Managing Roofing Adhesives in Cold Weather

roofing adhesivesLate fall and early winter is when the Pacific Northwestern chills begin setting in. Can you perform maintenance work on your residential roof during this time? This is an important question because cold weather affects roofing adhesives. Without the right techniques, the adhesives may not dry and create a solid seal.

How Cold Weather Affects Roofing Adhesives

Cold temperatures change an adhesive’s physical properties, causing it to become rigid. This makes the compound unusable, possibly bringing roofing work to a halt. You need adhesives for securing the roof membrane. Continue Reading →

Flat Vs. Sloped Roof for Residential Properties

Flat Vs. Sloped RoofHomeowners often associate flat roofs with commercial roofing. However, a flat roof architecture—while atypical for a home—is also viable for residences. We’ll discuss the difference between a flat vs. sloped roofs and their respective pros and cons.

Flat Roof

A flat roof installation may be cheaper since the total area is usually less than that of a sloped roof. We recommend a flat roof if you contemplate using the area as a part-time living space. This is a trendy option. Some homeowners even go the creative route by covering the roof in soil and grass to promote green living. While this is certainly an option, the roots can burrow into the roof and cause leak-induced damage.

The biggest drawback, though, is a flat roof’s relatively short life expectancy. Flat roofs are typically made from asphalt topped with a gravel-based coating. While fairly inexpensive, the lifespan is only about 10 to 15 years. Other material options include rubber with an elastomeric membrane. This is significantly more expensive but has a lifespan of 40 to 50 years. The warranty, though, may still protect the roof for just 10 to 15 years. Continue Reading →

Shingle And Tile Roofing: Learn How They Differ

shingle and tile roofingMany types of residential roofing are available. Shingle and tile roofing are two common styles. Homeowners, though, tend to use the two terms interchangeably even though they denote different types. We’ll explain the difference and the main characteristics of each one.

Shingle Roofing

Shingles are typically made from asphalt, are rectangular, and overlap one another to keep out water. Shingles are the most common residential roofing type. Homeowners appreciate shingles for their low up-front cost, durability, and waterproof and wind-resistance abilities.

Shingles also reflect sunlight quite well. Also, modern manufacturers have designed shingles to resist fire and algae growth.

Tile Roofing

While Shingles are more popular in the U.S., tiles are more commonplace worldwide. They have also been in use for over a century, pre-dating shingles by several decades. The tiles are made from slate or terra cotta and hang in parallel rows to keep out water.

Tile is heavier than shingle, giving it good strength and superior wind resistance. They also have long life spans, with manufacturer warranties averaging 50 years.

This is also a good style if you appreciate Spanish or Mediterranean architecture.

Which Is Better?

We supply both styles for residential and commercial roofing, but don’t advocate one over the other. While tiles tend to be sturdier, shingles are not that far behind, thanks to modern manufacturing methods. Go with shingles if you want a budget-friendly option. If you’re willing to shell out a bit more for excellent craftsmanship and an old-time look, you can’t go wrong with tile.

Is the Roof to Blame for a Ceiling Leak?

ceiling leakA ceiling leak shouldn’t be confused for a roofing leak. Just because water is emanating from the ceiling does not mean that the roof is the problem. The drip point isn’t always the source of the leak. Water follows the easiest path until it reaches an obstruction or the lowest point. We’ll consider possible sources of a ceiling leak if not from the roof.

Sources of a Ceiling Leak


Clogged drain pipes can cause leaks. If the water appears fresh, then bad piping is likely the culprit. If the water looks dirty, then it’s more likely a residential roof leak. Continue Reading →

Use a Data Warehouse Roof To Protect Your Information

data warehouse roofsMore businesses are beginning to store their data in the cloud. Even so, many still rely on in-house data warehouses for storing their digital information. Businesses need to safeguard their data not just from hackers, but from natural elements as well. A sturdy commercial roof protects your data warehouse from extreme heat and cold.

Why Roof Quality Matters

The roof may directly block sunlight, but the panels may also be collecting heat that causes the temperature to rise inside the data warehouse. Heat is the greatest enemy of anything made up of internal circuit boards. Too much heat can result in condensation buildup inside the circuitry and cause damage. Heat can also melt the capacitor and cause short circuits in motherboards.

