Know Before It's Too Late
Not Sure If You Need Service?
Most exterior failures don't announce themselves until the damage is already done. This guide shows you what to look for on your roof, siding, gutters, and windows, what each sign means, and what happens if you let it go.
Roofing
Your roof is the most consequential system on your home. Most failures are preventable if caught early. Here is what to look for from the ground, in your gutters, and in your attic.
Curling or Clawing Shingles
What it means
Shingles curl at the edges (cupping) or bow upward at the center (clawing) when they lose moisture and delaminate with age. Either pattern means the shingle is no longer lying flat and no longer sealing the course below it.
If you ignore it
Wind gets under lifted edges and strips shingles in the next storm. Exposed decking follows quickly. One storm event turns a repair into a full replacement.
Granules in Your Gutters
What it means
The mineral granules on shingles protect the asphalt layer from UV degradation. Finding heavy deposits in your gutters means the protective surface is wearing off.
If you ignore it
Bare asphalt deteriorates rapidly in sun and heat. Shingles crack and shrink within a few seasons of significant granule loss. The roof age clock accelerates once this starts.
Missing Shingles
What it means
Any area of exposed decking is an immediate leak risk. Missing shingles are often treated as a minor cosmetic issue, which is a mistake.
If you ignore it
Water enters and saturates the decking below. One missing shingle that sits through a rainy season can require replacing multiple sheets of decking on top of the shingle repair itself.
Soft Spots or Sagging
What it means
A visible sag in the roof line, or soft spots felt when walking the roof, mean the decking is compromised. This is almost always from long-term moisture intrusion that was never caught.
If you ignore it
Structural damage to rafters follows. What starts as a few waterlogged sheets of OSB becomes a partial structural failure if left. This is the most expensive outcome on this entire page.
Roof Age Over 20 Years
What it means
Most architectural shingles have a functional lifespan of 20 to 25 years in the Mid-Atlantic climate. An older roof may look fine from the ground and still be near the end of its reliable service life.
If you ignore it
Failure becomes unpredictable. Components fail at once rather than one at a time. Emergency replacements in winter cost more than a planned replacement in a good weather window, and the water damage between event and repair adds to the bill.
Rust or Separation at Flashing
What it means
Flashing seals the joints where the roof meets vertical surfaces: chimneys, plumbing vents, skylights, dormers. Rust or separation means the seal is broken at one of the highest-risk leak points on the roof.
If you ignore it
Water tracks down the inside of the wall cavity undetected. By the time you see a stain on a ceiling, there is often significant hidden damage behind the drywall you cannot see.
Siding
Siding does more than affect how your home looks. It is the moisture barrier between your exterior sheathing and the weather. When it fails, the damage migrates inward.
Warping or Buckling Panels
What it means
Panels that bow outward or have visible waves are losing their shape from moisture infiltration, improper installation, or material breakdown. Warped panels no longer lap correctly, which opens gaps.
If you ignore it
Moisture enters at the overlaps and wicks into the sheathing behind the panel. By the time you notice soft drywall or mold inside, the sheathing and sometimes framing members are already damaged.
Cracking, Splitting, or Gaps
What it means
Physical breaks in the siding surface are direct entry points for water and pests. Gaps at seams or corners where caulk has failed accomplish the same thing.
If you ignore it
Insects nest in the cavity behind failed panels. Water enters on every rain event. Both cause damage that does not show up until it is well established.
Soft or Spongy Sections
What it means
If a panel gives slightly when you press it, the panel itself or the sheathing directly behind it is rotting. Wood rot spreads. It does not stay where you find it.
If you ignore it
Rot works outward from the wet core. A section that feels slightly soft today can eat through the sheathing layer and into wall framing within one or two wet seasons.
Persistent Interior Moisture Stains
What it means
Staining or bubbling paint on interior walls near the exterior is often a siding failure before it is a roofing or window failure. The water is tracking in through the wall envelope.
If you ignore it
Mold establishes in wall cavities within days of sustained moisture. Remediation once mold is present is a separate, expensive job on top of whatever exterior repair caused it.
Fading Beyond Normal Weathering
What it means
Some fading is expected. Heavy chalking (a white powder residue that comes off when you wipe the surface) or severe, uneven color loss means the protective coating on the material is gone.
