This block is where United Developers inserts its own verified, current price ranges for this area: a per-square range by material tier, a per-sheet decking replacement rate, a typical tear-off and disposal figure, and a typical permit fee for this jurisdiction. Those numbers must come from your own recent signed jobs and current supplier and disposal pricing, and they should carry the date they were last verified.
Until then this page deliberately publishes no figures. A number invented for search traffic is worse than no number: it sets an expectation you then have to argue a homeowner out of on their own porch, and it is the reason so many roofing cost pages are useless. Everything below is what genuinely determines the price, which is the part you can act on.
What actually sets the price
Roof area, measured in squares
A roofing square is one hundred square feet of roof surface. It is not the same as your house's floor area, and it is not the footprint. A steeper roof covers more surface over the same footprint than a shallow one, and overhangs, porches, dormers and garage returns all add area. Any quote should state the number of squares it is based on. If it does not, you cannot compare it to anything.
Pitch and slope
A shallow roof can be walked. A steep one needs staging, roof jacks and fall protection, which means more setup time and slower work for the same area. Slope also determines what may legally and sensibly be installed: below a certain slope, shingles are the wrong product no matter what anyone tells you, and the roof needs a low-slope system instead. A quote that puts shingles on a nearly-flat roof is not a cheaper quote, it is a shorter roof.
Complexity: hips, valleys, dormers and penetrations
Two houses with identical square footage can be genuinely different jobs. Every hip and valley is cut waste and linear feet of flashing. Every dormer is four more transitions. Every chimney, skylight, vent and mechanical curb is a detail that has to be flashed rather than sealed. Complexity is the driver homeowners underestimate most and the one that separates two bids that look otherwise similar.
How many layers have to come off
A roof that has already been covered once or twice costs more to remove: more labour, more disposal weight, more time. Layer count is knowable before anyone quotes, and any contractor who has not checked is guessing on your behalf. Recovering over an existing roof rather than tearing off is cheaper today and it is the wrong answer when the existing system is saturated, when layers are already stacked up, or when nobody knows what the deck is doing.
Deck condition and the per-sheet replacement rate
You cannot know what the decking looks like until the old roof comes off. That is the honest position, and the correct way to handle it is not to guess — it is to name a per-sheet price for replacement in the proposal, so that if soft or delaminated sheathing turns up, you already know the cost and nobody is renegotiating with your roof open. A proposal with no decking line is a proposal with a hole in it.
Flashing: new metal, not reused metal
Step flashing woven into the courses, counter flashing at masonry, a kick-out at the bottom of every roof-to-wall run, and a cricket behind a wide chimney. Flashing is where the large majority of leaks we chase actually originate. Reusing old metal saves a small amount today and is the single most common reason a new roof leaks in year two. The proposal should say explicitly that flashing is new.
Underlayment and ice-and-water membrane
Synthetic underlayment across the field, and self-adhered ice-and-water membrane at the eaves, in the valleys, and around every penetration. How much coverage is specified is a real cost difference between bids and it is invisible once the roof is on, which is exactly why it is where corners get cut.
Ventilation, intake and exhaust
Exhaust at the ridge without matching intake at the soffit does close to nothing, and an under-vented assembly cooks the roof you just paid for from underneath. Adding or correcting ventilation is real work with a real cost, and it is one of the few line items that changes how long the roof lasts. Ask what the existing intake area is and what the plan is.
Material tier
Three-tab, architectural, premium and impact-resistant shingle, standing-seam metal, slate, and on low-slope roofs modified bitumen, single-ply membrane or built-up systems. The spread between the cheapest and the most expensive option is large. It is also the part of the decision most under your control, and the part contractors talk about most because it is the easiest to upsell. It is not the part that determines whether your roof leaks.
Disposal, measured by weight
Tear-off debris is charged by weight at the transfer station, and a multi-layer roof, a built-up asphalt roof or a slate roof is dramatically heavier than a single layer of shingle. Disposal should appear as its own line rather than disappearing into a lump sum.
Permits, inspections and review
Fees vary by jurisdiction, and in a historic district there may be a design review on top of the building permit that governs what material and profile you are allowed to use at all. Review timelines are frequently longer than the construction timeline. The proposal should say who is pulling the permit and whether the fee is included.
Access and staging
Where does the dumpster go, how does material get to the roof, and can a truck get close? A house with a driveway and a clear side yard is a cheaper job than an attached house on a narrow street with alley-only rear access and no place to legally park a container. On rowhouse work this is not a footnote, it is a meaningful share of the labour.
Warranty tier
There are two different warranties and they are frequently confused on purpose. The manufacturer's material warranty covers the product, and the better system warranties require a certified installer and the full set of system components, not just the shingle. The workmanship warranty is the contractor's own promise about the installation, and it is only worth what the contractor is worth. Get both in writing and read what voids them.
Arlington, VA specifics
The housing stock here
Small lots and older housing: 1920s through 1950s bungalows, Capes and colonials across Arlington's established neighbourhoods, plus a steady stream of tear-downs and large new builds, and dense townhome and condominium stock along the corridors.
