Asphalt Shingle Manufacturing in Texas
This kind of roof material is slightly flexible, with a fiberglass backing that supports the rest of the shingle. An asphalt coating over this backing helps keep water out of the roof and supports the mineral grit that makes up the top face of the shingle. This grit comes in a wide range of colors and helps the roof avoid sun damage and shed snow. These are essential elements when it comes to roofing in Texas.

Asphalt Shingles and Texas Weather
Texas experiences two of the most damaging weather phenomena a roof can suffer: hail and high wind. These can batter and shred shingles or lift them and tear them from their nails, creating leaks in the roof’s protective surface. The Texas Department of Insurance recommends that homeowners choose only asphalt shingles that comply with ASTM D 7158 Class H or ASTM D 3161 Class F. Because asphalt shingles use a petroleum base, they can also be damaged by very hot days and cool evenings in some parts of Texas.

Shingles should always use at least number 15 underlayment and at least two layers of felt for roofs with slopes of 2:12 to 4:12. Higher slopes require only one layer, but are less common in Texas than in many northern states. Texas homeowners with flat roofs should never install asphalt shingles. To minimize shingle loss in high winds, homeowners should use 12 gauge stainless steel nails with a head of 3/8 inch in diameter. Staples are a tempting alternative, but won’t keep the shingles on the roof in a severe wind storm.

Alternatives to Asphalt Shingles for Texas Homeowners
While asphalt shingles are inexpensive, they have a relatively short lifespan when compared to many other materials. Most last only 15 to 20 years, with more replacement and maintenance required in areas of Texas with harsh weather. Once they have been removed from a roof, shingles usually cannot be recycled. They also don’t work on the flat roofs common on some commercial buildings and in some styles of Southwestern architecture.

Texas homeowners who have roofs that aren’t appropriate for asphalt shingles or who want to avoid this material’s disadvantages can choose from several different options, including metal, wood, clay and concrete. Many of these products qualify for impact-resistant roofing credits from the State of Texas itself. These credits have been designed to encourage homeowners to use roof coverings that can stand up to hail and high winds, and come in four levels.

Red cedar shakes and shingles, polymer roof tiles and fiberglass shingles are all highly impact-resistant, as is synthetic slate. Formed and coated impact-resistant steel panels are common on commercial buildings in Texas, though fewer homeowners use them. Traditional clay tiles are attractive and part of Texas heritage, making them a distinctive and fairly common roofing material in the south, but they don’t qualify as impact-resistant and can be easily damaged by hail.

Asphalt Shingle Benefits for Florida Homeowners
As in most of the United States, asphalt shingles are king when it comes to Florida roofs. These shingles are inexpensive, attractive, easy to install and come in several different colors and styles. They work on roofs with a wide variety of slopes, making them suitable for the many different types of architecture found in Florida. Asphalt shingles hold up to most weather and require relatively little maintenance. This makes them an excellent choice for vacation homes, where the owner may not be present to maintain the roof year-round.

Installation
Florida is prone to severe weather, including high winds and driving rain in hurricane conditions, that can damage or destroy asphalt shingles. The state of Florida recommends that all shingles chosen for use in that state meet either ASTM D 3462 or ASTM D 225. Homeowners should check their local wind zone to decide which shingles are best for them; Florida residents may live in High Velocity Hurricane Zones, wind zones of 110 mph or greater, or wind zones with speeds below 110 mph. In high wind zones, special shingles and extra nails are required to maintain roof integrity.

Shingles for high wind conditions should have the Miami Dade NOA logo and/or labels indicating that they comply with FBC sections 1507.3.5 and 1507.3.7. They should be installed using 6 nails per shingle to provide the greatest protection in Florida hurricanes. This, plus use of shingles with an interlocking design, allows asphalt products to stay on the roof in good condition when other materials could blow off or become damaged. Asphalt shingle installations in windy areas of Florida may be more expensive than roofs in regions with less severe weather, but the best quality allows the roof to make it through even hurricane-level winds.

Other Roofing Options in Florida
While asphalt shingles are the most popular option for Florida residents, they’re not the only kind of roof covering in use. Sheet metal roofs, both coated and uncoated, are common on commercial buildings. Some residential buildings also use this type of roofing, as well as copper or steel shingles. Metal is more wind-resistant than asphalt, but also more expensive and less insulative.

