What are the available decking materials used on roofs to receive IKO shingles?

The recommended materials for decking are Tongued & Grooved (T&G) boards and Oriented Strand Boards (OSB). In order to save on costs locally manufactured lamiboards (from recycled tetra pak material) can also be used

What is the required thickness and sizes for the decking material?

The recommended thickness for the OSB and Lamiboards boards is 10mm and they come in 8 x 4ft. The thickness recommended for the T&G is 20mm

What is the spacing for the roof structure support?

The trusses should be 1200mm c/c; rafters should be 600mm c/c and battens at 300 mm

Which is the minimum slope that would require underlayment?

Water falling on roofs need to roll down fast enough and avoid any stagnation or reverse flow as this would reach the decking material underneath thereby causing leakages. To eradicate this problem, underlayment is recommended for pitches below 18 degrees

A few manufactures that were in the shingle business in the 1950’s among them being IKO Canada and CertainTeed used this technology. However as technology advanced in 1970 a law was passed to ensure that all shingles produced had a fiber-glass reinforcement. It is the old and outdated technology that competing firms representing manufactures who joined the industry in the late 1970’s are using to scare off potential clients interested in IKO shingles. These competitors are simply driven by the need to maintain a monopoly in the supply of roofing shingles in the industry

  • Fire and Wind Resistance. IKO shingles are manufactured to resist external fire and flammability standards, and carry Class A, B or C fire ratings, with Class A providing the greatest fire resistance. In addition, IKO shingles carry a "wind resistance" label because they have been manufactured and tested to demonstrate great resistance in high-wind locations.

What common terms will I come across when using IKO shingles?

  • Asphalt: A bituminous waterproofing agent applied to roofing materials during manufacture.
  • Deck: The structural surface to which the roofing or waterproofing system is applied.
  • Flashing: Pieces of metal or roll roofing used to prevent seepage of water into a building around any intersection or projection in a roof, such as vent pipes, chimneys, adjoining walls, dormers and valleys.
  • Granules: Ceramic-coated colored crushed rock that is applied to the exposed surface of the shingles. These granules are eco-friendly and hence water can be harvested for domestic use. They also ensure that the shingles do not fade or change colour.
  • Slope: The incline of a roof expressed either in percent or in the number of vertical units of rise per horizontal unit of run.
  • Laminated Shingles: These shingles have more than one layer of tabs to create extra thickness. They are often referred to as three-dimensional or architectural shingles because they create visual depth on a roof and impart a custom look.
  • Membrane: A roof covering or waterproofing layer whose primary function is the exclusion of water.
  • Pitch: The degree of roof incline or slope expressed as the ratio of the rise, in feet, to the span, in feet
  • Re-covering: The process of covering an existing roofing system with a new roofing system.
  • Re-roofing: The practice of removing an existing roofing system and replacing it with a new roofing system.
  • Ridge: The uppermost, horizontal external angle formed by the intersection of two sloping roof planes.

FAQs about Atactic-Polypropylene (APP) Modified Bituminous Waterproofing Membrane

What is APP modified bituminous waterproofing membrane?

APP stands for Atactic Polypropylene which is a waterproofing membrane manufactured from modified bitumen with the addition of plastomers. The membranes can have fiberglass or polyester as reinforcement.

Why choose APP membranes for your waterproofing job?

APP modified bituminous membrane prevents penetration of water into structures thereby eliminating leakages. In steel reinforced concrete, water causes corrosion of the steel thereby compromising the load bearing capacity of the structure. Constantly wet concrete facilitates thriving of molds, moss and harmful bacteriTherefore keeping surfaces properly drained creates a healthy environment.

What is the purpose of bituminous primer in application of APP membrane?

Bituminous primer cleans the surface by eliminating dust and soil particles thus improving adherence between the APP membrane and substrate.

How long will APP membrane last?

Properly selected and installed APP membranes will maintain good performance for the useful lifetime of the building.

Does the APP membrane get damaged on exposure to sunlight?

APP modified bituminous membranes with mineral granules are resistant to ultra violet (UV) rays from the sun. The APP membranes without surface mineral granules need to be covered with an additional screed, concrete/interlocking tiles or gravel.

Where can you apply APP membranes?

All areas where water comes into contact with critical areas of a building. These include concrete flat roofs, low pitched roofs, foundation walls and wet areas. APP membranes are also used in ground structures such as water tanks, artificial ponds, pools, retaining walls and car parks.

How do you apply APP Membranes to surfaces?

APP membranes are laid by torch-on application. A flame contact causes melting on the surface of the membrane which is then pressed to the substrate with overlaps from adjoining membranes tightly bonded.

Which side of the APP membrane is stuck on the surface?

For plain APP membranes, any of the sides can stick on the surface while those with mineral granules; the outer part of the roll is the one that is stuck on the substrate.

Do I get any warranty on APP membranes?

APP modified membranes come with varying product warranty depending on the type suitable for the job. After application, we issue a 10 year workmanship warranty.

How do you store or transport APP membranes?

APP membranes should be stored in an upright position and when being transported, handling should be maintained in the same position and also avoid stacking any materials on the rolls. Always ensure they are kept away from heat sources and ultra violet rays.

How do I avoid damages on the surface applied with APP membranes?

Any sharp objects or membrane puncturing operations should be kept out of the application surface in order to eliminate leakages.

What can I do to enhance good performance of APP membranes on flat roofs?

You can improve the performance of APP membranes on flat roofs by:
  • Ensuring that manufacturer’s application instructions are followed during installation.
  • Maintain adequate screed slope to outlets.
  • Make regular cleaning of roof surfaces especially after the rains. Unclog down pipes, gutters and drains.
  • Avoid unnecessary roof-top traffic.
  • If you allow equipment servicemen to go to the roof, advise them to be careful.
  • Do not allow service personnel to make penetration into the roof; these to be made by a professional roofing contractor.
  • Keep APP membrane surfaces free from reactive chemicals.