Certain roofing materials, such as metal, are also known to collect heat and retain it long after the sun has gone down. This is especially true of darker-colored panels as well as the tar paper beneath. This isn’t to say that these materials are inferior. It’s just that they may not be the best choice for data warehouses and some commercial roofs. Luckily, Bellevue isn’t exactly known for blistering climates, so this isn’t a major concern for businesses in the area. Continue Reading →

Flat Roof Drainage Systems

Flat Roof Drainage SystemsFlat roofs have been around just about as long as sloped roofs. A flat surface, however, means the need exists for a more complex drainage solution. Otherwise, pooling can occur the minute the area experiences a rain spell. Pooling leads to leaks and premature deterioration of the roof membrane. We’ll go over the three primary types of drainage systems for flat roofs and how they work at keeping roof puddles at bay.


Gutters are the typical drainage systems seen on residential roofs. They consist of an open pipe affixed to the edge of the roof and ends with a downspout. Gutters are just as applicable for flat roofs. Plus, they’re also a cost-effective solution since they can be installed without making any structural changes to the roof itself. Continue Reading →

The Benefits of a Butterfly Roof

butterfly roofThinking about rebuilding your entire roof? This is your chance to consider a new design that is equally as efficient as it is visually appealing. One style we recommend is a butterfly roof. It’s a somewhat unconventional design that appeals to some homeowners and even businesses.

What Is a Butterfly Roof?

Butterfly roofs slope inward. This is the opposite of typical roofs; they slope away from the center. Butterfly roofs somewhat resemble a butterfly lifting up its wings, hence the name. This design encompassed a lot of residential roofs in suburban homes during the 1950s. Continue Reading →

Different Types of Roofing Warranty Options

roofing warrantyIt only makes sense to obtain a warranty since roofing is such a big monetary investment. Like insurance, warranties come in various policies. We’ll explain the types of roofing warranty options available for both residential and commercial projects.

Roofing Warranty Types

Labor and Material

As stated in its name, this warranty covers defects associated with the materials and/or workmanship. There is usually a maximum limit on what the manufacturer is liable for.

Materials Only

Pretty self-explanatory. This is essentially a manufacturer’s warranty that covers defects associated with materials. This warranty is usually included at no additional cost to the homeowner. Continue Reading →

DIY Methods for Removing Ice Dams From Roofs

Ice dams on roofsSeattle isn’t exactly blizzard city, but it does see occasional snowfall. With winter still in full swing, you need to watch out for ice dams forming on your roof. Ice accumulation can cause extensive damage for residential and commercial roofs. We’ll lay out a few methods for getting rid of icicles forming on the edge of the roof.

How Ice Dams Form

Ice dams form when water collects on the soffit and gutters and then freezes. Ice dams are bad news because some of the ice can melt and leak into the interior, causing damage to the ceilings, walls, and insulation.

How to Remove Ice Dams from the Roof

Most people remove ice dams using the good ol’ hack-and-slash method. This requires some muscle power, but it’s effective. Simply break apart the ice using a hammer, axe, or icepick. We must stress that while this method works, you also risk damaging the roof panels or shingles if you apply too much force. Some homeowners have even resorted to homemade blow torches. We can’t recommend this for the obvious safety risk.

A viable alternative is to use a roof rake. You can get this nifty tool at your local hardware store. You risk little damage to your roof, and you can remove most of the ice without having to climb a ladder. Continue Reading →

3 Roofing Resolutions for 2017

roofing resolutionsHome remodeling is a common New Year’s resolution. However, we always stress that functional renovations should be given priority over aesthetic changes. With that in mind, why not kick start 2017 with a roofing resolution? This goes for both residential and commercial facilities.

Resolutions for Your Roof

Any roof upgrade begins with an inspection to determine where fixes and modifications can be made. Here are three of the common recommendations we make, based on what we often uncover during an inspection.

1. Total Roof Replacement

Roofs are designed to last anywhere from 20 years to a lifetime. If your roof is well into its golden years, then now may be a good time to replace it. A new residential roof will perform better functionally while also enhancing curb appeal. Perhaps a new tile or wood shake roof will provide a fresh appearance over the existing shingles that are peeling away. Continue Reading →
