The Effects of Ponding Water on a Flat Roof in South Everett

Ponding Water on a Flat RoofPonding water can occur on all roof types. This can lead to multiple issues, ranging from leaks to mold growth. Ponding water on a flat roof is especially commonplace. We’ll discuss why this is so and what you can do to minimize water buildup.

What Causes Ponding Water on a Flat Roof?

Ponding water is defined as a puddle that remains on a roof for more than 48 hours. Ponding is typical on commercial roofs, since these tend to have flat surfaces, unlike residential roofs with a sharp slope.

There are two main culprits of ponding water on a commercial roof: building degradation and deck deflection.

Building Degradation

Flat roofs have multiple layers of hot asphalt, roofing paper, and gravel. The gravel is the outermost layer. This is also the part that withers over the years from UV ray exposure. The eroded gravel leads to a recessed section that enables water accumulation. Continue Reading →

Strengthen Your Commercial Roof with Heat Welded Seams in Lynnwood

Heat Welded SeamsIt’s not always the roofing panels or shingles that eventually wear out. Often, the roofing attachments begin showing signs of wear before the shingles. For residential and commercial roofs, one common treatment is heat welded seams. This method is known for its long-lasting durability and multitude of benefits.

The Advantages of Heat Welded Seams


Heat welded seams can resist strong environmental exposure to heat, cold, high gusts, stormy weather, and UV rays. When damage does occur to other types of attachments, however, welded seams provide a long-term and cost-effective solution. The process is just as viable for repairs as it is for new roof installations.

By contrast, when contractors apply low-quality adhesives, a form of roofing tape needs to be applied over the seams every seven to 10 years. Continue Reading →

Common HVAC Roofing Problems in Mukilteo

HVAC Roofing ProblemsMany facilities and warehouses have the HVAC system installed on the roof. Sure, this means a cool building interior that will keep the staff and customers happy. However, the very presence of the system can also be hazardous for the roof’s structural integrity. Find out what’s responsible for HVAC roof problems and how to prevent them.


Standing water can cause a leak and erode the roofing materials. Most HVAC systems utilize water that heats up and evaporates into the air. However, with a worn unit, the water may pool to the floor instead. The HVAC unit should have a discharge system that redirects water to the gutters.

Human Traffic

HVAC contractors are not roofers; they’re not trained to look out for the roof’s health. The crew can unknowingly damage the roof by haphazardly tossing tools around or stepping in areas not designed for foot traffic. Whenever you bring in an HVAC technician to perform maintenance, it’s a smart move to also bring in a commercial roofer and have the two work together. A roofer may, for instance, install walk pads around the HVAC system to prevent wear and tear from foot traffic while the unit is being serviced. Continue Reading →

The 3 Types of Residential Roof Skylights in Mercer

Roofing Skylight Types │ Mukilteo │ Urbizo Bros RoofingSkylights are a stylish addition to any residence. Not only do they increase visual appeal, but they also enhance energy efficiency. Other advantages include reducing lighting costs and providing natural light in low-lit areas. Residential roofers typically provide and install three roofing skylight variations, each with its own respective characteristics

Fixed Skylights

As you might infer from its name, a fixed skylight is just that: a skylight with a window in a fixed and non-adjustable position. These are great for any room needing more natural lighting. Homeowners also have selections between flat and dome-shaped windows.

Tubular Skylights

Tubular skylights work well in enclosed spaces, such as closets and foyers. The tubular shape of the glass is advantageous in the sense that it doesn’t contribute to either heat loss or gain. Depending on the type of glass or plastic used, the circular shape provides natural lighting equivalent to an incandescent bulb generating 300 to 1450 watts of power. Continue Reading →

Watch Out for Storm Chasers in Mill Creek

urbizo-8The Seattle area isn’t exactly known for strong thunderstorms. Nevertheless, they do occasionally occur. There was, in fact, quite a strong storm in early 2015 that included golf ball-sized hail. In the aftermath of a storm, homeowners need to be aware of unscrupulous storm chasers.

Who Are Storm Chasers?

No, we aren’t referring to the dare-devilish men and women who film storms dangerously up close. “Storm chasers,” in this context, are people who pose as residential roofers and offer to fix your roof at an extremely low fee. They may also provide other services, such as straightening your gutters or restoring damaged siding.

Storm chasers typically prey on a town right after it has been hit by a storm. They may even claim to operate locally and have a local address. What they actually do is purchase the name of a defunct roofing company. Continue Reading →

Seamless Gutters Vs Traditional Gutters in Mukilteo: The Difference Explained

Seamless & Traditional GuttersIf you’re having the roof renovated, then the gutters might also require replacement. You’ll have to choose between seamless gutters and traditional gutters. Now is the ideal time for installation. You want it installed in the summer or early fall so that it’s ready by autumn when the rain begins to pick up in the Mukilteo region.

Selecting Between Seamless Gutters and Traditional Gutters

Contrary to belief, seamless gutters are not comprised of one large single piece. There are seams at the corners and outlet tubes.

