WHAT EXACTLY IS ROOF FLASHING?

Flashing is a continuous series of thin pieces of sheet metal or other waterproof material that is installed to keep water from getting into a building from a vulnerable angle or joint.

HOW ROOF-FLASHING WORKS AND WHAT IT DOES

  • It typically operates under the principle that, in order for water to get through a joint, it must fight against gravity and work its way up.
  • In the case of hard rain that is being driven by the wind, the driving force of the heavy rain would have to be diminished.
  • Roof flashing can be installed in one of two ways. It can either be concealed or exposed on the outside of a building’s roof.

EXPOSED ROOF FLASHING

Flashing that is exposed is usually made of sheet metal. This is how flashing got its name: the metal material catches the sunlight and reflects it, creating an eye-popping, flashing effect.

The sheet metals are generally made from the following metals;

  • Aluminum
  • Copper
  • Lead or Lead-coated Copper
  • Painted Galvanized Steel Stainless steel
  • Terne metal
  • Zinc alloy

CONCEALED ROOF FLASHING

Concealed flashing is usually made of either sheet metal or a waterproofing membrane.

The waterproofing membranes are generally made from materials such as fabric made from bituminous coal or sheet material made from plastic.

Which type of membrane is used really depends on the climate and on the building’s structural requirements.

Aluminum and lead are not recommended for use as concealed flashing materials because they experience adverse chemical reactions when coming in contact with cement mortar.

Copper is one of the best metal materials to use for exterior flashing because it is durable and malleable. Using copper in any roofing project will ensure that no weak points exist in the roofing structure. As opposed to some other flashing materials, copper will not destruct if exposed for long periods to sunlight.

THE 2 MAIN TYPES OF ROOF-FLASHING

Flashing that is placed around objects that stick out from a building’s roof, like chimneys or pipes, to keep water
from pooling at joints or seams by forcing it to run off.

Roof penetration flashing is used around cables, pipes, and supports to waterproof these vulnerable areas by providing a protective barrier.

ROOF-FLASHING FOR THE HOMEOWNER

1. Brands and Services

There are many types and brands of flashing available on the market, but homeowners may have trouble deciding between all the different brands and styles.

2. DIY Flashing

Flashing is a difficult project that is essential to execute with great precision, so it is a good idea for homeowners to seek professional help rather than try to do it themselves.

3. Technicalities

The flashing has to be carefully constructed and strategically placed so that water is definitely deflected away from the roof’s trouble spots and not into the underlying structure of the roof (and the home).

4. Improper Execution

Flashing installation done by nonprofessionals can lead to all sorts of trouble for the homeowner and the home, including mold, water seepage, leaks and structural damage.

Successful roofing application requires that installers adhere to certain proper application methods. It is especially easy for inexperienced roofers and do-it-yourself homeowners to make certain roofing application mistakes simply because they are not aware of the various things that can go wrong. Here is a list of some of the most common mistakes and what can be done to avoid them, thus ensuring a successful roofing project.

Mistake: Not including the starter strip.

Problem: This does not provide the proper shingle application base.

Fix: Apply starter shingles at the rake, continuing along the eaves. The starter shingles should be cut to match the existing first course’s exposure. For new construction shingles, this means a measurement of nine inches. Three-tab repair shingles should measure five inches. Then about six inches off the length of the first shingle should be trimmed to stagger the shingles out from the first full course.

Mistake: Not ensuring that the shingles overhang at the eaves.

Problem: This could contribute to roof blow-off.

Fix: Make sure that the shingles overhang the eaves and rakes by at least one-half of an inch. There should be a spacing of about one-sixteenth of an inch between the shingles. Finish nailing three inches above the eaves, using the proper number of nails according to the geographic wind zone.

Mistake: Not properly aligning the shingles.

Problem: This is not at all aesthetically pleasing.

Fix: Vertical and horizontal shingle alignment will be required. This is best done in new shingle applications by using the chalk line. In repair application, the new shingles should be aligned with the shingles that are already in place. Horizontal chalk lines should be set every 10 inches from the bottom of the first course up. Vertical chalk lines should be set every 36 inches from the roof ridge to each shingle’s end, along the first course.

Mistake: Not properly nailing the shingles.

Problem: This could potentially lead to roof blow-off.

Fix: Follow the manufacturer’s recommendations in installing the proper number of shingles for the specific geographic wind zone. Four nails will be required in typical applications of three-tab shingles, but six nails will be required in areas where the wind velocity gets very high.

Placement of the nails is as important as the number of nails being used. Look at the manufacturer’s required placement areas to assess proper placement of the roofing nails. Drive the nails straight into the deck, never nailing from an angle if at all possible.

