Parts of a Roof / Roofing Terminology
Built-up Roof
A low-slope (or flat-seeming) roof covered with alternating layers of roofing felt and hot-mapped asphalt and topped off with a layer of gravel.
Cornice
The portion of the roof projecting out from the side walls of the house.
Counterflashing
The flashing which is imbedded at its top in a wall or other vertical structure and is lapped down over shingle flashing.
Courses
Horizontal rows of shingles or tiles.
Deck/sheathing
The surface, usually plywood or oriented strand board (OSB), to which roofing materials are applied.
Dormer
A small structure projecting from a sloped roof, usually with a window.
Drip Edge
An L-shaped strip (usually metal) installed along roof edges to allow water run off to drip clear of the deck, eaves and siding.
Eaves
The lower edge of a roof (usually overhanging beyond the edge of the house).
Fascia
Trimboard behind the gutter and eaves.
Felt
The “tar paper” used by roofer, usually made of a combination of asphalt and either paper or rags.
Fire Rating
System for classifying the fire resistances of various materials. Roofing materials are rated Class A, B or C, with Class A materials having the highest resistance to fire originating outside the structure.
Flashing
Sheet metal or other material used at junctions of different planes on a roof to prevent leakage.
Frieze Board
A Board at the top of the house’s siding, forming a corner with the soffit.
Gable
The triangular upper part of a wall closing the end of a ridged roof.
Hip
The external angle at the junction of two sides of a roof whose supporting walls adjoin.
Joist
In a flat roof, a horizontal structural member over which sheathing is nailed.
Louvers
Slatted devices installed in a gable or soffit (the underside of eaves) to ventilate the space below a roof deck and equalize air temperature and moisture.
Oriented strand board (OSB)
Roof deck panels (4 by 8 feet) made of narrow bits of wood, installed lengthwise and crosswise in layers, and held together with a resin glue. OSB often is used as a substitute for plywood sheets.
Penetrations
Vents, pipes, stacks, chimneys-anything that penetrates a roof deck.
Rafter
A structural member (usually slanted) to which sheathing is nailed.
Rake
The slanting edge of a gabled roof extending beyond the end wall of the house.
Ridge
The horizontal line at the top edge of two sloping roof planes.
Sheathing
The rigid material (often on inch by six inch or one inch by 12 inch boards or sheets of plywood) which is nailed to the rafters, and to which shingles or other outside roofing materials are secured.
Shingle Flashing
Flashing that is laid in strips under each shingle and bent up the edge of a chimney or wall.
Slope
The number of inched of vertical rise in a roof per 12 inches of horizontal distance. Also referred to as pitch.

Grasshopper asked:
I need to replace my current roof. My roof is a flat type roof and I was wondering which type of roofing I should replace it with? Should I use the modified bitumen or the built in roofing with tar/gravel. Which type would last the longest and easy to maintain? I’ve been experiencing some leaks and molding in the house and the roof is in bad condition.

Querious asked:
I am bidding a small roofing job on new construction for a meeting hall. My part of it is just to lay down 1/4″ plywood on a very oddly shaped roof. Someone else will do the rest. Thus, no hauling away, no fascia boards, no metal vents, flashing etc. Just my labor.
I estimate that it will take me six days by myself to do the job. How much should I charge? In other words, what should I charge per man hour here in So. California to do roofing work?

