Reason not to install multiple layers of roofing shingles at Post Oak Roofing. As time passes, your home’s roof, like every other portion of your home, will wear down. If you see damage on your roof that you cannot repair, the best option is to replace it. On the other hand, installing a new roof takes time, money, and a lot of effort. Thus, you will want to make sure it is done right when it is completed.
Additionally, replacing your roof may be a remarkably chaotic process, take a week to complete, and cost a lot of money. You´ll need to employ a crew of roofers to install the new shingles. After all, you are pulling down your roof and replacing your previous layer of materials. So, make sure your roofer will build your roof correctly since you are investing a significant amount of money.
In other cases, homeowners want to keep their original shingles and simply install a new one later top of them. Although most roofing professionals do not back this practice, it is still feasible.
How many layers can be there on a roof? Will your roof be able to resist this weight? We will provide answers to questions like these below.
How Many Layers Should Have Your Roof?
There should be no more than two layers of roofing material on your roof at all. Most roofing materials are hefty and might weigh more than a ton. So, homeowners need to keep this in mind.
Are you planning to put slate tile roofing on top of other materials? You must make sure that your home´s supporting structure can handle that weight.
The average area of most roofs is 1,700 square feet. A variety of materials made up this surface, so you should estimate the weight of this structure. In this sense, you will want to ask yourself the following questions as a checklist:
• Is it necessary to improve my roof’s support?
• Does my previous layer have some damage? Is it better to fix them or not?
• Are there any signs of organic and fungal growth on the older layer?
• Is the new material set compatible with the previous layer of materials?
After inspecting your old layer of materials and verifying that no defects exist, you may begin installing your new shingles. Overlaying roofing materials may bring future problems. Thus, using this checklist will help you minimize these issues.
It Is a Bad Idea to Overlay
Because of the following reasons, it is not advisable to put roofing materials on top of one another:
• Voids Warranties
When it comes to roof repairs and upkeep, warranties are your best friend. Indeed, having your warranty revoked is the last thing you want to happen. Warranties only work under conditions that manufacturers establish. Therefore, homeowners must fulfill these specific rules. Having a valid warranty can save thousands of dollars in labor charges and replacements that otherwise, you would have to afford.
• Negatively Impacts Home Inspectors’ Reports
Are you planning to sell your house? Will you perform any necessary roof repair and improvements before selling it? Then, overlaying is not the best option for you.
By doing so, the only thing you will get is to reduce your property’s value. That is what will happen if a home inspector finds shingles stacked on top of each other on your roof. So, a finding like this will be a red flag in the home inspector’s report.
• Reduces the Lifespan of Your Roof
Finally, covering your old roof with an additional layer might generate a variety of issues. Before placing your new layer, be sure to solve your previous layer’s issues. These problems might affect your new layer as well.
For example, rotting mildew and moss from your older layer might spread to your new layer and erode the younger layer’s foundation. Likewise, it would be critical to know the condition of your roofing deck before placing the new layer. If there are problems in the wooden platform under your shingles, repairing them after overlaying will be harder and costlier.
Let’s go to the point. Homeowners only should place two layers of roofing material on top of each other, when the most.
A quick replacement procedure may save you money now. However, it may lead to additional troubles shortly. Besides, professional, and certified roofing contractors are the ideal people to inspect your roof and make sure it is in the greatest shape possible.
