Best Roofing Shingles For Your Roof And Other Questions Answered
Every homeowner wants to know what is the best roofing shingles to go for when re-roofing or relaying their roof. The most popular roofing option are all asphalt based shingles. These shingles performance depends to a large extent on the quality of materials used as fillers. The amount of materials used, the way the filler and asphalt gel all make a difference on how well the product performs. The reinforcements used in the shingles and the granules used on the surface also play an important role. Most commonly found roofing shingles are either fiberglass or organic. The fiberglass shingles are resistant to fire and moisture. Organic shingles are not recommended in for many states and councils because they are susceptible to fire and moisture.
If you happen to live in areas with strong winds, then organic roofing shingles may be the best roofing shingles for your needs as they strong wind resistance and high tear strength. They can also be installed in areas which are very cold. Whatever shingles you opt remember to check with your local council regulations to know that they are in compliance with the standards set by the council and also American Society for Testing and Materials(ASTM).
Whether it is fiberglass based asphalt shingles or organic felt or paper based asphalt shingles they should meet the specifications mentioned for the local climate conditions. For example fiberglass shingles should meet ASTM D 3462 specifications the organic shingles should meet ASTM D 225 standards. These are standard specifications for asphalt shingles made from fiberglass and standard specifications for asphalt shingles made from organic felt respectively.
Even though the warranty is an important consideration in the selection of the best roofing shingles it is not the only consideration. This is because even if there are warranties a particular product might not be the best solution for your requirements. And selecting a particular shingle based solely on warranty will not give you any assurance that the roofing system will deliver the best performance. If you are a person who believes that a warranty means some sort of binding agreement which needs to honored you will be better served if you go through the NCRA’s consumer advisory which has specific bulletin that addresses roofing warranties and pitfalls associated.
Underlayment is another area of conflict. Some contractors swear by the No.15 while others use only No.30. So, which is the works best when it comes to best roofing shingles. If you are using asphalt shingles then The National Roofing Contractors Association insists on a single layer of 15 asphalt-saturated underlayment for roofs that have pitches of 4 in 12 or greater. If you lesser slopes then NCRA recommends 2 layers of No.15 underlayment. If you are using higher quality and heavier roofing shingles which has a longer life projected then going for No.30 underlayment may be the best.
And no, two layers of No.15 underlayement is not the same one layer of no.30. The double layer of underlayment has to be laid with 19 inches of overlap. The double layer of underlayment is recommended by NCRA when the roof decks after low slopes of 3 in 12 or 4 in 12.
