Why You Should Replace Rather than Roof Over Your Existing Roof

If you’ve been in the market for a new roof for your home, you have probably run across the option of roofing over top of your existing roof.

“Roofing over” is a method that leaves the current shingles and roof deck in place, and installs new shingles right over top of the existing ones. Alternatively, reroofing requires removing all existing shingles, doing any necessary repairs or replacement of the roof deck, membrane, and supporting structures beneath, before replacing the shingles with new ones.

Roofing over your roof requires that all the existing shingles are perfectly flat without any curling, that your roof deck be in perfect condition, that there are no leaks or ventilation issues that need addressing, and that the current roofing structure is able to withstand the additional weight of a second layer of shingles. However, if all of these things are true, you may not need a new roof at all. And even if those conditions are in place, a roof over existing roof can appear wavy and uneven. In most cases, a roof over does not make long term sense for homeowners, which is why we do not recommend this to our clients and do not guarantee this type of work.

We should note here that it is possible to roof over certain materials, like membranes that are in decent condition. This is done more often on commercial roofs depending on the core sample, decking, condition of insulation, etc. This type of project is only performed after careful inspection of the flat roof and an analysis and assessment of the materials and decking beneath the membrane.

Roofing over an existing roof is sold to homeowners as a cheaper alternative to replacing their roof. Often times, though, roofing over does not really solve the underlying issues the structure may have and can end up being a more costly option.  If you’re looking into replacing your roof, it’s likely because you’ve noticed leaks here and there, there’s damage to the shingles, shingles are missing or deteriorated or you’re noticing your energy bill is soaring. Putting new shingles overtop of existing ones doesn’t address any of these critical issues on the inside, which means damage may continue to occur. Putting another layer of shingles on top of existing ones that have issues also means it will take more time, money and material to get to and diagnose the problem, and more labor to repair the underlying issues.

Replacing your roof may cost more up front, but the return on investment is higher.

Over the long term, a new roof will look better, last longer, and protect your home better. When you allow a licensed roofing contractor to remove the existing shingles, they can properly assess any other repairs that need to be done to the roof decking, membrane, flashing, structural beams or ventilation systems. Having these issues addressed at that point means the overall lifespan of the roof will be longer. It’s also important to note that some roofing material manufacturers will not warranty a product that is put over existing shingles rather than onto a clean roof deck. While roofing over a roof may be cheaper upfront, the costs of uncovered warranty claims and an overall shorter lifespan don’t pan out in the long run.

Your roof is a major part of your home that you want to look good and function well. When you’re considering your roofing project, consider that your roof literally protects everything in your home beneath it. It’s not the place to cut corners. Before reroofing your home, research roofing contractors in your area, read up on their online reviews and ask around your neighborhood for recommendations. Get quotes from at least two to three reputable companies and research the materials they work with to ensure they are high quality and guaranteed with a manufacturer warranty.

Where is That Roof Leak Coming From?

If your roof is not well-maintained, there is a whole list of issues that could occur, including structural damage and unhealthy mold growth. If you have noticed water stains or actual water coming from the ceiling, you might have a leak. Immediately repairing leaks is essential to keeping your roof in the best condition, but how do you know where the leak is coming from? The following are some common problem areas you can check to find your residential roof leak.

Shingles and Other Materials

The actual shingles or other roofing materials on your roof could have damage that is allowing moisture into your home. Damaged shingles will be buckled, corroded, cracked, or missing all together. You could also look for granules on the ground surrounding your home or nails that are missing or backing out. If you have trees that hang over the roof, be sure to check those areas, as a swaying branch could easily wear out your roofing.

Flashing

The point of flashing is to guide water in another direction when it wants to seep down into a seam on the roof. Flashing is located around chimneys, vents, and other areas where there’s an intersection or an angle in the roof. When flashing is not properly installed or sealed, water will begin to flow underneath and damage your home. Look for loose flashing, ripped pieces, or missing areas.

Skylights and Chimneys

The more extra features you have on your roof, the more chances water has to get in. Skylights and chimneys can be both functional and aesthetically appealing, but without proper installation, it’s easy for water to penetrate the roofing materials surrounding them. You should have a professional look at the seams and the installation to make sure it is all sealed correctly.

How to Reduce the Risk of Fire Damage

Your roof doesn’t just finish off the look of the house. It protects you, your family, and your belongings. If your roof becomes damaged, it is not going to provide that protection. The following are some measures to take to reduce the risk of fire damage to your roof.

Use Fire-Resistant Materials

When your roof is installed, speak with the contractor about the type of roofing materials being used. If it costs a little more to get a higher-class material, it is often worth the investment. Class A roofing materials are the most fire-resistant, followed by Class B, then Class C, which are each less resistant than the one before. There are also unrated materials, which are the least resistant to fire.

Repair Holes and Gaps

Fire-resistant roofing materials will begin the job of protecting your roof against fire damage, but you should also have holes and gaps repaired. Damaged areas of the roof won’t have the same protection as other areas. Whether you’re missing some shingles or have a gap in your flashing, a fire could sneak through those damaged areas and into the less protected areas underneath.

Regularly Clean the Roof

Fire-resistant roofing materials doesn’t mean fireproof. If you have a lot of debris collected on the roof and it begins to burn for an extended period of time, the heat could eventually get to your roofing materials and ignite them. Any time debris falls on the roof, due to the change in seasons or the change in weather, be sure it gets cleaned off.
