Difference Between Composite Fiberglass Shingles and Asphalt Roofing Shingles

From: www.reliableremodeler.com

Fiberglass composite shingles are actually a type of asphalt shingle.  A fiberglass shingle has an outer layer composed of an asphalt composition, and the underneath part of the shingle, which is against the roofing felt on the roof sheathing, is made of a fiberglass matting.  An asphalt shingle has the same outer layer, but the underneath matting is of an asphalt organic material.

There are a few differences between the shingles.  A bundle of fiberglass shingles is a little lighter than a bundle of asphalt shingles, which might not make a difference to you, but will to your roofing contractor, especially if he has to hand stock the roof.  Fiberglass shingles are also more fire retardant than asphalt shingles.

Asphalt shingles have a heavier look to them, as the organic matting is a little thicker than the fiberglass.  Asphalt shingles are also more flexible, which is a consideration when a roofer is installing shingles in colder weather.  They can also be a little more water absorbent than fiberglass shingles.

Fiberglass shingles are used more in the southern part of the country, while asphalt shingles are used more in the north.  Fiberglass shingles might last a little longer than asphalt shingles.  Each is a good shingle, and if you prefer fiberglass there is no reason why you couldn’t use it in the north.  I grew up north of Pittsburgh, Pennsylvania, so I know how cold the winters can get.  If you are anticipating a fall or late fall shingle replacement, you might ask your roofing contractor if he prefers asphalt roofing or fiberglass roofing.

There should be no difference in maintenance between asphalt roofing and fiberglass roofing.  Just watch for cracked or broken shingles, and get them replaced as soon as possible.  After a windstorm look to see if you have lost any shingles, especially right after the roof has been installed, and the shingles haven’t had a chance to seat themselves.  Other than that there isn’t much maintenance involved.  Fiberglass and asphalt shingles are available in warranties up to 50 years, but 25, 30, and 40 are more standard.  While they might not last quite that long, you still shouldn’t have to worry about your roofs for a long time with either product.

 

How to Find a Roof Leak

From: www.homeimprovementhelper.com

Your roof is among the most important parts of your home as it protects you, your belongings and the structure of the building from damage due to rain, wind, and more. Left untreated, a roof leak can (and will) cause damage to your home's structure as well as to your personal belongings.Therefore a roof leak should be taken seriously and repaired as quickly as possible.

Finding a roof leak may not be difficult but it can be. Are there any signs of leaking water within your home? Look around for any water spots, standing water or mold. For example, if you have a puddle on your bathroom floor, look upwards to find your source. Further, look upwards for water spots and any soft spots where the ceiling might sag. These are obvious signs of a roof leak. Also, look for simple dampness on a ceiling or wall. These can signal initial leaks that are just getting started. However, there is no guarantee that the leak is directly above where the water is dripping. Water from a leak may run down the inside of your sheating before dripping or may follow a chimney, exhaust vent, etc.. down to your ceiling.

Tracking a Roof Leak

First, inspect the roof from the inside of your attic. With luck you may be able to see clear evidence of the area that is leaking. While it is sunny outside see if you are able to see any light coming through the roof. (This will not work with wood shingle roofs as they are designed to allow light to shine through but pass water down the roof and not inside.) If it is raining outside (or with the help of some artifical rain such as a sprinkler) take a bright light source with you and see if you can follow the water trail to the source of the leak. Remember, the leak will usually be higher up the roof than the dripping water may suggest.

To investigate the exterior of your home, make use of binoculars or a ladder. From here you should be able to see roof damage and other structural problems. If your roof is wet do not attempt to walk on it. This is bad for both the roof and the roof structure. Check to make sure that water can escape from the roof's slope easily. If you see a build up of ice, you could have ice damage and once melting, this water could make its way inside your home through a damaged area.

Bad flashings are often the cause of a roof leak

Examine both your flashings and chimney area for any signs of a problem. Also, look at the points where an antenna or satellite dish connects to the home. Look for warped or cracked shingles or shakes and replace those immediately. Replace those that are too damaged completely. If you must replace just one or even several shingles, this does not mean that your entire roof will need to be replaced.

Next, look for any signs that debris may have damaged the structure of your roof. You may no longer see the debris but the damage will still be there. If you feel that you need help in identifying a roof leak, contact a reputable contractor for assistance.

 

How Can I Prepare for a Hail Disaster?

From: Allstate.com

Hailstorms are frequent occurrences across the U.S. Most hailstorms occur during either the spring or fall months, are very localized events, and don't cause extensive property damage. However, occasionally hailstones can reach about 1.5 inches in diameter. When this occurs, they can cause significant property damage to cars, windows and siding. When hailstones reach three inches in diameter, they can cause major roof damage.

Preparation Tip

Consider replacing your roof covering with roofing material that received a UL impact resistant classification (UL2218) of Class 4, meets local building code standards and requires minimal upkeep and maintenance.

Safety Tips

 

  • Listen to weather updates about hail activity.
  • Seek shelter immediately if you are caught outdoors – preferably not under a tree.
  • Stay indoors until the storm subsides.
  • Close drapes, blinds or window shades for protection from the possibility of breaking glass.
  • Park your vehicle in a garage or under a shelter.
  • If driving, pull over to the side of the road – preferably under an overpass or shelter.

 

Recovery Tips

 

  • Assess the damage to your property.
  • Check trees, shrubs and plants around your house.
  • Using binoculars, check your roof for damage.
  • Check patio covers, screens, windows and soft aluminum roofs for damage.
  • Check vehicles for dents and broken or cracked glass.
  • Cover any broken glass in your car to prevent interior damage.
  • Cover any broken windows and holes in your roof.
