Lots of commercial buildings have flat roofs, which are often made from felt, asphalt, EDPM rubber or fibreglass, while others are pitched roofs that might be made from tiles, shingle or metal. It’s likely that your commercial roof will need replacing if it’s more than 25 years old. A roofer can carry out an inspection to determine what, if any, work is needed, but there’s a high chance that you’ll need a roof replacement if it’s that old. If your flashing is looking worse for wear or you’re missing a number of tiles or shingles, it might be time to replace your commercial roof. So how much does it cost to replace a commercial roof?

With that type of events, you’d expect to find some chimney pots on the floor or roof tiles to go missing every once in a while. When these minor roof issues occur, a professional roofer is always in hand to easily resolve these problems. However, there are times in which the roof will be in a terrible condition with persistent leaks which is beyond the capacity of a roofer to resolve. In such cases, you may have to consider having the roof replaced as the best choice.

In the UK, a roof repair cost can be within the range of £100 to £12,000 based on a number of influencing factors such as where the property is located as well as the size of the property. For instance, if you happen to stay in London where the demand is higher and there’s also the high cost of living, roof repair costs tend to be a bit more costly.

Let’s look at a simple breakdown of some roof repair jobs. These includes the following:

✓ Cost of renovating the roof on a detached four bedroom house using slate ( two story house) will range between £6300 to £12000.

✓ Cost of renovating full roof on a two bedroom bungalow using slate will range between £4000 to £5900.

What is a pitched roof?

A pitched roof is a type of roof that is defined to have a sloping surface that has an angle that is greater than 20 degrees. Pitched roofs offer a more classical appearance. They remain the most communal and effective answer in wet and cold weathers to guarantee all-out protection.

Eaves

In the roof, the lower part of the inclined roof which is prominent outside the external face of the wall. The chief purpose of eaves is to pour the rainwater from the roof straight on the exterior wall. It also provides protection from sunlight. Eaves are sometimes decorated to an architectural beauty.

Gable

The Three-sided higher part of the wall at the end of a ridge roof.

Flashing

A band of impermeable material, typically metal, used to eliminate water from the intersection between a roof covering and another part of the structure. Flashings are provided to stop moisture from inflowing the wall and roof through joints in copings, parapet wall, and other infiltrations through the roof plane.

Hip

The Hip is defined as the exterior angle, which is generally greater than 180 degrees, which is formed at the inclined ridge of the roof slopes.

Ridge

The ridge is defined as the horizontal intersection made by the rising roof surfaces that are inclined in opposite directions.

Purlins

Purlins are the horizontal members which are laid on the principal rafters which help to support the common rafter of a roof. This is usually done when the span is large. Purlins are made from wood or steel. The top surfaces of the purlins intend to be unvarying and plane.

Fascia

This is the wooden board that is fixed to the feet of the common rafter at eaves. The Fascia helps the lowest ends of the roof covering material to rest on it.

Rafter

One of the major structural components of a pitched roof is a rafter. The rafter generally begins for the support of the roof to the ridge or hip. The purlin is supported by equally spaced rafters used side by side.

If your commercial flat roof needs replacing, how much it costs will depend on how big the roof is and what you want it to be made from. Lots of commercial flat roofs are made from felt or asphalt, but people are also beginning to turn to materials like EDPM rubber and fibreglass. Flat roofs can last a long time, but if it’s been 20 years or more since you had it replaced or inspected, it might be time for a new one. If a roofer inspects it and finds lifting, flashing problems, sagging or lots of blisters, it’s probably time to replace your flat commercial roof.

It depends on how big your roof is and what material you choose. Felt is the cheapest material you can use for your commercial flat roof, at around £40-70 per metre squared, while a lead bay roof will cost the most at £90-110 per square metre. EDPM rubber and fibreglass roofs are being used more and more because they’re so durable, and they will cost between £80 and £110 per square metre. It might be worth spending a little more upfront to get a stronger and longer-lasting commercial flat roof.

