Category Archives for "Modified Bitumen Roofing"
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).

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.
It was a pleasure dealing with flatroofs.ie they provide a highly professional and considerate service. I have received a number of comments regarding the works from neighbours.
They all asked who was carrying the work and for your contact details.
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.
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.
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.
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.

A flat roof is a roof which is almost level in contrast to the many types of sloped roofs. The slope of a roof is also known as its pitch and flat roofs have to be up to approximately 10 - 15°, to allow for rain to flow to the gutters.
