Today’s technology has greatly improved Roofing and the materials used for a new roof. A roof 20 years ago may have lasted between 5-10 years, but with vast improvements on materials, today’s roof can last between 15-25 years; provided you contract an expert roofer with access to this new technology and high quality materials. Shingles are the most common roofing material needed and you will be surprised that instead of pebble-shedding paper matt shingles that was used 20 years ago, fiberglass shingles are now being used. Fiberglass can resist warping, come in a variety of different weights. Pebble-shedding paper matt shingles can curl and can easily come off your roof. Other types of shingles are manufactured for the different geographic conditions. Specifically, if you live in an area where you will experience harsh climate, either hot or cold, there is a shingle type for that. Just as there are shingles specifically made for strong winds and some that are hail resistant. Read more information at
Make sure you understand that you get what you pay for. Shingles are rated and given certain warranties based on their weight. The better and heavier the shingle, the better the warranty. For example, inexpensive shingles may weigh 200 lbs per 10 foot square compared to heavy shingles that weigh 420 lbs per square. With that comparison, an average warranty for these shingles ranges 20 to 50 years. If you choose an architectural grade you will be guaranteed a lifetime warranty. However, even the best shingles take some unavoidable damage from the sun, accumulated debris, and heat or humidity coming from your attic. Like the human body, just because you can’t see any damage, doesn’t mean there isn’t any. This is why you need a good roof inspection from time to time.
If you do see any damage on any shingles, it means this is a good indication that the roof may need to be replaced. Look for damp spots in the plywood or particleboard or moisture around the attic pipes and the vents. Adequate ventilation is something that is a concern and most of the times overlooked. Most homes today are extremely energy tight. However, it does have one down side to your roof. Because of the tight energy flow, there is less air movement which can trap heat and humidity. This can cause shingles to wear out from below. If you need to replace or repair your roof, make sure you contract a certified roof specialist. There is more to the installation process than just replacing the warped shingles.
