easy guide to roof terminology.

4. Allows air to circulate through
the uppermost level of the
home, often the attic, while
keeping moisture, animals, and
other natural elements out.

5. Also known as trim; strips
of formed metal that cover
any seams in the roof (such
as roof intersections, around
sunroofs or vents, or around
the chimney); used to prevent
water from seeping under the
shingles, may also help divert
water into gutters.

6. The outermost part of the roof.
Installed in overlapping layers
on top of the underlayment,
forming the outermost shield
against the elements. Types of
shingles include asphalt, tile,
concrete, wood or metal.

7. Where two sloping roof
planes meet, forming an
inside angle.
Design element structured
around a window that
projects from a sloped roof
for the purposes of bringing
light into the attic or top
level of your home.

8. Also known as tar paper;
a waterproof barrier that is
placed on top of the decking
which offers a layer of
protection from the elements,
including ice, snow, rain,
sleet, etc.

9. Long, continuous strip of
asphalt roofing installed under
the first row of shingles, that
provides an added layer of
protection from wind and
water damage.

10. Layer of base panels that
install on top of the roof
truss; used as base for
chosen roofing material
(shingles, metal panels, etc.);
typically made of plywood or
oriented strand board (OSB).

11. An extra waterproof barrier
that adheres between the
decking and underlayment;
meant to prevent water
damage to the roof caused
by heavy rain, snow buildup,
and ice dams.

12. Type of edging that is installed
at the end of the roof that
helps direct water into the
gutters and prevents runoff.

13. The framework or skeleton of
the roof. Typically composed
of wood beams that provide
support for the roof. See:
Rafters and Ridge.

14. A component of the roof truss
featuring parallel, sloping
beams that connect the top of
the roof to the bottom.
The peak, or highest point, of
the roof truss; a beam that
runs the length of the roof.

15. Trim, often made of wood, used
to cover the rafter ends.

16. The open, overhanging part
of the roof, extending beyond
the side of the home.

17. Also known as an overhang;
the finished underside of the
eaves, which covers the open
area between the siding and
the edge of the roof.

18. System of troughs attached to
the fascia that catches water
running off the roof, and diverts
it away from the home.

19. Helps to keep tree debris and
leaves from entering and
clogging your gutters. Note that
some systems are ineffective,
and will still allow debris to
enter and clog your gutters,
which may damage your roof.
Luckily, LeafFilter has none of
these issues!
