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.

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 →

Roof Inspection Or Survey: Know the Difference

roof inspection or surveySometimes people don’t know whether to ask for a roof inspection or survey because they use the terms interchangeably. Do they have the same meaning? At their core, no. We’ll explain how an inspection differs from a survey and how they apply to both residential and commercial roofing.

Roof Inspection Vs. Roof Survey

Clients often use the term roof inspection when they need a professional to examine the roof for damage or routine maintenance. When customers say they need an inspection, what they actually need is a roof survey.

Roof Survey

A roof survey is a pre-project examination where a contractor looks over the roof and takes notes of the required repairs. Four out of five times, this is what a client actually needs. Continue Reading →

What Should You Look for in a Reroof Proposal?

reroof proposalA reroof proposal is just a fancy term for a contract. When you hire a professional, the contractor will draft a reroof proposal outlining the provisions of the agreed service. We advise homeowners to review the contract carefully because it reveals a lot about the quality of the contractor.

Basic Contract Provisions

Some contractors use a standardized form and simply fill in a few blanks that vaguely describe the terms of service. Some even just supply a hand-written note that includes nothing more than a list of required material and the total cost. This is a red flag for possible spotty workmanship.

A legitimate contractor will draft a very detailed proposal for all residential and commercial roof work. A contractor also only drafts a proposal after an inspection of the roof. Be wary of roofing companies that draft a contract without performing a thorough inspection. Continue Reading →

Algae Vs. Mold Growth on Your Roof

Algae and Mold GrowthDo you spot black streaks across your roof? Are those streaks a sign of algae or mold growth? Are the two equally as bad? We’ll explain the difference, how to distinguish the two, and how to treat them.

Algae and Mold: The Difference

Algae is simply a moss-like plant form that thrives under moisture and sunshine. It spreads through airborne spores and is common among residential roofs made from asphalt shingles. Algae is also much more common than mold, and that’s a very good thing. While algae on a roof can be an eyesore, it’s not dangerous, nor does it cause damage.

Mold, on the other hand, is a much greater cause for concern. Black mold is especially dangerous as it releases toxins that can cause respiratory issues, ranging from headaches to severe coughing fits.

How to Tell the Difference between Roof Mold and Algae

Both algae and mold manifest as black streaks, so a visual inspection from ground level is not enough. Mold thrives under damp and poorly ventilated conditions. Inspect your attic and crawl spaces for signs of mold. If everything appears okay and black streaks manifest solely on the roof, then it’s likely the more harmless algae.

Treatment of Roof Algae and Mold Growth

Treatment options for both mold and algae are more or less the same. Prevention is the best step; we recommend regular pressure washing for the roof. This is best done by a professional; using too much pressure can damage the roof, and not using enough gives the roof nothing more than a light wash.

We Treat Algae and Mold Growth

Both residential and commercial roofs are susceptible to algae and mold growth. Urbizo Bros Roofing can restore roof surfaces. We also provide other home services, such as gutter installation, which prevents water from collecting and creating the damp environment conducive for algae and mold growth.

Do You Need Walk Pads for Your Commercial Roof?

walk padsWe recommend walk pads for commercial roofs with HVAC systems and other roof-installed units. Don’t have walk pads? Consider installing them before the next HVAC/utility inspection. The pads will prolong the life of your roof by preventing damage.

What Are Walk Pads?

Walk pads come in rolls and are made of the same materials as the roof. We install them as part of our additional roof service. The pads provide a stepping surface for maintenance workers and a place to set their tools. Without them, workers may cause punctures or other damage to the roof membrane with their hard-soled shoes or sharp-edged tools.

Roof inspectors know to use walk pads to protect the roof during their own maintenance work. However, other types of workers, such as HVAC technicians, solar panel installers, and cable satellite crews must be educated. They’ll treat the roof as a sidewalk and haphazardly leave their tools everywhere. Continue Reading →

3-Tab Vs Laminate Shingles: What’s the Difference?

3-tap vs. laminate shinglesPeople tend to think that all shingles look the same and are composed of the same material. Shingles are, in fact, diverse in appearance and composition. In fact, we offer two primary styles of shingles when renovating residential roofs. Which to choose? 3-tab vs. laminate shingles.

3-Tab vs. Laminate Shingles: Two Sturdy Roofing Options

3-tab and laminate describe two different styles of shingles. The difference is mainly an aesthetic one, though durability factors in as well.


3-tab shingles essentially have a uniform appearance. Every shingle is the same size, shape, and dimension.


Laminate shingles are also referred to as architectural or laminated architectural shingles. These are more or less your standard asphalt shingles. Some of the shingles, however, have an additional material layer or a heavier base mat. In addition, the shingles may also differ in size and shape. The result is a multi-dimensional look where some of the shingles extend over the others. Continue Reading →
