Common Misconceptions about Roofing and Siding

By Joey

Homeowners always ask me whether a certain shingle or siding repels water better than the other. You may be surprised to hear that no matter what you have on your roof or siding, water is still going to find its way below or behind it. We in the construction industry have common sayings; Mother nature will always win, water follows the path of least resistance.

ROOFING

The common misconception about shingles is that they protect your home from water, WRONG.

 

 

Here are the things that shingles are designed for:

  • Ballast in a Windstorm
  • UV Rays Protection
  • Decoration, coloring, and Curb Appeal

When roofing, pay very close attention to the details. The most important detail in roofing is the underlayments, the felting to be exact.

Ballast in a windstorm means that the weight of the shingles protects the underlayments from being blown off in the wind.

The UV radiation protection is the biggest key of shingles. The felting, which is all tar based, if it is affected by the sun’s harmful rays will be ruined and wont repel water any longer. That’s why shingles have small rocks called granules in them. When you get hit by a hail storm and all those rocks get knocked off your shingles, your roof is in serious risk of a shorter life span.

Shingles are meant to make your house look better! Curb appeal is quite important when trying to sell your home. The colors from the shingles can accent your windows and siding.

SIDING

Can you guess what is important in shedding water away from the walls of your house? You guessed it! The underlayment, which can be house wrap, felting paper, or bituminous window wrap. Water will still penetrate past the siding; your last line of defense is the underlayments.

Siding, just like the shingles, help protect your underlayments from the sun’s harmful UV rays and make your home look incredible. The house wrap, felting, and the window wraps can also be ruined by extended exposure to the sun!
