Re-Roofing A Low-Slope Roof In The Champions Area
The Need To Know About Re-Roofing A Low-
Slope Roof In The Champions Area
The Do’s And Don’ts Of
Are you interested in knowing more about re-roofing residential low-slope roofs in the Champions Area?
Residential low-slope roofs are different from your typical roofs. They don’t have the typical slope and, therefore, come with some quirks that homeowners must be aware of.
At Houston Roofing & Construction, we install low-slope roofs with outstanding precision.
We’d like to share some information with you about things you should know about re-roofing a low-slope roof.
Let’s dive in.
What is Re-Roofing For Low-Slope Roofs?
The first topic to discuss is what re-roofing actually is. Re-roofing is the process of installing a new layer of roofing material on top of an existing layer without removing the underlying layer first.
Re-roofing is actually quite common, and it’s typically done with shingles but is done with other materials as well. Contractors sometimes won’t recommend a roof replacement until after a second or even a third layer has been applied to the roof.
Now, to be more specific, in the state of Texas, a building is only allowed a maximum of two layers of roofing. This regulation is according to the Residential Code in Texas.
As a note, there are exceptions to this based on special circumstances—also, the regulations on roof layering are primarily due to fire safety concerns.
So what does this all mean for you?
It means that re-roofing is an option for homeowners who don’t want to go the route of a roof replacement at this current time.
Re-Roofing Shingles On A Low-Slope Roof
Asphalt shingles are not typically a first or second choice for low-slope roofs and aren’t used if a roof’s slope is less than 2:12. However, they are used sometimes and, if so, can run into many problems.
A re-roofing project relies heavily on the work done by your previous roofer. If your shingles are nailed over, your current contractor will have to depend on the work done beforehand.
For example, something like your roof’s flashing could have been installed poorly the first time, worn out over time, or been damaged. If any of those scenarios are true, re-roofing will likely worsen those problems.
When the re-roofing process happens, your contractor won’t be able to inspect your roof decking.
Your roof decking is crucial to the health of your roof. It’s the foundation on which the roof is built. Re-roofing is essentially nailing over the old shingles with new ones, so there’s no opportunity to see what’s happening under the older shingles.
When re-roofing, you might run into warranty issues, either from the manufacturer of the shingles themselves or from a contractor. Choosing a different type of shingles than the ones already installed on your root can cause an improper fit, leading to warranties not holding up if damage or leaks occur.
The last thing you want is to risk voiding your warranty or having issues down the road because of a roofing choice you made, unaware of the potential pitfalls.
Other materials are far better for low-slope roofs, and not only are they better for initial use, but some can be used in re-roofing to a more desired effect.
Low-Slope Roofing Materials
Low-slope roofs are built with a variety of materials.
Asphalt shingles have problems if the roof’s slope is too low, which is why other materials are commonly used.
Other materials typically and more commonly used on low-slope roofs include metal and membrane roofing systems.
Standing seam metal roofs are popular for low-slope roofs based on their sleek aesthetic and extended lifespan.
Membrane roofing systems come in different types, including thermoplastic polyolefin (TPO) and polyvinyl chloride (PVC).
These single-ply systems are often used commercially but also for residential roofs.
If you’re looking to re-roof instead of getting a roof replacement, you should first contact a trusted contractor to inspect your low-slope roof.
Depending on the materials your current roof is built with, there might be better options for your home than re-roofing.