Some Florida homeowners also choose roof tiles. These may be made of ceramic or concrete material and tend to be very heavy. They’re common on traditional Spanish-style structures, but don’t qualify for government discounts that favor roof materials that resist hurricanes. Roof tiles can blow off or be broken by high winds. When a roof loses its tiles, they often damage nearby cars, buildings and other structures. That means that asphalt shingles, despite their less charming appearance, are often considered a more desirable roofing material in Florida.

Structure
This popular roofing material is made up of a fiberglass base material that provides strength. Over this, manufacturers lay a thin layer of sticky asphalt, similar to that used on roads. The asphalt is used to hold a granular coating made of crushed minerals. This coating helps repel water and protects the roof from the sun. It can be dyed to produce a wide range of shingle colors.

Most homes in New Jersey still use roofs with a relatively steep slope that discourages buildup of water and snow. These roofs work well with asphalt shingles, which require a pitch of at least 4:12 and can be installed on roofs with a pitch of up to 12:12. On low slope roofs as low as 2:12, asphalt shingles require significant extra waterproofing and ventilation to prevent leaks and other performance problems.

Types of Asphalt Shingles in New Jersey
New Jersey roofers use several different types of asphalt shingles on homes and businesses. The most common and least expensive is the strip shingle. This shingle is rectangular and has several cut-out tabs. It is nailed directly to the roof sheathing, with each course overlapping the previous one.

Roofers may also use dimensional, or laminated, strip shingles. These are thicker and provide the illusion of depth. Laminated shingles look more like traditional slate and are much more expensive than strip shingles. In very windy parts of New Jersey, it’s often smarter to use interlocking shingles, which are less likely to blow off of the roof during a storm. These mechanically attach to one another instead of using a sealing strip.

Disadvantages of Asphalt Roofing in New Jersey
Despite the fact that asphalt shingles are among the most common New Jersey roofing materials, they have some disadvantages for use in this state. For instance, this type of roof covering can decay rapidly when exposed to sudden weather changes. The climate in New Jersey is much less consistent than the climate in many other states. Sudden storms and changes in temperature and humidity are common, as are the famous winter and spring “nor’easters.”

This means that New Jersey homeowners who choose shingles may have to replace their asphalt shingles more frequently than those in areas with a more moderate climate. As asphalt shingles are non-recyclable, they end up contributing heavily to the waste stream.

Alternate Roofing Options for NJ Homeowners
While they’re the most popular option for New Jersey homeowners, asphalt shingles are not the only roofing material used in this state. Other options include steel, aluminum or copper sheeting, which is used heavily in commercial buildings, as well as clay, concrete and slate tiles, which last for a long time but are heavy and much more expensive than other options.

1. Fire Resistance
Terra Cotta is one of the few materials used for roofing that offers resistance to fire. This is a huge advantage over a number of different materials for several reasons. If the building includes a fireplace there is always the chance that any flying ashes or coals can cause the roof to be lit ablaze. If the home is near a lot of trees, happens to be in a populated area, and/or is near a lot of power lines, it can be more susceptible to accidental fires than homes in other areas. Having a Terra Cotta roof in place will prevent the roof from catching fire. This is most likely the number one draw to having a Terra Cotta roof in Southern California. Forest fires break out all the time in southern California, in fact, the state is notorious for it. The last thing they need is a building accidentally catching fire and spreading. Having Terra Cotta roofs in place keeps the fire from spreading rapidly in a populated area. And there are a lot of populated areas in Southern California. Los Angeles alone has over ten million inhabitants. That’s a lot of power lines and homes congested together.

2. Insulation
Because roof tiles made out of Terra Cotta are much more dense, they help provide more insulation than any other type of roof. They help reflect the sun’s heat, keeping the home cooler. This is a huge advantage in the southern California climate, where temperatures rarely drop below fifty. And it keeps the home warm during the winter as well. This has a great affect on energy savings too, helping to keep energy bills low.

3. Long Lasting
Terra Cotta roof shingles have a tendency to last much longer than any other roofing material, up to two to three times as long in some cases. Although a little pricier than the average roof, Terra Cotta roofs may not have to be replaced for an entire life span.

4. Durability
Terra Cotta roofing holds up well in all weather conditions, as well as being resistant to insects and birds. Because of this, it requires much fewer repairs than most other roofs, and most of the time the only repair required is the replacement of a broken shingle.

