House design is a complex process that requires a lot of responsibility. It is essential to choose reliable and high-quality building materials during this process because they will affect the final result. Not only the foundation, walls, or floor of the house are essential, but also the roof. A Registered Roof Observer (RRO) is a certified professional who observes and reports on roofing system conditions.
This is the most critical component that can give you a real headache. Knowing that the roof is a costly product, we must choose it carefully and consider factors such as price, manufacturer, appearance, material, color, and durability. Let's review what Registered Roof Observer recommends these days.
Used materials
Construction materials guarantee a house in good condition, but they can also represent maintenance and remodeling expenses that you must consider. Wood, for example, is an expensive material and difficult to maintain.
Good quality concrete for roofs is durable and reliable. Still, if some low-quality materials were used in construction and the property is familiar, you may be dealing with more severe cracks or leaks daily.
Consider this information when a Registered Roof Observer visits to evaluate the home and determine its overall condition.
Quality and condition of the finishes
The finishes are those details that you can examine more closely. Registered Roof Observer observes the conditions and roof details and more. This can give you an idea of the changes you must make if you purchase that house.
Despite minimal details, the finishes are critical to keeping a house in good condition since they are objects that could represent a small but constant expense in case you have to replace them or give them a lot of maintenance.
Evaluate waterproofing: roof preparation.
For best results, evaluation is performed by a professional Registered Roof Observer. After assessing and designing the waterproofing, the client will have the peace of mind of a job well done. If something goes wrong, you can also take advantage of the applicator's warranty.
In this case, the following products are used:
Sealant
According to the evaluation of the roof's waterproofing, the sealant used reinforces polyurethane putty. Without a doubt, polyurethane putty has a low modulus of elasticity for sealing joints and active cracks. It is also for use in high-humidity conditions. Additionally, it is formulated to avoid bubbles during even in conditions of high temperatures and humidity. In fact, its excellent thixotropy allows its use even in large expansion joints. With a movement accommodation factor of 50% and excellent adhesion. Even on supports such as aluminum, iron, and polycarbonate.
Primer
An epoxy primer is used. First, the surface is washed under high pressure using degreasing detergents. Evaluation of the waterproofing job indicates the need for correct priming.
Reinforcement membrane
A liquid polyurea/polyurethane membrane is used. At the same time, in three layers and all the joints between metal roof pieces. Also, in the flashings, seal the holes. Additionally, it is applied to the inside of the gutters.
Surface waterproofing
Finally, the waterproofing layer is applied over the primer. Without a doubt, a polyurea-based polymer – polyurethane with a minimum of two coats on the surface of the roof sheets is the best solution. By the way, it is applied in layers of different colors to set 100% coverage.
