Average Roof Longevity
Manufacturers offer estimates for an average roof life, depending upon the types of roofing materials:
- Asphalt shingles: 20-30 years
- Wood shingles: 30-40 years
- Laminate shingles: 24-30 years
- Metal roofing: to 50 years
- Tile roofing: to 100 years
- Slate roofing: to 150 years
But this can change when weather factors play a role.
Weather Effects on Roofs
Extreme Conditions
Extreme sun, cold or moisture conditions can reduce how long a roof lasts in Northern Virginia.
Roof Positioning
Roofs with a southern orientation gather more heat and damaging UV rays from the sun, and materials on that side of the roof can deteriorate more quickly.
Roof Colors
Darker roof colors will absorb heat, also leading to deterioration.
Storms
Storms can damage roofing materials with winds, flying debris and fallen tree limbs. Hail is one of the biggest threats to roofs, and can break or crack brittle materials, allowing water and snow to seep into fissures. When this water refreezes, its expansion can cause further damage to shingles and tiles.
Roof Pitch
Even the pitch of your roof can affect how long a roof lasts in Northern Virginia. Flat roofs do not shed water easily, allowing it to pool on materials and potentially leak into small fissures.

Roof Maintenance Affects a Roof’s Longevity
How long does a roof last in Northern Virginia?
It can depend on the quality of roof maintenance the homeowner performs.
- Homeowners must regularly check the roof for damaged or missing roofing materials, especially following a storm or bout of extreme weather.
- Clear away fallen debris and replace or repair areas where the roof may have been compromised.
- Check for dents, fungus or mold.
- Inspect the flashing around the chimney, vents and skylights for rust or damage.
- Wash out gutters to avoid ice dams.
- Go into the attic to inspect the roof from the inside. Are there visible signs of moisture, water staining or leaks? Use a flashlight to examine corners. On a sunny day, look for areas in the attic where pinpoints of light may be shining through. These can indicate a damaged area of the roof not noticeable with an exterior review.
- A roof must be ventilated in order to control moisture. Without proper venting, moisture can accumulate, creating ideal conditions for deterioration and mold.
