There are many reasons for a homeowner to redo his roof. Roofing may seem to be complicated but in reality it is not that hard. The key is to make sure that you are doing it properly and using the right materials. The first step when doing a roof is to choose the right material for your area. For example, a home that is located in an area that receives a lot of snow may choose a metal roof. A metal roof is better suited to have the snow slide off of the roof and not accumulate.
A lot of contractors may try to suggest that you keep your existing shingles on the roof. The truth of the matter is though that you should remove all of your old shingles before installing new ones. The reason why you will want to do this is because when you remove the old shingles you will be able to check the roof deck for any potential damage.
It is quite common for a roof deck to require additional repairs such as cracks, holes, or molding. With all of the old shingles removed it will be easy to determine what type of repairs are needed for your roof deck. If you leave the original shingles on the roof then you would never know if there were any repairs needed. This type of decision could cause additional damage in the future as water enters into your home.
Another important tip when doing a new roof is to remove any items around the outside of the house. As you remove the old shingles you will be throwing them off of the roof and you do not want for them to land on anything that could cause additional damage. These are just a couple of tips that will help you do a good roofing job.
