In contrast, if the building site is in a wide-open space or along the shore of an ocean or large lake, where the wind’s approach is unimpeded, the wind-load factor may have to be increased beyond the nominal design value. Inside the hollow portions, the adhesive mushrooms out and keys itself into the unit. There are many different types of awnings, including retractable, portable, or even motorized.

Step 4 Caulk any overlapping seams where the flashing meets or where any nail heads might be exposed. Using them overhead is difficult because dripping may occur. By checking these numbers against the code book’s conversion chart, you can determine a basic wind pressure.
