Roofing FAQ

Is it just a leak or has your roof reached the end of its serviceable lifespan? When you need roof

replacement, we’ve got the expertise, the materials and the equipment to bring any project into alignment

with your satisfaction. Below is the information you need to help determine if your roof needs replacement

and the basic roofing structure principles we apply to insure proper installation. For a roofing inspection or if

When to Consider Re-Roofing

Leaks

A leak, of course, is the most obvious clue that your roof needs some attention. Leaks can be caused by a

variety of reasons, including ice dams, shingle blow-off or improperly installed or deteriorated flashing.

Don’t just look for a drip coming from the ceiling, though. Signs of moisture also include discolored spots on

the wall, loose wallpaper, peeling paint on the ceiling or a damp smell in a hallway or room. Also remember

that water traveling into your home may take a circuitous route, running down rafters, top plates, studs and

sole plates before reaching your ceiling.

Ice Dams

Repeated exposure to ice dams can damage your home permanently. Build-ups of ice and snow at the

eaves, ice dams are formed when escaping attic heat melts snow at the ridge or peak of the roof. The

meltwater seeps down the roof under the snow and refreezes at the eaves, which are colder. Some of the

trapped water can seep through the roof, damaging shingles, the roof deck, even your home’s interior.

Although ice dams might seem like a roofing problem, they are actually caused by poor attic ventilation. If

ice dams plague your home, consider applying a waterproofing shingle underlayment when you re — roof.

Then be sure to increase ventilation.

Environment

Seasonal and weather changes also play a role in the aging of asphalt roofing shingles. For example,

consider the common situation in which the roof is bathed in the intense heat of the summer sun. On such a

day the rooftop may reach temperatures in excess of 160F. Now imagine a cold front sweeping through

the area, bringing with it the violent thunderstorms that are a common occurrence during the sweltering days

of summer. Almost instantaneously, the rooftop temperature drops 60 — 100F as it’s pounded with a

summer shower. Thermal shocks such as this cause the roof deck beneath to expand and contract, placing a

strain on the shingles. Year after year this process is repeated, resulting in cyclic fatigue of the shingles.

In addition to all of the climatic and external variables that can impact the performance of your roof,

consider the internal factors that negatively influence the performance of roofing shingles. Our experience

has confirmed that an improperly ventilated air space inhibits air movement and under most circumstances

increases moisture content in comparison with properly vented attic air spaces. Heat shortens the shingles’

life and moisture causes deck movement and/or deterioration, which ultimately affects the performance of

shingles.

Other environmental factors such as moisture, pollution and physical effects (roof traffic, hail, snow loads,

tree limbs, etc.) all contribute to the aging and degradation of your roofing shingles.

Update Your Home’s Appearance (and value!)

Even if you’re not experiencing specific problems, you might decide to re — roof your home. Maybe a

neighbor’s re — roofing job has impressed you, or maybe you’re simply trying to give your house a face-lift.

Add a dimensional look to your roof through the use of layering, shadow lines or intricate blends of colors.

Or, achieve the look of natural slate or wood shakes. Thinking about giving your home a make — over? A

new roof from Reeves Home Improvements p rovides an opportunity to give your home a distinctive look,

as well as superior protection.

Roof Structure — Think Integration

A roof is much more than just shingles. When you replace your roof, be aware that it is a system of

integrated parts including:

1.) S hingles

2.) F elt or S hingle U nderlayment

3.) V entilation

4 .) I nsulation

Working in unison, these elements can provide maximum performance and efficiency. Shingles by

themselves may look nice, but without considering the whole package, you could be looking at major roof

or attic problems down the road. A quality roofing system involves the shingles, underlayments and

ventilation products all working together. Day after day, year after year. Decade after decade.

Basic Structure

Most house roofs are gable roofs, consisting of two planes that meet at a central peak and slope down to

the building’s long walls. The triangular sections on the ends are the gables. The hip roof is similar to the

gable roof except that all four sides are sloped. A flat roof generally overhangs the outside walls of the

house. On most homes, the various types of roofs are used in combination.

The major parts of this roof are the:

1.) Ridge

2.) Gable

3.) Dormer

4.) Roof deck

5.) Rake

6.) Eave

7.) Valley

Flashing

The key to waterproofing your home’s roof is flashing. Wherever there is a joint (between roof sections,

Copper, galvanized steel and aluminum are the most common materials used for flashing.

Flashing, if installed correctly, directs streams of water from these points of entry:

1.) Skylights

2.) Chimneys

3.) Vents

4.) Valleys

5.) Eaves

6.) Rakes
