Styles of flat roofs
Contrary to popular opinion there are many styles of flat roof. Be sure to check which one is the best for your home or business:
- Modern traditional cold felt flat roof - insulation is placed between the roof joists to offer energy saving and thermal efficiency, helping you save on your energy bills as well
- Mono-ply system - a single sheet of material (for example, rubber) that seals the roof and makes it watertight
- Fibreglass roofs – strong, durable materials
- Green/living roofs - designed to have a grass like flora growing from the roof
Keeping your flat roof in good shape
Modern flat roofs offer a great deal of longevity and affordability. But to be sure your roof stays in peak condition there are a number of things you should be aware of…
- Make sure the fortifications are strong enough to withstand maximum pressure
- Protect from the elements with correct drainage channels and gavel-guard guttering
- Waterproofing height must at least 150mm from the surface of the roof
- Cover flashing should be used to protect the upper edges of the waterproofing
- Always check insulation
- Ask about ventilation – good ventilation will stop any condensation building up
What kinds of materials are used?
As with any home improvement, different companies will offer different practices, materials and prices. Here is our guide to some terms to familiarise yourself with.
Three layer flat roofing – bituminous felt set in three layers – is a highly technical but effective procedure and one that Pro Dec Roofing specialises in.
Single rubber sheet roofing – custom-made sheeting which is laid on to the roof boarding and is supported by the roof beams. Insulating material is placed in the space between the two.
This is growing in popularity and can be cheaper than the three-layer felting option.
Signs there may be problems with your roof?
Should you spot any changes in your roof or its usefulness, the best thing to do is to get it checked out. Do not wait for the water to come pouring in. The sooner something is rectified, the better the chance of long-lasting success which will in turn save you money.
Here are some warning signs to watch out for:
- Missing tiles
- Puddles forming or blistering
- Cracked flashing
- Falling mortar
- Debris in the gutter
Finding the right company for you?
When it comes to choosing a contractor, there is more to think about than just a good price. Speak to a range of providers, that way you will get a feel for their work and become more familiar with the terminology.
Always check their health and safety protocol; read the recommendations on sites such as Checkatrade; ask about guarantees and insurance; make sure you have set a completion date before the work is started; and discuss when monies will be due. When and only when you are satisfied, instruct the company with the task.
