Is your roof emitting excess heat? Or is it consuming outrageous energy? Either way, it's a sign that your roof urgently needs insulation. However, it's advisable to insulate your roof during or immediately after installation. But if you've not done so, it's never too late to do it now.
Flat roofing insulation is a method applied by roofers to make your roof energy efficient and limit the degree of heat emitted by your roof.
There are two fundamental types of flat roofs, namely: warm flat roofing and cold flat roofing.
Warm Flat Roofing: This is a process whereby the insulation materials are above the roof.
Cold Flat Roofing: This is a process whereby the insulation is put in the middle of the joists under the roof surface above.
There are many materials you can use for a flat roof installation, but one of the most outstanding materials is the Polyiso.
Polyiso is excellent for both residential and commercial roofs. This insulation sheet has a thickness of about one to four inches. And it is regularly measured as four feet by four feet or four feet by eight feet.
Polyiso sheets can be either tightened or level. The tightened polyiso sheets are slanty: the sheets' points direct water toward a channel, subsequently proficiently keeping water from remaining along the roof or its gutters. In contrast, flat polyiso sheets are installed on a flat roof and direct water toward the drain (gutter).
Polyiso insulation is much more productive and efficient in a hot and harsh environment. This excellent protection type is best when climate conditions are preferably mild. However, a polyiso tends to be a little weak in a cold environment, although you can get a polyiso to protect your roof even in a cold climate. Of course, the help of a roofing contractor will come in handy here.
The water assimilation pace of polyiso protection is tremendously high; therefore, it's regarded as the most effective material that hinders water intrusion into the roof. It also makes your roof exceed the average lifespan
Before installing any polyiso board, you need to sort out what you need and request it. You can approach this two different ways:
Take the whole Sq. Ft. of the rooftop deck you want to install the polyiso. Separate it by the Sq. Ft. of the board, that is, 4' x 8' or 32 Sq. Ft. then round It to the closest board and add a waste factor ( 10%) and request.
You can precisely spread out how the board will fit on the rooftop deck, check them up, and add waste. This technique requires some time but will be more exact, particularly on more modest positions.
Presently, you know how many polyiso you need per layer; however, you need to sort out the kind of polyiso you will purchase. If the roofing membrane you're utilizing is glued, you will require an iso board with a fiberglass facer. But when your membrane is going to be screwed down, you shouldn't bother with this facer.
NRCA (National Roofing Contractors Association) suggests that TPO installation should be in two layers with several junctures. That is, the edges of the first and second layers should be with a distance of at least 60 degrees.
If you are required to glue your polyiso board, you should consider using one of the glue units available. These packs usually comprise of two dispensable canisters: one of low foam and one of cement. When you combine a hose and firearm, you can use them to shape dots or lines of cement to lay the iso in. This makes the installment spotless and quicker.
This process requires at least three personnel on the side of the roof. That is, you will need two additional labor aside from the person installing the roof. As a top roofing service in New York, we have both labor and materials in place.
It's important always to take your measurement right. It's better to overmeasure than under measure. It might be hard to get the correct measurement in the first measure, but that's the more reason to re-measure to get an almost right size to use for your roof.
Polyiso is one of the most effective approaches you can use to protect your home. Always ensure your polyiso is dry before you think of installation. You should store it in a chill and dry place. Because if a polyiso is wet, it will be harder to install and even require more screws and take more time.
If possible, don't use a wet polyiso on your roof at all; this is to ensure that the polyiso is decent, neat, and protects your roof for a long period.
This is not the only flat roof insulation method. We also have extruded polystyrene (Xps) and Expanded polystyrene (Eps). Now, even though you just learned how to install a polyiso yourself, we don't advise that you do it yourself. The truth, there are certain complexities and information that are available to only a seasoned roofer. And besides, what if polyiso doesn't fit your building?
