The Basic Materials in Roofing

Your choice of roofing materials often depends on your locality, as much as on your own personal taste. In some regions, for example, metal roofing is a common selection due to its fire resistance, while in other regions, the predominant home styles might call for a Spanish-influenced tile tool. Roof pitch (angle) also affects the kind of roofing materials you can use. For example, wood shake shingles may be in use for steeper pitched roofs but are not suitable for flatter, low-pitched roofs.
The following are the most common choices for residential roofing:
Here is a roofing option that is high-end and highly attractive. However, it can be very heavy and expensive. Aside from this, it could be difficult to have it repaired when it gets damaged and really slippery to walk on.
Metal roofs that are made of aluminum or steel became popular in the recent years because they are fireproof and highly durable. It needs specialty contractors to install them which is why they are expensive. However, these can be cost-effective in the long run because of their long life. Available now are several kinds of metal roofing systems which include the products that imitate the appearance of composite shingles and raised-seam panels.
Wood Shingles or Shakes
Here are attractive but pricey shingles that offer wonderful durability. However, these may not be the best choice for places that has a high probability of experiencing fire.
Asphalt Composition Shingles
These type of shingles are easily obtainable and cheap. However, the may appear less attractive compared to the other options because they appear flat. However, this is the type of roofing material that is most popular.
Second Layer or Tear Off?
Laying a new shingle roof became common over the preexisting layer. However, there are jurisdictions wherein this is no longer allowed. It is now required to tear-off the previous roofing. Even in places that allows layering, it is important to carefully consider the application of the new layer of shingles over the old because of the pros and cons:
Reduction of Waste and Work
Layering has the primary advantage of minimizing the involved work. Whenever you strip off the existing layer and lay down a new one, more work is added to the process. It may not be a real problem whenever roofing professionals tackle the job as they can strip most of the roofs during daytime. However, if you’re the one who is doing the job on your own, putting the new roof over the old roof is recommended.
It is not recommended to lay added layers of asphalt shingles because the roofing materials may become to heavy for the roof framing that lies underneath. When it comes to older houses, it may become a structural problem. Slate shingles are made of materials that are exceedingly heavy and a single layer of it may be equal to triple layers of asphalt shingles.
There is another problem when it comes to shingling over the existing shingles as you may essentially repeat certain surface irregularities that could already be present. Whenever you are contemplating on the installation of a new roof, it is highly likely that there are waves, bumps, and bubbles that needs remedies. Whenever you put the new shingles over any of the existing problems, you may end up having a rather unattractive roof. A way that can help minimize this problem is by going over the old roof and correcting every problem that you can before having it re-roofed. It may not take much more than a hammer as there are a handful of shingles and some roofing nails that can correct protruding nails, bumps, and gaps.
Considerations in Cost

It may range from the cheap three-tab asphalt shingles up to slate or architectural shingles. Whatever roofing contractor you choose, the cost will get affected by the roof’s square footage, steepness, as well as other factors. The three-tab composite roof for any small home may only cost $7,000. Roofs that use architectural asphalt shingles may cost somewhere from $3.50 to $5.50 for every square foot. This cost includes permit fees, demolition, cleanup, and waste disposal.

Consider Roofing Work During the Off-Season
It can be amazing to watch a well-coordinated roofing team which is why they are paid to do the roofs. In a lot of place in the USA, late spring to early fall is the best roofing season as there are skilled crews who can extend their work season even when there are snow flurries that could be threatening. Because of this, you need to hire skilled personnel to roof your home whenever it is the off-season period. During this time, you may enjoy lower prices because of the low demand in labor. Whenever it is off-season, the trick to get the roof job shoehorned is to have a big team of professional roofers who can complete the work in hours, instead of weeks or days, so you can take advantage of the dry period.
Understand the Process of Roofing
You may eventually create advised decisions if you understand the jargon used in the trade and understand the process whenever you need to hire a roofing crew.
It may only take three to four days to finish the installation of a professional and moderately-sized roofing job. Overall, roofing crew follows a process that goes like this:
- The removal of every existing shingle and deposit of these in a roll-off dumpster. Old or damaged drip edging and valley flashing may also get removed by this time. If you have a good crew, they will use the magnetic tools to pick up metal objects such as nails fro the lawn. Aside from this, they will also use protect foundation shrubs and plantings during the tear-off.
- If the roof is still in a good condition, allow minor repairs. If this cannot be completed, you may replace the bad wood with 1 x 6 sheathing boards or a new plywood sheathing whatever could be applicable to the type of roof that you have.
- In certain regions where it is required, install ice dam protection. This synthetic waterproof barrier material is designed for the prevention of melting ice from the backing up beneath the shingles and its penetration through the sheathing where the moisture could lead to severe damage.
- Over the roof sheathing, lay down the asphalt roofing. This layer of roofing paper can create an inner barrier against the water that penetrates into the house. As they progress towards the peak, rows of roofing paper gets overlapped and are often stapled or tackled in place.
- Around the edge of the roof, apply the metal drip edging that has both the gable and eave sides. Nailed in place over the ice guard or roofing paper is the metal drip edge.
- Wherever necessary apply the new valley flashing in areas where the two roof planes meet. Typically sealed with the roofing caulk and nailed to the roofing deck is the valley flashing.
- Starting from the eaves, apply the tab shingles as you work upward towards the peak. This is where roof vents get installed while the shingles progress towards the peak.
- All around the areas where the leaks may come into the house such as around stack vents, skylights, or against the chimney, apply the flashing. You may install the flashing as a part of the installation of the roofing. It may occur as rows of shingles that progress upwards on the roof deck.
- Have the ridge vent installed. It is a continuous vent found along the roof’s peak that can help in the circulation of air in the attic space. This can be integral in the prevention of winter ice dams and the exhaustion of hot air. It is possible for ridge vents to not get included on older roofs but it would be a great idea to install them whenever the house gets re-roofed. Whenever it is not practical to install ridge vents, you need to install other types of gable or roof vents so that the attic space will have ample air circulation.
- Have the hauling of debris and final cleanup completed. Check if the installation has been inspected and approved by the building inspector.
