What would you like priced?
We measured your roof from the imagery. The same outline gives us your eave run and wall area, so we can put a range on the exterior trades too.
Six things that move the number
Every one of these changes what the job really costs. We would rather ask than quietly assume — your answers go straight to the specialist who inspects it.
Pitch changes real surface area by up to 40%. Guess it and we widen the range to be honest about that.
Sets staging and, for siding or paint, your wall area.
Decides whether a repair is honest or a replacement is the real answer.
Every extra layer is another full tear-off and another dumpster.
If the crew has to hand-carry, that is real labour and we price it.
If it qualifies, an insurance claim can change what you pay entirely.
Three ways to do this roof
Same measurement, three systems. Pick one and the range below updates.
ESTIMATED RANGE — NOT A FIRM PRICE
—
Estimate only. Your final price is set in writing after a free on-site inspection.
Read this before you compare it to anything. This is an estimate expressed as a range, built from satellite measurement and the answers above — not a firm price, not a contract, and not a bid. Roof decking, ventilation, flashing condition and the number of layers can only be confirmed on the roof. A United Developers specialist inspects the property at no cost and gives you a written, fixed price before any work is scheduled. We serve Maryland and Virginia.

Storm damage? If your roof qualifies for an insurance claim, your out-of-pocket is often just your deductible — we document it and support your claim with full documentation. Coverage decisions are always your insurer's to make.

A specialist verifies the measurement on-site and produces your exact price — free. On an approved storm claim, your deductible is typically your out-of-pocket cost.

Instant estimate

A real price range on the spot, using current Maryland pricing. A free on-site inspection locks the exact number.

Why our estimate is one you can trust

We've measured and replaced 650+ roofs across Maryland since 2005. The number you see is built on real local pricing and real experience — not a guess.

Measured, not guessed

Your estimate comes from the true traced area of your roof on live satellite imagery, adjusted for pitch — the same method our estimators use on-site.

Real local pricing

Ranges reflect current DMV material & labor costs for GAF architectural and metal systems — what you'd actually pay here, today.

Insurance-savvy

If a storm hit, we document the damage with a 20+ photo report and meet your adjuster on site. Coverage decisions are always your insurer’s to make. We work directly with your insurer, and meet your adjuster on-site.

*Every figure on this page is an ESTIMATE shown as a RANGE, never a firm price, offer or bid. Architectural shingle starts at $600–$800 per roofing square ($6.00–$8.00/sq ft) installed before adders; steep pitch, cut-up roofs, difficult access, extra shingle layers and local labour rates move it up, and the range is built line by line from the same retail price book our estimators quote from. Siding, gutters, windows, decks and exterior painting are priced the same way off the traced outline. Home additions and interior remodels are deliberately NOT priced online — those are scoped on site. Measurement from traced satellite imagery is preliminary; your final price is set in writing after a free on-site inspection, and nothing here obligates you to anything.
