How Have Shingles Improved in the Last 50 Years?

shinglesShingles look much the same as they did 50 years ago, but the ones installed by a roofing company today will likely have some important differences that make them safer and longer-lasting than they used to be. One of these differences is in the backing, or mat, the visible aspect is attached to. Other differences include how many tabs they have, how much asphalt they include, and cosmetic differences like color selection.

The old shingles roofers used were made mostly of organic material and had a felt mat for a backing. This natural material isn’t a good thing when it comes to roofing because it can decay if it gets wet, and it can also burn more easily than a non-organic substance. For this reason, about 90 percent of the shingles installed today have a fiberglass mat instead of an organic one. While there were a few issues with fiberglass shingles when they were first developed, the kinks have now been worked out, and they are currently the superior option.

One of the things that makes fiberglass-backed shingles superior is that this material does not rot so you can leave it in storage in Winnipeg for as long as you want. It’s also far more fireproof than felt, and shingles made with this material typically earn a Class A fire rating. In terms of fire resistance, Class A means they can resist a severe fire. While this won’t keep the rest of the house from burning, it will ensure the shingles don’t become part of the problem.

The number of tabs on shingles has also changed in some cases. Typical shingles have three tabs. Once installed, this makes the roof look as though it is made with three times the number of shingles than it actually is. By varying the number of tabs, different visual effects can be produced.
Visible improvements in shingles generally take the form of expanded color palettes that allow homeowners to choose options that provide designer looks. Another type of improvement is the development of extra-reflective shingle colors. Such reflectiveness allows the roof to reflect the sun’s light and heat back into the sky, and this is a prized feature in hot areas like the Southern United States.

These are just some of the improvements that have been made in shingle technology over the last several decades. Ask your roofing company about all the ways new shingles can benefit your home.

Guidelines for Repairing, Altering or Installing a New Roof

The first line of defense for all structures is the roof. It provides protection from the elements of nature if correctly installed. There are a variety of functional and aesthetic considerations necessary when repairing, altering or installing a new roof. Because of this, it is advised that one consult a qualified architect, and roofing company.

The pitch of the roof dictates the type of materials that must be used. A roof that has a flat to low pitched roof may rely on the use of a continuous surface to prevent moisture penetration. Roofs that display a moderate to steep pitch can effectively use slate, wood shingles, metal shingles and asphalt shingles.
Following the culmination of the Civil War, sheet metal became a popular roofing option. This type of roof provides owners with a roof lasting over 100 years when properly installed and well maintained. However, changing temperatures can cause expansion and contraction of this type of roof leading to warping. Another consideration is that some types of metal lend themselves to corrosion.

A slate roof can last up to 125 years. This material is very popular in Victorian architecture offering a large variety of colors and shapes. Slate provides a durable, fire resistant surface. The down side of this version is the loosening or corrosion of fasteners and split or cracked slate. While minor repairs can successfully be made, it is advised that if more than 20% of the roof is damaged one needs to consider replacing the entire roof. Today fiberglass asphalt shingles can be manufactured to mimic slate.

Asphalt shingles have become a popular and relatively inexpensive roofing material. Originally constructed of asphalt soaked felts, today they can also be manufactured using fiberglass. One can expect a life of 20-25 years when opting for asphalt shingles. The downside of this type of material over time includes curling, becoming brittle, or being displaced by wind or snow. While these are easier to install, it is still recommended one rely on the expertise of a professional roofer.

Roofing lends itself to many dangers. A reputable roofing company will provide experienced, reliable roofers to install an efficient defense against the various elements. A competent roofer will not only offer suggestions for the most appropriate material to use, he/she will also verify the condition of the substrate prior to repairing or installing a roof.

Get The Most Protection With Scheduled Maintenance From Your Local Roofing Company

Unfortunately, when it comes to insurance, depending on your policy, you may need to meet certain obligations before you can file a claim. Specifically, when it comes to your roof, you may have to have periodic maintenance checks to confirm that a significant problem is not developing. Sometimes something that has started as a small problem can amount to a big job if not caught early enough. That is why it is important to develop a routine inspection checklist for a professional roofing company to go over and keep your insurance policy intact.

What’s more, if you make an annual inspection of your roof, you may save more than your insurance policy. Your roof covers approximately 60% to 70% of the exterior of a home. There are many aspects to consider than protection over your head. A leak in the roofing system can obviously cause a lot of damage to the inside of a home, but have you considered the prices you are paying in energy when there is not enough insulation?

A significant amount of energy can be wasted in the home if the roof is not adequately insulated or ventilated. Also, by not having enough insulation or ventilation means that your roof is not as protected against the sun’s harmful rays in the summer and cold weather conditions in the winter. A significant amount of warping, curling, cracking of the shingles can occur without the proper systems in place under the shingles. When this happens you also risk increasing the moisture in the home which again, increases the energy costs in order to keep a moderate temperature in the home.

Check with local roofers in your area to determine if they have policies or contracts in place in which your roof will be inspected on a routine basis. Most maintenance calls are performed on a yearly basis but this could change depending on where you live and the typical weather conditions you face. This way, you don’t have to worry about scheduling and your insurance policy does not lapse. As long as you have done what is required with maintenance and upkeep, any roof damage should be covered.
