Flat Roofs

Servicing a flat roof requires a different set of skills and knowledge of materials than that of a pitched roof. Macomb Roofers is certified and experienced in flat roofing replacement and repair. Our roof repair experts have successfully serviced flat roofs throughout the Macomb area. There are many reasons you might need to have your residential or commercial flat roof replaced or repaired, such as water, ice, snow, or wind damage. Flat roofs are built up of layers of roofing felt and tar. Leaks usually occur at low spots or where the roofing felt has been damaged. Macomb Roofers knows how to quickly locate the leak and repair the damage to the roofing felt and mend any blisters where the top layer has separated.

Some people believe that servicing a Flat Roof doesn’t necessarily require a professional Roofer. They think that because the roof is flat there isn’t the same risk of injury. Macomb Roofers knows that no roof is risk free.

Macomb Roofers has experienced roofing professionals that have been in the business for years. They have the proper tools and knowledge needed to do the job correctly. For example:

Roofing felt and tar are very flammable, if heat must be applied to dry out the area before repairs can be made, they the proper equipment and know not to let the felt layers get hot enough to burn or bubble;

Metal flashing is used to seal out water around the chimney, at vent pipes, along the valleys where two roof pitches meet, and sometimes over exposed windows. Macomb Roofers knows that the replacement flashing must be EXACTLY the same type and diameter as the old one or the potential for leaking remains;

  • Edges of metal flashing are extremely sharp and it is imperative to wear work gloves whenever handling metal flashing;
  • The metal flashing for chimneys on a flat roof is different from that on a pitched roof and requires the correct parts;
  • To climb a ladder in the winter one must have the proper clothing and foot-wear to prevent frost-bite and injury.
  • Don’t underestimate the challenges of maintaining and repairing your flat roof. Contact the experts at Macomb Roofers and let them handle the job for you.

In addition to the requirements of servicing a flat roof, there are also the different materials that are best suited for flat roofs to take into consideration:

  • Structural concrete is an excellent choice with flat roof constructions, of which there are three main categories:
  • Precast/Prestressed (Most popular concrete selection) including:
  • Double tees – for short spans up to 60 feet (18 m);
  • Hollow-core slabs – when there is a need for flushed ceiling;
  • T-beams (similar to double tees) used for spans ranging from 30 feet (9.1 m) to 100 feet (30 m);
  • A combination that uses prestressed joists with prestressed planks includes:
  • Keystone-shape joists – for up to 36-foot (11 m) spans;
  • Tee-shape joists – for up to 60-foot (18 m) spans.
  • Cast-In-Place;
  • Shell.
  • Concrete or fiber cement, which is usually reinforced with fibers of some sort, is another option.

Alternative Flat Roof Options

Rock roofs are inexpensive to install and the material is recyclable. Macomb Roofers can complete your roofing project in a shorter time frame because the insulation and other layers of the roof do not have to be fixed to the roof substrate using adhesives or other material. Instead the entire system is pinned to the roof substrate using the rocks or one-inch diameter gravel as ballast. Instead of gravel ballast, some newer rock roofs have pavers or even garden soil, making it easy to walk on the roof or have a roof garden and patio. Maintaining a rock roof is also easier as it is possible to simply remove the pavers and fix any problem with the underlying layers. The rock roof is also fire proof.

Membrane roofing. Membrane roofing consists of large sheets, generally fused in some way at the joints to form a continuous surface.

Thermoset membrane (e.g. EPDM rubber) are Synthetic rubber sheets adhered together with contact adhesive or tape. The primary application is for large open areas, such as a “big box” store.

Thermoplastics (e.g. PVC, TPO, CSPE) weld plastic sheets together with hot air, creating one continuous sheet membrane. Typically they can be re-welded, with the exception of CSPE. Because of its hot-air weldability, this material lends itself well to both “big box” and small roof applications. This membrane is installed by two methods: 1.) Rolls of membrane are attached to the ridged insulation using a bonding adhesive; 2.) The edge of each roll is fastened through ridged insulation into structural deck, and the proceeding roll is lapped over the fasteners. The overlap is then heat-welded with hot air to create a mechanically fastened thermoplastic roof.

Liquid roofing and Asphalt roll roofing including single and double coverage types are also available options.
