APT Construction handles roofing installation and repair for residential and commercial properties in Molalla where roofs have developed leaks, lost shingles to wind, or reached the end of their functional lifespan. You may have noticed dark spots spreading across your ceiling after a storm, or you've seen granules from asphalt shingles collecting in your gutters, both signs that the roofing material is breaking down. This service includes full roof replacements, partial section repairs, and leak diagnosis using materials from Malarkey, Owens Corning, and CertainTeed, selected based on roof pitch, exposure, and expected service life.

The work begins with an assessment of the existing roof deck, flashing, and underlayment to identify areas where water has penetrated or where sheathing has softened due to prolonged moisture exposure. Damaged shingles are removed down to the deck, and any compromised plywood is replaced before new underlayment is rolled out and fastened. Shingles are installed starting from the eave and working upward, with each course offset to prevent water from channeling between seams. Flashing is fitted around chimneys, vent pipes, and roof valleys, then sealed with roofing cement to create a watertight transition. In Molalla, where heavy rain and occasional ice can sit on low-slope sections, proper flashing and underlayment become the primary defense against interior water damage.

Contact APT Construction to schedule a roof inspection and receive an estimate based on the scope of damage and material options suited to your building.

You will see that water no longer drips from the ceiling during rainstorms, and any stains that appeared on interior walls or insulation will stop expanding. The attic will remain dry, and you will not hear wind lifting shingles or flapping underlayment during gusts. Properly installed shingles lie flat without curling or buckling, and the roof line appears uniform without visible dips or waves that indicate underlying deck damage. APT Construction ensures that all fasteners are driven to the correct depth so they hold the shingle securely without puncturing through the surface, which would create new leak points over time.

Roof repairs may involve replacing a isolated section where a tree branch punctured the deck, or re-sealing flashing around a skylight that has allowed water to seep into the framing. Full installations include removal of all old roofing material, inspection and repair of the deck, installation of ice and water shield along eaves and valleys, and application of ridge vents to allow attic ventilation. This service does not include gutter replacement, soffit repair, or structural modifications to roof framing, though these can be coordinated as part of a larger exterior project.

Commercial roofing projects follow similar procedures but may involve low-slope membrane systems, standing seam metal, or built-up roofing depending on the building type and code requirements. Each installation is coordinated to minimize disruption to building occupants and to meet local permitting standards in Clackamas County.

Clients in Molalla often want to know how long a roof will last, what happens during the tear-off process, and how weather affects the installation schedule.

How long does a typical asphalt shingle roof last in Oregon?

With proper installation and adequate attic ventilation, asphalt roofs using architectural shingles generally last twenty-five to thirty years before requiring replacement, though moss growth and debris accumulation can shorten that span if not managed.

What is done with the old roofing material?

All torn-off shingles, underlayment, and damaged decking are loaded into a dump trailer and hauled away as part of the project, leaving your property clear of debris once the work is finished.

When is it better to repair instead of replace?

If damage is localized to one section and the surrounding shingles are still pliable with intact granules, a repair may extend the roof's life by several years, but widespread curling or granule loss across multiple slopes indicates the entire system should be replaced.

Why does APT Construction use ice and water shield even in areas without snow?

Ice and water shield provides a secondary waterproof barrier in valleys and along eaves where water tends to pond or back up under shingles during Molalla's prolonged rain events, preventing leaks that standard underlayment cannot stop.

What roofing materials work best for homes near wooded areas?

Algae-resistant shingles with copper or zinc granules help slow moss growth in shaded sections, and metal roofing sheds debris more effectively than asphalt, reducing the maintenance required in tree-heavy settings common around Molalla.

APT Construction provides inspections to assess roof condition, identify hidden damage, and recommend repair or replacement based on the actual state of the decking and shingles. Call to arrange an inspection and discuss material options that fit your building and budget.
