Has to be built up to form a good surface and this takes time and materials
Weather and temperature dependable
Other options to consider
All three are based on the principles of GRP resins and glass fiber but they have been modified to be flexible.
If the GRP roof is laid correctly and to the correct depth they are good roofs however I only ever see well laid GRP roofs when Im down the coats these are normally laid by boat builders and are formed from may layers of GRP, forming a good strong shell.
If you have lots of money and want a really nice looking roof then GRP is the way to go.
It’s not often we get asked to look at a flat roof as large as this and unfortunately our free estimate wont cover the cost of surveying this roof and reporting back the findings.
This flat roof is a round 1500m2 and is covered with an old type flat roofing membrane with welded joints, this type of roof is still being fitted but we consider it to be one of the older generation flat roofing materials.
I’ve taken a walk around the inside of he building and seen where the water is penetrating, externally I have examined the roof and can see lots of design faults, I will be submitting a preliminary report suggesting that thermal imaging of the roof is undertaken to show where the insulation is saturated this will help identify the areas of the roof where the roof has taken on water, then we can scrutinise each joint and visually inspect the membrane for holes punchers or rips.
At this stage I think we will be cutting out all the wet insulation then repairing the roof using a liquid roofing systems such as GacoRoof.
The brick parapet wall is solid construction but the flat roof is built on timber and will settle over time, the asphalt will melt in the summer and go brittle in the winter, with the thermal movement the cracking occurs.
So after cleaning of the roof taped patches are applied to the cracks before the new roofing system is installed to the roof.
On this roof we are using the GacoRoof a silicon-based liquid roofing materials from the USA . GacoRoof is very flexible and can withstand the movement described above.
The other interesting factor to all of this is the color of the finished roofing materials GacoRoof has a white finish and reflects the sun’s heat stopping the old roof from melting
If the roof is covered with obstacles such as skylights, pipes, air conditioning units and so on then a liquid roofing system should be chosen.
I alway explain to my customers we don’t choose the flat roofing system for the roof the roof and your budget chooses the system.
The new Liquid roofing system we are using on this roof is ideal as an overlay system for old flat roofs, the advantages of the GacoRoof liquid flatroofing system is that its snow white when completed reflecting all the suns rays int he summer.
Recently we have been overlaying an old asphalt roof in Wembley with a new silicon-basedliquid roofing material called Gaco Roof. I took the opportunity and made a video, hopefully explaining how we can provide an estimate of the cost of a new flat roof over the phone, using information given by the customer.
The new roofing system, Gaco Roof, that we are using here is a new silicon-based liquid roofing system and is relatively new to the UK. GacoRoof is made in the USA and has had quite an eventful life over there; we have been using it now for the last 5 months and it’s
becoming one of our favourite liquid systems.
Liquid roofing systems all have their respective advantages and disadvantages. If you have been following my blog, you will know that over the years I have been trained to use several different liquid roofing membranes, and after extensive testing, if a system is found not to be that good, we will stop using it. Ive found in general it take around about a year to understand a new liquid roofing system you need to go thorough all 4 seasons before a complete understanding can be achieved.
