Shingle blow-off often starts at the eaves, as shown here after exposure to 115-mph hurricane winds.
Image
Shrubs, trees, and herbs create a tight network of roots and stems that bind the soil and slow the flow of water down hillsides.
Image
Side by side comparisons of standard roofing colors (top row) and cool colors (bottom row) shows that solar reflectance (R) can be reduced significantly using special coatings with almost no change to the color

Image
Stone cladding system with a drainage mat provides a small, vented gap (≤ ¾ inch), over a water-resistant barrier house wrap that has a perm rating of 10 to 20 perms so it can serve as a vapor throttle.
Image
Storm-blown shingles reveal that the starter strip was incorrectly installed; rather than cutting off the tabs of the starter, the starter was rotated 180 degrees (right arrow) so the exposed portion of the first course of shingles (left arrow) was...