5. Environmentally Friendly
Terra Cotta roofs are made out of clay, which is a natural resource that will not run out any time soon, and the process of making Terra Cotta shingles has little effect on the environment. Because they last so long, replacements do not have to be made often, resulting in less wasted material.

These are five reasons that Terra Cotta shingles are becoming more and more popular, especially in Southern California, where they have an even more positive effect.

Flat roofs are becoming more popular for both homeowners and business owners because of the benefits they offer. The first benefit is that it is safer to climb onto and work on than sloped roofs. Flat roofs are not entirely flat, in fact they purposely have a slight slope to them to help drain off water and snow, but they are much easier to stand on than roofs with dramatic slopes. This allows you to make repairs or maintenance more easily and safely than on a sloped roof.

Flat roofs may seem to have a big disadvantage with areas that get a lot of snow. Sloped roofs are supposed to have the advantage over flat roofs because they allow for so much run off, right? It’s true that flat roofs do not allow for as much run off as sloped roofs and can accumulate a lot of snow over time. However, flat roofs allow you to easily and safely climb onto the roof to remove the snow. It also eliminates the need for roof rakes or hiring people to help you clean off your roof.

Flat roofs also allow you to turn your roof into your own personal area. As long as it’s done properly, a flat roof can accommodate for gardens, a spot for sunbathing and more. A flat roof can also be a great spot to install solar panels as it can absorb sunlight throughout most of the day if it’s in an open area. Solar panels installed on sloped roofs do not have such a large window of time to collect sunlight because they’re usually facing one direction.

Whether the building is being used as a home or a place of business, a flat roof can give you many benefits that a sloped roof can’t provide.

Is your ceiling bulging or sporting ugly stains? Is water dripping onto your floor? It’s easy to know when you have a leak, but locating the source of the problem might be a bit more difficult. Once you’ve ruled out a leaking toilet or overflowing bathtub, it’s time to suspect your roof.

Head up to the attic or crawl space, position yourself in the general vicinity of the problem area and look for a wet spot in the roof. Although the leak itself is probably not in that exact location, the most likely culprit is the flashing closest to the problem area.

Flashing is made of aluminum or galvanized steel, and its purpose is to cover certain construction areas to keep them from leaking. On the roof, you will ordinarily find it in such areas as the valleys, the vents and the chimney. When flashing fails, it is normally because it has oxidized or, for some reason, come loose.

Replacement may not be necessary. You can plug pinholes with roofing cement, and holes up to ¾ inch respond well to patching. Clean the area and roughen with a wire brush, then cement into place a patch of the same material and cover with additional roofing cement.

Chimney Flashing

The chimney is a common site for roof leaks, but the flashing may not be the problem. First, check the condition of the chimney itself. A damaged chimney can allow water to run under the flashing and, from there, through the roof. If this is the case, you’ll have to repair the chimney.

If chimney repair does not solve the problem, check the chimney’s cap flashing. If it has come loose, pull it gently away from the chimney and reattach with roofing cement. If the chimney’s base flashing needs replacing, lift the surrounding shingles and cement new chimney base flashing underneath. Seal all seams with roofing cement or silicone caulk.

Head Wall Flashing

If you’ve traced the leak to where the roof butts up against a vertical wall, you could have a problem with the head wall flashing. These repairs will entail dealing with the siding material on the adjoining wall as well as with the roofing material.

Lift the surrounding siding and roofing material gently away from the structure. Cut a piece of replacement flashing larger than you think necessary, apply roofing cement and slide the flashing under the roofing and siding. Chip out any old mortar and use masonry caulk to seal any joints. Use urethane roofing cement or silicone caulk to seal the seams.

Vent Flashing

Roof leaks are often traceable to plumbing, attic, furnace or air-conditioning vents. Before replacing the flashing, remove the roof shingles that cover the flange, then pry off the old flashing and remove nails. Push a new piece of vent pipe flashing into place and nail it near the edges. Replace all shingles, and cover all nail heads with roofing cement.

Roof Valleys

When roof valley flashing fails, some of the water might not make it all the way down to the gutter. To replace, gently pry up the surrounding shingles and spread roofing cement about six inches underneath. Slide the new flashing into place under the shingles.

In General

When patching flashing, make certain that your patches are composed of the same material as that found in the original flashing. If replacement is necessary, be sure to get the right kind of flashing for the area under repair.

Fortunately, repairing roof flashing is more dangerous than difficult. If you have a fear of heights, however, it might be prudent to have your roof repaired by a qualified roofing company.

