All about Roofing

The function of roofs is to cover the house. This however is not the end of the things that one must think of when getting roofing. They should know the type, style and cost.

Asphalt shingles: Over 75% of American roofs have asphalt shingles due to low cost, ease of installation, and resiliency. Unfortunately, asphalt shingles have a low insulative value and a shorter lifespan than many other roofing materials available today. They are also made from petroleum products and are not usually recyclable because of the layer of fiberglass added to the shingles. Standard asphalt shingles come in a variety of colors, longevity options, and price points and are always going to be your cheapest option for your roof, but they have the worst environmental track record.

House Style: Can be used for any architectural style.

Cost: $50 to $150 per square (10 x 10 area = 100 square feet = 1 square)

Life Span: 15 to 30 years

Green Factor: Least-green roofing option.

It is not enough to just know the type of roof. It is also equally important that you know the components of a roof system for instance the sheathing and structure.

Roof system components

  • All steep-slope roof systems (i.e., roofs with slopes of 25 percent or more) have five basic components
  • Roof covering: shingles, tile, slate or metal and underlayment that protect the sheathing from weather.
  • Sheathing: boards or sheet material that are fastened to roof rafters to cover a house or building.
  • Roof structure: rafters and trusses constructed to support the sheathing.
  • Flashing: sheet metal or other material installed into a roof system’s various joints and valleys to prevent water seepage.
  • Drainage: a roof system’s design features, such as shape, slope and layout that affect its ability to shed water.

So when was the last time you inspected your roof? Do not wait until things get bad to do so. Inspection should be done inside out. There are things to check for on the inside like a sagging rook deck and on the outside like a rooting or algae.

┬áBut inspecting your roof regularly and making little fixes as needed can prevent some costly repairs down the road — and keep those raindrops from falling on your head. There’s another benefit, too: Keeping your roof in good condition will also be a big plus if you decide to sell your home.

Here are four things to look for on the inside:

1) Places where the roof deck is sagging

2) Signs of water damage or leaking

3) Dark spots and trails

4) Outside light showing through the roof.

When you take a look at the exterior of the roof, pay attention to such things as damaged flashing, missing shingles, curling, blistering, buckling, rotting and algae growth (which occurs most often in humid climates and appears as dark or greenish stains).
