If you are considering installing a brand new roof, take some time to learn some interesting and fun roofing facts that can help you make the right roofing decisions.

Take some time to read ten common roofing questions homeowners often wonder about when planning a roof installation project.

What is the most common roofing material in North America?

Roofing professionals estimate that 75% of residential homes on this continent have shingle styled roofs.

How many composition types are available with roofing shingles?

Today, the two basic types of roofing shingle composition types are fiberglass shingles or organic shingles.

Organic shingles are made from recycled layers of felt material layers with lots of ceramic granules that are embedded into the asphalt to provide more protection and an adhesive layer.

Due to this excess asphalt and protective substances, organic shingles end up being much heavier than the more commonly used fiberglass shingles.

On the other hand, fiberglass shingles have three distinctive layers that include:

  • A bottom woven mat of fiberglass
  • A second waterproof coating of asphalt
  • Then a top layer of those ceramic granules that also provide UV sun-ray protection because UV rays are known to damage roofing materials

Due to the component inclusion of a lesser amount of the weighted asphalt material in fiberglass shingles, this type of shingle is lightweight compared to the ceramic versions.

How long should a shingled styled roof last?

There are different quality grades of shingles used in roof construction that have a variety of price ranges. A less expensive shingle job could start showing signs of wear anywhere from 5 to 7 years with most shingled roofs expected to remain in good condition for at least 10 to 15 years or more.

What factors can age or wear shingled roofs?

Many determining factors can result in roof wear and tear through the years and speed up the expected roof aging process. These factors include:

  • Wearing off of top-layer granules designed to protect the roof by deflecting hot, harsh UV rays from intense sunlight
  • Weather conditions – wind storms, heavy rainfall & wintertime snowstorms with roof damaging ice buildup
  • Environmental exposure – smog, air pollution, too much humidity, not enough air moisture, or saltwater spray corrosion on oceanfront homes
  • Heavy dust or sand in the air
  • Roof damaging mold or mildew
  • Broken roofing components
  • New black or dark roof stains Rand/or water leaks
  • Temperature extremes
  • Shoddy workmanship
  • Manufacturing defect
  • Neglect of roofing maintenance tasks
  • A fire event, flood, or another emergency that impacts the roof structures
  • Not enough ventilation through the roof layers
  • Damage from heavy tree limbs or accumulated debris
  • Algae, moss or other vegetation growths on the roofing surfaces and nearby structures


Are there energy-efficient roofing shingles?

In general, shingles are the least energy-efficient among roofing types. However, more shingle manufacturers are responding to consumer demands for more energy-efficiency options. As a result, homeowners can find certain shingle model designs that have the approved energy-efficiency seal to ensure that you are getting the right product.

Can attic insulation improve indoor air temperature?

Many homeowners desire to install attic or upper-level insulation to lower their monthly energy bills and improve indoor air temperature comfort. As stated previously, roofs require a particular type of ventilation for all of the different components to work together as expected.

It is best to hire a professional to install or advise you on the proper type, amount, and location of insulation materials for the best results. It is easy for amateur handymen to inadvertently block off ventilation when installing the product.

What are the recommended shingle roofing maintenance tasks?

Most reputable roofing contractors, or the shingle company, will offer a warranty on the newly installed roof. For this warranty to be activated should roof damage ever occur, the insurance agents are likely to investigate whether the roofing maintenance tasks were done regularly.

Can a homeowner do his/her own roofing maintenance, repairs, or new roof installation?

Standing or climbing around on top of steeply sloped roofs is not a good idea unless the person has the experience and necessary skills to perform these duties safely.

Hiring a professional roofing contractor to keep up with the regular roofing system maintenance duties is often a better solution that ensures everyone’s safety and increases chances that the work will be done correctly.

How do roofing contractors determine roof installation costs?

Most seasoned roofing contractors will not quote an exact price without taking the time to inspect and assess the current roofing situation beforehand. There are a few things that roofing professionals usually figure in when determining overall costs and completion time frames.

These factors include:

  • Geographical location & climate
  • Planned roof layout
  • Size of the intended project
  • How much skilled labor the job will involve
  • Overall costs for materials, supplies & equipment used

How to choose the best shingle design that will meet your expectations.

Asphalt shingles today come in a beautiful array of attractive design options, color combinations, thicknesses, size selections, and pattern choices.

Pick the shingle style that offers the best complimentary match to your home’s existing outside exterior architectural lines and color palette.

Choose a shingle that has the extra features that you desire, like better heat deflection surface finish or greater energy-efficiency. Decide whether you want laminate shingles, 3-tab shingles, or larger form shingles.