Appearance
Natural slate roofs provide an elegant beauty that no other material can match. The natural variations in the slate tile create an appealing look from a distance that makes a slate-roofed building stand out from neighboring asphalt-roofed structures. Slate roofs are an excellent choice for vintage homes, ecologically-friendly structures and historical restorations. They complement brick and stone architecture well, but can be used on just about any kind of home.

Durability
Slate is an extremely durable, long-lasting roof material that is rivaled only by tile. Roofing tiles made from this stone absorb very little water, making them excellent at deflecting rain and avoiding frost damage. The average slate roof will last 100 to 150 years with correct installation and occasional maintenance. Many slate roofs have been in place for even longer, requiring only occasional re-flashing and tile replacement.

Roofs made of slate tiles also resist fire better than asphalt or similar roofing materials. They never rot or develop mildew and they are impervious to insect infestations, unlike cedar shakes and shingles. When treated with chemical sealants, slate roofs are also resistant to efflorescence, stains and moss or lichen growth, though some homeowners see these features of the natural aging process as desirable.

Installation
Installing a new slate roof can be relatively expensive, at between $10 and $40 per square foot, or about 10 times the cost of a similar asphalt shingle roof. Slate costs 1 1/2 to 4 times more than wood shakes or shingles, 3 to 4 times more than clay or concrete tile, and 2 to 3 times more than metal roofs, including copper. Its actual cost of ownership over the course of the roof’s lifetime is far lower, however, since most other materials need to be replaced frequently. Asphalt roofs must be redone entirely every 20 to 35 years, for instance.

The actual slate tiles can be secured to the roof using one of two ways. The most common technique is nailing with copper or stainless steel into a timber batten. It’s also possible to attach the slates to the roof using special hooks, which make no holes in the slate and produce fewer weak areas. This method provides better support in areas with severe weather conditions as the wind is less likely to blow the tiles off the roof. Hook fixing also makes it easier to put slate on unusually-shaped roofs, since it allows for smaller tiles, but this technique is somewhat more expensive than nailing.

Considerations
One of the biggest drawbacks of slate roofing is its weight. This material can weigh 800 to 1,500 pounds for every 100 square feet. That means that it requires an extremely strong roof structure to support it effectively. Many modern homes must be reinforced to carry the extra weight before a new slate roof can be installed.

Another common disadvantage of slate is its relative fragility under pressure. This material can last for centuries, but breaks easily when walked on. If you install slate on your own roof, you may need to have basic maintenance performed by professionals who know how to walk on the tiles without damaging them. This can increase the difficulty and price of maintaining your slate roof.

Perhaps the most popular Maryland roofing trend right now is architectural roofing shingles, which are sometimes called laminated or dimensional shingles. They have revolutionized the roofing industry recently. Maryland home-owners have been quick to join the trend, using the architectural shingles to achieve dramatic three-dimensional appearances. Manufacturers make the shingles from a heavy fiberglass foundation and ceramic-coated mineral granules, with the combination tightly packed into water-resistant asphalt. The process produces shingles capable of mimicking the appearance of cedar, slate, or other natural products at only a fraction of the weight, meaning there’s no need for additional roof support. Yet architectural shingles are still thicker and more durable than traditional asphalt shingles, resulting in greater endurance, increased wind resistance, and longer warranties.

Architectural shingles feature random tab placements, encouraging unique, one-of-a-kind layouts that recreate a classic roofing style. Many Maryland residents favor dark green or terra cotta shades, using the shingles’ variable colors and textures to highlight distinctive roof properties like gables, turrets, and steep climbs. Architectural shingles may also come coated with copper or zinc granules to prevent algae growth, which can be a common problem in humid areas with extensive rainfall. If untreated, algae can cause black streaks to form on shingles, ruining the roof’s appearance.

Some Maryland homes have also joined the green roof trend in an effort to help the environment and to conserve energy. Often seen on high-rise buildings, green roofs utilize flowers and vegetation to lower heating costs and to cool the surrounding environment. Green roofs may either be extensive, which means they use thin layers of soil to form a lightweight roofing system, or intensive, a style featuring an abundance of lush greenery. A green roof, sometimes called an eco-roof, is essentially a rooftop garden and adds a touch of natural beauty to any structure, particularly when placed in urban environments. And aside from their charming appearance, green roofs can greatly reduce a home’s temperature in the hot summer months while also providing energy-saving insulation during harsh winters.
