Signs You Need a New Roof The visible indicators a HAAG Certified inspector looks for, with severity tiers so you know which ones can wait and which can’t.

Most DMV roofs do not announce that they need replacement. The shingles do not fall off all at once. The leak does not appear before the damage. The decisions happen in stages: watch, schedule a HAAG inspection soon, replace now. These are the twelve signs, ranked by severity, that an Owens Corning Platinum Preferred contractor with 25+ years on DMV roofs would look for first.

Quick answer

The clearest signs a DMV roof needs replacement are widespread shingle curling and cupping, granule loss filling gutters, multiple bald or shiny shingle patches, three or more existing patch repairs on the same slope, and shingle age beyond 22 years. Single missing shingles, isolated leaks, and cracked pipe boots are almost always repair jobs, not replacement triggers. A HAAG Certified inspection is the only reliable way to know which side of the line your roof sits on.

Claude’s two-out-of-five rule

One sign on this list rarely means “replace.” Two or more on the same roof usually does. If you’ve got curling on one slope and granules in the gutter, that’s a system in decline — not a one-off repair. The combination matters more than any single symptom.

12 Signs Your Roof Needs Replacement

The signs below are organized by severity. WATCH means the indicator is present but does not yet require action. SCHEDULE means a HAAG Certified inspection should happen this month. REPLACE NOW means the conversation is no longer about repair.

01
REPLACE NOW

Widespread Curling, Cupping, or Buckling

Asphalt shingle edges that lift, curl upward, or buckle in the middle indicate the asphalt mat has lost its flexibility. This usually happens at 18+ years on architectural shingle and 12+ years on three-tab. When curling appears on multiple slopes, the system is at end of life regardless of remaining warranty years on paper.

What to doSchedule a HAAG Certified inspection. If curling is on more than one slope and other indicators are present, replacement is the right call.
02
REPLACE NOW

Multiple Bald or Shiny Shingle Patches

Granules are the UV-protection layer on asphalt shingle. When they are gone, the asphalt mat degrades within 12 to 24 months. Bald or shiny patches across multiple shingles mean the protection layer has failed. Patch repair is not viable at this stage.

What to doVisible from the ground from second-story windows or with binoculars. If bald patches are scattered across slopes, replace.
03
REPLACE NOW

Granule Loss Filling Gutters

A handful of granules is normal during the first 12 months after install. Cup-fuls during regular gutter cleaning, on an established roof, indicate end-of-life shingle wear. The pattern correlates directly with remaining lifespan: the more granules in the gutter, the closer to total failure.

What to doCheck during seasonal gutter cleaning. Cup-fuls plus visible roof bald patches = replacement.
04
REPLACE NOW

Three or More Existing Patches on the Same Slope

Targeted repair is the right call for one or two failures on an otherwise sound slope. When three or more patches already exist on the same slope, the system is hunting failures faster than they can be fixed individually. Continued patching becomes a false economy.

What to doCount visible patches on each slope. Three or more on a single slope means the slope itself needs replacement.
05
REPLACE NOW

Sagging or Visible Deck Damage from Inside the Attic

From inside the attic, look up at the underside of the deck. Visible daylight between deck seams, sagging between rafters, or active water trails on the underside of the OSB or plywood indicate structural-level damage. This is no longer a shingle problem.

What to doStop using the roof to hang heavy items. Schedule a HAAG Certified inspection within the week. Replacement scope likely includes substrate repair.
06
SCHEDULE INSPECTION

Shingle Age Beyond 22 Years

Architectural asphalt shingle in the DMV typically lasts 22 to 28 years. Three-tab shingle lasts 15 to 20 years. If you know your roof is older than these windows and you haven’t had a HAAG inspection in the last 2 years, the inspection is now overdue. See our companion article on how long does a roof last for the full lifespan breakdown.

What to doPull permit records or seller disclosure. Schedule a HAAG inspection if age exceeds the material’s normal lifespan.
07
SCHEDULE INSPECTION

Multiple Interior Ceiling Stains

A single stain on a single ceiling is often a localized leak that targeted repair will solve. Multiple stains across different ceilings, or recurring stains that come back after repair, indicate the system has multiple failure points. The leak path is no longer one boot or one valley.

