Sheathing deficiencies created dips and shingle problems. See following pictures for more details.

Water infiltration and damage at all penetrations, allowing water in, under the roof shingles. It caused major damage below the penetrations and terminated at the drip edge under our Gutter Helmets as the water ran down the sheathing. This condition is typical around the home.

Badly damaged, aged, pitted, curling shingles missing at least half of granules showing the age of the roof and detailing the fact that it has exceeded its useful lifespan.

Water infiltrations and staining at the chimney.

Dip in roof and shingles, causing “Backwater” condition and encouraging water to track under shingles and cause damage.

Water infiltration at plumbing penetrations.

Close up showing missing granules due to roof age.

Note: rot at valley termination only. This condition is indicative of a roof that has not been maintained and a roof that is beyond its useful lifespan. This damage relates directly to leaf and debris buildup, causing water to back up under the shingles at the valley terminations. Note that the damage tapers off shortly outside the valley, whereas Gutter Helmets existed throughout.

This problem area of the roof is nearly flat, allowing a backwater condition and water damage at the roof rake edge. Nails in the step flashing are at the wrong location. Nails should be at the upper side of the flashing and cover upper flashing so nails are not visible and water does not leak around nails, just as is done with roofing shingles.

Typical condition of badly pitted shingles and missing granules. This age-related deterioration allows shingles to become porous as the fiberglass mat of the shingles is exposed and can allow water to freely enter the roof.

Wider view of general roof condition and age.

A second valley showing similar damage only at the valley, where leaves and debris were allowed to build up and cause leakage.

Additional dips and water damage to roof at various areas.

Note the curl on the edges of shingles due to aging beyond their serviceable life.

Major plywood deficiencies, which translate into vulnerable shingles.

Major rot, water damage and rusted nails in areas of home on roof where Gutter Helmet did not exist (on gable/rake ends of home).
