How Long Should a Roof Last?
Roofs aren’t meant to last forever, but their lifespan depends on the material. Here’s a general idea of how long different types typically last:
- Asphalt shingles: 15–30 years (most common in the U.S.)
- Metal roofing: 40–70 years
- Wood shakes or shingles: 20–40 years
- Clay or concrete tiles: 50+ years
- Slate roofing: 75–100+ years
If your roof is nearing the end of its expected lifespan, it might be time to start planning for a replacement—even if you don’t see obvious damage.
Signs It’s Time to Replace Your Roof
Not sure if your roof is in bad shape? Here are some signs it might be time for a full replacement:
- Shingles are curling, cracking, or missing – If a few shingles are loose, a repair might be enough. But if there are large sections with damage, it’s a bigger issue.
- Granules in your gutters – Asphalt shingles shed granules over time. If you see a lot of them washing into your gutters, your roof is wearing down.
- Leaks or water stains inside – If you notice water spots on ceilings or walls, your roof may not be keeping moisture out.
- Moss, mold, or algae growth – While some moss isn’t an emergency, excessive growth can trap moisture and cause long-term damage.
- Sagging areas – A drooping or uneven roof could mean structural problems underneath. This is a serious issue that needs immediate attention.
Catching these signs early can save you money. If your roof is showing multiple issues, Roof Replacement Lancaster PA or elsewhere applicable is often a better investment than frequent repairs.

- Inspection & Estimate
A professional roofer will inspect your roof and provide an estimate. They’ll check for damage, measure the area, and discuss material options. - Choosing Materials
Asphalt shingles are the most popular choice due to affordability, but if you want something longer-lasting, you might consider metal, tile, or slate. - Scheduling & Preparation

How Much Does Roof Replacement Cost?
The cost of a new roof varies based on the size of your home, material choices, and labor rates in your area. On average, homeowners pay anywhere from $5,000 to $15,000 for a full roof replacement.
