How Do I Know If I Need a New Roof?

Spot the Signs Before the Storm: Know When It’s Time

Unsure if you need a new roof?  Before calling a professional, you can assess your roof's condition by looking for these common indicators:

Leaks in the Ceiling or Walls

Water damage is usually apparent through visible brown stains, dripping water, or cracked interior sheetrock or plaster. While cracks alone might not confirm roof leaks, brown spots or actual dripping water are strong indicators.

This is not the kind of texture that will wow and impress.

Aging and Rough Appearance

Typical roofs in San Francisco and the surrounding area have a life expectancy of 20–30 years, depending on materials, installation quality, and exposure conditions. If your roof appears discolored, uneven, or has missing sections—even noticeable via low-resolution Google Maps images – it might have reached the end of its useful life.

Rusty or Loose Flashings and Trims

The edges and intersections of your roof material—known as flashings and trims—are commonly the first to fail on aging roofs. Rust, looseness, missing sections, or damaged edges strongly suggest your roof may soon require replacement.

Cracks at Joints and Penetrations

Pay close attention to joints, seams, overlaps, and penetrations like vents and chimneys. Visible cracking or separation around these areas, as shown in the accompanying photo, indicate your roof's protective capability is compromised.

Wind Damage

After strong winds, if you find roofing materials on the ground or notice visibly dislodged sections, your roof may have sustained damage severe enough to warrant replacement soon.

Damage from Other Work or Falling Debris

Roof-mounted equipment installations, careless foot traffic, falling debris, or tree impacts can all damage your roofing system significantly enough to necessitate replacement.

If any of these issues match your situation, contact Sure Roofing or another roofing professional promptly to discuss planning for your roof replacement.
