy.

Why this is so common in our market

Southern Maryland and Northern Virginia is a very unique market. You can't throw a rock without hitting a body of water, and all those peninsulas create a lot of wind. Hail isn't frequent here the way it is in other parts of the country. So out-of-state contractors who are calibrated for hail-driven claims miss what actually drives roof failure in this region, which is wind. That gap is the opening storm chasers exploit.

The Method

The PCC Method, Explained

The diagnostic framework JDH uses on every inspection. Problem. Cause. Consequence. Same logic a physician applies to a body, applied to your roof.

P

Problem

What is actually wrong with the roof. Documented with thermal, drone, and on-roof imagery. Not interpreted, not editorialized — recorded as it is.

C

Cause

Why it happened. Wind uplift. Flashing failure. Decking rot. Improper nailing pattern. The diagnostic step that separates a forensic inspection from a sales walk-around.

C

Consequence

What happens if it is left unchecked. Honest timeline for each finding. Sometimes the answer is "nothing for five years." That's still the answer.

Every problem identified gets its own PCC breakdown. The Digital Analysis is more than a few pictures and an estimate. It is a total expert view of the roof.

PCC Audit Method, JDH
What Every Design Specialist Carries

The Equipment Most Roofers Don't Have

If a contractor shows up with a ladder and a clipboard, that's the entire inspection. JDH inspectors carry these on every roof.

Thermal Imaging

FLIR cameras find moisture damage and heat-loss patterns invisible to the naked eye.

Snake Cameras & Endoscopes

For confined-space penetrations, vent stacks, and tight chimney flashings.

Moisture Meters

Quantitative wood-moisture readings on decking, sheathing, and trim. Numbers, not guesses.

GoPros & Drones

On-roof video documentation. Aerial perspective on chimney, ridge, and steep-slope work other crews skip.

HAAG Shingle Gauges

The same measurement tools insurance adjusters carry. Used for hail and wind damage substantiation.

Temperature & Pitch Gauges

Surface temperature affects shingle behavior. Pitch determines installation requirements per code.

Roof Hooks & Pitch Hoppers

The safety gear that lets us walk every roof, not just the easy ones. Most roofers skip steep slopes.

Cougar Paws & Cleats

Steep-slope footwear used by professional roof inspectors. Doubles as proof the contractor knows how to handle the roof.

Frequently Asked

Choosing a Roofer FAQ

Are you licensed to enter home improvement contracts in Maryland and Virginia?+

JDH holds Maryland Home Improvement Commission license #137491 and Virginia Class A contractor license #2705192986. Both are continuously active and verifiable on the respective state licensing databases. "Licensed" is not the same as "verified" — confirm the number, not the claim.

What manufacturer certifications do you hold?+

Owens Corning Platinum Preferred Contractor, Owens Corning Top of the House Certified, ProVia Platinum Dealer, VELUX Certified Installer, and VELUX Skylight Specialist. Every certification is verifiable on the manufacturer's website.

Can you show proof of general liability and workers' compensation?+

JDH carries $8 million in combined general liability and workers' compensation. We send the certificate of insurance directly with every estimate. If a contractor cannot produce a certificate the same day you ask, that is a red flag.

What does your inspection include?+

Every Design Specialist on a JDH inspection carries thermal imaging, snake cameras, endoscopes, moisture meters, GoPros, HAAG shingle gauges, temperature guns, pitch gauges, and drones. The inspection follows the PCC Method — Problem, Cause, Consequence — and the finding is delivered to you as a narrated Digital Analysis video.

How do you decide between repair and replacement?+

JDH applies the 35% Rule. If a repair will cost 35 percent or more of replacement, we will not repair it — because charging more than that to fix a roof you'd have to replace soon anyway isn't ethical. Below 35 percent, we repair. The decision logic is the same on every estimate.

What warranties apply to materials versus workmanship?+

Materials warranty comes from the manufacturer (Owens Corning) and covers shingle defects. Workmanship warranty comes from the contractor — JDH's in-house is 5 years, with extended warranties available through Owens Corning. "Lifetime" in a sales pitch usually means lifetime of the warranty, not of your ownership. Always read the document.

Is pricing fixed by line-item scope?+

Every JDH estimate is itemized: materials, labor, tear-off, disposal, decking-replacement allowance, permits, and warranty registration as separate line items.

Is the price valid for longer than a day?+

JDH estimates carry a written 3-month validity window. "Sign today only" is the single most common high-pressure tactic and is by itself a reason to walk away.

Can I speak directly with past customers?+

Yes. JDH provides three references from jobs within five miles of your address, completed within the last 12 months. We give you $100 off for every reference you call from our reference book — and we have thousands.

Who is accountable if something goes wrong?+

Jim Dodson, the owner. JDH is family-owned since 1986. If a concern arises after the job, someone is on site within 2 business days.
