Should You Invest in a White Roof?

white roof, cool roofWhite roofs, also known as cool roofs, are becoming a trend among some Mukilteo businesses. However, this popular commercial roofing type isn’t without its controversy. We’ll explain the pros and cons.

What Is a White Roof?

A white roof is pretty much self-explanatory; it’s a roof with white panels. This is supposed to be an energy-efficient form of facility construction. Think about it: why is it a bad idea to wear black on a hot summer day? The color of night absorbs heat far more than lighter colors. More heat absorption means more heat transfer into the building interior. Lighter roof panels have the opposite effect.

According to studies from the Lawrence Berkeley National Laboratory, white roofs reduce energy use by 20% on a hot day. In metropolitan areas, white roofs also help reduce smog levels by lowering city temperatures. The latter tends to be higher in urban areas due to the mass heat absorption from paved roads.

Four Common Warm Weather Roofing Stressors

warm weather roofing stressorsWith summer here, the sun is going to be looming full force over Mukilteo. The heat can be brutal on roof panels and cause collective damage. We’ll identify typical warm weather roofing stressors and how to minimize their potential wear and tear.

1. UV Rays

Even the sturdiest shingles and panels can dry out due to UV ray exposure over many summers. This leaves sections of the roof with little protection. Cracked shingles are a sign that a replacement is in order. Other signs include curling at the corners and fewer granules on each shingle.

2. Humidity

The Pacific Northwest isn’t the most humid region by a longshot. Nevertheless, summer does mean elevated humidity. If the roof surface has cooler temperatures than the surrounding air, water will condense right on the roof. Summer is the time to consider add-ons, such as ridge or soffit vents. Our other services include vent installations and upgrades. Continue Reading →

Are You Helping the Environment With Green Roofing?

Green roofingGreen homes are a rising trend in Mukilteo. Most people care about the Earth and want to contribute to a sustainable planet. Did you know, though, that correlations exist between the roofing and the environment? Roof care, or the lack of it, determines a home’s degree of carbon footprint.

How the Roof Affects the Environment

America is home to 3,091 landfills. Americans also discard enough trash every day to fill 63,000 garbage trucks. Much of that garbage consists of house-related items, including roofing materials.

Typical residential roofers spend 80% of their time replacing a roof rather than making repairs or installing a new one. Roof replacement means the old roof ends up in the landfill.

This is why roof maintenance is so important from an environmental perspective. Proper care causes the roof to last longer, so that it doesn’t end up as waste well before the end of its lifespan. Continue Reading →

Open Valley Roof Vs. Closed Valley Roof: Know the Difference

open valley roof, closed valley roofInstalling a new roof? Repairing an existing one? The installer may enquire whether you want an open valley roof or closed valley roof. Most homeowners are probably unaware of the difference. We’ll explain how open and closed systems work, so you know which is better for your residential needs.

What Is a Roof Valley?

In a sloped roof, a valley is the section where the different flat areas come together in a V-shape formation. The valley is an integral part of the roof, and the area is prone to leaks, necessitating flashing. The valley is also where water collects when it runs off adjacent sections of the roof.

Open Valley

In an open valley, the valley area is protected by a heavy-gauge aluminum or metal strip, and by a water and ice shield. The point of intersection, though, is uncovered by the uppermost roofing material. Continue Reading →

Does Your Commercial Roof Need a Access Hatch?

Access hatchAlmost no residential roofs have a access hatch. Why, then, do you need one for a commercial roof? Commercial facilities have stricter building codes, thus requiring regular inspections. This includes maintenance of the roof. A hatch provides an easy and safe access point for inspectors and in-house personnel.

Considerations for an Access Hatch

First, you need to determine a size for the hatch. Do you intend to just use the hatch as an access point for staff members? Or do you require a larger opening for transporting large equipment? Warehouses and manufacturing plants tend to require the latter, especially if installing generator or HVAC equipment.

A hatch also requires a built-in ladder or stairs. For smaller single-cover hatches, a fixed ladder usually suffices. For larger hatches and for transferring heavy equipment, the roofer may recommend the installation of ship stairs. Continue Reading →

The Different Types of Metal Roofing Panels

metal roofingMost homeowners are aware of the different types of residential roofing shingles. With respect to metal roofing, though, people often assume there is only one type. Different types of metal roofing panels are available, so they’re just as diverse as shingles. We’ll introduce the different styles of this very durable roofing.

Four Metal Roofing Types

1. Steel Roofing

Steel is an alloy consisting of iron and other elements. Most roof manufacturers make steel panels from recycled material, making this roofing style a sustainable and cost-effective option. Most steel panels are made from either galvanized or weathering steel.

2. Aluminum Roofing

We recommend aluminum panels for coastal homes due to their resistance to salt corrosion. Aluminum is highly reactive to oxygen, which causes the formation of aluminum oxide. This acts as a seal that protects the panels’ inner layer from corrosion. Continue Reading →

Roofing Membrane Parameters for a Commercial Roof

roof membrane parametersCommercial roofing typically consists of flat roofs. This is a sound choice. However, there are many varieties of roofing membranes. Some are higher-quality than others. Your roofer will choose a membrane that’s right for your facility and location. Nevertheless, we recommend that you acquaint yourself with the many roofing membrane parameters.

Rating Parameters for Roofing Membranes

Breaking Strength

Most contractors mechanically fasten membranes to the roof deck. Breaking strength evaluates the membrane’s ability to hold in place in the event of extreme forces, such as strong winds. Continue Reading →

Is Solar Panel Roof Damage Possible?

solar panel roof damageHomeowners may consider home improvements as part of a New Year’s resolution. Some ideas may include the addition of solar panels. Sure, this is a great investment for reducing energy use. However, some people worry about the possibility of solar panels roof damage. Is this a legitimate concern?

How Solar Panels May Damage the Roof

Solar panels won’t damage the roof, assuming that installation is done by a reputable company. Of course, this doesn’t mean damage doesn’t ever happen. One concern is that the weight of the panels can wear the shingles.

The typical solar panel is made from a combination of silicon, wiring, antireflective coating, and mounting hardware. The panels as a whole don’t weigh a whole lot, usually about four pounds per square-foot. Unless the residential roof is already in disrepair, the additional weight will not harm the roof. Continue Reading →

Roof Repair or Recover: Which is Right for Your Commercial Property?

roof repair or recoverCommercial roofs are exceptionally sturdy, but that doesn’t mean they don’t require periodic inspections. Usually, when the roof requires servicing, the inspector will recommend a roof repair or recover.

Roof Repair and Recover Explained

A roof repair is pretty straightforward. However, hardly anyone has ever heard of a roof recover. Here’s the difference at a glance.

Roof Repair

We may recommend a roof repair due to the presence of minor damage that doesn’t warrant an entire roof replacement. A repair is usually the best option when the membrane is still in good shape and has not exceeded its life expectation. Repairs may include minor fixes, such as sealing areas with worn or exposed flashing. Continue Reading →

Understanding Fire-Resistant Roofing

Fire-Resistant RoofingMost roofing materials are fire-resistant. We must emphasize that being fire-resistant does NOT equate to being fire-proof. Roofs can and do catch fire. We’ll explain the meaning of fire-resistant roofing and how it protects homes.

How Do Shingles Reduce House Fires?

Fiberglass is the most common shingle type for residential roofs. Fiberglass, as well as some cedar shingles, have a class-A in fire rating. This does not mean the shingle does not catch fire. A class-A rating means the material will hold together under the flame. The shingle will not blow off and create flying embers that could cause the fire to spread. Also, it will not crack under the heat or create an opening that can expose the attic interior to the flames. Continue Reading →
