I have been arguing with other builders and roof experts which roofing system is the most beautiful, They all have different opinions or rather tastes and preferences. This article is inspired by them!
Here is all you need to know about roofing systems and factors to consider when choosing the type of roofing, but before that
The roof is the covering on the uppermost part of a building or shelter which provides protection from animals and weather, notably rain or snow, but also heat, wind and sunlight. Roofing also denotes the framework that supports that covering.
Roof systems and materials generally are divided into
- Low pitched roofs.
- High pitched roofs.
-Low pitched roofing includes water impermeable, or weatherproof, types of roof membranes installed on slopes less than or equal to 15°
-High pitched roofing includes water shedding types of roof coverings installed on slopes exceeding 15°
TYPES OF PITCHED ROOFS
There are five types of low slope roof membranes or systems.
- Built-up roof (BUR) membranes
- Metal panel roof systems for low-slope applications
- Polymer-modified bitumen sheet membranes
- Single-ply membranes
- Thermoplastic membranes (e.g., PVC, TPO)
- Thermoset membranes (e.g., EPDM)
- Spray polyurethane foam-based (SPF) roof systems
Most low-pitched roof membranes have three principal components:
- Weatherproofing layer or layers — the weatherproofing component is the most important element because it keeps water from entering a roof assembly.
- Reinforcement — reinforcement adds strength, puncture resistance and dimensional stability to a membrane.
- Surfacing — surfacing is the component that protects the weatherproofing and reinforcement from sunlight and weather. Some surfacings provide other benefits such as increased fire resistance, improved traffic and hail resistance, and increased solar reflectivity.
With some roof membranes, a component may perform more than one function.
There are divisions of high pitched roof coverings.
- Asphalt shingles
- Clay tile and concrete tile
- Metal roof systems for steep-slope applications
- Wood shakes and wood shingles
Steep-slope roof systems typically are composed of individual pieces or components installed in shingle fashion. Steep-slope roof assemblies typically consist of three primary parts:
- Roof deck — a roof deck is the structural substrate and usually is a wood-based material such as plywood or oriented strand board (OSB).
- Underlayment — underlayment provides temporary protection until a roof covering is installed and provides a secondary weatherproofing barrier. Sometimes underlayment is referred to as “felt” or “paper.”
- Roof covering — the roof covering is the external water shedding material.
