When working with a roofing contractor in Florida you need to ensure that the building meets all codes. Doing so gives your roof a longer life, keeps all occupants safe and reduces the number of repairs you have to make on the roofing system.
There are several benefits of installing a flat roof on your house or commercial property, such as:. The materials and labor needed for a flat roof is much less than those of a sloped roof. For instance, TPO is mechanically attached or adhered to a roof surface. This method of applying a roofing system requires fewer materials and much less labor than trying to manually attach roofing material to a sloped roof, where it takes more effort to complete the job.
You spend less money without sacrificing quality of craftsmanship. Roofing contractors generally recommend that you stay off the roof. However, there may be times when getting on the roof is necessary. Some roofs have features such as balconies or other amenities that give you access to the roof. If so, accessing a flat roof is far easier than trying to scale a sloped roof.
Some communities in Florida impose height restrictions on new construction. A sloped roof may give you less livable or workable space if you have to adhere to the height restrictions. If you have a flat roof, you can add more livable space without exceeding the restrictions. For instance, in a commercial building, you may be able to add another floor if you choose a flat roof. If flat roofs are to work well, they have to have a slope, known as a fall, to shed rainwater.
The fall should never be less than and preferably about There are several methods of building in a fall:. How exactly a fall is built in largely depends on how the flat roof is built. There are three main choices:. Condensation risk analysis is habitually undertaken by designers to ensure that any potential dew point that might occur within the roof itself is eliminated.
Over the years many products have been used and none has emerged clearly as the best. In practice most people plump for the system their installer or designer likes the most. Generally speaking, the issues to watch are the cost and the guarantee offered. Applied hot in two or three layers, it remains potentially the cheapest covering but there are several different grades you can specify.
The best felt systems are now comparable with any of the alternatives but cost just as much. And the fact that it is applied hot makes it easier to form around penetrations and corners.
There are two basic types of MBS systems: 1 Torch-down systems and 2 self-adhering systems. Torch-down systems use a special combination of layers to torch-seal the bituminous product layers with the help of specially designed substrates. It works for all stand-alone roof situations where a torch-application is acceptable.
The GTA membrane is preferable to the self-adhering option in most cases. The SAS uses coated bitumen basemat to provide a waterproof seal on flat and low-sloping roofs. This product is ideal when a torch cannot be used. Looking for a contractor who can tackle the unique needs of a flat roof system? Long Roofing fits the bill.

A gutter is a long, open water collection pipe installed at the edge of the roof. Gutters are the most common type of drainage systems used throughout the world and can easily handle large amounts of rainwater.
Debris from rainwater can quickly get stuck in those gutters, which reduces their efficiency. Gutters also tend to crack and break, causing them to become completely ineffective.
Inner drains are used mostly in industrial and commercial buildings with large roofs. They collect water from holes in the roof and lead the water through a long chain of pipes built into the roof.
However, inner drains tend to be expensive to install because they are built into the roof during construction. Also, if some debris does get stuck in the pipes of inner drains, only a technician can unblock it. You also need to install enough internal drains if you want to drain out all the water from heavy rainfalls effectively. Scuppers are perhaps the most affordable yet effective draining methods of all.
A scupper is just an opening in the roof connected to a small metal pipe that allows rainwater to run through.