What to doDocument the stains with photos (date stamp matters). HAAG Certified inspection with thermal imaging will trace the leak paths.
08
SCHEDULE INSPECTION

Storm Event in the Last 12 Months

Any DMV property within a documented wind, hail, or microburst event zone in the last 12 months should be inspected. Hail bruising does not show as a leak immediately. Wind uplift breaks sealant bonds without removing the shingle. Both produce documented insurance claims years after the original event.

What to doCheck NWS Sterling event records. If your ZIP was hit, schedule a HAAG Certified inspection. See storm damage roof repair for the full process.
09
SCHEDULE INSPECTION

Neighbors on the Same Block Have Already Replaced

DMV subdivisions were typically roofed in waves during initial construction. The original roofs on a 1995-built subdivision are all hitting end of life around the same year. If three or more houses on your block have already replaced, yours is likely close. The pattern is especially strong in Burke, Springfield, Centreville, Columbia, Bowie, and other mid-1990s-built communities.

What to doAsk neighbors when they replaced. If the pattern matches your build year, schedule an inspection now.
10
WATCH

Cracked or Damaged Pipe Boots and Flashing

Pipe boots crack at 8 to 12 years on most DMV roofs. Flashing fails at chimney transitions, dormer step joints, and wall-roof intersections. These are typically repair jobs, not replacement triggers, on an otherwise sound roof.

What to doSchedule a targeted repair. Replacement is only the right call if other end-of-life indicators are also present.
11
WATCH

Moss or Algae Growth on the North-Facing Slope

The shaded north-facing slope of a canopy-heavy DMV property often shows moss and algae years before the south slope shows any age. By itself, this is not an end-of-life indicator. Combined with curling, bald patches, or 22+ year shingle age, it is.

What to doTrim back the canopy where possible. Algae-resistant shingle treatments can extend life. Replace only when paired with other signs.
12
WATCH

Higher Heating and Cooling Bills

Roof systems work as part of the building envelope. A degraded attic ventilation system, missing or compressed attic insulation, or a roof deck that has lost its thermal performance can show up as higher energy bills before it shows up as visible damage.

What to doPair roof inspection with an attic insulation evaluation. Energy-bill indicators alone do not justify replacement; combined with shingle-age signs, they tip the conversation.

“Many inspections are designed primarily to generate estimates quickly, not to fully diagnose building envelope issues. A drone or thermal camera alone doesn’t make someone an expert any more than buying golf clubs makes someone a professional golfer. When we leave a home, the homeowner should understand more about their roof than they ever did before we arrived.”

What our HAAG Certified inspector adds to this list

Kevin Butler is the HAAG-Certified roof inspector on our team. He inspects roofs in Burke, Springfield, Annandale, Fairfax, and across Northern Virginia every week. The twelve signs above are the visible indicators. Kevin is quick to point out that the most important indicator is the one most homeowners cannot see at all.

“Many inspectors never actually inspect the roof thoroughly. They make recommendations based on what they can see from the ground. Half of the roof is actually in the attic. The attic reveals previous leaks, ventilation problems, moisture, and signs of deterioration that the shingle surface will not always show. We use Problem, Cause, Consequence on every inspection. Identify the problem. Determine the cause. Evaluate what happens if it is left unaddressed.”

Kevin Butler, HAAG Certified Roof Inspector, DreamHome RemodelingGeorge Mason University · 20+ years inspecting Northern Virginia roofs

That is the difference between a list of warning signs and an actual diagnosis. Kevin uses thermal imaging to read attic temperatures and ventilation performance, moisture meters to detect water penetration that has not yet reached the ceiling, shingle gauges to measure wear, and endoscope cameras to look behind chimney flashing where the failure usually starts. The point is to walk away with data, not opinions, and to tell the homeowner the truth about what the roof actually has left.

Kevin frames the job the same way every time: “My responsibility is not to get every claim approved. My responsibility is to help homeowners make informed decisions based on accurate information. We are not in the business of replacing roofs prematurely. We are in the business of helping homeowners understand the true condition of their roof.”

