HOW MANY NAILS PER SHINGLE?

It depends on the number of tabs.

For example the normal three – tab rectangular asphalt shingles used in USA / Canada need 4 nails: two above the cutouts and two near the edges.

In Europe, mostly four-tab asphalt shingles are used and the number of nails needed is 5/shingles.

More nails are needed:

- in windy regions

- when slopes are very steep, normally bigger than 200%.

In this case two nails are used above the cutout. So 6 nails will be needed for the 3-tab shingles and 8 nails for the 4-tab shingles.

WHAT ABOUT STAPLING ?

Stapling is not recommended in Europe and as far as I know also in USA and in Canada.

Stapling can easily damage shingles.

WHERE EXACTLY TO PLACE THE NAILS?

In Europe we place the nails a little above the sealant strip. The nails are placed 2-3cm above the upper point of the cutout. The nails near the edges should not be closer than 2,5cm from the edges.

On no occasion should the nails be driven into discontinuities and problematic points of the substrate.

HAND NAILING OR PNEUMATIC NAILER?

Hand nailing is more accurate. It does a better job but it is slower and most expensive. If you cannot afford hand nailing for the whole project, at least use it:

- near the rakes

- for the first course at the eaves

- for the ridge and the hips

- for the valleys.

Because hand nailing is more accurate, it will reduce the possibility of wind uplift at this critical regions.

The nails should be driven vertically and flush with the upper side of the asphalt shingle securing it in its position.

If the nail is overdriven, it will harm the integrity of the asphalt shingle.

If the nails are underdriven, they cannot fix / secure the asphalt shingles properly.

In the case that the nails are not completely vertical, they will harm the shingle with their heads. These nails should be discarded and replaced.

CONCLUSION

Learn the right nailing techniques because they are critical for the expected life and behaviour of the shingles.

Do pay to buy the best quality nails in the market.

If I had to vote for the most important accessory of asphalt shingles, nails would be hands down by preferred choice.

Nails keep the asphalt shingles in their place for many years. They protect them against wind uplift in windy and coastal regions.

Consequently, I would harness my frugal instinct at the time of buying roofing nails.

QUALITY OF NAILS

The best option is hot dipped galvanized nails (dipped in a hot zinc bath). Thus, a zinc oxide coating is formed on the metal surface which works as a sacrificial anode.

Electroplated galvanized nails are generally not recommended to be used with asphalt shingles.

GEOMETRICAL CHARACTERISTICS

Shank diameter:

It should be round 3mm. Barbed shanks are preferable.

Shank length:

It will depend on several factors:

- the existing norms

- the type (thickness) of shingles

- if the project is about new roofing or reroofing over all asphalt shingles

- number of shingle layers

- if nailing is near the ridge area etc.

- the type of the substrate.

Generally in U.S.A. the minimum recommended penetration length is 19mm whereas in Europe the recommendation is more flexible.

The massive quantity of nails used in Europe are 20mm long (25mm for ridges) which means that penetration is normally less than 15mm.

In case that the underside of the deck is visible e.g. in kiosks or pavilions, the manufacturer should be consulted for the idoneous solution.

Nailhead diameter:

This is very critical parameter with regard to wind uplift resistance. A minimum diameter around 9-10mm is recommended.

Asphalt roofing shingles are one of the most standard options for roofing materials. As a matter of fact, a minimum of 75% of the houses in the US utilize asphalt shingles. Asphalt roofing shingles are available in several styles and costs and come with warranties from 20-40 years.

You will find 2 types of asphalt shingle construction: Fiberglass mat based shingles and Organic mat based shingles.

Fiberglass based shingles are usually thinner and lighter in weight, as their backing is built from a fiberglass mat. As a result, fiberglass mat based roofing shingles are much easier to pick up making a roofer’s job simpler while carrying shingles up a ladder. Fiberglass mat shingles are also more fire retardant and usually have slightly longer warranties than organic based roofing shingles.

Organic based shingles tend to be heavier and are known to be much more rugged as their mat backing is built out of felt paper and asphalt. They’re heavier due to the fact that there’s basically a lot more asphalt utilized in them than a Fiberglass mat shingle. Organic mat based roofing shingles are also known to be much more flexible than fiberglass shingles, on the other hand they’re considered more water absorbent and might warp in time.

Fiberglass asphalt based roofing shingles used on your residence must be compliant with ASTM D-3462 standards, and Organic based shingles utilized on your property must be compliant with ASTM D-225. A large number of cities are requiring shingles to fulfill such criteria, so you need to check with your local Calgary roofing contractor and read the label on the shingles ahead of purchasing them. Fiberglass and Organic mat based shingles are comparably priced. They might range anywhere from to per square.

3-Tab roofing shingles have existed for a very long time and are still one of the most common shingle installed, however an increasing number of home owners are shifting towards architectural shingles. Architectural shingles are a little more costly but are in reality simpler to install, as less care is required in ensuring straight lines. Architectural roofing shingles typically also have longer warranty periods. 3-Tab shingles generally require a lot of skill and longer installment time because the Calgary roofing contractor needs to ensure that wavy shingle lines aren’t produced while installing the shingles. Architectural shingles, on the other hand, are a little easier to install as the lines and shadows are created to be a lot more intricate. As a result, flaws in the set up procedure of architectural shingles could be more difficult to see. Architectural shingles usually cost more than 3-Tab shingles, but their fee could possibly be to some degree mitigated by a lower installation cost.

