device eaves, their use and purpose

overhang called the lower part of the roof projecting beyond the level of the walls of the house.It protects the foundation and walls of the rain.Its width can vary from 40 centimeters up to a meter.In principle, according to the rules of construction does not necessarily produce a file of this part of t

he building.

However, it may occur some trouble.For example, a strong wind, crept side by an unprotected roof overhang can simply rip roofing.Yes, and I want to hide the underside of the roof with all its layers of "pie" - waterproofing, insulation and the ugly underside of the rafters.According to the rules sutured roof after all the work on the installation of the roof.Also, before warming to be held all the external walls and trim.E. It is a kind of filing the final stage of construction and exterior of your home.

gables and eaves, and the difference between them

There are two kinds of overhang - horizontal, they are called eaves and gables.Eaves is formed the bottom of the pitched roof and gable overhangs - a sloping overhangs formed part of the side slope.

# 1. eaves.

It is the lower part of the sloping roof, facilitating the passage of air into the attic.This is typical of the type of attic roofs.But from the air through the attic roof overhang enters into the "roofing pie" - where the air gap.The air then continues on his way up to the ridge.That's what happens roof ventilation.

Now imagine that the overhang is tightly packed, for example, boards.It will be wrong - ventilation will not be implemented.However, if a file of the roof did not do, you will be able to climb up the roof under the mouse to fly a bird or insect.Rafters will need to protect the paint, and the mist and moisture will damage them.

Attention!From all of the above, we conclude that the filing of the eaves do not need tight and ventilated.

this most ventilation can be done in several ways:

  • most basic option - to leave a gap between the wall of the building and binder.If the binder is used corrugated board, this gap should be between 0.6 and 1.2 centimeters, for lining or siding - from 1 to 1.5 centimeters.
  • For such options Binder eaves of the roof, as the metal sheet, plate, or you can use ready-made linings air vents, which are mounted in the material.
  • If overhang clapboard, ventilation make the gaps between them, from half a centimeter to centimeter.
  • Using spotlights, you can apply a perforated material created specifically for this purpose.

Rule № 1. In terms of the vents can not be less than one five hundredth of the entire area for ventilation.This roofing bitumen and seam type requires a larger diameter of the holes than the clay tile roof.After all, the last still "breathes".

Rule № 2. All openings for ventilation gratings need to cover.If this gap, the use keeper.Such a measure will protect them from dirt, leaves, insects and birds.

# 2. gables overhang.

He formed part of the side slope beneath the slope.There is nothing to worry about ventilation is necessary, but about the proper protection from wind and moisture care should be taken.Otherwise, a strong wind blowing in gusts could drive the rain between the boards lathing, which protrude outward.And this is serious, because it can get wet insulation, no longer retains heat well.

Attention!Therefore, when working with the finishing gable overhang to the fore the leak.

Gables overhang

Finish edge overhang

Both types overhang the ends are unsecured items.At the eaves end is part of the rafters and eaves to gable - ends of the battens.It is necessary to arrange them neatly, while protecting it from the weather.In addition, the cornice overhangs require you to install them along the gutters drain.In general, the finishing end of the overhang - this is the finish edge.And what is it to do, it depends on the roofing material, which you have applied.By the way, often complete with a roof covering is already available and set for registration and zazhity edge.

Before producing binder eaves of the roof, it is necessary to cut vertically on one line, all protruding rafters or fillies.Trim them must be strictly the same distance from the wall.Then the ends of rafters combined strapping board, which beat the frontal board (usually a metal).The front board usually is complete with metal, ceramic and shingles.Make this piece of wood and covered with paint or composition for protection.It is on this board in later mounted gutters.

gables overhang so treated.First, cut the board crates projecting the wall.The line cut should be parallel to this wall.End board (wood or metal) nailed to cut off the edges of the batten and to the end of the ridge beam.The material for the roof over the length equal to the length of the cornice, cover the end portion of the board.

The front board

two main ways filing overhangs

Variety of options for filing eaves large.This can be done perpendicular and parallel to the eaves, use whole sheets or individual strips, use different materials and construction fixing parts.However, in fact only two binder technologies.

Filing overhang directly on the rafters

This is probably the easiest.The main thing - that the plane at the lower ends of the rafters was a general.This method is suitable primarily for small roofs with a slope not greater than 30 degrees, and the removal of no more than 40 - 50 centimeters.Stitched on the crate made of boards or bars and bolted to the rafters.Blindstitch strips can be positioned parallel to the wall, at the ends of the rafters, and you can write and perpendicular to the plane of the rafters.

Filing horizontal

It is indispensable when the roof of a steep slope.This installation is quick and material savings.To work it is necessary to build the boards of the so-called box, attaching it to the wall and to the rafters (top and bottom).To water, hitting the overhang could easily drain, a bar, located in the rafters should be a centimeter below the timber wall.From the corners of the roof to the corner of the house nailed boards.When the overhang is more than 45 centimeters, it will take another one in the middle of the longitudinal beams.The rest of the rails reinforce bars, stuffed them perpendicular to the wall.

Crate a horizontal trim overhang
Mounting example for horizontal batten trim overhang.

