Is a new roof worth the cost?

Yes. A new architectural shingle roof typically recovers 60-70% of its cost at resale, prevents far more expensive water damage, and often lowers your homeowner's insurance premium — especially with impact-resistant shingles.

How long does a roof replacement take?

A typical Southern Maryland single-family home is a one- to two-day job for an experienced crew. Larger or more complex roofs can take three to four days.

Do I need to be home during the replacement?

No. Most homeowners go to work as usual. We do recommend moving cars out of the driveway and covering items in the attic.

Will insurance cover a full roof replacement?

Only if the damage is from a covered sudden event (wind, hail, fallen tree, fire). Age and wear are never covered. If you suspect storm damage, get an inspection before filing.

Can I install a new roof over the old one?

Maryland code allows up to two layers, but we almost never recommend it. A layover hides decking problems, voids most manufacturer warranties, and shortens the life of the new shingles.

How do I get an accurate quote?

An accurate quote requires an on-roof measurement, not a satellite estimate alone. Summit Exteriors offers free in-home estimates in Calvert, Charles, and St. Mary's counties with a same-day or next-day written quote.

How Much Does a New Roof Cost in Southern Maryland? (2026)

In 2026, most Southern Maryland homeowners pay between $9,500 and $18,000 for a full asphalt shingle roof replacement on a typical single-family home (roughly $4.75 to $7.50 per square foot installed). Premium architectural shingles, steep pitches, multiple stories, and metal or cedar upgrades push pricing higher — often $20,000 to $40,000+.

Average cost ranges in 2026

For a standard 1,800-2,400 sq ft single-family home in Calvert, Charles, or St. Mary's County, expect $9,500-$18,000 for a complete tear-off and replacement with architectural asphalt shingles. Smaller ranchers can come in around $8,000. Larger two-story homes, complex rooflines, or homes with steep pitches commonly land in the $18,000-$28,000 range. Premium materials (standing-seam metal, synthetic slate, cedar) typically run $25,000-$55,000+.

Cost per square (and per square foot)

Roofers price in 'squares' — one square equals 100 square feet. In Southern Maryland in 2026, a full architectural shingle replacement runs roughly $475-$750 per square installed, or $4.75-$7.50 per square foot of roof area. Note that roof area is larger than your home's footprint because of pitch and overhangs — a 2,000 sq ft home often has 2,400-3,000 sq ft of roof surface.

What drives the price up or down

Six things move the number the most: (1) Roof size and number of squares. (2) Pitch — anything over 8/12 requires roof jacks, harnesses, and slower work. (3) Number of stories — two- and three-story homes cost more in labor and staging. (4) Tear-off layers — removing two layers of old shingles adds disposal cost. (5) Decking replacement — rotted plywood is usually $70-$110 per sheet installed and not known until tear-off. (6) Material grade — 3-tab vs. architectural vs. designer or impact-resistant shingles.

What's included in a quality quote

A complete Southern Maryland roof replacement should include: full tear-off and disposal, new synthetic underlayment, ice and water shield at eaves and valleys, new drip edge, new pipe boots, new step and counter flashing where needed, ridge vent, architectural shingles, ridge cap shingles, and a workmanship warranty. If a quote is missing flashing, underlayment, or ventilation line items, the price isn't really comparable.

Material options and price differences

3-tab asphalt: cheapest upfront ($4.00-$5.00/sq ft) but only 15-20 year life — rarely worth it. Architectural asphalt: the Maryland standard, 25-30 year life, $4.75-$7.50/sq ft. Impact-resistant Class 4 shingles: $6.50-$9.00/sq ft and often qualify for a homeowner's insurance discount. Standing-seam metal: $12-$18/sq ft, 40-70 year life. Synthetic slate or cedar shake: $14-$22/sq ft.

Hidden costs to budget for

Plan a 5-10% contingency for decking replacement — the most common surprise. Skylights, chimney flashing rebuilds, satellite dish removal, solar panel detach-and-reset, and gutter replacement are common add-ons that aren't always in the base quote. Permit fees in Calvert, Charles, and St. Mary's counties are modest but should be itemized.

How to save money without cutting corners

Replace in the shoulder seasons (late fall or early spring) when crews have more availability. Bundle gutters or siding if they're also due — mobilization is a real cost. Don't downgrade underlayment or flashing to save a few hundred dollars; those are the components that decide whether the roof actually lasts. Get three quotes from licensed Maryland contractors (MHIC license required) and compare line items, not just totals.

Financing and insurance

Many Southern Maryland roofers offer 0% promotional financing through GreenSky or Service Finance for qualified buyers. If your roof was damaged by a covered storm event, homeowner's insurance may pay for the replacement minus your deductible — see our hail and storm guides for the claims process.
