Choosing a Flat Roofing System

The best Flat Roofing System

Flat roofs are found on commercial buildings and residential buildings, but this does not mean you cannot have a flat roof constructed for any building.

There are several things to consider when choosing a flat roof, such as the materials, weather, and maintenance. Here are a few advantages and disadvantages of constructing a flat roof.

The Advantages of Flat Roofing

There are many people who prefer a flat roofing system over shingles or a tile roofing system. Here are several benefits of choosing a flat roof for your home or business.

  • Easy Construction: It is easy to construct a flat roof, so you do not have to worry about your contractors running into an issue with the project.
  • Flat Roofs Are Durable: If durability is important to you, then a flat roof is just the system for you. A flat roof is water resistant, so you do not have to worry about water damage. If you are using a flat concrete roof, then you are using a roofing system that holds up against heavy winds. The risk of a fallout decreases when you opt for a flat roof on your home or business.
  • Repair if Possible: If there is a problem, it is just as easy to repair the flat roof as it is to construct it. The cost to repair or re-coat a flat roof is affordable compared to other roofing systems. You can have your flat roof fixed without breaking the bank or putting a lot of stress on yourself.
  • Easy To Clean: A flat roof is easier to reach than most systems, which makes the maintenance easy. You want to remove algae, mold, and stains from your roof regularly to prevent debris from building up. Pressure washing is the best way to clean your flat roof without damaging it, especially if you have a flat concrete roof.

The Disadvantages of Flat Roofing in Leinster

It is important to know the cons of a flat roofing so you can figure out if it is right for your home or business. Here are the disadvantages of choosing a flat roof for your home or business.

  • Lack of Drainage: The biggest disadvantage of a flat roof is the lack of drainage, and this is why it is important to check your roof regularly. If you do not inspect it regularly, your drains may become clogged with snow and water. You want to clean out the drains as needed and be sure to use a waterproof seal regularly to prevent leaks. Remember, there are no slopes for the water or snow to slide down.
  • Debris and Dirt Build Up: Snow and water are not the only things that can cause problems on a flat roof. Leaves, twigs, dirt and other debris can also clog up the drain, and this leads to snow and water not draining properly. You can avoid a clogged drain by regularly inspecting and cleaning the dirt and debris off your roof.
  • Limited Roofing Materials: The majority of flat roofs use rolled roofing materials, which include TPO, EPDM, rubber, and bitumen. The materials are inexpensive but only last from ten to 15 years. There are alternatives, such as using rubber shingles with rolled rubber roofing, but they are more expensive and it is unknown how long the materials will last.

There are home or business owners who use flat roofing for years, and there are some home or business owners who realize it is not right for them. It is best to go over the advantages and disadvantages of flat roofing and decide if it is right for your home or business. We have put together a guide to flat roofing contractors

Modified Bitumen Flat Roof

Modified Bitumen Flat Roof

A Modified Bitumen is a key element in any built-up roof.

This type of roofing system was developed in Europe during the sixties and later introduced in the U.S. in the early seventies. Modified refers to the addition of plastic or rubber-based polymeric binders to the asphalt or “bitumen” to improve its roofing performance and durability. Modified Bitumen Flat Roofs are usually assembled using one, two or three plies.

The Modified Bitumen Membrane is made up of multiple layers in what is essentially a “factory assembled” built-up roof. During the roofing manufacturing process, several coats or laminations of modified bitumen are reinforced with a woven fiberglass, or polyester fabric reinforcing mat or a combination of both. They are then finished with either a smooth or granular top surface.

The Granular type comes in different colors. The smooth surface type is then coated with either an aluminum or white surfacing on site. The coatings are used to deflect the damage from ultra-violet rays from the sun as well as keeping the roof surface cooler.

Modified Bitumen Roofs exhibit many characteristics of a built-up roof (BUR), yet affords the ease of application on a single-ply roof. This offers various specifications which allow for multiple plies, which provide redundancy and exceptional resistance to heavy traffic, punctures and tears. Modified Bitumen membranes also have low-temperature flexibility and are resistant to membrane fatigue(break down).

