How long does it take for roof shingles to settle?
The first, and more flexible, is that the outside temperature on the roof must be at least 40 degrees F for 24 consistent hours. The reason for this is that the adhesive strip will not activate and seal the shingle under colder conditions.
Are shingles supposed to flap?
Flapping shingles are harder to spot and fix than missing shingles since they are still in place, but when subjected to high winds, they will flap and settle back down. When shingles start to flap, this is often caused by loose nails or damaged shingles.
What causes a hump in a roof?
Humps are commonly due to intermediate walls that extend up to underside of the roof deck (Figures HS-2). Since walls generally do not sag with the rafters, the sagging rafters around them results in the roof surface over the wall being higher than the adjacent surfaces. The high area is commonly described as a “hump.”
How should roof shingles look?

What temperature do shingles need to seal?
In spring, two to three days of 45 to 50 degree weather with sunny skies would be good for a roof installation. Shingles won’t seal unless they warm to an ambient temperature near 70 degrees.

Can it be too hot to roof?
Roofing in Hot Weather As a general rule, heat can pose a danger to roofing technicians when temperatures climb above 90 degrees. The heat index, which reflects both the temperature and the humidity, means that temperatures below 90 degrees can be dangerous, too.
Do shingles flatten over time?
When the shingles heat up, they become flexible and the adhesive bonds the shingles in place. Before new shingles seal down, they can look a little lumpy and uneven, but once the roof gets hot enough, they should soften, flatten and form a permanent seal.
What causes ripples in shingles?
Ripples can happen if the sheathing is installed without a gap between the boards to allow for expansion and contraction, or if the builder left the sheathing exposed to the elements for too long without covering it with a protective underlayment.
