Get matched with top roofers in Mendota, IL

Just like when you’re shingling a roof, you can install felt underlayment under a metal roof, but a synthetic underlayment like adhered ice and water shield is the best option. These use adhesives rather than mechanical fasteners, so you have fewer penetrations going through your roof deck and a lower risk of leaks. Ice and water shield is also easier to install because you don’t need additional tools or fasteners to attach it to the roof deck.

Whether a metal or shingle roof is better for you depends on your preferences. Standing seam metal roofs require little to no maintenance, but if you install a screw-down metal roof where the fasteners are exposed, the gaskets on the fasteners will dry rot and need to be replaced. Generally, screw-down metal roofs need to be re-screwed every 15 to 20 years.

Metal roofs are energy-efficient and have extended warranties, while asphalt shingles are less durable than most. They tend to lose color and get damaged over time, and absorb heat from the sun.

You may become so frustrated with the look of moss on your roof that you contemplate whether to clean or replace your roof. Fortunately, you don’t have to go as far as replacing it. After cleaning the moss, you can use a chemical solution to keep it away. For further protection, trim branches that overhang the roof, as fallen seed pods and leaves on the roof allow moisture to collect, encouraging moss growth. Consider adding zinc-coated flashing to the roof, too. As rain washes across the zinc, it leaves zinc particles behind that inhibit moss growth.

It’s possible for a roofing estimate to change after the initial assessment, but in most cases, it shouldn’t. There’s always the risk that something unexpected will happen that causes prices to go up, like discontinued materials or your roofer discovering previously hidden damage to your decking when ripping off the old roof. However, experienced roofers should account for these circumstances in their initial estimates. Roofing contracts are binding, so always check your contract for language about how and why your numbers could change.
