What will a new roof cost?

The price of a new roof varies widely, depending on the material selected, the contractor doing the work, the home itself, area of the country, local labor rates, and more. Keep in mind that cost is only one factor, and it must be balanced against the quality of workmanship and materials. There are a variety of material options including composition, wood, metal, clay, concrete, slate, and PVC. These materials vary in quality, style, shape, and price. You need to look at the full product range and make a choice based on your budget and needs.

Within the roofing profession there are different levels of expertise and craftsmanship. Pick a contractor who is committed to quality work so you are sure they will be around to take care of the roof you put on.

I found a soft, spongy spot on the roof when I was walking on it, what does this mean?

By |October 29th, 2012|Uncategorized|Comments Off on I found a soft, spongy spot on the roof when I was walking on it, what does this mean?

If you can tell there’s a soft spot on your roof, this most likely means that the substrate below the roofing material is damaged and deteriorating. This can be a result of the plywood sheeting becoming wet from rain above or from moisture not being able to escape from below and leading to mold/mildew growth on the wood. If there is inadequate ventilation, the probability of moisture buildup and then mold/mildew growth is much higher. This can result in rotting substrates and cause your spongy soft spots on the roof.

When we roof a house, we use a plywood substrate rather than particle board — it’s stronger and more resilient to such occurrences, so keep this in mind when making decisions on your own roof.

This photograph shows the process of replacing the substrate and installing proper ventilation (added holes, or bird block vents, in the beams to let the air pass through). You can see the rotted particle board & insulation in the top left photos, Miguel drilling holes for ventilation, properly battened insulation (cardboard material to keep insulation from blocking airflow) and then your finished product in the bottom right.

I’ve noticed some of the shingles coming loose on the roof, is it time for a new roof?

By |July 2nd, 2012|Uncategorized|Comments Off on I’ve noticed some of the shingles coming loose on the roof, is it time for a new roof?

Shingle damage can definitely be an indicator of a roof reaching its final days, but it’s best to have a roof inspection done before jumping to any conclusions.  If you are noticing any torn shingles or if they end up in your yard after a storm, that’s a strong indicator that it’s time to get a professional opinion on the state of your roof.

Make Sure Your Attic is Baffled, & Not You.

By |June 11th, 2012|Uncategorized|Comments Off on Make Sure Your Attic is Baffled, & Not You.

Attic insulation baffles are forms, typically made of cardboard or plastic, that create a gap between the attic insulation and the roof sheathing, allowing air to flow from the soffit vents into the attic itself. Baffles are secured to the roof sheathing near the eaves. They effectively prevent the attic insulation from covering the soffit vents, promoting airflow from the soffit vents across the roof sheathing to the ridge vents. Without the baffles, you can have blocked airways and trap in unwanted air and moisture.

Proper attic ventilation is essential to the preservation of the roofing materials and roof sheathing. In the past, gable vents and static roof vents were the norm. In modern construction a combination of soffit vents and ridge vents are considered much more effective, and without being baffled, the insulation has a tendency to render your properly vented roof system useless.

The older gable vents (or cross ventilation) require outside influence to create airflow through the attic. Also, because the gable vents are typically installed about the mid-point of the attic, hot air is trapped at the apex of the attic. Static roof vents (or box vents) allow some hot air to escape, but like gable vents, allow hot air to be trapped under the roof ridge.

Ridge vents and soffit vents create airflow by utilizing thermal convection. The hot air rises and escapes through the ridge vents. This creates an area of negative air pressure, which pulls air into the attic from the soffit vents. The air is drawn directly across the roof sheathing, bringing it closer to the outside temperature. Problems with this system arise when the soffit vents are blocked, and the flow of air is impeded, usually by attic insulation. The problem is solved by installing insulation baffles, which are essentially a tube through the attic insulation, through which air can freely flow.

There are some areas of standing water on my roof, is this normal?

By |May 7th, 2012|Uncategorized|Comments Off on There are some areas of standing water on my roof, is this normal?

