Don’t Let Your Gutters Clog – Get a Gutter Guard for Your Sammamish Home

gutter guard sammamishGutters provide protection to your roof and foundation; they prevent water runoff from collecting and causing damage. The gutter system also needs protection from debris buildup. A gutter guard is a simple, inexpensive gem that your local roofing service can put up which will prevent the buildup of debris.

Types of Gutter Guards

Mesh guards have small holes that let the water in but keep most solid objects out.  Bottle brush guards are similar to pokey spikes you place on a rooftop to prevent pigeons from roosting. Their bristle-like material catches objects like leaves while allowing water to flow into the downspout. Nylon guards have a foam-like property that allows water to flow through but keeps nearly everything else out. Nylon is great for preventing ice and snow buildup. The reverse curve guard is a barrier placed over gutters. It has a downward curve which allows water to drip into the gutter and solid objects to fall to the ground.

Gutter Guards Don’t Mean Your Gutter Is Maintenance-Free

Although gutter guards are designed to keep most objects out, your gutter has to be inspected periodically. Pine needles, of which the Pacific Northwest has many, are small enough to get through most guards. Other tiny objects can also make their way inside the gutter.

Interested in Having a Gutter Guard Installed on Your Sammamish Home?

We’re happy to perform periodic inspections, clean your gutter and your gutter guard. We provide a comprehensive service that also includes deck and fence repair and installation. We can tell you from experience that, while a gutter guard is very useful, it’s not a substitute for maintenance. Contact us today for a free consultation!

Prevent Oil Canning in Your Kenmore Home’s Metal Roofing

oil canning kenmoreHave you noticed how some metal roof panels appear to bulge or have waves in them? This is known as oil canning, and it creates a look that’s unprofessional. All metal panels, including zinc, aluminum and copper panels, are vulnerable to this.

What Causes Oil Canning?

These bulges and waves can be caused during the manufacturing process. While being flattened, rollers with gaps in them distribute pressure unevenly, producing panels which aren’t perfectly formed.

Oil canning may also be caused by other factors, such as thermal expansion, improper storage, incorrect installation, or shifting of the beams and other support structures.

Can it Be Prevented?

Prevention is up to the manufacturer and installer. There is really nothing the homeowner can do. This is why it’s important to hire a reputable roofing contractor that, in turn, hires reputable sub-contractors. It’s also important to verify that the contractor has purchased his material from reputable manufacturers.

The best answer is to replace the panel which has been oil canned, although it can sometimes be repaired. Adjusting the internal supports to place additional tension on the outward side of the panel may solve the problem. A contractor can examine the roof and make a determination regarding repairs or replacement. More often, the latter is in order.

Prevent Oil Canning by Hiring Allied Construction

Give Allied Construction a call if you need a roof replacement. We obtain all of our materials, including roofing sheets, shingles, deck panels, and fence posts from longstanding and trusted distributors. We also do installations the right way. This prevents oil canning from ever becoming an issue in the first place. Contact us today for more information.

Winter Roofing Problems to Watch Out For in Bellevue

winter roofing problems bellevueThe Seattle area isn’t the coldest region in the U.S., but wind, rain, snow and sleet are all regular aspects of our weather. We’ll identify common winter roofing problems in Bellevue and their causes.

Two Major Causes of Winter Roofing Problems: Wind and Trees

When powerful winds tear at your roof, older shingles can rip away. Loose asphalt shingles can partially or completely peel away. These same winds can push branches onto your roof, damaging the upper protective layer. Older roofs are more susceptible to wind damage, but new roofs are also at risk because they havn’t fully settled. There’s no way of knowing whether your roof will be affected by wind damage, which is why it’s best to inspect your roof after high winds and storms.

Condensation and Flashing Leaks

Condensation forms when air comes in contact with a cold icy surface. If the attic below your roof isn’t sufficiently insulated, the area can become a breeding ground for mold. Adequate roofing ventilation is also important, especially during winter.

Sloped roofs are prone to leaks around the flashing. Winds can loosen the flashing and cause water entry. Contrary to popular belief, flashing repair requires more than just caulking the area with sealant.

We’ll Inspect Your Roof in Bellevue

Has your neighbood recently endured strong winds or heavy rain? If you only inspect the roof once a year, this is the time of year to do it. Contact Allied Construction for a roof checkup. You may also want to consider a deck or fence if renovating for the start of 2021. Correcting winter roofing problems, though, should take precedence. Contact us today for all your construction needs.

Fortify Your Home in Kirkland with Stone-Coated Metal Roofing

Stone-Coated-metal-Roofing KirklandKirklandingRoofing styles evolve over the years. Stone-coated metal roofing is one style that is garnering a lot of hype in the home improvement industry. We’ll discuss this increasingly popular roofing trend and why it’s a favorite among home and business owners in Kirkland.

What Is Stone-Coated Metal Roofing?

Stone-coated metal is constructed from reinforced steel and highly resistant to physical impact and weather-induced corrosion. As suggested in its name, the surface is coated with stone chips and sealed with an acrylic resin film. Stone-coated metal can also come in the form of tiles and shingles. This makes them suitable for various architectural styles, from contemporary to the cottage look.

