Got a problem roof?

Here's some information about common roof problems...and helpful suggestions on fighting them!



Chalking

Chalking is a powdery residue on the roof surface resulting from degradation of that material from exposure.

Mildew, Moss, or Mold

The three M's, Mildew, Moss & Mold, are usually fuzzy, greenish or bluish-grayish-white and THEY'RE ALIVE!

Alligatoring

Alligatoring on a built-up roof (or BUR) is term for a pattern of cracks similar to an alligator's skin.

Badly Degraded Built-Up Roof

If your roof looks like this, see a roofing professional and have it replaced. This is what happens to asphalt if it's left exposed and unprotected.

Blistering

Like blisters on your skin, blisters on a built-up roof (or BUR) occur when water gets trapped under the top layers of the surface.

Loose Lap

Pictured at left is a condition known as loose lap. It occurs on rolled roofing.

Cracked Flashing

Flashing, stacks, vents, and other protrusions are prone to cracking, which can eventually cause leaks.

Fishmouthing

Pulling felt during application, using felt with damp edges, or flattened rolls may cause laps to lift or have scalloped, wavy edges. This condition is known as "fishmouthing."
