What You Should Know About New Roof Costs and Roofing Repair Costs

The price of roofing jobs can vary, and many people find themselves asking how much does a new one cost. The information below will help you consider essential costs, from the prices involved for roof repairs to the cost of a new roof. We will help you decide if you want to have a roofing repair or replacement.

The roof is an integral part of your property, and it’s there to protect your home from the elements. Although, those same elements can cause damage to your roof over time.

This damage then leads to you having to either repair or carry out a full replacement of your roof. You may find that you only need to have a small repair job carried out. If this is the case, your roof cost will be relatively low compared to a new roof cost.

There are other roofs to consider too, which includes the roof of your garage or even your shed. These will need to be repaired or even replaced, depending on if any damage that has occurred. The cost of a new roof replacement for smaller outbuildings is relatively small compared to a roof on your actual home.

You may expect to pay around £1,000 for an entire roof replacement for garages with flat roofs. This cost is for a felt roof, whereas a shed roof wouldn’t cost as much – this is because it’s a lot smaller in size. It will cost between £300 to £600.

Price-changing factors may include the type of felt they use (there is a variety of felts that you can fix to your shed) labour costs, and the size of your shed roof.

Roof replacement costs for a house roof are a lot more, as you can imagine, and many people prefer to repair the roof instead to keep costs low. If you need to replace your roof entirely, then the price of a new roof cost will be between £4,500 and up to £6,000. It sometimes even exceeds this.

The cost of roofing repair work will depend on what needs to be replaced, but it will be much cheaper. If you need around 1 or 2 roof tiles replaced with new tiles, then the cost will vary depending on various factors. But expect to pay around £100 to £250.

What Are the Factors That Will Increase or Decrease the Overall Costs When Replacing A Roof

As mentioned before, a typical question when thinking about a roof replacement is how much does a new complete roof cost. The overall tiled roof costs will be different for many properties around the country, as many contributing factors will make a difference in the total price.

Here are some of the factors that will impact the cost of a new roof replacement.

1. The Size of the Roof That Requires Replacement

Roof sizes vary and, depending on what type of property you own, the costs will change. A new roof cost for a terraced house will be among the lowest priced, with a semi-detached house being slightly more. A detached house will be more expensive than both when it comes to fitting a new roof.

This is because, generally, a detached house will be larger than the other two property types. It will contain more roof square footage than the others. The cost will increase, as many roofing contractors will use measurements per square foot to help them work out the prices of roof tiles.

If you’re having a new flat roof, for example, on your garage or porch, the costs will be lower. A roofing contractor will work in the same way as for a house roof and use the per square foot measure to help decide on the number of materials that will be used for the roof replacement.

With the popularity of modern and contemporary new-builds or uniquely designed abodes, many of these include a flat roof in their design. These flat roofs will also need to be maintained over the years to ensure they are protecting the property. At some point, you will need a complete flat roof replacement. The total cost of a new roof will vary depending on the size also, and the property may feature several separate roofs. This will increase the cost to replace them all.

2. The Type of Roof Style That You Have

Just like the size of your roof, this is another factor used to work out the overall cost of your roofing work. Unfortunately, these factors can’t be altered to keep costs down as the size and style of your roof is non-changeable.

If a gable roof style has been used to create your roof, then the good news is this will carry the lowest cost. This is because of the way it’s designed. There’s a central point, and the roof slopes down on either side to cover the house. An average cost for a roof of this style is around £5,000, although it can be lower or higher, depending on your postcode and the roofing contractor.

Another popular roof style is the hip roof. This cost slightly more, at around £1,000 more than a gable roof, for an average semi-detached house.

If each of these roof types also includes valleys – there can be more than one – then this will increase the overall roofing costs. The cost can quickly increase by around £1,600 for a home that has two valleys built into the roof style.

Flat roofs will reduce costs slightly due to these being lower in per square foot measurements. However, that is dependant on other aspects, too.

3. The Condition of the Existing Roof Structure

You may not have considered this factor previously, but it’s also essential. There’s no point in replacing a roof if the structure is damaged in any way, as it may affect the new tiles that will be laid.

The condition of the roof beams will need to be assessed to ensure they are in good condition and not suffering from any damp or other issues. You’ll want your beams to be as strong as they can be to support the tiles on your roof, especially if you’re using slate tiles. These are heavier than a lot of the other tiles used in roofing.

Another main feature that should be checked or replaced is the underlay that goes beneath the tiles. This prevents water from entering the roof. If any tears or holes are found, it’s a good idea to replace those areas. Or if it’s been many years since it was replaced last, it may be worthwhile having a new underlay or damp protection layer installed to cover the entire roof.

4. The Type of Tiles that will be Used for the Replacement

This will have a significant impact on the overall cost to replace your roof. The size and roof style will be a deciding factor of how many tiles will be required for the new roof replacement. The number of tiles required for each square foot will be used when roofing contractors price up the job.

There are a few choices of tiles that you can select from. You may choose to have the same type of tiles that you used before. Or, as long as the roof structure is accommodating, you could use different tiles to change the look of your new roof.

