Flat Roofs

Flat Roofs

Excessive water and puddling on flat roofs indicate structural problems. To fix these problems there are roofing solutions that should be employed. There should always be a slight pitch for quick drainage of water and when sunken areas appear from time to time it is important to determine the problem and find out the structural problems. After determining the structural problems there are professional fixes for flat roofs, and what you use will be determined by budgets, structural damage, and time.

 

Flat Roof Fixes

You can raise sunken areas on flat roofs with a range of liquid and sold roofing materials. You can also use roof putty, felt or asphalt mixes.

• Liquid patching materials on in a variety of types and strengths. You can use roof patch putty and apply, using a trowel, to fill low areas. Use universal epoxy concrete packing and spread mastic on the top using a trowel. An elastic sealant or mastic adheres to almost any substance. You can also use flexible mastic applied with a trowel on its own to fill and resurface an entire roof. Do review the manufacture guidelines for the best application rates.
• Fixing low spots with sheet fillers is essential re-roofing the trouble spot. Older style flat roofs were often planned with pieces of asphalt felt between tar layers. In these types of felt roofs it is possible to fill low spots with more felt and apply with tar. Use the type of felt most compatible with your roof. You can also use asphalt or gravel cap sheet and sheet roofing materials on top of the felt. Newer flat roofs are made of rubber and these same rubber materials can be used to patch low spots and leaky roofs.
• Asphaltic fillers can also fix low spots on roofs. These fillers are mixtures of sand or other lightweight aggregates combined with asphalt material. Use these fills with gooey asphalt roof coating that waterproofs and protects the roof. This form of application is idea for flat roof made of concrete, metal or asphalt. Cover all application with gravel or tar to mix in with the exiting roof composition.

Overview

As a summary, make sure when repairing low spots or dips in flat roofs you determine the cause of the problem. Weakened sheathing, sagging simulation and rotting joists are some causes of low spots on flat roofs. If you have structural damage it may be best to tear apart the offending section and complete rebuilt it then apply the roofing materials and fixes. Make sure the appearance of puddles on the roof is not caused by drainage problems. Ensure drainage outlets are cleared and drainage systems are functional. After cleaning and fixing, then re-roof. Roof and roofing materials should never include tile for sloping roofs or flat roofs. This type of roofing material will not fix low spots adequately.

Heavy Roofing Materials

Buildings keep cool through air condition, open windows, but most of all the roof. On a hot day the roof should release not store and absorb the sun’s rays. Traditional roofing materials hold and transfer heat and can transport the heat it downward into your home, but there are other types of roofing materials that will actually reflect light and heat upward which keeps air conditioning costs down. There many roofing options to keep your home cool and safe; research the best for your situation.

4 Roofing Materials that Keep you Cool, but are Heavy

1. When you use a hat or an umbrella to keep the sun of this is similiar to what roofing can do for a building. Cool-roof coatings and roofing materials have advanced in the past few years. Elastomeric sealants that include sprays, ceramic-based pain and recycled cooking oil tratments have been used and actually do help keep buildings cook when applied to roofs. Another method is installing under-the-roof materials that involve installing reflective material in an attic between the interior and the roof. These barriers reflect heat away from the home.
2. Roofing with tiles and particularly slate tiles is a centuries old style that uses durable and natural materials that last forever with very little maintenance. Light colored slates help reduce the heat absorbed by building because of natural reflective properties. As time goes on, slate wears to a beautiful finish which adds high value to your home. Slate tile roofs, however are extremely heavy and very expensive. Slate is beautiful but is hard to transport and breaks easily when being installed.
3. Terra cotta and clay roofing materials have been used in Mexico, Italy, America Southwest and Spain. You will find many subdivisions of homes with red clay roofs that are highly attractive. Basic clay or terra cotta roofing materials are general light in color and do not retain heat. If you install modern clay tiles you will find that there are paint treatments that make tiles look like expensive slate. This painting adds weatherproofing to the tiles. Clay and terra cotta tiles are generally ‘s’ shaped which helps to hold in water and air to further cool buildings and homes. You will find that clay and terra cotta roofs are very heavy and need load bearing foundations. Cold and wet weather will make tiles snap; check for temperature resistance.
4. Concrete tile is an option for weather durability. Concrete, however, is heavy but does take quite a bit of time to heat up which makes it ideal for warm weather roofing. Poured concrete slab roofing is lower cost and provides protection from weather and pests. Often poured concrete roofing is the under-layer in more expensive homes. Tile concrete is heavy but it is easier to install than poured concrete, is fireproof, solid  and can be dyed to almost any color. Using cool colors with concrete tiles will increase the cooling properties and help the concrete tiling reflect the sun’s rays.

Popular Choices - Roofing Materials

Your choice of roofing materials mainly depends on where you live, your own personal taste, local styles and building codes. You need to be aware that if you want a thatched roof in New York City, that just won’t happen, but if you live in the South; maybe you can have a thatched roof. Choosing roofing materials and shingles is the time to consider costs, fire retarding abilities, and how long your shingles will last.

