What goes over your bare wood roof decking when your home is re-roofed?
Once the old shingles and underlayment are removed and the decking is exposed the wood is inspected for damage. Wood is then replaced as needed and new underlayment is installed which is called “Dry In”. Either Felt Paper or Synthetic underpayment is then installed prior to the shingles being installed.
Tar or felt paper is the traditional and “old school” underlayment used under shingles for over 100 years. It was a good product and provides some water resistant properties should you have shingles come off and leaving the roof exposed. It can and WILL break down, crumble and even rot in time so it’s not a totally weather proof product. This is especially prevalent in Florida with the high temperatures that we experience. It’s not the best choice for roofs with direct southerly exposure or shallower pitch roofs as it will break down faster under the shingles than synthetic underlayment.
Synthetic underlayment such as GAF FeltBuster is the new and improved underlayment system. It is made of a polypropylene material that has much better water resistant properties with some even being waterproof and manufacturers stating that a roof can be left covered in synthetic alone without shingles being installed for up to six months. Felt paper is a petroleum product that dries out and disintegrates over time leaving the roof vulnerable to leaks eventually.
Which Are Better: Three Tab or Architectural Shingles??
Architectural (also known as dimensional, laminated or composite shingles) shingles are constructed with a heavier base mat which multiple layers of material are adhered to. This gives the “dimensional” shingles a layered or three dimensional look. Whereas the standard three tab shingle contains a flat layer with no dimensional “thickness” to it. Typically architectural shingles weight almost 50% more than the standard 3 tab shingles.
Dimensional shingles were developed in the 70’s for the high end home market. Laminated shingles do a much better job hiding imperfections in the roofing structure as well. Architectural shingles typically have a minimum of 25 to 30 year warranties. Because of the heavier construction they are less likely to warp and they provide much better wind resistance. Standard three tab shingles are typically rated for 60 mph winds while most architectural shingles are rated for 80 mph up to 120 mph.
Do your research!
It’s important to hire a local roofing contractor with plenty of first-hand experience handling roofs in your specific area. Your location, climate, and environment can impact the performance of your roof. In a humid climate, for example, your roof could be more prone to algae growth and moisture-related shingle damage. In a sunny environment, you’ll have more trouble with discoloration and heat absorption. This is why you should only work with a roofing contractor that you trust.

Why is it important to keep debris off your roof??
Your roof is one of the most protective elements of your home. It protects building materials beneath the roofing and keeps your belongings inside safe from water leaks. The debris from the roof in this picture caused the hole in the pool enclosure. Keeping your roof free of any type of tree debris, leaves and limbs as well as keeping gutters clean not only improves the appearance but also maintains the integrity to make your roof a longer lasting product.
One of the most common places for a leak in your roof is the chimney.
One of the most common causes of chimney leaks is the chimney cap. The chimney cap protects the top of your flue from water entry, as well as animals and debris. Also, if flashing is incorrectly installed, damaged, or merely loses its seal due to wear and tear or age, water can easily seep through any gaps. You should have your roof and chimney inspected after every major storm and at least once or twice a year.
