Is There a Roof Disaster Lurking Under Your Shingles?

Looking up for hidden trouble
When was the last time you were on the roof? The view of Mt. Hood might be better, but still: That expanse crowning your home needs regular inspection, so it deserves your attention at least twice a year. Before you climb the ladder, stand back and scan the roofline. Hidden trouble is easier to see when you know what to look for.

Is Your Flashing Flush?

Whether it’s metal, plastic, or rubber, flashing is your roof’s best friend because it deflects water from joints and seams. You can see it around vertical vents and chimneys where it protects structural framing. Flashing forms a water-proof barrier with its snug fit, but age and weather compromise its integrity. Because the material defends vulnerable areas of the roof, its failure can lead to serious structural damage. Even small flashing leaks allow moisture under surrounding shingles, which sets the stage for algae growth and wood rot.

Are the Shingles Out of Shape?

Missing shingles shout out loud that you’ve got trouble on the roof, but what do they communicate when they buckle and curl? This odd appearance is common on older roofs and indicates underlying moisture problems, but the shingles aren’t always to blame. A poorly ventilated attic forces damp air upward through the roof’s structure causing shingle material to buckle and curl. The uneven warping traps debris and rain water, and it sets up a natural breeding ground for mold and moss. When healthy shingles lose their shape, your roof loses its protection.

How Bad Is the Weather?

It’s tempting to blame Portland’s generous rainfall for our roof problems, but summer sunshine and winter cold take their toll too. The temperatures don’t have to sizzle for UV rays to dry and crack shingles. When melting snow runs off the roof, moisture collects around seams and joints, where it re-freezes and warps flashing. Once roofing materials are damaged, a strong gust of wind on a beautiful spring day can give sudden flight to shingles and flashing. It doesn’t take a Pacific storm to inflict weather damage on your roof.