Types of Popular Roofing

The most popular used shingles for roofing are asphalt composition roofing shingles which are attractive, cost effective, long lasting and have high fire retarding properties. Asphalt shingles generally have 20 to 30 year warranties and may last even longer than the 30 year warranty.

Asphalt composition shingles in modern construction are thicker and more textured than ever before. You can get asphalt composition shingles that look like wood or slate. These types of shingles are called architectural shingles, but are higher in cost than less trendy shingles.

Asphalt shingles are easy to install and go up much faster than any other type of roofing material. The downside, or maybe this is not a downside, they can be installed by any Saturday roofer with the minimum of experience and expertise.

Wood shake roofing materials are gorgeous. They look fantastic, make your home higher in value and when they weather they look very rich. Wood shake materials are organic, but they can last for up to fifty years if properly maintained. Wood shake roofing is produced mainly from cedar and redwood, but you can also find pine wood shake roofing material that is a bit lower in cost.

Metal roofing is somewhat rare, but it is gaining popularity as a roofing material. You do need to find a roofer who specialized in metal roof installation. Trying to use fancy copper roofing material will provide a gorgeous and timely roof, but it is also very expensive and difficult to work with. Galvanized sheeting roofing materials are a better choice and will last up to 75 years. This long lasting type of roofing material makes it highly popular for homeowners who plan on living in their homes for life.

Composition slate roofing materials are similar in look to traditional slate but are less expensive and environmentally friendly. Composition slate is made from post-industrial synthetics; basically recycled materials. Composition slate is about one-third the weight of regular slate and looks almost the same; unless you get on the roof and inspect the tiles!

Another highly popular roofing material is ceramic or “Spanish style” roofing materials. This type of roofing is losing popularity because of its weight and expense. This type of roofing is called a half barrel tile since it is basically a cylinder cut in half. The space between the tiles does provide for water and air circulation which helps in cooling, but the tile can break and are somewhat difficult to re-install. Ceramic, clay and terra cotta tiles are highly fire-retardant, but other less costly roofing materials are also fire-retardant and can be highly attractive as well.

Roofing and Roofing Materials – Tearing off a Shingle Roof

Slate roofs will last for hundreds of years and a steel roof may be good for up to fifty years, however most generalized roofing materials have a life span of about 20 years. If you find that your roof is over twenty years and you live in a harsh climate, or you see your shingles cupping or cracking you should consider replacing your roof.

Most professional roofers will encourage you to tear off the existing roofing materials to check the condition of the deck before re-roofing your home. That’s very good advice but in most localities you don’t have to remove the old roof before installing a new one. Building codes in most areas will permit asphalt roofers to install over the original shingled roof and two reroofs. Wooden shingles can include one re-roof. Do make sure and check your local building codes to find out if you need to remove your old roof or if you can install over your old roofing materials.

Tearing off a shingle roof

If you are going to install a new roof over the old roof, you need to inspect the situation of your roof deck from inside the attic. Look for signs of rot or water leakage. If you find that there are problems you need to replace those problem areas before installing your new roof. If the existing roof is in poor condition or it has too many layers you will have to remove it.

1. To tear off an old shingled roof you need to have several contracting and roofing materials on hand. These include an extension ladder, screw driver, pry bar and roofing shovel. You will also need a safety harness and ropes as well as a rented dumpster. It would be very advantageous if you had large tarps, work gloves and a bar magnet.A dumpster is needed to haul away the old roofing materials. Protect your lower windows and flower beds from falling shingles by positioning sheets of plywood against the side of the house. Spread tarps on the ground to catch falling shingles.
2. Begin at the roof line, remove the ridge shingles and remove all the nails.  Once the shingles on the ridge are gone it is time to remove the other shingles.
3. Shove the roofing shovel under a shingle, catch on a nail and push the handle down. When you lever the handle down this raises the point of the shovel and lifts out the nail. Now the old shingle is free and falling.
4. As you remove the nails shingles will slide off the roof. Hopefully they will land onto the tarps where they can be picked up and placed into the dumpster. 
5. The original metal flashing in valleys or around chimneys does not have to be removed unless the flashing is in poor condition. Use a pry bar to very carefully remove the nails in the flashing and save the old flashing for use as a model to cut and reform new flashing.  
6. When all the shingles have been removed double check the roof to ensure all the nails are removed. Check the roof deck for any damaged areas that need repairing. It might be fun at this point to install skylights or additional venting.

Roofing Techniques - Roofing and Roofing Materials

Roofing Techniques

There are specific roofing techniques you need to use to ensure that your roofing project meets code and quality standards. These techniques definitely apply to re-roofing, new roofs, or roof repair. Depending on the job you are doing there are specific tools, techniques and materials needed to accomplish your task.
First you will have to follow local or municipal guidelines and laws. You cannot just roof any way you want ... roofing has to meet building codes.

Other guidelines include your own personal preferences plus the type of home or building you have. To determine the best implementation process and to protect the life and functionality of your new roof, work with either a contractor or a lumber company with roofing expertise.