There are two types of Modified Bitumen Systems

  • APP (Atactic Polypropylene) roofs are applied using a heat-welded method. The top surface comes in either smooth or granular. The consistency and uniformity of the factory produced sheet results in a membrane that has greater stability and flexibility than that of a laminated built-up roof system.
  • SBS (Butadiene Styrene) roofs are usually applied using hot asphalt, bonding adhesives, heat welding or heat activated self-adhesives. The top surface is a mineral granular of choice of colors. It has the benefits of a built-up redundant system with the quality of a factory single ply membrane.

TPO Flat Roofing Contractors

TPO Flat Roofing Contractors

TPO Flat Roofing

TPO is an excellent roofing system for any climate. TPO, it is said is an advancement and a great improvement to traditional flat roofs that are being explored today. The seams of TPO roofs are welded instead of glued. They are less likely to separate when heated and consistent environmental changes.

The Manufacturer certify the flat roof contractors to install the membrane and in turn honor the warranty. A TPO flat roof material gave a white surface that reflects ultraviolet light and keeps the structure cooler than other options.

Because the system is relatively new, revisions and improvements are happening everyday. This requires flat roof repair contractors addressing shrinkage caused by prolonged exposure to UV rays.

They cause stress on flashing and seams. The warranty on TPO roof systems is 15 to 20 years. The welds of both hand-held and walk-behind welding must be checked. Welding that does not take, must be patched or replaced.

Long and short seams require different welds. A lack of uniformity can cause seams to fail and leaks on the roof. Commercial skylights for flat roofs cannot be welded with walk-behind welders used for long seams.

Short seams are needed for A/C units, drains, vents, and skylights. These areas are welded with a hand-held heat gun. The heat difference between the long and short seams becomes an issue.

Heat-welded seams must be correctly calibrated throughout the day of flat roof installation. The quality of a welded seam is affected by wind, cold, and humid weather conditions. A tool is used to check the seam quality to ensure the welds take.

There are many different types of Flat Roofs and we have listed the Pros and Cons of each below

Newer and newer flat roofing materials are appearing yearly. They wear better than older material and made with better technologies than before.

Domestic/Homeowners and Commercial business can choose among four kinds of flat roofs.

All 4 types of flat roofing systems can cost €250 to €350 per/square foot, prices do vary according to region and size of the roof. Flat roofs usually come with a 10 to 25 year warranty but the roofs can last up to 30 years if properly installed and maintained.

Built-Up Roof or Hot Tar flat roofing

The traditional hot tar and gravel roof is built from three or more plies of waterproof material alternated with hot tar and ballasted by a layer of smooth river stone. Once made of tar paper, these types of roofs gradually are using more-advanced materials such as fiberglass membranes.

  • Pros: Gravel is an excellent fire retardant. Attractive for windows and decks that overlook the roof. It’s the cheapest of the four roof varieties.
  • Cons: Very heavy. Joists sometimes have to be strengthened. Smelly and messy to install. Installation’s not recommended for occupied homes. It’s not a DIY installation job, and it is hard to find the source of leaks. The gravel has been known to clog gutters.

Heated Modified Bitumen

A single-ply rolled roof similar to ice-and-water shield, but impregnated with a mineral-based wear surface. Torch-down systems involve heating the adhesive as the material is unrolled. Newer peel-and-stick systems are safer and easier.

  • Pros: Peel-and-stick material can be installed easily. Its light-colored mineral surface reflects heat and cuts energy bills. Its price is in the middle of the pack.
  • Cons: Torch-down application is a fire hazard, and not recommended for occupied buildings. It has been know  to scuff and tear rubber-membrane roofs.

Rubber Membrane Flat Roofing

EPDM (short for ethylene propylene diene monomer) is a true rubber. The durable material resembles an inner tube, but it’s engineered to resist damage from sunlight. EPDM can be mechanically anchored with fasteners, ballasted with stone, or glued in place.

  • Pros: Homeowner-friendly installation. The material’s relatively light yet highly resistant to scuffs and tears. Leaks are easy to patch.
  • Cons: The standard black material absorbs heat, and light-colored coatings (recommended in warm climates) add 30% or more to the cost. Even the black version, though, costs more than BUR or modified bitumen. It’s also more vulnerable to punctures than other choices.
