When installing wood roofs, it is very important to ensure that the joints in adjacent rows do not align. Sidelap is the distance from one joint, to the joint in an adjacent row. The minimum sidelap is 1.5 inches. The joints in alternate rows should not align either. When the joints align there is a greater chance of leaks to occur. Most roofers understand this, and I have never seen a roofer install shakes with the joints aligned.
However, sometimes the shakes can split due to hail strikes or other causes. Sometimes, this can result in the joints of the shakes to be aligned. In the photo below you, the middle arrow is pointing to a split shake. Now, the joints in the three rows are aligned. As the water gets in at the top joint, it will have an easy path to the attic below. If you have a leak, this should be something your inspector should look for.

Testing for Radon in Richmond Apartments
It is not uncommon for tenants of apartment buildings to ask us whether or not their unit should be tested for Radon. The simple answer is yes. Radon is the second leading cause of lung cancer in the US. If you smoke, and you are exposed to high levels of Radon, your chances for getting lung cancer are significantly increased. Radon is a problem in Richmond, and high concentrations can be found in all buildings including apartment buildings. If you are concerned about your exposure to Radon, the first step is to ask your landlord if the building has been tested for Radon. If not, you can see if they are willing to have the whole building tested for radon.
If your landlord has not, and is unwilling to test your building for Radon, it would be prudent to get your own unit tested. High concentrations of radon have been detected in all floors of high rise apartment buildings. Radon tests are a cost effective way to determine your exposure. If you want us to perform a Radon test in your apartment, call us at 804-269-4321.

What is radon?
According the EPA ,Radon is a cancer-causing, radioactive gas. It is a gas that decays into radioactive particles that can get trapped in your lungs when you breathe. As they break down further, these particles release small bursts of energy. This can damage lung tissue and lead to lung cancer over the course of your lifetime.
How does radon enter your home?
Radon breaks down into a gas from Uranium which is found in almost all soils. The gas is able to travel through the soil and into your home through cracks in the foundation, expansion joints or gaps in the foundation, gaps or voids in the subfloor, contaminated water, and even granite counter tops. The radon gets trapped in the house and many factors can determine its concentration levels.

What is the risk in living with radon?
Radon causes 20,000 lung cancer deaths a year. It is the second leading cause of lung cancer in the United States. It is second only to smoking. If you smoke, or are exposed to second hand smoke, and you are exposed to radon, your chances to get lung cancer are significantly increased. The EPA as provided these charts to represent the risks associated with radon exposure.

What word are these home inspectors actually reaching for? Efflorescence! To keep it simple, efflorescence is the white powdery substance found on porous building materials such as masonry walls. As moisture moves through the wall, it brings salts with it, and as the water evaporates, it leaves behind the white substance. When a home inspector observes a significant amount of efflorescence, its an indication of a moisture problem. Since moisture is home enemy number one, the source of the moisture needs to be identified and measures taken to remove the source. The efflorescence itself is harmless, but where we find a lot of efflorescence, we also find mold, termites or other moisture damage.
The moisture can come from not having gutters,having gutter downspouts terminate too close to the home, running sprinklers too long, or even up from the ground. Most home inspectors can generate an accurate hypothesis on the origins of the moisture, but it is beyond the scope of an inspection to definitively determine the origins, or prescribe a repair. The point is, a home inspector should be able to properly identify, explain, and assign the
