In some cases, it's better to add another layer to the flat roof, but not always. As a rule, it's best to remove and change it, since no one can tell what the condition is under the felt after 20 years. However, with that said, you can superimpose a new roof on top of an existing supposed sound, felt. To do this, you will have to scrape all the semolina from the upper felt and apply a good layer of betchamin (a lower layer) and then burn the felt.
The industry sets special specifications when roofing, so make sure you can trust that your rower will do the job properly. In general, it's best to tear off the old roof, but in many cases a cover is a very acceptable option. In fact, in my experience, the vast majority of single-layer flat roofs receive modernization treatment. As we said, it is possible to frame a new roof over an existing roof, but there are certain preconditions that your roof must meet in order to be a candidate for roofing.
For example, the underlying structures and the cladding must be in excellent condition, the tiles must not be missing or cause leaks, and they must not be curved, since the installation of a new layer of shingles over the existing one is only possible if the first layer is completely flat and level. There are many good reasons to choose a TPO roofing system over an existing flat roof. On the one hand, TPO is a very durable and resistant material that can withstand damage from the elements. This makes it ideal for covering roofs in challenging environments, such as coastal areas, where exposure to wind, sun and precipitation can quickly affect common roof coverings.
In addition, TPO ceilings are resistant to moisture and temperature fluctuations, meaning they can withstand even the harshest weather conditions. Finally, because they are made of thermoplastic synthetic materials, TPO roofs are not prone to losing their structure or strength over time. Overall, investing in a TPO roofing system is a smart choice for anyone looking to protect their property against damage caused by weather and other environmental factors. Most roofing materials have a lifespan of about 20 years.
However, TPO ceilings usually last 30 years or more. This is because TPO is a very durable material that is resistant to both UV radiation and extreme temperatures. In addition, TPO roofs are also less likely to leak or other damage. As a result, they require much less maintenance than most other types of roofs.
For all these reasons, TPO roofing is an excellent choice for any building that needs a durable, low-maintenance cover. John and the guys from Fortified Roofing Brick just did my roof, great job and easy to deal with.

When you're not trying to teach others about spray foam roofs and silicone roof coverings, you can find it on the basketball court or on the golf course. Retroching is not the same as replacing a roof, and there are certain conditions your roof must meet to be a viable candidate for roofing. Roof cladding can last up to 15 years if the required conditions are met, such as a good roof structure that is not too old, and if the installation of the cladding is done correctly. A professional and honest roofing contractor should always warn you if your roof is not a good candidate for a roof or a new roof.
In addition, unlike other roofing materials such as asphalt shingles or concrete shingles, TPO roofs are extremely durable and require minimal maintenance over time. Cutting through all of this information brings us back to our original question: Can you put a new flat roof over an old flat roof? The answer is yes - but with certain conditions in place first. It's important that your existing flat roof meets certain criteria before you can install a new TPO membrane over it; these criteria include having an appropriate structural platform underneath as support as well as ensuring that all underlying structures and cladding are in excellent condition with no missing tiles or leaks present. There may come a time when you want or need to replace your existing flat roof; this could be due to wanting a different design or color or simply because you're renovating your home and want your new style reflected in your roof too! Fortunately it is possible to place a TPO membrane over an existing flat roof as long as there is suitable structural support underneath; this can save you money by avoiding having to tear off and dispose of your old flat roof which can be expensive! As you can see there are several reasons why you might consider installing TPO over an existing flat roof; these roofs can be expensive to tear off and dispose of so for years roofers have been covering them with insulating “recovery” panels and single-layer roofing systems such as TPO, E membrane; renovating roofs can also be done when you simply want or need a change to the roof; you may want a different design or color or you may be completely renovating your home to make the roof fit your new style.
