How Much Does a New Roof Cost in Maryland in 2026?
A typical asphalt shingle roof replacement in Frederick, MD runs $8,000 to $18,000 depending on size, pitch and removal. Here is what drives the price.
A new asphalt shingle roof in Maryland typically costs $8,000 to $18,000 in 2026, with most Frederick County homes landing near $12,000 to $14,000 for a mid-range architectural shingle replacement. Flat roofs done in TPO membrane cost more per square foot. Your final number comes down to roof size, pitch, how many old layers have to come off, and what kind of shape the wood deck underneath is in.
We see it all the time. Two roofers walk the same house and one comes back with $9,000, the other with $16,000. The homeowner is stuck wondering who is being straight and who is padding the bill. Here is the thing: a real estimate comes down to a few things you can actually measure. Learn those, and you will read any quote with a clear head and catch the ones that are way off in either direction.
The national numbers back up that wide range. The Remodeling 2024 Cost vs. Value Report puts an average asphalt shingle replacement at roughly $30,000 nationally for a large home, while HomeAdvisor and Angi cost data show most homeowners paying between $5,900 and $13,000 for a standard re-roof. The spread is real, and most of it comes down to the four factors below.
How Much Does a New Roof Cost by Size?
Roofers measure roof size in squares. One square is 100 square feet of roof area, not floor area. A 2,000 square foot ranch with a simple gable has about 24 squares up top. Take a 2,000 square foot colonial with dormers and a steep pitch and you can be looking at 30 squares or more on the same footprint.
Here is how installed cost climbs with roof size for a standard architectural asphalt shingle job in Frederick County. These numbers assume one layer to tear off and a pitch you can walk.
| Roof size | Roof area | Low | Typical | High |
|---|---|---|---|---|
| 15 squares | 1,500 sq ft | $8,700 | $10,500 | $12,400 |
| 20 squares | 2,000 sq ft | $11,600 | $14,000 | $16,500 |
| 25 squares | 2,500 sq ft | $14,500 | $17,500 | $20,600 |
| 30 squares | 3,000 sq ft | $17,400 | $21,000 | $24,800 |
| 40 squares | 4,000 sq ft | $23,200 | $28,000 | $33,000 |
A 2,000 square foot ranch in Walkersville sits at the low end of these bands. A bigger colonial in Urbana or Mount Airy with several gables and a steep pitch can land in the high column even at the same square footage, because both the roof area and the labor go up.
How Much Does a New Roof Cost per Square Foot by Material?
What you put on the roof is the second big lever. EZ Home Services installs two systems for Maryland homes: asphalt shingles for pitched roofs and TPO single-ply membrane for flat or low-slope roofs. Here is what each runs per square foot, fully installed.
| Material | Per square foot (installed) | Best for | Expected lifespan |
|---|---|---|---|
| Asphalt 3-tab shingle | $4.50 to $5.50 | Tight budgets, rentals | 15 to 18 years |
| Architectural asphalt shingle | $5.80 to $6.20 | Most Maryland homes | 18 to 25 years |
| TPO membrane | $9.80 to $10.20 | Flat and low-slope roofs | 20 to 30 years |
Architectural shingles go on most of the homes we touch in Frederick, Urbana, and Mount Airy. They cost a bit more than basic 3-tab, but they carry longer warranties, hold up better in wind, and look a lot sharper on a colonial or craftsman. TPO is the right call for flat porch roofs, additions, and modern low-slope designs. You pay more per foot for the heat-welded seams and the longer service life, and on a flat roof it is worth it.
According to the National Roofing Contractors Association (NRCA), asphalt shingle roofs typically last 15 to 30 years depending on shingle grade and attic ventilation. Maryland’s freeze and thaw cycles tend to push roofs toward the low end of that range, which is a big reason we tell people a good architectural shingle is worth the small bump over 3-tab.
What Drives Your Roof Price: A Step-by-Step Breakdown
When we measure a roof in Frederick County, the quote gets built in this order. Walk through these five steps and almost every dollar on your estimate will make sense.
- Measure the squares. We measure the actual roof area, not floor area, and add for waste on hips and valleys. That sets the baseline for material and labor.
- Factor in pitch. Anything you can walk, up to about a 6/12 pitch, is standard labor. At 8/12 the crew needs toe boards and the labor rate goes up roughly 15 percent. At 10/12 and steeper, we price in roof jacks and harness setup, and labor can nearly double. Frederick and Urbana are full of steep colonial roofs that push quotes higher than folks expect.