How to plasterboard around a Velux window?

While it sounds like it could be difficult to plasterboard around a Velux window, it needn’t be. As long as you have the right tools and materials, you should be able to plasterboard around your roof window easily and make good ready to be skimmed. When you or a tradesperson has fitted your Velux window into your roof, you’ll probably need to plasterboard over it to create a good ceiling. To do this, you’ll need:

  • Plasterboard sheets – make sure you measure your room so you know how much you’ll need
  • Screws to secure the board in place
  • Drill
  • Hammer
  • Straight edge and pen knife to score the board before trimming
  • Fine toothed saw the cut the plasterboard

When you’re ready to plasterboard around your roof window, make sure you’ve cleared enough space to work in. Then you can begin by cutting your plasterboard to size using your straight edge and pen knife to score, then your saw to get a clean cut. A common way of plasterboarding around your Velux window is to use the groove on the window frame to hold one edge of the board, then screw the other edge to the battens on the ceiling. People often use drywall screws these days as they have a better grip of the plasterboard as they drive through. You’ll need to use a drill to screw these in. However, you could use plasterboard nails, which are galvanised to stop rusting. When you’ve done this, you can then skim the walls or ask a plasterer to do it for you. Plastering, while it looks easy, is a tricky skill so it’s always best to ask a professional to do it.

Can you repair a flat roof in the winter?

Yes – you can repair a flat roof in the winter. Contractors will still be able to help you repair leaks, and it’s a myth that they will charge more. Most won’t have any additional costs just for coming out in the winter.

You'll have to wait for any snow and ice to melt before you can repair your flat roof. Depending on what type of flat roof you have, some repairs might have to wait until temperatures reach a certain level above freezing – some coating products won’t adhere (stick) in low temperatures, but a roofing professional will be able to advise you on what is best to use in the winter. If you have an EDPM rubber roof, most of the adhesives won’t mix in cold weather, so you might have to wait until temperatures rise to get a proper repair to your flat roof.

The best way to avoid needing to repair your flat roof in the winter is to inspect it at regular intervals. During the summer, even in the UK’s mild weather, the sun’s UV rays can damage and weaken flat roof surfaces, potentially causing cracks and holes. As autumn approaches, take a look at your flat roof and see if you notice anything untoward. If you do, speak to a reputable roofer who can repair your flat roof for you before winter arrives.

how to identify asbestos roof tiles?

How To Identify Asbestos Roof Tiles

Found in some particular rocks, asbestos is a naturally occurring mineral that’s commonly used before the 1990’s as a building material specifically for roofing. This material was banned in the UK as it was discovered to possess harmful fibres which is potentially dangerous to human’s respiratory health when disturbed and inhaled. According to several reports this health conditions include non cancerous lung disease, mesothelioma and asbestosis, which are all untreatable. Therefore, be it in a domestic or industrial setting, there’s the need to know how to identify asbestos and if found, start the removal process as quickly as possible.

While the three types of asbestos used in roof tiles can be quite easy to identify by themselves, a total reverse is the case, when mixed into a tile. Generally roofing tiles that includes asbestos will mostly have colours such as grey, white or blue-white colour, but so does several other roof tiles made from other materials that are totally safe. As a result, the only way in which you can identify if a tile contains asbestos is by looking for an identification mark. These marks are mostly inscribed onto about one in twenty tiles, therefore if you have a strong feeling that your roof tiles contains asbestos, you may have to remove several tiles before you can identify the marked one. Otherwise, the only way you can confirm is by sending a sample to a certified asbestos testing lab. These labs are knowledgeable and possess the right equipment, tools as well as testing kits to determine the levels of asbestos in your premises. With this, you have a better chance of getting quality results than any other means. What’s more? They’ll also recommend expert asbestos removal services if the harmful material is found to be present in your house.
