Roofing materials installation is critical to the looks and performance of the system. Atlas recommends professional installation by a carefully chosen installer.
Yes. Atlas requires the use of an approved underlayment with all our shingle product applications. Felt provides several functions. Although not water proof, felt is water resistant and acts as a secondary protection against wind driven rain. Felt also protects the shingles from resins from roof decking materials, and felt is a required component in meeting Class A or Class C fire ratings.
Atlas requires that your attic ventilation meet FHA and HUD Minimum Property Standards or a minimum of one (1) square foot net free venting area per 150 square feet of attic floor area, whichever provides the most ventilation. The ventilation area should be provided at both the eave and ridge area equally.
Yes, as dirt and debris (leaves, pine straw, limbs etc.) can hold moisture on the roof, you need to periodically check the roof and remove any buildup of debris, being careful not to damage the granule surface of the shingle. If left to build up on the roof, this debris can cause leaking and premature aging of the shingles.
No. Even in the winter, there is a need for proper airflow. Although the winter temperatures do not create heat build-up in the attic space, there is a need to rid the attic of excess moisture and reduce condensation.
No, this protective release tape you are referring to is placed on the back of each shingle to keep it from sticking to the shingle beneath while in the bundle during shipping and storage. This tape does not come in contact with the sealant during and after application. It does not affect the product performance after installation.
"Architectural" generally means the shingle has a three dimensional design and construction. I.E. - more than one thickness to provide enhanced aesthetic appeal.
"Metric" refers to the width of the shingle, i.e. 13 1/8" equals 1/3 meter. Shingles are generally either "imperial" (12" x 36") or "metric" (13 1/8" x 38 13/16").
A square is construction terminology for 100 square feet of coverage. (10´ x 10´)
Yes, Atlas does offer several roofing shingles which provide reliable Algae Resistance to ensure the beauty of the roof. For information regarding a specific shingle's Algae Resistance, please contact your Atlas Sales Representative.
A Peel and Stick” underlayment is a self-adhering underlayment sheet used to waterproof critical areas on the roof deck. For example, the Atlas WeatherMaster line of peel and stick underlayments are all self-adhering and seal around all the fasteners driven through during the completion of the roof covering installation – kind of like a “drive flat tire” – as the self sealing feature does it’s job.
Impact resistant shingles can withstand impacts from flying objects to a much greater extent than a common asphalt shingle. The impact resistant rating system ranks shingles’ resistance to impact into 4 levels – 1 through 4, with Class 4 as the highest rating level to impact resistance. The Atlas, the StormMaster series of asphalt shingles are rated as a Class 4 per the ASTM D2218 Test Standard and insurance companies in many parts of the US actually discount premiums when the StormMaster shingles are installed in place of regular asphalt shingles.
