Now when the talk is about commercial roofing contractor Andover MA, Quinn’s Roofing and Construction deserves a very special mention.
Just like with your residential property, the roof of your commercial building is the first line of defense. A high quality and durable roof goes a long way in protecting your business along with your employees, equipment, inventories and clients from serious natural hazards such as rain, sunlight, wind, hail, ice and snow. As the roof of your commercial establishment is continuously exposed to extreme weather conditions and other hazardous elements, it is not surprising that it is the most vulnerable part of the building. In fact, weather and other unessential elements more often than not lead to decay and deterioration, enhancing the risk of damage to the roof as well as the contents below it.
Whether you are constructing a new commercial building or renovating the existing one, roofing is an area which shouldn’t be overlooked whatsoever. However, there are a number of things that should be taken into consideration so as to prevent unfortunate accidents and costly repairs. Quality is a major concern because if the roof of your building will be more susceptible to the effects of water and moisture, then it will not serve the actual functionality. A leaking roof can result in damage to the roof’s rafters, structural support and also in other areas of your building, which may include mould growth and other complications. It is to be noted that you should only hire a certified and experienced commercial roofing contractor Chelmsford MA who can help you in the best possible ways by providing outstanding yet cost effective roofing solutions.

We know the effect seismic activity has on a building and how to minimize the impact of a quake. Earthquakes can cause a building to slide, shift off of its foundation and overturn. They can also buckle cripple walls, causing them to collapse.
Over the years we have learned the effect seismic activity has on a building and how to minimize the impact of a quake.
Earthquakes can cause a building to slide, shift off of its foundation and overturn. They can also buckle cripple walls, causing them to collapse.
House bolting is also called foundation bolting, anchor bolting, or seismic retrofitting. The purpose of house bolting is to make the structure safer and prevent damage during an earthquake. The bolts strengthen the wood frame by connecting it securely to the foundation. The two types of bolts commonly used in house bolting are epoxy foundation bolts and expansion foundation bolts.
If you live in an older home, an epoxy-set foundation bolt will be your best option. Older homes tend to have weaker concrete. Epoxy bolts are longer than expansion foundation bolts, which means they must be inserted deeper into the concrete. The deeper insertion improves the bolt’s performance.
Epoxy bolts are also a good choice in locations where the motion of a quake can lift up the structure. Because of the length of the bold, the chances of the wood frame pulling away from the concrete foundation is reduced.
Expansion foundation bolts are best used with foundation concrete that is in good shape, such as concrete in a new home or a new foundation in an older home. This is because the bolt requires “strong concrete” to be effective. The bolts can be used as long as they don’t crack the concrete.
Anchor bolts need to be installed with square plate washers. The washers create a sturdier and more secure connection to the foundation. Before square plate washers came into use, the bolts were secured with round washers. However, round washers did not have enough holding strength.
Sometimes other types of anchors may be necessary, depending on whether or not the home has cripple walls. Homes can also have a combination of cripple walls and places where the floor rests on the foundation.
To find out if your house needs bolting, go down into your home’s crawl space. The crawl space is the area between the foundation and the first floor. Find the sill plate, which is the board located on top of the foundation. Most but not all sill plates are made of lumber. The board runs horizontal to the vertical wall.
Inspect the sill plate for the head of anchor bolts. In most cases they will appear every four to six feet.
Many homes built during and after the late 1930’s will have some form of house bolting (Los Angeles and other earthquake-prone cities especially). Check to see if any existing bolts have become weak, or are set to far apart to provide the support needed in a quake.
Any work that gets done to strengthen the structure of your home needs to meet current standards. A foundation repair expert or foundation contractor should be consulted to determine if any existing bolting needs to be replaced, and the extent of any new bolting that may be necessary.
