Not a lot of amateurs will tackle a flat roof project, whether it’s a garage or a factory. Flat roofs require specialized knowledge, equipment and skills. These are particularly difficult for the homeowner to tackle. There are issues with flashing, seams, vents and ridges. Also, completing the drains can be difficult. For these reasons, it is recommended that professionals complete your flat roof. However, many amateurs will tackle a shingle roof. This is often triggered by a leak or when the owner's insurance company recommends action.
Some homeowners believe that to shingle a roof, all you need to do is to buy some shingles and nail them on the roof. However, a great deal has changed in the shingling industry. Old shingles have to be removed and disposed of in an environmentally safe manner. Any rotten roof sheathing needs to be replaced and ice and water shield, felt, and flashing installed. At the same time, the peaks and valleys need to be completed and proper ventilation installed.
In addition to shingles below, we present a few of the roofing systems from which you, the owner, may need to choose.
BUR (Tar and gravel)
EPDM, TPO, PVC
ProSeal (RPW) systems

Thermoplastic Polyvinyl Chloride (PVC) Roofing sheets are produced by rolling, spread coating or extruding and are often reinforced. Desired properties and flexibilities are achieved through additives. The seams are sealed by chemical or heat welding and are available in many colours with grey and white being the most common.

EPDM (Ethylene Propylene Diene Terpolymer) is a synthetic rubber membrane which is extremely durable. Available in either black or white, it is available is various thicknesses and widths. It can be installed mechanically adhered, fully adhered or ballasted. The seams can be sealed with liquid adhesives or specially formulated tapes. It can be used for waterproofing and some specific kinds of EPDM for ponds. It has become the standard for roof-top gardens.
