As with any roofing material, there are benefits and drawbacks to consider before installing roll roofing. On the plus side, roll roofing is budget-friendly, lightweight, and comparatively easy to install. It is also ideal for low-sloped roofs and lasts around 10 years. The cons of roll roofing, however, include its low durability compared to roofing materials, restricted color choices, and low ROI.

Pros:

• Low-cost

• Lightweight

• Cut to size

• Easy and quick installation 

• Designed for low-sloped roofs

• Waterproofs your roof for an average of 10 years

• Easy to purchase and transport

Cons:

• Less durable than asphalt shingles

• More prone to cracks and tears

• Short life span

• Not as many color or style choices

• Not as aesthetically pleasing as shingles, wood, or clay tiles

• Not preferred for a higher home resale value

A metal roof can last anywhere from 15 to over 100 years, with an average of 50 years, depending on the material, installation, and environment. The specific metal is a key factor: aluminum roofs may last 20 to 45 years, while steel can last 30 to 60 years. Tin can last for up to 75 years, and more durable options like zinc, stainless steel, and copper can last from 80 to over 100 years. Factors that can shorten a metal roof's lifespan include living in a coastal region with corrosive salt air, improper installation (such as laying over old shingles), and failing to inspect and replace fasteners, which may wear out before the panels.

Rubber shingles last for around 30 years, on average, and some can last for and include warranties for up to 50 years. Rubber roof shingles are more expensive than asphalt shingles, but they can last up to twice as long, meaning they provide more value in the long run. Just keep in mind that rubber roofs often require more maintenance than asphalt shingle roofs, including routine cleaning to avoid mold growth. Ask the roofer who installed your roof for an estimate for routine cleaning, if necessary.

The best material for your shed roof depends on your budget and personal preferences. For instance, if you’re looking for the most cost-effective option, rolled roofing is your best bet. Just be aware that it only lasts for five to eight years. If you prefer something with a longer life span (and you’re willing to pay for that durability), consider slate shingles, which can last for hundreds of years.