- Count the layers to tear off. Maryland code allows two layers of shingles on a single deck, max. Most places, Frederick County and Montgomery County included, make you do a full tear off before a third layer goes on. Tear off adds $1 to $2 per square foot, and dumpster fees in the Baltimore Washington corridor run $450 to $800 a load.
- Inspect the decking. Nobody knows what the plywood underneath looks like until the old shingles come off. Budget $70 to $110 per 4 by 8 sheet of replacement plywood or OSB. Most jobs need 2 to 6 sheets, and bad rot can tack $1,500 to $3,000 onto the final invoice.
- Add accessories and permits. Underlayment, ice and water shield, drip edge, ridge vent, flashing, and the county permit round out the number. These are the lines cheap quotes quietly leave off.
Tear Off, Decking, and the Hidden Costs
If the roof already has two layers, plan on the high end of every range above. Double tear off is heavy, slow work. A good contractor writes decking repair into the estimate as an open allowance with a per sheet rate. Be careful with any quote that promises zero decking cost. That number usually gets walked back mid-job, right after the old shingles come off and the rot shows up.
Rotten decking from old leaks is common on roofs past 20 years old, especially around chimneys and valleys where the flashing gives out first. The Insurance Information Institute notes that water damage is one of the most common and costly home insurance claims, and a tired roof is where most of it starts. Swapping out soft decking during a re-roof costs a lot less than chasing a ceiling leak two winters down the road.
Permits and Code in Maryland Counties
Most Maryland counties make you pull a permit to replace a roof. Frederick County permit fees run about $120 to $180 for a typical single family home. Montgomery County is $150 to $250, and Howard County is in the same neighborhood. The contractor usually pulls the permit and passes the cost through.
Hire someone who skips the permit and you are the one holding the bag when you go to sell and the buyer’s inspector flags it. Northern Virginia counties play by their own rules, so homes in Loudoun and Fairfax usually need a permit and a final inspection too. A licensed roofer takes care of all this and leaves a paper trail that protects your sale down the line.
Sample Cost Breakdown: 2,000 sq ft Home in Frederick
Here is what a real mid-range architectural asphalt shingle estimate looks like for a 24 square home at 6/12 pitch with one layer to tear off.
| Line item | Cost |
|---|---|
| Tear off and disposal (1 layer, 24 sq) | $2,400 |
| Architectural shingles (Owens Corning Duration) | $4,800 |
| Synthetic underlayment | $650 |
| Ice and water shield at eaves and valleys | $550 |
| Drip edge, ridge vent, starter strip | $700 |
| Flashing (step and chimney) | $450 |
| Labor | $3,200 |
| Permit | $150 |
| Decking allowance (4 sheets) | $360 |
| Total | $13,260 |
That is a fair, middle of the road number for a straightforward Frederick County home in 2026. Quotes under $9,000 for the same scope usually skip the ice and water shield or drop down to 3-tab. Quotes over $17,000 for that same scope are either packing in premium materials or have a big sales team to feed. Want a number built for your actual roof?

How to Finance a New Roof in Maryland
Most people do not pay cash for a roof. In 2026, the financing options usually look like this.
- HELOC: 7.5 to 9 percent, the best rate for most homeowners who have equity
- Home improvement personal loan: 9 to 14 percent
- Contractor financing: 0 percent promotional for 12 to 18 months, then 14 to 20 percent
- Cash back credit cards on the deposit only, paid off before interest hits
A $13,000 roof financed on a HELOC at 8 percent over 10 years comes out to about $158 a month. In the first few summers, that is often less than what you save on energy with a properly ventilated new roof. We lay out the full set of options on our financing page so you can compare monthly payments before you sign anything.
Is a New Roof Worth It in Maryland?
A roof replacement is one of the better returns you can get on a home improvement. The Remodeling Cost vs. Value Report keeps ranking asphalt shingle roof replacement among the projects that recover the most at resale, usually returning more than half its cost in added home value, and metal and other upgrades can do even better in the right market. Now add the insurance angle, since plenty of carriers offer better terms on a roof under 10 years old, and a new roof pays you back three ways at once: resale value, lower premiums, and lower energy bills.