The most common types of roofing tiles that are used are cement, clay, and slate. The cheapest tiles to select are cement tiles, but as you can guess, they have the shortest lifespan when it comes to weathering. However, they will last under 50 years.

Clay tiles are mid-range tiles and will increase costs slightly but may give a longer lifespan than 50 years.

The most expensive is slate tiles. These are very hard-wearing and will withstand the weather elements over 100 years. The slate tiles are also very heavy in weight compared to the other tiles, although cement tiles can be heavy too.

You will need to ensure your ridge tiles are made from the same material as your roof tiles. This will make sure you have a good finish, and the tiles are of the same specifications. If you have a gable roof, the number of new ridge tiles you need to be used will be less than a hip roof. A new flat roof won’t require any ridge tiles.

A slate tiles roof price is also more expensive. This is due to it taking more time to fit this type of tile. A slate roof needs to be carefully laid, so ensure your roofing contractor is skilled in this area. A slate roof replacement cost can easily be more than £10,000 or under, depending on the size of the new roof. These roof tiles are premium rate.

If you have a flat roof, you can have roof tiles laid. This type of roof will need tiles made from either wood, slate, or stone to create a practical and durable roof. If the slate is used, this will also carry a high price tag but will have a nice appearance.

This is the same as with a sloping roof style. However, the flat roof may not be visible; it may be worth just using felt for this roof type instead to reduce costs. But it’s entirely up to you and your budget.

Is A Roofing Repair A Better Option?

As you can see from the above information, replacing a roof can be very expensive. This is why many people opt for a roof repair, as opposed to an entirely new roof.

We can define a roof repair as only needing one or two roof tiles replacing. Or maybe one roof ridge tile needs to be changed. These types of roofing replacements won’t carry extremely high costs but expect an average cost of £100 to £200 to repair a few broken tiles.

There are other costs to consider when thinking about roof repairs, such as the flashing. This is an important feature that prevents water from seeping into your property.

It creates a water-tight bond around areas like the chimney or windows (such as those found in a loft conversion). The flashing will make sure water cannot get through the joins from tile to the window frame.

The flashing repair cost is based on how much is required and how long it takes your roofing contractor to complete. Labour costs will probably out weight the cost of the raw flashing materiel. You should expect to pay between £80 to £250 for this type of roof repair.

You can do various roof repairs on a flat roof. These repairs include removing blisters that have appeared over time and quick patch-up repairs, where the roof material may have worn slightly or received a small tear. These costs will sometimes be cheaper than tiled roof repair costs, but you may require more repairs to be carried out.

One of the downsides to having a flat roof is that water can build up on the roof. This will damage the roof material if a large amount of rain has fallen and is trapped on the top – it can be too heavy for the roof to handle. So beware you may need to replace this more often.

Full Roof Replacement vs. Roof Repairs

It depends on how bad the damage is and when you last replaced your roof.

If you can go for a repair, as opposed to a full replacement, it will cost less. But if the roof has begun to weather and damage in various areas, then it may be worth paying out for a full roof replacement.

The main reason to ensure your roof is free from damage is to prevent water damage to your home. This, in turn, will lead to damage inside the house.

One type of damage is mould build-up – you will notice damp patches too. If the damage is extreme, it could include issues such as woodwork damage and a more costly bill.

To decide on the best option for your home, you will need to think about the full replacement costs. If the damage is quite bad, or if the roof isn’t that old, a repair roofing fix might be best to save on the money front.

You May Encounter Additional Costs To Fix Other Features

Unfortunately, like many replacement jobs around the home, the roof repair or replacement may uncover faults with other features that keep the roof from operating at optimum working order. They may need to be replaced or fixed, and this will involve further costs.

The guttering surrounding the roof may be old and obsolete. If you have old guttering, you may want to consider having this replaced when the roof repair or replacement is taking place. Plastic guttering is a popular choice and material-wise, it isn’t too costly.

The guttering is vital as it allows water to drain away quickly without it going against your external walls. Guttering prevents damp getting inside your home, as well as damage to the brickwork and rendering.

If you don’t need to replace your guttering, you may need a gutter clean instead. Sometimes, a build-up of leaves or sludge can form inside the curved gutter. It’s a good idea to have the gutter cleaned to remove these issues.

A blocked gutter won’t work well, and the rainwater may spill over the top, depending on how bad the blockage is. This will cause damage to your home or create a waterfall effect every time it rains – and you don’t want that!

The roof fascias and soffits may need to be replaced or repaired. The cost of a new fascia and soffit board will typically be quoted separately from the overall cost of the roof repair or replacement. This is the same for the guttering work, too.

Other Additional Costs To Be Aware Of

There are a few other cost-increasing factors to be aware of when having your roof repaired or replaced. As a roof isn’t commonly replaced or repaired that often, you won’t be used to thinking about the other costs.

To fix your roof and be able to work safely on it, your contractor will need scaffolding to be placed around your home. Scaffolding is an essential safety measure, so there isn’t any way to get around this cost. It allows the roofer to get onto the roof quickly. The scaffolding will generally consist of a few levels.

