A metal roof can be a wonderful choice for homeowners across the country. Not only do these roofing materials make for a more efficient and hazard-free lifestyle, but they are also beautiful when installed correctly. However, metal roofing supply companies urge that installation requires a keen eye for detail, and there is certainly room for error. The following mistakes usually happen on behalf of the roofing contractor, so it’s crucial that you understand what to do and how you can best avoid installation issues down the road. 

5 Roofing Errors Your Local Metal Roofing Supply Team Wants You to Avoid

1. Watch for Incorrect Lapping 

Lapping metal panels means setting them down side by side and on top of one another to ensure sturdy construction. Each piece has a large and small lip that must be in the correct placement for the roof to be safe. The shorter lip should always cover the fatter part completely. 

2. Set Screws Correctly 

Screws that are too tight are a safety hazard as they can strip the material underneath and become ineffective, allowing the material to slip and slide. Make sure each of your screws is fastened securely and that the washer is a bit loose. 

3. Use Your Sealant Wisely

Many roofing contractors assume they can use sealant or caulk to cover up areas of the roof that have extra space between the panels. In addition to being dangerous, this may lead to an expensive repair down the road. Make sure the pieces are aligned and set correctly and use your sealant only to further waterproof the bonding between sections. 

4. Monitor Panel Length

Panels that are too long extend up to five or six inches past the edge of the roof. Make sure each section goes only about an inch or two past the ends of the roof. 

5. Secure Pipe Flashing

Pipe flashing is effective for keeping water out, but many contractors assume the job can be done with a few screws and a bit of sealant. Instead, secure the flashing with a layer of caulk beneath the surface of the roof and an added boot secured with screws around its perimeter. This ensures water and sunlight do not wear out the protective materials and your roof remains as safe as possible.
