Asphalt Shingle Roof Cost, From the Owens Corning Platinum Preferred Contractor

A typical asphalt shingle roof on a 20-square (about 2,000 square foot) home runs $11,500 to $16,500 installed by JDH, at $575 to $825 per square. Owens Corning Oakridge installs land $575 to $650 per square; Owens Corning TruDefinition Duration installs land $700 to $825 per square. Larger roofs, complex hip-and-gable lines, decking that needs broad replacement, or a coastal-grade Duration Storm upgrade can push beyond that range; small one-story ranches with simple geometry can land at the bottom. The forensic inspection is free and produces the actual number for your roof.

Two reasons. First, shingle line: Oakridge sits at the lower end, TruDefinition Duration sits at the upper end. Second, the Owens Corning Total Protection Roofing System accessories that go under the shingle. Entry-tier installs run RhinoRoof as both underlayment and ice-and-water shield. Upper-tier installs use ProArmor synthetic underlayment plus WeatherLock self-adhered ice-and-water shield at eaves, valleys, and penetrations. The shingle on the curb can look similar between tiers; the layers underneath are what earn the OC Platinum Protection warranty and decide whether the roof lasts 18 years or 50.

Tear-off of one existing layer, haul-away and dump fees, deck inspection and reasonable deck repair allowance, aluminum drip edge on all eaves and rakes, OC starter strip, an OC-brand synthetic underlayment, ice-and-water protection sized to the install tier, hip and ridge cap, ridge ventilation correction when measurement shows it is needed, the shingle, manufacturer warranty registration on your behalf, and the permit when the jurisdiction requires one. The JDH 5-year transferable workmanship warranty is on every install regardless of tier. The free PCC forensic inspection and Digital Analysis video are also included with no obligation to buy anything.

Above average, but not automatically unreasonable. A $25,000 Maryland asphalt install typically means one of: roof area over 30 squares, a complex hip-and-gable line with multiple dormers, decking that needs broad replacement, the upper Duration tier with the full Owens Corning Total Protection Roofing System accessory stack for Platinum Protection eligibility, or all of the above. Most JDH single-family asphalt installs land in the $11,500 to $16,500 range on a 20-square roof. Above $20,000, we will show you in writing where the extra dollars are going, line by line, and what could come out of the scope to bring it down.

Late fall (October through early December) and early spring (March through April) are the technical sweet spots for Maryland: temperatures cool enough for shingle handling without thermal cracking, warm enough for proper sealant cure. Summer installs work fine, but expect 1 to 2 day delays during 95F-plus heat. Winter installs are possible when the deck stays dry and ambient temperature stays above 40F; otherwise JDH schedules into the next warm window. The “winter is cheapest” line on most cost guides is only sometimes true in Maryland because winter installs need shingle pre-warming and longer cure windows that eat the discount.

For damage from a covered peril (wind, hail, fallen tree, fire, lightning, vandalism) most Maryland and Virginia policies cover replacement after your deductible. Age-related wear and tear is generally excluded. JDH documents claims with HAAG Master Certified impact measurements, Xactimate-formatted scopes of loss, and photo evidence carriers cannot dismiss. JDH does not act as a public adjuster; the coverage decision belongs to the carrier. Most JDH-documented claims settle in 9 to 21 days. See the claims walkthrough for what to do (and what NOT to say to the adjuster) when storm damage hits.

Short version: the price you see in a $5,500 roof ad is for the shingles and the labor to nail them on. What gets skipped to hit that price is the layered system underneath: ice-and-water shield, synthetic underlayment (replaced by 15-pound felt), deck repair allowance, new aluminum flashings, ventilation correction, OC-brand starter and hip-and-ridge cap, and any meaningful workmanship warranty. The shingle on the curb looks similar; the layers you do not see are what decide whether the roof lasts 12 years or earns the OC Platinum Protection warranty. JDH’s floor is higher because JDH prices a 30-year system, not a 12-year cosmetic. The full skipped-line list is in the section above this FAQ.

Most Maryland and Virginia single-family asphalt installs are a one-day job: crew arrives 7 to 8 AM, tear-off complete by lunch, new system installed by 5 to 6 PM, magnet sweep of the property and a walkthrough before sunset. Larger Bay-front colonials with hip roofs, steep gables, multiple dormers, or significant deck repair may need a second day. JDH schedules a specific day and an arrival window, not an all-day “sometime between 7 and 5” window.

Yes, through Service Finance Company. Promotional 0% APR options are available for qualified Maryland and Virginia homeowners; most homeowners land around 6.99% APR over 10 years, subject to credit approval. Approved financed jobs require no deposit; non-financed jobs require a one-third deposit at contract signing, which is the legal maximum in Maryland and Virginia. JDH walks the rate, term, and monthly payment options on-site so you can decide what fits your budget before you sign anything. See financing for current promotional windows.

Two things have to be true. First, the install has to be performed by an Owens Corning Platinum Preferred Contractor (JDH is one, #229690), which is the top 1% of OC’s contractor program nationally. Second, the install has to include the full Owens Corning Total Protection Roofing System: an OC underlayment, OC ice-and-water shield, OC starter strip, OC hip-and-ridge cap, OC ventilation, and the shingle. JDH registers the warranty on your behalf within two business days of completion. The 50-year coverage is non-prorated and transferable to the next homeowner one time, which is what a buyer’s home inspector asks about during resale.
