Title: When is Roof Repair Mandatory?

When is Roof Repair Mandatory?
  • Roofs can require repairs for a wide variety of
    reasons. When roof repair becomes mandatory,
    youll need to consider getting your roof fixed
    before other problems start to happen. If you
    dont act quickly, you might wind up with total
    roof failure. That means youd need to replace
    your entire roof, which is both costly and
  • To avoid having total roof failure, well cover
    some of the most common issues that require
    mandatory roof repair. By providing you with the
    knowledge necessary to know when youll need to
    perform a roof repair, youll be able to extend
    the lifespan of your roof and save yourself money
    in the process.

Roof Punctures
  • Roof punctures call for a mandatory roof repair.
    Unfortunately, essential wear and tear on a roof
    create roof punctures. Roof punctures arent easy
    to avoid. They tend to happen to even the
    highest-quality roofs over time.
  • Roofs can be punctured when people walk on the
    roof. The more high-traffic the area of the roof,
    the more problematic the area will become. If you
    have a spray polyurethane roof or a single-ply
    roof system, you are far more likely to
    experience roof punctures.  
  • To repair a roof with punctures, youll want to
    call in an expert to not only improve the
    perforations but also have a walkway added to the
    ceiling. The new path will help you avoid
    additional punctures in the future. Another idea
    is to add an extra layer or two of the membrane
    because this can also help prevent future issues
    with roof punctures.

Roof Shrinkage
  • Roof shrinkage is another issue that will require
    mandatory roof repair immediately. An experienced
    roof technician can recognize evidence of
    contraction by merely looking at the roof.
    Typically, shrinking occurs on the field
    membrane, and that can pull on the roof
  • Deterioration is also usually a major cause of
    roof shrinkage, and this happens over time with
    wear and tear. Its important to remember that
    every roof is different and comes with individual
    specifications. Thats why youll want to make
    sure you hire a professional roofer to assess for
    roof shrinkage and offer a solution.

  • Blow-offs are another problem that calls for
    mandatory roof repair. When seams and flaps start
    to open because the flashing is no longer
    connecting correctly, a blow-off is likely to
    occur. Blow-offs happen when the connected
    flashing is either poorly installed or wears out
    over time. However, its imperative to make sure
    that the installation of the flashing happens
    correctly to prevent any future blow-offs with
    your roof.  
  • Sometimes, too few fasteners placed on the base
    sheet create blow-offs as well. When that
    happens, it means the gravel embedding
    experienced the incorrect installation.
    Inadequate installation of flashing often results
    in all types of code issues and can also open the
    door for more punctures in your roof.  
  • If you noticed a blow-off on your roof, then
    youll need to consider a roof repair
    immediately. You most likely need to have a
    professional increase the roofs wind uplift
    resistance, and a simple roof repair can assist
    with this procedure.

What are the Most Common Types of Roof Repair for
Water Damage?
  • No matter what type of roof system youve
    installed, youll need to plan for roof repairs
    at some point. Roofs commonly need
    reconstructions for a large number of reasons.
    Sometimes, youve had your roof for an extended
    period, and essential wear and tear requires some
    form of repair. Harsh storms and earthquakes also
    create roof repair issues times, as do tree
    branches breaking and falling on a roof.  
  • If you feel that your roof might need repair due
    to water damage, dont worry. There are several
    reasons why your roof might require assistance.
    Well cover below some of the most common reasons
    you might need a roof repair. That way, if you
    notice your roof experiencing any of these types
    of issues, you can address the issue immediately,
    before it becomes a significant problem.

Ponding Waters on Your Roof
  • One primary reason for roof repair is pooling
    water, which is typical that occurs more
    typically with flat roofs. However, sloping roofs
    can still experience pooling water issues. When
    water starts accumulating on the surface of a
    roof, it can cause significant damage if it fails
    to drain. Water commonly pools on a roof when the
    roof isnt designed correctly, or the roof is
    experiencing excessive wear and tear issues.  
  • Before repairing the roof, youll need to figure
    out why you have water pooling on your roof. By
    addressing the reason why water is pooling,
    youll then be able to reach out to an expert and
    ask for a repair.

  • There are a few common reasons why water might be
    pooling in areas on your roof. For example, you
    could have an HVAC unit that doesnt have a
    condensate drain line. Without that, youre more
    likely to get pooling water. Another common
    problem is the proper maintenance of the drain
    system itself. If you dont maintain your drains
    well, your drain might have debris blocking
    certain areas, meaning the water is blocked and
    cannot drain, so it pools on your roof.  
  • After you figure out the reason for the ponding
    water on your roof, a roof technician can assist
    you with a fix. An expert roof technician would
    also be able to assess the issue and run the
    cause of the pooling water by you before any

Roof Leaks
  • Roofs experience leak problems for a wide variety
    of reasons. For instance, if flashing fails to
    connect correctly during the roof installation
    process, then youre roof is built-up.
    Unfortunately, built-up roofs are much more
    likely to leak. Bitumen roofs can also leak when
    there isnt a well-developed moisture barrier
    below the coping cap as well.
  • Excess moisture can also penetrate a roof over
    time, through simple wear and tear. That usually
    happens when there isnt sufficient head laps and
    backwater laps in the roof. If leaks and blisters
    continue to occur with a roof, the roof will
    eventually totally fail. So, if you notice a leak
    or a blister, its time to talk to a roof
    technician and assess the issue so that you can
    repair it. That way, youll not only save your
    roof, youll also likely save thousands of