Whichever shingles you decide to utilize, ensure that you read the shingle packaging labels and check with your local roofing company inspector first. Your home’s roofing system is one of the most essential elements of your home. An incorrectly installed shingle job or the installation of the wrong roofing shingles can lead to costly water damage and high repair expenses.

Green Roofing Materials

Living Under Green Roofs
by Roof101 – Green roofs have many meaning in the world of roofing materials, which we will try to set straight in the following. When talking about green roof systems, the meaning is, most often, a vegetation-covered roof planted over appropriate turf. Roof systems that are merely painted green, naturally, are not included by the term green roof. Some refer to roofs with plants and pots to be green roofs, although, as the description of green roofs will show you, this is not really the case. Additionally, green roofs may refer to eco friendly or solar panel roofs.

Advantages of Green Roofs
Green roofs provide homeowners an alternative to a garden, if there is one or to go along with it. The green roof provides all that a garden (or a patio) might, including a place to grow flowers, fruits and vegetables. With these growing on the roof, water will not spill as much, but rather be used for gardening purposes. Besides other technical advantages a green roof supplies, a biodiverse green roof can filter pollutants, reduce heat, increase wildlife and help the house function as an autonomous unit, elements that are foreign to any other roofing material but are part and parcel of a green roof.

The State of Green Roofs Today
True, green roofs are not as popular as one would expect them to be. Perhaps because the market remains immature, or the industry is not doing enough to promote the technologies that are already available. It doesn’t change the fact that they are sensible. In fact they are more common in Europe. A green roof might be the right choice for you too. Contact us and we will have our green roof consultants let you in on what it takes to tend to a green roof and what the advantages you will enjoy from such an option are.

Asphalt shingles are by far the most commonly used option for covering a residential roof. There is no doubt about it, the fact that they are relatively inexpensive and durable make them the most popular roofing option.

Asphalt shingles are basically made of either fiberglass or paper backing soaked with tar. Then by using adhesive, small granules are embedded onto backing. The process described makes the shingle waterproof and makes the shingle more resilient to wear and tear caused by weathering.

Other than pricing, another factor that makes asphalt shingles so popular is the fact that they can make a home very attractive. There are many different manufactures, each with their own color options giving the homeowner a simple and inexpensive way to greatly improve the overall curb appeal of his home.

Manufacturers of asphalt shingles all comply with standards set by the roofing industry, however the quality of the tiles may vary depending on brand. A good way to determine the quality is by closely examining the warranty offered by the maker backing the product. For the most part you will see a range of warranties anywhere from 5 to 10 years. However in some instances you can find warranties on the higher end of 20 to even 30 years. This type of guarantee will likely come from one of the top asphalt shingle producers, and you can expect the price of the shingles to reflect so accordingly.

When looking at the overall project, keep in mind that you can tell the difference between a 5 year manufacturer’s backed shingle and one which is guaranteed for 20 years. The cheaper shingle will appear flatter, may be less decorative and most importantly may have less surface granule content. You will also be much more limited when it comes to selecting color and pre-made trim options. The best option to take for the average homeowner would be to find a mid-range shingle with a decent warranty. This way you can have a very nice looking roof for a moderate price.

Asphalt shingles are easy to install, however due to the need for tools, carpentry skills, ventilation and weather considerations, roofing a house with asphalt shingles is best left to professionals. The end result of a newly shingled house is beauty at an inexpensive price. With cost and time savings considered, asphalt roof shingles are often the way to go when you are deciding on a new roof for your home.

Tim Carter, of AsktheBuilder.com, demonstrates just how easy it can be to replace a broken roof shingle.

These days, there is a big push to “go green” in every sector of society. The actions we take at home and in business strongly impact our world. This has created and fueled a comparatively recent new field in the arena of construction materials: green choices in building materials.

This means that you have lots of choices now in building materials such as insulation and roofing. These choices will actually lower your costs in living in your home or operating your business. They will also reduce your carbon footprint. This means you will be leaving the world a little better for future generations.

The options available in green roofing construction are varied, and they become more so with each passing day. These days, there are many green options for roof covering. There are also green alternatives to shingles and insulation. You may have put off thinking about green roofing because you think it is too expensive; however, now would be a great time to look into it.

When you think about how long roofs usually last, you may realize that green building materials will save you money in the long run. Often, the cost is actually reimbursed within just a single year of installation. Therefore, you will be able to enjoy savings on your energy bills and the fact that you are not draining the planet of energy for the rest of the life of your roof. If you are worried about the health of the earth, this is an excellent option for you.

Installation of tile roofing material is costlier than typical asphalt shingle construction, but it will last far longer. This is an effective solution since there is minimal waste as a result. Other very environmentally friendly green roofing construction options are membrane roofing and reflective shingles. Keep in mind that not just the roof covering is important in these circumstances.

The materials that go into forming the roof are significant too. Use renewable woods that are easy to find and easy to regrow. Avoid exotic, old growth woods that may be difficult to find and impossible to replace. When you build green, you leave as little impact on the Earth as possible. This reduces the amount of waste produced by using recycled materials whenever you can. To do this, you might want to salvage some roofing trusses, some recycled insulation materials, and lots of other building components. This will limit the impact that the building of your home will have on the Earth.
