Planning on layering roof shingles? Here are the pros and cons
Installing
a new roof on top of the old ones will save you time and you also won't have to
worry about spending too much on labour or even doing a whole roof replacement
project. It only involves getting rid of the damaged portion and replacing it
with a newer roof. This may seem to be a good option in the short term, but it
won't last for long. First, the damage can continue to grow and eventually
affect the whole roof which will only lead to expensive repairs in future. And
when it is time to install a new roof, you will have two layers to remove this
time and this will end up increasing the total cost of the project.
How
additional shingle can affect your roof
First,
this extra layer of shingle can decrease the life of the roof. The additional
shingles can easily trap heat that can lead to decomposing which means that you
will have to replace the roof sooner than expected. According to a survey,
layering new roof shingles can reduce the lifespan of the roof by over 40%.
Also,
most roofs can only hold one layer of shingles. So if you add another layer,
especially if it is of a higher quality than the original roof, the roof will
become heavy making it dangerous and also affecting the overall structure of
your house. This is precisely why building codes require roofs to have a
maximum of two shingle layers. Extra weight also causes issues like sagging,
trapping moisture and causing decay in the long run.
It
may affect the appearance as well
Layering
the roof shingles will indeed make the roof attractive at the beginning. But if
you do the layering on top of shingles that are extremely damaged or curled,
imperfections will appear all over the roof.
Conclusion
When
looking for a quick solution to your roofing problems, layering roof shingles
can be a short term solution but don't consider this option when you need a
long term investment. This can also decrease your home value thus reducing the
price if you plan to sell the home in future. And as a rule of thumb, always
seek advice from professional roofingTyler TX technicians before carrying out this project.
