Generally, roof flashing is installed under the shingles to create a watertight seal and prevent moisture from seeping in and causing damage. However, the exact placement can depend on the type of flashing. For instance, with step flashing, the shingles and flashing overlap each other, meaning the flashing is technically both over and under the shingles. Flashing also typically goes beneath the house siding and is often not visible from the ground.

Fall is widely considered the best time of year to replace a roof. The moderate temperatures are ideal for roofing crews to work and for new shingles to seal properly. Additionally, autumn weather is often drier, reducing the risk of weather-related delays compared to the rainier spring season.

While spring is also a viable option, the higher chance of rainfall can slow down the project. The main drawback to a fall installation is that it's the peak season for roofers, which can lead to higher prices and scheduling challenges.

To potentially save money, you could consider scheduling your roof replacement during the summer or winter off-seasons. However, both seasons have significant disadvantages. Extreme summer heat can make shingles too soft to handle, while winter's cold, snow, and ice can create dangerous working conditions and prevent shingles from sealing correctly, as they typically require temperatures above 40-45°F.

The most common roof pitch is 4:12, which means a rise of 4 inches for every 12 inches of horizontal run. However, roof pitch varies widely based on roof design, climate, and even the roofing materials you plan to install. Your building type also plays a role, as flat roofs are common on commercial buildings and some modern homes.

Sometimes, a local authority won’t approve a request for a roofing permit. This may be because of incomplete documentation, unclear project plans, processing delays, or insufficient communication. There may also be discrepancies with building codes.