What are the Different Types of Flat Roofs?
  • When youre considering purchasing a new roof,
    youll need to take into account the fact that
    roofs take abuse over the years and that
    necessitates maintenance. No matter what type of
    roof you decide to purchase for your home or
    place of business, youll need something durable.
    While roofs offer options like sloped roof
    systems that help to shed water and snow, you can
    also consider purchasing a flat roof system.
  • Flat roof systems differ from sloped roof systems
    because flat roof systems provide low slopes,
    usually between ¼ and ½ per foot. Flat roofs do
    not shed water as efficiently as sloped roof
    systems. So, flat roofs offer designs that are
    feature a monolithic roof surface made to handle
    standing water for some time.  
  • When it comes to flat roofs, there are three
    major types of systems to consider. First, there
    are membrane or single-ply roofs, like Ethylene
    Propylene Diene Monomer (EDM) roofs. There are
    also Built-up Roofing (BUR) options and Modified
    Bitumen Roofing choices. Well cover each type of
    roofing system in more depth below.

EPDM Roofing
  • As the latest in flat roof technology, EPDM
    roofing is a popular choice. There are a few
    similar options available on the market today
    that are similar to EPDM roofs, but EPDM roofs
    are the most commonly used for residential
  • EPDM roofings popularity is on the rise because
    it is an environmentally friendly roofing option
    since EPDM roofing material is of recycled rubber
    materials. Those rubber materials help create
    insulation for a homes roof and attic, bringing
    down the overall costs of cooling and heating a
    house. That means EPDM roofs are also
    economically friendly for people that purchase
    them. EPDM roofing shingles also come in a bevy
    of different texture and color options, so they
    can make even the pickiest person happy.

Built-Up Roofing (BUR)
  • Built-up roofing used to be the most popular type
    of flat roof system until the invention of
    single-ply roofing and modified Bitumen emerged
    onto the market. When using BUR roofing, tar and
    gravel make a watertight layer on the roof,
    waterproofing the roof. There are several
    benefits to using BUR roofing and creating this
    type of waterproof system. First, BUR roofs last
    a very long time and are known to be durable. The
    use of gravel and tar makes the BUR roof very
    resistant to damage. However, because of its
    durability, it also costs quite a bit more money
    than some of the other options.

Modified Bitumen Roofing (MBR)
  • While BUR roofs offer a lot in the way of
    durability, some people prefer the option of
    modified bitumen roofing instead. BUR roofs are
    often messy and costly to install, which led to
    modified bitumen roofing to respond to some of
    the issues with BUR roofs. Modified bitumen
    roofing first emerged onto the market in the
    1960s, offering a few modifications to the BUR
    process. With an MBR roof, a person can now get
    the durability of a BUR roofbut use roof wear
    layers and cap sheets to cut back on mess and
    make the roof system even more durable.

Whats the Difference between a Flat Roof and a
Sloping Roof?
  • When it comes to roofs, homeowners usually pick
    between two different roofing styles. Either they
    select from a steep-sloped (or pitched) roof or a
    low slop (or flat) roof. Depending on the type of
    roof you have, youll need one or the other. If
    your roof displays a steep slope to it, then you
    have a steep-sloped or pitched roof. However, if
    you have a roof that looks pretty parallel to the
    ground, then youve got a flat roof.  
  • Flat roofs arent flat by design even if they
    sound like they might only be flat. Even a flat
    roof offers some slope for drainage. However,
    there are still differences between a flat roof
    and a sloping roof as far as maintenance concerns
    itself. So, well be breaking down some of the
    differences between the two below.

Flat Roof Vs. Sloping Roof Uses
  • Youll find both flat roofs and sloping roofs on
    residential and commercial buildings. Regardless,
    flat roofs tend to be more common on commercial
    buildings, and sloping roofs are found more often
    on residential buildings. Commercial buildings
    tend to utilize flat roofs. Flat roofs allow them
    to mount different things on their roofs like
    solar panels, refrigeration equipment, and other
    items. Thus, a flat roof tends to offer more
    flexibility than sloped roofs.  
  • On the other hand, if a person wants solar
    panels, they arent only limited to flat roofs.
    Sloping roofs can also have solar panels. Many
    residential homeowners add solar panels to their
    sloping roofs regardless. Still, flat roofs are
    typical even among residential buildings because
    they are far more aesthetically appealing than
    sloping roofs.

Flat Roof Vs. Sloping Roof Materials
  • Sloping roofs feature all different types of
    materials. For instance, sloping roofs use
    everything from clay to concrete for construction
    purposes. These materials allow for more
    affordability while still offering the necessary
    long-lasting durability any homeowner would need
    from a roof. Some other materials used for
    sloping roofs include asphalt shingles, wood
    shake, copper, and galvanized steel. 
  • Flat roofs, on the other hand, offer a different
    type of diversity when it comes to materials. The
    materials used to make flat roofs tend to be less
    well known than those used to make sloping roofs.
    Flat roof materials include things like built-up
    roofs for durability and heat protection. Many
    built-up roofs also feature a top layer of gravel
    and small rocks on top of a thick seal of asphalt

  • Sometimes, flat roofs also use Polyurethane Spray
    form as a material. These types of roofs are
    light in weight, simple to install, and the spray
    liquid allows for quick application and setting.
    Plus, spray foams are often durable and prevents
    leaks since the chemicals bond to the roof,
    making the roof difficult for water to penetrate.
  • As a material, spray foam is very popular for
    roofs that are commercial or industrial. Youll
    commonly find spray foam used as a material in
    flat roofs for places like warehouses. The spray
    foam helps to insulate the roof, keeping the cost
    of electricity and power down and covering the
    interior of the building well.
