Metal roofing in Concord and Charlotte NC, an overview

Metal roofing has been on the rise in recent times. This article gives an overview of metal roofing, and its benefits to owners of buildings in Charlotte and Concord, NC.

Metal roof

In zinc, steel or copper, sheets, rolled metal, or plates, metal roofing is becoming more and more popular thanks in particular to relatively attractive prices, excellent durability, and above all, great maneuverability. Until recently, confined to the roofing of industrial and agricultural buildings and annexes, the metal roof is also beginning to impose itself in the residential sector. 

The metal roof, a modern and design roof covering

Far from being reserved for covering industrial or agricultural buildings, metal roofing is increasingly used in private houses. It is in the form of sheets of rolled metal or corrugated or ribbed which have the appearance of conventional tiles. Metal panels can be installed on most pitched roofs. Very design, they are appreciated on contemporary houses or architects.

The materials used can be copper, zinc, aluminium, steel. The panels consist of two sheets of galvanized metal coated with several protective layers. This material is both very durable (50 to 100 years) and very light (10 times more than clay tiles). The products are offered in a wide range of styles and colors, which allows you to completely personalize your home. Some roof panels are supplied with an attached layer of insulation (polystyrene or mineral fibers).

Various materials that require good insulation

The metal is fixed to the roof by means of a wooden frame or a cement mortar plinth. The plates are connected to each other by cleats, clips, or by folding in order to prevent water infiltration. A condensation regulator felt can be placed under the cover.

Zinc has a natural patina under the effect of humidity, which makes it even more waterproof. However, this material should be avoided when using an oil-fired boiler or when copper, steel or cement are present. To avoid condensation, a ventilated cover can be installed, with air circulation between the zinc and the insulation. There are photovoltaic panels specially designed for zinc roofs.

Steel tends to rust, so it needs to be protected with lacquer, zinc, or replaced with stainless steel. Copper turns verdigris over time, which also serves as protection. Aluminium being sensitive to pollution, it should be avoided near major traffic axes.

Heating costs are reduced if care has been taken to properly insulate the attic and remedy thermal bridges. The BUR flat roof type can achieve a very high level of thermal performance (R = 11.50) with a low incidence of temperature and hydrometry variations.

A roof made to withstand bad weather

The panels with corrugated profile ensure good evacuation of condensation and optimal air circulation.

A metal roof is designed to withstand fire and wind up to 150 km/h. It is not very sensitive to stains and mold. Traditionally used in regions with a harsh climate in winter, this material is resistant to all types of weather (hail, snow) and to large temperature variations. In regions with significant periods of snowfall, it is advisable to install snow hooks or snow guards and a roof underlay. The installation of a cold roof with double ventilation may be recommended.

Metal roofs are, in theory, totally recyclable.

The main disadvantage of a metal roof can be noise in bad weather. Good insulation can remedy this.

A metal treated with a reflective coating returns most of the heat absorbed. The temperature in the attic can thus be reduced by 8% in hot weather.

An inexpensive and very durable roof

The installation of metal tiles is quick and therefore inexpensive. This material offers the best value for money over time. Calling on a professional is essential for neat finishes and a perfectly waterproof roof. An annual inspection visit is recommended to check the condition of the seals and plates. In the event of a localized surface problem, a specific touch-up paint can be applied.

Prices vary depending on the material: around 17 $/m² for metal tiles, 20 to 40 $/ m² for steel, 40 to 80 $/m²for zinc. Financial aid is possible within the framework of insulation work. As with all roofing work, you must first check with the town hall to find out about the legal constraints in your area.
