building a home addition - what you should know

When building an addition to an existing home, many things can go wrong. If you don't know what you are doing, the addition may not be structurally sound, it may leak water and the electrical system could put the entire home at risk of a fire. When I added two bedrooms to the back of my house, I thought that it was going to be an easy project that could be completed in no time. Little did I know that there is a lot of planning that goes into this type of project. This blog will show you what you need to know before you begin building an addition.


5 Factors That Affect Commercial Roof Material Choice

Whether you are choosing materials for a new building or assessing the material options for a roof replacement on an existing building, making the right choice is important. There is a multitude of modern flat roofing materials on the market, so it could be time to upgrade. Keep these factors in mind when making a decision between the different roofing options.

1. Local Climate

Climate impacts everything from the best type of membrane to use to whether your roof needs more of a slope. Heavy rain and snow may mean that drains need to be added to the design. Some materials are also less prone to leaks in very wet climates, while others are more prone to temperature concerns. For example, in hot climates, reflective membrane roofs can reflect heat and damage from intense UV rays, while in colder climates bitumen roofs can help absorb warmth. 

2. Energy Efficiency

Many of the same qualities that make different roof materials suitable for their climate will also improve energy efficiency, such as heat reflective surfaces. Insulation qualities can also improve energy efficiency. For example, spray foam roofing both insulates the roof and provides a watertight membrane to keep out both moisture and drafts. 

3. Weight Load

Most commercial roofs are more than just the waterproof exterior. They can house equipment such as HVAC and ventilation systems, antennas, dishes, and other pieces of equipment. Then there are weight concerns from weather events like snow and ice storms. The roofing material you choose needs to be able to withstand the maximum weight it could be expected to hold. 

4. Maintenance Needs

Flat commercial roofing can last for years, but it will need maintenance on occasion. Understand the basic maintenance needs and schedule for whichever material you go with. Membrane roofs may require puncture repairs or seam sealing, while asphalt and bitumen roofs may require periodic roof coating. Comparing the lifetime maintenance costs can aid the decision-making process.  

5. Life Expectancy

Everyone wants a durable roof, but there may be options available to increase durability and life expectancy. Membrane roofs, for example, can be installed with wind-resistant strapping that will prevent uplift, blow-offs, and roof wrinkles. When reviewing each material, compare the average lifespan in relation to the other deciding factors like climate suitability and maintenance.
