The town in New Mexico where I went to high school had a small mountain just outside the city limits. We called it Saddle Back Mountain.
We called it that because from a distance it looked like a saddle. The natural mountain shape was that which had a sway in the middle. That made it appear that a person could straddle the mountain and sit comfortably in its natural seat. The mountain actually looked like it was sagging in the middle. Sure had a lot of fun looking for arrow heads after school and on weekends. I still see things today that sag in the middle and they remind of that old mountain.
You see a lot of sagging pants that need to be pulled up. I’ve seen horses with sway backs, they sag in the middle too. And as we age it seems that about everything starts to sag. With all that being said we begin our discourse into what we really want to talk about … “sagging roofs.” Not good.
A sagging roof can be caused by several different issues. Improper design in the construction of the roof assembly triangle can be a major problem. The roof joists, rafters and ridgeline make up the roof assembly triangle. The triangle should be constructed with high quality materials for structural integrity. Sagging takes place when one or more parts of the triangle fails to support their weight design. At this point, you’ll need more than basic roof repair work, you’ll need a professional to help you get your roofing problem corrected.
Roof Weight Problems
Too much weight from an accumulation of snow can cause sagging. Water damage over a period of time can break down the strength of the roof design and cause it to sag, Often the joints of the triangle pulls apart this can cause sagging as well. Rotten decking can also cause sagging in the roof structure. Also using sheathing that is too thin can allow sagging.
Remember a sagging roof is “not normal” and it “can be dangerous.” When a roof begins to sag it is trying to tell you something is not right. You should immediately investigate to find the problem. It is possible for a roof to collapse. Begin by checking for faulty structural material, water damage, ventilation issues, even insect damage caused by wood ants and termites.
To ensure that a sagging roof problem is solved calling in the professionals is wise. Perhaps the problem is not serious enough to call in a structural engineer. But as a general rule of thumb it is a good idea to call your home builder or another building contractor for their expertise. Even a quality experienced remodeler can help you solve your sagging issues. They will take everything into account to make sure your sagging roof woes are eliminated.
Be aware that there are very few inexpensive remedies for most sagging roof problems. So do your research and find the best professional for your dollar. They are out there you just have to do your homework to find them.
What Do I Need To Know About Roof Pitch?
What is roof pitch anyway?
Roof pitch simply put is the steepness of a roof. It tells you the measurement of the slant or angle of your roof. Roof pitch is measured in inches, it tells you how many inches the roof rises for every 12 inches of depth. In order to have a 6:12 pitch the roof would rise 6 inches for every 12 inches in depth. The same would be true on a 9:12 pitch and a 10:12 pitch and so on.
The main reason the pitch of the roof is important is to ensure that the angle of the roof is adequate for rain and snow run-off. There are four basic categories of roof pitches: flat, low-slope, medium-slope, and steep-slope. But they are generally broken down into only two types: The low pitch and the high pitch.
Most low pitched roofs can be easily walked on making roofing installation easier, safer and often faster to install the finished roofing system. Because of the low pitch of the roof and because of the type of roofing material that can be used, it cost less to install the roofing system. Commonly low pitched roofs are easier to maintain and repair. An experienced roofing company like Barrelle Roofing, who is now roofing charleston, specializes in both low and steep pitch re-roofing.
Low pitched roofs are in general easier to heat and cool which translates into energy savings. The down side to low pitched roofs is it makes them more vulnerable to water leaks. The lower the pitch of the roof the more apt they are to water pooling or puddling which can lead to deterioration and water leaks.
High pitched roofs on the other hand requires less maintenance and can actually save you money in the long run. The high pitch of a roof allows rain and melting snow to drain quicker and easier than a low pitched roof. And because of the high pitch of the roof pooling or puddling cannot occur saving you money in repairs. High pitched roofs work well in areas of the country where there is heavy rains and snowfall. The steep pitch of the roof prevents the threat of heavy snow build-up which could cause the roof to collapse.
High Pitch Roofs
There are some disadvantages to high pitched roofs as well. The cost of installing a steep pitched roof is obviously more expensive than a low pitched roof. Installers have a steep-roof charge for high pitched roofs. More often than not installers have to wear harnesses attached to the peak of the roof in order to install the roofing system making it a much slower process than a low pitched roof. And because of its high pitch it involves more material which also translates into more cost. Sorry Do-It-Yourselfers, for quality and safety sake, all high pitched roofing systems call for professional roofers in order to get a quality finished product.
Let’s not overlook the pitch of a roof when it comes to aesthetics. Many builders are now using roof pitch as eye-appeal for selling their homes.
There’s no question… a high pitched roof has great curb appeal and looks expensive.