Pros and Cons of Roofing Materials
Filed Under roofing | Comments Off
John Dickinson asked:
Considering the many choices, each with its own pros and cons, it can be a daunting task to decide on the type of roofing for your home. When choosing a roofing style, make sure to pay attention to a few key factors: home design, structural strength, cost, local building ordinances, and personal preferences. It is also a good idea to consider the long term effects of your choice and what it will mean for your home in years to come.
Below is a quick look at a number of roofing types, accompanied by their main advantages and disadvantages.
Composition Shingles
Pros:
At a very affordable price, these roofs are offered in a variety of colors and styles. Composition shingles made from asphalt and fiberglass are of a high quality and very durable. They are easy to install compared with other roofing types, require little maintenance, and usually have Class A fire protection.
Cons:
These types of roofs do not perform well in high winds, and under certain conditions there is a chance that they might blow off. The materials also scar easily if hot, which damages the appearance and durability of the roof.
Wood Shakes
Pros:
Available in a variety of colors, widths, thicknesses, cuts of wood, etc. – these roofs allow for flexibility in style. Wood helps to insulate your attic, which allows air to circulate easily.
Cons:
Wood shakes are unrated by fire safety codes and often require wipe or spray-on fire retardants, which are usually less effective in fire resistance than other roofing materials. These roofs require much maintenance and repair due to damage from mold, rot, and insects. Old shakes are not recyclable and have a more complicated installation process than other roofing types.
Clay Tile
Pros:
Provides a unique look, especially for homes with a Spanish, Italian, or South-Western look. A wide variety of colors and styles are available. Tiles are long-lasting, don’t rot or burn, and cannot be damaged by insects. This roofing material requires little maintenance.
Cons:
Tiles are heavy, which can cause a roof to require extra support. Also, if color is only added to the surface of the tiles, it can fade over time. Tiles are fragile, which makes it more difficult to repair the roof or walk on it to repair gutters or fireplaces. Clay tiles are one of the most expensive roofing materials, and installation can be quite complicated.
Concrete Tile
Pros:
This roof type is very durable is available in a variety of colors and styles. Most concrete roofing is long-lasting and requires little maintenance. Tiles are resistant to rot and insect damage and provide good fire protection. Concrete tile can be made to mimic other types of roofing.
Cons:
This roofing style is on the expensive side and because it is relatively new on the market, there are still problems with breaking and color changing that must be resolved.
Metal
Pros:
Regaining its popularity, metal roofs are now most popular in standing-seam steel (Standing-seam steel describes the upturned edge of one metal panel that connects it to adjacent sections, creating distinctive vertical lines and a historical look). These roofs can also be created to mimic other roofing types such as wood shakes, clay tiles, shingles, etc. Metal roofs are durable, fire retardant and require very little maintenance. Metal roofs are energy efficient and consist of many recyclable materials. They are light weight, which means they can be installed over existing roofs.
Cons:
Installation of metal roofs can be difficult and the cost is higher than most other roofing types. The life-long cost of the roof should be considered to determine if the initial cost is worth it.
Hot Mop-Flat
Pros:
This roofing is most used in commercial buildings or flat homes with good drainage. Made of asphalt, it is less expensive than other roofing types and is very durable. Although the result is not as aesthetically pleasing as other materials, it can be covered with a layer of stone to achieve a more desirable look.
Cons:
The installation of asphalt can be harmful to the environment and the installers. Some urban areas do not allow hot mop roofs because its fumes contribute to smog and release extremely high levels of air pollutants.

