Types of Roof Flashing

Wherever two or more parts of the roofing, such as two slopes, intersect and wherever the continuity of the roof is broken by components such as skylights or chimneys, the risk of leaks and other roofing problems increases, that’s why flashing has been invented. Roof flashing is reinforcement consisting of stripes of strong material installed by conscientious Pensacola roofing contractors in the sensitive areas with the purpose of ensuring the strength of the roof and to prevent the formation of leaks. Here are the most common flashing types:

  • Types by structure – the two types of flashing stripes from this point of view are exposed and concealed stripes. Exposed flashing is used for preventing the penetration of water from the outside, while concealed flashing collects the water and directs it away from the structure through drainage holes;
  • Types by material – the most common materials used for flashing are galvanized and stainless steel, aluminum, lead, copper, bituminous sheets, plastics and rubberized sheets. Exposed flashing is usually made from metal alloys, while concealed flashing more commonly uses membrane-like materials, such as bituminous sheets. In some cases, a combination of two materials, such as galvanized steel sheets covered in bitumen, is the best solution for avoiding corrosion in areas where the flashing comes into contact with mortar.

Can You Finish a Roof Replacement in Rainy Weather?

Most roofing jobs need to stop when it starts raining – even if you are desperate to get the project completed, you will need to accept that rainy days cause delay. Safety conscious Pensacola roofing contractors will stop work if rain starts and so should you if you have decided to do some roof work on your own. However, there are several good ways to maintain efficiency and safety, whatever weather comes along: Check the long-term forecast as well as for the next few days before you start any roofing project – weather forecasts are not always 100% reliable, but they can give you a clue about the chances of getting rain while your roofing project is under way; Removing only as much of the old roof in one go as can be replaced during the day – while removing the entire old roof and proceeding to the installation of the new material only afterward seems like a good idea, good roofers do not remove more of the old material than they can replace in one day; Having large sheets of fo...

How to Inspect Your Roof After a Storm

Image
Storms may happen in any season and require a roof inspection, to make sure the bad weather did not cause damage. Water infiltration under the roof indicates that somewhere the roof is damaged. However, not all leaks are as obvious as you may think, as wet stains that appear on the ceiling are not necessarily exactly below the roof area that allowed the infiltration. The roof will need to be checked both inside and out. Depending on the type of roof, verify if there are displaced covering materials, cracks or uncovered spaces. In addition, check the gutters and downspouts; they must not have loose, deformed or cracked elements. The area under the eaves must also be in good shape, with no visible damage. Last but not least, pay close attention to checking the areas around skylights or dormer windows, chimneys, roof vents, solar panels mounted on roofs, satellite dishes etc., as they are generally the most vulnerable and favor most water infiltration. If you have an old roof that ha...

The building component that is usually the most severely affected by hurricanes and storms is the roof, therefore local building owners need to be very careful when choosing the right material for their roofs.