Filing gable overhang - always crate

You do not pay attention to the method of filing the eaves overhang.Right on the crate fastened beams or boards.These strips or planks, running along the pediment, attach sheathing strip.

materials for filing

choosing material for covering eaves, you need to reconcile this with the style of the house.Agree - not particularly aesthetically pleasing looks filing white plastic roof, if the house is wooden, and even the dark.

board - better planed, but fit and edged

better to take the boards softwood, width from 5 to 25 centimeters, and a thickness of 1.7 to 2.2 centimeters.Before installing the necessary antiseptic treatment, varnish or paint.Before the work necessary to give the board a month to lie on the street under a canopy - or if it is too dry or wet, then it is warped.

Sheathing overhang between the boards doing the gap in half a centimeter or ventilation.When installing the boards are fixed perpendicular to the wall of the two sides (if a wide overhang, then in third place - in the center of the board).If the board is mounted parallel to the walls, fix them every meter.

worth it inexpensive, from $ 120 per cubic meter, or $ 2.2 per square meter.

Cutting board


This material is good that has been processed (in contrast to the boards), and therefore in great demand.To trim overhang need to take water-resistant lining, designed to work in these conditions.As a board, this material is also necessary to hold a month before installation outdoors.Mounting methods are the same as for the board, leaving only a gap is not necessary.Instead, use ready-made lattice for ventilation, at a distance from each other of 1.5 meters.

cost - from $ 6 per square meter.

Wooden wall paneling for the overhangs


Polyvinylchloride (PVC) Siding

for filing needed siding, having protection against moisture.To complete it acquired all the necessary: ​​this band in the form of the letter "P" for finishing the edges and corners of the connection points for mounting brackets, and grilles for ventilation.Strips mounted perpendicularly to the walls are fastened in their two, three or four locations.Number of seats fastening depends on how wide overhang.Attach PVC panels along the roof overhang is not recommended as it is not as hard as the wooden slats and requires a large number of anchorages, and may sag.

cost - from $ 4 per square meter.

sheeting (trapezoidal sheet)

This material is easy to install - it can be putting more planes, but fastened with the same length as the board.Its height profile may be from 0.8 to 2 centimeters.When filing eaves trapezoidal sheet leaves a gap of 0.6 to 1.2 centimeters (depending on thermal expansion).Ventilation do with special grates.

cost - from $ 9 per square meter.

Profiled to overhang



This can be galvanized steel or polymer-coated, as well as aluminum or copper.The thickness of the sheets - from 0.6 to 0.8 mm, and length - up to 6 meters.Ventilation can be ready to insert or lattice or perforated pieces of sheet.Where the cutting line passes, the steel sheets treated against corrosion (for aluminum and copper, is not needed).Less use of such materials - that we need a special cutting tool.

cost - from $ 5 per square meter.

Plywood and OSB

for filing the eaves, take the brand materials that are water resistant.Plates these tough enough, can be installed in large chunks.To do this, make a box of wooden bars - plate screwed to it.Fix them every 1 - 1.2 meters.For ventilation grille crashed ready.Overhang of this material necessarily need to color, otherwise it does not look very nice.

Plywood cost about $ 6.5 per square meter, OSB - about 2 times cheaper.


Filing roof soffit - quickly, simply and reliably

soffits - it trims manufactured specifically for filing overhangs.They can be made from various materials.In particular, such as PVC, steel, copper, aluminum.Having a large palette of colors and different texture, spotlights can be matched to the design of any home.

Included them are the following main parts:

  • soffit panels;
  • frontal straps (except chamfer);
  • profiles J-shaped, having notches;
  • finishing trims.

Soffits and additional elements
Appearance soffit and additional elements may vary depending on the manufacturer and the material of manufacture.

soffit panels are triple, double and single, continuous (for gables) and perforated (for curtain).

It should be noted that the filing eaves soffit greatly simplifies the work.You do not need to attract experienced builders - and most can handle.Cut the strips according to the width of the eaves and fix them perpendicular walls on profiles with slots - that's all a trick installation.

standing strap PVC 10 - $ 12 per square meter, and the mounting strap and chamfer - 5 times cheaper.

Instructions for filing overhangs spotlights

Depending on the manufacturer and the material of manufacture of spotlights and additional elements of the rules on installation of spotlights may vary.Therefore, always familiarize with the manufacturer's instructions.In this case, the filing will be considered eaves using vinyl soffits.

There are several design features mounting panels spotlight:

Options for mounting spotlights

In most cases the installation of spotlights produce horizontal, although in some cases, apply and mount along the rafters.For horizontal mounting is a special crate, how to do it above or below the video instructions.Then the crate is secured all the necessary elements.

Fixing starter J-channel
1. To begin, measure J-channel size required for this is applied across the overhang profile and applied to a label.

Cutting profile grinder
2. Cut the profile to size possible by means of the "Bulgarian", cut it quickly and the cut is straight.

Mounting Profile
3. After that, the profile is attached to the wooden frame using screws.

Measure off and cut batten strips
4. Once all profiles are fixed measure the distance between the two profiles to find out the size of assembly as defined bar.After that, batten strips are cut the desired size.

Insert soffit panel in profile and fastened to the frame
5. To install the strips give birth to her first in the wall, and then in the eaves and fixed with screws to a wooden crate.

Filing a frontal overhang
6. If the binder is not used J-bevel, the frontal part of the overhang is also sutured spotlights.