From Kevin Butler, General Manager, HAAG Certified Inspector

“Roofing systems, ventilation systems, insulation, airflow, flashing, siding transitions, and moisture migration all interact together.”

From Lenny Scarola, President, DreamHome Remodeling

“I have always enjoyed lifting weights, and I can remember years ago carrying roofing bundles that were noticeably heavier than they are today.”

Frequently Asked Questions

How can I tell if I need a new roof or just a repair?
Repair is the right call when the issues are localized: a single missing shingle, a cracked pipe boot, an isolated flashing failure, or a damaged ridge vent on an otherwise sound roof. Replacement is the right call when widespread curling, multiple bald patches, granule loss filling gutters, three or more existing patches on the same slope, shingle age beyond 22 years, or substrate damage are present. A HAAG Certified inspection determines which bucket your roof falls into.
What is the most overlooked sign that a roof needs replacement?
Granule loss in gutters. Most DMV homeowners notice the granules during seasonal cleaning but interpret them as normal wear. A handful of granules is normal in the first 12 months after install. Cup-fuls on an established roof indicate end-of-life shingle wear. The pattern correlates directly with remaining lifespan.
Can I tell I need a new roof from the ground?
Several indicators are visible from the ground or from a second-story window: curling and cupping at shingle edges, bald or shiny patches, dark streaks (algae), sagging rooflines, and missing shingles. Other indicators require a closer look: granule loss in gutters, daylight in the attic, soft deck spots, and flashing failures. A HAAG Certified inspection confirms what you can see from the ground and identifies what you cannot.
How urgent is a sagging roofline?
A visibly sagging roofline indicates structural-level damage. The substrate sheathing (OSB or plywood) or the rafters themselves have lost integrity. This is no longer a shingle conversation. Schedule a HAAG Certified inspection within the week. Do not delay through another storm season. Replacement scope will include substrate or structural repair in addition to the shingle system.
If my neighbors are replacing their roofs, do I need to as well?
Not automatically, but the timing pattern is meaningful. DMV subdivisions were typically roofed in waves during initial construction. If three or more houses on your block have already replaced and your home is from the same build year, your roof is likely within a few years of end of life. Schedule a HAAG inspection to confirm where your specific roof sits in its lifespan.
How much does a new roof cost in Virginia or Maryland?
The average cost of an asphalt architectural shingle roof replacement in Virginia and Maryland is $13,500 to $32,000 for a single-family home with the Owens Corning Total Protection System as of 2026. Townhomes run $8,500 to $13,500. Estate homes with complex roof lines run $38,000 to $85,000. See roof replacement cost for the full DMV pricing breakdown.

Find Out Whether Your Roof Actually Needs Replacement

We climb the roof, walk the attic, and give you a written report. No “today only” pricing. No manager call. We will tell you whether your roof needs a repair, a partial scope, or a full replacement, with photos showing exactly why.

Local detail that actually matters

Roofing Codes and Permits in Virginia and Maryland

  • Roofing in Virginia is governed by the Virginia Residential Code, the residential part of the Virginia Uniform Statewide Building Code (USBC), which adopts the International Residential Code. In Maryland the equivalent is the Maryland Building Performance Standards.
  • Two details building officials look for on a DMV reroof: a metal drip edge at the eaves and rakes, and an ice-and-water barrier at the eaves to guard against ice-dam backup during our freeze-thaw winters.
  • Asphalt shingles must be rated for the local design wind speed, which across Fairfax County and Prince William County runs around a 90 mph basic wind speed.
  • Full roof replacement generally requires a building permit in Fairfax, Prince William, and Loudoun counties and most Maryland counties, while minor like-for-like repairs often do not. DreamHome confirms the permit requirement with your local building official before work starts.

Neighborhoods We Work In

DreamHome crews are on roofs and walls across Northern Virginia every week, including Woodbridge, Lorton, Springfield, Burke, and across the bridge in Maryland communities such as Waldorf, Bowie. We live in these communities, we know the housing stock, and we know which county building official issues the permit.

That local footprint is not a marketing line. It is why we already know the HOA architectural rules in places like Burke Centre, Reston, and Columbia, and the inspection quirks county to county.

The Honest Standard
