What is the longest-lasting flat roof?
Flat roof installation in Texas is common for commercial buildings, perhaps because most commercial structures are large. Thus, a pitched roof would be a target of high winds here in West Texas, whereas a flat roof will be under the wind’s aim. Therefore, more commercial building owners see a flat roof installation when it’s time to get a roof replacement.
Choosing the type of material that you want to be used for your flat roof installation is a little more detailed than changing brands of coffee for the office. This is something that takes a lot of research and thought and examine your budget. Not just your budget for the flat roof installation job but going forward with maintenance and repairs too.
There 100s of 1000s options on the market, so your first decision is to choose a flat roof contractor that knows commercial buildings and the pros and cons of each material that is available. Ask each roofing contractor you interview about the maintenance, the lifespan, and the final cost for a flat roof installation. Three of the most common materials are:
A popular material for flat roof installation and considered being the best may many commercial building owners and roofing contractors. It is an inexpensive option with a lifespan between ten and twenty years. This white-coat roofing is just as energy efficient as a PVC coated roof but requires less maintenance than an EPDM coated roof. With heat-welded seams, this material for flat roof installation isn’t as likely to leak.
For a low-sloped flat roof installation job, Built-Up Roofing, referred to as BUR, is the most common. Composed with layers of reinforcing fabric alternating with bitumen, then finished with an aggregate of gravel or stone as the final layer. BUR flat roof installation is preferred because of its continuous sealed surface minimizes possible problems with leaks.
Modified Bitumen Roof
Modified bitumen flat roof installation is the budget-friendly choice, making it the one that stands out to commercial building owners. The base is an asphalt membrane susceptible to blistering and cracking in harsh climates, giving it only a ten to fifteen years lifespan. Even with a lower lifespan than its counterparts, the price point for flat roof installation makes it the first choice for many businesses.
What is the best material for a flat roof?
Of the flat roof installation materials that we’ve just reviewed, TPO would be the best in the opinion of most flat roof installation roofing contractors. It is easy to install, priced reasonably for any budget, maintenance and upkeep are easy and inexpensive, and the white coating is an energy saver.
How thick should flat roof insulation be?
Polyisocyanurate is a rigid insulation board available in thicknesses between 1” to 4” and is made of closed-cell foam. It comes in flat panels that are usually installed on roofs with a low slope with a guttering system. Or available in tapered panels for a roof with an angle or slop that directs water toward a drain, keeping water from standing in corners. Both types of Polyisocyanurate insulation board comes in 4’ x 4’ boards or 4’ x 8’ boards. Not only is this good for the flat roof installation process, but they can use it on walls as well as flat roof installation jobs, making it a popular choice for contractors.
How do you waterproof a flat roof?
One common issue among all commercial flat roof installation jobs is they all experienced standing water in many places, especially corners. Blocked drains or sagging areas of the roof can cause this. If not addressed and we leave the water to stand in these areas, it can damage the protective membrane, and eventually the roofing underneath.
There a few factors to be considered when approaching a waterproofing process for a flat roof: roof size, structure type, climate, and environment. With those factors in mind, the three main choices in waterproofing a flat roof are:
- Reinforced bitumen membranes – This flat roof installation of waterproofing uses 2 to 3 layers bitumen across the complete flat roof surface that is combined with a polyester carrier to create a waterproof material.
- Liquid waterproofing – This flat roof installation waterproofing uses a special type of weatherproof coating that can be used on many roofing and can last up to 40 years with proper flat roof installation steps followed and proper maintenance afterward.
- Single ply membranes – This is the more common waterproofing for a commercial flat roof installation job. It comes in sheets that can be installed to fit the whole roof and are attached by plastic fasteners screwed into the membrane, attaching it to the roof deck. A stone ballast is placed on top and fastened to keep them in place. Adhesion is then used to ensure the single ply membrane and the insulation are attached securely.
Do you need to vent a flat roof?
The purpose of ventilating a flat roof is to allow circulation in the property. This is beneficial for residential buildings, but not required for commercial structures. For the use of thermal insulation installed below the decking, we must install ventilation on the underside, following the proper flat roof installation instructions.
With the different choices in materials for flat roof installation and the insulation choices, choosing an experienced flat roof contractor is the first step that needs to be made. We always recommend interviewing several is always to compare pricing, references, and most of all guarantees and warranty.