Traditional gutters – also known as sectional gutters – typically come in 10 to 20-feet sections with multiple seams. They also have separate end caps, corner pieces, and drop outlets for connecting to the downspouts.

Seamless gutters are often preferred over conventional ones. Does this make seamless gutters more beneficial over their sectional counterparts? Here’s the deal about traditional gutters: they’re just as durable as the seamless variety – if properly installed. Due to the multiple sections, it’s easy for an inexperienced contractor to incorrectly connect two seams. Continue Reading →

4 Benefits of Bitumen for Commercial Roofing in Edmonds

urbizo-roofing-6Bitumen is a common selection for commercial buildings and warehouses with a flat or shallow-angled roof. Bitumen is made from synthetic rubber that’s welded to a single roofing membrane. There are numerous advantages associated with bitumen roofing, and it’s a popular form of commercial roofing due to its durability.

Four Reasons Bitumen Roofing Are Beneficial


1. It Performs Well in Cold Climates

Bitumen performs exceptionally well in frigid weather. The material remains flexible even under sub-zero temperatures. This prevents the material from cracking or leaking. Granted, it doesn’t get super cold in the Edmonds area, but it’s a nice reassurance to have.

2. Slash Your Energy Bill

White roofing is becoming a major trend. This is any type of roofing fitted with a light-colored surface with heat-reflective properties. This means it won’t hold onto heat on a sunny day, thus keeping the interior cool. Bitumen typically comes in a light color for this very reason.

3. Fast Installation

Traditionally, bitumen required a labor-intensive, heat treatment method during application. Nowadays, there are cold-adhesive options that are practically self-adhering. Application is simple; you just unroll the bitumen over the roof membrane as you peel off the back. No, it’s not a DIY job, but the relative ease of installation translates to lower labor costs.

Why the Shingles’ Wind Rating Matters

urbizo-5If you live in or around Mukilteo, then you know the region is prone to high winds every now and then. This is why the shingle wind rating matters. Unfortunately, it’s also one of the most overlooked aspects by homeowners. A qualified residential roofer, though, can assist you with the right decision.

Shingle Wind Rating Explained

The ratings indicate the level of wind gust a shingle can withstand. A shingle’s rating is mostly determined by two factors: the material and number of fasteners used.

Shingle Material – Always look at what the shingles are constructed from. 3-tab shingles, for instance, have a wind rating of 60-90 mph. Similarly, laminate/composition shingles are a bit sturdier with a rating of 110-130 mph. Finally, presidential-style shingles, which we highly recommend, have a 130 mph rating. This is more than enough to withstand the occasional high winds of the Pacific Northwest.

Number of Fasteners – The number of nails used is also a deciding factor. Laminate/composition shingles with four to five fasteners will typically have a 110 mph rating. The rating is upgraded to 130 mph if six fasteners are used. By fasteners, we mean nails and not staples. Securing shingles with staples, in fact, will most certainly void the manufacturer’s wind rating warranty. Continue Reading →

Roof Shingles Vs. Shakes: How Do They Differ?

urbizo-4Many homeowners are familiar with residential roofing shingles, but very few have heard of roofing shakes. Some homes are fitted with shakes though the homeowner thinks they’re just shingles. Roof shingles vs shakes is a common industry topic that warrants more attention.

Roof Shingles vs Shakes Explained

Shingles are the typical tiles you see on the roof. They’re cut and more precisely milled than a shake. They have a more refined and classic appearance, making them suitable for post-Victorian style homes of the late 19th century. They’re also an appropriate fit for contemporary homes.

What, then, is a roofing shake? Traditional wooden shakes are made from lumber logs split on one end; this is the side that faces outward. One side is also thicker than the other. Shakes have a grainier and rustic appearance due to their jagged and uneven surface. This makes them a compatible fit for country- and cottage-style houses. Continue Reading →

Why Convert Your Old Cedar Shake Roof?

cedar shinglesConvert Your Cedar Shake Roof to Asphalt Shingles in Edmonds

Traditional cedar shake roofing is going out of style and for good reason. In decades past, cedar shake was the go-to roofing choice for most homeowners in the Pacific Northwest. However, traditional cedar shingles made from old-growth Western Cedar are becoming increasingly difficult to come by due to cutting restrictions aimed at preserving this resource. Now is the time to convert your cedar shake roof to asphalt shingle. Find out why this is the smart choice.

Cedar Shakes No Longer Eco-Friendly or Economical

Besides not being a sustainable resource, cedar shake can be expensive to maintain. Naturally combustible, most cedar roofs are treated with chemical preservatives to improve fire resistance. To preserve your wood shake roofing, regular treatments are needed to reduce rotting, warping, moisture absorption, and moss growth. The cost of these treatments can really add up over time.

Wood Shake Wears Faster

The life expectancy of a natural cedar roof is 15 to 20 years, but the material tends to lose its aesthetic appeal after only five to 10 years. What was once a beautiful contributor to your home curb appeal later becomes a major visual detraction. Continue Reading →
