With every year that passes, a growing number of homeowners choose metal for their roofing. Thanks to average durability of 40-50 years, energy savings, and minimal maintenance cost, there is no other roofing material that measures up against a metal roof structure for your commercial or residential building.
Similar to any construction project, you may have some questions and concerns regarding the roof application procedure. Don’t worry, we’ll cover the most common ones in this report.
A key factor to consider when you get a new standing seam metal roof is to hire an established expert with skills and experience in applying metal roofs. Similar to typical shingle roofs, improper installations and lower quality work can result in functional and aesthetic problems.
A roofing expert with proven qualifications and skills in metal roofing installation will be able to help you pick the right roofing structure for your home and pocket.
Finding a skilled and reputable roofing expert is equally important to select the most suitable material for your new metal roof.
After speaking with and hiring your roofing expert, they will be able to address any questions you may have in regards to the roofing procedure. Meanwhile, here are some basic considerations to note during the application of a new metal roof.
Metal Roof Set-Up Ways
Installations of metal roofs are split into two categories: new constructions and retrofit. In the first case, the application of metal roof layers takes place when the building skeleton is finished. Very often, the general contractor expects the roof application because the shell should be waterproof and the internal polishing phase can start.
In the case of retrofit work, your roofing expert has 2 main choices: to recover or overlay the roof or detach and replace it completely. The first option keeps the current roof untouched and prevents the need and expense of detaching and removing the previous roof and its secondary parts.
Keep in mind that in some cases, the recovery/overlay method is not a suitable choice and your roofing expert may suggest the method of full replacement. There are several factors involved in making this decision but there are a couple of common reasons why this option is preferred.
Local construction standards often determine if a removal/replacement job is necessary. Most local authorities will let you recover installations for one or two current shingle layers. If the number of shingle layers is more than that, the current roof will have to be detached completely.
Also, if there is widespread leakage occurring in the current roof which results in impaired wood decking, the entire roof will have to be detached and replaced. You may ask your metal roofing expert to perform a thorough check and look for signs of water leakage.
In most cases, the less damage your existing roof shows, the quicker your roofing project will finish and the lower the cost will be.
Metal Roof Installation Units
The following are the main units used in the application of a new roof.
This refers to the element that is used to shield the joists and rafters such as planks, plywood, or OSB boards. This is attached over the roof structuring compartments to generate a roof layer for underlayment and metal layer application.
The majority of contractors use artificial underlayments which provide several perms compared to felt papering ( an older version of underlayment). Synthetic underlayments are also quicker to set up, provide better durability, and can be exposed to climate settings for longer.
Metal Roof Panels
Metal roof panels come in several sizes and shade options to choose from and for every home style and pocket. Your metal roofing provider or expert can help you decide which is the best choice for your needs.
Closures & Clips
Based on the kind of metal panel you choose, your roofing expert will utilize closures and clips to apple the roof panels to the decking layer.
Flashing & Trim
Flashing & trim is about the compartments that are applied at the areas and edges of the metal roofing structure to shield the roof and stop water from getting into the roofing structure and building lines.
Adhesives & Caulking
Butyl tapes and sealing agents are applied to metal intersections e.g. laps or junctions that link to panels.
The adhesive must stick to the painted metal layers and offer some elasticity for motion as the metal stretches and/or shrinks with the shifting climate conditions.