Why Should You Consider Stone-Coated Metal Roofing?

Durability: This roofing type has a life cycle of 50 years, with most warranties lasting 30 years or more.

Energy efficiency: Metal roofing is traditionally known for its insulation properties. With this investment, you can slash your energy bill by as much as 50%.

Weather Resistant: Coated metal doesn’t corrode from exposure to heavy rain or peel away during heavy gusts. Snohomish County isn’t even exactly tornado alley, so this is mostly a nonissue.

Insect-Proof: The metal is safe from boring insects, not to mention mold and mildew growth.

Fire-resistant: this metal roofing has a class-A fire rating. This ensures conformity with local building codes.

Style: Is metal too industrial-looking for your liking? Stone-coated metal can take on the appearance of … you guessed it, stone. It can also simulate the look of wood to match the look of your deck or picket fence. Other styles include old-world Roman tiles, weathered wood, traditional Spanish barrel tile, and granite.

Invest in Your Roof Today

Upgrading your roof is one of the best home investments. Allied Construction provides various roofing styles, but we wanted to give special attention to stone-coated metal roofing because of its rising popularity. Contact us today for more information.

What to Know About Roof Membrane Shrinkage in Kenmore

roof membrane shrinkageYour roof is comprised of more than shingles, tiles, or metal sheets. Most homeowners are unaware of the sheet, or membrane which lies beneath the roof. Roof membrane shrinkage is a common problem and can affect your home’s insulation and lead to problems like leaks and mold.

What Causes the Shrinkage?

Oil additives are often used during the roof membrane installation. Exposure to heat and cold can cause the oil to evaporate or harden. This causes the membrane to lose its flexibility and it begins to shrink. For larger homes and businesses, a membrane shrinkage of even 1% or 2% can result in a reduction size of up to several feet.

Damage to the Roof’s Surface

As the membrane shrinks, it can begin to pull away from the flashing, thus creating openings for leaks. Membrane shrinkage can also cause visible damage to the roof surface. This includes cracks, crazing, splitting, and ridging of shingles. In some instances, shrinkage can also damage wall masonry. As the membrane shrinks, it may yank and pull at the wood blocking and gravel stop it’s attached to. The wood block is often attached to the masonry, thus causing some of the brick or stonework to get ripped away as the wood block is pulled by the shrinking membrane.

We’ll Inspect your Roof Membrane in Kenmore

Let Allied Construction inspect your roof. For re-roofing projects, we can also redo the membrane altogether. This includes using more durable material like PVC. You can schedule a roof inspection as part of a bigger renovation that also includes other areas of the home like the deck and fence. Contact us today for expert roofing.

Avoid Damage Caused by Poor Roof Ventilation

poor roof ventilation WoodinvilleAn improperly ventilated roof can cause homeowners a lot of trouble. Aside from premature wear and damage, poor roof ventilation can cause more heat to seep into the home during summer months. This, in turn, forces your AC system to work harder, leading to higher energy costs. Having a roofing service ventilate your roof will keep it in tip-top shape and it will last longer.

The Consequences of Poor Roof Ventilation

Simply put, poor ventilation accelerates your roof’s need for replacement. It leaves shingles and slates vulnerable to mold and mildew. Snohomish and surrounding cities have high humidity, which puts homes and facilities with improperly ventilated roofs at risk. Trapped moisture can also cause the slates to crack.

Prevent the Formation of Ice Dams

Too much moisture and air also leads to the formation of ice dams in the winter months. Ice dams create melted water that drips into the insulation and exterior walls, where it can ruin the paint and sheet rock. The ice can also pull apart shingles and gutters. Worst-case scenario, the weight of the ice can cause a roof collapse.

Improving the Ventilation

Ventilation comes in several forms. This includes static, ridge, gable, and soffit vents just to list a few. Most roofers recommend one foot of exhaust and intake ventilation for every 300 square feet of roof. Ultimately, your roofer will make a personal recommendation based on the current condition of your home. For an inspection, additional roofing tips, or other home renovation services like deck rebuilding, contact Allied Construction. Roof vents are just as vital as the shingles, slates, and beams, and we’ll fit your home with the proper ventilation system to ensure proper air flow.

4 Steps for Roof Moss Removal in Woodinville

Roofing Tips| Roof Moss RemovalAnyone who lives in Western Washington knows all about moss growth. That’s because the moist, cool climate offers perfect growing conditions. Also, wood shake and composition roofs provide the most ideal places for moss to take hold. Roof moss removal is no fun, but if you allow growth to go untreated, you will need a full roof replacement sooner than necessary.

For safe and effective moss treatment, hire a roofing contractor. Want to try roof moss removal on your own? Here are 4 tips for roof moss removal:

1. Treat Your Roof

Herbicides like Moss-Out can kill existing moss. Depending on how much moss there is, you may need more than one treatment. Also, spring and fall are the best times to do this service.

