New Roofs in Cambridge: To Roof Or Not To Roof? That Is The Question!

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.

Trust a Roofing Professional

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.

Built Up Roofs
(BUR)

Built Up Roofs (BUR)

Built Up Roofs (BUR), often referred to as tar and gravel roofs, are one of the most common low slope and flat roofs. Multiple layers of roofing materials are sandwiched between layers of bonding materials, the most common being bitumen. Gravel is applied to hold down the roofing material and to offer UV protection.

Thermoplastic Polyvinyl Chloride (PVC) Roofing

Thermoplastic Roofing (PVC)

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.

Modified
Bitumen

Modified Bitumen

Modified Bitumen is an asphalt-based roofing system designed for flat and low-slope roofs. Synthetic polymers are added to create elasticity especially in cold temperatures. It has numerous surface options and colours. It can be installed by torching or by rolling on self-adhering sheets. It has a proven record of performance and waterproofing.

Thermoplastic Roofing (TPO)

Thermoplastic Polyolefin Roofing (TPO) membrane has become a very popular roofing material consisting of single ply reinforced fabric and rubber. It is considered an environmentally safe, "green" product which is installed using fasteners and plates along the edges. TPO can be fully adhered to a base. Adjoining sheets are overlapped, fastened and hot-air welded which makes it highly resistant to wind and weather factors.

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.
