When it's time to make a decision on your next new roof, what's going to be the driving force? Is it budget? Type of roof system? Or warranty length?

What if you could get all three? Materials and labor cost have been stable over the last few years so that will help with the budget. 

Built up roofs (BUR), modified bitumen membrane systems, and single plies are all good choices and each will have great performance if installed by a qualified contractor.   

Warranties are available for anywhere from 10 to 25 years and generally speaking the longer the term required the more robust the specification is and consequentially the higher the cost.  

To find the right combination of price, roof type, and warranty length call your local branch of Service Works, Your Full Service Roofing Contractor.

The 20 Year Roof
In the past several decades, building owners have made decisions based upon terminology such as a "20-year roof." The implication was that your roofs could last for 20 years or more, and that if the roof failed due to ordinary wear and tear, someone would fix it at no cost to the building owner. When a new roof system is contemplated, the decision will be to select the lowest-cost "20-year roof" available.
The 20-year goal stems from the post-World War II era, when the dominant choice was a bituminous roof with asphalt or coal tar pitch as the waterproofing adhesive, pea-gravel as the surfacing to protect the bitumen from UV degradation, and felt reinforcing saturated with asphalt or pitch. For the owner, there was a 15-year choice consisting of three or four plies of felt or a 20-year system with four or five plies.
Energy, in those times, was relatively cheap, so if any thermal insulation was used, it was used mainly as a roofing substrate and might have been an inch of wood fiber, glass fiber, or perlite boards. The R-factor would have been around three or so. Flashings were not usually covered under the warranty, and since we could not retain the flood coat and gravel on a vertical slope, flashings might have consisted of mineral surfaced cap sheets or reinforced asbestos felts.

However, times changed. More and more buildings were air-conditioned by the 1950s and cellular thermal insulations such as polyurethane and polystyrene with R-values of 4 or 5 displaced insulation with lower values. By the years of the oil embargo in the early 1970s, codes were calling for R-values of 25-30 instead. At the same time, the asphalt and coal tar pitch needed for traditional bituminous roofs were in short supply, so innovation in reinforcements shifted buyers' attention to polymer-modified two- or three-ply systems. Most of the innovations were European in origin, modifying the asphalt matrix with APP (atactic polypropylene) or SBS (styrene butadiene styrene). The improvements also served to reduce costs significantly by shrinking the number of plies and replacing the flood coat with factory-applied mineral granules, reflective foils, or coatings.

Hurricane Season

Well it looks like we avoided the "big one" again this season. Although we have had record rainfall we did not have any named storms hit the state.

But as the 2015 hurricane season comes to a close it's time to have your roofs inspected and have any maintenance items taken care of so you can be worry free through the holidays. Inspections should include a comprehensive checklist of all of the major components of your roof, preventative maintenance where required, and a general cleaning of any debris on the roof. These preventative maintenance inspections are required by the manufacturers and will extend the useful life of your roof.   

To help with your roof inspections and maintenance call your local branch of Service Works, Your Full Service Roofing Contractor.
