When it comes to having a new roof for an extension or garage you may be torn between having a flat roof or having a pitched roof. Both have their advantages and disadvantages and you need to do your research before you commit.
Flat roofs often cost a fair amount less than a pitched roof, for a number of reasons. The materials that are used for a flat roof cost less and it is not so labour intensive to build so the labour costs are also less. They often are cheaper to repair as well so if you do need work doing in the future you may find that it is more straightforward and cheaper than repairs to a pitched roof.
If built correctly and with the correct planning you can even se your flat roof as an extension to your garden. You may be able to create access to it from a bedroom and build a balcony to allow you somewhere nice to sit out in the summer evenings.
With flat roofs easier to walk on, it makes maintenance a doddle. Cleaning out guttering, removing moss off the roof and even having access to clean windows is all easier with a flat roof.
