While the installation of a waterproofing membrane is normally considered an underlayment that is attached to the roof sheathing, under the finished roof material, some folks select to utilize the membrane as the finished roof surface, without other roofing products installed on top.
Some homeowners that have roof leaks and want a guaranteed solution have a difficult time envisioning how their finished roof surface will appear following the installation of a waterproofing membrane.
The finished roof appearance depends on several factors; such as the architectural style, the roof pitch and the front elevation of the house.
With certain architectural styles, the roof surface is less visible, and therefore the finished appearance is not as important as a house that has a very visible roof surface.
For instance, with this Tudor style of architecture in Heredia, the roof is hardly visible and therefore the finished roof surface is less of a factor.
After the installation of a 5 mm thick, white membrane, the roof is less visible, as the new white surface blends well with the similar colored moldings.
Additionally, the surface of the white colored membrane reflects the maximum amount of the suns radiation and keeps the interior of the home cooler
With different architectural styles like this traditional ranch in San Ramon, with a tile profile metal roof, the surface is very visible and becomes a major part of the overall architectural style.
After the installation of a 4 mm thick, terracotta membrane, the roof appearance stays the same as before.
Homes with contemporary architecture usually have simple, straight lines, with the roof surfaces exposed and an integral part of the overall design. The home in the photo below in Grecia, had a green metal roof, and the owners were not only looking for a waterproofing solution, but they wanted additional thermal and sound barriers
We installed a 5mm thick, white membrane and then the owners decided that the white surface was not what they wanted and we covered the white membrane with a terracotta colored acrylic sealer.
With this Beach Style Architecture in Guanacaste, the roof surface blends in with the ornate moldings and the roof becomes an integral part of the overall design.
Whichever architectural style you have, there are various colors and application methods to make your roof look different, or maintain the same appearance