Don’t Let Your Roof Repairs Go Sky High!
Filed Under roofing | Comments Off
Virginia Wherland asked:
Before you go to the expense of calling in a roofing contractor, see if you can analyze and repair your roof problem yourself. The best possible time to repair your roof problem - is as soon as you realize that you have one and if the weather is calm enough to climb up onto the roof. In fact, this could be further qualified by saying that the best and most economical way to a trouble-free roof, is to inspect the roof regularly, so that you see the problem developing.
A leak from one dislodged tile is a small and inexpensive matter, but if you do not inspect your roof regularly, this will go unnoticed. By the time that you DO notice it, it may be because water is dripping into your spare room! This means that this whole area of the roof structure is soaked, the ceiling will need to be replaced and hopefully the flooring will recover.
Always check your roof after a wind storm, as most roofing is not designed to withstand fierce winds. Scrutinize the tiles for cracks, splits and torn-off corners; also check for lifting. Lifting is a common cause of roof leaks, and can be easily rectified. Be aware of multiple tiles lifting, as this could be a sign that the roofing material is too old and is warping from all the weathering.
Climb into your attic/loft and ensure that any insulation that you have in your roof is not right up against the roof itself. There has to be a gap for air to circulate; also when a roof heats up and there is insulation directly behind it, this heat is thrown back into the roofing and excessive heating like this can damage and warp the roof.
Another weakness in all roofs is the flashing. Flashing is designed to provide a watertight junction between roof materials and structure, especially if the roof projects out or changes design (as with extension roofs). If you are installing a new roof, it is worthwhile to get the flashing ‘inspected’ as it is a common failure area.
Often the simple fact that the gutters, leading into down pipes from the roof, are blocked with leaves and twigs can cause a problem. Roofs must have adequate run off, especially in the areas which may have snow. Water trapped in the gutter will mean that it will back up the roof for a few inches and have time to seep into the edges of the roofing tiles. Not all homes have adequate perimeter protection on their roofs, although this is one good feature to ask for on a new roof.
Quite often homes incur roof leaks all at the same time (often after strong gales winds and torrential rain etc). This can mean that all contractors are busy and you have ’stop up the leak’ until you can get help.
If you do get a leak, and you have placed buckets under the dripping water, be aware that the leak may be in a completely different place than it would seem. Locating the source is difficult, as water can run along horizontal timbers and appear to be leaking from a place that is sound. Getting up into the attic and actually looking for a wet spot on the roof decking will be an accurate way to tell.
If you can find the spot an emergency patch can be made applying roofing felt and using plastic cement to hold it until you can call in a contractor. You can also attempt to repair it yourself, if it is just a shingle that is damaged. You can carefully prize up the roof shingle by removing the three or four nails that are holding it in place; next, apply a generous coating of tar beneath the tear in question, and also coat the underside of the shingle with a with a coat of tar before putting it back in place. Add a spot of tar to each nail head. Most roofing companies advise against the ‘liquid’ asphalt repair products.
Roofs can also be temporarily repaired using roof membrane and sealants. Care must be taken to clean the roof surface first to ensure that the sealant will stick and keep the leak protected from rain etc. In fact, as long as the roof is clean and dry, the wonder of the 20th. Century - duct tape - can also be stuck onto the roof!

Is a New Roof in your Future?
Filed Under roofing | Comments Off
Dan Fritschen asked:
Purchasing a home is the single largest investment that most of us will make. The roof of our house plays an important role in preserving our house and maintaining its value in the resale market. The life of the roof depends on the roofing materials used, the local weather conditions, care taken during the installation process and the level of maintenance applied to it. Asphalt and wood shingle roofs can last for 30 to 40 years, respectively. Clay tile rofs have a lifespan of 20 years whereas metal roofs can last for more than 40 years.
The sun has a detrimental effect upon the roofing material, regardless of what type of roof it is. The rays cause the material to expand, contract, warp, curl, and lose strength and shape. Elements such as rain water, high winds, snow, hail, etc cause further damage to the already weakened roof resulting in leaks, damage, mildew and fungus growth.
If an inspection of a roof reveal that there is a leakage problem at several points and that the shingles are worn out, replacing the roof is a better idea than making repairs. A new roof offers the benefits of providing sturdy protection for your house preventing damage to the structural systems inside the home from leaks as well as a new roof can provide improved insulation and a change in the appearance of your home.
Types of roofing materials
There are many different types of materials that are used for the purpose of roofing.
Wood Shingles
Wood shingles are usually made from western red cedar and are popular because they are easy to manufacture, light weight and have a very distinctive appearance.
Asphalt Shingles
Asphalt is one of the most commonly used roofing materials around today. It has a lifespan of 15-25 years. Asphalt shingles have a fiberglass body that is coated with asphalt and mineral granules for added protection. When the edges of the asphalt begin to crack and warp, it indicates that age has caught up with the material, which is beginning to dry and may no longer be a good weather proofing material. Asphalt shingles are easy to install and can be used with a variety of flashing and edging products without any special accessories for roof edges, wall cuttings, and chimneys.
Tiles
Tiles can be either ceramic, clay, or concrete. Ceramic tiles are favored in warmer climates. Tiles lend style to the roof but are difficult to install because of their weight. The roofs need to be reinforced before tiles can be laid out.
Corrugated Metal
Corrugated metal is very durable and will last upwards of 50 years with periodic maintenance, they need to be painted and protected from moisture. Metal roofs are available in sheets at home improvement stores in a wide range of colors and can be crafted to give the appearance of traditional tiles. They are sturdy and durable.
Slate
Slate is another durable roofing material that is almost non-absorbent. Slate has been used for centuries. It is a naturally occurring product that is resistant to wind, sun, rain, and other forces of nature. Its gentle colors and unique textures coupled with its durability offer a great mix of utility and beauty. However, slate roofs are difficult to install and the material is expensive.
Cost comparison between roofing materials
Factors affecting the cost of the roof include the area to be covered; the material used, layers of shingles placed; effort involved in removing the existing roofing; and any work required on the gutters and siding. The cost of roofing materials is usually quoted in terms of squares. One square is equal to an area of 10 feet x 10 feet.
Costs of common roofing materials are given below. These costs are exclusive of the installation charges.
Fiberglass coated with asphalt:

