What is a flat roof?


A flat roof is a type of roof that has no slope. It can be made from many different materials, including asphalt shingles and metal roofs. Flat roofs are often used in commercial buildings because they provide protection against the elements while allowing for easy cleaning. They also allow more light to enter the building than other types of roofs do.

However, if your flat roof needs replacement or repair, you may want to consider using an alternative material instead.

Flat roofs are usually made from concrete, but they may also be constructed using other materials such as asphalt shingles, metal panels, wood shakes, slate tiles, etc.

Types of Flat Roofs

The most common types of flat roofs include:

Concrete Slabs

These are the cheapest option available to homeowners who want to install their own roof. They come in various sizes and thicknesses. Slab construction requires little maintenance because it does not require any sealing or painting. However, slab roofs do have some drawbacks including high installation costs, limited design options, and poor insulation properties.


Tile roofs offer many advantages over conventional roofing systems. For example, tile roofs last longer than traditional roofing products, making them more cost-effective when compared with new installations. In addition, tile roofs provide excellent thermal performance due to their low R value. This means that heat will easily pass through the roof without being trapped inside your home. Finally, tile roofs look great on homes and businesses alike.

Flat_roofing_Farnborough services

Single-ply roofing

A single-ply roof is made up of modified bitumen, gravel, or crushed asphalt that is layered for strength and stability. It provides excellent protection against water penetration but does not offer much resistance against strong winds. Single-ply roofing systems are usually installed directly onto existing structures such as buildings, sheds, and garages. These roofs are relatively easy to repair and maintain.

Modified Bitumen roofing

In the late 1960s, a variant of built-up roofing (BUR) was developed in Europe: Modified Bitumen. Polymers are used to modify asphalt bitumen, which is then reinforced with fibreglass and/or polyester. The different layers are assembled in a specific way to increase the effectiveness of the roof. Modified Bitumen offers a number of competitive advantages no other roofing system can match.
In case you are unsure which one of these flat roofing types is right for your property, our experienced roofers can help you choose the right material design that suits your needs. After you’ve decided on a design, we will construct a roof that is strong, water-tight, and beautiful.

GRP Fibreglass Roofing

Fibre glass roofing is an attractive alternative to traditional roofing products. GRP fibreglass are extremely durable and resistant to damage caused by wind and weather conditions.

EPDM Rubber Roofing

Rubber roofing is a type of waterproof membrane designed specifically for use over flat surfaces. EPDM rubber roofing is available in a variety of colours and designs. This flexible membrane is ideal for commercial applications where durability, flexibility, and ease of maintenance are required. It is also suitable for residential applications where its low price point makes it an affordable option.

Roof Coatings

Roof coatings are another popular choice for flat roofs. They come in many different styles, including colour options, textures, and patterns. Coating materials include elastomeric membranes, metal sheets, and self-adhesive tapes. Roof coatings provide additional benefits such as UV protection, increased insulation value, and improved fire safety.

Felt Roofing

Felt roofing is a very versatile roofing product. Roofing felt comes in various sizes, shapes, and colours. It is lightweight and highly resilient making felt roofs deal for homes and businesses alike.


The gutter is a channel designed to catch rainwater runoff from the roof. Guttering is an important part of any roof because it helps prevent water damage to the structure below. Our skilled roofers can help you with your gutters as well.


Leadwork is usually done to make your roof weatherproof. Our tradesmen are proficient in lead works as well.

Roof Tiling

Tiles are a very common roof covering option. They are highly versatile and can be laid in almost any pattern. They are also easily cleaned, making them a practical and economical choice for flat roofs. At Fortis Roofing, our roofers are proficient at tiling work such as tile repair, retiling and installing new tiles.

Roof Windows

Windows are an effective way to add light and ventilation to your home while providing protection against the elements. We have expert window installers who can fit windows into your existing roofline. In addition to this, they can also replace old windows with new ones. We work with only superior brands such as velux windows.

Flat Roof Installation
and Flat Roof Replacement

Flat_roofing_Farnborough installation

No one likes to think about their roof. But when a leak, storm, or other event occurs, it’s at the top of everyone’s mind. And it can be stressful and costly to fix this problem. Flat roofs deteriorate because of age or weather-related factors and leak, rot, and may collapse – they become a concern for your safety and the safety of anyone underneath.

At Fortis Roofing, we believe in customer satisfaction and the integrity of your home or business. That is why we always insist on using only the best materials to ensure that you are happy with our roofing work. 

Flat roof repairs or re-roofs are expensive and often require professional help. The problem is that most roofers aren’t great at how to install them correctly so homeowners end up having leaks that cost more money than it would take to fix them from the start. If you’re considering getting a new flat roof then you should look for a roofing company that has the expertise to do the job well.

Flat Roof Repair, Restoration,
and Maintenance in Farnborough

Roof Cracks

Flat Roofs do crack eventually because of many factors including weather. We fix all types of roof cracks. While we are at it, we also check on your fascias and soffits and ensure they are in top shape.

Leaks and Moisture Seeping

A flat roof can be vulnerable to leaking and moisture seeping in. To identify where the leak is coming from, you should hire an experienced roofing contractor. They will be able to assess the roof, locate the leak, and fix it.

Water Pooling

Water may pool on flat roofs due to certain areas becoming lower than the others. Pooling water on a flat roof is a problem that plagues all flat roofs. When standing water sits on a flat roof for an extended period of time, it can lead to water damage to the roof.

One way to prevent pooling on a flat roof is to install a drainage system. The drainage system should be installed on the outer edge of the roof and should be sloped. Any standing water that accumulates will drain away from the house.

Membrane Buckling

Buckling is the bending of a structural member under load. The phenomenon happens when the point at which the structure is being subjected to the load is in compression, and there is not enough resistance to prevent buckling, or there are not enough connections to keep it from buckling. This is because when a structure is under compression, it cannot withstand the force if it is not connected to anything else. We also do re-pointing of your roof if it’s necessary.

Damaged Flashing

The constant change in temperature may dislocate the flashing from the edges and corners. One of the most common causes of water entry is damaged flashing. Flashing is a metal or PVC material placed over the roof’s edge that seals the top of the wall from water.

Flashing can be installed in a variety of ways, but it typically is installed as part of the lower fascia and seals around the edge of the roof. If the flashing is not properly installed, or if there are cracks, breaks, or holes in flashing, water can enter your home.


Some flat roofs will develop what is known as alligatoring. This may be a patchy, scattered, or full-roof phenomenon. The most common symptom of alligatoring is the development of small and large cracks in the roof.