When water stays on your roof, as a general rule of thumb, that’s a bad thing. Any standing water leads to a higher probability of it finding a way to create a leak. When installing flat roofs, we typically construct a positive drainage system which keeps a constant and slight angle to insure that water finds its way off of your roof. Helping water to travel safely down and off your roof is of the utmost importance when considering your roof’s construction.

(click image for larger view)

Once a year inspections can discover cracked, warped, or missing shingles, loose seams and deteriorated flashings, excessive surface granules accumulating in the gutters or downspouts, and other visible signs of roof problems. Indoors you can look for cracked paint, discolored plasterboard, and peeling wallpaper as signs of a leaking roof system. By simply being aware of your roof and home in general you can prevent any of these problems turning from bad to worse. Inspect your home when you have the chance and at least once a year.

If moss is growing on my roof, is that a problem?

By |March 22nd, 2012|Uncategorized|Comments Off on If moss is growing on my roof, is that a problem?

In moist areas, such as the Pacific Northwest, moss can and will grow on shingles. Although the moss doesn’t necessarily ruin your shingles it can have negative effects. Moss can divert the path of water draining off of your roof, it can discolor the shingles, separate or lift your shingles, and it can retain moisture on your roof.

While moss isn’t the most serious issue, proper maintenance and preventative care can truly help the longevity and appearance of your roof. Moss can be brushed off, or if needed, can be sprayed off or treated with a moss-killing chemical.

Can I cover over my existing roof?

By |March 1st, 2012|Uncategorized|Comments Off on Can I cover over my existing roof?

Installing a roof over the top of an existing roof is possible, however, it’s not recommended. Some manufacturer’s warranties will not guarantee their product when it is installed over an unacceptable substrate. We believe that your roof is only as strong as its’ weakest link, and therefore prefer to accept responsibility for the craftsmanship of your home and start the re-roofing process from the actual structure.

How long should a roof last?

By |February 9th, 2012|Uncategorized|Comments Off on How long should a roof last?

Like any building component, roofs degrade at different rates depending on a large number of factors: The quality of original construction, the level of abuse, weather, the level of maintenance, appropriateness of design, material used, etc. So how long should a roof last? A poorly installed roof may show signs of failure on the first rain. There are also well-crafted roof systems that use durable materials and, if well-maintained, have lasted decade upon decade (for example, some of the natural slate roofs found in the Swiss Alps have lasted over 100 years *see picture). Most building owners, roofing contractors and designers feel 25-30 years is an acceptable service life.

Pilchuck Glass School’s New Wardrobe

By |November 28th, 2011|Uncategorized|Comments Off on Pilchuck Glass School’s New Wardrobe

In 1971 Dale Chihuly, Anne Gould Hauberg, and John H. Hauberg founded the Pilchuck Glass School in Stanwood, Washington. Pilchuck is a glass education center that has a reputation deserving of it’s international student-base and acclaim. 

The Hot House, a traditional barn-style structure, is Pilchuck’s signature building and needed to be reroofed with the care and style of its original craftsmanship. Jorve is extremely proud to have been the chosen partner in this magnificent reroof.

Pilchuck’s Hot House is truly unique and its’ barn-style shakes definitely contribute to its’ inimitable nature.

These shakes are custom hewn to 52” in length, as opposed to your houses’ standard 24”, and are installed over an open-frame timber building without a roof deck (picture to the right). An open-frame means that the shakes are the only layer of roofing material keeping rain from falling inside the building. With this in mind, to keep the Hot House waterproof, the shakes are double-coursed to stagger the space between each shake and usher the rain off the roof.

Jorve is proud of a job well-done and special recognition goes out to our crews on the job, veteran cedar shake specialists William Mejia, Eliseo Mejia, Adolfo Flores, Orlando Rodas, and Andres Hernandez. The job wouldn’t have been the same without custom copper and sheet metal fabrications by Mike Harvey and Antonio Munoz. This project was a chance for us to show our industry-leading abilities, attention to detail, and capacity to be flexible; we’re proud to say that this was achieved and the reroofed Hot House looks fantastic!
