When it comes to replacing and repairing tiles, many homeowners want to save the cost of hiring a professional roofer and attempt to do the job themselves.
It can be very dangerous to climb on your roof.
This is best left to experienced roofing contractors who are familiar with the various angles of a roof.
Also, a professional roofer will know if is worth repairing shingles or if a new roof is needed.
Most local roofers will give a free estimate regarding the cost of the job and discuss all of your options available.
All this said, if you still want to tackle the project yourself, you will need to remove each shingle or tile before replacing them with new ones.
Use a hammer pry bar and a utility knife to carefully pry the old nails and remove the shingles or tiles. Remove the first row of nails and then pry up the damaged shingle. Once removed, replace it with a new shingle.
If you find that the existing shingles are very dry or brittle, the remaining shingles may crack or tear if you try to remove them.
In these cases, it is best to hire a professional contractor who can repair and replace shingles and tiles without damaging the other remaining shingles.
If there are damaged shingles or your roof is just leaking, you may also have damage to the underlayment of the roof.
This is an additional reason why hiring an experienced roofing contractor will get the job done right the first time and reduce the amount of damage that can occur from letting this type of problem persist.
