Most Brooklyn homeowners wait too long to replace their roof. Here are 7 warning signs that need attention now.
Standard asphalt shingles last 20 to 25 years. If your roof is approaching or past that age, get a professional inspection even if it looks fine from the street.
Shingles that are curling at the edges, cracking, or simply missing leave your roof deck exposed to water and weather damage. Even a few missing shingles can lead to a major leak.
Check your gutters after rain. If you see dark, sand like granules collecting there, your shingles are deteriorating. This is one of the earliest and most reliable signs of an aging roof.
Brown stains on your ceiling or walls usually mean water is getting through. Even small leaks can lead to mold, damaged insulation, and structural rot if ignored.
A failing roof loses its insulating properties. If your heating or cooling bills have gone up without explanation, your roof may be letting conditioned air escape.
A sagging roof is a serious structural warning. This can indicate rotted boards or a weakened foundation. Do not wait on this one. Call a contractor immediately.
If you can see daylight through your attic boards, water and cold air can get in too. Check your attic with a flashlight, especially after heavy rain or wind.

One failure point on an otherwise sound roof is a repair. Several failures in separate areas on a roof past its expected life is a replacement. Here is how the decision actually goes on a Brooklyn house.
| What you are seeing | Repair | Replace |
|---|---|---|
| One leak, roof under 15 years | Yes, trace the source and fix the detail | No |
| Leaks in two or more separate areas | Rarely worth it | Usually yes |
| Granule loss in gutters, roof over 18 years | No, the mat is exposed | Yes, start planning |
| Soft or spongy deck underfoot | No, structure is involved | Yes |
| Curling or cupping tabs across a slope | No, that is age not damage | Yes |
| Flashing failure only, field in good shape | Yes, this is the common case | No |
| Third repair in two years | You are paying twice | Yes |
You do not need to climb anything to get most of the answer. Look in the gutters after a heavy rain: a layer of dark granules like coarse sand means the shingle mat is being exposed and the clock is running. Go into the attic with a flashlight on a bright day and look up. Pinholes of daylight mean openings. Dark staining on the sheathing means water has been there. Soft or compressed insulation in a band usually marks where it comes in.
From the street, look along the roof line rather than at it. A straight ridge that now dips, or a slope that reads wavy rather than flat, points at the deck rather than the covering, and deck problems do not get better.
We get asked constantly whether twenty years means a roof is finished. It does not by itself. A twenty year old architectural shingle roof with sound flashing, good attic ventilation and no leak history can easily have five years left. A fifteen year old roof with three failed penetrations and no ventilation is done. Condition plus age is a good predictor. Age alone sells roofs that did not need selling.
The number people underestimate is not the roof, it is everything under it. Once water has been getting in for a season you are typically adding deck replacement at $95 to $180 a sheet, insulation that has to come out, and interior repair. A $12,000 roof becomes an $18,000 project with ceilings and paint on top. On an attached Brooklyn house it can become your neighbor's problem too, which is a conversation nobody enjoys having.
If you recognized two or more of the signs above, get it looked at before the next freeze rather than after it. We inspect free, go in the attic where there is access, photograph what we find, and tell you plainly whether you are in a repair conversation or a replacement one. Half of those visits end with us saying the roof is fine. See our roof inspection page for what the check covers, or roof replacement for cost and timeline.
One failure point on an otherwise sound roof is a repair. Failures in two or more separate areas, a deck that feels soft underfoot, curling across a whole slope, or a third repair in two years all point to replacement. The single most useful test is whether the problems are isolated or spread, not how old the roof is.
They are the protective surface coming off the shingle, which exposes the asphalt mat underneath to UV. A few after a new install is normal. A dark sandy layer in the gutters on a roof over fifteen years old means the shingles are in their final stage and you should be planning rather than reacting.
Most of it, yes. Check the gutters for granules after heavy rain. Go in the attic with a flashlight on a bright day and look for pinholes of daylight, dark staining on the sheathing, and damp or compressed insulation. From the street, sight along the ridge for dips and look for a slope that reads wavy rather than flat.
No. A twenty year old architectural shingle roof with sound flashing, good ventilation and no leak history can have years left. A fifteen year old roof with several failed penetrations and poor ventilation is finished. Age alone is a weak predictor and it is the argument used to sell roofs that did not need selling.
If the roof is not leaking, usually nothing, and we will tell you to wait. If it is leaking, a winter of water adds deck replacement at $95 to $180 per sheet, insulation removal and interior repair. That typically turns a $12,000 roof into an $18,000 project, and on an attached house it can reach your neighbor as well.
