The main issue facing homeowners is deciding whether it is worth it replacing the roof or will be more cost effective to get a repair done instead. This is key to managing the long term house maintenance costs with such a large job like managing the condition of the roof.
Damaged tiles and leaks can be repaired and if they only affect a small area of the roof it will most likely be better to repair the damage or in the case of a large roof, a partial roof replacement could be an option. Broken, slipped or missing tiles resulting from storm damage should be relatively cheap to put right, especially if they have been noticed very soon after the bad weather.
If ascetics are important to you, a few replaced tiles will look different and stand out on your roof against the old, worn tiles. This could affect the sale price if you are looking to sell your home as potential buyers may not want to purchase the property if they can see that the roof has undergone repairs and may need a costly roof replacement not long after they have moved in. However, this type of repair could extend the lifespan of your roof for another 10 years or more, which is highly cost effective. Roofer Derby recommends that a new roof in an attractive tile style can be a great selling point and can even add value to the house, despite the cost of the roof replacement running into the thousands.
If only part of the roof is showing signs that it is in dis-repair, it may in fact be cheaper to do a full roof replacement in the long-term. This would work out cheaper to get it all done at once, because of the costs involved in the scaffolding, workmen and equipment being needed to work on your roof. This would also mean that the roof will all match and the tiles will all be the same age, so going forward the entire roof has the same lifespan.
If your roof type is shingles, then it is possible to add a layer of shingle on top of the previous layer. This is a cheaper job, because of the lack of a need to remove the existing layer. However, if your dwelling is in an area susceptible to high wind, the new layer of shingle will not hold as well when it is nailed to the old layer. So, in these circumstances, it would probably work out more cost effective to pay the extra and have the old shingle removed. This is because the shingle holds a lot better when it is nailed directly the roof timbers.
