The roof is by far one of the most important parts of your house when it comes to protecting the rest of the building and it?s occupants from extreme weather conditions and many roofs are in a state of disrepair. Yet, despite this, they are left to worsen before people are willing to act and either pay for decent repairs or bite the bullet and have a new roof fitted. Paying for patched repairs or doing them yourself, when you don?t really know what you are doing, may prove cheaper in the short term but it won?t be long before you have to patch up the holes on a very regular basis. One of the most effective ways to lengthen the lifespan of any roof is with regular maintenance and checks conducted by a professional. The life of your roof. Knowing how long to install a new roof really is a question of knowing how well looked after your current roof is. Many new roofs come with a life of up to 20 years and some more durable and hard wearing roofs will have a life as long as 40 or 50 years but if you don?t care for your roof and regularly have it checked and maintained you face a very real risk of substantially decreasing this lifespan. When you have a new roof fitted you should, as far as possible, pay as much as you can afford to ensure that you get as long a life as possible with your new roof. Taking the plunge. Having a new roof fitted will mean a fairly major upheaval in your life. It may be necessary for you to move out while it is being done so it is important to know exactly how long to install a new roof will take. Unfortunately, the answer isn?t that straight forward. Everything depends on the size of the roof, the shape of the roof and exactly what you are having fitted. Applying a single layer of shingles on an existing roof is unlikely to take longer than a few days but having your existing roof completely removed and an entirely new one built can take a number of weeks. To get an accurate idea you should get a quote from a professional roofing contractor and ensure that this information will be included. Do be aware that things can go wrong and even when there is nothing wrong with the roof a sudden change in the weather can set the construction of your new roof back dramatically. Start as you mean to go on. Once you have your new roof fitted you shouldn?t just assume that because it comes with a ten-year warranty you won?t need to do anything about maintenance for the first ten years. You should, wherever possible, have an annual check up just to make sure that everything is ok because if a small problem is found it can be fixed before the small problem grows into a much larger and more costly problem.
