7 Signs Your Roof Needs Replacing

1. Age — the boring one that matters most

A standard asphalt shingle roof in Western New York gives you roughly 20 to 30 years. Architectural shingles sit at the upper end of that, three-tab at the lower. If you know your roof was done in the late 1990s, you are in the window regardless of how it looks from the driveway.

If you do not know the age, two shortcuts. Check whether the previous owner left paperwork, and look at your street. Subdivisions get built at the same time and re-roofed at the same time. If three neighbours have had dumpsters in the driveway in the last two summers, you are probably next.

2. Granules in the gutters

Asphalt shingles are protected by a layer of mineral granules. When those wash off, the asphalt underneath is exposed to UV and starts to break down fast. A handful of granules after a brand-new install is normal. A steady accumulation of coarse black grit in the gutters and at the bottom of the downspouts, year after year, means the shingles are shedding their armour.

From the ground, look for slopes that appear shinier or darker in patches than the rest of the roof. That is bare asphalt showing through — usually first on the south-facing side, which takes the most sun.

3. Curling, cupping or clawing

Look along the roof from an angle rather than straight on. Healthy shingles lie flat. As they age they curl at the edges (cupping) or lift in the middle (clawing). Once shingles are curled they no longer seal to each other, which means wind gets underneath and driving rain gets in.

A roof that looks fine from the street and terrible from a ladder is completely normal. That is exactly why estimates should be done in person and not off satellite imagery.

4. Missing shingles after a windy week

WNY gets real wind. One or two shingles off after a bad storm is a repair. But if you are losing shingles every time it blows hard, the sealant strips have failed across the whole roof and the rest of them are only still up there because they have not been tested yet.

5. Stains on the ceiling or walls

Brown rings on a bedroom ceiling, staining where a wall meets the ceiling, or bubbling paint near an exterior wall all mean water is getting in. It may be the roof, it may be flashing, it may be an ice dam, it may be a bathroom fan venting into the attic. Worth noting: the stain is rarely directly under the leak. Water travels along rafters before it drops.

6. What the attic tells you

This is the most useful ten minutes you can spend. On a bright day, go up with the lights off.

• Pinpricks of daylight through the roof deck — that is a hole.
• Dark water staining on the underside of the sheathing.
• Soft or spongy plywood, or plank decking that has split at the nails.
• Sagging between the rafters, visible as a wave in the roof deck.
• Damp or compressed insulation directly under a stained area.

7. Sagging, moss, and the things you can see from the yard

A visible dip or wave along the ridge or between rafters suggests the decking or the structure below it has been wet for a long time. That is not a wait-and-see item — get it looked at.

Moss and dark algae streaking are mostly cosmetic in the short term, and very common on shaded north-facing slopes in leafy neighbourhoods like Williamsville and North Buffalo. But moss holds moisture against the shingle surface, and over years that shortens the roof's life. If you are replacing anyway, algae-resistant shingles are worth the small upcharge under heavy tree cover.

Repair or replace? The honest test

The question we ask ourselves on every estimate is simple: is the problem localized or is it everywhere?

• Localized — a failed vent boot, a flashing detail at a chimney, storm damage on one slope, a few blown-off shingles on a roof that is otherwise in good condition. Repair it. We will say so.
• Everywhere — curling across multiple slopes, widespread granule loss, a roof past 25 years. A patch here buys you a season and you pay for the tear-off anyway.
• The awkward middle — a 15-year-old roof with one bad slope. Sometimes a partial replacement makes sense. Sometimes it just means two mismatched roofs. We will give you our actual opinion.

One thing we will not do is tell you that you need a full replacement when you do not. A repair customer who feels dealt with straight is how a company stays busy for thirty years on referrals.
