The Best Time to Schedule a Roof Paint Session

As with any construction work, preparation is an important step before scheduling any roof paint session. Preparation will make the job easier and safer for everyone involved.

Good Weather Condition

Weather conditions play a vital part in applying roof paint. Roof painters must not only consider the material preparation but also the time when application of coating should be made. To maximize the result of coating, weather forecasts must be fully considered.

Most paint manufacturers recommend a temperature of at least 40 degrees at the time of paint application. They also suggest that paint products be stored in a warm, dry place with room temperature prior to application.

Painting on the roof is best done during spring or fall when the weather is not too cold or very hot. Latex paint could dry quickly and result to brush marks when applied in hot weather, while painting in cold weather could result to failure of the paint to stick well to the surface.

Two-Day Clear Weather

To give the paint sufficient time to cure, a clear weather forecast or no expectation of rain within 24 to 48 hours from coating is recommended. Problems may arise if the surface temperature of the roof is greater than the ambient temperature at the time of application.

Roofers must take into consideration these factors before applying paints—curing time, water ponding and the weather during and after application. Giving the coating sufficient time to cure is important, especially for the base product that is applied on top of the primer.

People generally disregard the cold weather when applying paints. They look at the high temperature for the day but not the actual temperature at the time of application or the substrate’s temperature. They should also take into consideration the low temperature the night before the application is made, as well as the maximum temperature during the day the coating is to be applied.

Time of the Season

Aside from the immediate weather condition, the time of the season when the coating is to be applied must also be considered. This observation is important when selecting the type of coating to be applied. Water-based paints demand longer curing or drying time. During fall and winter, you have reduced time to apply water-based paints because the sun comes out later and sets earlier than at other times of the year.

As to wind factor, this is taken into consideration only during the actual application when the probability of paint particles being carried by the wind to neighboring places is higher.

While you cannot spray-paint coatings at any time of the year, the paint will generally perform well under different conditions—heat, snow, hail or rain—when it was applied properly and left to cure at the appropriate curing time.

Roofing Materials That Could Withstand Arizona Phoenix Weather


One of the hottest cities in the US is Phoenix, Arizona. It holds the highest average temperature during summer among major cities with temperatures exceeding 100 degrees.

Because of the hot Arizona Phoenix weather, keeping cool is a primary consideration in house construction and repairs. Most structures use air-conditioning to keep the temperature cool inside. However, this is not the primary factor planners have in mind when constructing houses. Their priority is the roof, particularly using the correct materials and design to combat heat.

Builders choose from a wide selection of roofing materials. There are, however, certain materials that are better suited for places with hot weather like Phoenix, Arizona. Some of these are:

Terra Cotta and Clay

The cooling effects brought by terra cotta roofs are found not only on the materials used but also on the design itself. The curved or “S”-shaped roofing materials are placed in interlocking fashion to form beautiful arches. The spaces between the tiles allow air to freely flow and circulate, thereby rapidly dissipating heat and keeping the structure cool inside.

Rubber Membrane

A product of modern technology, rubber roofing is made from thermoplastic or ethylene propylene diene Monomer (EPDM), a synthetic rubber. The reflective properties of the rubber minimize heat absorption from the sun and keep the structure cool. Roofers get extra benefits from using rubber-membrane roofing – waterproofing the roof because of their seamless nature, which further prolongs the roof lifespan by preventing water from seeping in.


An affordable alternative to other roofing materials that many builders in hot countries prefer because it takes a long time to heat up from being exposed to the sun. Concretes are either poured to form slab roofs or installed as tiles. An added advantage from using concrete roofing materials is their fire-proof qualities. Roofers can enhance the cooling capabilities of concrete roofs by using light colors that reflect sunlight.

Slate Tiles

A very common roofing materials that originated during the 17th century. Slates come from natural stones and are available in light and earth-toned colors. The material’s reflective properties reduce heat absorption from the sun and keep the building interior cooler. Its global use can be attributed to its reputation as a cool material for roofing and availability in places where slates are abundant.

Solar Panels

Phoenix, Arizona with its arid weather and long sunny days is perfect for this type of roofing system. Solar panels or photovoltaic roof shingles do not actually reflect sunlight but absorb them and convert the heat into electricity.