Steps to Laying down a new Roof

Roofing techniques follow a fairly standard process. The first layer of your roof is the sheathing. These are plywood sheets you can see attached to the rafters in your attic. Plywood sheets provide the foundation where the rest of the roofing system is built.

The second layer is the underlayment. Different types of materials can be used for this step and the most common is builders’ felt. This second layer is required in most building codes and provides added protection from the weather. Third the valleys, eaves, protrusions and rakes get an application known as flashing. Flashing directs water away from vulnerable sections.

The last step in roofing is installing the outer covering. This includes many different varieties of materials and styles like asphalt shingles, wood, metal, slate or ceramic. Know what you want and choose a contractor who is an expert roofer and knows how to use different roofing materials. By going with an expert you are guaranteed that the proper techniques for installation and roofing are carried out.

When re-roofing an asphalt surface, check the sloping edge to find out how many layers are currently on the roof. There are building rules that specify the number of outer layers a house can have on the roof. After determining how many layers you have on your roof and if you are repairing the roof, research how to fix that particular problem. Do not let any roofing problem continue or you will experience more serious damage and the costs of repair will escalate. Once you have located the problem in your roof, check for wood rot, repair, and proceed with re-roofing.

Building a new roof will require determining the type of finish roofing material you want. If you are doing asphalt shingles, determine the number of bundles you will need, enlist the help of friends and neighbors and go to work hammering the shingles to the builders’ felt and plywood sheeting. If you are using other types of roofing materials like slates, metals, woods, or ceramics unless you are a professional roofer, you will need expert advice and help. When estimating the cost of you new or repaired roof, do make sure you include labor and tax.

What types of Roofing Materials Should you Use?

There are many roofing materials on the market, but not every material should be considered for every roof. A low sloping or flat roof may require a surface much different from roof with a steep pitch. Slate and tiles are very heavy so the structure of the home must be strong enough to handle these materials. Consider all the options to be able to choose the best options for your home.

Materials

• Asphalt shingles are the most commonly used shingle materials. Asphalt shingles are the least expensive and require little skill to install. They are made from fiberglass materials that have been impregnated with asphalt and have a surface of sandy granules. The standard single thickness is one the one used on most homes and thicker laminated produces are also available. Laminated shingles are appealing in texture and last longer than regular asphalt shingles. They are fairly expensive.
• Wood shingles was the basic choice of shingles for centuries and is still a viable option though in some areas fire codes prevent wood singles. Usually wood shingles are made of cedar, southern pine, or redwood. They are sawn or spilt and placed in patterns on a roof. They last about twenty-five years, but do cost more than twice as much as asphalt shingles.
• Metal shingles are made from copper, aluminum, steel, copper-and-asphalt, and lead. All are highly durable but very expensive. Lead and copper or copper/asphalt is installed in a shingle pattern, but other types are used for seamed roofs involving vertical lengths and linked with solder. These types of roofing materials start at $250 per square foot, but usually cost much more than that.
• Tile and cement roofing materials are customary on Spanish and Mission style homes and there are metal roofs that can replicate tile’s undulating effect. These are extremely expensive but are durable and heavy clay materials.
• Slate is the most durable of all roofing materials. Slate quality varies from manufacture to manufacturer but the best will endure longer than the clasps that actually hold slate in place. Slate is a hundred years old is often reused. Typically prices for a slate roof begin at $800 per square foot. Slate is also extremely heavy. 

When trying to determine what type of roofing materials you need, the existing roof of your home will be the major factor in determining the roofing you will be able to use. If you want to consider different options you need to consider the cost, color, weight, texture and durability. You may also want to see what is commonly used in your neighborhood.

Do keep in mind that you will also need building felt or tar paper before working with shingles, and if working with cedar, spans of furring strips will be placed across the roof. This will allow the roof to breathe. In snowy and cold areas, snow and ice shield membranes may also be laid. Keep in mind the time you will be living in your house. If you plan to sell quickly, a very expensive roof is not practical.

Roofing Materials - Terminology

Roofers generally don’t talk in terms of square feet, but rather in squares. The square is a rudimentary unit of measurement. One square is 100 square feet in range or equals 10 feet by 10 feet in dimension.  The roof of a typical house is usually 1,500 square feet or fifteen squares. 

Flashing is a part of repairing and putting on a new roof. Flashing is put on in strips to areas where different materials join together. An example is the juncture of a masonry chimney and the shingles or wherever the siding comes up to the roof line. Flashing will keep your home watertight if used were leakage is like to occur.

Shingles are the roof covering that consists of individual overlapping pieces. These pieces are usually flat rectangular shapes that are laid out in rows from the bottom edge of the roof to the peak. Each row overlaps the joins below. The roof point may have a cap comprising of copper or lead sheeting, but more than likely you will have a layer of shingles with a plastic layer underneath. Shingles are made from wood, asbestos-cement, ceramic or composite as well as slate and stone.