Metal roofing can be completed in 2 – 4 days.
Can a homeowner do the roofing by himself?
Some types of roofs lend themselves more easily as a do it yourself project than others. Roofing is a very physical job that requires a fair amount of brawn and some brains too. The work involves moving a lot of material and nailing it in place, installing the flashing requires skill. If you wish to get it first-time right, it is advisable to take the help of someone who has done it before. A roofing project requires the efforts of more than one person. An important consideration is the weather, if you get a spell of clear weather, try and finish the work, if the weather changes you must be equipped to protect the unfinished roof against the elements. Also, you need to be careful about your own safety while handling various tools, a slip from roof height is potentially fatal.

Purchasing a home is the single largest investment that most of us will make. The roof of our house plays an important role in preserving our house and maintaining its value in the resale market. The life of the roof depends on the roofing materials used, the local weather conditions, care taken during the installation process and the level of maintenance applied to it. Asphalt and wood shingle roofs can last for 30 to 40 years, respectively. Clay tile rofs have a lifespan of 20 years whereas metal roofs can last for more than 40 years.
The sun has a detrimental effect upon the roofing material, regardless of what type of roof it is. The rays cause the material to expand, contract, warp, curl, and lose strength and shape. Elements such as rain water, high winds, snow, hail, etc cause further damage to the already weakened roof resulting in leaks, damage, mildew and fungus growth.
If an inspection of a roof reveal that there is a leakage problem at several points and that the shingles are worn out, replacing the roof is a better idea than making repairs. A new roof offers the benefits of providing sturdy protection for your house preventing damage to the structural systems inside the home from leaks as well as a new roof can provide improved insulation and a change in the appearance of your home.
Types of roofing materials
There are many different types of materials that are used for the purpose of roofing.
Wood Shingles
Wood shingles are usually made from western red cedar and are popular because they are easy to manufacture, light weight and have a very distinctive appearance.
Asphalt Shingles
Asphalt is one of the most commonly used roofing materials around today. It has a lifespan of 15-25 years. Asphalt shingles have a fiberglass body that is coated with asphalt and mineral granules for added protection. When the edges of the asphalt begin to crack and warp, it indicates that age has caught up with the material, which is beginning to dry and may no longer be a good weather proofing material. Asphalt shingles are easy to install and can be used with a variety of flashing and edging products without any special accessories for roof edges, wall cuttings, and chimneys.
Tiles
Tiles can be either ceramic, clay, or concrete. Ceramic tiles are favored in warmer climates. Tiles lend style to the roof but are difficult to install because of their weight. The roofs need to be reinforced before tiles can be laid out.
Corrugated Metal
Corrugated metal is very durable and will last upwards of 50 years with periodic maintenance, they need to be painted and protected from moisture. Metal roofs are available in sheets at home improvement stores in a wide range of colors and can be crafted to give the appearance of traditional tiles. They are sturdy and durable.
Slate
Slate is another durable roofing material that is almost non-absorbent. Slate has been used for centuries. It is a naturally occurring product that is resistant to wind, sun, rain, and other forces of nature. Its gentle colors and unique textures coupled with its durability offer a great mix of utility and beauty. However, slate roofs are difficult to install and the material is expensive.
Cost comparison between roofing materials
Factors affecting the cost of the roof include the area to be covered; the material used, layers of shingles placed; effort involved in removing the existing roofing; and any work required on the gutters and siding. The cost of roofing materials is usually quoted in terms of squares. One square is equal to an area of 10 feet x 10 feet.

I have picked some steel roofing out and I was wondering what price range I should expect to get. I have two very simple gable roofs one is 17sq. and the other one is 8 sq. I am planning on going over existing shingles, so no removal is needed. I am going to purchase all the materials at a local steel supplier.
