Hi all

Long Run Metal Roofing and Asphalt Shingle are the two major roofing materials for our new homes.

I am going to describe the pros and cons of these materials.

 

ASPHALT SHINGLE

Advantages
-Cheaper to install than Long Ran Metal Roofing
-Easy & Quick Installation → Shorten your new home construction period
-Solid plywood underlay provides strength to the building and weathertightness
-Quiet → Not noisy when rain hitting the roof

-Dents to be unlikely to happen

-Low Maintenance

-Raccoons, Rodents, Pests, and Wild Animals Proof → No gap between each asphalt tile and plywood underlay does not allow them to enter inside the roof

(Asphalt Shingle Construction)

Disadvantage
-Not highly eco friendly. Asphalt is a semi-solid form of petroleum.
-Can be damaged in extremely cold weather → does not really matter in mild climate in Auckland

Metal Long Run Roofing

Advantages
-Minimum Roof Angle 3-5 Degree → help to keep the roof height low to comply with Building Height Restriction in some cases
-Moss- and Fungus-Proof
-Ecofriendly. Can be recycled

-Fire Resistance

Disadvantages
-Easy to be scratched → need coating on the scratched part otherwise rust may happens
-Easy to be dent → Hard to avoid dents during construction when builders and roofers need to move on the roof
-More expensive to install than Asphalt Shingle
-Little Noisy → Rain hitting the roof or the expansion and contraction of metal roof panels can create noise on the metal roof

I love architecture and design so much that I have been to so many buildings and places around the world such as Sydney Opera House in Sydney, CCTV building in Beijing, Empire State Building in New York, Royal Palace in Bangkok, Houryu-Ji in Nara, etc. However, the residential building attracts me the most. For nearly 10 years I have visited heaps of local and historical homes around New Zealand which I feel the builders’ great workmanship as well as occupants’ life.

From this experience my aim is to design and provide the comfortable and affordable houses with the spirit of Japanese workmanship that people enjoy and improve their quality of life.

In this blog I write my everyday experience of work to show what is a designer’s work and how it goes at Japan Homes.
