"We Do Roofing Right"
About San Antonio Roofing Installation:

Having to deal with roof concerns is a certainty for nearly every homeowner at one time or another. However, many untimely roofing problems can be avoided by
annual inspection for possible repair needs. Or else including a new roof when undertaking a home improvement construction project.
With the exception of a few new rubber roofing products and the new innovation of metal roof tile and metal shingles, roof material and roof installation
techniques have remained pretty much the same for the last 20 or 30 years; with the exception of cost, of course, due to inflation.

Shingle Types:

Largely due to the cost factor, an asphalt shingle roof installed by San Antonio Roofing is by far the most common and popular type of roofing installed today.
Asphalt roof shingles are available in over 50 colors and about 12 different styles; ranging from the common 3-tab shingle, to architectural shingles, to T-lock
shingles. Asphalt shingle life expectancy is about 15-years.

San Antonio Roofing Company's most popular roof type is metal roofing; gaining popularity due to the fact that when properly maintained, quality metal roofing
will last 50 to 100 years or more. In areas with heavy annual snow accumulation, this type roofing is especially popular because of its snow shedding
characteristics; reducing the danger of roof collapse under crushing snow loads. Note: metal roof tile and metal shingles have not been in use long enough to
accurately determine life expectancy.

Cedar shingles or a cedar shake roof remains the choice for many homeowners. Mainly because of its visual aesthetic appearance and life expectancy, which
can be 50 to 100-years when properly maintained.
Other very desirable roof types offered by San Antonio Roofing include ceramic roof tile, concrete roof tile, and slate roof tile. Roofs made from these materials
have an extremely long life span when properly maintained; up to hundreds of years. They have been the roof of choice for the wealthy elite not only because of
life span, but the unrivaled attractiveness added to the structure.
There are several other roof material choices in use, especially for flat roof structures with only a slight or no roof pitch. Built-up roofing (BUR), also known as a
hot asphalt roof, uses multiple layers of membrane fused with hot-mop asphalt.
Modified asphalt (available in rolls) is heated using a torch as it is rolled out. When correctly installed, some asphalt will seep from under seams; an indication
of an adequate seal. EPDM rubber membrane roofing forms a single rubber membrane; this roof type is installed using a cold process not requiring hot
asphalt or torching.

About Pricing:

Regardless what type roofing is installed by San Antonio Roofing, it is usually priced by the square; a 10 X 10-foot area totaling 100-square feet. . Tearing off the
old roof and hauling it away costs an additional $50 to $150 per square.
Asphalt shingles are the most affordable type of roofing; $200 to $300 per square installed. Cedar shingles or cedar shakes are about $350 to $400 per
square installed.

Metal roofing price is higher than shingles, but usually lower than ceramic tile, concrete tile, or a slate roof. Prices for material alone without installation ranges
from $200 per square for standard metal, to over $500 per square for quality coated steel (which lasts 50 to 100-years.) Costs for metal roof options vary greatly
depending on installation difficulty; roof designs with multiple gables and valleys will add to the cost.

Ceramic roof tile, concrete roof tile, and slate are the most expensive options; usually over $1,000 per square installed. These types of roof tile add
considerable weight to the roof; as much as ton per square. Requiring strong roof trusses to bear the extra weight. Retrofitting your roof with heavier trusses to
support roof tile requires major roof construction; with cost significantly higher than $1,000 per square.

Roofing as a Project:

Some homeowners may possess the skill to undertake the do it yourself roofing project of installing asphalt shingles. Before starting, however, preparatory
work is required.
A new layer of shingles can sometimes be installed over the old, but never for a total of more than 3 layers. If tearing off old shingles, remove all shingles, nails,
and felt. Inspect the decking, which usually consists of 7/16 inch OSB or -inch exterior grade plywood. If there are areas of deteriorated decking, they must be
replaced. Use 16p nails to attach decking to roof trusses; one nail every 8-inches.

In extreme cases, the entire decking must be replaced. Oftentimes, the only prep work required after the old roof is removed and before new shingles are
installed, is to make sure all old nails or staples have been removed, for a smooth surface. And then stapling new 15 lb. or 30 lb. roofing felt to the decking or a
commercial grade underlayment.

This is done in runs starting at the bottom: new runs should overlap the top edge of the previous run by about 3-inches. After the felt is in place, galvanized edge
flashing is nailed along the perimeter of the roof. Shingles are nailed or stapled in runs beginning at the bottom edge of a roof, working toward the peak.
After the first run of shingles is in place, each subsequent run should be spaced evenly so that seams in the tabs are evenly offset with the previous run;
promoting maximum water shed. It may be necessary to snap a horizontal chalk line every few runs to keep them on a straight line.
To properly do valleys, a 16-inch wide piece of valley tin must be nailed vertically into the center of the valley. And then a run of shingles with no overlap should
be installed vertically over the tin. If the two sections of roof that meet in the valley are the same height, runs of shingles can be over lapped just beyond the
valley from either direction; complete one section first, before beginning the next.

When starting the second area, trim the runs in a straight edge in the center of the valley. If one section is lower than the other, runs on that section should
always be done first, running slightly past the valley. When runs are installed on the higher side, they should be trimmed to form an edge in the center of the
valley.

For the ridge cap, trim 3-tab shingles vertically, making 3 separate tabs. Start at the end of the ridge that is opposite to the direction from which prevailing winds
blow, with the bottom of the tab closest to the end of the ridge. Fold the shingle centered evenly over the ridge and nail into place. Proceed accordingly up the
entire length of the ridge, lining up each tab as you would for a run of shingles.

Nail in place so that the overlap covers previous nails, and lines up for a good seal on the asphalt sticky tabs. When you get to the end, trim the nailing part of
each tab off. Complete the task by placing a nail on each corner, covering the nailing part of the previous tab.

Outside temperature when installing shingles should always be at least 40 F or higher. This insures that enough heat will be generated on the roof to seal the
asphalt sticky tabs, ensuring that shingles will not become damaged or torn off during windstorms.

Most shingles are warranted against wind damage for winds up to 60mph. However, installing shingles during low temperatures may void this warranty. By the
same token, shingles should not be installed during too high temperatures. Excessive heat causes shingles to be too soft and susceptible to damage from
persons moving on the roof. The ideal installation temperature range is between 50 and 60 F for Metal, Shingle or Tile Roofing Systems
