In an earlier post, we talked about the entire GAF Roofing System and why it is important to ensure your roof is comprised of the best system in the industry. When it comes time for a complete roof replacement, be sure to understand why the roofing contractor will advise you against covering up the old roof rather than stripping it off and starting new.
Roof damage typically occurs at the most inconvenient time possible. Whether you have been avoiding repair and replacement or are hit with a hard unexpected storm, replacing your old roof can be time consuming, confusing and expensive. Because of this, some homeowners choose to have their roof recovered, rather than completely replaced. While this may appear to save time and money up front, doing so opens you up to many dangerous pitfalls that could end up complicating things even further.
Here are a few reasons why you should replace your roofing system, rather than covering it up:
Mold & Decay
One of the biggest reasons to replace, not cover up your existing roof is because of the mold and decay that could be present on or around your present roofing system. During a full roof replacement, all of the old roofing system is torn off, disposed of and then replaced with a completely new roof.
If your new roof is installed over your old roof, you not only run the risk of keeping any existing mold and decay around, but also of further promoting its growth. If there is moisture present on or under your old roof, covering it with a new layer could essentially trap the moisture. This can aid the growth of any mold and cause your roof to decay even faster, leading to expensive repairs.
Avoid Covering Hidden Damage
Whenever your roofing contractor tears off your old roof to replace it with a new one, they get a unique chance to inspect your entire roof for any damage. This includes holes, decay, insect problems and more. By taking care of this step before covering your roof with new materials, they are able to identify and solve any problems before they spiral out of control.
Choosing to cover up your existing roof can perpetuate and hide potential issues of roof integrity and damage. As a result, you are left with more pressing, expensive and extensive repairs than if you had tackled the problem from the start.
Increase the Life and Quality Of Your Roof
Naturally, allowing your roofing contractor to properly install your roof can lead to a better overall experience, including a longer lifespan for your new roof. Roofs that have been completely replaced lay more evenly on the decking of your home, are subject to less moisture issues and just look better than roofs that have been layered on top of each other.
Preserve Your Warranty
Today’s roofing materials are built to last. Depending on the manufacturer and your contractor, some roofs come with up to a 30 year warranty or more. Many manufacturers, however, will not honor their warranty if your roof has been improperly installed. Furthermore, an incorrectly installed roof could present possible insurance issues down the road if you need to make a claim. Play it safe and make sure that your contractor does a full roof replacement.
Invest in a complete roof replacement
Replacing your roof can do wonders for the look and feel of your home. In addition to its obvious purpose as your first-line of protection from the elements, your roof also has a handful of other purposes. A decorative roof can change the whole aesthetic of your home, and great-looking roofing materials are becoming more affordable each year. A high quality roof also improves the overall efficiency of your home by improving its insulation against the heat and cold.
Although we may not give too much thought to our roofs until something goes wrong, don’t forget just how important a role they play in our homes. When it comes time to replace your roof, make sure that you are working with a high quality roofing contractor that will do a full roof replacement, not a cover-up.
