Top 5 Reasons To Call A Roofing Contractor Instead Of DIY

Does your home need a new roof? Is it in need of repair? Are you considering doing it all yourself? Before you completely dismiss the idea of hiring any roofing contractors, such as Conrad Roofing Of Illinois, to do the work, here are some common mistakes that people make when they try to DIY their own roof:

Incorrectly installed moisture barrier: In between the shingles and the roof itself lies the moisture barrier. In some places, this may be called simply tar paper, even if the product is no longer made from paper. A poorly installed moisture barrier can cause rot and mold to build up in your attic, damaging not only your roof but potentially your whole house as well.

Recycled or damaged flashing: Flashing is used to keep water out of areas where there are seams, such as where the roof meets a chimney or A/C unit. It is typically made from thin sheets of metal, though you may also find vinyl flashing. One mistake that amateurs make in an attempt to save money is to leave the original flashing in place when they install a new roof. Although flashing may look fine, only professional roofing contractors will be able to determine for certain whether the flashing is in good enough shape to last another fifteen to twenty years. 

Improper nails: When replacing or repairing a roof, one common mistake is to use whatever nails are already on hand. However, you must use the correct nail for the job or risk having shingles torn off by the wind. In addition, if you do not place the nails correctly, they can be subject to corrosion. This will also eventually lead to shingle loss.

Covering old shingles: If your roof has been leaking, you may be tempted to climb up on the roof and add new shingles atop the old ones. This is an issue that many roofing contractors see, but it doesn't fix the problem. At best, it's only a temporary solution. At worst, the addition of extra singles will add more places for moisture to seep in and damage your roof. A roofing contractor will know how to carefully remove the damaged section of shingles before replacing them with entirely brand new shingles.

Improper overhang: When installing shingles yourself, you may end up not giving them enough of an overhang or you may give them too little. Having the wrong amount of overhang can lead to wind damage, as well as moisture seeping in. If you've never done any roofing before, getting the overhang just right may be difficult.
