Blogs and Advice
What are the benefits of flat roofing in Northwich?
Cost: Constructing a flat roof usually takes less time and uses fewer materials than a traditional roof, which means it costs less to install.
Warmth: Flat roofing in Northwich can keep your home considerably warmer than their competitors, especially during the cold winter months. This is because the flat surface area attracts sunshine which then penetrates into the home below.
Versatility: Versatile internal and external space. It can be used as a patio, garden, outdoor swimming pool or just a communal outside area.
Accessibility: Flat roofing in Northwich is more accessible, making it easier for new installations and repairs.
What are the disadvantages of a flat roof?
Draining: The biggest disadvantage of installing a flat roof in Northwich is the danger of water and other debris gatherings, which gradually can make the roofing material to break down or to crack.
Maintenance: This is a very important factor when considering whether to install a flat roof in Northwich, as they require a lot of it.
Lifespan: The average lifespan of a flat roof in Northwich is 20 years, and that’s only if it is properly maintained.
Materials: There is a lack of roofing materials available to use and the vast of majority of flat roofs use rubber, EPDM, TPO, or bitumen, which are relatively cheap and easy to install but have a short lifespan of 10 -15 years.
Styling: This is another limitation mostly because of the lack of materials. However, rubber singles can now be used in conjunction with rolled up roofing and several other materials such as polycarbonate roofing and PVC roofing, that can improve the styling of the roof at a higher cost.
What types of flat roofs are there?
Any material used to construct a flat roof in Northwich must be watertight because even though flat roofs are built on a slight incline, they are still very susceptible to leaks. That said, there are five main types of flat roof: roll asphalt, single-ply, multiple-ply, modified ply, modified bitumen and flat-seamed metal.
- Roll asphalt flat roof
Roll asphalt is made up of layers of asphalt-coated fibreglass, tar, felt and water-resistant materials, all of which are kept in place with nails or asphalt cement. The top layer is covered with gravel, which protects the roof from ultraviolet rays. This type of flat roof has been used for over 100 years and is generally the cheapest; however, it doesn’t usually last much longer than 10 years.
- Single-ply flat roof
Single-ply flat roofs in Northwich are made from one layer of materials that are a bit like rubber. These materials cost less but are studier and more energy efficient then roll asphalt roofs. Usually, single-ply roofs are made from EPDM, uPVC, ethylene and TPO. These are all mould resistant and low maintenance. Single-ply roofs usually last for up to 12 years.
- Multi-ply flat roof
This type of flat roof is made up of lots of layers of fibreglass, which is packed between layers of asphalt. The big benefit of multi-ply flat roofs is that they are reinforced, so they last longer and are less likely to get damaged. They can last as long as 30 years.
- Modified Bitumen flat roof
Some multi-ply flat roofs use a modified bitumen membrane, which is made from a mixture of polymers and asphalt which makes it flexible and water resistant. The top layer is covered with gravel. These types of flat roofs could last up to 20 years.
- Flat-seamed metal flat roof
This is the most expensive type of flat roof, largely because it is made of metal such as copper and stainless steel. Metal flat roofs usually last between 20 and 50 years.
How much does a flat roof cost?
The price of flat roof replacement in the Northwich depends on factors like:
Flat roof specifications: Each job is different and presents different difficulties.
How accessible is the roof: The height of the roof and whether scaffolding is required or not.

The size of the project: For small projects, the cost is usually higher per square meter, due to time-saving and manpower considerations.

Flat roof repairs & maintenance
If your flat roof is in need of repair, you will first need to locate the problem. Usually, the first signs of a problem in a flat roof can be found in the room directly below; either damp patches or water dripping from the ceiling will be visible. Before climbing up to have a look though, think about the strength of your flat roof; it is old and has been damp for a while it could be rotten in areas and very dangerous. You should always hire a professional roofer to inspect and repair your flat roof safely.
A roofer will inspect the condition of the surface of your flat roof, looking for tears, puddles of water (referred to as ponding), holes or bare patches. The leak could also be coming from blocked drainage around the edges of the roof. If your flat roof is in a very poor state, your roofer may recommend replacing the roof entirely.
Hire a professional to repair your flat roof, which can be dangerous and cause structural problems if not carried out correctly. Before any repairs are carried out, a professional roofer will make sure the area is clean, removing any chippings and using a fungicide to get rid of any mould growth. It’s best to carry out repairs after a long dry spell of weather, meaning there is less moisture in the roof. Below is a guide to how a professional will repair a few basics in your flat roof:
Blisters in the felt
A roofer will clean the surface over and around the blister, making sure there are no chippings there and ensuring all mould and dirt is removed. They will use a knife in order to make a cross cut through the top layer, being sure not to press down too hard. Peeling back the segments created will allow the roofer to dry the area inside, perhaps using a heat gun. Once that is down, they will apply some bitumen adhesive to the surface and then put the segments back and press down to ensure it stays. The roofer is then ready to apply new pieces of felt, making sure there’s sufficient overlap to cover the repaired blister.
Splits and tears
If the roofer can lift the split or tear without damaging the felt, then they might do that, cleaning the space underneath it. They will then fill the space under the lifted split or tear with adhesive and press it down. Any larger spaces can be filled with bitumen compound.
You will find the sealing flashing (usually a zinc or substitute strip) where the flat roof touches the wall. The best way to repair this is to use one of the self-adhesive repair tapes. A roofer can do this by first of all cleaning the surface, cutting the tape to length and then applying it to the area, making sure that the overlaps are well sealed at either end.
Flat roof inspection advice
A flat roof needs regular inspection. Good water-flow when it rains means that your roof is still most likely in top condition. The usual signs that a roof that needs repairing are cracks on the surface and edges. You’ll often be able to tell if your roof needs a total replacement if you’re experiencing any leakage. If you notice this, get help from an experienced roofing company.
Roofing experts can visit your home and help assess the damage to help find the best solution for your home. Another tip for your roof is to always get rid of leaves and random items from piling up at the gutters to avoid uneven weight as this can distort your roof and lead to unnecessary damage. It’s also a good way to get rid of mosquitoes from setting up an environment there.
