A dormer is a small piece of roof that projects from or is not in plane with the main roof plane. It has a junction with the main roof and this junction is where the flashing is required.
Dormers can vary in shape, so the exact form of flashing required will vary. The type of flashing also depends on the roofing material, and whether the same material is on the main roof and the dormer roof.
If the main roof plane and the dormer are of the same material, the flashing can usually be the same as used on a similar junction of the main roof.
Important parts of a basic flashing are:
* it laps from under the upper or higher roof cladding so that water will run down onto it from the higher cladding, and it laps over the lower roof cladding so that water running down it will run onto the lower cladding, rather than underneath the lower cladding. Flashings that run parallel to the fall of the roof are a little different but follow the same principle: look at the path the water will follow. * It is lapped a sufficient distance under and over the cladding to prevent water seeping back. This distance will depend on the roofing material, the material's profile, the strength of wind in the area and the rainfall of the area. * It may also need a return or kickback on the flashing to prevent capillary action or wind driven moisture. Flashing materials must be compatible with the roofing material. Water running over some materials will collect ions that may make materials that this water then runs onto be stained or corrode quickly.
There are two meanings for a roof aprona flashing material, similar to a drip edge, that is installed at the bottom of a roof, channelling the run-off away from the fascia and into a gutter;a flashing along the edge of a roof where it butts into a wall that goes higher than the roof. The flashing directs water away from the wall and onto the roof.

NO - there are special paints for paving -after all, how often do you walk on your roof . In addition, some roof paint has chemicals to prevent moss from growing there, and it is rough like sandpaper.

Tensile roof is a tension membrane roof made of fabric. It's used to cover modern-looking pre-fabricated buildings with low energy consumption. You can find examples of tensile roofs at http://fstructures.com
An apron flashing is a term used for a flashing located at the juncture of the top of a sloped roof and a vertical wall.
A type of flashing not typically found around chimneys is roof valley flashing, which is used to protect the intersection of two roof slopes from water infiltration. Chimneys usually have step flashing or counter flashing to prevent water from entering where the chimney meets the roof.
Step flashing is used in two applications on roofs. 1) Around skylights/roof windows (eg. Velux). 2) Around the base of chimneys.

When installing a skylight in a tile roof, a specialized flashing system designed for tile applications is used. This typically includes a combination of step flashing and counter-flashing to ensure proper water drainage and prevent leaks. The flashing is integrated with the tiles, often requiring the tiles to be cut to fit around the skylight, ensuring a watertight seal. Additionally, underlayment may be added for extra protection against moisture.
They ARE used when quality and longevity is needed for leader lines, roof drain flashing material
it is used around the edges of the roofactually, it's used in the valley's and anywhere the roof meets an outside wall... drip edge is used on the edges, except in areas where precautions must be taken against ice-dams.Flashing is also used where anything passes through the roofA windowA stink pipeA flueA chimney stackA vent from a cookerA vent from a bathroom with no outside window.A drain in a flat roofIt is used anywhere there is a protrustion in the roof. Flashing can also be found around hvac units, scuppers, etc...
Chimney flashing lead is used to create a watertight seal between the chimney and the roof. It helps prevent water leaks by directing water away from the chimney and roof intersection, ensuring that water does not seep into the home through gaps or cracks.
The horizontal seam between two panel siding loads should have what flashing?

Kick out" flashings are intended to prevent water from flowing behind a wall or down a vertical surface such as the fascia below a roof's edge by redirecting it a short distance sideways and onto a roof surface or into a gutter
You get things like corn catapult, cabbage pult, melon pult. Things that are used in the roof level.
