The term roof restoration can be used for any type of roofing repair work; even having a few missing shingles replaced can be considered a restoration project. However, many roofers use the term roof restoration to refer to a coating that is applied over a home's current roof, which then seeps into cracks and crevices, hardening and forming a watertight layer.
If you're thinking of having this work done on your home, only a roofer can answer specific questions you might have about your home's roof and its current condition, but note a few other commonly asked questions about a roof restoration of this type. This can help you determine if it's the right choice for your home.
How long does the coating last?
There is no easy answer as to how long a roof restoration lasts, as this usually depends on the condition of the roof itself. A roof with lots of missing shingles and that has softened and weakened over the years may not provide the best foundation for this coating. Also, if your home is in an area with high winds, heavy rains, and lots of hot, direct sunlight, this can shorten the lifespan of the roof restoration.
This doesn't mean you should avoid getting this work done, however, as an extreme climate would damage any roofing surface! The coating will also protect the home from water leaks, mould, and other such damage.
What is the difference between a roof restoration and paint?
Paint that is meant for a roof will need to be very strong and durable, so it doesn't fade, chip, or peel away, even when exposed to harsh weather conditions. However, roof paint is not typically meant to seep into cracks, holes, chips, and other damaged areas of the roof, and then harden to fill those areas and create a watertight seal. A roof restoration is meant to protect the roof and cover over damaged areas, not just restore its colour and appearance. If your home's roof needs a bit of a facelift, paint can be the right choice, but for a damaged roof, and for added protection of the roof, opt for an actual restoration.
Can it be used over any roofing material?
Only a roofer can tell you if a roof restoration material can be put over your home's roof, but note that it may not be the best for broken clay tiles or chipped metal pieces, or other roofing materials that might tear the membrane itself. Otherwise, it can usually be added to virtually any roofing material.