It will need to be in place before the roofing contractor can start, so ensure these are booked well in advance. Your roofing contractor will possibly use their own trusted scaffolding company or will suggest a reputable one. The cost will be included in your overall price, or you might need to pay separately. Discuss this with your contractor.

The removal of the old roof tiles may not be included in the overall roof work. You will need to check with your roofing contractor to find out if you need to facilitate a way to dispose of them yourself. If this is the case, your best option is to hire a skip, as it will have enough capacity to fit in all the old used items.

The price of skips will vary, so to keep costs down, ensure you hire an adequate one. Make sure it’s not too big unless you have other household items to get rid of. Its a great way of cost-saving in the long run.

Labour costs will be included in your roof quote. Although, as with any home improvement, unforeseen issues can arise and additional days of work may be needed to complete the roof work. If this is the case, and depending on the contributing factors, you may need to pay more money per day for additional work to be carried out.

The additional cost of this shouldn’t affect every roofing job, but just bear in mind it’s a possibility. Depending on where you live and the fees that your roofing contractors charge, you could be looking at around £200 to £250 per day for additional labour costs.

What is the Best Way to Minimise Costs?

Minimising costs as much as possible is on everyone’s mind. This is whether you’re thinking about roof repairs or roof replacements. Just like many big structural features of your home, the roof is a costly feature to have fixed.

But, the roof is essential to prevent other damages occurring within the rest of your home. Water damage is one of the top issues if your roof is not in good shape.

You should use a roofing contractor who is reliable and trustworthy to keep costs as low as possible. It may sound strange to say that, but some people think to save costs they should hire a person who might initially seem cheaper than an established contractor.

The benefits of using a roofing contractor that has good reviews and is trusted are that they are experts in their field. They will charge a reasonable rate and carry out the work to a high specification as they want to continue to receive work and have a good reputation.

They will also know how much the job is likely to cost and the amount of time it will take them to finish. Whereas with an extremely cheap roofer, you can’t guarantee the work is going to be executed to a high standard. They also might add additional days for the completion of the work, which will increase the cost in the long run.

Another way to reduce the overall cost of your roof repair or replacement is to use second-hand tiles instead. A roof made with these can still be of a high standard but might not last as long. You can even use the ones from your roof if they are in good condition. This will reduce the price.

What Are the Indicators That Highlight An Issue With Your Roof?

Sometimes, roof damage can go unseen for a while. It’s not every day you look up at your roof as you leave and come home. Also, as it’s not very accessible even if you were to look at the roof from the ground level, you might not visibly be able to see any issues.

A roof issue is usually highlighted when it’s caused a bit of damage inside your home – or it could just be the age of it.

Age is a factor you should consider. Over time, your roof will weather slightly, and depending on the material used to create your roof, it might suffer from damage.

If it’s been a long time since any repair work has been carried out on your roof – say around 20 or 25 years or less – the best thing to do is get a roofing contractor to conduct an inspection. This will give you peace of mind. If any issues are uncovered, the good news is you can deal with them and ensure your roof is watertight.

Water damage inside your house is an indicator that something isn’t right. The water damage could be on the ceiling or walls. If you notice this, get someone in as soon as you can.

Leaks around the chimney will cause issues. If the flashing isn’t adequate, rainwater will easily seep in. Older chimneys can sometimes have flashing that has been weathered. If that’s the case, you should get this updated to ensure a tight seal.

If you have a loft conversion that includes any roof windows, make sure the flashing around the windows is in good working order. You don’t want water falling through here either.

Another sign to look for is if you see any daylight coming into the loft conversion. This will also mean there’s a roofing repair needed. If you don’t have a loft conversion, then you would need to check your loft for signs.

From the ground, you can walk around your property and have a look if any tile seems out of place. If you have seen one fall to the ground, this will need to be looked at straight away.

If you notice that, during heavy rainfall, your gutter doesn’t drain away water efficiently, this should be looked at. It’s an important feature that helps your roof system work.

How Long Should I Expect My Roof Work To Take?

This will depend on whether it’s a repair or a replacement.

If you’re having a repair job carried out, and it only requires a small amount of work (such as a few tile replacements), this will probably be completed in 1 day. However, this will depend.

A repair job that requires a few patch areas to be fixed might take a day or two for completion.

The longest work duration will be for a full roof replacement. This will require scaffolding to be installed at least the day beforehand. Then the removal of the old roof, any repairs or replacements to beams or felts, and then for the new roof to be laid.

The scaffolding will then need to be removed. An external contractor might recommend it stay in place for a while after the work is completed. This depends on how the schedules meet.

The size of the roof and the style will have an impact on the duration of the work, but for a gable roof, it will take around three or four days to complete, whereas a gable roof with two valleys could take up to five days.

For a regular semi-detached property, expect at least one week for the work to be completed – and possibly a few extra days. This time will also increase if there are valleys on the roof.

Unexpected issues can always arise, so sometimes, the work will take longer. But as long as you have a quality contractor, the work should stay on schedule most of the time.
