Q: I’m thinking about roof replacement but I also need to increase my home’s energy
efficiency. Can a new roof help lower utility bills, and what energy-efficient roofing
systems are important for an efficient home?

**A: **While [window replacement](https://mycoastalwindows.com/windows/) is one 
of the best ways to lower utility bills, homeowners often forget that [roof replacement](https://mycoastalwindows.com/roofing/)
can lower energy bills as well.

## The roof is designed to work as a system to:

 1. Protect the home from the elements.
 2. Prevent ice dams in the winter.
 3. Save energy and money on your energy bills for a lifetime.

## The Components of a Roofing System: Roofing Materials List

The diagram below shows the parts of energy-efficient roofing systems along with
roofing materials that can impact home performance.

## Roofing Shingles

The shingles are on the first line of defense against the elements. Without durable
and lifetime shingles in place, rain, snow, and wind will easily make their way 
into the attic space. When the attic becomes too hot or too cold, it quickly causes
utility bills to rise by causing the HVAC system to over-perform.

The color of the shingles can also make a difference in energy bills. According 
to Energy Star, Americans spend $40 billion per year on air conditioning. It accounts
for 1/6th of all the electricity-generating in the country.

Shingles with anti-reflecting properties can decrease energy bills in the summer
between 10% to 15%. Choosing a lighter color shingle can help reflect heat during
the hottest months. Despite your choice of shingle color, this barrier will block
out elements that can otherwise increase energy bills or damage the home.

## Roof deck protection

This product helps to further seal the home’s envelope while adding a second layer
of protection from the elements. Most importantly, it works to block water infiltration
that can cause the roof to fail sooner than later.

A failing roof can lead to higher energy bills. Excess water can damage attic insulation
and rot out areas of the roof, which provides a pathway for energy to easily escape.
With quality roof deck protection, wind-driven rains and strong storms won’t negatively
impact your roofing or energy bills down the road.

### Ventilation

Roof ventilation is an essential component of energy efficient roofing systems. 
When it comes to all of the roofing materials, ventilation might make the biggest
impact on your monthly energy bills.

The goal is to keep the attic close to the outdoor temperature. When airflow is 
not reaching the attic space, it can easily overheat in the summer. Adequate ventilation
consisting of intake and outtake vents circulates air and keeps the HVAC system 
from working too hard to cool the home.

During the winter, attic ventilation helps keep the roof cool to [prevent ice dams](https://mycoastalwindows.com/ice-dam-guide/).
While ice dams might not reflect on utility bills, it will certainly cost you money
if it damages the roof or the gutter system.

Home Advisor warns that too much ventilation can cause problems such as leaking 
or even blowouts during a hurricane. The right amount of ventilation is calculated
by a ratio which is 1:300. This means for every 300 square feet of living space,
you need 1 square foot of ventilation.

in the home:
