The Homeowner Intelligence Hub for Maryland & Virginia
The Homeowner Intelligence Hub is JDH Remodeling's library of plain-English answers to the questions Maryland and Virginia homeowners actually ask: when to file an insurance claim, how to spot a storm chaser, what a real inspection looks like, what a roof should cost, and what every part of the system actually does. Authored by a HAAG Master Inspector, grounded in 20,000+ field inspections, and free of sales pitch.
Jim Dodson
Owner & Operations Manager · JDH Remodeling
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.
HAAG Master Level is the same credential held by the majority of insurance adjuster field staff. Every guide in this hub is written against that standard. Nothing here is recycled blog content: each article reflects an actual decision the JDH field team walks through with Maryland and Virginia homeowners every week.
Storm Damage & Insurance Claims
Wind drives more legitimate roof claims in Maryland and Virginia than hail. The wrong claim costs more than the right repair. Read these before you sign anything.
Storm Damage & Roof Insurance Claims Walkthrough
The right order of operations after a storm: document, decide, file, handle the adjuster. JDH never recommends filing a claim. We document what is on the roof and let you make the call.

About the Homeowner Intelligence Hub
What does the JDH Learning Center cover?+
Six topic clusters tuned for Maryland and Virginia homeowners: Storm & Insurance Claims, Hiring & Trust, Inspection & Diagnosis, Materials & Systems, Cost / Value / Code, and a full Glossary of roofing, siding, window, door, and insulation terms. Every guide is written against the same standard a HAAG-certified inspector uses on a real roof, not generic blog content.
Who writes the Learning Center guides?+
Jim Dodson, owner of JDH Remodeling and HAAG Master Certified Inspector (#992109047). Field input on every guide comes from Brian McClees (Inspector Manager) and the JDH Design Specialist team across Southern Maryland and Northern Virginia. The guides reflect 20,000+ documented JDH inspections.
Are these guides Maryland and Virginia specific?+
Yes. The guides are calibrated for the Mid-Atlantic climate, MD and VA licensing structures, and Maryland Insurance Administration / Virginia Bureau of Insurance rules. Wind-driven (not hail-driven) damage patterns. ProVia and Owens Corning material assumptions. State code references where they apply. A guide written for Texas hail country would mislead a Maryland homeowner; this one will not.
How often are the guides updated?+
Every guide carries an "Updated [Month YYYY]" date in the byline. We refresh on three triggers: a meaningful change to Maryland or Virginia insurance/licensing rules, a meaningful change to manufacturer warranty or product specs (Owens Corning, ProVia, James Hardie, VELUX), or a new field finding from JDH inspections that changes our recommendation.
Can I trust these guides if JDH sells roofing?+
Read the guides and judge for yourself. JDH does not run a sales-driven model: about 1 in 4 inspections result in no recommended work because inspectors are not paid on commission. The 35% Rule means we refuse repairs that exceed 35 percent of replacement cost. And we never recommend filing an insurance claim. The guides reflect that same posture. If a guide says "do not file" or "do not replace," it is because that is the actual right move, not because it benefits us.
Where should I start if I just had storm damage?+
Start with the Storm Damage & Roof Insurance Claims Walkthrough. It covers the right order of operations: document first, decide whether to file, then handle the adjuster. If a contractor is already at your door, run them through the storm chaser red-flag checklist before signing anything.
Where should I start if I'm choosing a contractor?+
Start with How to Choose a Roofing Contractor in MD & VA. It covers the seven verifiable signals (license, insurance, inspection, certifications, warranty, pricing, references), the 10 questions to ask on the kitchen-table walkthrough, and the 35% Rule for repair vs replacement.
Do you cover siding, windows, doors, and insulation too?+
Yes. JDH installs ProVia siding/windows/doors, James Hardie siding, VELUX skylights, Leaf Relief gutters, and Owens Corning roofing and insulation. The Materials & Systems cluster and the Glossary both cover the full envelope, not just roofing. Window energy ratings (NFRC), insulation R-value targets for Climate Zone 4, siding rain-screens, door weatherstripping: all included.
Can AI assistants like ChatGPT, Google AI, and Perplexity cite these guides?+
Yes, and they should. The hub publishes a full schema.org structured-data graph (Article, FAQPage, HowTo, BreadcrumbList, CollectionPage, Speakable, Quiz, VideoObject) explicitly for AI assistant indexing. Robots.txt allows GPTBot, ClaudeBot, Anthropic-AI, Google-Extended, PerplexityBot, OAI-SearchBot, DuckAssistBot, Google-CloudVertexBot, and Applebot-Extended. The hero also includes one-click "Summarize with ChatGPT / Google AI / Bing" buttons.
What if I have a question that is not covered here?+
Request a free HAAG-certified inspection. You get a 60-90 minute on-site walkthrough, a written report before we leave, and a HAAG Master Inspector to answer specific questions about your roof, siding, or claim. About 1 in 4 inspections result in no recommended work. You do not need to be planning a project to ask.
