Examine the roof from the ground with binoculars or at the eaves with a ladder if you are not safely able to access or walk on the roof.
- Bows and Sags – Start your examination by looking at the ridge and work your way down the sheathing looking for bows and sags that could indicate damaged or improperly supported framing. Smaller areas where shingles sag could indicate the sheathing beneath is deteriorated or the shingles or roofing materials were installed over a hole or void. This can prematurely deteriorate the shingles, cause leaks, or could allow someone walking on the roof to put their foot through the shingles causing damage and injury.
- Slope to Wall Design – The roof should not direct water to a wall or chimney with out a cricket (a ridge structure designed to divert water on a roof away from a vertical structure) being installed. This design usually leads to water infiltration and damage.
- Slope to Slope and Slope to Flat Design – Slope to slope channel water into a valley and can cause water build up, infiltration, and damage. Slope to flat design can cause snow build up at the slope to flat intersect and allowing ice damming to occur water to back up under the shingles causing water damage.
- Water Flow – Look for design areas where water is channeled into an area that is too small to allow water to flow properly. Any issues found should be evaluated and corrected by a licensed and insured roofing contractor.