2. Clean off Debris from the Roof Moss Removal

After killing the moss, a thorough and careful power washing by a roofing cleaning professional will remove all debris.

3. Repair Roof Moss Damage

Roof repairs may be necessary if the moss has been there long. Therefore, to keep leaks from developing, have your roofing contractor look for problem areas. After the inspection, they will recommend repairing or replacing damaged shingles or shakes. The sooner you remove the moss, the less extensive (and expensive) repairs will be.

4. Prevent New Growth

Even with treatment, there’s always the chance moss will come back. However, there are some steps you can take to reduce this risk. A few best practices are regular roof cleaning, installing of zinc strips, and removing overhanging tree branches.

For a permanent solution, especially if your roof needs to be replaced anyway, consider a new metal roof. Metal is resistant to moss growth. Also, metal has the added benefit of curb appeal and energy efficiency. Therefore, a metal roof improves the value of your home and helps you save on energy bills.

Material Options for a Mobile Home Roof

mobile home roof material, mobile home roofMobile homes make up a sizable portion of residences in the greater Snohomish area. Like a traditional home, mobile living units require a durable roof. What are your options for mobile home roof materials? Are the selections more limited than those for traditional homes?

Asphalt Shingles

Asphalt shingles are a mainstay in conventional homes with a sloped roof. They are also available for mobile homes. There is one major difference, though. Installing a second or even a third layer over existing shingles is common practice during renovations and repairs on conventional housing. However, only a single layer is allowed in a mobile home. If the roof requires replacement, all of the existing shingles need to be removed.

Slate Shingles

Slate shingles are beloved for their beautiful natural stone look. By no means do they look out of place for a mobile home. They are also incredibly durable, lasting 80 to 100 years and also hold up well against humidity and wind. Slate is quite heavy, though, so you’ll need to verify that your mobile home can support the weight of this material.

Metal Roofing

Metal is highly durable and requires little maintenance. However, depending on the construction of the mobile home, metal roofing may not be a good fit. If the architecture is composed mainly of 2×2-foot lumber, for example, then metal panels might not work.

Composite Roofs

Composite roof shingles resemble traditional asphalt or slate shingles but are made from composite material like rubber and polymer. They are typically lighter weight and also more affordable. The light weight, though, gives them a lower wind resistance rating. However, if installers adhere to strict installation protocol, this shouldn’t be a major concern.

We Install Various Roofing Materials on Mobile Homes

We service roofs for mobile homes on a regular basis. More homeowners are also enhancing their mobile property with fencing and/or a deck. Contact Allied Construction if you own a mobile home or are having one built. Your mobile home roof material options are quite diverse.

Winterizing Your Roof: Prep it for the Upcoming Cold Spell

winterizing roofThe Pacific Northwest isn’t the coldest region by a long shot, though it can get quite frosty. Your roof will feel the effects as much as you do. This is why we suggest winterizing your roof. Here are some tips to help you offset the impact.

Visual Inspection

A visual inspection from ground level is insufficient. You actually need to be on the roof to spot any signs of damage. Due to the inherent risks of climbing a ladder to reach the roof, we suggest leaving the pre-winterizing inspection to a professional roofer. However, you may certainly do this on your own if you are comfortable with these types of DIY tasks.

Signs of damage to look for include loose or torn shingles and rot. While seemingly minor, the arrival of snowfall can exacerbate the existing damage. Continue Reading →

Three Metal Roofing Misconceptions Debunked

metal roofing

Shingles aren’t your only roofing option. Metal roofing is growing in popularity among residences due to its durability. There are a lot of half-truths about this type of roofing that are simply not grounded in reality. Let’s consider some of the most prevalent metal roofing misconceptions

Misconception #1: Metal Roofing Isn’t Right for Contemporary Homes

When it comes to metal roofs, one often thinks of corrugated tin roofing panels associated with weathered-down barns and sheds. In reality, though, metal roofing nowadays comes in various styles and complements modern residences quite nicely. It also fits in with many architectural design schemes, such as stone and vinyl siding.

Misconception #2: Metal Roofing Absorbs Heat

Metal absorbs heat; that’s common knowledge. Therefore, homeowners believe metal roofs absorb heat, which would make hot summers seem even hotter. This is actually not true with respect to modern metal roofing. Thanks to new innovations, metal panels now have high reflectivity and emissivity. This makes them less of a heat absorber than most types of shingles.

Misconception #3: My House Can’t Support a Metal Roof

It’s true that weight considerations are a significant factor during a roof installation. This is especially the case with respect to residential roofing. However, contrary to popular belief, most metal roofing panels are actually lighter per square-foot than most shingles.

The weight isn’t a major cause for concern whether you select metal or shingles. Some installers, however, install new shingles over existing ones without removing the old ones. This doubles the weight of the roof; this is when the roof’s weight becomes a pressing concern.

Don’t Fall for Metal Roofing Misconceptions

We install/replace residential metal roofing. Give Allied Construction a call for roofing work or for services for your fence or deck. By dispelling these metal roofing misconceptions, we hope more homeowners will begin to consider this option for their next roofing upgrade.