Know what nail length is needed before roofing application is attempted. Nails should penetrate the deck by at least three-quarters of an inch. Standard roofing nails with barbed shanks are typically 11-gauge or 12-gauge and have heads with diameters anywhere between three-eighths and seven-sixteenths of an inch.

Mistake: Using asphalt-based cements for shingle repair.

Problem: Use of incompatible materials contributes to further shingle damage.

Fix: Apply asphalt-based cement only on the underside of shingles. Damaged shingles with evidence of curling, cracking, opening, or splitting should all be replaced with brand new shingles.

This brief list represents just a few of the things that can go wrong in roofing application. Before attempting anything of this nature on their own, homeowners should consult with the professionals at United Home Experts, who can provide much needed information and advice about the best ways to repair and/or replace a roof and provide free estimates on complete roof replacement.

WHAT IS EPDM?

EPDM stands for Ethylene Propylene Diene Terpolymer.

It is a rubber membrane with a single ply that has been a major solution in the low-sloping commercial roof industry for over four decades. It is the most popular choice of architects, consultants and contractors in both new construction and replacement projects because of its value, quality, and other various benefits.

WEATHERING ABILITY

One of the major benefits of this roof type is its outstanding weathering ability. It is both waterproof and hail resistant. Because of this, it is ideal for a variety of climates, including here in the Northeast.

DURABILITY OF CONSTRUCTION

EPDM, because it is made from rubber, is also very flexible and durable. It is able to expand and contract in relation to weather changes, and this ensures that it will hold up better than other roofing solutions over time.

The unique way in which it is formulated ensures that EPDM is virtually resistant to exposure to harmful ozone and UV radiation. It also stands up well to the test of cold cracking. Because it does not rely on plasticizers to achieve flexibility, there is no potential danger of brittle membranes due to future plasticizer loss.

LONG LASTING

The lifetime costs of EPDM membranes have exceeded other popular low-slope systems, such as built-up roofing, roof_membrane_1modified bitumen, and thermoplastic that have been mechanically attached.

The durability of the EPDM membrane has also led to very long life expectancy ratings, including over 23 years in covered applications, more than 26 years in exposed applications and an estimated ultimate service life of over 50 years.

ENERGY SAVING

EPDM offers a variety of options that enhance energy efficiency to commercial roofing professionals. White EPDM membrane systems have been built with increased UV resistance in mind. These types of systems offer similar performance characteristics to the black EPDM membranes, but with even more energy and environmental benefits. It has become increasingly popular to add white coatings to black EPDM membrane surfaces to extend the life of the roof, increase energy efficiency, and decrease pollution.

EPDM roofs that are ballasted often act the same, in construction, as roof surfaces that are reflective. Although stone ballasts and pavers are not as reflective as white coatings, ongoing industry tests indicate that there is a positive impact on energy usage with this EPDM system type. During the day, the ballast absorbs at the same time as it shades the roof membrane. Then, in the evening hours, the heat is released. Some other EPDM roofing accessories include garden roof systems and photovoltaic panels, which both help to increase a structure’s energy savings.

As is the case with any roofing system, insulation is crucial to ensuring that any building is energy efficient. Adding extra insulation to an EPDM roof can not only increase the effectiveness of a building’s thermal resistance, but it can also eliminate thermal short circuits and potential moisture issues.

CONCLUSION

With so many roofing options available today, it might seem daunting to choose which one would be best for any individual project. EPDM membranes, however, stand out as the most versatile material, and they have a proven track record that reinforces why this is the best option for nearly any construction project with a sloping roof.

When it comes to the construction of a house, there are many roofing shapes and styles from which to choose  –  so many, in fact, that many people may not have the time to research all of them. Here is a quick list of 10 of the most popular and functional roof styles. We can install asphalt roof shingles on any of these styles of homes, except flat roofs, we use a different material called EPDM.

ROOF TYPES

1. ARCHED ROOF

This roofing type is most likely not going to be used for the whole building construction, as they can be costly to install, but can be used as an accent to add tremendous aesthetic value to the home.

2. BONNET ROOF

This type of roof is also not usually used on a whole house. It can mainly be found gracing the back porch or a decorative veranda. This roof type is similar to both the hip roof and the pyramid roof, which are mentioned below. The main difference is that two of the roof’s sides slope out at an angle.

3. CROSS-GABLED ROOF

This roofing type is most likely not going to be used for the whole building construction, as they can be costly to install, but can be used as an accent to add tremendous aesthetic value to the home.

