Very good info. Found you on YouTube. Can you recommend any good commercial roof estimating programs that. You have seen for contractors? Also, can you recommend the best white cool roof coating that is tough and durable that can go over all types of roof membranes and withstand permanent pounding and foot traffic w out breaking? There seem to be many out their w big claims. Ty.
Contractors often use a spreadsheet for estimating, listing size and details in the first column, then multiplying the cost of each. With experience, figures become more accurate, and you learn how much labor to estimate.
List total number of roofing squares in the field or main roof area, and total number of squares for the walls, or perimeter detail, such as metal edging. Open areas are quicker to install than parapet walls. We estimate three times labor for walls. If you are installing a membrane, measure over the top of the wall and round up to the nearest foot.
Also count the number of details in the field, such as number of pipe penetrations, equipment curbs, skylights. Note equipment size, such as 4 vents per square, or large air handling units may be two squares each. We like to walk the roof to carefully observe conditions. We also always take a core sample to determine the composition of the roof and the condition of the insulation, vapor retarder, deck type (metal, structural concrete, lightweight insulating concrete). It’s always a good idea to take lots of photographs, and review special conditions back in the office.
We’ve known contractors skip the core sample to save time and then regret it later when they tear off around a drain and find multiple roof layers they didn’t expect.
You also need to know if there is trapped moisture, and whether the coating you apply is permeable to moisture vapor. We use a hand held inductance type meter to check several areas, and confirm with a core sample.
We always seal the sample area thoroughly, with a Sievert detail heat gun, trowel, and granular surface modified membrane where possible, or with EternaBond pressure sensitive PVC backed tape for single ply, after first cleaning and abrading the surface.
Companies like Eagle View, will prepare photographs, dimensions and details in a presentation package, if you prefer.
Our home base is in Southern California, and cool roof energy efficient Title 24 roof requirements result in nearly all new roof or coating installations being white or slightly off white.
Most all roofing materials are more durable with reinforcement, including coatings. We like to specify polyester because it flexes well in addition to imparting tensile strength.
You are right about claims for roof coatings, but they all seem to have benefits as well as drawbacks, so it’s important to understand all aspects in making a decision.
For one thing cured coatings can be very slippery when wet or damp with dew in the morning. We always include some type of walk pad, or grip surface near all roof access points to avoid the potential liability of a trades person slipping, falling backward, and hitting their head or worse.
Roofing membranes begin life as a liquid in the factory, but in a manufacturing environment you have more consistency in finish thickness. With coatings, they are field applied, specified in gallons per roofing square and wet or dry film thickness, and they are subject to more variation.
Most jobs are awarded to the low bidder, so it helps to have a written set of requirements, where everyone bids on a level playing field, and quality control inspections to check that the system is installed as specified, without skimping on materials or installation details.
Some coatings have a different color base coat to help in identifying full coverage, and since the base coat is not exposed to the elements, it can have less UV (ultraviolet) resistance and better adhesion for example.
Also if polyester fabric is embedded, one can observe the rate of coverage over the fabric.
With experience one learns to read the surface texture as a clue to how much material had been applied, and we often add a clause in the specifications that the contractor agree to disclose their material invoice to see the quantity of materials delivered to the site.
We like to see a long, proven history of in service performance in the field, for roofing materials and systems. Often problems develop near the end of the life cycle after prolonged weather exposure, installation irregularities or unforeseen circumstances. We have seen brand new companies offer thirty year warranties, but after decades of actual use, there is a better basis for confidence. If the chemistry, or additives are changed, we consider that a new variation.
We like to see fifteen years of use, and twenty to thirty or more years of proven performance make us feel even more comfortable.
One of the most basic roof coating materials is cold process asphalt emulsion. Hot asphalt is oxidized during manufacture to solidify the material into kegs which are broken apart and heated in a kettle. Cold process asphalt emulsions are never heated or oxidized so they retain better flexibility and don’t crack as easily. However, they do need to be protected from the sun, so we add a layer of acrylic surfacing.
The emulsions can be stabilized with bentonite clay, which has good resistance to standing water, but the acrylic surfacing can lift or peel in ponding conditions so we always add a layer of polyester reinforcement in the valleys, waterways, and around drains to bind the material in place. With the extra reinforcement and extra surfacing, the performance is vastly improved.
Some installations can be done in all acrylic. When looking at acrylic surfacing we like to check the safety data sheets (SDS-MSDS) for the amount of filler or calcium carbonate. The polymer resins give the material its resilience, but acrylic polymers are the expensive part, so companies add inert substances to be more price competitive.
Sometimes acrylic coatings are applied at lower cost as maintenance systems on a roof in generally good condition, where the stress points are reinforced with fabric, and the open areas just coated. This adds no tensile strength, and is not considered a membrane, but can reduce thermal movement, and shield from UV, and so extend existing life. You don’t use this method unless most of the roof is in relatively good condition.
Silicone roof coatings seem to be trending recently, and more companies seem to be offering them. They are resistant to ponding water, and can surface cure to become weather resistant quickly, but be aware that other materials do not stick to them, and if they are not performing, the entire roof may have to be removed. Primers are required over asphalt roofs to avoid yellowing and asphalt bleeding through the surface.
As with all coatings, surface preparation is important. The surface must be clean, dry and free of contaminants. Unreinforced silicone can tear. Manufacturers with a longer history of installation have learned how to install bond breakers at coping joints for example to achieve better results.
There are a number of other coatings, such as urethanes, coated sprayed in place foam, specialty coatings, and multiple ply configurations. We design coating systems to fit the roof conditions, building use, anticipated holding period, and available budget.