Which drivers bite hardest in Arlington
Access and lot size are unusually large drivers in Arlington. Tight lots, short setbacks, on-street parking and mature trees limit where a dumpster goes and how a crew stages, which costs time. Roof areas tend to be smaller than in the outer suburbs, which cuts material but does not cut the fixed costs of mobilising, permitting and setting up, so the cost per square on a small roof is typically higher than people expect.
Permits and review
Arlington County issues and inspects residential building permits countywide — there are no incorporated towns to complicate it. Some neighbourhoods have local historic district designation which adds a design review step for exterior work. Confirm the current requirement for your address. The permitting authority is Arlington County's permit office. Requirements and fees change, so confirm the current position for your address rather than relying on what was true last year.
One more local factor
On the older stock, expect the layer question to matter. Many Arlington roofs have been covered at least once and full tear-off is usually the right call rather than a third layer.
How to read a roofing quote
A roofing proposal that cannot be compared to another roofing proposal is not doing its job. Here is what should be on the page, in writing, before you sign anything. If a bidder will not put these in writing, that is your answer.
- The number of squares the price is based on, and the pitch.
- Whether it is a full tear-off or a recover, and how many existing layers are assumed.
- A named per-sheet price for decking replacement, and who decides how much gets replaced.
- Underlayment type, and exactly where ice-and-water membrane is being installed.
- That flashing is new — step, counter, chimney and kick-out — and not reused.
- New pipe boots on every plumbing penetration.
- The ventilation plan: what intake exists, what exhaust is being installed, and the balance between them.
- Drip edge and perimeter edge metal, specified rather than assumed.
- Skylights: replaced, re-flashed, or left alone, stated explicitly.
- Gutter and downspout work, if any, separated out.
- Disposal and dumpster, as their own line.
- The permit: who pulls it, and whether the fee is in the price.
- Both warranties, in writing, with their exclusions.
- The payment schedule, and what triggers each payment.
- Proof of licence and current insurance, with numbers you can verify yourself.
Red flags
- A price over the phone. Nobody can price a roof they have not measured. A phone number is a range designed to get an appointment, and it will move.
- An offer to cover your deductible. This is not a discount. It is a misrepresentation to your insurer and you are the one whose name is on the policy.
- A large deposit before material is on site. Ask what it is for and what it buys.
- Today-only pricing. A roof is not a perishable good. Urgency in the sales process is about the contractor's cash flow, not your roof.
- A lump sum with no line items. If it cannot be itemised it cannot be compared, and that is usually the point.
- Being asked to pull your own permit. That is a statement about their licensing.
- No named per-sheet decking rate. Guarantees a conversation about money once the roof is open and you have no leverage.
- Reused flashing described as 'we'll reseal it'. Sealant is not flashing.
- No physical address or verifiable licence number on the proposal.
Questions worth asking every bidder
- How many squares is this roof, and how did you measure it? The answer should be specific and the method should be either a physical measurement or a verifiable aerial measurement.
- How many layers are up there now, and are you tearing off or recovering?
- What do you charge per sheet for decking replacement, and who decides how much gets replaced?
- Is all the flashing new? Say the word flashing and see whether the answer is specific or vague.
- What is my current intake ventilation, and what is your plan for it?
- Who pulls the permit and is the fee in this number?
- What exactly voids each of the two warranties?
- Is the crew employed by you or subcontracted, and who is on site supervising?

Arlington, VA roof cost questions
Why does this page not just give me a price for Arlington, VA?
Because a number published for search traffic is not a quote, and pretending otherwise wastes your time. Roof cost is set by measurable things — squares, pitch, complexity, layer count, deck condition, material tier, disposal weight, permits and access — that vary enormously between two houses on the same street. What this page gives you instead is the complete list of what moves the number and exactly what to demand in writing, which is the part that actually protects you when the bids come in.
How many quotes should I get?
Three is the usual advice and it is reasonable, but the number matters less than whether they are comparable. Three lump sums for three different scopes tell you nothing. Three line-item proposals that all state squares, layers, decking rate, underlayment coverage, flashing and ventilation can actually be compared.
Is the cheapest bid always a bad idea?
Not always, but you should be able to explain why it is cheaper. Sometimes it is a leaner overhead structure, which is fine. More often it is a recover instead of a tear-off, reused flashing, thinner underlayment coverage, no ventilation work, or a decking allowance that turns into a change order. If you cannot identify the reason, assume the difference is in something you will not see until it leaks.
Who issues the permit in Arlington, VA?
Arlington County issues and inspects residential building permits countywide — there are no incorporated towns to complicate it. Some neighbourhoods have local historic district designation which adds a design review step for exterior work. Confirm the current requirement for your address.
Does insurance change the cost conversation?
It changes who pays, not what the work is. If the roof is failing from age and wear, that is generally a maintenance expense rather than a claim. If a covered peril caused the damage, your carrier decides coverage under your policy. Either way, the scope of work should be the same scope, and we are contractors rather than public adjusters.
