Foam roofing (also spray polyurethane foam) is a highly dense material that comprises polyurethane foam and elastomeric coating. Once your roofer installs the foam on your roof surface, the foam expands and creates a solid, seamless layer that offers superior protection against harsh elements.
Read on to discover the incredible benefits of foam roofing systems as you explore your roofing options.
Improves Energy Efficiency
To measure a roof's energy efficiency, contractors use a technique known as the R-Value. A spray foam boasts a high R-Value of about 6.25 per inch. The higher the R-Value (resistance to heat flow), the greater your roof's insulation ability. Hence, very little heat or cold air can pass through the thermal envelope.
With a foam roofing system, your home or commercial building doesn't lose heat during winter or cool air during summer. So, your HVAC systems do not strain to maintain comfortable indoor temperatures, which saves you money on energy bills.
Provides Waterproofing Properties
If you use a sealant susceptible to cracks, water eventually seeps into your building and traps moisture that can cause mold growth. Luckily, such issues become a past concern when you install a foam roof.
Firstly, contractors install a spray foam roof as a continuous layer that creates a watertight and airtight seal with no joints or seams. The foam then expands and seals all nooks and crannies on the roof, which eliminates all potential leak points. To put it simply, your new roof becomes leakproof.
When properly installed, you will not experience water ponding issues on your roof, as is common with flat roofs. So, your roof will be safe from cracks, leaks, and other water-induced damages. To achieve this, contractors usually add some thickness in low areas, so water drains from your roof and into the gutters without pooling.
Allows Easy Installation and Maintenance
A major upside with a foam roof is that you can apply it on new or existing roof materials like metal, shingles, or concrete. Since spray foam begins as a lightweight liquid, your roof installation expert can apply it even on irregular-shaped roofs (like a domed roof). Hence, you don't need to tear off your old roof and start from scratch, which ultimately saves you money on installation costs.
Also, foam roof maintenance is often a breeze. If you notice any cracks or holes, you can use caulk to fill these dents. You may also opt to recoat the affected areas on your roof if you like. With these steps (along with regular professional inspection), your roof can last for 20 to 50 years.
Given all the benefits, a foaming roofing system is worth every penny. But that is only possible if you enlist a qualified roof installation expert to install your roof properly so you can get the most out of your new roof.
