Roof Replacement Cost

Roof replacement costs are usually determined by the roof’s size and the type of roofing material used. On average though, the cost of a new roof in the UK hovers between ₤2000 to ₤10.000. Prices are also affected by the building’s location, its accessibility, and roofing damage. These prices only include the services of labour and the purchasing of the roofing materials only for a roof replacement and not alterations of the building structure or design.

What Are The Signs That Your Roof Should Be Replaced?

Sometimes a roof does not need any major signs of wear and tear to need replacing. One might feel compelled to get a new look or just a simple replacement as a preventive measure of future roof damage. The older the roof gets, the more a need might arise to have a roof replacement. The following are some signs that tell you your roof needs to be replaced.

The common signs to look out for

  1. Water damage

Water damage is one of the easiest signs that tell you your roof needs to be replaced. If you notice a spot or a few spots that drip water from the ceiling, especially when it rains, then you know your roof is probably leaking. Sometimes, there might be no drip, but a noticeable dark streak along a part of the ceiling or running down the side of your building will tell you that you have got some water damage to your roof. Other times a slight bulge or saggy part of your roof are prominent signs of water damage.

Roof replacement costs for water damage can range between £500-£900 for simple repairs. This will involve waterproofing and repairs to leaking pipes and damaged shingles. A full replacement will set you back some £1,200 for installing new shingles, replacing and resealing the flashing. Keep in mind that the roof’s size will be taken into account for the full roof replacement costs.

  1. Mould

The build-up of mould, moss, and algae are not always sure signs of roof damage. What compels you to replace your roof, in this case, is the unhealthy look of it. It is unattractive and a bothersome eyesore that will eventually get worse with time. Roof damage due to mold does sometimes occur as the mould traps moisture, causing water damage to the roof. To keep safe, whether the mould is an eyesore to you or not, be sure to get your roof replaced just in case the unattractiveness of the roof is not the only damaging aspect.

Roof replacement costs here will depend on the amount of damage the growth of the mould has caused and how much it has spread across the roof. The average cost of mould repair will get you spending between £1,500 -£3000. A small repair or removal ranges between £500-£1,500, while a larger area will cost around £3000.

  1. Cracks

Cracks can tell a lot about the type of damage that is happening to your building. Some cracks are simply what the industry calls ‘cosmetic’ cracks. These ‘cosmetic’ cracks are signs of an aging house and one that really doesn’t call for much concern. You need to be cautious about the other cracks that tell you of structural failure and roof damage. Since a crack in the ceiling is sometimes difficult to tell which kind of crack it is, whether a ‘cosmetic’ one or a roof damage warning, it is best to treat all cracks with urgency as some cracks are caused by water damage, structural issues and temperature fluctuations that expand and contract the roof.

Repairing a small crack in the ceiling has an average cost of £150. This involves sealing simple leaks and replacing affected shingles. High-end roof replacement costs are for massive overhauls when cracks in your roof spell trouble of structural issues. This can involve removing and installing all shingles on the roof and repairs of the materials under the roofing layer and can cost around £3000. 

  1. Missing tiles

Missing tiles can cause more damage than you might think. Roof tiles are built to withstand the natural elements, but they cannot withstand them forever. When you have a missing roof tile, it is one of the first signs to notify you of roof damage. With roofing tiles missing, certain parts such as insulation are exposed to outside forces like the sun, wind, and rain. Not fixing the problem quickly can lead to more extensive damage and higher roof replacement costs.

You can spend as little as £150 to replace missing roof tiles when it is in the early stages. High roof replacement costs will get you spending upwards of £1000 for major damages. In this case, it is best to replace those missing tiles as early as possible.

  1. Damaged flashgun

The seams and edges of a roof are some of the most vulnerable parts of the roof. Flashing is done to protect these areas. One common type of roof leak is caused by faulty flashing. As some of the most vulnerable parts of the roof are protected by roof flashing, any kind of damage to the flashing raises some unnerving concerns. Cracking in the flashing of the roof or bending and contorting due to temperature fluctuations gives space that allows moisture to seep in and eat away at the exposed seams. At times the seeping moisture can run along with the entire flashing and cause damage far away from its origin point. This is particularly annoying as locating the exact source of the seeping moisture becomes cumbersome.

The average cost of a flash repair ranges between £15 to £25 per linear foot. Badly corroded flashing will need to be replaced, though, and that will increase your roof replacement cost to around £600-£1,500 as you will need to remove rows of shingles and the old flashing before the installation of the new one as well as resealing after chipping the old mortar of the previous seal.

  1. Overflowing gutters

A roof gutter aims to direct the flow of water off the roof to prevent the roof from flooding. When the gutter gets choked during heavy rains, the water from the roof gets blocked from leaving. As the water begins to flow back onto the roof, damage can occur when the water pools up on the roof. Roof cracks, roof leaks and roof sagging can result due to the excess water on the roof. An overflowing gutter is a major sign that warns you of your roof needing a roof replacement. There are lots of variables used by contractors to determine the fee involved in a gutter repair or replacement. Variables such as the type of gutter and material, type of repair needed, gutter length and house height all factor into the roof replacement costs when solving a gutter problem.

The average costs to repair a gutter can be £75-£150 for materials alone with labour coming up to about £100-£150.

Noticing these common signs quickly can help a lot in deciding how high or low in roof replacement costs you will dish out. You may think that it is not often the case that a tiny crack or leak may warrant a call or an email to a professional to check it out for repairs or removal but solving problems early on can help save a lot of money.

The workmanship that goes into our roofing Processes

Replacing Rafters: Rafters act as the foundational element of a roof. They are structural beams usually made of wood that are designed to give support to the roof deck and all its accompanying load. One common damage that occurs with rafters is rotting. This happens when the roof leaks and moisture seeps into the rafters, causing rot and weakening the structure. The roofing support structure slowly deteriorates. It is critical to have a roof replacement as soon as possible before the roof comes crashing down.

roofing repointing

Repointing Repointing refers to the roofing process of resealing the ridge capping mortar of the roof. When the mortar is old and cracked, it allows water to penetrate through and cause some roof damage. To prevent this, repointing is done to replace the seal.

Waste disposal: It is not often that people think of roof waste but knowing how to dispose of such waste properly is vital for the environment. Consider including roof waste disposal in your roofing replacement cost. Some roof waste can be recycled, while others can be reused. Recycling and reusing parts is beneficial to the environment, which needs as much saving as possible.

Rainwater gutters: Rainwater gutters are used to redirect excess rainwater from an area of high concentration to an area away from wall exteriors and foundations. Roof rain gutters are important as they remove water away from the roof that can damage the roof if not taken care of.


Fascia and soffitsThe long straight board that runs along the lower edge of a roof is referred to as the fascia board. The fascia supports the lower edge of the row of tiles at the bottom. The fascia also supports the roof rain gutter. The soffit board, on the other hand, is tucked under the fascia board. The soffit board allows for ventilation to the roof area and prevents condensation, which reduces the risk of decay.

Loft insulation: The barrier of material within your roof space is referred to as loft insulation. Its purpose is to slow down the transfer of heat between the inside of the home and the outside. Loft insulation can help reduce energy bills from heaters and improve the overall energy efficiency of the home.