 

4. FLAT ROOF

This is one of the easiest types of roof to identify because it is very common – and flat, as its name implies. Flat roofs are easier to construct than any other roof type. They are safer to stand on, and they are generally more accessible for maintenance and repairs. The main drawback to this type of roof is that it does require more maintenance than other types, largely because the lack of slope can tend to accumulate debris.

5. GAMBREL ROOF

This type of roof is very similar to the Mansard Roof. This Dutch-inspired type of roof is made up of four slopes, two on each side of the home. The lower slope is a much steeper vertical style than the upper slope, which might be visible from below, but it might not.

6. HIP ROOF

As mentioned before, this roof is very similar to the bonnet roof. The main difference is that the four sides of the roof meet at a ridge or a flat spot, instead of coming to a point at the top. This enhances the practicality of the roof type.

 

7. MANSARD ROOF

This type of roof is quite similar to the Gambrel Roof mentioned above, with a few minor differences. The main one is that the Mansard Roof does not have the vertical gable ends and the roof overhanging the facade of the home, as is the case in the Gambrel style. This French style of roof offers extra room for increased living or storage space on the top story of a house.

8. PYRAMID ROOF

True to its name, this roof type is shaped like a pyramid. This is another type of roof that is not practical to use on a whole house, but can add a beautiful decorative touch to small home sections or to corresponding outside structures like garages. angle.

9. SALTBOX ROOF

This is interesting type of roof is asymmetrical in form and features a long pitched roof with one very long side and one very short side. Oftentimes, this results in a house that is multi-storied in the sense that one side of the construction is only one story, while the other side of the building features two stories.

 

10. SKILLION ROOF

This roof type has one single sloping roof surface. It looks like one half of a triangular roof, and it can be compared to a flat roof whose roof sides have been inclined just slightly. It is not often used in full home construction but can often be seen as a special roofing option for multi-level homes

Is fishing your thing?  Then think Lake Maspenock.  In the original native language, Maspenock means “choice fishing place.”  There are more than 10 species of fish in the lake, including largemouth bass, yellow perch, white perch, bluegill and several others.  During the winter months ice fishing is allowed.

It’s the little things, like ice fishing at Lake Maspenock that make living in Upton so worthwhile.  Fortunately the homeowners of Upton believe that the town needs to look its best to maintain its quaint charm and grace.

One thing that helps the town to continue looking its best are all the new roofs which the homeowners of Upton ihave install in recent years.  Nothing makes a home – or a community – look shabby and uncared-for faster than a dilapidated roof.

Even so, the homeowners are quite choosy about the people they call a roofer in Upton.  To be considered a credible roofing contractor in this town, a contractor must meet several rather stringent requirements.

For one thing, any local roofing contractor must offer a roof with an unconditional lifetime guarantee – including labor!  Not only that, any local roofing contractor has to use only the highest grade of shingles, flashing and water-tight barriers and they have to be manufactured by Owens Corning, the recognized world leader in roofing products.  Second best simply won’t do.

But probably most important is the fact tha any local roofing contractor must have a stake in Upton’s future.  A roofer in Upton must have the best interests of the community and the homeowners at heart.  A local roofer must have roofed more than a hundred homes in this town and must have a terrific reputation locally.

That’s an awful lot to ask for.  Very few contractors can come even close to all of that.  One that does is United jHome Experts.  United Home Experts has a stake in Upton – they have roofed more than one hundred local homes and businesses and their reputation is spotless.

They also offer an unconditional lifetime guaranteed roof – including labor!  That means that any homeowner who has a UHE roof installed will never have to think about a new roof again in their lifetime.  Call UHE today and ask to speak with one of their highly-trained and very friendly roofing experts for all the particulars.

Of course, United Home Experts only uses the very best roofing products from the very best roofing products manufacturer – Owens Corning.  You don’t want inferior products on your home and neither does UHE.

That brings up one last point. Besides using only Owens Corning products on your roof, UHE also uses the very kbest, most highly-trained and skill roofing installers in the business.  They have to.  There is no other way to guarantee a roof for a lifetime.  Unfortunately, some of United Home Experts competitors don’t think your home deserves the very best when it comes to installers.  Some other roofing contractors here locally hire their installers from the back of a pick-up truck each morning at a local parking lot.  Do you want workers like that working on your home, around your family?

So what about cost?  The best cost more, right?  Not in this case.  United Home Experts roofs more homes and businesses than just about anyone else in this entire area.  That means they use a lot of roofing materials.

So much roofing material, in fact, that they demand and get the lowest wholesale price possible, allowing them to pass the savings on to Upton’s homeowners.  Check them out yourself.  Call United Home Experts and talk roofs with them.  Once you know they really are the roofing experts, then ask them about price.  You’ll be simply amazed!
