Unfortunately, when you buy a home you don’t receive an owner’s manual along with it.  You’re home is probably one of the most expensive purchases you will make. The work that you are considering should not be taken lightly.  The decisions that you make here, can cost you or save you a great deal of money.

This “After” photograph was cleaned for a Mortgage company and received a certification.
This “Before” photograph was cleaned for a Mortgage company requiring a certification.  When we “Quick Serviced” this roof we were told that the roof was 3 years old and that it had no debris on it.  It was 17-year-old second layer roof without any maintenance since it’s inception. This “After” photograph was cleaned for a Mortgage company and received a certification.

Protecting and Maintaining the roof that protects you, you’re family and you’re possessions should be a primary concern.

Here is some general information for you regarding your roof, from Jet Clean ™.

A composition roof expands as it heats up during the day and contracts at night when it’s cooler. Your roof also swells when it rains and shrinks when it’s dry. So, on a daily or seasonal basis your roof does absorb a lot of natural abuse – expanding and contracting, expansions and contractions. If your roof is never allowed to dry out, it will just rot. 

Repairs completed correctly make all of the difference for your roof
Repairs completed correctly make all of the difference for your roof.  This roofer repaired this roof “Horribly” and then left the remaining unused composition on the roof.  We estimated that these repairs were done approximately eight years prior to the taking this photograph.  This is a great example to let you know that you won’t know the quality of work that your roofer has done, for several years down the road. Hire the company that you trust.

Jet Clean Roof Restoration Contractor Seattle Washington For example:

In this situation… If your house is near trees, the debris from those trees will settle on your roof acting as a sponge collecting all of that moisture as it sits. These debris will not allow your roof to dry out and in turn, will dramatically shorten the life or your roof. 

Jet Clean Roof Restoration Contractor Seattle Washington Pollution, floating pollens, airborne spores and residual debris are a great food source for moss. All have the destructive capacity of absorbing and holding water. Shaded areas such as overhanging branches, roofing and walls are all perfect breading grounds for moss to grow. The Northern facing surfaces of roofing generally get the least amount of the sun and in turn will take longer for moisture or dew to evaporate or run off. The steeper the roof pitch, the more moss will grow. Moss creates an additional problem with its root system by compounding the deterioration process further causing the composition to pit and crack. Eventually, your roof will just leak and most likely cause damage inside of your home until its repaired or replaced.

Jet Clean Roof Restoration Contractor Seattle Washington Wind is really not a problem in the Pacific Northwest, unless the roof is constructed improperly. Most manufacturers have limits of liability on there products if the wind speed is above 40 +/- knots, before the warranties are effected or expire. If the composition tar strips haven’t sealed properly, the winds could cause rain to be driven and penetrate your roof by blowing water under the roofs each individual tabs or shingles. A heavy wind could also blow the rain directly under your valleys, flashing, ridge vents, skylights and siding. The initial construction of your roof or the quality of the roofing product itself, is generally the largest considerations here.

Jet Clean Roof Restoration Contractor Seattle Washington Sun on the other hand is a serious threat to your roof. The sun and its powerful UV radiation can bake the life right out of your roof. Consider that on a hot summer’s day the roofs temperature can reach as high as 180 degrees Fahrenheit. The sun will cause the valuable unsecured granules to dislodge. These granules are the composition roofing protection against the sun itself. In example: Lighter colored composition granules will keep the home cooler by helping reflect the light along with the heat in the summer sun, and a lighter roof will also be cooler in the winter. Conversely, a dark colored composition granule roof will be warmer under the summer sun and will also be warmer in the winter. So if you have an opportunity to pick the color of your next roof… Consider that the color of the composition roofing that you choose, may save you money in you’re Energy Bills. Air conditioning in the summer or heat in the winter, depending on where you live may help you choose your next roof color. So, with damage done to your composition granules, please keep in mind… Once the granules are gone – there gone for good and so is the protection that they provide. The composition’s premature aging process begins from cupping… to brittleness… to cracks… to leaking… to repairs… to replacement…

Jet Clean Roof Restoration Contractor Seattle Washington HELPFUL HINTS

  • Keeping your roof “free of debris” weather it’s a total cleaning or just a periodic loose debris “Tune-up” will make all of the difference and your roof will last much, much longer.
  • Making sure that all of the leaks and seriously cupped and damaged tabs or shingles are replaced on a “as needed” basis will also make your roof last much, much longer.
  • Keeping people off of your roof. Knowing how to walk on composition roofing especially when the roof is hot and soft in the summer.
  • Zinc Strips are a good product for fighting moss growth or re-growth, and its natural. If installed properly to your roof, the rain will wash the metallic zinc compounds down the roof and won’t let the moss to grow. Zinc Strips are 3 inches wide (2 inches exposed to the weather) and as long in length as needed. The nails used to attach the Zinc Strips should not be exposed to the weather. If you look at your roof and notice existing galvanized vents and flashings… You might notice that under those galvanized (17% Zinc) products there is no moss growing for several feet.  The rain dilutes the Zinc Strips the further down the roof it gets.  Unfortunately, Zinc Strips are unsightly to a composition roof and Jet Clean™ discourages this product unless installed properly at the original construction of the roof.
  • Treating your composition roof for moss is “NOT” a good idea. It won’t work and it might cause damage to the composition surface itself.  A “water base” product will not absorb into your roof and will wash away in time, with the rain. An “oil base” product will dissolve the composition surface.  It’s our opinion, that you would be wasting your money having a composition roof treated.
