Why Select a Flat Roof?


Up until not long ago, traditional corner, mansard, or gable roofs were built for low-rise buildings while flat roofs were specifically made for multistory residential homes and industrial facilities. As the building element market and technology have developed over time, they have made the way for flat roofing for individual residences. Private cottages or homes can then include the addition of a second or third floor and even an extra space in which to include a greenhouse or recreation area. These aspects have contributed to the popularity of the incorporation of modern construction materials and technologies in order to reduce residential construction costs while adding certain levels of durability and reliability. One flat roofing benefit is its simple and inexpensive nature. If pitched roof construction costs may cost from 20-50% of the total cost, a flat roofing investment is basically calculated based on the cost of upper floor strengthening. Visit our website: https://mckinleyflatroofrepair.com/ to get more information.

Ideal Flat Roof Material


Flat roofing building components should offer top-quality waterproofing of the complete structure. In current times, the materials utilized for flat roofing should meet the following requirements:

* Lightweight

* Durability

* Thermal insulation

* Chemical protection

* Biostability

* Acoustic insulation

* Solar radiation resistance

* Resistance to fire

* Flexibility in application

* Cost-effectiveness

* Durable quality

Flat roofing is comprised of an assortment of materials that offer your home dependable waterproofing in addition to providing an ideal microclimate. These are:

* Sealants and underlayments for dependable installation, offering tight joints as well as extra waterproofing.

* Drainage system

* Bitumen roofing system

* PVC membrane to make a reliable and durable layer for waterproofing

In this manner, common roofing materials such as bitumen, cardboard, and paper are replaced by more innovative flat roofing elements.

Flat Roof Types


Three common flat roofing types:

* Modified bitumen roofing

* Single-ply roofing (e.g., EPDM).

* Built-up roofing (BUR)

Single-Ply Roofing (EPDM)

Polymer membrane is in high demand in the US for flat roofing, having taken over as a leading component for decoration and building repair. Membrane roof popularity comes from their durability (possible life span of 40 years), easy adaptation to varied temperatures (low or high), attractive color palette, and high reliability.

EPDM rubber cladding is created using recycled rubber materials that are environmentally friendly. Asid from pure EPDM with a rubber base, materials for composite flat roof replacement can also be offered. Traditionally, their top layer is rubber and their bottom layer is made of flexible bitumen-polymer.


* Its increased flexibility (about 400%) and lower cost make it different from other membranes.

* Its coating is resistant to any weather condition.

* EPDM roofing has a service life of 30 to 50 years for durability.

PVC Membranes

Another flat roofing innovative waterproofing material is PVC membrane. PVC roofs are single-ply roofs composed of flexible polyvinyl chloride (PVC-P). Hot air welding makes sure of definite impermeability.

Principal Advantages

* Building coverings from PVC are both flexible and strong.

* An exceptional option for deformed and rough surfaces, membrane coatings have a high deformation capacity.

* PVC membranes comply with all fire safety requirements.

* High vapor permeability removes the chance of condensate moisture stagnation.

* Its lightweight quality can drastically reduce the load on the main structure.

* The covering process is simplified by the single-ply membrane.

* Installation simplicity provides possibility for repairs to be performed in practically any weather condition.

Built-Up Roof (BUR)


Built-up roofing (BUR) utilizes gravel and tar to make a waterproof layer upon the flat roofing. Among the most expensive roofing types for a residential building, it has various disadvantages and benefits:


* Simple repair or removal

* 10 to 15 year lifespan with appropriate repair and maintenance

* Various types of multi-layer roofing that suit many needs: ballasted and smooth asphalt, cold layer, etc.

* Superior protection against adverse weather conditions, ultraviolet rays, and water

* Low maintenance and operating costs during entire service life

* Use of gravel adds durability

Modified Bitumen


BUR had been the single option for 60 years. Early in the 1960s, Modified Bitumen, a brand new technology appeared on the scene. This coating type improved the established effectiveness of BUR, also adding layers that increase durability and strength.


* Utilized in rolls that overlap, creating areas that are large and seamless

* Available in numerous methods of application

* Requires little maintenance due to its durability

* Offers increased elasticity and flexibility at low temperatures

* Simplified set up

* Reasonably priced

* Offers durability better than that of BUR, with similar installation ease to EPDM



Among the most expensive roofing types, this might not appear to be the most effective or the safest option. This technique utilizes a coating in order to repel water, with one excellent benefit: they are seamless.

TPO Roofing Membrane


This kind of material is recommended for the construction of buildings that are complex, specifically – social and industrial facilities, such as restaurants, cafes, recreation centers, hotels, sports facilities, factory workshops, etc.


* Resistance to deformation at negative temperatures, flexible.

* Up to 50 year life span.

* Vapour-insulating properties, low water absorption.

* Fire-resistant chemical components.

* Anti-fungal components in membrane production technology

As explained, every one of the above types of flat roofing has specific benefits. In the selection process for residential or commercial building flat roofing, it is crucial to take the advantages and specifications of each solution into consideration. Prior to selecting a roofing material, it is wise to contact an expert who can assist you with the selection of the ideal solution for your project. A roof that is well made will endure for several years of no-worries use.