If you ignore it
Material without its protective coating weathers dramatically faster. Faded sections also absorb more heat, which accelerates warping and cracking.
Gutters
Gutters exist to move water off your roof and away from your foundation. When they stop doing that job, the damage they cause is disproportionate to how inexpensive they are to fix.
Gutters Pulling Away from Fascia
What it means
Gutters pull away when the fascia behind them softens from rot, or when the hanger hardware fails. Either way, the gutter is no longer directing water into the downspout.
If you ignore it
Water dumps directly behind the gutter onto the fascia and soffit, accelerating the rot that caused the separation. It also falls at the foundation rather than being carried away by the downspout.
Rust Stains on Siding or Trim
What it means
Orange or brown staining running vertically below the gutter line is the gutter rusting from the inside. The rust streak shows you exactly where water is escaping.
If you ignore it
A rusting gutter will eventually develop holes or seam failures. Once water is running behind the gutter consistently, fascia damage follows.
Visible Holes, Cracks, or Failed Seams
What it means
Sectional gutters fail at the seams. Older steel gutters rust through. Any opening in the gutter body means water exits somewhere other than the downspout.
If you ignore it
A small hole that drips on a foundation for a few years creates a wet zone that seeps into the basement or crawlspace. The gutter repair is cheap. The foundation waterproofing is not.
Sagging or Improper Slope
What it means
Gutters should slope toward the downspout at roughly a quarter inch per ten feet. A sagging section collects standing water, which adds weight, accelerates rust, and provides a breeding ground for mosquitoes.
If you ignore it
Standing water accelerates every form of gutter deterioration. The added weight eventually pulls hangers loose, which leads back to the fascia separation problem above.
Water Pooling at the Foundation
What it means
If you notice puddles or erosion directly below the roofline after rain, the downspouts are not moving water far enough away, or the gutters themselves are overflowing or leaking.
If you ignore it
Foundation moisture is one of the most expensive problems a homeowner can face. Wet basements, hydrostatic pressure on foundation walls, and crawlspace mold all trace back to gutters that are not doing their job.
Windows & Doors
Windows and doors are the most visible parts of your home's envelope. Seal failure and frame rot are the two most common problems, and both are usually hiding in plain sight.
Fog or Condensation Between Panes
What it means
Double and triple-pane windows have an inert gas seal between the panes. When that seal breaks, moisture gets in and fogs the glass. A fogged unit has lost its insulating value entirely.
If you ignore it
A failed IG unit does not get better. It continues to lose insulating value over time. You are paying to heat and cool air that is leaking directly through the window.
Drafts Around the Frame
What it means
Hold your hand near the frame on a cold day. Any cold air movement means the window is no longer air-sealed. This is usually a failed weatherstrip, a shrinking frame, or an installation that was never properly air-sealed to begin with.
If you ignore it
A single drafty window can add measurably to your heating and cooling bills. Multiple windows drafting means you are conditioning your home and the outdoors simultaneously.
Rot or Soft Wood in the Frame
What it means
Press a key or a screwdriver against the wood frame or sill. If it sinks in with light pressure, the wood has rot. This is common on older wood windows and on any frame where the exterior caulk has failed.
If you ignore it
Rot spreads. Frame rot works into the rough opening and then into the framing members. Replacing a window when only the window needs replacing is straightforward. Replacing it after the framing has rotted is a much larger project.
Difficulty Opening, Closing, or Latching
What it means
Sticking or binding windows and doors indicate frame warping, foundation settlement, or swelling from moisture intrusion. A door that does not latch flush is also a security concern.
If you ignore it
Frame movement from moisture tends to get worse, not better. Catching it early usually means a window or door replacement. Catching it late sometimes means a structural correction first.
Water Stains on the Interior Sill
What it means
Staining on the sill or paint bubbling at the bottom of the frame means water is getting past the exterior seal consistently. This is a flashing or caulk failure at minimum, and sometimes a failed sill pan.
If you ignore it
The water is going somewhere after it runs off the sill. It tracks into the wall cavity below the window. This is how mold establishes in areas you cannot see or reach.
